I have a remote server (running far, far away), which has a very important USB device plugged in (call T). Sometimes this device simply dies. If this happens, a simple plug out - plug in solves the problem on the spot. But to do that, somebody must be there physically, and do the plug out - plugin back with his own hands.

\n\n

This is what I would like to automate.

\n\n

My idea is to have another (USB or not) device, which can control the power line of another device, so:

\n\n
    \n
  1. it stays between T and my server
  2. \n
  3. can control the power of another USB device

  5. from the server I can control it remotely (ideal would be a char device, but any other solution is also acceptable).

I have read in many places online that a good smartphone camera doesn't solely depend on the amount of pixels. So, what else should I look in order to choose a good camera in a smartphone?

\n\n
\n\n

Sorry, to the community at the outset for not being clear to the specifications of my requirements; I was taking a photo of two rainbow(a very rare thing) at the time prior to twilight. I had Nokia 6700c(5 MP) & took the photo but unfortunately all but the rainbows were in the photo. I then took the photo using my laptop's front camera(HP 2000) & though it was only 2 MP, it could take the image of the rainbow but only a single one with fine grains around it(which after googling, I saw it as noise; thanks to @feetwet). So, 2MP performed better than 5MP! But still the photo was not clear enough to catch the image of second rainbow. Also, I never could take the image of a distant plane neither by the phone nor by my laptop; no matter at what proximity the plane was, it always appeared as dot in the photo but the laptop still performed well w.r.t. the phone. I like to take the images of clouds, sky, halos of moon, planes, birds hovering etc... I only wanted to know why my laptop performed better than my phone despite my phone being superior w.r.t. pixels. Also, I do want to know what to use in order to remove those grains or noise & take the image of rainbow at twilight or prior to that; for all that, is pixel important or something else?

\n", "Title": "What should I look for besides pixel density/count when choosing a smartphone with a good camera?", "Tags": "|performance|smartphones|", "Answer": "

Given your description of the shortcomings of your current camera, you want a camera with a large sensor (improved low-light performance and less \"noise\"), a very large optical zoom range, and a very wide wide-angle view.

\n\n

Measured in degrees, you need an 84\u02da field of view (or larger) for a rainbow, and a 5\u02da field of view (or smaller) for a distant airplane.

\n\n

Measured in \"35mm equivalent focal length\", you need a focal length of 19mm (or shorter) for a rainbow, and 500mm focal length (or longer) for a distant airplane.

\n\n

Zoom factor (numbers like \"10x\" or \"4x\") is meaningless without knowing the focal length/field of view of one end of the zoom range. You need at least a 25x optical zoom range; given that manufacturers usually bias their zoom range towards the telephoto end rather than the wide end, you may need to go much higher -- this will get expensive, and image quality at the extreme ends of the zoom range will be poor.

\n\n

Pixel count is generally one of the least important criteria when selecting a camera. One of these two images was created with a 6 MP camera, while the other was created with a 10 MP camera and scaled down. Which do you think is which?

We're looking for a new desk for an FOH house-of-worship setting. Right now we're using an Allen & Heath GL2200, 32-channel. We love it. It's done everything we want, but it's getting up there in years and we need more aux sends.

\n\n\n\n

Volunteers are (exclusively) using this, so it would be nice to have something with a not-terribly-steep learning curve. We're open to (and leaning towards) a digital desk.

\n\n

What do I need to consider? Does anyone have experience with something that would be a good fit?

Broadly-speaking, it would be silly to consider anything other than a digital desk at this point. That said, there will be a learning curve for people that are used to analog desks.

\n\n

I've been operating a Yamaha LS9-32 at church for the past four years or so, and have found it to be an excellent board.

\n\n

Now, for your requirements:

\n\n
\n

We have a fairly flexible budget, but system under $10k would be best.

\n
\n\n

Ours was purchased four years ago for ~$8500 US. I'm not certain, but logic says that it would be cheaper than that now.

\n\n
\n

We'd really need to have at least 10 aux sends, plus stereo mains\n output.

\n
\n\n

It has 16 aux sends in addition to the stereo mains.

\n\n
\n

We'd like to have more inputs, but we've gotten along fine with 32.\n This is a want, not a need.

\n
\n\n

The LS9-32 has 32 faders and 32 inputs on-board, and you can add an additional 32 inputs via an external digital input module if needed. The additional 32 channels are accessible on the desk by switching from the \"1-32 Layer\" to the \"33-64 Layer\".

\n\n
\n

It shouldn't be any bigger physically than our GL2200, otherwise we\n have to start moving things around in the booth and we don't want to\n do that.

\n
\n\n

The LS9-32 is roughly 35\"x20\". I wasn't able to find the specs of the GL2200 to compare size.

\n\n

In addition to the above, here are a few high-level features that I enjoy:

\n\n\n\n

Our sound staff is exclusively non-pro volunteers (including myself), and while there was a bit of an adjustment period, all of them were able to pick up the basics fairly quickly, and have been expanding their usage and knowledge of the board each time they're on the schedule.

I'd like to fit a gaming PC in my living room, and am looking into small form factor ones.

\n\n

I have been recommended the Alienware X51 series whose I appreciate the shape reminiscent of a gaming console, \nAbout Alienware one question I cannot find an answer for is if it would be safe to stack my PS3 on top of it (I do not have a lot of space in the living room)? I heard that the PC can get quite hot.

\n\n

I also want to consider alternatives.

\n\n

Are there other PC cases with shapes similar to the X51?
\nMost of the Mini-Itx have more like a \"brick\" shape, and seem harder to fit in the living room.

\n", "Title": "Recommended small form factor gaming PCs?", "Tags": "|gaming|pc|", "Answer": "

There are many many more options if you build your own system, and you can then be more flexible in terms of the components and the machine that you end up with. For example: are you looking to max out the graphics card? do you want to be able to upgrade said card relatively easily in a year?

\n\n

The other piece of advice is to not get too hung up on definitions. The HTPC cases are going to be more like what you are looking for in terms of looks and are perfectly capable of being gaming rigs. Take a look at the Silverstone cases as an example, and this one in particular for a fit in a living room:

\n\n

\"Lascala

\n\n

You might think that one is too big, after all it fits a standard ATX case, in which case you can check out the slim models etc. However, more space makes it easier to cool quietly and it looks just like an amp you might see as part of a normal home theater set up.

\n\n

Silverstone are not the only game in town either, Streacom, Origen AE, Lian Li, Fractal Design have some amazing looking cases and more mainstream players like Corsair (the Bulldog is coming soon as of writing this) have options on the way.

\n\n

In terms of pre-built systems places like QuietPC have been offering excellent (and quiet, of course) options that would certainly fit in your living room.

\n\n

As to whether to stack your components, I would always recommend an air gap and no direct contact - even though the heat will generally exhaust out the back a lot of the small form factor units are going to radiate heat from the case directly.

\n\n

I have cooked a wireless router while sitting on top of a PC and had overheating problems with an Apple TV for similar reasons. If you must stack, then always try to have the hottest component at the top.

These four are the main I/O that you see. What are the pros/cons for each?

\n\n

As far as I know HDMI 2.0 supports higher fps than earlier HDMI as well as that Display Port supports high fps. Besides that I'm not positive on why I would connect my monitor with a certain cable.

\n", "Title": "What are the differences between monitors inputs (HDMI, Display Port, DVI, VGA)?", "Tags": "|hdmi|display-port|dvi|vga|", "Answer": "

I'll start with VGA, which is, in my opinion, a \"standard\".

\n\n

VGA is an analog signal. This basically means that the quality will not be as great as cables that make use of digital signals, especially at high resolutions. The problem with analog is that noise often distorts the signal and the quality ends up not being as good. So in terms of quality, go for the other three.

\n\n

Digital signals do not have this problem because they are noise tolerant.

\n\n

DVI is a digital signal that has a few different connecter types and two link modes:

\n\n\n\n

Most adaptors are single link and support a resolution up to 1920x1200 whereas dual link supports up to 2560x1600.

\n\n

HDMI is the standard for HDTVs. It is also a digital signal and is therefore fully compatible with DVI-D and DVI-I. The benifit of HDMI over DVI is that is has the ability to carry audio as well as the video signal although it does require that your monitor has built in speakers. Recently, HDMI 2.0 was released and gives HDMI the ability to better deal with 4K (Ultra HD) displays at a higher frequency and FPS. If your display or TV has HDMI 1.4, you\u2019ll be limited to 3,820\u00d72160, 4K, at 30 Hz. However, if you\u2019ve got a video card and 4K display with HDMI 2.0, you\u2019ll be able to get 4K at 60 Hz.

\n\n

There's not much difference between between HDMI 1.4 and DVI besides the audio in the HDMI, which can be a real benefit depending on your setup and that colour ranges for HDMI go beyond the RGB spectrum which DVI is limited to. The only benefit of the DVI is the physical screws that support the DVI cable and help prevent port damage.

\n\n

DisplayPort is the newest of the lot and is aimed towards higher end monitors - newer and high-end monitors tend to have DisplayPort. Its designed to deal with 4K at higher FPS and Hz. DisplayPort is capable of 3840\u00d72160, 8K at 60Hz or 4k at 120Hz!

\n\n

DisplayPort looks like it's the way of the future, especially if you want 4K.

\n\n

Generally it depends on your setup (monitor and graphics card), what you can and can't use but for the future of gaming DisplayPort looks the way to go.

I'm considering buying new UPS for my PC. I'm hoping the new UPS can still hold power for around 15-30 minutes so my computer can properly shutdown. It should also come with surge protection. My PC came with Corsair 600W PSU and I'm using a 24\" BENQ monitor.

\n\n

Does the ICA UPS CE600 meet these criteria?

\n", "Title": "Personal computer UPS", "Tags": "|pc|ups|", "Answer": "

First, you should figure out what your actual power consumption is. A 600W PSU only draws 600W if the hardware needs it. You can get a Kill-A-Watt or similar monitor in the $15 USD range. You can also get a decent ballpark number from online calculators 1, 2, 3. Don't forget to include your monitor.

\n\n

The UPS you linked only supplies 300W. It gives 10 minutes as the backup time, and I'm going to have to assume that's at full (300W) power draw, as I don't see any other stats on the battery. So, no, it probably won't fit your needs.

\n\n

You could take a look at the APC or CyberPower UPS selectors to get an idea of what would fit your needs and the price range.

Raspberry Pi

\n\n

On the hardware side, there's an HDMI port; you can connect a monitor up to 1920x1200 (possibly through an HDMI-DVI or HDMI-VGA adapter, which costs barely more than an HDMI cable). There are 4 USB2 ports. The Ethernet port is 100Mbit/s, which should be plenty sufficient for a thin client, especially if it's displaying a web page rather than doing X11 over Ethernet. Wifi isn't built in; if you need that you'll need to get a USB wifi adapter. There's also a pair of sound jacks in case you need to plug in a microphone and loudspeakers.

\n\n

The small form factor and low power consumption (far less than anything you could get with an Intel processor) make it appropriate for environments with dicey power. There's no battery, though you can purchase one separately.

\n\n

The one downside I see is that the only form of storage is an SD card, which can be removed in an untimely manner. You may want to hold it in place with sticky tape or something.

\n\n

There's only 1GB of RAM, not 2GB, but that's enough to display a few web pages.

\n\n

The Pi has an ARM CPU. That means Windows is out (except a special version of Windows 10, but most Windows software won't run on it since most vendors distribute only x86 binaries), but almost all Linux software will work.

\n\n

Ubuntu 14.04 doesn't officially support ARM but there's an unofficial image. If you prefer a distribution that's officially mantained, you can get Debian jessie (there's also Raspbian, but it's optimized for the Raspberry Pi 1, not version 2 which is what you should get now that it's out). Ubuntu is based on Debian and pretty much all the system administration will be the same. Debian doesn't ship Ubuntu's Unity interface, though\u00b9.

\n\n

Both Firefox and Chromium (not Chrome) run on the Pi. There are also more lightweight browsers; try them with your web pages and see if they support all the features you need.

\n\n

The reference price for the RPi2 is $35, to which you'll need to add a bunch of accessories (USB power supply, keyboard, mouse, monitor, cables, USB wifi adapter if needed).

\n\n

There are other similar ARM-based boards that may be more adapted to your needs, for example if 2GB RAM is a strong requirement, or if you really want Gigabit Ethernet, or if you need wifi, etc. The reason I'm putting the Pi forward is that it's the one with the most literature and support out there.

Let's say I want to buy a cheap USB device which does X. I also want this device to be compatible with Linux.

\n\n

The problem is that in many cases, such devices may be generic or unbranded, and there may not be much information about them on the web to help me figure out if others have used that particular device successfully with Linux.

\n\n

Some examples:

\n\n\n\n

Are there any ways to (try) to determine if this device is compatible with Linux, before buying it ?

\n\n

I vaguely remember reading that one can look at the Windows drivers for clues as to the chips used, and then find if those are Linux-compatible, is this possible ?

\n", "Title": "How can I determine if a specific device works with Linux before buying it?", "Tags": "|linux|compatibility|", "Answer": "

The problem with those kinds of USB devices is that it's very difficult to know what chip they are actually using. Some devices in the same series might even use different components if the manufacturer was able to source a slightly different component at a cheaper price. They would then ship a Windows driver that supports the different variations of hardware components.

\n\n

It may be possible to glean something about the used chips by looking at the Windows or Mac drivers. What you would be looking for are strings that you could match against existing Linux drivers.

\n\n

However, before going through that trouble, you could do the following:

\n\n
    \n
  1. See if the manufacturer or seller has some mention of Linux compatibility, either in the available documentation, marketing material, or online forums.
  2. \n
  3. Search online for any of the marketing terms for the device to see if anyone else has already tried using it with Linux.
  4. \n
  5. Search in one of the Linux driver databases. There are several available (and some list other OSes as well), such as http://www.linux-drivers.org/, https://wiki.debian.org/Hardware, https://h-node.org/, and https://www.linuxquestions.org/hcl/.
  6. \n
\n\n

In general, if the manufacturer doesn't declare Linux support for the device, chances are it won't work very well even if there are Linux drivers. Then again, even devices with declared Linux support don't always work well or might not support all of the device's functionality. Ultimately, there are no guarantees and the only way to know for sure is to try. I've had some luck with shops that would allow me to bring a laptop and try the device in the store before deciding to buy or not. (In those cases I've mostly found that the USB device didn't work at all or was practically unusable.)

I'd like to boost my screen space and resolution. My primary monitor is currently a Samsung SyncMaster 2343BWX: 2048x1152 native resolution running off the DVI output of my GA-H77M-D3H motherboard.

\n\n

I haven't picked a monitor yet, so suppose I'd like to go up to 4k-class monitors:

\n\n
    \n
  1. Will a single output type – e.g., either DisplayPort or DVI-D – be adequate for all monitors and resolution classes up to 4k? Or would I want a card that offers both?

  2. \n
  3. Will any graphics card offering that output be adequate to the task? Or do I need to look for some additional minimum specs on the graphics card?

I'm not entirely sure about the AMD side of things but I'm running 4K now and I've been using nvidia GPUs and currently have a dell P2715Q.

\n\n

Connectivity:

\n\n

Generally DVI and VGA are nearly dead, they're getting phased out. We're in the arkward situation where support for HDMI is significantly better on TVs and entertainment devices, while DP wipes the floor with everything else on PCs. If you must standardise, use DP for PCs. If you decide to connect your console to your monitor (I don't judge!)

\n\n

On the monitor side:

\n\n

SST >>> MST. Its simpler, you get the full 60 hz refresh rate, and amusingly, \nits better supported by hardware in most cases. You'll need DP 1.1a or better but meh, as you'll see that's not hard

\n\n

Use mini DP or DP in, not HDMI - the standard for HDMI on PCs is an older standard, monitors may support the same standard and will only do 30 hz. In fact, if you must standardise, DP first, and DP for your best displays.

\n\n

If you're doing photo editing, getting a properly colour calibrated screen a good idea.

\n\n

If you can daisy chain, it'll cut your refresh rate in half. Not too recommended.

\n\n

On the computer side:

\n\n

I've gotten 4K output on a 660. In some cases I've managed to game badly on 4K, and the output wasn't the bottleneck, the ability to render the game was. I believe the 650 is the minimum GPU from nvidia for 4K (they have a handy list here) and anything better than that should handle it fine. 4th and 5th gen (and better) Intel video should be able to handle at least one 4K display. I can't find an equivilent chart or resource for AMD.

\n\n

Something worth considering is the modern UHD display is only 8 megapixels. While its challenging to render graphics, and you might need power to render video, it should probably be fairly simple to build a system that can handle photo editing

What type of hard drive should I be looking for a Playstation 4? I am usually partial towards SSD over traditional, but I am also open to the idea of hybrids as well.

\n\n

I have looked into Samsung 850 EVO and PRO SSDs and I have personal experience with SanDisk SSD on my personal gaming computer. These are a little out of my price range.

\n\n

There are many different sites that recommend HDDs, but I want to make sure what I am getting is going to have great life expectency along with great performance.

\n\n

Here is a site that has a comparison test between the three different types and their performance (too much info to post on here):\nhttp://www.ign.com/wikis/playstation-4/PlayStation_4_Hard_Drive_Speed_Test_Comparison

\n\n

According to the site, SSD has an overall better performance with the install time, boot time, and level load.

\n\n

If you would like to recommend companies or even particular drives, that would be very appreciative as well.

\n\n
\n\n

Update:
\nI am realized that SSDs are a bit out of my price range for 1TB. So I am going ahead and check out some 2.5\" HDDs.

\n", "Title": "1TB or more HDD for Playstation 4", "Tags": "|hard-disk|gaming|", "Answer": "

Based on personal experience (3 out of 4 failed, purchased several months apart) I recommend to stay away from the hybrid drives, as I will be in the future. A limited sample I know, I could have just been unlucky, but at this point I am cutting my losses with that tech. I think with the cost of SSDs dropping, they will have a limited lifespan as a viable product in any case.

\n\n

So far, I have not had an SSD fail (out of >10 purchased personally since 2009 in sizes from 75GB up to 512GB so far), though I have had one end up in a less performant state thanks to a faulty SATA cable. I have owned dozens of HDDs and had a handful fail, but nothing approaching the failure rate I have seen in hybrids so far.

\n\n

As of writing this, SSDs are coming in the $0.30 to $0.40 per GB range for sizes up to 500GB.

\n\n

The interesting thing here is that (as an example, plucked from Newegg today) the cost for a 250GB SSD from Samsung is currently $0.40/GB which drops to $0.35/GB for the 500GB model. At 1TB, that same drive comes in at $0.37/GB and it is on sale. This is the kind of profile we are used to seeing, however. Essentially, for the top end of any tech segment (4TB+ HDD, 1TB+ SSD at the moment) you will always pay a premium - same is true for CPU, memory, graphics, motherboards, displays etc.

\n\n

This is generally how I will do my SSD shopping - pick a couple of manufacturers with good reputation (Intel, Samsung), then decide on your required level of SSD (budget, consumer, enterprise - in Samsung terms EVO, PRO, Enterprise). Once you have that, look at the cost per GB for each size offered and look for the sweet spot - that will usually be one or two rungs below the top in terms of size.

\n\n

Actually this method will work for most things - CPU (use to be cost per Ghz but more murky now), RAM (cost per GB too), Graphics cards (depends, but cost per FPS in a highend game I play is how I do it), HDDs (cost per GB). There is always a sweet spot on the curve, and it will usually be a little below the bleeding edge, and frequently have sales on (so watch for them).

\n\n

I see from follow up comments that you are looking at HDDs because of price, so let's see where the sweetspot lines up for those.

\n\n

Edit: Updating analysis for 2.5\" drives thanks to comments

\n\n

Looking at 2.5\" drives that would give you a little bit of a speed boost (7200 rpm) and not worrying about the interface (the PS4 is limited to SATA II) one thing that was immediately obvious is that there is not a lot of choice, here is the cost per GB of a selection of Seagate 2.5\" 7200 RPM drives:

\n\n\n\n

That 500GB model was actually cheaper than the smaller drives, so hardly a surprise that they are the default for the PS4. It's worth noting that the SSD 1TB prices are \"only\" 2x the 7200 RPM hard drives in the 2.5\" form factor, so it's not as much of a premium as compared to 3.5\" drives (see below).

\n\n

Here is my original comparison, where I mistakenly profiled 3.5\" drives. It's illustrative, so I will leave it here for reference:

\n\n

I will pick a single brand that I have good experience with (Seagate), go for 7200 rpm drives, and not pay too much attention to other factors (warranty, cache etc.) since this is a rough estimation:

\n\n\n\n

The particular model I was looking at for convenience did not have 4TB/6TB sizes listed, but you get the idea - it looks like 3TB or 4TB is your likely sweet spot from a cost per GB perspective (as an aside: about one tenth of the SSD prices above), so I would look for well reviewed, reliable drives in that range and buy with confidence (for now). Just for reference, the 8TB 7200 RPM drives are rare and are coming in at ~$0.7 per GB as of writing this answer.

Due to the fact that TrueCrypt is \"not secure\" I've been looking for some other way to encrypt the data.

By the way...\nHave you heard about TOMB?

\n", "Title": "Should I buy an SSD with hardware-based full disk encryption?", "Tags": "|ssd|encryption|", "Answer": "

Whether the firmware has been compromised is a valid concern \u2014\u00a0it happens (it's been done for show, and it's rather rare but it has been found in the wild).

\n

But a bigger concern is whether the firmware has been programmed correctly. Many SSD firmwares don't implement secure erase properly. Should you trust them to implement crypto properly? I haven't seen a reliable study on the topic, but I've heard (private rumors in some security communities) that some \u201cself-encrypting drives\u201d are actually mere password-protected drives, with no encryption if you just bypass the controller. As a consumer, there's absolutely no way to know whether a particular device does it right\u00b9.

\n

The upshot is that I wouldn't rely on the encryption capabilities of a storage device.

\n

There's not much point in doing encryption on the drive itself rather than in the CPU anyway. This isn't the 1990s, most CPUs have plenty of spare cycles, of which encryption will only cost a little. Major operating systems come with native encryption: Bitlocker under Windows, dm-crypt under Linux, etc. If you have one of the cheaper editions of Windows that don't have full-disk encryption, or if you need an encrypted removable drive that's portable between operating systems, use VeraCrypt, the successor of TrueCrypt (which was discontinued because the maintainers didn't want to maintain it anymore, not because it was fundamentally flawed).

\n

\u00b9 Finding a way to attack a particular model can have a cost in the $10k\u2013100k range, so it's not something you can do casually \u2014\u00a0but once the attack is found, carrying it out on a particular drive has an incremental cost that can be in the $10\u2013100 range, or <$1 if it's a pure software attack on a buggy firmware.

A word of warning, which I said in a comment and will repeat here: don't expect other drones to be similar. There may well be some similarities between the odd few drone models - but control weights and sensitivities are always going to be different, no matter if they're tunable or not. A 1kg drone will respond faster to control input than a 10kg drone; that's just physics. When getting a new drone, always take some low-flying time in a relatively safe location so that you can get used to the new control feel.

In my case I have been using Raid 1 Mirroring with two disks on an onboard controller of a motherboard that recently dropped dead.

\n\n

Now I'm looking for a replacement motherboard, but I'm a bit worried about the data on the disks which I really want to recover. Since it was mirroring I half expect any SATA controller to just recognize the partitions and work automatically, but on the other half I guess it might not work that way. I don't have a 2nd system on which I can quickly test this and besides I'm concerned that it could be potentially dangerous to just plug it into any system. Some BIOS might just try to automatically initialize it and destroy some data?

\n\n

Can I just go ahead and purchase a new board without worries or should I figure out exactly what make / type and version of controller the board was using and try to find a new board with the same make / type / version RAID controller?

\n\n

For the record, my particular motherboard was a dual Xeon Tyan S2696. It was rendering some footage overnight and in the morning I found it dead. It does not even beep anymore, no fans, no leds, when powered on. The USB ports do get powered with 5V but it looks like there's a swollen capacitor between two PCI-x slots.

\n\n

EDIT:\nFor example, if I purchase a SuperMicro X7DB8+ as a replacement for the Tyan S2696, would I be able to hook up the old drives and read from them? They both use the Intel ESB2 Chipset, though I don't see and mention of \"zero channel RAID\" in the Tyan manual.

\n", "Title": "Are RAID controllers interchangeable? Is data recoverable with a different controller?", "Tags": "|motherboard|raid-controller|raid|", "Answer": "

Consider this logically, RAID controller has to record your config somewhere, if you had RAID-0 or RAID-1 for example. Some do that in own flash memory, others do that on the disk. In the latter case an area on each disk must be allocated to store configuration. There's no guarantee that different manufactures would pick same format. Same goes for checksums for higher-level RAID schemes.

\n\n

Good news is that RAID-1 is easy to recover in either case -- try whole disk, or if that doesn't work, find an offset and use data starting from that offset.

Trying the first costs you nothing.

For the longest time I've had the old Logitech Z313 2.1 sound system for my computer. After so many years of use and moving around, I'm looking for a more portable and more powerful system.

If you are willing to wait, you could get the Logitech Z333 Multimedia Speakers. As this hasn't been released yet, I can only go off of the spec sheet and online reviews, but this looks like it would fit your needs.

\n\n

This is a 2.1 speaker system that costs $80 USD. The subwoofer is flat-bottomed, has its own independent controller, and has a 5 inch, front facing driver. The sub is rated at 23 Watts while the two satellites are rated at 8 Watts each. While the website doesn't say exactly how big the drivers are for the satellites, the width of the satellites is about 4.25 inches, so I would expect the drivers are in the range of 2.5 - 3.5 inches in diameter. There are four 5 foot cables for this system (plus input cables): one for the power (wall to sub), one for each satellite (sub to satellite), and one volume controller (controller to sub).

\n\n

This system has both a 3.5 mm auxiliary input and stereo RCA inputs.

\n\n

With about half of your budget left, you add a Bluetooth Audio Adapter for $40 that allows you to stream music from any Bluetooth enabled audio device. With both of these items, you are still below your $150 budget (excluding shipping).

Please read this entire site which should quickly disabuse you of the notion that the technology is simple.

The reality is that high speed laser communication (ie, slow by today's standards 10mbps) is not at all trivial, and particularly over the distances you need. There are so many tradeoffs involved in the optical path alone that you could spend months or years trying to design something that would connect at all, nevermind provide a reliable link. For instance, do you select a lower divergence, which gets more power to the end point, but means that if either end moves more than a micrometer then the connection is lost, or do you have a larger divergence which makes aiming less critical, but delivers such low power you have a hard time receiving?

\n\n

That's just one of many, many trade offs and losses in the optical path engineering, and doesn't even touch the necessary low noise amplifiers and electronics, nor the physical layer interface to the network(s) or computer(s) involved in the communications.

There are different types of GPUs. It's a common misconception that any GPU will work for any graphics intensive task (video editing, gaming, etc) - not so. The M series GPUs in your question are more geared to be editing GPUs - their optimization was mainly focused on calculations relating to video and graphics editing, rather than more physics-based multiple-step calculations that are used in gaming.

For your intended use, there's not a massive amount of difference between the two - if you're editing videos, especially long videos, then the 2kM will perform far better - but if you're only intending on doing basic, occasional editing then the extra $100 isn't worth it.

In Asia, in particular Thailand and India, there are a lot of cheap and popular dual SIM phones. In fact most people seem to have dual SIM phones - I'm not particularly sure why, but I think multiple boyfriends/girlfriends may be partly the reason.

\n\n

These are all quite similar to the good old Nokia 3310, that is to say, a physical keyboard, and a small, non-touch, screen. These are often around the $40 mark or less, so well within your price bracket. The Nokia 107, for example:

\n\n

Some others are the Nokia 206, 208, 215, 220, 222, 225, 301, and 515.

\n\n

This is by no means the full list, but as you can see there are plenty to choose from. Whether these models are available in your country is another question, as they are obviously targeted towards the emerging nascent mobile phone markets, where lost cost is important. In more affluent countries, these may be considered \"throw-away\" phones, but they do meet your criteria, and do make for great holiday phones.

\n\n

Also, because there is no touch screen and a smaller screen, the battery life is longer on these phones in general, and only require a charge every other day, unlike most smart phones.

Is there any nice light-weight e-book reader which is easy on the eye?

\n\n

Preferred specifications include:

\n\n
    \n
  1. Display: Touch and (Something which is easy on the eye would be preferable)
  2. \n
  3. Decent battery life (I would be traveling a lot, so something which can run for weeks would be very good)
  4. \n
  5. Storage: Should be able to store at least 200 books at a time. (That's a threshold requirement. The more, the better)
  6. \n
\n\n

As I am a traveler, a device which is sturdy and durable would be nice for some quick reads during travel.

\n\n

Should support most e-book formats like epub, pdf, etc.

\n\n

As I am an avid user of Goodreads, a Goodreads app or integration would also help.

\n", "Title": "What is a good light-weight ebook reader?", "Tags": "|e-reader|", "Answer": "

I can second Kindle as an option (I have used an older model and a paper white) - for reading novels and other easily rendered text-only fare, it is a great product. The ability to function in direct sunlight as well as darkness without destroying your eyes is a huge advantage over other options.

\n\n

The Kindle app is available on other platforms too though (Android, iOS, desktop OS) and I have found it extremely useful to have a larger format, color capable reader for a couple of use cases:

\n\n
    \n
  1. Graphic Novels - if you like the format, then you will need more than e-ink
  2. \n
  3. Technical reading - diagrams, code samples, text that reacts poorly to being broken up all benefit from the larger format option
  4. \n
\n\n

I have also used Kindle on my phone (it syncs to the furthest read location on multiple devices) for those times that you forget your reader/tablet or are unexpectedly bored.

\n\n

Hence my recommendation, if you can afford it, is a multi-device approach for maximum satisfaction. Whether you go with Kindle or not, make sure that your chosen app and format are usable with several types of devices (syncing is so useful too).

\n\n

For travel, the phone is probably an easy choice (as long as your screen is reasonably sized). The tablet is a personal call - you can replace it with a laptop, but I find that awkward in restricted space (planes, trains) - decent tablets can also be loaded up with films/games etc. for the times your onboard entertainment options are poor. Personally, I leave the tablet at home for travel unless I know that I have a long flight where I need to do tech reading or I know the entertainment options are going to be horrible.

I would like to ask you about some external fingerprint scanner with a higher level of security than typical built-in reader.

\n\n

I have been using several notebooks with built-in fingerprint scanner but it was quite easy to cheat them (I cannot really rely on them as at the first line of defense). In many cases it was not too restrictive when it comes to accuracy of reading, even if the settings of the hardware were selected to the highest level of \"security\".

\n\n

Do you have any experience with external fingerprint scanners? Is it worth putting some interest in this topic? Could you recommend something? The price is not the most important, what is important is accuracy (not accepting fake but resembling fingerprints).

\n", "Title": "External fingerprint scanner with high fingerprint detection accuracy", "Tags": "|fingerprint-scanner|", "Answer": "

External device is per definition not secured...

\n\n

In a computer it's practically saying that you'll use USB. And USB is not meant to be secure.

\n\n

However you seem to have a very bad experience with internal ones which seems to be cheap ones and easily cheated.

\n\n

You need to be sure that they use your veins or infrared. For having a little of security with the USB thing : be sure that it's not a device that only send \"Yes/No\".

\n\n

Veins cannot be cheated by collecting the grease of the finger or a photo of the finger... Detection is thermal so an image cannot be presented. \nThe only way to cheat the detection is making a 3d metal sculpture of the structure of the vein of the good finger, heat it and show it to the system ... We can say that it's quite secure.

\n\n

However the USB part make the device vulnerable to man in the middle attack (witch is noticed because have an hardware between the usb port and the usb cable) and is also vulnerable to any simulation of the device (this part you can fix it by applying all the methods against brute force method)

If you want to consolidate remote controls, I always recommend a Logitech Harmony. There are various models that have additional features (ie. touch screens, how many devices it can control at once, quick setup, etc.)

One awesome thing about all models of the Harmony, is that they all use the same database for compatibility. You can search if your devices are available: here. Logitech boasts of compatibility with 250K+ devices across 7K manufacturers. Chances are high that it is compatible by default. If not, you can still program it using a device's original remote.

I am going to be building a computer for a college student. He is going into general engineering while he figures out exactly what he wants to do. The budget for this computer is about $1500 USD (just for the tower). This computer will be running Windows 10. He will be using this computer for school work and for gaming.

\n\n

From my previous question, it looks like I will be getting an Intel i7 5820K Haswell. The only problem is that it doesn't come with a heat sink. In my previous builds, the stock cooler was enough to get the job done.

\n\n

As I will not be overclocking the system, air cooling should be enough. The heat sink must fit the LGA 2011-v3 socket. The case that all of this goes in will be no smaller than an ATX Mid case.

\n\n

Since there are many options, I will try to narrow it down. I don't care about the noise level, as long as it doesn't sound like a jet engine. It should be more effective at cooling than the average heat sink. I am hoping that I can purchase one for less than $50.

And of course, temperature management is awesome for the price. This graph shows the 212 EVO's idle and load temperatures compared to others of the same capacity.

They have additional software related features you may find useful, though I can't vouch for any of those. These include a full PoS system, employee management, a market place and the ability to set up an online store through them.

Both methods accept Visa, Mastercard, Discover and American Express (with the same rates). Deposits go into your bank account within two business days.

I feel that was very helpful in getting rid of more \"stuff\", compared to previous years where I didn't use the reader.

I've got a 13\" laptop that I've had for a few years now, and it's been working perfectly until a couple weeks ago. It's a Dell Inspiron laptop.

\n\n

However, a few weeks ago, one of the fan has burnt out, and is completely unusable. As a result, the computer overheats fairly quickly, even on minimal usage. Whenever I open up a browser, or my IDE, I run a deep risk of overheating my computer: and as a result, it shuts down immediately.

\n\n

Are there any good computer fans, ideally powered by USB, that would work as a way to prevent my computer from overheating? It should be able to trap heat effectively from the right side to be vented out. I've got a price range of about $20, and it should be quiet, and durable (last me about 1-2 years) while I wait to get a new laptop :)

\n", "Title": "External fan for over-heating laptop", "Tags": "|usb|laptop|ventilation|", "Answer": "

although the answer from @JuanCarlosCoto was already accepted, I still must disagree on one point

\n\n
\n

..Bear in mind that whatever external fans you may feasibly buy and\n install will provide much less efficient cooling than an internal\n one..

\n
\n\n

An external fan, providing that is is not a blow-fan or fan pad , but an exhaust fan type, can be extremely effective - in fact much more than an internal one due to a much bigger facet surface and possibility to work in much higher speeds .

\n\n

Exhaust type fans ( sometimes called Vacuum Air Extracting fans ) , as opposed to blow-fans or pads, work on a different concept. they are actually sucking heat from the regular exhaust grill , instead of blowing air inside ( or in case of the pads - blowing air on the surfaces of the body ).

\n\n

Typology examples from google images ( but searching for the above terms will yield the same for your favorite search engine )

\n\n

Doing that - they are actually taking advantage of the integral / original aerodynamic and airflow design of the laptop, causing the air to enter and flow over the heat-sink / the processor / GPU in a ,much higher volume / minute capacity ( CMq/sec ) all that through the original air ducts .

\n\n

Several of my laptops have a desktop CPU combined with metal body and and are really hot at times , in fact - so hot that I was more than once inflected with a heat burn !

\n\n

All the cooling pads I have tried were somewhat of a hoax , never had any real influence ( 3-5 degrees Celsius ) - except making noise .

\n\n

But when I found exhaust fans - the effect was extreme . \nIn my tests , on an HP 8560p , after activating an exhaust fan the temperature on the integrated CPU sensor dropped 30 degrees in 20 sec ( 70's to 40's ) with immediate effect ( meaning the drop started in 1-2 seconds !! ) \nThe second drop took some more time ( about a minute ) but it was so efficient , that the fan had to be stopped due to over - cooling now !

\n\n

The test was made with a 10,000 max RPM external exhaust fan with 2 automatic adjustable speeds and 125.15CFM ( cubic feet / minute ) or 3.54 CCM ( Cubic Meter / minute ) sized 165\u00d780\u00d748MM 1.9W and cost 8$ !!

\n\n

Another advantage is that these type of fans do not insert dust into your laptop like blow fans, but actually sucking the dust out !

\n\n

And the best part - they are really cheap, and much more portable than the pads .

HDMI cable is the way\n to go. Then once I got my hands on a cable, the picture was horrible!\n Then I faffed about some more and found it is the picture ratio that\n has to be just right. After all this, I get a decent picture. Better\n user manual would be a good idea. I will probably do a youtube video\n review/tutorial just to remind myself how to set this thing up.

\n \n

I put a video onto a thumb stick and it played lovely. Hooked up an\n external hard drive that played well too. I also used it to display my\n ubuntu desktop. Text display is ok, but I would not like to have to\n read alot with it. I have my curtains pulled slightly on a bright day\n and it is plenty bright. One slight niggle is the power cable is very\n short so you do need an extension lead. The projector does make fan\n noise but I tend to mentally block it out once I'm watching a movie. I\n would say it is as loud as or slightly louder than my PC. The lense\n cover it came with does not stay on, in fact it is not the right cover\n for this projector. No problem for me as I'm not travelling with it.\n [...]

  There are similar FritzBoxes that add an analog phone port but only provide 802.11b/g/n 2.4 GHz wifi and less than 4xGbit Ethernet (FritzBox 7320, 7330, 7360). (No match. Esp. since now that most domestic phone connections are SIP anyway, I'd rather choose a native SIP phone instead of combining it with a FritzBox.) And again others that are the same but without phone and internal DSL modem (FritzBox 4020).

\n\n

  Only the relatively new FritzBox 4040 comes close again. Unlike the 3370, it does not have a DSL modem but an Ethernet WAN port \u2013 not an issue, as an external DSL modem can be connected to the WAN port when needed. Adding external antennas is also possible (see). It is however five times more expensive (50 EUR used on ebay.de right now) for basically no extra hardware features over the FritzBox 3370, except for \"guest wifi\". So my choice is quite clear :-)

What are the laptops which are most suited for data scientists and analysts?

\n\n

As we deal with heavy computations and also need to generate visualizations, something which can take the toll of it, would be recommended.

\n\n

Would be preferred if it can help in handling Big Data analytics too.

\n\n

Even though the analytics is done in the Map Reduce framework (or distributed computing), yet the computations are heavy and time taking and also slows down the laptop in most cases.

So, a laptop with features and OS which is most suited to handle such things gracefully is recommended.

An alternative which you should consider is moving to a server-client model for your calculations, performing the calculations on a powerful desktop and accessing the results remotely.

\n\n

The desktop, being relatively free from the restrictions of cooling and weight, can be configured to be almost an order of magnitude more powerful than the best laptop. Dual Xeon setups with 3 or 4 graphics cards come to mind.

\n\n

However, in order for remote access to work well, you need to have a reliable internet connection (data or wifi). If you can obtain a high speed internet connection that you can reliably access from any of the places you frequent, you should seriously consider that as an option.

\n\n

Many 3G/4G operators have data plans which you can use in your laptop either as a built-in or using a USB data modem, and the main stumbling block here is likely to be the coverage of their services.

I'm searching for a good monitor for my PC.

With these fairly low requirements, any of the mid-range ARM boards would fit, so you might as well go for a Raspberry Pi by default. (Model 2, the earlier models aren't worth the slightly lower price.) The reference price for just the board is $35, plus a power supply gets you \n\n

\n\n

The CPU is not nearly as fast as the latest Intel offering, obviously, but it's enough to run ordinary Ruby programs and do C compilations. (I wouldn't do big C++ or Java compilations though, but more than the CPU, the limiting factor is that there's only 1\u00a0GB of RAM).

\n\n

Since this is well under budget, you might consider a higher-end ARM board. 64-bit ARM boards (ARMv8) within your budget are starting to appear. (Of course, that's if you want 64-bit for some reason, not if you specifically need x86_64.) There's at least HiKey board is attempting to be a reference 64-bit board. It has a 1.2\u00a0GHz Cortex-A53, built-in USB2 and wifi, HDMI, 4\u00a0GB of onboard flash memory. There's also the cheaper Dragonboard 410C, with 8\u00a0GB of onboard flash, 4 USB ports and wifi. Unfortunately both have only 1\u00a0GB of RAM, at which point there are few benefits 64-bit CPU (there can still be benefits from other architectural improvements such as extra registers and cryptographic accelerators). I can't seem to find an affordable 64-bit board with 2\u00a0GB or 4\u00a0GB of RAM. You may want to start out with a 32-bit, 1\u00a0GB board now and use the rest of the price for a 64-bit board in a year or so if you find the need.

There are a lot of SBCs (Single Board Computers) similar or competitive to the Raspberry Pi that will fulfill your requests. They are pretty broad, and the market is pretty hot right now, so you have lots of options. Like most, I've played around mostly with Raspberry Pis of various sort. Aside from the B, B+, and 2, you have:

\n\n
    \n
  1. I have an ODROID C1+, and it has greater specs than the Raspberry Pi 2, with which it competes. I loaded Android to it, but it also has Ubuntu available.
  2. \n
  3. I have a Beaglebone (I don't think it's the black version though), but I have not done anything with it. It's somewhat competitive in features with Raspberry Pis, I think the original B and the B+. This device is usually meant to run headless, though they do have HDMI ports.
  4. \n
  5. I have a Raspberry Pi Zero, which is neat. I don't think it has any lower power conspumption, and it's required adapters may negate the savings of the board itself, but it is physically small, which may be a boon for your project.
  6. \n
  7. I have looked at the Banana Pi whilest browsing SBCs.
  8. \n
  9. Continuing with the fruit pies, is the Orange Pi, another full featured cheap SBC, though this one makes a point of being extremely low cost.
  10. \n
  11. The pcDuino combines an arduino and PC components and has various flavors including USB ports.
  12. \n
  13. The CHIP computer is a $9 SBC that hasn't started fully shipping yet, but it's another low cost, low power SBC sure to catch your eye. They should start taking regular orders in the fall if I recall correctly.
  14. \n
\n\n

SBCs all have slightly different features, which is good and bad. I have come across a blog that keeps up with all sorts of little devices called Liliputing. You could scroll through it and see if there are any other devices which might suit your tastes.

\n\n

EDIT

\n\n

Mark mentioned community support. I've seen some grumblings in the FOSS communities that people don't understand the allure of the Raspberry Pi, because there are more powerful, more feature rich alternatives. Keep in mind that while the community is large, a good chunk of it are n00bs asking the same questions over and over again presumably getting stuck on known issues. Those known issues can be with the OS, the board, or while they are trying to realign the squishy parts to wrap their squishy part around the concept of Linux and/or Linux around the Pi. My point is that a community of problems is not a beneficial community to the newcomer. I'm a newcomer, and this is my gripe. Also, I imagine that a lot fo Raspberry Pi How tos will work on other similar SBCs.

I am not sure how a $800 graphics card would go in a $1500 computer. One can technically buy it, but without a good motherboard, powersupply, CPU, RAM, HDD, and most importantly a case, it's just going to be a super expensive paperweight.

I would recommend something in the GTX 900 series, or the R9 200 or 300 series.

If you want the most power possible, the R9 390 and the GTX 970 are both incredibly powerful cards, and just about equal in terms of performance. The only downside is they are just above your price range.

Lenovo's Y50 is explicitly aimed at gamers. Thus,\n it is not surprising that it can render all current games smoothly.

The screen's maximum resolution (3840 x 2160 pixels) can only be fully\n utilized in rare cases. This option is at most possible in games that\n only have moderate hardware requirements.

My limiting factor from a video perspective at home is now my KVM. It is DVI based and supports up to 1920x1200 resolution. If I want to move to 4k I am going to need a replacement.

In stead of getting KVM switches from L1T, you should get your KVM switch from other providers, if you decide to go for the high-end DisplayPort 1.4 KVM switch solution.

\n

There is one very important spec. that all DP 1.4 KVM switches from L1T are missing - None of its DP 1.4 KVM switch models provide DisplayPort 1.4 EDID emulation and full-time EDID feeding to all connected systems/ laptops of the KVM switch. Some users said that feature is not important for DisplayPort KVM switch setups. If that is true then why the HDMI KVM switches from L1T are all come with standard EDID emulation and EDID feeding to the HDMI KVM switches they provided ?\nAlso, why L1T want the users of their DP1.4 KVM switches to buy the external DisplayPort EDID emulator to solve the lack of built-in EDID emulation issue. For 2-port DisplayPort KVM switch, if you use L1T KVM switch, you need to buy 4 of them for dual-monitor sharing model. The cost of 4 external EDID emulator will be $420 ($105/each)+ 4 x DP-DP cables ($15x4)$60 = $480 for adding the EDID for 2-port DP KVM switch from L1T.\nFor 4-port DP KVM switch, the cost for just adding EDID will be $960 (not including the 4-port KVM DP KVM switch and any other cables).

When running, I wear a GPS watch to track (in addition to my time) the distance I've traveled and my instantaneous pace. However, I've noticed that arm swing can have a bit of an impact on its readings. I don't have a substantial amount of arm swing, but I've noticed that I get a different pace when I hold my arm still than when I keep my arms moving normally (don't ask how I read it then).

\n\n

Is there a GPS watch that somehow accounts for this to produce more accurate data?

\n\n

I have some additional requirements:

\n\n\n\n

I'm somewhat flexible with these requirements, because I have yet to find a watch with this feature. If I have to sacrifice one or more requirements to find a watch, then I may do so. Feel free to bend them slightly.

\n", "Title": "GPS watch that compensates for arm swing", "Tags": "|gps|wearable-technology|", "Answer": "

tl;dr: arm swing is noise compared to accuracy of GPS

\n\n
\n\n
\n

Is there a GPS watch that somehow accounts for this to produce more accurate data?

\n
\n\n

No, there is not.

\n\n

The reason is among others that to get that level of accuracy for GPS requires significantly more than the GPS locator can provide.

\n\n
\n

The U.S. government is committed to providing GPS to the civilian community at the performance levels specified in the GPS Standard Positioning Service (SPS) Performance Standard. For example, the GPS signal in space will provide a \"worst case\" pseudorange accuracy of 7.8 meters at a 95% confidence level. (This is not the same as user accuracy; pseudorange is the distance from a GPS satellite to a receiver.)

\n
\n\n

It is possible the military, who are allowed multiple GPS channels could account for the noise associated with civilian GPS and create a watch this accurate. They may in fact have one. Probably not one you can purchase, however..

\n\n

Note that for applications that do need this level of accuracy such as farming or surveying all have some level of supplemental signal (such as RTK). These tools are all several orders of magnitude more than your $90 requirement - most are $1000-$10000 price range. They are also bulky and not likely to be portable. Many still have accuracy that is only in the ~10 inch range, too. If your arm swing is 2 feet their error is still nearly 50% of what you are wanting to account for.

\n\n

Also observe that not all running watches are created equally. I would suggest looking at this and picking one which has the best criteria.

\n\n

Now, onto my next point, which is instantaneous pace.

\n\n
\n

The pace should be accurate to the second - I've noticed that my current watch only does this in multiples of five seconds (e.g. it will rounds 7:03 up to 7:05).

\n
\n\n

First, keep in mind how pace is calculated.

\n\n

It is almost assuredly not polling the GPS signal multiple times every second and calculating instantaneous updates every quarter second (or whatever). Because GPS is a battery hog to get lightweight devices it likely is polling at an interval. A friend of mine with a PhD in networking technology indicated that once/second with a GPS intensive app is probably a good rule of thumb. More kills battery life.

\n\n

So lets say you are running a 7 minute mile. That's about 10 feet per second. Let's generously say that the accuracy of the GPS error is only +/- 3 meters (remember, 7.9 meters is the published accuracy at 95% confidence). This is a pretty significant improvement - a 7.9 meter circle vs a 3 meter circle. 3 meters is about 10 feet, and so this means that any calculation looks like:

\n\n\n\n

So clearly a 1-second pace doesn't make sense from a GPS perspective. Let's look at 5 feet:

\n\n\n\n

Ok, this is better, but still not super accurate, even with a 5 second polling interval. Keep in mind this is assuming that the GPS accuracy is pretty good that meaningful and repeatable.

\n\n

Let's also consider your arm swing. At worst, your arm swing might be 2 feet linear distance - out of 40-50 feet traveled in the 5 second interval. This is a small error margin, perhaps 2/40 or about 5% maximum error. But the GPS error is still 25% of this scenario.

\n\n

If we consider the 1 second poll, the GPS error is 100% and arm swing is still only 25%.

I have a rather advanced use-case that I need a KVM-type device for, and I was wondering whether such a thing even existed. I want a 3-PC setup; 2 desktops (PC1 and PC2) and 1 laptop dock (DOCK1). I want to connect 2 monitors, 1 mouse, and 1 keyboard. So far it's relatively straightforward, as I could just switch between the 3 devices.

\n\n

But here's the kicker; I'd like one mode to output PC1 video to screen1, extend DOCK1 video to screen2, and input keyboard and mouse to DOCK1. I'd like another mode with that video setup, but inputting keyboard and mouse to PC1. Basically I'd like to be able to switch between inputting to PC1/DOCK1, whilst continuing to be able to monitor each by outputting each one's video to one of the 2 monitors. However I want another mode where I can just go dual-screen with PC1 and input keyboard and mouse to PC1, and another mode where I can go dual-screen with PC2 and control it.

\n\n

Is there any KVM out there able to do this kind of thing? I guess I'm probably looking for some kind of programmable KVM which allows me to specify, for each \"mode\", which inputs are routed to which outputs.

\n\n

Oh and in terms of ports I want to use HDMI for video (or possibly DVI) and USB for peripherals; not VGA or PS/2.

I ended up using the Aten CM0264, which is a matrix KVM switch targeted at the small-office-home-office market; advanced, but not too pricey. While the software is rather flaky (don't bother trying to do a firmware upgrade; it doesn't work), luckily the firmware it came installed with works fine and the physical build quality is excellent.

\n\n

It had 4 device ports, just enough for what I needed (I'm plugging 2 video connectors in for PC1 to allow dual screen, and one connector for each of the other 2 devices). The ports vary between HDMI and DVI which is a bit odd, but luckily they are basically interchangeable using adapters as long as you only care about video rather than sound, and both use a digital signal (so no nasty analogue stuff like colour bleeding or fuzziness on the screen).

\n\n

Because it's a matrix KVM, I can independently change which input is being routed to which output console using buttons on the KVM, allowing me to display PC1 in dual screen mode, or just have one PC1 input and one PC2/PC3 input displaying (or even display PC2 and PC3 on the different screens). I can also independently switch keyboard and mouse inputs between devices by switching the USB routing (I plug the keyboard and mouse into the separate USB slots rather than the ones associated with video console 1, as those get switched along with console 1!)

\n\n

All in all I'm pretty happy with the solution, though I'd be screwed if I needed to add a fifth video input to the setup!

I'm planning to get a new (2nd-hand/refurbished) system for rendering large POV-Ray scenes. I'm using very large bitmaps as bump map and colormap.

A general rule of thumb is that a 100% increase in memory speed corresponds to a 5% increase in overall performance. This is because memory access is slow relative to the CPU, so CPUs and programs are designed to minimize memory access.

PSU recommendations are tough because it is a fairly quickly shifting market (not as bad as some, but nonetheless). I have personally had good experiences with several Corsair models, Enermax, EVGA and a couple of others over the years, so how do you go about picking one again?

\n\n

My lazy default is probably Corsair, but that is covered in other answers, and I occasionally want to look at other options and do my homework rather than assume that it is still the best choice. When doing so, I first check out a Power Supply calculator like this one to make sure I am beating my minimum required wattage by at least 20% - this gives me wiggle room should I need to add devices, or up the graphics card later, it also means that I am not over stressing the PSU even at full load.

\n\n

Next, I will decide if I really want modular or not, because there is usually a bit of a premium there in terms of price. Then I will filter down to the ones on the list with the best efficiency rating within my wattage and budget range. This is all a little theoretical, so let's walk through it with actual numbers.

\n\n

I guessed at a couple of things with your specs as a guideline and came up with a wattage requirement of 580W. Using my 20% rule above that rounds up to 700W as a minimum and I'll use 800W as a max to keep the resulting list smaller. Next, I plugged those requirements (along with the platinum 80 plus and modular requirement) into Newegg and got a list of just 8 candidates.

\n\n

What I am hoping for now is for one (or more) of those candidates to be from brands I know. If so, then I just do some basic due diligence by reading a couple of reviews, and make my choice. In this case my results give me two such options:

\n\n\n\n

Without a major price difference I would go for the Corsair, but the reviews on the EVGA look good, I've had decent experience with EVGA previously, and right now it is coming in at $40 cheaper than the 760 ($109 vs $149 after rebate) because it is on sale. That's enough for me, if I was buying the PSU right now, it would be the EVGA. Without the sale I would plump for the Corsair.

How can I find a replacement heat sink/fan assembly for a graphics card? Are there any standards as to size and screwhole placement?

I have a fairly old PC, to which I wanted to add a USB 3.0 card.

Do you have any other full size PCI-E slots available (x4 or x8)? If so, your x1 card will work in that slot without any modification and that may solve your issues from a slot perspective.

\n", "Title": "SODIMM: 1.3Vdc vs 1.3V", "Tags": "|memory|", "Answer": "

It doesn't actually make a difference.

\n\n

\"dc\", properly capitalized as \"DC\", refers to direct current. So 1.3 V DC simply means that the required RAM runs using 1.3 volts of direct current. (If you don't know about direct vs. alternating current, you can read about the differences here).

\n\n

Now, if you look at the power cable that's probably attached to your computer, there'll be a brick somewhere in the middle of it. That brick is the AC transadapter, which is a combination of an adapter and a transformer. It performs the function of transforming the incoming power down to a lower voltage that's safe for the computer (usually 12 V, though it can vary), and then adapting the AC current that comes from the socket outlet and through the transformer into DC current, because that's what computers work on.

\n\n

That's important because it means that any type of RAM runs on DC. Even if something specified AC for some RAM, the RAM wouldn't get AC because the only power coming into the computer and components is DC. Hence, a RAM package that's specified 1.3 V is no different in terms of power requirements from another that's specified 1.3 V DC.

I'm looking for MicroSD cards for my Mobius action cam. It's manual says the following:

\n\n
\n

For the best compatibility use cards with a class 4 rating if\n you have them. There is absolutely no advantage in using \n cards with a higher rating.

\n
\n\n

Despite of the manual above I have problems with a Kingston 64GB class 10 card (MBLY10G2/64GB or SDCX10/64GB) formatted by the camera to FAT32. (I was not able to find any SanDisk nor Kingston 64GB class 4 microSD card, class 10 is the minimum in this size.)

\n\n

I use MOV file format, 1080p 30fps and super quality. Using MOV file format also means that the last second of the previous file is repeated at the beginning of the next file when the camera starts a new one.

\n\n

Using Kingston SDCX10/64GB every file (except the first one) has a few bad frames between the 2nd and 10th seconds and there are 2-3 missing seconds in the video as well. MPlayer on Linux (as well as VLC) prints lots of these errors while I'm playing the first 10 seconds:

\n\n
Error while decoding frame!\n[h264 @ 0x7fb839d08440]AVC: nal size -1790556904\n[h264 @ 0x7fb839d08440]AVC: nal size -1790556904\n[h264 @ 0x7fb839d08440]no frame!\n
\n\n

I guess it's because of the one second overlap, the memory card could not cope with the double amount of data when switching files.

\n\n

I'm afraid plain 64GB class 10 cards could be also too slow for this scenario. So I'm looking for a MicroSD card which 100% works with Mobius action cam, MOV file format, super quality, 1080p 30fps.

I am going to be building a computer for a college student. He is going into general engineering while he figures out exactly what he wants to do.

I noticed that almost all power supply units (PSU) nowadays come with an 80plus label. This means that over 80 % of the electricity I pay for in my bills will actually reach my hardware instead of being wasted in heat, and that my hard work saving on the decimals of Watt there will make sense. Great, but now how do I choose if I want a PSU for a computer which is not too power hungry?

\n\n

Specific technical question: what's the most efficient PSU in a non-custom form factor, at a consumption of 100 W or 200 W, for an EU 230 V or 115 V home?

\n\n

Hypothetical concrete question with probably too much detail (skip if you understood above): what's the most efficient PSU I can use for my new mini PC/slim PC/HTPC/whatever, AMD APU based, either

\n\n\n", "Title": "What's the most efficient PSU for a mid-low power computer?", "Tags": "|power-supply|", "Answer": "

Personally I prefer the mini-ITX form factor, so I ended up choosing a mini-ITX A88X motherboard, with the A8-7600 AMD APU (65 W TDP).

\n\n

Consequently, I chose the Antec ISK110 VESA case, with 90 W power adapter. Antec claims an efficiency up to 92 %. Given the case cost some 80 \u20ac, it's really impossible to beat on the cost side; as for efficiency, the Gold unit suggested by Alpha3031 is around 89 % so it's probably comparable. There is also a case with 150 W PSU but it makes no efficiency claims.

\n\n

I've not found tests for such adapters, but Antec typically scores well enough in 80plus tests (see my other answer) so I don't think it would lie. The adapter is AcBel ADB002 and its external temperature is around 38 \u00b0C after several hours of (light) work.

\n\n

This solution addresses the use case provided by my question, but arguably not the specific question I made, because it's for 90 W power and not 100 W. It's also not suitable for A10-7850K and other 95 TDP APUs without downclocking. So I guess Alpha3031's answer is the most reasonable for the general case and I'll accept it in few days unless you suggest me otherwise. :)

First of all, I hope I came to the right StackExchange; I've seen some posts about laptop recommendations, so I think this is the right place to ask those questions.

\n\n

I'm thinking of buying a new laptop. My current one is a Samsung Sens X170 with a dual core at 1.30GHz, 3GB RAM, and integrated graphics (OpenGL 2.xx support). My requirements are:

\n\n
    \n
  1. $500 budget limit – I don't have a Windows serial, so about $600 including the serial
  2. \n
  3. Samsung – not because it's the best, but all the other AS systems are rather disappointing except Samsung in my country, and I'm a rather clumsy person...
  4. \n
\n\n
\n\n

I'm thinking of going to France next year, so I'm considering a laptop that is quite widely used in France (so that I can take AS easily?). In other words, I'll not limit my options to Samsung. ASUS seems to be doing OK here.

\n\n
    \n
  1. 11-13 inch screen(I'll allow 15 inch but it shouldn't be too heavy), durable, low electricity consumption is preferable
  2. \n
  3. I play games a lot, yes, but I usually play old games. My old Sens X170 even had a hard time playing Diablo 2 and DOOM with user mod. I'd just be happy if I can play games pleasantly that came in around 2005-2006.
  4. \n
  5. I don't do much work related to graphics, but I often do some simple programming (R/LaTeX/Python) and I'm willing to learn more about it.
  6. \n
  7. I do have a 2TB HDD so much space is not strictly needed.
  8. \n
\n\n

I haven't installed Windows by myself, but I think I can do it and it would be nice to learn how to do so. Actually, if installing Linux is not much of a hassle, I'm thinking of using that this time and pushing up the budget to $600. \nWhen old games refuse to be played on Linux, I can still use my old laptop instead, I'm thinking.

\n\n

Any recommendations are welcomed.

I've recommended it before but I'll recommend it again (and no, I swear I'm not an Acer employee): the Acer Aspire E1-572. It's a little over your specs in some ways, but it's a good laptop, especially for the price.

\n\n\n\n

Mine came with Windows 8 installed. Newer versions may come with Windows 10. Installing Linux is about as easy as it is on any > Win 8 machine - they don't like it, but it can be done.

\n\n

On programming capability: I use mine for some heavy programming (small games in Java and C#, plus utility Python 2.7 and 3.4), so you're sorted there.

\n\n

On gaming: again, I use mine for playing games that are more modern that what you'd be playing on it. I usually end up on mid-low graphics settings because of the lack of dedicated graphics card (it has integrated Intel graphics), but again, older games should be better for that.

\n\n

I don't have an exact figure for price, but it's under $600 - I got it for around \u00a3300, which was about $470 last time I checked.

I have a fairly known and consistent use-case. My laptop does almost no computational work. I do a ton of heavy computational work, but it all happens on big multicore servers which I access/control via Jupyter, SSH, remote desktop etc.

Adding more RAM might possibly help with your VM's. You should check task manager when running them to see if you are using most of it.

\n\n

When gaming, more RAM won't help. You'd need to be running two games, skype and a couple browser tabs to get close to using all that RAM while you're gaming. Your GPU, on the other hand, is a different story. Upgrading to an R9 390 ($330), or a GTX 980 Ti ($650), would massively boost your performance. Depending on your price range, the GPUs I listed would be a massive upgrade to your current GPU, for blender (when GPU accelerated), and games.

I'd also recommend using your old 760 as a PhysX card, especially if you actually play a game that supports PhysX. You could also just use it as a booster for Blender, as Blender supports rendering across heterogeneous GPUS.

First off, I doubt any active noise reduction (ANR) is going to beat out good passive noise reduction (PNR) in-ear plugs (\"stoppers\").

The last 3 headsets listed are aviation ANR headsets which I have used in high-noise environments (slow twin propeller and fast twin turbojet airplanes).

Which of these two graphic cards would be more suitable for gaming, what are the main differences between the two, which would you recommend from the two:

The reason is that the 960 is a newer architecture, and is still going to be available if you decide you're going to add another 960 in SLI.

\n\n

Bus memory is a consideration, but the way you're seeing it is not correct; there's more to it than that. For example, if you have a bus width that is more, but the memory tech is older (DDR3 instead of GDDR5), it automatically cuts the total memory bandwidth you gain in half. Depending on the memory clock, you may actually get worse performance with the DDR3 card, even though it has more bus width.

\n\n

Now, I agree the bus width of the 960 is lower, and both cards are GDDR5. But the newer Maxwell architecture of the 960 utilizes a color-compression technology that increases its effective bandwidth by around 28%, bringing it closer to the 760's. It also uses a newer anti-aliasing algorithm(MFAA) that is far less resource-intensive than MSAA that you'll have to use on the 760, again requiring lesser memory bandwidth.

\n\n

That said, I ask you this: what is the resolution you're using on your monitor? If it's 1920x1080(i.e. 1080p), the 960 will handle it irrespective of all these theoretical specifications. It's been designed to run modern games with that resolution in mind, and it's also more power efficient(176 W of power for the 760 vs 120 W for the 960), so the 760 runs 82C at full load and is loud, whereas the 960 never breaches 60 and is very quiet(both are very good things).

I am about to buy a new gaming PC and, checking for specs, I initially I was going towards the GTX 970 when I learned of the 3.5 GB issue.

\n\n

As far as I understand it, as long as my game does not use more than 3.5 GB, it will run smoothly but once that limit is passed, it will slow radically as it begins to use the slower 0.5GB chunk (the numbers I have seen suggest that it would go from extremely fluid play to unplayable almost instantaneously).

\n\n

Most comments seems to agree that unless I play it at 4K or use mods to load high-res textures, usually I will have no issues with that.

\n\n

Still, I am in doubt about upgrading towards a GTX 980; the price increase is considerable (~ 200\u20ac), the improved processing power would be welcomed but does not look like essential and, for the VRAM, the only difference is that those .5 GB are not slower.

\n\n

So my question is: if I decide later to use lots of high-res textures/increase the resolution, how will the VRAM difference affect it?

\n\n\n\n

For me, 0.5 extra usable GB do not seem to be a lot for 200\u20ac(NVIDIA cards with 6GB are out of budget), but I may consider it if this means that the performance will degrade in a more progressive way when full.

\n\n

I really do not have a favorite model for each GPU, but I have eyed this 970 (Gigabyte Gaming G1 Windforce OC) and this seems to be the equivalent 980.

\n\n

Of course, if there is something wrong/not so good about those specific models I would be willing to change, I only chose the first one because it comes with the GTX 970 \"preconfigured\" PCs, and the second one because it was easier to compare differences with the first one.

\n", "Title": "Different behavior of GTX 970 and GTX 980 due to 3.5 GB issue?", "Tags": "|gaming|graphics-cards|", "Answer": "

Yes, I agree that you should be in doubt about updating to a GTX 980. The card is not much different than the 970, and it is a lot more expensive.

\n\n

GTX 970 vs. GTX 980:

\n\n

Cores: 1664 vs. 2048
\nBase Clock: 1050Mhz vs. 1126Mhz
\nTexture Fill Rate: 109GT/s vs. 144GT/s
\nVRAM: 3.5GB vs. 4GB

\n\n

EDIT:
\nAnd to answer your questions:

\n\n

Q: Will the 980 behave just like the 970 (only that the 980 will have issues at 4GB instead of at 3.5GB)?

\n\n

A: Yes. However, it does have a few more CUDA cores. This will result in a greater overall performance.

\n\n
\n\n

Q: Will the game just crash if it tries to use more than 4GB of VRAM?

\n\n

A: I suppose so. Most games will try to regulate the amount of VRAM they use in accordance to how much you have. The reason the 3.5GB is an issue on the 970 is the fact that games think they can use all 4GB, and when they dip into that 'defective' 0.5GB, everything slows down.

\n\n
\n\n

Q: Will performance degrade in a more progressive way (slowing progressively, or just losing details from the textures)?

\n\n

A: I don't really understand the question. If you play at 4k and use high res textures, the game will start lagging and your fps will go down, because they game does not have enough VRAM to hold all the information.

I currently have four identically sized HDDs in RAID-10 on an Adaptec 8805. Unfortunately this controller can't do read/write caching of the array's blocks on SSDs attached to the RAID controller.

\n\n

I now have several SSDs (two right now, possibly expanding to four later) and would like to utilize them in this fashion without incurring the CPU overhead of doing it in software. I would use ZFS ZIL/L2ARC if my operating system were Linux/BSD/Solaris, but I'm running Windows, so that's out of the running.

\n\n

This is for a gaming workstation, not a dedicated server.

What options are available to me?

\n", "Title": "RAID card that can do SSD caching, 4kn, UEFI", "Tags": "|raid-controller|raid|", "Answer": "

There are probably CHEAPER ways to do this, but here's A solution:

\n\n
    \n
  1. Intel RS3DC050 PCI-Express 3.0 x4 Low Profile Ready SATA / SAS Controller Card\nhttp://www.newegg.com/Product/Product.aspx?Item=N82E16816117427
  2. \n
  3. Intel Upgrade RAID SSD Cache-with Fastpath for RS25 http://www.provantage.com/intel-rs3sc008~7ITE90QU.htm
  4. \n
  5. Intel AXXRMFBU4 RAID Maintenance Free Backup Unit with Super Capacitor Brown Box White Box https://www.amazon.com/Intel-AXXRMFBU4-Maintenance-Backup-Capacitor/dp/B01DIT7ZO8
  6. \n
\n\n

Notes: http://www.intel.in/content/www/in/en/support/server-products/raid-products/000008342.html

\n\n

Basically you get this RAID card installed, you attach the key to it, you fire it up, you configure SSD Cache and possibly also Fastpath as needed, you make your SSDs into a cache array and get it assigned to your RAID10 array, and off you go.

\n\n

You've now dropped a something near a grand into something that could be performed at a fraction of the cost if you'd just let it hit the CPU a teensy bit, but there you go, SSD caching on hardware RAID with a ridiculous number of SSDs and HDDs simultaneously in play.

\n\n

Finally, just for the record - \"This is for a gaming workstation, not a dedicated server.\"

\n\n

You emphatically do not need this and will not notice performance differences between this and a standard software-cached SSD+HDD RAID solution using something like PrimoCache. It is one of the most overkill solutions I have ever come up with at the behest of someone else, and I did it only to see if it could be done. You personally have no viable use case for this hardware.

\n\n

EDIT: I forgot to add in the cost of the SAS to SATA cables themselves; that's another couple dozen bucks at a minimum.

You have two options for surfaces - If you're a twitch gamer, go for the slick surface of the speed varient, if you want more control (and I'm guessing from the relatively low DPI, you're a precision player) there's the control version.

I need to buy a new laptop for my programming job. The problem is that I just don\u2019t like laptops! I have to get this because I need to travel and meet with colleagues and have to do some work on site. This implies that there is a good chance that this is not going to be my main computer in the future.

\n\n

On the other hand, I don't want to waste money (even the smallest amount) on a laptop that will be garbage in a year or so. If I have it I will use it, for as long as it lasts.

\n\n

My main jobs are performed in Eclipse, Netbeans and Android Studio. From what I have read around, these do not support multi-threading. So Intel would work better than AMD since (again from what I understood on the web) AMD has more cores, but single core speed of AMD is lower than that of Intel's. If I am using programs that can only use one core at a time then Intel should work better, right?

Well, my Klipsch Image S4 earphones broke yesterday. Had them for at least 4 years I think, and I put them through their paces, so it's understandable. They were amazing for their price though, and will be sorely missed.

\n\n

I'm saving quite heavily at the moment, and don't have another $90+ AUD to spare on another set of headphones for a while to come, hence me coming here. I'd like a recommendation for a good, but super-cheap pair of headphones, to get me through until I have some more disposable income next year or later.

\n\n

Comfort

\n\n

Preferably as comfortable as possible, especially for long periods. Over-the-head bands need to be padded, or else I really feel it on the top of my head after hours of having them on.

\n\n

Over-the-ears clips also bug me after long periods, but if you happen to have a recommendation for over-the-ears headphones which don't feel like they're cutting into where your ear connects to your head after hours of use, please feel free to share.

\n\n

Noise-cancelling (preferred)

\n\n

I know that for the price I'm looking at right now, this may be pushing it more than a little. But the main time I used my S4's was when I really needed to concentrate on a big project at work.

\n\n

This isn't a huge requirement, as having music to listen to at all can help me concentrate at times, even if it has to be played barely-audibly to make sure I'm not annoying co-workers. But if by some miracle there are cheap headphones out there which have any kind of noise-cancelling, I'd love to hear about it - both so I'm not annoying anyone, and so I can play my music at more than whisper-volume.

\n\n

Stereo

\n\n

Stereo sound, not mono. Probably accounts for almost all headphones/earphones nowadays, but again, considering my price range, it's worth saying this explicitly. I have many songs I love listening to partly because of just how well they utilise each individual speaker.

\n\n

Price

\n\n

The big one. I'd love something less than $10 AUD. To get the above features I could probably go up to $25 AUD. But less is definitely better for me right now.

\n\n
\n\n

I'm a huge fan of good sound quality, but just for now (until I'm able to splurge on something else) I'm willing to put sound quality on the back-burner. Of course, all the above preferences being equal, I'd love to hear in any answer what kind of sound quality the headphones do have. :)

\n\n

Edited to add: I'm sure everyone can pick up on my locality from the fact that I keep saying \"AUD\". But just to be clear: These should be able to be bought/ordered from within Australia. If I have to order them internationally, that may be okay. But please note in your answer if you think I'll need to order them from another country.

\n\n

You'll get 3 pairs of smooth earbud covers in different sizes and one flanged one, which is supposed to fit tighter.

Sound quality's decent, my phone's more of a limiting factor (I'm an audio snob). They're about as good as you'd get for the price range. It comes with that lovely rubber headphone holder and 'jewel case', and street price is ~30usd.

Remote control is below where the headphone splits. Its got 3 buttons, tho the volume buttons only work on some phones.

There's a few reasons. The specific nvidia line that mark mentioned on his answer's a bit problematic, and has a high failure rate. Its also roughly 7-8 years old, and its a little like putting a bike tyre on a bugatti veyron.

Depending on your needs a gforce 700 or 900 series, preferably midrange (a 960 upwards, but I paired my 'regular' core i7 3rd generation with a top of the line card, and its really good). If you have really have basic needs (and what you do does!) go with a lower end card, but preferably within the current or previous generations. The oldest I'd go is the 600 series.

What should you be looking for? HDMI's what you'd connect a TV with, and is standard. DP is the standard for computer monitors. Make sure your card has both.

\n", "Title": "Router + External Hard Drive (a.k.a. Home Cloud)", "Tags": "|hard-disk|router|", "Answer": "

If you really want an android app you should look at certain brands.\nBut if you don't need an app from the router manufacturer, basically any router with a USB and FTP-support should work. To answer your last question: There are routers that come with their own app, but usually you don't have to use that app (especially if FTP is supported).

\n\n

I personally have pretty much the setup you're looking for. I have a FRITZ!Box with a 5TB USB 3.0 HDD attached to it. So I can recommend a FRITZ!Box for this purpose but I'm sure there are other manufacturers providing routers with a similar service.

\n\n

All I had to do, was to set it up as a FTP server. Now I can access it locally in the network or from outside with my email and password.

\n\n

Now, to back up the data of my phone, I use FolderSync. Again, this is just what I use and can recommend, because I tested it. You can use any backup/sync tool that supports FTP. I just had to add my server and login to it and set up which folders I want to sync and where to sync them.

\n\n

The difficulty to set something up like this is depending on the manufacturer and what they provide. For me it was fairly easy.

Summarized, I wouldn't look for just a USB port. Look at the functions it has and if it supports something like a \"home cloud\". I also strongly recommend googling the product name and read some reviews before buying. You may also find instructions to set it up as a FTP for your specific model.

I'm currently writing a story where in 2005 a guy built a time machine out of a old Ford Mustang, a Casio ClassPad 300 calculator, some scrap, and a gaming PC, but the problem I'm facing is that I only started to follow the PC hardware market in 2010, and know nothing about older stuff. Hoping someone here could enlighten me.

\n\n

I have done some groundwork about this PC, but don't know how off I am.

\n\n

The PC can only run on a single core CPU, due to something about how the machine works, and it makes error when a dual core CPU is used, so I thought about using an Intel Pentium 4, but what about the AMD side, is there something better there?

\n\n

Other things I have thought about is 1GB of RAM, a 160GB HDD, Antec P180 Case, leaving out GPU and PSU, what was good back then?

\n\n

Another thing I thought about was using a custom Linux(Debian-based) as the OS, but how would that run on a '05 gaming tower?

\n\n

The PC's duty is via the Casio calculator, is taking the date and using some highly advanced calculation to reprogram the circuit that drives the part that makes the car going through time, and outputs a speed + RPM the engine has to go before it can go through time.

In 2005, the most powerful single-core CPUs on the market (and the wet dream of every gamer) was AMD FX-55 and later FX-57. For such a machine, 2 GB of RAM would not be unheard of, even in 2005.

\n\n

If you want something with more bang per buck that an ordinary gamer would be likely to have, an Opteron 144 mentioned in the other post would be a good choice (although it was introduced rather late in 2005). During that time, DFI LanParty motherboards with an nVidia nForce 4 chipset were quite popular for AMD rigs.

\n\n

As for the GPU, the nVidia GeForce 6600 GT was generally a popular choice during that time. Alternatively, you could go with an ATI Radeon X800 XL which was rougly on par with a GeForce 6800 GT (the \"Ultra\" version someone mentioned was made mostly for the press and availability was very scarce).

\n\n

As for the operating system - you definitely would not run any kind of Linux if you wanted to play games on your PC. But if your story is such that the guy re-purposes the PC for other stuff than games, then I guess it's OK. In addition to Debian, Ubuntu existed (from 2004) and some popular distributions were Mandriva (from Red Hat), Fedora and openSUSE.

\n", "Title": "Which would make a greater difference? Extra CPU or RAM?", "Tags": "|pc|memory|processor|desktop|", "Answer": "

In almost any case, with a proper, modern compiler, compilation speed will increase near linearly with the number of hardware threads on your system. In the case of Microsoft compilers, even running with 8GB will be plenty fine, as they are fairly stingy with memory allocation. However, on *nix, I have capped out even 16GB with parallel make and GCC.

\n\n

Modern CPU architectures are approaching peak performance, so even three year old top-of-their-class CPUs will still perform quite adequately compared to top-of-their-class modern CPUs. On the other hand, more RAM will always have an obvious and linear benefit.

\n\n

To address your specific issues, however:

\n\n

Of the two CPUs you specified, the difference in benchmarks is fairly marginal, with the only real big difference being the power consumption, as the i7 is rated to use about 2/3 the power. RAM, on the other hand, can be very useful, especially in the case of Java where the JVM just loves to gobble the stuff up.

\n\n

To give you an idea (Source):

\n\n\n\n

Personally, I would just go i5 and 16GB, but if you must upgrade one or the other, go for the RAM.

\n", "Title": "Recommendation for processors specialized for rendering and encoding", "Tags": "|graphics-cards|processor|rendering|", "Answer": "

GPU is usually faster, but I cannot find GPU benchmarks for Handbrake, so I'll recommend a CPU. Keep in mind that using the CPU I recommend, you need a new motherboard.

\n\n

I'd recommend an AMD FX-8320E. The 8320 because it's practically AMD's top of the line, and the 'E' because that basically means it's better binned, and they are both the same price at the moment.

\n\n

Other popular AMD CPUs such as the 8350, 8370, 9370, and 9590 are basically overclocked versions of this, but I can't bother to provide a link, so you'll have to search it up or not believe me.

\n\n

I recommend AMD, also, because of better price/performance ratio. As you can see in this anandtech benchmark, the overclocked FX-8320E ($125) is on par with the non-overclocked i5 4690 ($200). Overclocking Intel CPUs would probably surpass performance, but not by anything worth $200, which is already at your budget, so you wouldn't be able to buy a new motherboard.

\n\n

I know that some people are going to point out that it is hard to upgrade an FX-8320E to anything, due to an outdated chipset, but I don't think that 'dark fang' is going to be upgrading any time in the near future.

\n\n

Unfortunately, when using an AMD CPU, you are going to have the disadvantage of not having a built it GPU. You can either get a motherboard with on-board video, or a cheap dedicated GPU.

\n\n

I'd recommend a motherboard with a built-in GPU, which I know everyone thinks is terrible, but looked at his current iGPU. A nice, overclocking motherboard such as this, would be ideal for getting the most performance out of your CPU as well as getting an integrated GPU, but a more budget-friendly option could be this instead. I know option #2 isn't the greatest, but it is cheap. If anyone else has a motherboard suggestion, comment and I'll edit into my answer.

I started renting a VPS (\"Platinum X8\" VPS from Server4You), it has the following specifications:

\n\n\n\n

I am using this VPS for a single Minecraft server (i.e. not a network of servers), along with a Teamspeak 3 server & webserver (with MySQL server). The website runs a forum and will eventually only get moderate traffic (<100 connections at a time), & I plan for the Teamspeak server to have double the amount of slots of the Minecraft server (I plan to apply for a non-profit license when traffic picks up).

\n\n

As the VPS is on a monthly contract, I am able to cancel it and go elsewhere at any time; if the Minecraft server starts to outgrow the VPS, I can upgrade to a different VPS package (elsewhere, since this is the top VPS package at the provider) or even a dedicated server

\n\n

At the moment, the Minecraft server has 125 slots; can it go higher with the current hardware specifications?

\n\n

The Minecraft server is running some plugins, for example:

You'll find that you are more limited by RAM than CPU - especially with 16 cores. A 100 Mbit line will not be a limiting factor either.

\n\n

So, going by your RAM, you'll have roughly 16-17GB that you can dedicate to Minecraft after the OS takes the portion it needs.

\n\n

Experience has shown that you can get roughly 10 players per GB of RAM. In this case, you should be able to handle 160 players.

Am I doing this right? Will there be bottlenecks if I don't upgrade the CPU? Are there any similar components that I should look into?

\n", "Title": "Help updating PC for gaming", "Tags": "|gaming|graphics-cards|processor|", "Answer": "

The i3-2120 is likely to be a bottleneck to the system if you were to only upgrade your graphics card to a GTX 970. The i3-2120 is only a dual-core CPU (with 4 threads), while the i5-3470 is quad-core; many modern games benefit from multiple CPU cores (and some even require a four-core CPU, such as Fallout 4).

\n\n

The i5-3470 is much more efficient and newer than the i3-2120 (with a newer manufacturing process).

\n\n

It really depends on what games you plan on playing with your upgrade, for example Grand Theft Auto V will benefit from the i5-3470's performance, far more than a game focusing on graphical elements will.

\n\n
\n\n

For Star Citizen I, its system requirements seem to focus on the CPU rather than the GPU, therefore you'd definitely be better-off with the i5-3470 & the 960.

\n\n

Your motherboard has three PCI-E slots, so you might benefit in using both the 960 & 550Ti, with the 550Ti dedicated to PhysX. The amount of RAM you have is fine for gaming.

\n\n
\n\n

If you do not mind purchasing used parts, I'd recommend you get a 290X (eBay has tons of them) as you get more graphical power for less (in the UK, used 290X GPUs sell for around \u00a3160 while new 970s sell for around \u00a3200, making a used 290X \u00a340 cheaper).

\n\n

Ensure your power-supply is able to power a 290X- you should have at least a 550W PSU, with the recommended wattage being 600W. Bear in mind that if you do go down this route you won't be able to support the 290X with your current 550Ti.

\n\n

You might also be able to get the i5-3470 (or an even better CPU) used as well, along with the 290X. It really depends how much you're willing to spend on upgrading.

I currently have a small home-server, that runs a domain network & is the center of all file storage in our household. The drawback is that we need as much storage as possible, but the server's case only supports a maximum of four drives.

\n\n

Hardware of the server:

\n\n\n\n

Drives/partitions for \"Common Files\" are dedicated to file storage for non-critical files and are not backed up. All critical files are held on the OS drive, the entire drive is backed up to the 500GB backup partition of the 1TB drive. All critical files stored on the OS drive are automatically backed up to cloud services (namely Mega).

\n\n

I run a domain (ADDC) on the server so that any user-account/file can be accessed from any computer in the home. In addition to this, this configuration means that no data-loss occurs if a computer breaks.

\n\n

The server doesn't do much else than ensuring that everything can be accessed from anywhere within the house. It does run an SQL server (MSSQL) for local software development purposes, but it isn't used often. At night (from ~11pm - 6am) the server is shut-down, with it automatically turning itself on at 6am via a timer set in the BIOS.

So I'm looking into home plugs but the ones that give acceptable speed are pretty costly (as expected), and for the wifi part I've come across some Xiaomi routers that are WifiAC capable that costs about 30bucks but unfortunalety there are no reviews on them to see their actual speed.

\n", "Title": "Domestic wifi Network Management", "Tags": "|wifi|networking|router|", "Answer": "

I've a fair amount of experience with homeplug - I'm not going to recommend specific models since I have no clue if the sinoji plugs I use are available elsewhere or are the best option outside my current market. Wirecutter seems to like zyxel at the moment and are a good place for up to date reviews.

\n\n

I'd suggest getting homeplug 500 or better gear if you want 100mbps. Typically the advertised speed is for the whole network, and you never ever get line speed over homeplug. I have homeplug 1800 gear at the moment. Its got better noise rejection and reliability, even if realworld speeds are ~300mbps. They do work fantastically for me though.

\n\n

Stuff to look for? homeplug units must be plugged directly into a socket, no powerstrips. Get passthrough models, and plug a powerstrip to that instead. Passthrough models also filter noise. Wallwarts and other SMPS devices produce some noise that may affect signal quality, so plug them into a passthrough or a powerstrip on an extension cord.

\n\n

If you get cutouts - it might be due to a powerful motor like a washing machine. Move the homeplug unit.

\n\n

As for wifi, I currently have a 2 AP setup. If I was doing it again, I'd pick up \"professional\" grade APs - we used to have ubiquity APs in my last workplace and they were fantastic, with easy management. Ars technica has an in depth review of the current models here. They are 'pure' APs so you can hook them into your current router. I'd probably end up with a 3pack, hooked into more homeplug units or directly into a (better) router.

Features like heatmaps and the way they handle clients are far ahead of most consumer routers. At a certain level of complexity, these give you more options and information to optimise your network.

The second VPS server has the most resources available to it, therefore it would be the better option. However none of the servers you listed will be able to run all three servers properly.

\n\n
\n\n

Insufficient CPU

\n\n

It should be noted that you might run into problems with only two CPU cores. Try to go for one CPU core per server (so at least three CPU cores).

\n\n

VPSes are virtual servers, and thus you share resources. You will share resources with other virtual servers running on the physical machine, some providers guarantee a full CPU core (such as in one of the VPSes you listed), but not all do.

\n\n
\n\n

Server Slots

\n\n

You'd be okay with 16 slots to each server on the second VPS, but any higher than that and you'd need more RAM; 4GB would be the limit for the servers you want to host.\nAlthough the VPS will look like you have 6GB RAM (in the hardware specifications within the operating system), the extra 2GB RAM will only be available to you if the physical machine hosting the VPS has the resources to do so.

\n\n
\n\n

Operating System

\n\n

You almost certainly want Linux, and most providers of VPSes will only support the use of Linux and not Windows, due to the virtualizer not supporting it. It is best to pick a popular Linux flavour, I personally use Ubuntu 14.04 on my own VPS.

I couldn't find a provider that would co-locate a Raspberry Pi unfortunately, and co-locating it wouldn't have made financial sense as co-location costs ~\u00a360/month (for a 1U server) and for that money I could've rented the dedicated server for over a year.

There was also the option of switching ISP to one that told me (when I queried about the problem) their Internet connections are recognised as coming from the United Kingdom (incorrectly).

Small, but efficient. Would easily be able to run a VPN service with room to spare for running a (very) small website. High co-location cost.

Cheap, but good reviews of the company behind it. Would run a VPN service & a small website, but would have trouble running anything else. Would be solid & dependable.

I'm going to recommend the Be Quiet Shadow Rock Top Flow SR1 (\u00a343). Be Quiet, like Noctua, specialises in making very, very quiet CPU coolers. The advantage of this particular cooler is that it also helps keep the motherboard components cool. Pulling air down greatly improves airflow around the motherboard. It's also more compact than the D14.

\n\n

All three air coolers should be more quiet than the water coolers: The need for a pump in addition to fans negates the advantage of slower spinning fans.\nThe amount of sound insulation in your case probably makes the difference negligible though.

Some hardware RAID devices like this have internal RAM cache of about 1 Gb in size (faster than any SSD and no care about wear), use supercapacitor to flush this cache to the non volatile memory in case of power loss and also can use connected SSD as additional cache.

Such cards may be a good solution if your database has grown to multiple terrabytes in size so it is too expensive to place it completely on SSD with the required RAID redundancy.

I'm currently choosing parts for my new computer. I'm doing a lot of image processing and some of my algorithms are parallelized. In my free-time, I'm additionally up for some gaming.

\n\n

My current system, although already built in 2011, runs an Intel Core i7-2700K with 4 real cores (8 HT) and 3.50GHz base frequency. This guy still rocks and looking through today's CPU's kind of give me the feeling that physical limitations for faster machines are clearly visible.

\n\n

After reading and looking through the prizes, I thought I found my favorite CPU for the next system, which is a Intel Core i7-6700K 4GHz, but then I saw this comparison:

\n\n

\"compare\"

\n\n

Apparently, the Intel Core i7-5820K with 6 cores (which is the 5th and not the 6th generation) is in many tests faster. Important for me is of course, that the CPU supports DDR4 memory, which it does.

\n\n

Question: Taking into account that the prize is the same for both processors, I would be glad if someone had a recommendation. I'm keen to hear whether the difference in architecture (Skylake-S vs. Haswell-E) is somehow important for me. Probably there are other things I haven't considered.

\n", "Title": "Which Intel CPU? 3.3GHz x 6 or 4GHz x 4", "Tags": "|processor|processor-architecture|", "Answer": "

This could help you find your answer.

\n\n

As you can see for photo editing the 6700k is pretty good but not the best

\n\n

As you can see here, the 5960x does beat it quite often then not but it's also 3 times the price

\n\n

So between the 6700k and 5820k\nmulticore: 5820k is about 25% faster.\nsinglecore the 6700k is 23% faster.\nthese are from benchmark scores

\n\n

You cannot go wrong with either, noticeable advantages the 5820k has over 6700k is the memory bandwith which seriously quite high (Double actually) and the 2 cores (4threads)\nSo after reconsideration on my behalf, the 5820k might actually be the better choice since photo editing softwares are all 64bit and multicore nowdays. You can even overclock the 5820k more easily than the 6700k.\nBut then in gaming the 6700k takes the large, not by much but still noticable since it's single core performamce are pretty high. the 6700k is also power efficient and suports usb 3.1 natively (future proof)

\n\n

5820k would be my choice, with a setup than doesn't bottleneck it's performances. Atleast for the next 4-5years you're good to go.

Long story short, the motherboard of my 7 year old PC died and I'll need a new one. I plan to use it mainly for gaming (Elder Scrolls series, Fallout series, League of Legends, Crusader Kings, ...) with potentially getting into a bit of programming or video editing down the line.

\n\n

I'll be reusing the case, mouse, keyboard, monitor, and probably also the GPU of my old computer. The plan being that upgrading the GPU becomes my first major upgrade in the coming months.

\n\n

I'm happy to run my games at 30 fps, but I'd like that to also be true for the games I'll be playing 3 years from now.

\n\n

The main issue is that I'd like a computer that will last at least 4 years (preferably longer), but my budget is only around \u20ac500-600 ($550-660) and I'm concerned that won't be enough for what I want. So price is a very serious concern for me.

\n\n

The first order of business is choosing the CPU. I decided I want a quad core because supposedly that will be needed to run Fallout 4, but all I know about processors is that quad core is better than dual core and that unlike 15 years ago the processing speed is no longer the sole thing that determines how good a CPU is.

\n\n

I should probably also mention that I don't plan to play Fallout 4 on release, but instead pick it up during a Steam sale in a year or two. However, since I plan my PC to last longer than 2 years and it can't run without a CPU, I still want the CPU I get now to be good enough for it.

\n\n

Questions:

\n\n
    \n
  1. AMD or Intel? I'm more interested in cost efficiency than peak performance.

  2. \n
  3. I want to get something better than the bare minimum required to run FO4 in order for my PC to be somewhat future proof, but I'm not sure how far over the bare minimum I should go, considering my budget restrictions. The minimum requirements I found online are Intel Core i5-2300 2.8GHz or AMD Phenom II X4 945. Recommended processors for FO4 are Intel Core i7 4790 3.6 GHz or AMD FX-9590 4.7 GHz.

  4. \n
  5. Beyond the number of cores and frequency, what other properties are really important in a processor? In the sense of what should someone who knows virtually nothing about processors be careful about when chosing one.

  6. \n
  7. I just found out about the new Skylake processors that Intel released a couple of months ago. If I decide to go for Intel, would you recommend me to get one of these? My gut feeling is to go for the new thing because it will last longer, but is it really worth the price?

I agree with most of what Alpha3031 told you, but I think there are better options for your use case than the 860K. To explain, I'm going to go a little into the nuances of CPU lid design and hyperthreading.

\n\n

I recommend you look for a slightly more expensive 870K or 880K (also on the FM2+ socket) - and failing that, you should strongly consider a Haswell or Skylake i3 (sockets 1150 or 1151) clocked at or above 3.5ghz.

\n\n

The reason one such as yourself would care about the differences between the 860K and the 870K/880K are small, but worth the price difference in your case. First of all, whereas the 860K has paste TIM between its die and the CPU lid, the 870K and 880K, both Godavari refreshes of the Kaveri Steamroller design of the 860K, sport the superior metal flux between their dies and lids - this transfers heat between the die and lid much better than paste. This matters to you because you will want to make your CPU last longer than it probably otherwise would at stock speeds, so you will be overclocking, the success of which partly depends on how well you can dissipate waste heat from the CPU. With a good air or water cooler and the proper amount of overvolting, I would expect the average 870K/880K to reach somewhere around 4.6-4.8ghz, whereas it seems the 860K reaches lower top speeds on average; say 4.3-4.5ghz. Normally I'd say quibbling over a few hundred megahertz is not worth it, but you'll want everything you can get, I think. A potential alternative would be the weird Athlon X4 845 (FM2+), because it sports a superior IPC to the bigger chips as it is designed from the newer Carrizo Excavator architecture, but it is not unlocked and the newer arch only gives you 10-15% better performance at best. If for some reason you were unable to overclock and needed to stay with AMD (say to keep prices down), I'd recommend that CPU.

\n\n

The other option is, somewhat surprisingly, to spring for a low-end Intel i3 CPU. Many people disparage i3 CPUs due to their dual core architectures, but since i3s use hyperthreading, they actually operate 4 threads, which makes them quad cores as far as games are concerned - software only sees threads, not physical cores. The great advantage to choosing these more expensive Intel parts is twofold - you will get to put it on a motherboard socket with significantly more upgrade potential than FM2+ (FM2+ doesn't really have any CPUs with superior performance to the 880K while the 1150 and 1151 sockets support the vastly more powerful i7 and Xeon series), and as Alpha3031 indicated, Intel CPUs have much higher IPC, meaning they perform much faster on each core than AMD's offerings. While their overall performance tends to bring them neck and neck with AMD's Steamroller quad cores, they can't be beat for single thread performance at this price point, and you will see markedly better performance from an i3 over even an overclocked Athlon in games which utilize only 1 or 2 threads.

I've been searching for a simple Blu-Ray player. I've notice a lot of Blu-ray players are in the $60+ range, but also come with Wi-Fi/LAN capabilities, able play music, Netflix, all that stuff. I don't really want any of that. I just want to watch a Blu-ray movie and that's it for a reasonable price.

\n\n

Some things that would be ideal for me,

\n\n\n\n

If a USB one for a lower price is not an option, a standard one the connects to a TV through HDMI will be fine.

\n\n

I was hoping for the $20-30 range if those even exist.

\n\n

I was thinking a USB one would be cheaper, but the only ones I could find were ones that also wrote to Blu-Rays. Which I'm guessing made them significantly more expensive. (I also don't know much about Blu-ray players and if they can even be decoded through USB)

\n\n

In a nutshell, I just want to watch Blu-Ray movies for $20-30.

UPDATE

\n\n

So I've been searching a little more and giving this a little more thought.

\n\n

If I decide to bite the bullet and buy a $70+ Blu-ray player with all the bells and whistles, how easy is it to stream a Blu-ray movie over a network?

\n\n

I was thinking this would actually be a convenient solution for me. I would be able to connect the Blu-ray player to a TV and also be able to access it elsewhere in the house through the network.

\n\n

So, to make what I want a little more clear,

\n\n
-Blu-Ray player (Preferably less than $120 after looking at many prices)\n\n-Blu-Ray player able to be hard wired and have Wifi capabilities\n\n-Capable of streaming over a network to a PC running Windows 10\n\n-Software for PC (Free?)(If needed)\n
\n\n

To add a little more detail, both the PC and the Blu-Ray player will be wired into the same router, as I'm assuming streaming a Blu-ray over wifi could be pretty rough.

\n\n

If someone already has a set-up similar to mine, I would be grateful to know what you have/are using to do this already. I didn't want to get jumpy and buy a Blu-ray player and find some software just to find out nothing is compatible and I wasted my money!

\n

Wi-Fi/LAN capabilities, able play music, Netflix, all that stuff. I don't really want any of that.

\n
\n\n

The bluray specification requires that the player firmware is easily updated over time (mostly for copy protection features) and that bluray players include minimum functionality for internet coupled movie features. This is a simplification, you may be able to find older first generation players without networking, but I expect you'll also find they have a hard time playing some of today's newer movies and you may not be able to get updates for them.

\n\n

As such you won't find cheap bluray players that don't include networking features.

\n\n

Your best bet is to search ebay and craiglist for older used bluray players in your price range. Try to find something only a few years old, again, the much older players will probably have problems playing newer discs without some effort on your part.

If I decide to bite the bullet and buy a $70+ Blu-ray player with all the bells and whistles, how easy is it to stream a Blu-ray movie over a network?

The bluray specification does not permit streaming over the network. You will not be able to find a bluray player that does this for you. If you need something like this, you will need to set up a computer and use it to read the discs, handle the decryption, and stream the movie.

I recently needed to start using a third screen on my desktop, and the built-in Intel video will only handle two.

\n

For that purpose, I pulled an old ATI 4350 out of the closet. I barely ever used this card because it was very noisy, so I took the fan off and attached the north bridge heatsink from an old motherboard. It now runs at ~55\u00b0C with a little air flowing over it from a case fan. I'm curious as to how long it will last that way, but since it supposedly can tolerate 120\u00b0C (and in fact reached that when I first put the card in, with no fan and no heatsink) hopefully long enough. But I'm curious what I could have done without this not-very-ideal option.

\n

I don't need this screen for much -- no 3D, no video playback, mostly just generic GUI content such as viewing documentation. I have an HD monitor attached, so I do want 1920x1080 resolution, which I think requires ~16 MiB of video memory, since 1920 * 1080 * 3 (bytes/pixel) * 2 (double buffer) / 1048576 ~= 12 MiB, and I'm aware of embedded platforms that will display HD with 16 MiB of video RAM.

\n

I was surprised looking around that there doesn't seem to be anything out there to meet this kind of need; the lowest end cards I could find are still on a par with the 4350 (thankfully, there are more fanless options now) with 1/2 GB of video memory and 3D acceleration, and a $40-50 CND price tag.

\n

One of my concerns about these cards is power consumption. I don't have a watt meter, but the fact that the 4350 idles at 55\u00b0C whilst keeping 20g of aluminum very warm too implies it uses an excess of energy for my purposes. My PSU is fine, I just don't like pointless waste.

\n

Have I missed something? Is there anything more basic than this around? Like a low power1 $20 card you can attach a single HD monitor to?

\n

To clarify further

\n

Andy has already mentioned a bottom end 3D card. I'm aware of these, they are cheap and plentiful and there's nothing wrong with them, but I don't need to see a list of more of them here. I'm looking for something more specialized in the sense that it can't be a purely integrated chipset, since it's for adding a third screen to a mobo that already has this, but totally basic. I am sure it is possible to make, e.g., a 64 MB PCI card with a GPU that doesn't require any cooling or heatsink at all, and consumes <= 5 watts. But I suspect no one has bothered to do so.

I don't need this screen for much -- no 3D, no video playback, mostly just generic GUI content such as viewing documentation.

\n
\n\n

They don't usually have much hardware acceleration, but the drivers do typically support video playback at 30 frames per second full screen. Some of the better USB adapters support minimal 3D using the computer's processor for the hard work.

This is important because you might be surprised how many programs, such as CAD or even web browsers and document viewers use 3D.

a low power1 $20 card you can attach a single HD monitor to?

The one I listed at the top is often for sale right around $20. It's not a great piece of hardware, but if you have a price limit of $20 and are ok with the requirements (windows 7, 8, or 10) and fiddling around a little with the drivers, then it exactly fits your requirements.

\n\n

If you need something more specialized, then of course you're going to have to compromise some of your requirements, but at the moment it appears to meet your needs.

I am confused about which one of these processors to buy. I will pair it with two NVidia GeForce GTX 980 Ti (SLI). Also, I don't plan on too many upgrades and also I won't be overclocking 'too much'. The processors:

The 5820K and 6700K are the same price and also require DDR4 RAM and 99/170 series chipset motherboards, all of which are expensive. The 4700K and its supporting platform are comparatively cheaper.

The difference between 16gig (i'm assuming that's what you're going for in gaming) of DDR3 and DDR4 is of about 40bucks (in france) so I think you could go with the 6700k, since you're not into overcloking that much.\nThe 5820k would have been the better choice if you're gonna buy more memory (for editing stuff) than that (it has double the bandwidth). But for gaming that's waaaay more than you need. And the 6700k has native USB 3.1 support so a little more future proof.

\n\n

And you can probably find good deals on the 6700k in those upgrade kits. And lastly the 4790k actually does better than the 5820k in gaming in a few tests so if the price difference matters go for that one.

I will make the case that the ASRock Z97 Extreme6 motherboard is the best choice because of its feature set and price.

\n\n

The first thing to note about all boards under consideration is that they are absolutely top-notch. These boards represented the best each respective company could put together when socket 1150 was the leading socket for Intel. In terms of durability, reliability, and manufacturer support, these rank ahead of any other OEM motherboard for this socket in the desktop space. This leaves only price and feature set to differentiate them.

\n\n

Another poster has recommended the Asus Maximus Ranger vii motherboard. This was a very popular choice in its heyday because it had a good marketing campaign, Asus enjoys good brand rep, and because it was priced intelligently above many of its competitors, giving it the aura of an elite product SKU (which it certainly is). However, I think that for precisely these reasons, it is now certainly not the right choice for you. This board is not in much supply right now, so unless you want to buy used, it will be difficult to procure at a reasonable cost. My recommendation, the ASRock Z97 Extreme6, is still available on Newegg at a very competitive price.

\n\n

Though price seems to favor AsRock's board, this means nothing if AsRock doesn't bring compelling features to the table. Fortunately, AsRock does. Let's compare (please excuse the crappy pic):

\n\n

In almost all of the most important ways, these two boards are identical. They enjoy the same chipset, the same RAM slots, the same cooling schema, and a similar audio chipset. The important advantages of the Extreme6 are as follows:

\n\n\n\n

All in all, I think the features you get with the AsRock board outweigh the Maximus' brand name even at the same price, given that both these boards are well made. The added versatility is something that will make this board a workhorse for you or whoever else owns it long past the days when it can serve as a gaming rig's basis.

The title pretty much says it all. I'm assembling a budget gaming PC and decided for an AMD Athlon X4 860K processor and now I need to chose a motherboard for it.

\n\n

My total budget for the PC is \u20ac500-600 ($550-660).

\n\n

I'll be using my PC to play games such as the Fallout series, the Elder scrolls series, League of Legends, Crusader Kings 2 and such. I'm using Fallout 4 as a benchmark for performance. Ideally I'd like the computer to also be able to eventually run Elder Scrolls 6, but it'll probably take some 3-6 years before they make that one, which makes system requirements difficult to predict.

\n\n

In case it's somehow relevant, I'm thinking about using the opportunity to switch to Linux and Wine instead of spending money on another edition of Windows.

\n\n

I'd like to start out with 8 or 16GB RAM and have the option to upgrade to 32GB in the future.

\n\n

Integrated graphics card would be nice to have as backup if my GPU fails. This is mainly a concern because I might reuse the 7 year old GeForce 9600 GT from my previous computer to save costs now and get a new graphics card as the first major upgrade.

\n\n

I'm aware the old GPU will be unable to run Fallout 4, but I'm not planning to play the game at release. I intend to get it during a Steam sale by which time I'll have also upgraded to a modern GPU.

\n\n

I'll probably get all the components from here. It's a Slovenian website so there might be a bit of a language barrier for most of you. I tried running it through Google translate, but that broke the configurator tool. Essentially the tool works by selecting components from the dropdown menu, starting with a processor, then motherboard, then everything else. \"Mati\u010dna plo\u0161\u010da\" is motherboard. The components themselves have standard international names.

\n\n

The website lists the following motherboards as available (from least to most expensive):

\n\n
    \n
  1. ASRock FM2A88X Extreme4+, AMD A88 Mainboard - FM2+
  2. \n
  3. ASRock FM2A78M-HD+, DDR3, SATA3, HDMI, USB3, FM2/FM2+ mATX

\n\n

The description of numbers 1 and 6 says that the motherboard is intended for AMD processors that have an integrated GPU, which the Athlon X4 860K has not. I'm guessing that means I should probably pick one of the other eight, but I'm pretty clueless when it comes to hardware and have no idea which one.

\n\n

So finally, my question is which of the listed motherboards would be best for my needs? Or would you suggest a model not on the list?

\n", "Title": "Choosing motherboard for a budget gaming PC using AMD Athlon X4 860K processor", "Tags": "|gaming|pc|motherboard|", "Answer": "

I recommend the Gigabyte F2A88XM-D3H, which is an A88X motherboard, which should offer most of the modern features, with 4 RAM slots, which means an upgrade path to 32 GB of DDR3, and 4+2 phases which makes for decent overclocking headroom. The more expensive Gigabyte G1.SNIPER or Asrock Extreme6 bring only limited benefit, except more bells and whistles.

\n\n

I must admit the budget isn't nearly as restrictive as I initially thought, since you intend to reuse your GPU, which is the most expensive part of a gaming system, and you would likely have money to spare for extras like a Windows licence or a SSD. You don't quite have enough for an i5 though, which is the next step up on the intel side, and I hesitate to recommend the AM3+ platform, so if you have any leftover budget, I suggest you save it up for your GPU, or get a better cooler.

\n\n

The motherboard supports the Athlon 860K, though if it ships with a old revision of the BIOS , you may have to send it back to get it flashed with a F6 or later. Be sure to communicate with the store to see if they'll do it for you.

\n\n

Motherboards these days don't generally come with integrated graphics. If you want one, you'll have to spend \u20ac20-40 pounds extra for an APU. Those will perform worse because of the shared TDP, but with DX12, they may be able to help out a bit.

I have a customer who is looking to extend the output of a weather station into a second aircraft hangar at an airport. The vendor has approved doing this, but says that any solution we implement must be done \"after the monitor.\" The output is a single VGA port.

They have explained that this means the signal must go from the station to the primary display without any interruption in signal. I am looking for a way to use an ethernet based or even IP based extender in this configuration.

Does a monitor with a video-out passthrough exist? The requirement for uninterrupted signal to the main display leaves out the use of a splitter device, but I am wondering if they will allow a passive Y-Cable. We are checking on that, but I am looking for alternatives if that falls through.

Apparently the solution is one of two possible options. There is a DisplayPort standard called Multi-Stream Transport (MST) that was introduced with DisplayPort 1.2 (Wikipedia, n.d.). The other option is a display with a VGA in/out configuration. LG makes a series of monitors that provides this function, the N225WU-BN Cloud monitor, which is designed for use with Microsoft Multipoint Server 2011, but serves the purpose for this application (N225WU-BN, n.d.).

The answer is \"it depends\". The Tomshardware graphics hierarchy places your 9600 GT seven steps above a HD 4600, where three steps is the minimum worthwhile upgrade. However, the hierarchy is strictly about pixel-pushing ability. Your 9600 GT only supports DirectX 10 and OpenGL 2.1, and doesn't support OpenCL at all. In contrast, the integrated GPU supports DirectX 12, OpenGL 4.3, and OpenCL 1.2.

If you're doing things that require the new functionality (say, playing newly-released games), it doesn't matter that the 9600 is much faster than the 4600: the 9600 is simply unable to do what's needed of it.

For programming, I would recommend the i7. But because you are doing Premiere and 3D, I would go for the Xeon.

I am in the search for some recommendation on a good hardware component for building a mesh network with Arduino

\n\n

I am not experienced in building a mesh network. So all recommendations and guidance would be appreciated.

\n\n

My case is:\nI have 10 small robots that I'd like to connect, so they can share data like position and so on. \nUPDATE!\nThe robots are build with Arduino Nano, so it would be preferable with a solution that compatible with the Arduino environment.

\n\n

Also I'd like to log the data from the robots to a laptop. The ideal would be through some sort of USB unit, that can connect to the mesh network and log the data from the robots.

\n\n

I don't need to send commands over the network, but only statistical data like position etc.

\n\n

The range of the network would be in an open room, with a maximum of 100m2

\n\n

I would like an easy setup component, which have to be small, low-energy consumption and not expensive.\nI know these requirements might be general for all, but I stated them anyway.

Recommendations

\n\n

There are many different mesh networks I have seen being set up with the Arduino. Here I name just a few of the common ones.

\n\n
    \n
  1. Pinoccio
  2. \n
\n\n

According to the website,

\n\n
\n

Field Scouts talk to each other using a mesh network (called a Troop), using an extremely low-power radio. This makes them 14 times more efficient than standard WiFi devices. Slap a WiFi backpack on a Scout to make it the Lead Scout, and connect your entire Troop to the web!

\n
\n\n

This allows the data to be shared onto the Internet.

\n\n

The Radio of the Field Scout is over 2.4GHz using 802.15.4. I am pretty sure it will work in an open room. However the problem is you might have to redo all of the Arduino setup on the Pinoccio, but it is Arduino-compatible.

\n\n
    \n
  1. RF24Mesh
  2. \n
\n\n

It seems to be an easy to use library for Arduino, which you use when you attach a nRF24L01 to each of the Arduinos. However, there isn't much documentation.

If you are making a true workstation with fast speeds(so not for gaming) but for working with unreal 4 and DirectX 12, I would go with a Titan X because of the RAM benefit and the double float point RAM so you can be sure your not going to get RAM corruption while you are building your game world.

Should I go with a more cost effective, and 100% satysfying my current needs AMD FX-8320 (I'ts actually top 50 best value on CPU-benchmark) sacrificing extensibility, or some cheapest, but still extremly not-cheap, LGA2011-v3 processor, like i7-5820K (or maybe some Xenon?) to have the shiny LGA2011 platform, DDR4 support & and all the goodies of MSI X99 SLI plus?

The disk, memory and graphic card would be same for both AMD and Intel, and cost for all 340$, which leaves about just enough for used i7-xxx and new msi-X99 sli plus, or AMD 8 core (8320/ 8350/ 9590?) + motherboard and 3xx $ in pocket.

As both cards are quite similar (multiple SATA III, USB 3.0, more than 32GB of RAM), the choice boils down to the chipset: LGA2011-v3 (in MSI X99 SLI plus) or LGA1151 (in MSI z170 gaming pro).

The LGA 2011 platform and the LGA 1151 platform is designed for two different markets. The LGA 1151 is a mainstream consumer socket, designed for CPU's ranging from $100 - $350. The LGA 2011 socket is for the extreme enthusiast and prosumer purposes. CPU's for the LGA 2011 socket is around $400 - $1200 (please note that the $400 5820K only has 28 PCI-E lanes).

\n\n

Which one to choose depends on what your purpose is. If you're going to do normal day to day tasks, the LGA 1151 platform is enough. If you are doing to do prosumer things like video editing and 3D modeling, a LGA 2011 socket would be better.

\n\n

In terms of \"future extensibility\", none of them are good at it. Intel tends to release a new socket for each generation so to upgrade you would need to get a new board.

Super fast RAM - 16GB because why not? We want to be future proof right?

\n\n\n\n

Great graphics card in my opinion - really good performance - performance lies between the GTX970 and the GTX980 for around 350 bucks. I know that you wanted to buy a GTX 970 because you wanted to program for CUDA but when you really want the best performance for the best price your choice should be the R9 390. Alternatively you can use the GTX 970 if CUDA is absolutely necessary.

\n\n\n\n

Case fan for a good airflow.

\n\n\n\n

Solid CPU FAN - should keep your cpu cool enough from day to day.

That makes 1022-\u20ac where I am from so it should be ~1100$.

An i5 4460 would still be enough in most cases but if you want to be futureproof then a Skylake build won't hurt. Positive thing is that you can still enjoy your games in 1920x1080 resolution as modern cards support VSR/DSR.

Your requirements don't appear to be very specific:

\n\n

So, I will assume that you are fishing for possible solutions.

\n

There seem to be three simple options, depending on what, and how, you wish to want to achieve your objective:

\n

Use a mobile device

\n

As you say

\n
\n

I thought to create an app

\n
\n

assuming that you mean a mobile device (iOS or Andriod) app, then, depending on the actual size of display that you require, you could use a second hand, iPad, which are cheap and readily available on eBay. If an iPad is too big then an old version of an iPod (an iPhone would be over kill, unless you need a 3G connection to your server, which I doubt) would suffice. If the app is for Android, then a facsimile of an iPod/iPad would satisfy your needs, a second hand Galaxy Note or Tab, for example.

\n

Use a small monitor

\n

If you mean an application, rather than an app, for a PC based OS (OS X, Windows, or Linux) then taking your question at face value, the best (i.e., cheapest, smallest monitor), would be one of the monitors supplied by Lilliput, such as the 10" 859GL-80NP/C.

\n

For cheapness, you could use an old, vintage, CRT based Apple Color 12" Monitor, which has a resolution of 512 x 384. You would require an adapter, from Apple's monitor connector to VGA, but these are easy enough to find. You may, nowadays, have trouble finding a video card that supports it though.

\n

Use a Lapdock

\n

A Motorola LapDock 100 has a small screen, and accepts HDMI, which is fine so long as your PC has a DVI or HDMI output. Granted it also comes with a keyboard, but it would be useful for testing purposes, and could be used in conjunction with a Raspberry Pi - known as a PiDock. A prefect testing ground for your project, assuming that you are using a Pi. If you are indeed planning on using a Pi, then I would suggest the Motorola Atrix LapDock is a better solution than the Lapdock 100 as it has more and better features. Avoid the Lapdock 500, even though it appears on paper to be more fully featured, as it has some odd quirks that make it difficult to use.

\n

To my mind, this is your best option to prove your project, as it would only require a simple set of Python scripts to get it up and running, and should you, thereafter, want to cancel/scrap the project, you can use the Raspberry Pi and Lapdock for some other purpose, and hence save money.

\n

Build a custom solution

\n

If you only need to display five numeric characters then a monitor seems to be overkill, for both a cost and energy efficiency aspect. Much less power hungry, and arguably more of an interesting project would be to create a custom solution, using an Arduino and a Wireless or Ethernet shield (with the appropriate sketch to query the server) and an LED display, be that a 0.94" OLED, or a set of five 6.5" seven segment displays, or anything in between (again depending upon your size requirements).

\n
\n

If you can hammer down your requirements to be more specific, I can edit my answer accordingly.

I'm building a new PC but I'm stuck at one thing.

\n\n

What CPU should I choose if what I do mostly is programming & gaming?

\n\n

I saw opinions here and there saying Intel's CPUs would be good, others saying AMDs, but none seemed to give me a clear answer.

\n\n

The 2 options I would have are Intel Skylake, Core i5 6400 2.70GHz & AMD Vishera, FX-8350 4.0GHz.

\n\n

I'm open to any other recommendations, preferably good price/value ratio.

\n", "Title": "CPU recommendation: Programming + Gaming", "Tags": "|processor|", "Answer": "

My opinion is to buy the Intel if you don't care too much about the money.

\n\n

I had an FX-8150, and I can tell you that the 4 additional cores are not worth it. I did a lot of programming and gaming, and the 8 core were indeed useless, 4 would have sufficed.

\n\n

In addition, the AMD 8 cores are REALLY hot. The stock fan was noisy as hell, and I frequently hit 80\u00b0C (175\u00b0F), with only 1 core at full load (~15% overall). You will need an above average fan.

\n\n
\n\n

Now, if you want to buy something cheaper that the Intel, I think it would be better to buy an FX-4350, and not an FX-8350.

\n\n\n\n

It has the same per-core cache, and the same 8MB L3 cache than the FX-8350. All the other features are the same.

\n\n

I think it will perform better than the FX-8350 in a real situation, unless you really need 8 cores. The fact that it doesn't have an integrated GPU and use an older technology make it much cheaper than the Intel.

\n\n

You can also compromise with an FX-6350. With an FX-4350 or 6350, you can spend the extra money on a water-cooling, this will enable higher overclocking and certainly better performance than a 8350.

What memory would you buy, and why?

\n\n

Specific problems I consider:

\n\n\n\n

[EDIT]

\n\n

My use scenarios are:\nprogramming in couple of IDE opened simultanously (60% time), 100+ Mb data analysis (10%) and games like Fallout 4 (30%).

\n", "Title": "DDR4 memory - which one to choose", "Tags": "|desktop|memory|", "Answer": "

There are very few memory bound tasks for modern CPUs. The key factors to look for are capacity, cost, latency, voltages and speed, usually in that order. It doesn't really matter if a CPU doesn't support a RAM speed. You just need motherboard support and go into BIOS to activate the XMP setting, so that it'll run at the rated speed rather than the SPD speed.

\n\n

Without any further details about your specific workload (which is very important), my general recommendation, besides not to get a Z170 board unless you really need the extra IO, Smart Sound, or want to get a K CPU (overclocking), is to get 16 GB RAM straight away. It is very easy to use up 8 GB of RAM if you do more than one thing at a time, or if you're using anything that uses a lot of RAM. The price of DDR4 has dropped as well, so it is reasonably affordable to get 2 x 8 GB kits, in fact, cheaper than 2 x 4 GB kits of DDR3 last year: The G.Skill Ripjaws 4 series has a 2400 MT/s 15-15-15-35 kit for $74.99 at newegg.com. G.Skill is one of the largest manufacturers of RAM, and has a reputation for good quality. Their Sniper series generally has slightly more headroom, but it's just going to shave a few seconds off a 10 minute compression or video rendering, to name some memory bound tasks.

\n\n

Basically, \"overclocking friendly\" just means that the factory clocks are slightly less aggressive, and that you can increase them a bit more while still being stable. The PC* ***** naming is just a different way of naming DDR* ****. The number directly after the PC and DDRs is the version number, and the second number is the bandwidth in MB/s for the PC scheme, and the clock rate in MT/s (twice the real clock rate) for the DDR scheme. Since DDR RAM has a 64 bit wide bus and there are 8 bits in a byte, the PC number is just 8 times the DDR number.

\n\n

It doesn't really matter how you upgrade, just keep in mind that using memory from different kits may be unstable. The chance is low if they are the same model, but it's still there. Since you only have 4 RAM slots though, I'd just get a 2 x 8 GB kit and another when you decide it's not enough. Good luck.

\n\n
\n\n

Addendum: On memory timings

\n\n

Memory timings tell the CPU how long to wait before expecting an action to be completed on the memory chip, and in SDRAM (clocked + refreshed RAM), is measured in RAM clock cycles (which is half the DDR number). Memory is arranged in rows, which are divided in to columns.

\n\n

CAS Latency determines the amount of time the CPU to wait after issuing a read command before actually reading the data from the output pin. If this is shorter than the time it takes for the RAM to respond fully, what is read is a voltage that is transitioning between the previous voltage on the output pin and the desired one. This is bad and sometimes causes the computer to crash.

\n\n

But CAS Latency is the full latency only if the right row is already open! If there is no row open, the CPU has to issue an Activation command first, and wait. This is the next number, tRCD, the RAS to CAS delay.

\n\n

The third number is tRP. The Row Precharge time is the time you need to wait between a Precharge command and an Activate command; the time it takes to close a row, if you have the wrong one open.

\n\n

Finally, the last number is basically CAS + tRCD, and then a bit more. It's the minimum amount of time a row can be active. There's a bit more again to let the memory finish passing on the voltage.

Using eXtreme Outer Vision's eXtreme Power Supply calculator, the power consumption of your build comes to about 390 W. With some overclocking, this becomes 470 W. Any decent 500 - 550 W PSU should handle the load fine for several years with no problems, even if you do overclock a bit later.

\n\n

I personally won't recommend the Corsair VS series, as it uses poor quality capacitors. Here are my recommendations from the site you posted.

\n\n

Antec 550W VPF550 EC

\n\n

The Antec VPF line is a relatively new series manufactured by Delta Electronics. It has Japanese capacitors and a 24 month warranty. Currently it is priced at 249 z\u0142. Non modular, but that isn't much of a problem for lower capacity PSUs, it also has 80 + Bronze certification.

\n\n

XFX Core TS 550W

\n\n

The XFX TS series is a budget series manufactured by Seasonic (one of the best manufacturers of PSUs out there). It also has Japanese capacitors and a 60 month warranty (that's right, 5 years). It's one of my favorite recommendations: High quality at a relatively low price. Again, has 80+ Bronze certification and is non modular.

\n\n

I took some time to shop around on some other Polish sites (which was a breeze as soon as I figured out what the word for Power Supply was), and I found the TS selling slightly cheaper at komputronik.pl. Overall, I think both PSUs will fit your needs, and it is up to you to choose the one you like better. Good luck.

My recommendation then would be to build a budget system, picking out the processor/chipset you want to keep and making sure the motherboard is something that will be good for awhile, as that is the component that is the biggest pain to upgrade. However, if you thought just upgrading the graphics card would get you by for awhile, then you could buy that as most cards will probably work in the system. Then you could take the card into a new build down the road when you thought you were ready. Keep in mind that you are more likely to bottleneck somewhere else in this instance, with a modern GPU but much older CPU and RAM.

\n\n

EDIT: In response to the question update:

\n\n

Motherboard and processor: You first need to decide on which socket you want to use. There are a couple viable options: LGA 1150, LGA 1151, and LGA 2011. Of these, LGA 2011 is older, but has seen a recent update (LGA 2011-v3, which is not compatible with the older LGA 2011 socket); LGA 1150 is the least advanced but the most available; and LGA 1151 is the newest, but also more expensive. The good news is that virtually any modern Core i5 or i7, and a good amount of Core i3s, that fit these sockets would be faster than a Q6600. As far as future upgrades:

\n\n\n\n

Graphics: According to this GPU hierarchy, The lowest end card that is an upgrade that is nVIDIA is either a GTX 660 Ti or a GTX 760, but neither are readily available (old). The best value in a low end nVIDIA card is a GTX 950, which will run you about $135-150. An integrated Intel card could provide you with more performance, but it wouldn't be much of an increase over your current card and even the cheapest dedicated GPUs avaliable now would outclass it.

\n\n

Conclusion

\n\n

You have two routes that I see as viable both now and longer-term: save a little money now and go with LGA 1150, or go with LGA 1151 and have a longer viable lifespan. Keep in mind that you can still build a really really good machine on LGA 1150 that will still produce impressive gaming results for years, but if you will want the possibility to stay with the latest and greatest, LGA 1151 is probably a safer bet.

An SSD would be a good idea to put the OS on, as well as a few programs/games that you want to start up fast.

Another thing that will help a lot when gaming on high quality is graphics memory. If the game textures are big, they can't fit on graphics memory, and are stored in normal memory instead. That makes things a lot slower.

You should probably get a reasonably new graphics card with at least 4GB of memory on it. Something like an r9 390, or 380 if you don't have the money.

I've recently acquired a GA-M68MT-S2 motherboard, which was lying unused with a friend. Just as a project, I want try and build the most powerful system possible using this as a base. This is only a hobby project, so suggestions to upgrade the board and overall system isn't what I'm looking for. I'll probably just experiment to see what games I can run at max or high settings. I'll be using Windows.

\n\n

What I'd like to know is: What's the highest CPU and GPU this can take? I believe the Phenom II x6 (Socket AM3) is supported. What GPU will not be bottle necked by this relatively old base config? Since the on-board GPU is an NVIDIA\u00ae GeForce 7025/nForce 630a chipset, can I go for an 8- or 9- series? Is a Radeon a better choice?

\n\n

I haven't been a PC gamer for over a decade, but I'm keen on getting back into it.

\n", "Title": "What's a good PC config based on an AM3 motherboard that won't be bottlenecked?", "Tags": "|gaming|graphics-cards|processor|motherboard|windows|", "Answer": "

The best answer here is to put into this what it is worth - which is basically a low-end gaming system by today's standards. Dropping one of the hexacore CPUs into this will likely represent an investment simply not worth the returns, since those CPUs are highly sought after now that they are out of production and command a high price on a resale circuit - so much so that newer, cheaper chips from AMD and Intel beat them out.

\n\n

However, given that the above is not actually the ANSWER to your question, the ANSWER lies on the CPU support page for your mobo's revision level: the most powerful processor available to you is the Phenom II X6 1090T. The AMD Phenom II X6 1100T May also work, but it is not officially supported by the BIOS, so I can't say definitively that it will work. It will probably work. Be careful, because there are Phenoms made which exceed the TDP rating for your board and could easily damage it.

\n\n

What GPU will be bottlenecked/not bottlenecked by this CPU? All of them; that's not how bottlenecking works. Different programs place different strains on different parts of a computer, so even a high end CPU can be the bottleneck of a low-end GPU if it is trying to do something like downscale an h.265 video transcode, which is highly CPU-intensive, or play a game like Civilization 5, which is notorious for its high CPU usage in the late game but places relatively low demands on GPUs.

\n\n

Because the CPUs available to this board are somewhat weak compared to modern offerings in a similar price bracket, it makes sense to get an Nvidia GeForce GPU instead of an AMD Radeon GPU, because historically Nvidia driver overhead (the load placed on the CPU when the GPU is running) has been higher for AMD products. This is not a major consideration, however, so price is a major determinant.

\n\n

The onboard GPU is of no consequence for your purposes unless you want to attach a second screen to it; then it would make a little more sense to go with Nvidia for your primary GPU just so you could have a driver environment all from one supplier, which should be a little more stable (not necessarily though, since you will need to run two separate drivers and that old motherboard GPU may not have Windows 10 compliant drivers).

\n\n

With a 1090T CPU and a decent overclock to something like 4ghz on all six cores, given a Titan X GPU (not a recommendation, just a removal of most GPU bottlenecks for hypothetical purposes); this system should be able to handle most modern games at maximum settings; a notable exception would be any title which is heavily single-threaded and demanding on the CPU (most bad console ports, for example, of which Assassin's Creed: Black Flag and Unity are shining examples). In general, the CPU is less a limiting factor in gaming PCs than the GPU. Tests have been done showing the lowly Athlon 5350 performing admirably when paired with a midrange modern GPU. Where you are comfortable in that gradient of performance is largely up to personal taste.

In this question I received the response to which graphics model should I go with. Now, as I started calculating using this decibel calculator, the fact that I am trying to buy quiet 8.9 dB fans (total = 20.9 dB) will be negligable if a graphics card will generate 36 dB (which is what I found here) - than the total noise will be 37.081 dB.\nHowever, on Tomshardware I found this to be more nuanced, but also incomplete (no MSI card).

\n\n

What graphics card manufacturer would you recommend for GTX960 noise-wise, provided the price differences are negligible? Or maybe there are other considerations under 250$ for gaming setup (i5-6500, 8GB ram, 240GB SDD, 4 140mm fans, MSI170 pro gaming mobo, 1280 x 1024 res) that are significantly quieter?

\n\n

[EDIT]\nI am aware of 'silent mode', where fans turn off on idle, which is apparently implemented by all manufacturers in GTX 960 (source). The question is about the fan noise under load.

\n", "Title": "Graphics card with quiet fans", "Tags": "|gaming|graphics-cards|quiet-computing|", "Answer": "

While this may not be the best solution depending on your case airflow, the Arctic Accelero S3 may interest you. Passive cooling is more common on server components, but the Accelero S3 is a GPU heatsink that can support 135W TDP, or 200W with its \"Turbo Module\" (but it's just a fan, which rather defeats the purpose of the heatsink). While the Twin Frozr V is very quiet, it can't really beat not having fans at all. With good case airflow, the temperature is significantly higher, but not worryingly so.

\n\n

Why you may not want this:

\n\n
    \n
  1. It costs $55 dollars, which, while still being under budget if you pick one of the cheaper 960s to mod, this is a pretty hefty investment.
  2. \n
  3. Other fans have to work harder, so the gains may not be obvious
  4. \n
  5. This will probably void your warranty
  6. \n
  7. It doesn't eliminate coil whine
  8. \n
\n\n

So, why would you want this?

\n\n

If you're serious about wanting a silent PC, and have already chosen a soundproofed case, quiet fans and a good CPU cooler, this is a good option. Otherwise, don't bother, there are easier and cheaper ways of quieting your PC.

Depending on your needs I've added a few various cameras. All are great choices and meet the specifications the question provided, but it's up to you to decide which one you think fits your needs best.

\n\n
\n\n

Sony Action Cam - $115 - $198

\n\n

I'd recommend Sony's Action Cam line up.

\n\n

\"Sony

\n\n

Sony's Action Cam offers a wide variety of features, a quality build, and all at a reasonable price.

\n\n

Sony offers a wide variety of their Action Cams, but I'll be recommending the AS2000V. The Sony \"Action Cam\"s can take 1080p @60fps and great 8.8MP photos. It supports 240fps slow-mo, and a great microphone. It supports 60m waterproof. It also has video stabilization with SteadyShot which I've heard great things about.

\n\n

Alternatives

\n\n

I highly recommend you take a look at the wide variety of Action Cams, these don't get too expensive and offer many features. An example is the Sony AS15 which is only $128 on Amazon and offers a similar set of features. Also, be on the lookout for discounts as these frequently go on sale.

\n\n
\n

This camera has a lot to offer with it's wide variety of features making it a great choice if you'll be doing some shaky video, low-light filming, or for general use.

\n
\n\n

GoPro, $129 - $199

\n\n

The popular GoPro is a popular choice for a sports and action camera. While price ranges, GoPros have a wide range of accessories and mounts to choose from.

\n\n

The GoPro I'd recommend is the GoPro Hero ~$129. If you want, a WiFi equipped model which also offers slightly better specs, it's starts at $199

\n\n

\"GoPro

\n\n

The GoPro Hero can take 1080p @30fps (60 WiFi model) video, photos can be taken at 5MP (8MP WiFi model), and supports up to a 32GB MicroSD. It's also waterproof up to 40 meters.

\n\n

Alternatives

\n\n

I've already talked about the HERO with WiFi but the HERO4 Session also the same specs as the HERO with WiFi at the same price. The HERO4 though has a much simpler design, which can work great for hobby use but may lack functionality for power-users.

\n\n
\n

I'd recommend the GoPro if you'll take advantage of it's wide-array of mounts and accessories

\n
\n\n

ISAW, $100 - $189

\n\n

The ISAW EDGE ~$189 seems to be a perfect fit.

\n\n

\"ISAW

\n\n

The ISAW EDGE can take 1080p @60fps, and even 4K. It can take up to a 64GB Micro SD card and can take 16MP stills. It features underwater capabilities up to 40m.

\n\n

Alternatives

\n\n

The ISAW Air runs at 1080p @30fps, takes 12MP photos but requires a case for waterproof (~$25)

\n\n

The ISAW WING runs at 1080p @30fps, takes 12MP photos and features a 40m waterproof housing.

\n

The ISAW offers well balanced specs at a reasonable price, it has a relatively easy-to-use graphical interface.

It seems obvious the \"best\" setup would be a Mac Pro (currently $2999+ without a display). But with a not-for-profit budget, if I don't have to spend $4000 for a complete setup I'd rather not.

Would FCPX used as I describe above on these specs of an iMac make for a lot of waiting on the system while editing? Should I be looking at something different in hardware?

\n", "Title": "Final Cut Pro X: iMac or Mac Pro for House of Worship?", "Tags": "|video|osx|video-editing|", "Answer": "

The RAM is probably the main change I would make to your proposed specs.

\n\n

Narrowing Down the Options

\n\n

If you're going to want an iMac, especially for video editing, you're going to need a fast hard-disk, enough RAM, and definitely a good GPU. This immediately narrows down the selection to a 27-in 5K iMac. Why? The 5K iMacs are the only ones offering discrete graphics. The 21\" iMac offers only a 5400RPM hard disk which is much too slow for video-editing.

\n\n

The Optimal Specs

\n\n

I'm going to assume you're editing 1080p video. 1080p video directly out of a camera can is around 300MP, for 10 minutes. OS X tend to use around ~4GB for the system, running Final Cut, live streaming video, and handling audio, 8GB might run out quickly. At the least 16GB what I'd say is the minimum RAM for your case. 32GB would be best.

\n\n

What I'd Recommend

\n\n

I'm going to recommend the 27\" 5K iMac with:

\n\n\n\n

With 16GB of RAM, this comes out to $1,969.00, and with 32GB $2,329.00

\n\n

Alternative RAM Option

\n\n

If you're comfortable with manually upgrading the RAM (yes, 27\" 5K iMac has user-upgradable RAM). You can purchase an 8GB model and use a OWC RAM upgrade kit (only $129-$249).

\n\n

This brings your total price for a 16GB to $1,918 and for 32GB to $2,038

The 840 EVO and 850 EVO are both consumer TLC SSDs by Samsung. The EVO series doesn't exactly have any differentiation, and the 850 EVO is not the higher end model, rather, it is the newer generation. The reason that the 840 EVO has risen in price is most likely because it's an retired series and therefore no longer manufactured in volume.

\n\n

The chief differences between the two SSDs are in the NAND and controller. The inclusion of 3D V-NAND improves performance and write endurance, while the downgrade of the controller to two cores would decrease it. The overall effect in the wild would appear to be a moderate increase in write and mixed IO speed, with a more minor increase in read speed and a minor decrease in deep queue read speed. Overall, read and random mixed IO would probably play the major role in normal desktop operation, You should get no advantages with the older 840 EVO.

I don't have a TV because I think they are ugly and require too much space. I like the idea of packing away the screen so it's not always there, in plain sight. However I still like to watch films, so I often just watch films on my laptop. I have an old projector, which I bought to watch films with. However I found the fan too loud, and I found it annoying to set up, Requiring many cables to power the projector, my laptop and the HiFi system. It takes a long time to turn on and then to turn off which was also annoying.

\n\n

Recently I have come across two devices, that have the potential to solve some of these problems and are not too expensive.

\n\n
    \n
  1. The ZTE SPro2 is primarily a projector but has a battery and android built in. It has 200 lumens and a high res screen, but when on battery it will only run at 100 lumens. It is difficult to source in the UK and I would have to buy it on ebay as an import. If it does not work as I expect, it will be hassle to return.
  2. \n
  3. The Yoga tab 3 Pro this is primarily a tablet but has a built in projector. The projector is only 50 lumens and 480p resolution projector, but the battery life is much better. I could probably watch 2 films on one charge. The main advantage is, that it's an ok tablet as well, which I might end up using a fair bit, although it's not something I really need or want (I wouldn't just buy an ipad for example). I can source this easily through amazon uk.
  4. \n
\n\n

So to sum up I am looking for a device for occasional film watching that is nice and clean and which can be packed away when not in use.

\n\n

My living room is quite bright, so I think for both devices it would work better in the winter. Has anyone had any experience comparing the brightness of the devices in real life? What do people think?

I\u2019ve been asked to install a new monitor in an EMS (Ambulance) station. The monitor is by the garage doors, and needs to mirror another monitor connected to a computer on the other side of the garage. This is a volunteer EMS group, so the budget is limited. I\u2019d rather not buy a new graphics card, but it\u2019s not out of the question.

\n\n

We\u2019ve measured the cable run at roughly 55ft (17m).

\n\n

The monitor we need to mirror is connected by DVI.

\n\n

There\u2019s a second monitor also connected via VGA.

\n\n

The computer has no third monitor port; it has just 1 VGA port and 1 DVI-D port. It\u2019s a cheapish old Dell. The sole use for the computer is showing currently active calls, and the people who\u2019ve paged in to take them.

\n\n

What\u2019s the best solution to setup display mirroring on the new monitor? No kb/mouse is required at that distance. This is view only. To be clear, the monitor is already mounted. Just need to know the best way to get the signal to it, given the constraints I have.

\n\n

I\u2019ve taken a look at kits: I can get either DVI or VGA splitters, and 20M cables for both.

\n\n

Are these options decent, or would I need a powered splitter? Bear in mind, that\u2019s $10 vs $150 it seems.

\n\n

Which is preferable over longer lengths? VGA or DVI?

\n", "Title": "Long distance monitor connection options?", "Tags": "|dvi|vga|", "Answer": "

Another option, for even longer distances, is a KVM over CAT5 extender. Startech has many options, among other vendors. I'd search on Amazon as the prices are generally better than buying directly from Startech.

\n\n

For example, the SV565UTP (they are sold in pairs):

\n\n

\"enter

\n\n

You take one and put it next to the computer and connect it to the machine's keyboard, mouse, and monitor outputs. You take the other one and plug a keyboard, mouse, and monitor into it. Then you run a CAT5 cable between them and you get up to 500 feet.

\n\n

They make longer distance ones; there's a 650 ft VGA/USB extender, there's a whopping 1500 ft DVI/USB extender, and so on.

\n\n

These are overkill for your 55 ft in terms of cost, but if you need even longer runs, or you have the budget, they're a good option. It's a lot easier to run CAT5 through walls and such than VGA / DVI, too, and cheaper to replace failed cables (or re-terminated failed connectors). If the building already has CAT5 wiring for ethernet you may be able to repurpose one of the existing runs. If you already have a network closet with a patch bay for wall jacks around the building, it also makes moving your console around in the future pretty trivial.

It depends on a couple of factors:

In general, yes, an SSD and more memory will speed up VMs. For me, switching to SSD provided a greater performance benefit than any other single upgrade I've ever done.

\n\n

If your MacBook already has SSD, a newer/bigger/faster SSD isn't going to make much difference.

\n\n

RAM will only make a difference if it gets used, which depends entirely on how much you have, how much is allocated to the VMs, what operating systems they will have, and what programs you run in the VMs. 4 GB sounds like not much RAM to be using VMs, especially if you're trying to run more than one at a time.

I am going to upgrade my PC over Christmas, and right now I'm trying to pick out a PSU. I would like it to be fully modular, 80+ gold or better efficiency and preferably cheap.

However, now I'm wondering if it has too many watts. My maximum estimated wattage is 457, and the Antec PSU goes up to 750.

Are there any downsides that I'm unaware of to having significantly more power in your PSU than your pc will actually draw?

For a 80-Plus Platinum power supply, efficiencies are between around 5% of one another between the 20 to 100% range of load(88-92, give or take a percent). It tops at around 70% load. \nHaving more than required is certainly not a bad thing. PSU's like the HCP are rated to deliver their full wattage at fairly high temperatures, and 300W is enough for any card.

\n", "Title": "SSD / HDD choice when write speed is slow - developer workstation and for games", "Tags": "|gaming|hard-disk|ssd|", "Answer": "

SSDs should never be slower than a HDD, especially in small files. The reason is because of how they work. A HDD uses a spinning platter and a read/write head for information access where a SSD uses a controller with flash chips. When reading/writing files, the HDD has to wait for the head to align with the platter before it can be accessed, but a SSD doesn't have to wait.

\n\n

In my experience I would only recommend a Sandisk SSD for their reliability, and nothing else. Write speeds are usually less important than read speeds, because if you think about it, you are mostly doing reading of files rather than writing of files. The Samsung SSD will provide significant improvement over the Sandisk ones so I would recommend the Samsung one. You can also look into SSDs from other manufacturers that can be cheaper without sacrificing much performance, such as A-Data, Kingston or Crucial.

\n", "Title": "Motherboard: Which configurations really matter?", "Tags": "|motherboard|", "Answer": "

There are many chipsets with the LGA 1151 socket, including the Z170, B150, H170 etc. The only chipset that allows overclocking would be the Z170 chipset, which you should get since you are getting a overclockable CPU. The other chipsets I mentioned are cheaper (sub $100 range) but lack some of the features the Z170 has. Even with the same chipset, there are higher quality motherboards (more expensive) and lower quality motherboard (cheaper). The higher quality motherboards have more features such as better power delivery to allow more overclocking, better NICs, better sound cards, more PCIe slots, etc. The motherboard you would need would depend on what you are using it for.

\n\n

A $60 motherboard would be \"good enough\" for you. You would not be able to overclock if it's not a Z170 chipset (so the overclockability of your CPU is wasted), it probably doesn't have SLI and/or CrossFireX support, so you would be limited to only having one GPU. The PCIe lanes could also be slower, so higher bandwidth PCIe cards would take a performance hit.

\n\n

The speed of the RAM doesn't have to correspond to the motherboard's rated max speed. The RAM would run at the lower speed of the two (e.g. if your RAM was 3000MHz and your board only supports max of 2400MHz, it would run at the lower of the two, which would be 2400MHz). This also means you are wasting some of the power of the RAM if you buy a lower end board. You would also want to check with your motherboard manufacturer's manual to check if the RAM is compatible with your board.

However, I can live with a card that has some features disabled in Linux, as long as basic playback and recording works, I don't have to install any proprietary drivers, it works reliably, and is hassle-free (i.e. no configuration to get regular sound working, and none of that \"has to boot in Windows first before it works in Linux\").

I just got the Phantom NZXT case (specs) for my PC. It works great for me, but this thing is so huge it barely fits in my desk! Now, it does fit, but since the 1/8 in audio output and USB ports are on the top, I can't plug in any of the USB ports or my headphones. Since this thing has 5 drive bays on the front, I'd like to get a USB drive bay with a 1/8 in output for my headphones. I can find plenty USB bays on google, but none of them include an headphone port. If I search for "USB bay with aux" I get a bunch of links to amplifiers, which are clearly not what I'm looking for. Does this even exist?

Just about any front panel audio will work for you. I merely searched for \"audio 5.25\" and found this product for $14 (customs and VAT may apply). It fulfills exactly your requirements and nothing more. It's also worth noting it's \"HD audio\" - that's the most recent spec of connecting audio jacks to mainboard (the part that makes your computer detect plugging of jacks and let you decide in software what function will it perform).

\n\n

However if you're really after simply replicating AUX jack from the back of your computer, then products like this archaeological artifact are surprisingly still available. The point is visible on the last pic: those cables doesn't even connect to internal mainboard ports at all! They're just \"dumb\" male jack to female jack extension cords. If you have such special needs, they will trick your computer into thinking that something is always plugged in, even if there is nothing attached to the front panel. Fun fact: it will even work just as well on the desk, outside of your computer.

\n\n

Side note: as your case has bay door that will block access to front panels, maybe regular extension cords: a pair for headphones/mic and another for USB, plugged into back will serve your purposes better?

\n\n

Yet another thought: many monitors have USB hubs and audio out (from HDMI) jack. There is a slight possibility you already have everything you need : )

My mouse was broken a few days ago, so I need to buy a new mouse.

\n\n

I am interested in a trackball or vertical mouse because professional writers say that is better for my hands and that it's a good alternative to a normal mouse.

\n\n

I don't want to spend too much money, so I am planning to buy one of the following two products:

\n\n\n\n

I usually do web surfing, and I sometimes work on office suite programs. Sometimes I do a little coding and rarely play games like Minecraft.

I would like to have recommendations about the above two products, and if you have any alternative products that you think are better than those two, please let me know.

\n", "Title": "Can I have recommendations about the trackball / mouse?", "Tags": "|mice|trackball|", "Answer": "

Vertical mouse is OK only if you never take your dominant hand off the mouse. Regular users tend to keep moving their hand between mouse and keyboard. Vertical mouse is very bad for this as it takes extra time and effort to both let it go and grab back again. Trackballs are bit better, but if you do follow the common click-click-type-type-click-clik pattern then regular mouse is the best.

\n\n

The exercise of moving your hand back and forth between mouse and keyboard already is the best thing for your health. Super-ergonomic mice solve a problem that you don't have.

\n\n

I recommend that you buy regular mouse (eg Logitech RX250, around $15). To be blunt: for regular users regular stuff usually works best : ) Consider better mouse when you have the money to burn.

\n\n

If you insist on buying one of the mentioned products then check out customer rights in your (and store) jurisdiction. In many places you are entitled to return a product bought online after a short time simply because you don't like it. This is exactly the situation lawmakers had in mind. Yet, I think you really should buy a decent, entry-level mouse first. At least as a backup plan.

So I'm looking to buy a new desktop computer and I'm getting a little confused, my main concern is that it will be able to play the sim3 with multiple expansions. I found a computer that seems like it will work and can have the i5 processor vs the i3. I'm just very confused about which processor will be best.

\n\n

these are the specifications of the computer:

\n\n\n\n

I'm getting confused because most comparisons I do say the i5 is better for gaming. However the i3 is much faster 3.7 GHz vs 2.7GHz(3.3 turbo) and most things I read about sims recommendations is that the the faster the processor the better. \nThe i3 build is about 100 dollars cheaper as well, so I don't want to waste money on the i5 if the i3 is actually better for my needs.

\n\n

I'm just looking for a good base computer that I can play some sims on that I can upgrade as I go. I don't really mind playing it on low settings, I just want to be able to play all my expansions I have about 5 expansions and on my current set up I can only play 2 expansions without horrible lag times.

\n\n

So would the i3 or the i5 be better? I really don't understand the differences.

\n", "Title": "i5-6400 vs i3-4170 for playing sims 3", "Tags": "|gaming|processor|desktop|", "Answer": "
\n

I just want to be able to play all my expansions I have about 5 expansions and on my current set up I can only play 2 expansions without horrible lag times.

\n
\n

The recommendation could be better if you include the specifications of the computer that has the lags in your question, so we can analyze where the bottleneck in your current setup is and if the newer hardware would be a substantial improvement.

\n

That being said, The Sims 3 was released in 2009, is based on DirectX 9 and has moderate hardware requirements. A fairly obvious case one might say?

\n

Core i3-4170 vs. Core i5-6400 GPU

\n

For comparison of Intel GPUs there is a separate article in Wikipedia that gives a really useful overview, combined with the data in the lists for all the Intel processors (list-type Wikipedia links are/were banned on some SE sites, but they are not hard to find) we get this:

\n\n

So just by looking at the GFLOPS, there isn't really any difference between both models but about 30% increase over the older generation.

\n

DirectX 9 in 2015 how hard could it be?

\n

Just for a test I ran Tomb Raider (2013, DirectX 11) on the laptops GPU. By lowering the graphics settings I was able to play, but I am much less finicky about lags. With that in mind I thought DOA5:LR based on DirectX 9 in 2015 released on PC would run smooth, but I was wrong. I wouldn't wave off GPU demands so easily anymore. Chances that Sims 3 will run fine however are pretty good, especially when looking at this section from the recommendations:

\n
\n

For computers using built-in graphics chipsets under Windows, the game requires at least:

\n
Intel Integrated Chipset, GMA 3-Series or above\n2.6 GHz Pentium D CPU, or 1.8 GHz Core 2 Duo, or equivalent\n0.5 GB additional RAM\n
\n
\n

Both of your options outperform these requirements, but it's hard to tell which level of detail can be achieved and it doesn't look like there is enough headroom for newer games like Sims 4. If I was a Sims fan and had to buy a new computer today to play Sims 3, I'd make sure that it would also run Sims 4 from 2014, which is still based on DirectX 9, has moderate requirements for 2014, but is much more demanding in terms of GPU power. DOA5:LR is still a different game, but let's say I have doubts when I read the following in the minimal requirements:

\n
\n

GeForce 6600 or better, ATI Radeon X1300 or better, Intel GMA X4500 or better

\n
\n

If you still want to go APU only for Sims 3, then it's fine, for Sims 4 I would consider looking at AMD's APU offerings in similar price ranges. They are not very competitive compared to Intel's high performance offerings and their latest desktop CPUs are from 2014, but their iGPUs are said to have significantly more power (1, 2) and the CPU part still manages to run games too.

\n

Upgrading CPUs

\n

I think Piotr is wrong when he says:

\n
\n

That way, in years to come, the i7-6700 processor can be much cheaper, not to mention other processors that will come for this chipset (Cannonlake and Kaby Lake).

\n
\n

I would like to see more facts, preferably in the market where you are/the OP is. My experience here in Europe/Germany is that prices for Intel processors are very stable after the spike at launch and opportunities for a bargain offer are minimal if you want to avoid buying used hardware (from users where you don't know how they treat their hardware).

\n

Also buying any board with a Skylake compatible chipset appears more like a bad idea when you look at how many products a chipset family has today and how quickly Intel changed sockets in the last years or which features were missing and were only added to the next generation (no native USB 3.0 for example, and it looks like Skylake and Kaby Lake will have the same thing for 3.1). By now it should be very clear to everyone that Intel is releasing features successively and moving from a tick-tock to a tick-tick-tock model or something different. At any point you will not get the full feature set to be future-proof until the next better thing appears on a roadmap. This is pretty disappointing for long time upgrade strategies, but Intel can relax when it comes to selling single processors currently, they have to focus on marketing entire platforms (all devices where you don't usually upgrade the CPU) and to be fair platforms have increased in complexity so it's not only ill will that we can't go back to the good old Socket 478 or earlier days.

Since you got a overclockable CPU, if you want to overclock in the future you can do that with this cooler no problem. The new Skylake CPUs have a thinner PCB, so heavy CPU coolers can actually bend the chip (not a good thing).

I really can't think of a reason to get cold cathodes, except maybe they produce more light than some LEDs. LEDs will always use less power as long as you are comparing it against a cold cathode with the same amount of light emitted. LEDs will also last longer than cold cathodes and are less fragile since they aren't in glass tubes. LEDs usually come in strips, so it is bendable which means that you can bend it around your case to get adequate lighting. Cold cathodes also require a inverter that converts your DC power to AC power, which is another source of inefficiency and point of failure. For looks, LEDs will look better because they are flexible but cold cathodes will give you a much more retro look.

I have used Devolo dLAN 200AVs extensively in my UK home for about five years now, and they are great.

\n\n

\"Devolo

\n\n

I have about six of them, all single Ethernet port (multiport versions, which three Ethernet ports, are available). I have not found this to be a problem, because I have switches/hubs in most rooms, anyway.

\n\n

They have UK plugs, not US plugs, but none of my dLAN 200 AV devices are pass though (i.e. you can plug a mains device into them), so I needed either use an extension cable with a 4 or 6 way plug board attached, or where I had dual sockets in the wall, I just sacrificed an outlet.

\n\n

The benefit of pass through devices, is that they contain noise suppression circuitry inside them, to help counter any noisy devices, or power on spikes that may be generated by adjacent devices that may also be plugged in to the plug boards. Devolo actually recommend that the dLANs are not plugged in to plug boards, and that they should only be plugged in at the wall, due to signal degradation. However, I personally, have not experienced many problems, mine all work fine.

\n\n

I recently added two 500 dLAN AV Plus devices, which do have pass through.

I use these for a higher speed connection from my media server, in my garage, to my lounge, where the XBMC is, and I can stream videos just fine. They also are compatible with the existing 200AVs, so now every room is connected.

They even come with a remote admin tool, the dLAN Cockpit, that works on OS X (as well as WinTel machines). Also available are Wi-Fi extenders, which act in the same way as the Ethernet variants, but pump out Wi-Fi instead.

\n\n

Also, the wiring in my house is about 50 years old, and no problems have arisen because of that. They can get quite warm, but even after having them plugged in for 4 years solidly, that has not been an issue.

I can not recommend these highly enough.

Also, I purchased all of them, secondhand, on eBay for around \u00a310 each for the 200AVs and \u00a320 for the 500s. Just wait for someone selling a bulk lot because they are upgrading (i.e. from 200 to 500, so they are selling off the 200s cheaply).

I'm in need for a new screen. I've started looking for some screens but then I came the question: 21:9 or 1440p? After some digging around if found 2 screens i really like.

\n\n

One from Lg that is 21:9 1080P and Freesync support(not that i can use it but more on that). The other screen I found was Dell ultrasharp 1440P screen. Which of the 2 is better for gaming and light programming. I will also be running a second 1080p screen of an 21\" size format.

\n\n

The LG 29UM67 is a 1080P 21:9 screen this means it gets a resolution of about 2560x1080. it has a 75Hz refresh rate in freesync mode which can be activated no matter what videocard you have on it. The format of the screen it 29\" so its not big nor small. Without freesync the screen may get screen tearing.

Depends on your working/gaming style I suppose.

\n\n

Maybe its cause I'm older but I tend to treasure vertical space over horizontal space, so ultrawide displays have never appealed to me. As a replacement for two monitors, or as part of a expansive stretched workspace 21:9 might work awesome. You can dock 2-4 windows and have plenty of space without the annoying bezel. Its a bit of a niche product and prices are adjusted upwards accordingly. That said, I'm not a fan of wide screens and this is a bit of a biased opinion

\n\n

On the other hand 1440p is pretty well regarded - Until recently Jeff Atwood swore by 1440p/27 inch displays that were pretty reasonably priced, and your dell is smaller - which means better pixel pitch. Text is likely going to be sharper, backlight bleed is not that bad on quality displays (and seems to be more of a thing on IPS displays, and for gaming, its a more common aspect ratio. I've driven games at 1440p- with a gforce 660, so it would also be easy to run for gaming

\n\n

Pixel pitch is a big deal. Basically the more pixels per square inch you have, the sharper a monitor is, and the easier it is to read text. I'm not too sure how much of an improvement it is between 1080p and 1440p, since I jumped straight to 2160p but it would likely be better to have higher resolutions

\n\n

As for aspect ratio 16:9 is the standard for TVs. Its standard for most games, and PC gamer seems to think you need additional software to get things running.

So, between them? The Dell makes more sense. I'd probably also consider a few less traditional options before making my choice tho

I'm looking for a NAS device for the purpose of running backups of several other machines. My current setup for this is a consumer PC with extra drives plugged in, but this is non-optimal for several reasons.

\n\n

I want NAS hardware because consumer PC hardware with enough disk slots usually comes in an enormous case and requires expensive motherboards and so forth. This system does not need high hardware performance, and ideally would cost less than $500. However, I intend to install a standard Linux distribution on it (probably Arch) and handle all software requirements myself. Thus, I need a system on which it is easy to boot from a CD or USB and install a new OS. (My prior research suggests that many NASs require fiddling with the hardware to achieve this; I'd prefer to avoid that.)

\n\n

I would like at least four disk slots, and would prefer that it came diskless. I will connect it via Ethernet, and do not require any other network hardware. As mentioned above, it will be used only for periodic backups of other machines, which have live data; thus, the hardware performance other than network and disk bandwidth is mostly immaterial. And of course, because I will handle the software myself, I do not care about what software package it comes with, only that I can get rid of it.

\n\n

Any recommendations?

\n\n

Edit: The usual OS install process requires a video output, which is apparently rare on NAS hardware; however, it should also be possible to install over the network (particularly a distribution such as Arch whose install procedure is from the command line itself). Thus, while it would be more difficult, a device without video whose bootloader can be edited or replaced would also suffice, so long as an unrestricted network shell is available from the original OS.

I will understand if this is off-topic, I couldn't really understand the rules, but I saw some similar questions. I'll delete this if you consider it to be off-topic.

\n\n

This is my current PC:

\n\n\n\n

My idea is to upgrade my computer so that it allows for further modification but in such a way that I don't get bottlenecks. The GPU is pretty new so I won't be changing it for now. I use my computer mostly for gaming and work (Visual Studio + Hyper-V with a Windows Server 2012 instance), and because of this an upgrade to 16GB RAM is needed (8GB runs short sometimes).

\n\n

These are the upgrade paths I've been able to identify which could provide me a nice performance gain for at least some time.

\n\n

Upgrade1 (current CPU is given as part of the price)
\nThis path has two downsides: RAM keeps being DDR3, so upgrade to DDR4 will be required in some time; and the FX8350 is basically the top of what AM3+ will get.

\n\n\n\n

Upgrade2 (current CPU and motherboard are given as part of the price)
\nThis path has the same RAM downside as Upgrade1.

\n\n\n\n

Upgrade3 (current CPU, RAM and motherboard are given as part of the price)
\nThis path allows for DDR4 RAM, many CPU upgrades if/when required and the motherboard has 2 PCI-E 3.0 slots for many different GPU setups, when an upgrade is required.

\n\n\n\n

What I'm wondering is if the Upgrade3 path is really worth the USD700 (without taking into account that the final price will be around USD450 upon giving my components). Also, I'm not from the USA, that's why prices will probably seem much higher than they should be (and importing is not an option).

\n", "Title": "Deciding on PC upgrade path", "Tags": "|processor|memory|", "Answer": "

For your computer, besides the extra RAM you need, I recommend an upgrade to your CPU cooler (something like the CoolerMaster V6 would be very nice) so you can overclock your current CPU. While the FX 4350 is only a two module CPU, it should handle most tasks well, and applications requiring more than 4 threads are rare. Only when you feel that your CPU is performing inadequately even with an overclock should you upgrade. If more cores will help, a AMD FX 8320 will perform just as well as an 8350 when lightly overclocked. If you need single threaded performance, you will need to go with Intel.

\n\n

For Intel, since you can't find a K series CPU, there isn't much point getting a Z series chipset. A H97 or B85 would do just as well. Skylake doesn't really offer much in terms of increased performance. Unless you need the features of the newer platform, my advice would be to stick with Haswell.

I'm looking for a desktop which runs recent games at medium to high settings and costs about 600$. The specs should be like something along the lines of the following:

\n\n

CPU: 3GHz Quad Core
\nGPU: 1GHz
\nVRAM: 2GB
\nRAM: 8GB
\nDISK: 500GB+

Furthermore, since I don't want to spend too much money on power, I would like it to be quite efficient, preferably with a wattage lower than 250/300W if this is possible, given my other requirements. I found this excellent 600$ build online but the wattage was far too high (400W-ish). Any suggestions?

So u don't actually need a lot of processing power. The trick is to understand what you will be using most. Mysql usually only runs on 1 thread, same as SSH. I seriously doubt u will stress the Pentium CPU. if you need more power then you should consider some other alternative.

Thats just my 2 cents.

The mother board does not have IPMI!

if you want to be able to control the board without a monitor or keyboard you will need IPMI (when SSH is offline. Ex: when you are in BIOS or something like that).

I bought a Razer Tiamat 7.1 headset. I was a bit silly though and thought the USB that connect the headset to the computer was not just to power the headset. I'm using a laptop and it obviously doesn't have a 7.1 sound card. It does come with female 3.5mm jacks to micro USB, but those are meant for connecting other speakers through the control unit of the headphones. Maybe there is a way to hack it so it uses it to connect the headphones to the laptop's USB instead, but I doubt so...

\n\n

So are their any decent solutions for going from 7.1 3.5mm jacks to USB or HDMI? Also I don't want to spend more than $50 on a solution for this. Otherwise I guess I'll be destined to use it in 2.1 mode until I upgrade to a desktop.

\n", "Title": "USB 7.1 sound card, or converter", "Tags": "|usb|hdmi|sound-cards|", "Answer": "

I'd say it's not worth spending more money to get more performance out of this or any other 7.1 headset. Just use it in stereo mode if you have no 7.1 source.

\n\n

Operating systems and applications like games or media players are responsible for handling sound: selecting the appropriate output path and channel profiles, applying dynamic range compression where necessary and so forth. This is particularly true for games where the soundscape is rendered by the game engine and it doesn't get more accurate with 2 speakers or headphones than the game engine knowing that it should render a stereo signal. A multichannel downmix by an unknown element in the chain doesn't improve the result it's just a dishonest, technophobe marketing myth and number game that is still around.

\n\n

\"enter

\n\n

Stereo (1), generated Downmix (2) and 5.1 Mix (3-8) of Paschendale from Iron Maiden (Sources: 24-Bit FLAC, DVD-A)

\n\n

If you need a visual example, download Audacity or any other audio editor, load a multitrack audio track from a movie or audio recording and mix it down to stereo. Many people pretend to care much about clean audio. Does the downmix with information from all channels look cleaner or more detailed to you? No, it doesn't! Good games are able to mix all the information into a high quality stereo signal. With the rise of VR binaural audio will get more important and virtual 7.1 mixes will hamper your immersion. Please let game engines do their work without interference, the game designers who put them together should know better how to treat audio that they or their customers create.

\n\n

I could suggest to you to get a cheap 7.1 USB soundcard from China, but that's worse than your built-in sound solution. A multichannel audio production interface can actually deliver good quality but is at least three times out of your budget, not very portable and the Windows drivers don't support running the channels as a 7.1 configuration for gaming while the hardware is capable of doing so. I'd rather recommend an O2+ODAC or a similar product and reference headphones if you're already willing to spend +150 USD.

I don't think you need a better motherboard. It doesn't affect performance when not overclocked. Even if the best PCIe slot is only 8x it's good enough for the GTX 970.

\n\n

As of RAM I would personally add another 8 GB. I would go with the same DIMMs, but if you need new ones I recommend the Crucial Ballistics series. The DIMMs are cheap and have good performance and I never had mine fail before. With the extra RAM it can help get a smoother timeline for 1080P editing and photoshopping. As for gaming power 8GB should be enough.

\n\n

Definitely go for an SSD as it's a cheap way to almost always get a performance gain. I would personally go with an Samsung or Intel SSD. As for Samsung I can recommend the 850 EVO and Pro, and as for Intel, a 730 series SSD should be good. I would get 2 SSDs in my opinion though, or one large one as I would store my unedited video and primary games on it.

By the way, just a handy tip. If you are serious about the video and photo editing it's handy to get a 10 bit screen with high color accuracy.

I'm a serious gamer and I'm looking at high end graphics cards.

\n\n

I know that the new R9 Fury (and Fury X) feature HBM which is supposedly good for 4K gaming. I currently use 4 1080p monitors connected to my desktop.

\n\n

Is there an advantage to picking the Fury cards over, say, a GTX 980? Especially given that I do not game at 4K, but I do use several monitors.

\n\n

Furthermore, I currently have a Gigabyte GTX 970, will I see any significant performance boost?

\n", "Title": "Breakdown of new AMD Fury Cards vs Top NVidia Cards", "Tags": "|gaming|graphics-cards|desktop|pc|", "Answer": "

If you upgrade to the R9 Nano, Fury X, or 980, you will see a definite increase in performance over your GTX 970. However, because you do not play games at 4k and the difference sits between 12-25%, I would wait on either the new NVidia or AMD cards to come out later this ear, and buy those.

\n\n

After the recent price drop, the r9 nano sits at the same price as the GTX 980 ($500 U.S.) and is more powerful, so if you really do want to upgrade, buy the Nano at that price point.

\n\n

Upgrading further, and you'll see that the 980ti is a better deal than the Fury X at it's price point of $650 U.S, and performs about 10-15% better in most games as well.

\n\n

Your upgrade also should depend on the kind of work or games you play. If, for example, you do video editing on your computer, I think the upgrade might be a good idea. But if you're just upset with having to tune your settings to high instead of ultra to play at 60fps... I would wait.

\n\n

Keep in mind that in some games, especially games that use NVidia Gameworks like the Witcher 3, the 970 and 980 will perform better than the r9 nano, but in others, such at Grand Theft Auto 5, the opposite is true.

\n\n

All in all, I would just choose to wait until the new cards come out before upgrading, unless your job requires something more powerful or you have tons of cash lying around.

\n\n

Just a side note, two 970's in SLI perform very similar to a 980ti, and you will probably save money going this route as well, but doing this will reduce your computer's upgrade ability, and some games and programs do not support SLI, leaving you with the power of only a single 970.

The reason for $30 extra for ITX is because it is smaller physically. You are paying for higher precision engineering (same stuff needs to fit into a smaller square) also explains less PCI and RAM ports. The ITX board will also in theory use a bit less power.

The ITX board also has a TPM header the other one doesnt.

I am an experienced programmer with very little hardware experience, and completely overwhelmed with the unlimited number of choices available. Since technology changes so rapidly, it's very difficult to Google up a guide that is both timely and relevant for what I'd like to do.

\n\n

The best blog I've seen so far is this one, but it's already a few years old now.

\n\n

I currently have several KVM/VirtualBox VMs on my Debian laptop. It is extremely slow, and I can't run more than 1 VM at a time (or 2 with the second having a very small memory/processor footprint).

\n\n

I'd like to replace my laptop with a tower-based server for running these VM images, so I can remote in from any device on my LAN. My line of thinking is that I can get a lot more power into a larger enclosure for less money than an equivalent laptop would cost, with the possibility of upgrading down the line.

\n\n

Here's the basic idea of what I'd like:

\n\n\n\n

So it should be kind of like a \"home lab\", but mainly used for professional development work.

\n\n

I found some pre-built Lenovo servers on Amazon, and almost bought one, but I am second guessing myself in terms of what exactly to get.

\n\n

Where to start? Build or buy? How to get started picking the right components (e.g. motherboard, drive, processor)? I know my way around the inside of a computer... I can replace parts, etc., so building a server is not out of the question-- but unfortunately I don't know how to pick \"the best\" parts. My last few laptop picks have been flops.

\n\n

EDIT:

\n\n

Here's an example of a sample workload that I might want to have. As a personal interest, I might want to compile AOSP (android) in a Linux image. That eats up a lot of RAM and a lot of CPU. While that's happening, I'm working on professional windows development in a 2nd VM w/Visual Studio. It's not graphic intensive, but I'd be compiling regularly, which, employs parallelism. There would also a web server running in a third VM that would be serving REST requests for testing purposes, related to the development work.

\n\n

EDIT 2:

\n\n

I'm overwhemed with the massive amount of choice when it comes to hardware. I'd like some advice from experts on (a) whether it's better to build or buy pre-built, and (b) how to get started picking something that is a good quality build, and upgradeable in terms of RAM (and possibly CPU). What are good sources for getting this type of information? There is so much information out there, it's hard to tell what's reliable and what's misleading. I don't care if it's a pre-built server, or if it's DIY, so long as it is good quality.

I'd rather build than buy. It really depends on your needs though.

\n\n

If you're worried about noise, a home system actually makes a decent VM box.

\n\n

There's a few things I go for.

\n\n
    \n
  1. More cores. Get at least a quad core. For serious work a 'mainstream' core. I like a minimum of a quad core box - a core i7 is a decent workhorse machine, but both my recommendations are xeons. I typically run single core VMs

  2. \n
  3. At least 16 gigs of ram - the 'right' amount is enough ram for the host + enough ram for each VM. 8gb is a bit of a minimum I guess

  4. \n
  5. Enough storage. I favour SSDs for booting and speed reliant things - the samsung 850 pro 256gb is my preferred mainline SSD but the evo would work if you have the budget and want a 1tb SSD.

  6. \n
\n\n

For reliable storage, I prefer HGST - they have a nas line of deskstars I'd suggest taking a look at, though I have a pile of older, very trusty desktar models

\n\n
    \n
  1. No OS. Most of the good VM servers are free,
  2. \n
\n\n

If you're going to use this as a development box and want to run linux, fedora is a good bet. Excellent support for KVM and virt manager.

\n\n

If you're buying as opposed to building, a dell precison might be a good option. Old workplace had them and they were tanky, reliable beasts, and they fall within your price range.

\n\n

The 5000 series might be a good starting point - possibly the base model. I'd take a look at parts prices before adding any options since it may make sense to buy parts elsewhere to upgrade the ram and HDD. These things can go up to 8 cores if I remember correctly and are basically server grade parts set up as a desktop. I'm more familiar with the 7000 series, but those are for when you need two processors and is somewhat out of budget. Nonetheless, very solid machines, you're covered by the warranty, and if you're willing to spend a little extra, trivial to order what you need and know that it works

\n\n

Upgrades from the base model? Up the ram to 16gb, drop the OS (most of the good VM hosts are free anyway). Get a 3TB HGST deskstar drive. I'd be tempted to slot in an SSD for the OS (I would suggest a 256gb Samsung 850 pro) , but these things take a while to boot due to the raid controller.

\n\n

If you're building

\n\n

Might take a bit of tweaking to get it in your budget but a X10SDV-8C+-LN2F might be a good start Its ~1000usd but that gets you 8 cores. Load it up with 32gb (4x8, or 2x16) of ram at least of the cheapest standard DDR4 ram you can find. In theory, you can go up to 128 gb with Rdimms. Don't bother with ECC in this case, not really worth it.

\n\n

Its mini itx (so you can use a smaller case).

\n\n

Its somewhat limited in terms of video (VGA...) but also has IPMI (for out of band management, which is cool) and is designed for being a VM host, but at reasonable power consumption. Most of the xeon-d models are interesting, but this is the 'cheapest' one I could find with a fan.

USB ports are somewhat limited as well, and you have one pciex16, but that's more than you would on a laptop.

I have personally used this case in the past, and I can say that it does indeed work well. On a side note, the side panel is essentially one huge window; which means weekly cleaning (At least I did). Great case that can be had at Frys for $44

The HP EliteBook 820 G3 manual states that either a hard drive or a SSD might be installed (page 36). And not both at the same time. Thus, as-is, one can't install two SSD modules in that machine.

\n\n

The reason: apparently, the SSD connector is right there where the (SSD) SATA disk drive would be placed.

\n\n

I guess, if one really wants to install a 2nd SSD (in addition to the SSD that occupies the mSATA slot, cf. page 39) one could try following options:

\n\n\n\n

For both options, I need hardware recommendations.

\n\n

And perhaps some details, e.g. how the WWAN slot is actually called (mini PCIe?), what modules are compatible (mSata?) and how slim a module would have to be.

\n\n

Preferably, the SSD module should come from Intel or be of comparable quality.

\n\n
\n\n

Here is a combination of the drawings from page 36 and 39 of the manual showing the same drive bay for better visualization of the problem:

Edit: After understanding that the mSATA port will block the HDD drive bay I would suggest a Dual mSATA HDD adapter. Feedback is appreciated from anyone who is actively using such a setup as a boot drive on any OS.

\n\n

Edit 2016-04-17: I hoped that Skylake equipped business laptops (HP, Lenovo, Dell\u2026) would offer plenty of M.2 slots for SATA or NVMe storage, but the mobile chipsets don't offer as many PCIe lanes as the main or performance class desktop versions, which made some manufacturers come up with unexpected designs and decisions against a 2nd storage port or slot. Another example: Lenovo removed the small M.2 slot from the previous generation (T550) in favor of a combined 2.5 inch port where you can either install a SATA drive or a U.2 NVMe drive.

\n\n
\n\n

This is explained just a few pages below (p. 39) in the manual, it's an mSATA port. mSATA to SATA adapters exist, but are not suited for use in laptops. mSATA is replaced by NVMe in newer product generations, which achieves higher speeds by avoiding the SATA layer.

\n\n

Here is list of recent mSATA SSDs for Europe/UK with capacities starting from 120 GB. I currently have a Samsung 840 EVO 120 GB which works fine so far, but there may be options that suit your needs better. Once you nailed down the features you want, look if the products are available in your country and for which price.

\n\n

Guessing by your name you probably want to use the German version of the site for Austria and Germany.

Edit: the following video: https://www.youtube.com/watch?v=dF9gqAtM2U4 shows the installation of a second SSD in this model showing that it is possible.

I'm building a slim PC around a mini ITX motherboard, which should pack enough CUDA power with a low price. I came into the conclusion that GTX 750 Ti is a good choice (OK performance, low price, low heat generation).

However, the problem is that I don't know if the GPU will fit a specific motherboard with a specific CPU cooler and if the RAM modules will interfere.

You have multiple options in my opinion.

\n\n
    \n
  1. See if your shop offers this Laptop with a SSD.
    \nThis would be the easiest option for you probably
  2. \n
\n\n
\n\n
    \n
  1. Get a M.2 SSD - your laptop supports the new M.2 SSD's which are even faster than the regular SSD's. If a normal user really needs this is questionable but having the option is nice. It is more expensive though.
    \nIf you want to get a M.2 SSD you can get it here. Any of these should work - pick one which suits your budget and read some reviews when you have doubts.
    \nYou would have to add this to your laptop yourself but there are some How-To's on Youtube.
    \nI have made some good experiences with the Crucial and Intel SSD's - they were reliable and deliver a great performance.
    \nEDIT:
    \nYour Laptop supports M.2 SSD's with a formfactor of 22x80mm.\n\"M.2

But your manual does not say which M.2 Key Port it features - there are 2 different ones. \"Different
\nSource: Kingston SM2280S3 120GB M.2 SATA SSD Review on legitreview.com

\nThis will fit your laptops M.2 SSD port :)\n\"Measurements

\n\n

\n\n

If you want to buy a SSD from another company then make sure to get one with B&M key connector and with a formfactor of 22x80mm.

\n\n
\n\n
    \n
  1. Get a regular SSD. Your Laptop has a built-in DVD-drive - if you are not intending to use it that much you could swap it out and replace it with a SSD. If you plan on doing that you would have to get yourself a SSD and a SSD/HDD Cage. Then you would have to replace your HDD-drive with this cage which houses your SSD.
  2. \n
\n\n
\n\n

So it depends on which road you want to take. You can't go really wrong with many of these. My Suggestion would be a Intel 535 M.2 SSD. But if you want to replace your DVD-Drive with a SSD then I'd probably go for the Crucial MX200 or BX100

I am looking for a router whose built in firmware can ensure QoS such that if one user is say downloading torrents (completely hogging up the bandwidth) it will slow his speed down to the point that others' ping will stay low. This is to ensure that if someone is playing an online game (where RTT is essential), to them it will be as if nothing has happened as their ping will not shoot up.

\n\n

Do note that I do not want any per application/port setup as there are many ways to hog the bandwidth (not just torrents) and there are many games as well and it will get arduous to configure each thing separately.

\n\n

This functionality definitely exists in an open source router firmware called Gargoyle (the feature is called MinimizeRTT). I am using this currently and it works like a charm.

\n\n

My real reason for asking this question is that there must be at least one big router company that thought that this would be a good idea, especially when working code is available openly by Gargoyle.

I realise that I'm a little late to the party and you may have already solved this problem yourself but thought I'd chip in with my two cents in case it would be of any use.

\n\n

The router you are absolutely looking for is the Netduma R1, made by a small UK based startup and based upon a Mikrotik router board loaded with Netduma's own firmware.

\n\n

This router uses a completely unique anti-flood algorithm that completely eliminates ping spikes due to other users on your network downloading, streaming etc and it absolutely works.

\n\n

The router also allows bandwidth prioritisation per device, as well as including a unique patented geo-filter that allows you to specify the distance (radius) of servers you wish to play on from your home location when playing on dedicated servers as well as refusing users from other parts of the world if playing a peer-to-peer network game.

\n\n

You can also specify maximum pings and either blacklist players by gamertag/PSN ID or IP address or whitelist friends who maybe outside your geo-filter/ping filters but you still wish to game with.

\n\n

I have used the Netduma and can honestly say that whilst the promise sounds too good to be true this is one device that isn't actually snake oil and does actually work as advertised, In fact I would go as far as to say that this is the single biggest improvement to my online gaming I have ever made it really is transformative when configured correctly.

\n\n

The features on the Netduma are light years ahead of what is currently available on so called \"gaming\" routers primarily because of the brilliant implementation of the software.

\n\n

The only downside to the router is that it only comes with 2.4 GHz WiFi , however this issue can be circumvented by adding in an addition WiFi access point and turning off the routers WiFi signal, in my case I paired the router with a Ruckus Wireless R710 AP and the results are superb.

It's got one VGA output and one DVI output with a DVI-to-VGA adapter, it uses one of your board's PCI slots rather than a PCIe slot, and it's well-supported by the open-source ATI drivers (R100 column). I haven't found a solid source for maximum resolution, but it appears to be at least 1600x1200.

Alternatively, if you can find one, I recommend a GeForce 5200, again with a PCI interface. One VGA and one DVI-I is common, it's somewhat more powerful than either the Radeon 7000 or the GMA950, and it's got decent support by the open-source drivers.

What is your opinion on this configuration? And more importantly, is there anything missing? For instance - this configuration is running two processors - is the 750W power supply enough?

\n", "Title": "Server hardware recommendation/validation for hyper-v", "Tags": "|server|virtual-machines|", "Answer": "

The 750W PS is perfectly fine for your config.

\n\n

This is just my opinion: I usually go for more smaller drives than less larger drives. If you get 8 600GB drives you will get the same storage capacity (or very close to it, depends on how they are formatted by the FS) but you will get a large speed bonus, which will generally be a good thing if this server is going to run VMs that are I/O intensive.

\n\n

If this server absolutely needs to be running 24/7 i would also get a secondary PS and run it on a different power circuit. If one goes down than the other one can take over.

I am currently trying to upgrade my rather outdated (but reliable :) ) PC without spending very much money at all. I have these two similar graphics cards in my possession right now.

\n\n

EAH4350 Silent

\n\n

EAX1550/TD/256

\n\n

As you can see both cards are similar, yet the second one has half the video memory and double the effective memory size of the first?

\n\n

My question is, what is effective memory, how does it relate to video memory and/or the performance of the card? (And to be extremely general, which card will run Skyrim better?)

\n\n

** Basic specs on my PC **

\n\n
    \n
  1. CPU: Intel core2 duo @ 2.8GHz
  2. \n
  3. RAM: ddr2-1066 4GB (2X2 GB)
  4. \n
  5. OS: Windows xp sp3
  6. \n
  7. GPU: Currently have the EAH4350 Silent installed
  8. \n
\n", "Title": "What is the difference between video memory and effective memory size (GPU's)", "Tags": "|graphics-cards|", "Answer": "

I finally worked out what 1GB effective memory actually means in the EAX1550. ATI has a feature on some of their cards called HyperMemory which allows the card to steal some of the the systems main memory (RAM). The reason for doing this is that it allows for ATI to produce cheap video cards with a large amount of processing memory without the need for expensive on board memory.

\n\n

The downside to this is that it requires the system to surrender a portion of its RAM for graphics processing. Also, due to the fact that a large portion of the GPU's memory is not on board, large amounts of data must be moved between the card and the main system causing some latency issues.

\n\n

As for which one plays Skyrim better, i have yet to run some tests but i will probably post my very unofficial results here for anyone who is interested. (My money is on the card without HyperMemory, as it should run slightly faster, albeit with less memory)

So I'm looking for a computer to learn game development on, that should cover the following bases:

\n\n

(I'm willing to compromise on a count or two if it's a better choice overall)

\n

after a lot of searching I actually found a few that covered my bases, except the last one (battery life). since by definition powerful laptops require more power, most of the rigs I looked at didn't have amazing battery time.\nknowing this I looked for ones with USB 3.1-C ports thinking I could charge them via power bank.\nbut after settling on the ASUS GL552VW/GL752VW, I found out that it does NOT support the PD 2.0 standard meaning it's useless for charging and I would be limited to the lackluster ~4hr battery.

Is the AMD still viable?

\n\n

I'm looking at a mild upgrade to my existing rig, including video card and memory, not much else. I'm curious if the 8320 is still adequate considering the reasonable cost of the 6500 Skylake (which is considered pretty good for its price but no overclocking). I do some gaming, but don't care about 4k or reaching super ultra high whatever. I plan on a 380x AMD gfx card, so that part should be good to go.

\n\n

If I go the AMD route, I only need to swap CPU, as I currently have an AMD system and compatible MB. Whereas, going Intel would require new MB, new RAM, and the CPU.

\n\n

Aside from normal computer usage (internet, email, etc) and playing WoW or BF4, the AMD should be just fine. Right? Or would it be best to spend the little extra and go Intel, considering the new platform means I can upgrade the CPU later.

\n\n

I am currently using an AMD FX-6100 with a Radeon 6770. Any upgrade is an upgrade. As for budget, I can do the Intel route for about $575 USD or the AMD upgrade for about $400. I really just want to know if the 8320 is still a viable option or just bite the bullet and go all in Intel.

I would get the same fan that is on the cooler. You know that it will fit on the cooler and have the same performance. I would make sure that you have enough room on the other side of the cooler before purchasing the additional fan, as it look like you might have another heat sink in the way (it might not be, its just hard to tell from your picture at that angle).

\n\n

It appears that this fan is the same one that comes with the cooler. If you do not decide to get the same fan, I would get a fan that has the same RPM as the one on the cooler, as the fan with the lower RPM will just get in the way of the faster fan, reducing the cooling effectiveness.

I'm in the market for a new gaming laptop. Because you can't easily upgrade the components in laptops, I'd ideally like to buy one that has the potential to run VR. However, my day to day needs do not demand that much GPU power, so I'd like to buy the minimum hardware spec I can get away with.

\n\n

I know I could wait until the headsets come out and a new generation of GPUs is around to support them, but I'd prefer to make the purchase now if possible, as it'll save me a bit of tax.

\n\n

So I've done a bit of research and my understanding is that Oculus are suggesting desktop grade GTX970 is the minimum. That would suggest that a 980M ought, in practice, to be able to support an Oculus Rift. However, I believe I'm right in saying that the 980M is still integrated rather than a separate board, and that it uses Nvidia Optimus. To be frank, I don't entirely understand what this is, nor why it's a problem for VR.

\n\n

I also know that there's a new desktop grade 980 out, suitable for laptops. This is expensive and doesn't have wide distribution. I also don't know whether this is board mounted/uses optimus or not. I also don't know if it's G-Sync enabled, as this seems to be a good idea for VR.

\n\n

I was originally looking at the Asus ROG G752VT as it seems to offer excellent value for money. But it's got a 970M, which I suspect isn't going to be enough and is going to run into the optimus problem.

\n\n

So the baseline question is: what's the mininum specification I need to get a laptop-ready VR.

\n\n

Bonus points if you'd be kind enough to break this down into:

If the laptops, MSI GT Series GT72S DomPro4K-059 and MSI GT Series GT72S DomProG-070 are too expensive. I would suggest going with a Razer Blade Stealth with Razer Core or Alienware 13 with a graphics amplifier. They will allow you to keep your price low while being VR compatible in a flexible way.

I'm currently doing 4k gaming - a 980TI is probably the most sensible option - its 90% of the performance of this generation's titan at 75% of the cost stock but I'd wait for the next generation if possible. On one hand they promise massive improvements. On the other hand, last gen hardware is cheaper.

What do I base this on?

\n\n

I'm running a ivy bridge core i7 with 16 gb of ram. I'm rarely ram or CPU throttled. I do have a 980ti which performs adequately for my needs. That said I don't seem to think I hit the limits of my video card ram, and I seem to have some headroom with my GPU with most games, and I usually turn it up past the nvidia recommended settings. .

\n\n

My advice would be to do a video card upgrade, but to wait a bit. If you must buy one now, while its pricy, a 980TI is likely your best option for dx11, single card gaming. That said, the next generation should have similar performance or better, and there's a few new interesting technologies - smaller process sizes and Ram varients that might make it worth the wait. Don't get me wrong, my current card is glorious but we should be seeing things like HBM this year on most cards.

\n\n

That said, things may change soon - AMD's cards are doing really well at dx12 (and there's big price cuts on the high end R9s), and vulcan's coming out. And of course new cards promising more performance.

One alternative would be to use an internal Ethernet add-on card. It's a lot better than the USB solution usually...

\n\n

One (very cheap) example:\nhttp://www.newegg.com/Product/Product.aspx?Item=9SIA5M11TB9358

\n\n

Advantages to other solutions:

\n\n\n\n

It has better bandwidth and reliability than the USB options suggested earlier, and it can be cheaply added to ANY motherboard someone else suggests as the solution, which allows total overall cost to be much lower (given that 2x ethernet port motherboards are indeed generally expensive). With an adapter like this, almost any motherboard that supports his chosen CPU will work just fine for your purposes.

I have an ASUS N56VB and have been researching laptop coolers for a while now (or maybe even too much).\nI checked the areas where the laptop overheats when playing games and noticed that it happens only on the left side. Even the hard drive, which is on the bottom right, is unaffected.\nAlso, I think the vents are not at the bottom of the laptop but on it's left side.\nThere are of course a lot of brands which make the choice even harder.

\n\n

Considering those circumstances, I am not sure whether to buy a cooling pad with 1 fan, 2 or 4 fans. 1 fan lies always in the center, and the heating occurs on the left side only. 2 fans might be sufficient. 4 fans, while at the right areas, seem redundant.

\n\n

Here are some pictures:

\n\n

Some measurements - \n\"Measurements\"

\n\n

The side vents - \n\"Side

\n\n

I thought that maybe this will be good:\nhttp://www.amazon.com/BlueFinger%C2%AE-Arrival-Notebook-2200-4000%C2%B110%25RPM-Ultra-portable/dp/B0148IKWYS/ref=sr_1_1?ie=UTF8&qid=1455965509&sr=8-1&keywords=Bluefinger+2+in+1\nAs it has both a cooling pad and a cooler on the side, but there are not enough reviews for this product.

\n\n

Another good product is this:\nhttp://www.amazon.com/Cooling-TeckNet-Notebook-Adjustable-Temperature/dp/B016CL2F5S/ref=sr_1_1?ie=UTF8&qid=1455965555&sr=8-1&keywords=TeckNet%C2%AE+Gaming+Laptop\nMainly because of the temperature display and the on/off switch (which hopefully also turns off the fans themselves).

\n\n

Or perhaps this one (or something similar? there could be others that are way better):\nhttp://www.amazon.com/Thermaltake-Massive23-Notebook-Oversized-CLN0015/dp/B003ZUXXWO/ref=sr_1_1?ie=UTF8&qid=1455965583&sr=8-1&keywords=Thermaltake+Massive23\nPerhaps one fan is better? I'm not sure.

\n\n

So far I'm thinking about the BlueFinger cooler (mainly because it is pad&side cooler) but the lack of reviews is disturbing. I would really appreciate your assistance as I have never bought a laptop cooler before.

\n", "Title": "Not sure about which laptop cooler to choose", "Tags": "|laptop|cooling|", "Answer": "

Most of the models linked here have fans mounted in a fashion that makes them work like axial fans with a big dead spot\u00b9 in the middle and directly blowing at the mostly closed surface or trying to suck air from it, which probably causes more turbulence in the fan itself than actual cooling of the device. I don't think this is a very efficient design, neither do I think that the mentioned extracting cooler fan helps support the CPU cooler in the laptop doing it's job better. It tries to get the hot air out faster, but doesn't help getting fresh and cool air into the system.

\n\n

We had some older very hot running laptops in the office here in Germany. I bought an Arctic NC suitable for 14 and 15 inch sized laptops which made it run significantly cooler and I have used it since then for most of the laptops I worked with in the office. It's rather small and mostly quiet. I would recommend looking for such a device that works more like a radial design and covers the entire surface without any dead spots. The downside of this particular cooler is, that your laptop only stands on two points on this fan which may be bit unstable in some cases compared to the other designs.

\n\n

\"enter

\n\n

As I said I live in Germany where it doesn't get very hot and our offices are outside of town, my co-worker in Hungary living in a not well ventilated apartment had more severe heat problems with the same laptop model (trying to cool with +40\u00b0C fresh air). So it also depends on where you live.

\n\n

  1. TMD fans were proposed as a solution to the dead spot problem more than 10 years ago, but never got as popular as the radial based designs you can find today.

Several weeks or months ago I read a discussion, probably on Hacker News, and in it somebody recommended a router that fixed all his router problems. Reception was excellent, and it had an option to configure guest access on a separate network, secure from the rest, without much effort.

I don't remember the name of the brand. I believe it had U and Q in it, but I'm not sure. The router itself was round and white, like the Engenius, but as I remember it without the leds. Pricing was about 80 euros for the basic model, and there were pro versions for about 240 euros.

I am looking for an outdoor IP camera with night vision and good resolution, ability to cover distances about 100 m with good detail (registration plate, face etc.). There are some good recommendations in this question.

\n\n

It is quite common for theese cameras to have an SD card inserted and recordings can be saved there. Is there a chance there is some IP camera with built-in FTP, SFTP server, or with HTTPS download of recorded video files periodically (nightly)? Like it is possible from an IPCorder device. Or to setup FTP send to some given schedule, like every day at 22:00.

\n\n

Seems like VIVOTEK 8372 can be configured to send FTP data only when defined event fires, which could be OK, but it is not well documented how it actually works. From this link it seems that it is rather used for sending pictures from the camera to be shown on a web page which is quite useless for this purpose.

\n\n

Looking around my last hot candidate are Panasonic cameras WV-SFV6 series - in their manual there is on the page 160 an option Allow FTP access to camera. This seems to be promising, even there is a data structure on the last page that looks very well, any experience with this or anything similar?\nThe problem is that theese cameras are relatively expensive and perhaps installing less expensive camera tohether with NVR would be less costly.

In your price range it will be best solution because of GTX 980M GPU. It is the most important part for gaming in laptops. The rest will also meet your requirements. It has no USB 2.0 port but USB 3.0 is backward compatible so you can use one of USB 3.0 slots for USB 2.0 devices.

Because of the above criteria, I'm assuming that Bluetooth speakers are not effective, because I need to be able to move around with the laptop and still have connectivity. Also, there is a thick wall between the two rooms so they wouldn't be able to communicate with each other via Bluetooth.

\n\n

So my question is if you could recommend some Wi-Fi speakers that meet these critera \u2013 if there are any?

\n", "Title": "Wireless Speaker Pair that can play simultaneous audio from computer?", "Tags": "|audio|wireless|speakers|", "Answer": "

The original Hi-Fi Wi-Fi speaker company, Sonos, seems to be your fit. They have three product lines that are fully inter-operable with each other; in order of increasing quality (and obviously price): the Play 1, 3 and 5 at $200, $300 and $500 respectively.

\n\n

Despite the $50 budget breach per speaker, I include the Play 5 because you'll need at least one (or the CONNECT or the CONNECT AMP) for full source computer (Apple) audio (i.e. sources from non-Sonos compatible streaming apps). The Play 5 is also the only one with an AUX, the biggest speaker and as I mentioned the speakers are fully inter-operable, so you can mix and match.

\n\n

As long as you have at least one Play 5/CONNECT/CONNECT AMP connected to an AirPort Express, all models exceed your critical requirements:

\n\n
\n

Critical features:

\n \n

The Wireless speakers I am looking for should be able to source \n computer audio, and let me select where to play it at any time (yes for Apple devices via AirPlay):

Additionally, I would like them to:

\n \n

Support AirPlay streaming from iOS devices

\n
\n\n

And satisfy almost all optional features:

\n\n
\n \n
\n\n

Now in contrast to previous Sonos speakers, the latest ones connect directly to your Wi-Fi and don't require the old $50 bridge. Assuming a total budget of $900 for any 2 speakers and that you have an AirPort Express (additional $100 if you don't), to stay within it you could get (in order of preference):

\n\n
    \n
  1. (1 x Play 5) + (1 x Play 3) = $800
  2. \n
  3. (1 x Connect) + (1 x Play 3) + (1 x Play 1) = $850
  4. \n
\n\n

I'd go with option 1 myself because it's more than enough my for average (European) place. All the Plays sound amazing, but obviously the Play 5 really fills the room, so put plug that in your bigger/more frequented room with the AirPort Express next to it. If you don't have an AirPort Express you can get one and still be in your $900 budget.

\n\n

If you want to fill a large house, stretch the budget and get 2 Play 5s. Or buy 1 Play 5, test it and decide on another or a Play 3. The main lady will try, but she'll never keep you down.

\n

While watching an Antenna TV Channel (or a YouTube video, for example) if I press the * button on the Roku remote, a menu comes up on the left side of the screen. In that menu, there is an option called Picture Off.

\n

If you select Picture Off, you'll continue to hear the TV, but the display is turned off. After going into this mode, to turn the screen back on (later), you simply press the OK button (on the Roku remote) and the screen will turn back ON as before.

I recently got a new (to me) computer. It was a workhorse computer from a few years ago. I'm trying to rig it up to work with an SSD in its new life with me.

\n\n

Currently the motherboard has SATA II and PCIe x4 slots available. I purchased a SAMSUNG 850 EVO M.2 SATA III drive which I was hoping would wrok but because of my confusion on how the M.2 spec works the drive I purchased is not directly compatible with my motherboard. I was assuming I could plug it into a PCIe slot (obviously that was wrong), then I was hoping I could get a PCIe to M.2 adapter but because this particular drive is M.2/SATA which means if I get an adapter I'd have to plug it in to a SATA II port which is what I was hoping to avoid is the first place.

I am considering purchasing a new gaming laptop. After some initial research, I have narrowed the field down to two candidates.

\n\n

The Asus ROG G752VT

\n\n\n\n

The Medion Erazer X7843

\n\n\n\n

In spite of the fact that, on paper, the Medion is the more powerful of the two, they are roughly equivalent in price. This immediately makes me suspicious. Medion is a German brand which is sometimes sold in discount supermarkets. It's based on MSI \"Barebones\", about which I know nothing. Being German, it's hard to find reliable reports in English of its reliability.

\n\n

I was originally going to go for the Asus, but looking at the \"recommended\" specifications for some recent games it seemed that the desktop GTX 770 is a common fixture. Checking benchmark lists, it appears that the GTX 970M rates about 10% less power than the GTX 770, whereas the GTX 980M rates about 10% more. That made me feel it might be a worthwhile upgrade and I went looking for a system I could afford with the 980M, and the Medion is the only one I found.

\n\n

To lay out my concerns in plain language, I'm hoping someone can advise me on:

\n\n\n\n

In short, do I really need a 980M, and is the Medion really as good value as it seems to be?

\n", "Title": "Gaming laptops: Asus ROG G752VT vs Medion Erazer X7843", "Tags": "|laptop|gaming|", "Answer": "

There's a test of the Medion on this site:

\n\n

http://www.notebookcheck.com/Test-Medion-Erazer-X7843-Notebook.154482.0.html

\n\n

Just use Google Translate or similar and you'll see that it is even tested against the G752VT. Nobody can tell you whether one thing is worth it or not, but the test gives you pretty much all the information you need to make your own decision (screen, noise, temperatures etc. are all in the test)

\n\n

Edit: The site says that the screen is good, the performance is very high, the input devices are \"proper\" (my German isn't great, so that is the best translation I can give) and the negatives are that the CPU and GPU are soldered on and that the laptop throttles (turns down clocks/performance) on battery power.

The last couple of months I have been preparing for a return to hobby music production after a long hiatus. I have realised that my computer will not have enough storage space for my coming sample library, so I need to look at external storage solutions.

\n\n

I basically have two options:

\n\n
    \n
  1. Store the samples on a Gigabit Ethernet-connected Synology DS415+ NAS that's already on my network. I could potentially make use of double LAN ports if I purchase an extra Network switch, since all Ethernet ports on my router are already occupied.
  2. \n
  3. Purchase an external drive with either SSD or Thunderbolt (but probably not both \u2013 that would be too expensive). I am using an iMac from mid-2011 with Thunderbolt 1 and USB 2, but may upgrade to a new Retina iMac within 1-2 years, and not sure if now is a good time to invest in Thunderbolt 2 technology in an external drive.
  4. \n
\n\n

Questions:

\n\n

Which one of these alternatives would be advisable from both a technologically functional and cost-benefit purchase recommendation standpoint?

\n\n\n\n
\n\n

Purchasing limitations:

\n\n\n", "Title": "External Music Production Library: NAS vs. External SSD vs. External HDD Thunderbolt?", "Tags": "|ssd|data-storage|nas|thunderbolt|", "Answer": "
\n

Does it make sense to store relatively large sample libraries in a remote location?

\n
\n

It makes sense, but it's not at all beneficial. If you're going to be pulling samples into your project fairly often, you'll be much better off storing them locally so you only have to depend on drive connection transfer rates.

\n
\n

Would it be smarter to get a network switch to enable double LAN ports?

\n
\n

Like you said, this wouldn't matter at all if your computer is bottlenecking the network connection with one LAN port.

\n
\n

What's most future-proof solution given that I may upgrade my computer to USB-C and/or Thunderbolt 3 within 1-2 years?

\n
\n

The two options you're choosing from aren't desirable if you're focusing on future-proofing. Both will become completely outdated in 1-2 years because of the USB 2 and HDD technologies.

\n
\n
\n

External SSD with USB 2 or external HDD with Thunderbolt 1?

\n
\n

Transfer rate

\n

Taking into account the other questions, an HDD with Thunderbolt will do you well because you could connect several of these to a Thunderbolt hub and have little to no bottlenecking. Thunderbolt is rated at 1250MB/s per channel (but usually hits around 500MB/s) while HDD read speeds average around 120MB/s. This allows for a lot of room to expand your storage options later on. With an SSD-USB 2 setup, you have a connection speed of 60MB/s bottlenecking an average read speed of >400MB/s... Not too great.

\n

Cost

\n

Since you're looking for at least 0.5-1TB of storage space, choosing the SSD route will skyrocket the price very easily. A 1TB SSD will instantly put you over budget while a 1TB HDD won't even put you over half your budget. Also, since you're considering the future, it's better to spend less so you can potentially upgrade to a newer technology later on. You might find a good deal on an SSD with Thunderbolt for example.

\n

Availability

\n

Both options are fairly uncommon because USB 2 is being quickly phased out as a drive connection type and Thunderbolt on a hard drive is a mix of very old and very new technologies. Don't expect a small price tag on anything amazing.

\n

Recommendation

\n

G-Technology G-DRIVE Mobile 1TB 7200RPM 1xThunderbolt/1xUSB 3.0 (USD $190)

\n\n

A quality solution overall. But, again, you don't have too many options here given your price constraint. There are better products out there that sit outside your budget.

I have a line-powered (standard AC) device that sinks 50W in steady-state and I need to power it for 10 hours in case of service interruption.

\n\n

I'm assuming that I can use, say, a 500W UPS (50W * 10hr = 500Whr = 500W * 1hr) to power it for 10 hours.

\n\n

But where can I find that kind of UPS? Looking at, for example, CyberPower, I see the model I currently own will supply 600W for only 1 minute (if I'm reading the spec correctly here, under product features \"Runtime (half/full).\" (Actually, I don't know how to read that since it says full = 1 minute, half = 6 minutes, so maybe it isn't linear?)

\n\n

Anyway, where can I find a battery backed UPS that will supply 50W for 10 hours?

\n\n

Bonus questions: The UPS specs generally also use VA as units as well as W. Is this due to RMS factors for sine wave power or what? And does it affect my calculations?

\n", "Title": "UPS that supplies 50W for 10hrs?", "Tags": "|power-supply|ups|", "Answer": "

Computer UPSs are optimized to provide high power levels for a short period of time, the idea being to bridge a brief flicker in the mains power, or let you shut down cleanly during an extended outage. At low power draws, they are quite inefficient, wasting much of the battery's power as heat.

\n\n

Your best bet is to build your own UPS from an inverter-charger and a marine/RV deep-cycle battery. Something like this 600-watt inverter-charger ($400) plus a 60AH-80AH battery should work; given your low power draw and assuming you don't switch to battery power very often, you might even be able to get away with using an automotive battery.

Considering hardware for a gaming laptop. Not building my own, but found a great deal on a machine from last season still sporting a 4720HQ processor.

\n\n

Comparing benchmarks between the Haswell 4720HQ and the Skylake 6700HQ seems to suggest they're roughly comparable. The 6700 is, on average, about 5% better but some sites, such as cpuboss, actually suggest the older chip is marginally faster. There are lots of benchmarks and I'm not sure which to trust as regards a machine intended primarily for gaming, but from speed alone the 6700 doesn't appear to be worthwhile.

\n\n

However, speed isn't the only improvement in Haswell vs Skylake. Most of the others don't interest me. Better integrated graphics aren't much use in a machine with a dedicated GPU. The support for DDR4 isn't a big deal in a laptop where I'm unlikely to be upgrading the default RAM. The effeciency gains aren't helpful since I spend most of my time plugging in to a power socket.

\n\n

The differences in connectivity though, could be a big deal, and that's support for Thunderbolt and USB 3.1.

\n\n

About a year ago there was a big explosion in interest about Thunderbolt, partly because it offered the possibility of running desktop-grade GPUs as an external plug-in to laptops and all kinds of other cool stuff. Right now, I can't ascertain whether this has lead to any tangible use cases or is likely to. I'm not even entirely sure, to be honest, whether you can even buy non-Apple laptops with Thunderbolt ports, or how to find them (it seems to be referred to as USB Type-C in some places).

\n\n

So, is it realistic to go looking for a Skylake laptop with Thunderbolt, with a view to plugging in some monstrous desktop GPU, or some other reason (are the benchmarks lying)? Or should I stick with Haswell for now?

High spec Haswells and Broadwells are going for absolute bargains right now and are excellent machines for most people that want very good gaming with normal work/social use cases.

\n\n

But if you primarily want to game on your laptop and if you don't want to wait and can find the 6700HQ (or something else) with something like a GTX 970M and a Thunderbolt 3 port (preferably more), then go for it. That should last you 2 years by which time there'll be much more external desktop GPUs to upgrade to via Thunderbolt 3.

To give an example (for non-hardcore gamers), Acer will be releasing a dock which features an NVIDIA GeForce GTX 960M graphics card, two DisplayPorts, a HDMI port, three Type A USB 3.0 ports, a headphone jack and an Ethernet port. Expected to be about \u20ac300, likely to be tied to Acer laptops.

\n\n

For serious desktop graphics cards, a number of enclosures are out now or just around the corner that take a full PCI-E x16 slotted card. Thunderbolt 3.0 doesn't nearly have the same bandwidth as PCI-E x16 and this does lead to a performance hit compared to a desktop (Asus say 1-5% fps hit for theirs); but a bit of perspective: you're running a desktop graphics card on your laptop :-O.

\n\n

There's the Asus ROG XG Station, as in a YouTube link above, tied to Acer laptops. Likely to be GPU manufacturer agnostic.

\n\n

Razer have Core, which is a docking station designed to enhance their ultrabook grade Blade Stealth, but is GPU and PC manufacturer agnostic. From what I gather, hot swap drivers drivers are built into the Core and load on the fly, unlike the other offerings where you'll have to power of your device to disconnect the external GPU. It has a built-in 500W power supply (supports a 350W GPU), four USB 3.0 ports and Ethernet port. Already shipping in the US for $500 (without a GPU), $400 with a Blade Stealth ($1000 starting). Expected to ship in April for Europe. This is the one I'm really excited about :-D.

\n\n

AMD are working on XConnect (with Razer), intended to be at least PC manufacturer agnostic.

\n\n

So if you get a Skylake gaming machine with Thunderbolt 3 soon, which typically last for 2 years, by then there'll be plenty more GPU and PC manufacturer agnostic enclosures around. If you go Haswell, although much cheaper now, you'll have to replace the whole machine at upgrade time.

I'm not even entirely sure, to be honest, whether you can even buy\n non-Apple laptops with Thunderbolt ports

Thunderbolt 3 is no pricey passing technology like Thunderbolt 1 & 2 before it. Nor should it ever be thought of as an Apple feature like Thunderbolt 1 & 2. Major manufactures have already released laptops with Thunderbolt 3 for their higher priced offerings and only more will follow suit. Here are only some examples.

As has been said, Pascal is coming soon, and is expected to have greater performance increases than the Kepler to Maxwell transition (Pascal should be released to public around the end of Q2). However, I wouldn't dismiss multi GPU setups out of hand, though perhaps it makes more sense as a later upgrade.

\n\n

Why multiple GPUs are better with Pascal:

What you should also consider:

\n\n

AMD's Polaris is also releasing around the same time, and is supposed to have competitive performance per watt. Of course, you might run into problems with vendor specific software, such as those using CUDA, but it goes both ways (well, slightly more in favor of Nvidia, owing to their market share), and AMD hardware generally have better OpenCL performance. If you're not worried about power consumption and you want your computer now, 2 R9 390s would be decently better performing than 2 GTX 970s at high resolutions.

I am starting a home server build. I am on a tight budget and aiming for the most quiet and low power build. I managed to salvage an Intel Xeon X3440 Processor from an old server.

I am looking for a recommendation for a low cost server board that will support my processor.

I am trying to setup a laptop for my grandparents for video calls, who certainly don't know how to use most technologies.

\n\n

My plan is to setup a video chat app on boot and use a reliable command-line interface (CLI) to pre-select numbers for them. There will be only two numbers/addresses, mine and my brother's. I have been looking for video chat app that provides an official, long-term-supported CLI on Linux. Google Hangouts and Skype both have third-party CLI, which may not be up-to-date with the official releases in the future. If my grandparents accidentally update the app, the whole setup may break.

\n\n

The choice of laptop is also crucial. The most important feature here is durability, because the laptop may be dropped to ground accidentally, or a cup of water may go directly onto the keyboard. CPU is not an issue as long as it is enough to power Linux kernel and the app, because video-call is IO-bound I believe. Hard-disk size doesn't matter, and 4GB of RAM is good enough.

\n\n

I'd love to let my grandparents skip the steps of starting apps, logging in, selecting video calls, push numbers/addresses etc. For that I will need to setup a bash or other scripts to do these with CLI on boot. That is also why I want to install Linux on the laptop (mainly because I am not familiar with Windows' shells...)

I purchased a Kindle Fire for my 80 year old aunt and showed her how to use three apps on it. Netflix, Skype and email. The out of pocket cost was just over $50 including the case and a stand (so she could watch movies)

I positioned the icons for her so that they were the first things that were there when the device was turned on. That was Christmas 2015.

You might want to investigate the Thinkpad from Lenovo as well. W550, P50, P70... They are all high end machines and they have various options so that you can tailor the machine to your needs.

\n\n

But the \"killer\" feature - for me - was the docking station (purchased separately) that gives the ability to move the laptop around while still having a \"proper\" screen, keyboard and mouse when you are sitting in your home office. The best of both worlds.\nWhile you didn't mention \"docks\", maybe this could fit all of your keyboard requirements if 90% of your work is done on a desk and not \"on the go\" (you can then purchase any keyboard and plug it to the dock, which is what I did with mine).

\n\n

Support is great as well and professional (at least here in the UK) - and when I purchased mine, I got the extended warranty which was very cheap.

\n\n

Also, the Lenovo laptops are fairly easy to open and there are lots of manuals in case you want/need to replace the components by yourself.

You should not go with a card with more than 200W TDP as you have only a 550W power supply. It might work, it might not.

\n\n

600 EUR is way too high of a budget for just a new graphics card. If you want an equivalent graphics card to the 6850, you could go for a GTX 960. It's faster than the 6850 in fact, and consumes similar amount of power(120W for the 960, 127 for the 6850).\nUltra-high end cards like the 980 and 980Ti will be overkill for you, since your PC is old, and they're pretty fast, over 4 times as fast(or even faster) for the 980Ti. The 980Ti also consumes a lot of power, 250W.

\n\n

If you want to go for a bit of futureproofing, go with a 970 or an upcoming Pascal card. The 970 is an awesome card at $330 with a power consumption of 145W. Pascal cards are new ones coming with an architecture change, meaning they'll be significantly faster for the same amount of money. But you'll have to wait two months for them.

In order to use SLi, you need to have matching graphics cards.

If you are looking for a new single video card of comparable power which can also support multiple monitors, I recommend the GTX 750 which can be found for around USD$100, or the current GTX 950 for about USD$140. The GTX 660 Ti is capable of supporting three monitors, but can be difficult to find because it has been discontinued.

\n\n

Virtually any video card sold in stores today will support multiple monitors (at least two) and be capable of web content and bluray playback. Bear in mind that ATi video cards will need to use DisplayPort (or a powered adapter) in order to use three displays simultaneously.

In order to cover Windows, Android, Mac OS-X, and iOS, you'll need a two part solution.

\n\n

As you've already discovered, Miracast is a wireless display standard. It is effectively HDMI-over-wireless. The Wi-Fi Alliance maintains a list of compatible products. Note that it can be called different things by different vendors; Samsung calls it \"AllShare Cast\" for instance.

\n\n

Windows 8.1 and Windows 10 support Miracast. It depends on hardware support in the GPU, which modern Intel CPUs have integrated. Just be aware that having the right OS does not always mean the computer has the right hardware.

\n\n

The same goes for Android - 4.2 and up have the software capability, but it's only useful if the phone or tablet has the hardware capability.

\n\n

On the other side...

\n\n

Apple has excluded themselves by Apple's choice, forcing their customers to purchase an AppleTV box as well. On sufficiently recent Intel-based Macs, part of the hardware to use Miracast/Wi-Di is theoretically there in the CPU, but there's no way to access it.

\n\n

In order to get the same capability for Apple devices, you'll need to include an AppleTV in your setup. The AppleTV is small, so you can probably find some way to fasten it to the same mount as the projector and just leave it up there. It has Wi-Fi, so you don't need to supply anything but power.

\n\n

In summary: Your projector will need Miracast-capability and an HDMI port for the Apple TV.

I intend to buy a 15.4-inch MacBook Pro 2.5 GHz Quad-core Intel i7 with Retina Display. The latest edition offers AMD Radeon R9 M370X, while the previous one has a Nvidia GeForce GT 750M.

\n\n

I will primarily be using computer vision and deep learning algorithms. So, there is heavy possibility of using CUDA too.

\n\n

Which one should I opt for?

\n", "Title": "Which Mac should I buy? One with the Nvidia GeForce GT 750M or the latest one with AMD Radeon R9 M370X?", "Tags": "|laptop|graphics-cards|", "Answer": "

If you plan to work with Nvidia's CUDA framework right away to do some GPU-based computations (neural networks primarily), you should stick with GeForce 750M laptop.

\n\n

However, 750M's memory is only 2 GB (as the R370X is), so you will not be able to fit any big model into your GPU either way and will be forced to use either cloud instances or buy a separate GPU and somehow connect it to your Mac so the choice is really not too much relevant.

\n\n

If you don't have any immediate plans to dive into CUDA-based computations, buy either the cheapest option (750M Macs are previous generation, so you will buy them refurbished or used and that may save some money), or the newest (which is R370X) since it will be brand new and you will enjoy warranty period at its fullest.

\n\n

Also, Apple did release the Metal framework for native shader programming in OS X, which allows to use literally any supported GPU from OS X to program your computations, and there are some frameworks that use that possibility (Memkite for example) - that will give you deep learning and computer vision on any mentioned GPU (and even on built-in Iris Pro which is built into the CPU). But the support of Metal is in its early stage, so there are not too many frameworks and projects using it for machine learning (though, you could pioneer in that).

It not only depends on your CPU. Games differ by CPU utilisation some are more CPU dependent (for example Arma III) some are more GPU dependent (for example Far Cry 4, Witcher 3).

\n\n
\n\n

To avoid CPU bottlenecking in all games I would recommend you:

\n\n\n\n

If you compare versions with the same amount of VRAM the results are comparable. I would personally recommend version with 4 GB VRAM because new games use more and more VRAM.

\n\n

To avoid CPU bottlenecking in GPU dependent games I would recommend you:

\n\n\n\n

The second option is in my opinion maximum for your overclocked Athlon. I would recommend not to go higher than GTX970 or R390 with your CPU. From this duo I would recommend GTX970 if you want to play only in FHD and R9 390 if you want play in higher resolution.

Edit: What case do you use with your ITX motherboard ? How long GPU will fit to your case ? It can be important if your case is not aired enough you should look for card with lowest TDP.

Functional Requirements

\n

I need a reasonably portable device that would allow people to use their laptops to connect via WiFi and navigate to a domain name I would tell them. The domain name would serve a web page that would have links to files for download that would be hosted on and served from the device.

\n

Use-Case Requirements

\n

My use-case is for making 1 hour presentations I would like to run like a mini-workshop so I expect to have ~25 people connected and downloading, all at the time same time.

\n

What is the Specific Use-Case?

\n

Basically I want give a presentation to people about how to set up an open-source local development environment for WordPress and so I need people to be able to download the required files to their computer at the start of the presentation.

\n

Why These Requirements?

\n

WiFi Internet tends to be slow and/or unreliable at the locations where I will be giving these presentations, and my goal is to get as many people to actually start using this local development environment I built as I possibly can so I want to ensure successful setup for as many people as possible.

\n

Assumed Technical Requirements

\n

Obviously the device will need to be a WiFi access point, it would need provide a web server, DNS server and DHCP server and the domain name such as downloads.lan would only be visible to them when they are connected to the device.

\n

Non-Requirements

\n

The device does NOT need an upstream connection to the Internet. All it really needs to do is give them a special purchase WiFi access point to connect to, download files and then disconnect.

\n

But Nice-to-Have

\n

However a nice-to-have would be to have the device connect to an upstream Internet connection using DHCP -- in the case such a connection is available -- then proxy the traffic to the Internet (except traffic to downloads.lan), assuming the device could handle lots of connections. But again, that would just be a nice-to-have, not a requirement.

\n

"Failed" Attempts Thus Far

\n

So I have tried several things thus far that either did not work or that were far from optimal.

\n

LibraryBox on TP-Link MR3040

\n

My first attempt at this was to buy a TP-Link MR3040 and install LibraryBox software on it. Unfortunately, it took over 10 minutes to download the necessary files with only 1 computer connected; far too long. So the device needs to be fast; i.e. have lots of bandwidth.

\n

Apple Time Capsule

\n

I then looked at an older Apple Time Capsule I have. But it does not support a web server so it would be more technical to access, and it is on the very heavy end of portable. This may be my fall-back, but I am hoping I can find something better.

\n

Ubuntu + Hostapd + Lenovo IdeaCenter Q180

\n

I then tried to set up an old Lenovo IdeaCenter Q180 I had laying around by installing Ubuntu 16.04 LTS and Hostapd, but I had a nightmare trying to get everything configured correctly all at once.

\n

I started with Ubuntu Server but could not get it to connect to my WiFi -- which is necessary to download and install software -- so I switched to Ubuntu Desktop which has a GUI and thus I could get WiFi connected, but I could still not figure out how to get Hostapd to work. Evidently it needs to control the WiFi and yet Ubunutu Desktop does not want to let go of the WiFi.

\n

I feel certain this would work if I could just figure out how to configure everything. I expect maybe I need to buy another WiFi adapter for Hostapd to use like maybe the TP-LINK TL-WN722N but I don't want to go down another dead-end and I am not much more than a beginner as Linux and I may not be able to figure it out on my own.

\n

Summary

\n

At this point I am happy to spend money to solve the problem. I am happy to buy a different device if you can point me to something that will work. (I'd even hire someone to build it if the fee was modest!) I just want something that will work and meet my requirements, and not take 20 hours of my time to get working.

This unit comes with a handful of unique features, like the fan test button. With this, you can test the operation of the fan even before installing the PSU into your case.

There I saw that vivoactive and Garmin Vivoactive HR. is chargeable every 3 weeks. That is FAR FAR plus. I think that's what I am going to choose. It has all the features I need, like heart monitor.

\n\n

Obviously I recommend the exact same thing I am choosing. So before I go ahead and buy, please let me know if I am wrong.

\n\n

The HR model have barometer. I am not sure what it's for. But a plus. I like the look of the vivoactive normal.

\n\n

By the way I was going for Garmin Vivoactive because http://comparewear.com/wearables/?vs=gearS2&vs=vivoactive&vs=vivoactiveHR&vs=band2 said it has heart rate monitor. The thing is, https://www.shufflerun.com/garmin/vivoactive-hr-vs-garmin-vivoactive/ says that it's not 24/7. The heart rate monitor seems to be consuming battery. Tough choice.

\n\n

I would pick the vivoactive VR if it can last 3 weeks between charge (say by turning off 24/7 heart rate monitor). I would also prefer watch with non rechargeable battery.

I am looking to purchase a laptop pc for running Windows 10. I am looking for something that is strong and rugged like the old Thinkpads used to be. Something with a strong and \"non-squishy\" keyboard.

EDIT: Just wanted to post up that I ended up getting a Lenovo Thinkpad P50 and have been very happy with it. I was able to upgrade the RAM to 64 GB. I installed an M-2 SSD drive. Plenty of ports. Nice solid feel. I even purchased a docking station for $200 which gave me additional Display Ports. I currently run two external monitors and the internal display.

I am looking for a home office printer as my mother's current HP C310 has finally died completely, the print head has failed and they are unable to source replacement parts.

\n\n

The requirements are as follows:

\n\n\n\n

The optional nice to haves would be:

\n\n\n\n

I have been advised by the printer repair guy that we should consider printers with the print heads built into the cartridges, is this sound advice?

\n", "Title": "Home Office Inkjet Printer", "Tags": "|printer|scanner|", "Answer": "

We ended up going to a local PC store today so my mother could physically examine the printers. I will give a brief run down of the printers we looked at, it may help others with their choice.

\n\n

My mother had already decided that having an SD card was now a must rather than a nice to have.

\n\n

HP

\n\n

The store had a decent range of HP MFP's however none of them had all the requirements. They were missing either one or two different requirements. For example, one had 4 colour inks but was lacking the SD card slot, where as another had all the requirements but the coloured ink was in a single cartridge.

\n\n

The build quality was pretty solid across all the models and the prices were roughly similar with a rough average of about \u00a3120.

\n\n

Epson

\n\n

It looked like the store had quite a range of Epson printers, many in budget or under. I tried to insist that we should at least look at them in the interests of fairness but was over-ruled. I am only mentioning them here as balance.

\n\n

Brother

\n\n

There were two Brother devices that met our requirements apart from build quality. The display models looked shabby and flimsy, especially considering the prices of them were quite high. That said they both made our shortlist because they could handle A3 paper. They were eventually discounted as we felt they would not stand up to regular use.

\n\n

The models we considered were:

\n\n\n\n

Other

\n\n

The store we went only had a single Samsung printer and a single Lexmark printer available. The Samsung did not have an SD card slot and was well out of budget and the Lexmark was a standalone printer with no scanning capabilities.

\n\n

Canon

\n\n

I have left Canon until last as we ultimately ended up getting a Canon device. The build quality of all the Canon's, even the sub-\u00a350 ones, was excellent. On a similar par to HP.

\n\n

We were also hugely impressed by the design philosophy that had been followed on the mid-range printers, they looked \"unprinterish\".

\n\n

The two that made it on to our shortlist were:

\n\n\n\n

These are almost identical printers but we ended up choosing the Pixma MG6851. The things that swung it were the fact it was on sale at \u00a380 and the fewer inks. My mother was concerned that the extra \"grey\" cartridge in the MG7751 would make the ink more expensive in the long run, even though she preferred the minimalist look on the MG7751.

(Sorry for the title, but I'm pretty ignorant when it comes to home entertainment equipment)

\n\n

Recently, I got a 48\" TCL Roku TV to replace a 59\" Sony projector TV. It's pretty nice, with a good image after some fiddling and with the flexibility of the Roku software, but it has a problem; the sound leaves a lot to be desired.

\n\n

Because of that, I'm thinking of saving up to get an external sound system. I figure I might as well go all-out and get some sort of 5.1 or 7.1 surround sound system.

\n\n

Since the TV only has a 3.5mm audio jack and an optical audio out, running one of those to a surround system would be out of the question, especially since at least the 3.5mm Jack outputs terrible quality sound.

\n\n

I believe a some sort of A/V receiver would be the best option. It would need to have 3 HDMI inputs (at least), possibly a few composite inputs, and optical audio in so that the smart features of the TV could have sound run to the system.

\n\n

The problem I have is a complete lack of knowledge on how to look for what I need. Do receivers have the capability of acting as a sort of switcher for the inputs, just needing one cable to the TV? Do they work as passthroughs?

\n\n

I have no idea how to look for one, and I don't know if this is even the right place to ask (or if I asked correctly), but I'm more than willing to completely rewrite the question if that helps anyone help me.

I know this is old. But I'd like to suggest folks look at Sound Bars.

\n

While I personally have a (older) Yamaha AVENTAGE AV system (the cheapest of the line), 5 inputs and 1 output, hooked to some big speakers. Sound-bars have become popular in recent years. A friend of mine switched his AV system to a sound-bar.

\n

They may be less expensive than going full AV system.

\n

The big feature I learned about is ARC, or Audio Return Channel. This allows sound from the TV to go "backwards" into the AV system. Thereby using the HDMI inputs on the TV.

\n

Rather than plugging everything into the AV system, you can plug into the TV and go the other way. I watch live TV from the antenna and the sound comes out the AV speakers. The two ends decide who is the audio source.

\n

I recently bought an XBOX and didn't want to fiddle with the cluster of wires behind the AV system. So I did the lazy thing and plugged it directly into the TV. The audio is still Dolby-decoded and played on the AV system.

ASRock Z170 Extreme7+ is very good motherboard but only if you want overclock your new setup if not Z170 chipset will give you only support for higher frequency RAM what won't give proportional efficiency to the price paid for it.

Basically I bought a pair of omni 10 speakers.

Basically I want to connect my pc to my omni speakers using regular 3.5 mm. However, I don't want to use 3 m normal audio cable to connect my PC to OMNI 10. Doing so results in high delay.

I want my PC to connect to a wifi that then connect to the speaker using 3.5 mm cable. Is that even possible?

The PS3 had 2 major advantages - it was an open system and the 'cell' architecture, which was easy to program for and fairly powerful. They were also slimline

I'd argue that the most sensible way to equal that would be a cluster of regular 'consumer' PCs. The wording of the question though means I'll need to cheat a bit and I'll suggest a steam machine.

Why?

\n\n

Most modern consoles are x86 based, with laptop class video. They are locked down though there's projects to try to get xbox360 and ps4 running linux.

\n\n

Many of them have nice small form factors (the 5x5 and NUC form factors would be a good starting point). They have reasonable compute power, and in most cases, nuc class machines compare favourably in price to modern consoles. If you standardise on one model, you can stack em. If you need more powerful machines or a supported OS 5 or 10 years down the road, its a common ISA likely to have support.

\n\n

Unlike a traditional console, its unlikely someone will take away your ability to run your own OS on it.

I recently built a new computer, and I'm having some issues (I think).

\n\n

Here's my gear

\n\n

Case: Phanteks Enthoo Evolv ATX

\n\n

Case Accessory: Phanteks fan hub

\n\n

Mobo: Asus Maximus VIII Hero

\n\n

CPU Cooler: Corsair Hydro Series H110i GTX

\n\n

My issue is that the instructions that come with the Phanteks case is pretty lacking on instructions for the fan hub on the back. I've read conflicting information on how to connect these devices, and I figured I'd ask here to make sure I actually did it correctly.

\n\n

My problem is that right now, the fans all stay 100% all the time. It's pretty loud, and it's possible that that's the way it's supposed to be, but I hope not. To be clear, the case fans appear to be the culprits.

\n\n

Here's how I have everything set up:

\n\n

H110i GTX\n | \n |two fan cables\n ------------------------>both fans\n |\n |water pump\n ------------------------>CPU_FAN\n |\n |data cable\n ------------------------>USB 2.0

\n\n

Phanteks fan hub\n | \n |CPU_FAN\n ------------------------>CPU_OPT\n |\n |Sata power\n ------------------------>Sata power\n |\n |3 x 4 pin fans\n ------------------------>3 Case fans\n

\n\n

The real confusion here is caused by the fact that the Phanteks case instructions say to connect their fan hub to the cpu_fan, but so does the H110i. From googling around, I found some people that had done it this way, but man, this thing is loud. Any advice?

\n\n
\n\n

EDIT 1

\n\n

Another thing I should mention. I'm using the AI Suite 3 software that came with the mobo. It's supposed to let you control the case fan speeds. When I have the fan hub connected to CPU_OPT, it's not showing any case fans in the software. If I connect CPU_OPT to any other fan connection on the mobo, then it shows up, but it still won't let me change any values.

\n\n
\n\n

EDIT 2

\n\n

After a little more research, I found out that the AI Suite 3 software won't have any control over your fans if you don't set the fan mode to PWM in the bios. I went into the bios, and now it controls the fans. The only issue now is that the case fans aren't turning on at all. I'm wondering if the temperature just isn't high enough, and they'll turn on once it's higher. If it turns on when the heat is higher, or if it doesn't turn on, I'll report back here.

\n", "Title": "How do I use the Phanteks fan hub with Corsair H110i GTX", "Tags": "|pc|windows|case|fan-controller|", "Answer": "

I'm not sure why I didn't find this solution a little faster, I guess I was just googling the wrong thing. The phantek hub needs to be plugged into a fan connection on the mobo, but not the CPU_OPT.

\n\n

Then, in the bios, you need to allow your fans to be controlled by something other than the bios.

After that, everything worked fine.

I consider buying a new desktop computer and I work on academic MIP optimization problems with Gurobi.

\n\n

I know that GPUs cannot be leveraged by MIP solvers, so my question rather concerns the choice of the CPU (and possible related configuration matters).

\n\n

Do you have any recommendation for a CPU fitting in a standard desktop computer (=available at computer retail stores) which purpose is primarily to solve MIP problems?

\n", "Title": "Is there a CPU particularly well suited for solving MIPs with Gurobi?", "Tags": "|processor|", "Answer": "

I have to admit, I had to educate myself about Gurobi.

\n\n

It looks like it is a software suite for linear optimization problems. It also seems, it is a regular one, i.e. with \"simple\" C++ and R sequential implementations.

\n\n

For that, any CPU in your budget will do. You should just try - within your budget limits - get the best clock/cache/cores combination. An AVX512 capable CPU seems to make sense.

\n\n

But let me offer an extended perspective on this.

\n\n

If performance is your main concern, you should have a look at GPU computing. As for GPU accelerated solvers, see e.g. https://developer.nvidia.com/amgx, which gives promising speedups of a factor of 10 within your reach.

\n\n

Maybe, spend only reasonable money on an average CPU. If you get the Gurobi vendor to support AmgX, you can buy also a reasonable CUDA-capable GPU and still have speedup by a factor of 10, which would not be possible by any economically feasible CPU.

I am about to purchase a Samsung 950 Pro PCIe SSD. I have a MSI 970A motherboard. I am wondering if I can insert the 950 pro stick directly into one of the x16 slots. I read online that PCIe slots are backwards compatible (so the x4 should work in a x16).

\n\n

Is this possible? Do I need a converter?

\n\n

Also, don't have a M.2 slot on my motherboard. I noticed I have PCIe2.0 slots, not 3.0 slots. Will my SSD still work?

\n", "Title": "Can I use my Samsung 950 pro PCIe SSD directly into my x16 slot?", "Tags": "|ssd|pcie|", "Answer": "

The linked drive may use a PCIe interface, but it not a PCIe form factor card. It is an M.2 form factor device and requires an M.2 slot. Without some sort of adapter, it will not work in your M.2-lacking motherboard.

\n\n

The M.2 form factor is designed to connect to multiple interfaces - SATA and PCIe - over the same physical connector. Depending on the capabilities of the connector and device, they're keyed differently to prevent you from attempting to connect incompatible devices (a PCIe-only device in a SATA-only M.2 port, for instance).

\n\n

The adapter you linked should do the job. As far as PCIe 2.0 vs. PCIe 3.0 goes, PCIe 3.0 devices are backwards compatible, they'll just run slower.

\n\n

As far as lane count goes, you can use a card that demands fewer lanes (4x vs 16x) in a slot with more lanes; the other pins aren't on the card, and therefore do nothing. Going the other direction requires paying more attention. Some cards need the bandwidth of all the lanes they're spec'd for, and some boards have things like 8x electrical slots in 16x mechanical slots for security/fit purposes (there are missing pins on the board end).

Building on the previous project of autonomic robot cars, controlled by a Raspberry Pi + BrickPi, delivering packages, we want to use (indoor) quadcopter drones for similar purposes.

\n\n

Since this educational project accounts for the bachelor dissertation of computer scientists, the drone must be programmable (e.g. given some sequence of coordinates or actions, the drone must be able to execute them) or it must be able to write a program to interactively steer the drone. The drone must also have a camera and be able to send the camera stream over WiFi/Bluetooth/... to a separate PC. This PC processes the stream and decides on the steering of the drone based on for instance the content of the images. Note that there are drones who can only store the camera stream internally and others who can send the camera stream to for instance a smartphone. The last functionality is called FPV (First Person View).

\n\n

Furthermore, the drones should ideally contain a gyroscope and accelerometer, of which the sensor values can be used in a PID controller (on the drone itself or on a separate PC).

\n\n

It would be nice (but is no requirement) to attach an electromagnet underneath the drone to attach and detach small objects.

\n\n

With regard to battery life, we aim for at least 10 min.

\n\n

The drones will be used for multiple course years. Therefore, we would like the separate components to last as long as possible and be resistant to crashes. For instance, brushed motors will need to be replaced after a couple of hours of flight, so we rather avoid these (if possible for the given budget).

\n\n

Finally, since there are probably dozens of drones these days which match the previous requirements, price is also important: below $100 (we will buy multiple drones so it would be nice if a batch of drones drops the price).

This does not answer your Question directly, but provides another approch:
\nI would keep the current device and go with a solution wich cuts the 24/7 charge to some hours per day. This stops the overheating and you do not need to buy a new tablet.
\nTo do this I would buy a time switch, which is a device that switches a socket on and off based on the times you set on the device. This way you can keep all devices plugged in and the device disables the power source without further do.
\nTo have this work perfectly you have to find a time span which holds your charge at your desired level across all devices, as an example 3 hours loading, 3 hours on battery should keep your devices over critical battery levels. However if the power consume across all devices is to far part you should consider using a second time switch for this device/s.
\nI would group the devices based on battery capacity and charging speed and aim to keep the battery level between 20-80%. Also note that the Li-Ion battery does not charge in a linear way and significantly charges slower from about 80% charge level.

I am currently preparing a configuration for my next PC and, although I know enough to chose almost all the components myself, I really have poor knowledge when it comes to motherboards. I really can't tell if a motherboard is a good one or a bad one, if it will suit my needs and which chipsets are best.

\n

My configuration :

\n
\n

CPU : Intel Core i7-4790K (4.0 GHz)

\n

GPU : Asus GeForce GTX 960 STRIX DirectCU II, 4 Gb

\n

RAM : 2x4Gb DDR3-1866 HyperX Fury, Cas10

\n

One 250Gb SSD

\n

One 1Tb HDD

\n
\n

(theses are the informations I think are needed, if you need to know what other components I have chosen, ask in the comments and I will update this question)

\n

Requirements & additional info :

\n\n

As I am getting an overclockable CPU I read - but am unsure if this is true - I will need a Z97 chipset if I want to exploit my CPU to the max, and that Z97 is also one of the best chipsets available for a configuration with recent components. If Z97 isn't required or specially better than other chipsets I have no idea which one I should get.

\n

Motherboards I consider buying

\n

Obviously I have already done some research and there are 2 motherboards that caught my attention :

\n\n

This one has very good reviews but I wonder if it is not a bit "cheap" (in both meanings) and if it will be sufficient for my configuration

\n\n

I thought is was a good idea to get a motherboard from the same constructor as my GPU (correct me if this is a stupid thought) and this one seems pretty good. But here I am wondering if I really need a motherboard at this price if some cheaper ones like the MSI above can do the job.

\n
\n

So here are all the informations. What motherboard would you buy to suit this configuration and these requirement best ?

\n", "Title": "ATX 1150 Intel-compatible motherboard under $110 for gaming / graphic design PC", "Tags": "|motherboard|", "Answer": "

As Cfinley noted, there is no benefit to matching GPU and motherboard manufacturer parts. Since you were looking at MSI and ASUS boards, I specifically looked at those two manufacturers. I think the ASUS Z97-E would meet everything you are looking for, remain under your budget (currently has a mail-in rebate as well), and be a bit more future-proof than the ASUS Z97-P you had found as it also includes USB 3.1. Also, the motherboard is black with white lettering and gold/yellow trim pieces.

\n\n

Heres the direct link to it on Newegg:\nhttp://www.newegg.com/Product/Product.aspx?Item=N82E16813132512

\n\n

Worth mentioning, there are boards with more features such as additional PCIe slots, more USB 3.0 ports, and better onboard audio available for a little more ($140+). If you want to go this route there are several decent options from MSI, Gigabyte, Asus, and ASRock available. However, since you mentioned you only plan on having GPU, you could get a PCIe sound card for much better audio whenever your budget allows for it in the future.

I think that to really monitor our workers' bandwidth consumption and access filters (e.g., website blocking) we need to have firewall equipment because the normal firewall on the computer itself (i.e., Windows firewall) is really not that helpful in our situation.

\n\n

Do I need to use firewall equipment that will cost us a lot of money or still use the dedicated firewall that the OS provides? Or will the PC-to-firewall conversion will do?

\n\n

And how is PC-to-firewall different from firewall equipment and Windows firewall?

\n\n

Edit:

\n\n\n", "Title": "Firewall equipment to prevent/monitor bandwidth consumption and set user access filters", "Tags": "|networking|firewall|", "Answer": "

I am addressing only this part of the question:

\n\n

And how is PC-to-firewall different from firewall equipment and Windows firewall?

\n\n

A hardware firewall offloads the work from the general purpose CPU that windows uses to a CPU that is specifically designed for processing large volumes of network traffic fast.

\n\n

Windows firewall can block individual websites based on IP, but does not do SPI. Also with as much as people encrypt these days SPI can not inspect much of the traffic without SSL terminator.

\n\n

If you buy software for each PC many of the functions of a hardware solution can be emulated locally, but then each PC has to have faster hardware to accommodate the addition work load. Also nasty root kits maybe able to hide from PC only solutions.

\n\n

Think about it this way, a hardware solution is like going to a gourmet cake shop and buying a cake. Only the best ingredients were purchased and a master cake chief, or whatever they are called, monitored the whole process. They used all the correct tools, baked and baked it to perfection.

\n\n

The point is you get to enjoy the cake with no effort on your part.

\n\n

The software solution is like making the cake yourself. You go to your local store buy all the ingredients took them home. Now you will use whatever tools you have on hand to mix them together and bake. You most likely use inferior ingredients and poor tools and the end result maybe just ok. Then you still have to do the dishes, and throw away the rubbish.

\n\n

When you are buying a hardware firewall, the vendor has (in an ideal world) hired a security experts to test the firewall and verify it has no known vulnerabilities. Most of them update themselves and require very little hands on once they are properly configured. The vendor assembled all the pieces for you and gave it to you in a convenient package. The will also for a fee have people on staff to help you configure it or configure it for you depending on the contract you sign and the fee you pay.

\n\n

In a software solution each part of it is like an ingredient that goes into a cake. Each piece has to be individual managed, configured, and updated. Just like our cake one bad ingredient spoils the whole thing. The foundation is the OS which has to be kept current. Then you have your basic firewall which again has to be configured and maintained. Then the SPI package, antivirus, anti-malware, and etc.

\n\n

Each packages has rules that need updating and the software itself has to be kept up to date. However, instead of being sad you made a bad cake, you company is the news for the next major data breach, and now you have to spend 10's of thousand cleaning up the mess.

\n\n

I am not saying rolling your own solution is impossible or undesirable I am only saying you need to be prepared to do all the work yourself and initially it will definitely cost more money especially in hours of labor.

Okay, the Red Pro will be much durable versus the Red. Why?

The i5 6300HQ is a good CPU for the programs you use.

The advantages of hyper threading are explained well here (Visual Studio is mentioned).

To summarize the link above:

\n

Hyper threading is useful if you are using your machine for software development (as in your case) because current IDEs are optimised to take advantage of the multiple threads. This speeds up development. Visual Studio is a program that does this.

However, when it comes to executing the program that you are actually coding, hyper threading does not really help unless you are developing an application that takes advantage of multiple threads.

Most folks report that its comfortable, but you may need to check the cables you need. Since its IR, if you pick up a second unit, you can use the second headset with the same transmitter (which is handy for movies).

The display is a QHD IPS panel, though it's somewhat dim, measured at less than 300 cd/m^2 by this review, because it's a matte (non-reflective) panel, it should be usable outdoors.

\n

The CPU is the i7 7700HQ (2.2 GHz, 2.8 Turbo), the newest generation high performance quad core. While not top of the line, the only faster CPUs are the same, with only a few hundred MHz extra clock speed.

\n

The base model also comes with 16 GB DDR4 2400, a 512 GB M.2 SSD and the GTX 1060 GPU (1280 CUDA cores, 6 GB VRAM), which is a desktop class GPU: Even at maximum detail settings and native resolution, it should be able to maintain more than 30 FPS for today's AAA games.

\n

Unfortunately, there is no Ethernet port, so the laptop relies on 802.11 ac WiFi, though you could use a USB to LAN adaptor. There are three USB 3.0 (Type A) and one USB 3.1 (type C) ports, as well as HDMI 2.0, mini-DP, Headphone-out jack and a SD card reader. I don't believe it comes with an optical drive

I'm considering updating my monitor setup to a quad display workstation sometime soon, but I'm having trouble finding a monitor that fits my list of requirements...prepare yourself (in no particular order):

\n\n\n\n

These monitors will be used solely as a productivity boost. No gaming at all, so I don't need any gaming related monitor features. They will be used for some graphics work, but nothing serious so maximum colour quality isn't a must, just something \"decent\".

\n\n

I'm not too bothered about them having mounting plate points, but I suppose it would be a nice bonus. If they did have them I would probably put together a DIY stand at some point, but for now I definitely want them to all stand and rotate independently.

\n\n

After all that, I'm not really sure where to cap the cost. The lower the cost the better. I'll judge how realistic this ideal setup is when I know how much it would cost me!

\n\n

Any suggestions? I'm in the UK, so I'd prefer local options to having to order stuff from abroad. (Bonus points if you can supply a purchase link/cost.)

One of the few places where you can't go wrong with dell is their monitors. I don't own this specific model, but I can attest to them having excellent build quality

The Dell 2417H is probably what you should be looking at, no pun intended. Dell lists them at GBP 245 on their website (with a discount), but you probably can comparison shop.

These are really small bezels, IPS (and which ensures awesome viewing angles and great colour quality). They're 1080p.

It does HDMI and DP only (but there's simple converters for DVI, or even VGA should the need arise).

Dell probably makes the best monitor stands on the market. They sell a dual monitor stand if that's what floats your boat. The standard stands give you height, tilt, and rotation adjustments, though this seems a new design. If you want to vesa mount them, they're compatible with the 100mm standard.

Alternatively, if you have a printer with ethernet access, you can get a wireless access point and set it to bridge mode. After this access point is configured in bridge mode you'll be able to plug an ethernet cable between your printer and the access point.

My company is going to buy a work laptop for me (since I've been using my own for a while), and they are going to let me select it. I don't know exactly what my price-range is, since they wouldn't actually give me a hard-limit when I asked. However, they implied that they would be willing to spend somewhere in the range of $1,000 USD. I will probably select some slightly cheaper and some slightly more expensive ones and let them pick between these.

\n

This laptop will primarily be used for firmware and software development and TwinCAT, as well as general day-to-day office stuff. (Excel, word, emails, etc.) Sometimes I will compile very large projects, or have multiple instances of Visual Studio or a similar IDE open at a time (which isn't all that much, given Visual Studio's system requirements). Beyond that, I don't do anything particularly demanding. I'd like it to boot quickly, so an SSD is a must.

The best notebook I could find in this price-range with your requirements is probably the Lenovo 700Y (17-inch) series. While I don't own, it seems to fit your requirements quite well, as a medium- to high-end gamer laptop.
\nLenovo; NotebookCheck

\n\n
\n\n

Now let's go through the list of your requirements, shall we?

\n\n
\n

As I said, an SSD is a must. [...], so we'll say atleast 250 GB.\n Obviously, more would be nice, though it's not necessary.

\n
\n\n

According to Lenovo's website there are options for 256GB or 512GB SSD and for 1TB HDD with 128GB SSD, so you're covered here.

\n\n
\n

A 6th-gen intel quad-core CPU. I'd like an I7 or higher, but I could\n settle for an i5, provided it was still new, quad-core, and fairly\n powerful.

\n
\n\n

The Y700 series only runs 45W Intel Core i-s, which are all (powerful) quad-core CPUs based on Skylake architecture. More concretely chances are you will be getting in i7-6700HQ or an i5-6300HQ (rarer).

\n\n
\n

I don't do anything demanding on the GPU, so as long as I can plug an\n external 1080p monitor into it, that's good enough for me. Bonus\n points if I can plug a second one in. (Though I might need a docking\n station at that point)

\n
\n\n

You can at least plug-in one monitor via HDMI and can maybe connect a second via wireless Miracast, which the laptop should support.

\n\n
\n

I don't need an insane amount of RAM. [...] So 8\n GB would probably be enough. (Although I'm certainly not against\n having more)

\n
\n\n

The Y700 series has at least 8GB of RAM and you can also find models with 16GB.

\n\n
\n

This probably goes without saying, but it should have an 1/8th inch\n headphone output and several USB 3 outputs.

\n
\n\n

It has that headphone output and two USB-3.0 ports and one USB-2.0 port. You may want to consider buying an USB-3.0 hub if you need more. (These numbers are fairly common for laptops nowadays sadly). The HW recommendation for this can be found here.

\n\n
\n\n

Now for your preferences:

\n\n
\n

Support for a docking station, if I want to upgrade peripherals down\n the road.

\n
\n\n

Sadly there seems to be no proprietary connector for this model, however standard USB 3.0 docking stations probably can do the trick here.

\n\n
\n

[...]An\n onboard ethernet cable would be really really nice. I could use an\n adaptor or a docking station, but using onboard ethernet would be a\n lot more convenient.

\n
\n\n

Again, sadly it looks like Ethernet on the laptop seems to be less of a thing nowadays than it used to be (due to the improved WLAN technology), but you can still get yourself a small little USB-3.0-Ethernet connector (Anker also has those).

\n\n
\n

I'm not really a laptop connisuier, so there are a lot of things that\n I either don't really care about or don't know how to quantifiy. For\n example, I have no idea what a good-battery life would be. I'd like a\n good battery-life, but I don't commute, or have any reason to need a\n really good one. I also couldn't tell a good one from a bad one.

\n
\n\n

Lenovo claims 4-5 hours for this one, but chances are you'll have to live with 2-3 hours there if you actually do stuff with it.

\n\n
\n

I'm also not super picky when it comes to things like screen size or\n weight. (Also don't know how to quantify) I don't want something on\n either extreme (Such as a chromebook or a giant luggable). A 1080p\n display (or higher if I can get it at this price) would be preferred.

\n
\n\n

There are variants of the Y700 series for 15\" and for 17\" (this answer is about the 17\" ones), but at least the 17\" ones all do feature 1080p screens.

\n\n
\n

I will be able to use the laptop on my own time, so a gpu (or\n integrated graphics) strong enough for very light gaming would be\n nice. I already have a computer that can handle pretty much any game,\n so this is certainly not a requirement.

\n
\n\n

The Y700s are originally intended as gamer laptops, so this should be not so much of a problem.

\n\n
\n

Good linux support would also be a plus.

\n
\n\n

I don't think it has extraordinary Linux support, but it should do the job.

\n\n
\n\n

Finally for your neutral points:

\n\n
\n

While looking around on my own, I found that lot's of newer laptops in\n this price range have touchscreens. I am almost completely neutral on\n a touchscreen. If it could be cheaper without, I'd go with the cheaper\n one. If they're the same price, I guess I'd go for the touchscreen. I\n probably wouldn't end up using it very much though.

\n
\n\n

The Y700 series does not feature touch-screens, as a gaming laptop series.

\n\n
\n

I don't really care which version of windows it comes with. It would\n be nice if it comes with 7 already installed, but if it comes with 8\n or 10, I'll just reinstall 7 anyway. (I already have a license and a\n CD and all that)

\n
\n\n

It comes with Windows 10 64-bit pre-installed.

\n\n
\n

I don't really care about an optical drive (or lack thereof)

\n
\n\n

I couldn't exactly tell, but at least some models don't feature optical drives.

I have pretty much no experience or knowledge about modern hardware, other than the past couple hours I've spent researching it.

\n\n

I built a rig online here:\nhttp://pcpartpicker.com/list/BwmgLD

\n\n

I was hoping for any advice/recommendations. Anything that I'm paying too much for, that I wouldn't notice a difference with a cheaper option. Anything that I'm potentially bottlenecking my setup by going too cheap. Any brand that I chose that is know for being unreliable. Etc.

\n\n

There are a couple notes on compatibility shown, it seems like they wouldn't be problems for me but if you think it will let me know.

I especially know nothing about what makes a case good or bad, and what is necessary with the power supply.

Gaming generally benefits from faster single core but VM benefits from multiple cores. If you are planning to run less than 4 ish VMs then the i5 6500K will be a better choice (of course you will have to change your motherboard as well).

\n\n

That SSD is cheap, a little too cheap. Go with some reputable brand to get performance and quality (such as Samsung, AData, Patriot, Sandisk, etc.). You could also take a look at having a smaller SSD for boot and a hard drive for your games and other files.

\n\n

Your motherboard comes with an ethernet port so unless you are going to use multiple IPs or aggregate the connection you don't need the ethernet card. Your motherboard is a mATX motherboard, which is smaller than the regular ATX size. This fits in your case but you lose the extra PCIe ports you could get from an ATX board.

\n\n

You might also want to take a look at a CPU cooler like the Cooler Master Hyper 212 Evo (bare minimum) because the CPU runs quite hot and the stock cooler isn't that great.

I myself have a Samsung EVO and it works flawlessly in my PC. In my PS4... well I haven't tried it in there.

On the other hand, this gentlemen here saw a large difference in speed with some games (check out the tables he created with load time comparisons).

My primary desktop PC is due for a refresh.

\n\n

I have always built my own, but I might have reached the point where it's worth the extra ~$100 to buy a pre-built machine.

\n\n

As Peter noted, keys to silence are, foremost, to keep fans off or slow. This system is built around a 65W CPU, and I haven't (yet) put a power-hungry GPU in there (I realized I can run 4k off the MB's HDMI). So the PSU and CPU fans aren't going crazy, I put a quiet spinning disk inside along with the primary SSD, and it's just quiet all the time! (Except, of course, when I'm using the optical drive.)

While purchasing two cards may seem gnarly, it really wouldn't be better than a single 1080.

\n\n

First, you won't have to fuss around with getting SLI to work properly. Not that its a massive pain, but it is a pain.

\n\n

Second, some games do not even support SLI properly. Now this may not happen often, but imagine your shock when your $1000+ GPU setup won't play nice with certain games.

Fourth, resale value. Not that you'll want to sell, but this is still something to think about.

To answer your question about recording, recent NVidia cards have a feature called ShadowPlay that can record games using a chip in the card independently of the CPU and the rest of the GPU, meaning next to no performance impact on games and computer usage. ShadowPlay is capable of both recording and streaming in 1080P at 60 FPS.

\n\n

The limiting factor for recording on a 970 is more likely to be your HDD or SSD. It's strongly recommended to record to a second HDD, apart from the disk where Windows and the game is installed, to avoid the disk from being overloaded.

\n\n

However, in response to whether the 970 is good enough; the GTX 1060 will be released soon (sources say the 14th of July) which will most likely offer performance improvements over the 970. I strongly recommend waiting until then before making a decision and buying the 970.

\n\n

As to whether the 970 is powerful enough to run the latest games at ultra settings, that's a matter of the game. Games like The Witcher 3 are very graphically intensive and can't be run with high FPS on the 970.

\n\n

Without knowing the specific games you're interested in playing, it's best to look up user experiences for the card and game you're interested in.

There are several things to consider when purchasing a PSU, but here are the most important:

\n\n\n\n

There are obviously aesthetic requirements as well, like whether it's modular, whether the color will match your build, and sometimes special lighting.

\n\n

That said, picking a PSU is one of the easiest components to choose. Here's the one I went with on my recent build, with a 6700k and a 1070: EVGA SuperNOVA 750 B1 80+ BRONZE, 750W. This unit has more wattage than I currently need but it leaves room for upgrades in the future.

\n\n

EVGA is a reputable brand, this unit has great reviews, and it's relatively cheap. My only complaint with it is the mesh surrounding the cables don't completely block the colors of the cables inside, but that's not noticeable once it's in the case.

\n\n

If money isn't a concern, go with something fully modular with lots of plugs, and higher power efficiency, like this: EVGA SuperNOVA 750 G2 80+ GOLD.

I've started using Cycles Render in Blender for a specific project. I've set up CUDA on my Linux machine to enable rendering with the GPU however discovered that my graphics card, an old GeForce GT 520, does GPU rendering much more slowly than the render with the CPU (Intel\u00ae Core\u2122 i7-2600K CPU @ 3.40GHz).

I have extensive experience with Blender and cycles.

\n\n

The 750Ti is about 20% faster than your CPU.\nThe 950 is about 100% faster than your CPU. (i.e. double the performance)

\n\n

But currently GPUs render fur a lot slower than CPU, so take that into account if you work with a lot of fur.

\n\n

With the CPU, you get the advantage of having access to all your system RAM (8GB, 16GB, etc). Whereas if you render with a 2GB GPU, it will not render a complex scene that requires more than 2GB RAM.

\n\n

I would consider the 950, but not the 750Ti.

You are looking for a ATX case. I have a few suggestions for you. Consider the LIAN LI PC-A05FNB or the Antec Sonata Series SOLO II.

\n\n

For comparision I have listed the Fractal Design Define R5, which is my favorite case. However, it is too large for your requirements (\"but dont to be very big outside\"). It's dimensions are 17.76\" x 9.13\" x 20.51\". You seem to want something smaller.

\n\n

Three smaller cases are listed below. I only have experience with the Antec Sonata Series SOLO II. It's an older design, and it is missing some of the touches found in the R5, but it is a good quality case and it seems to be about the size you are seeking.

\n\n

However, the LIAN LI PC-A05FNB has very positive reviews. It is worth considering.

\n\n

The very smallest ATX case I know is the Cooler Master Elite 361. I have not used it. I think it is a older design, also probably lacking the modern features of the R5.

Not sure if this is the best forum for this. If it is not, can you point me in the general direction of the best one?

\n\n

I would like to play a video game that needs 1GB of dedicated RAM to the graphics card. When I use the \"Can I run it\" site, it tells me that there is only 32 MB of dedicated graphics RAM. When I run the game it is unbearably choppy and I am not able to play it.

\n\n

I have included Device Manager and dxdiag screenshots. The Display screenshot says that I have just about 4GB of RAM for graphics. I have checked all the drivers, they are up to date. I have attempted to go in to the BIOS and change the amount, as recommended by some Google searchage, but there is no option in there that I can find. I've selected every single option I can, just in case it's lurking somewhere I wouldn't expect to find it. Is there anything else that I can do, other than replacing the card, to satisfy the game requirements?

That graphics card is horribly underpowered for any modern game. I would advise you to get a newer/better one (such as a 750Ti). It would be better to just plug the monitor into the mainboard graphics plug, as even intel's integrated GPU will outperform the 8500 GT and might be able to play some modern games somewhat smoothly.

I have single gtx 760 3gb and still have room for another gpu. Should I go for a newer like 970 or 980 or get SLI?\nHow better is 980 from 760 sli?

\n", "Title": "GTX 760 SLI worth it?", "Tags": "|graphics-cards|", "Answer": "

Get something newer. Your card has 192-bit Memory Interface Width, and a memory bus that slow is not going to handle 3gb's of memory very efficiently, even with a single card. You would be in a much better position with a single 970 or 980. While the amount of VRAM might be greater with the two 760's, you won't see better performance than you would out of a single 970 or 980. And you'll also have to deal with the first four problems I list in this answer here. Let me quote myself:

\n
\n

First, you won't have to fuss around with getting SLI to work properly. Not that its a massive pain, but it is a pain.

\n

Second, some games do not even support SLI properly. Now this may not happen often, but imagine your shock when your $1000+ GPU setup won't play nice with certain games. (Don't get me wrong, I know most games support SLI, but this doesn't change the fact that there are some compatibility issues with certain games...)

\n

Third, power consumption. It may not be a huge issue, but its another issue to stack on-top of the other issues that come with running two cards. (~150 watts per 970, vs ~250 for a single 1080)

\n

Fourth, resale value. Not that you'll want to sell, but this is still something to think about.

\n
\n

All of these issues apply directly to your situation as well. Except the power consumption would be slightly different for 760's vs 970's; but the same concept applies, you'll be drawing significantly more power.

\n

You would also have to find a 760 3gb card, which would be tough to get new, so you would be stuck with used or refurb models off of eBay.

\n

So all in all? Don't go for SLI, instead of searching for the same card, save your time, put more money up front and get yourself a GTX 970 or 980 (go Ti if you can!).

As long as you are happy with 80+ Platinum and the power envelope, there have been no significant improvements in power supply technology over the past few years. A quality PSU is a quality PSU. If it's been sat in a box, it won't have degraded, as it would have under use (PSU calculators use a 10% per year worst case in their analysis, generally you get better than that though).

The bottom line with a PSU is how much power it can provide, and how efficiently it provides it. The AX line was top of Corsairs range, just as the AXi line is now.

I am trying to create a NAS but I want to run my own software on it. I want to be able to download data around 20MB/s over WiFi from the system.

\n\n

I used a raspi and created a prototype, but as it uses a single bus it is not able to transfer data from the HDD to the user at the rates I am talking about. Anybody know any build that suits this? Looking for suggestions.

\n\n
    \n
  1. Budget – around USD 300 - 400
  2. \n
  3. Size requirements – as small as possible
  4. \n
  5. Operating conditions – Will be deployed in my van: take impacts into consideration, I am planning to devise a case that can solve this issue. Needs heat dissipation solution as my van is not air conditioned.
  6. \n
  7. Desired software you want to run on it – web server running on Node.JS
  8. \n
  9. Storage media – 2TB HDD (as of now I use a 1TB external)
  10. \n
  11. Power solution – need a powerbackup that can last for one hour
  12. \n
  13. I need good network adapters and USB ports that won't hinder my data streaming.

So if you are looking for what I think you are looking for I would suggest you look for a cheap server on ebay or in a small form factor case for around 80$ like this one:http://www.ebay.com/itm/FAST-DELL-DUAL-CORE-3-4-GHZ-DESKTOP-COMPUTER-PC-4GB-RAM-Wifi-WINDOWS-7-PRO-/262152856157?hash=item3d0987225d:g:AdoAAOSwYmZXI2bs

\n\n

This is very small comes with windows 7 and you can configure it with a 2tb hard drive for 100$ then for an os you can use windows 7 or you can use free nas which is an amazing server software which I have used myself and if you want to bring the 80$ down you can look for one with no os and just buy the hard drive and slip it in and put free nas on it. Now I dont know if you need a nice router but if you do I suggest this: http://www.officedepot.com/a/products/555607/Belkin-N300-Wireless-Router/?cm_mmc=PLA--Google--Printers_Scanners_Faxes-_-555607-VQ6-47886868676-VQ16-c-VQ17-pla-VQ18-online-VQ19-555607-VQ20-76926630596-VQ21--VQ22-177839036-VQ27-9203161796&gclid=CILM5pvuh84CFQ6EaQodFvsHxw

\n\n

I have this hooked up to my modem and can get around 100mbps download speed

\n\n

Speaking of modems if you want a nice one of those I would suggest this: ARRIS / Motorola SurfBoard SB6183 DOCSIS 3.0 Cable Modem \u2013 600 MHz Dual-Thread Processor

I am looking for a graphics card that can run Starcraft II at 1080p and 60 fps. I know that it isn't a super graphics heavy game and am ideally looking for something under $100. I would like something that has linux support as well but most major graphics card manufacturers have that.

If you have not already purchased anything, it is entirely possible for an APU to provide you with the processing AND graphics power you need to run the game well. Given that StarCraft II is not highly threaded, but that unfortunately Intel refuses to put any worthy GPU on anything below an i5, I recommend something like the A10-7890K, which at ~150 represents a $75 CPU combined with a $75 GPU and pretty much performs like it, too. Just be sure to pair it with 2133 or 2400mhz RAM.

\n\n

Alternatively, get whatever CPU you want and pair it with a GPU like the R7 250X or GTX 750; either one is powerful enough for SCII in spades.

The 480 is not a bad choice for that rig especially that the pc is not meant for heavy gaming. But if you wanted a little more performance you could also go Nvidia and get the new GTX 1060 which performs just a littlebit better than the 480 or if you wanted outstanding performance for the same ~$250 price point you could also get the GTX 970 which would be a really good pair for your CPU, but keep in mind, that is now a generation behind the latest GPUs from Nvidia.

If you are running 1080p there are card choices for you to play overwatch near max settings with a GPU around $100.

\n\n

I recommend you continue saving to at least get an AMD RX 480 for about $200 dollars and that will play EPIC settings which is maxed settings.

\n\n

But lets say you couldn't spend any more than $150, then I would recommend GTX 950. Here is one on amazon for less than $150 - MSI GTX 950 $132.99.

\n\n

But lets say you couldn't spend any more than $125, then I would recommend a, like the others an GTX 660ti.

\n\n

But overall, it seems like the GTX 950 is my overall recommended card in your case.

\n\n

Edited: after seeing your using a intel i5, you should be fine to hit higher frames these cards are intended to hit. If you can't hit the desired frames, then you might want to look into safety overclocking your CPU and GPU.

\n\n

Newest Edit\nThe NVIDIA GTX 1060 just came out for MSRP $250, that and the AMD RX 480, destroys current 1080p games! IMPORTANT: in order to get any of these new cards listed for their MSRP, you will have to wait for less demand and more supply. Cause right now people are buying these cards for more than what they're supposed to cost. Or buy them from a BestBuy or something. Usually, BestBuy doesn't push their prices up based on supply and demand.

\n\n

As for windows G, im not sure what that is, but i know people who use twitch that stream with twitch has that equal or more powerful cards listed in this post with no problems at all.

I'm currently running on a core i5-4460 CPU @ 3.20GHz on a 1150 LGA socket (Haswell). I need to upgrade to an i7 but I'm unsure on what one to go for, it needs to be faster for compiling code (using the machine for software development) - I'm aware a lot is handled by the SSD, thus I'll be installing 2 in raid 0, but the user has specifically requested an i7. Budget of between \u00a3200 and \u00a3350. Also, suggestions of trusted supplier would be appreciated (I'm in the UK).

\n", "Title": "Which i7 processor should I buy for compiling code?", "Tags": "|processor|", "Answer": "

Given that compiling is a thread-heavy job, your user is best off with the i7 that most cheaply gets them the most threads. Given that all i7 CPUs on the 1150 socket feature 8 threads, that means simply getting them the cheapest i7 you can put in that socket, which would likely be the Intel Core i7-4770S or Intel Core i7-4790.

\n\n

As an aside, Xeon processors are extremely similar to i7 CPUs and fit on this socket. In addition, they support ECC RAM, which is a feature many compiling rigs benefit from due to the high memory usage and long compile times they can undergo. In addition, some Xeons, like the Intel Xeon E3-1275 V3, currently offer higher performance and lower cost than some of those i7s previously mentioned, and would thus be a better fit. Keep in mind to utilize the ECC feature of Xeon processors, the motherboard and RAM must also support ECC.

A week ago I built my new pc. The case came with 2 in-built 3-pin case fans, and my motherboard only has one 3-pin SYS-FAN connection. One case fan is in top-rear of the case, and the other fan at the bottom-front.

There are two possibilities for the fan on the front:

\n\n
    \n
  1. I can connect it directly to the PSU with a cable like this. The con is that the fan will always rotate at full speed. I do not know if fans are used to rotate at full speed.

Just connect it to the PSU unless the noise it makes is not acceptable. It is not bad for the fan to run at full speed all the time. The splitters will communicate the same fan speed to both fans.

Crossfire is a little more forgiving than SLI. You can crossfire these cards together, but you should be warned that doing so means being hamstrung by the maximum values of the weaker card.

\n\n

For example, you will have the computational power of two 370s (minus crossfire overhead), but you will be stuck with a maximum of 2GB of VRAM. Depending on what you are pushing through these cards, your performance could very well decrease significantly.

This question is here after I ask this one: UHD compatible Graphic Card

The thing is that I have a HTPC and would like to be able to read UHD movies (since the i3's IGP cannot). As you can see in the previous question, finding a passive GPU with UHD display is impossible for now.

I'm looking into getting a new gaming pc, but I'm not much of a hardware enthusiast. I know what kind of general specs I want to have, but when it comes to details, especially the mainboard, I'm lost with all the kinda same-y, similar price-range motherboards out there.\nHere are my current planned specs:

\n\n

-GTX 1070 (not sure which model yet, but I think that shouldn't matter for this)

\n\n

-Intel i5 6600K

\n\n

-2x8GB RAM (Model would depend on mainboard, no?)

\n\n

-3 Harddrives (2 SSD's, 1HDD) and a Blu Ray Drive

\n\n

-ATX Chassis

\n\n

further considerations:\n-I'm not likely going to get into overclocking, but I might upgrade to SLI at a distant point in the future (if that becomes more viable for gaming in the next years).

\n\n

-I'm not going to try and desperately squeeze the most bang-for-buck out of this computer, but if you recommend something overly expensive I would need good reasoning to consider it.

\n\n

-The PC is mostly going to be used for gaming, no fancy hobbies that need special considerations.

Let's start saying that your setup seems really more-than-good, even of i would go with an Intel Core i7-6700K, and 1 SSD (256GB) and 2 HDD (1TB or + each) cause today's games tent to \"eat\" many and many Gigs. \nBUT the i5 processors are a really good deal for gaming and you sure did your counts about what you need for the storage parts, those was only advices from my personal point of view.

As per your motherboard choice, i can point you here:

It has the latest chipset and it's kinda futureproof 'cause it has the 1151 CPU socket (the i7 mentioned above has the same socket) and it also supports DDR4 Ram (up to 64GB)

For the RAM choice, my advice would be:

I'm running into issues with my current laptop (an old Macbook Pro Retina) while trying to screen record graphic design tutorials so its time for an upgrade.

I don't do much video work beyond the screen recording but might want to and even Photoshop and Illustrator now has some features that utilizes the GPU so a discreet graphics card is preferred. I have a Wacom Intuos Pro that I always use when I'm at home and sometimes travel with. I'm in the market and was going to buy a new monitor for myself but its on the back burner for the moment. Probably later this year or by April of next year (Tax Return) I'll be getting a new monitor for myself to use when at home with a Wide Gamut Color Accurate Display.

\n\n

My main concerns are color accuracy, brightness, contrast, and enough specs to screen record tutorials on. Since I don't currently own a tablet I decided a 2 in 1 would be really nice to have.

\n\n

I'll be using it for Digital Painting, Retouching, Sketching, Tethered Photography. At home I can still plug it into my Intuos Pro if need be and once I get the monitor I'd plug it into that as well when at home.

My research:

\n\n

Lenovo Yoga P40

\n\n

Pros: nVidia graphics card, good price, Wacom AES with 2048 pressure levels.

\n\n

Cons: I've not been able to get an answer from Lenovo regarding colors. What little I could find has said it only covers about 65% of the sRGB spectrum though I've seen other reports claiming 75% and still some saying 95%. I don't know what's accurate. Also the Graphics Card included is not one listed on the Adobe website.

\n\n

Lenovo X1 Yoga

\n\n

Pros: Good price, Wacom AES with 2048 pressure levels, OLED

\n\n

Cons: Integrated graphics and again not sure about how much of the spectrum it covers

\n\n

Microsoft Surface Book

\n\n

Pros: PixelSense Display, nVidia Graphics Card

\n\n

Cons: for i7 much more expensive than Lenovo, n-Trig instead of Wacom with only 1024 pressure levels, not a lot of information on what that nVidia graphics card actually is

\n\n
\n\n

What 2 in 1 might you recommend? One of the above? Something I missed?\nAlso if anyone knows any model at all that has Wacom AES that stores display I'd love to hear - the X1 and P40 are too high end for retailers so I have no way to feel them first.

Update: I wasn't clear in my original post. I travel, a lot. I'm gone for weeks at a time and want a mobile solution so I can be gone even more of the year. This has me in places with little to no internet frequently.

It seems people also are trying to just give me the cheapest option. Money isn't my biggest concern. Convenience however is a big one so please don't say, well if money is no option buy a desktop, a Cintiq, and a laptop. I'm looking for a single device that can fit the vast majority of my needs.

\n\n
\n\n

My primary concerns with the aforementioned is I don't know their displays or graphics cards at all. The M500M for example in the Lenovo P40 Yoga seems to be a lower level nVidia card and its not on the Adobe website so I don't know if it will meet my expectations or if I'm wasting money.

I'm going to recommend the Lenovo Yoga P40.

Some users appear to have gotten excellent results out of ~800 machines from Dell, but again - I can't be certain which exact model to recommend.

The Yoga is the only reasonably priced, reasonably powerful option on your list. It will be a very powerful machine, is upgradeable, and does satisfy the wacom requirement. While its GPU may not yet be listed by Adobe, I have good confidence that it will work well with Adobe, since it is a professional-tier chip.

\n\n

The M500M is a mobile chip, so of course it doesn't have all the power you might expect from a standard desktop solution, but it is a midrange professional card and would represent a big step up from your current i5 integrated graphics.

Modern retail processors are all multi-cored, so my question suppose a multi-core CPU.

If so, I guess it's smart to buy Intel Core i3-6320 than i5-6500 for daily use, as the single thread score of i3-6320 is higher than i5-6500 according to PASSMARK. However, you may not tell the difference when in real situation as both CPUs are so fast for daily tasks.

  1. Programs that don't use very much CPU at all (most programs)
  2. \n
  3. Programs that use only one thread of a CPU heavily (a few programs)
  4. \n
  5. Programs that use all threads of a CPU heavily/evenly (a few programs)
  6. \n
\n\n

So what does that mean for you? It means that for everyday usage, you will see absolutely no difference between the i3 and the i5 in question. While the i3 does indeed have a higher single thread score than the i5 - and suffers from two fewer cores - it uses hyperthreading, so in fact it has four threads it can execute programs on simultaneously, the same as the i5. I'm not going to get into why hyperthreaded threads are not as desirable as fully physical threads here, but suffice it to say this is kind of like a middle ground between a true dual core and a true quad core when it comes to multithreaded performance.

\n\n

So what programs will actually see a benefit from that i3's higher single thread performance, anyway? The answer for most users is precious few. Older computer games, some parts of photo editing software performance, a few OS operations... I really can't think of anything else. There are lots of programs that are still single-threaded, it's just that most of them fall into category 1 - you won't see ANY benefit past the point of, say, a Pentium 4 @ 3.4ghz!

\n\n

On the other hand, what programs will see benefits from the full four cores of the i5? Again, the answer for most users is precious few. The OS itself sometimes uses all four threads heavily, zipping/unzipping files is often a heavily multithreaded process, and watching HTML5 video or webms can sometimes see fairly high multicore utilization, especially if more than one plays at a time... but (and this is another wrinkle to the answer) since both of these CPUs in question feature GPUs with Intel's Quicksync video encoding technology built-in, handling some of the most demanding multithread CPU work a modern user might commonly encounter, having to do with HD video playback, encoding, etc - there will be much less of a difference between the two processors than the simple multithreaded benchmark score would intuitively seem to indicate.

\n\n

The one caveat to all of this is that if you are a true multitasker - if you have more than one demanding task going at any given time - the i5 is probably going to be a better bet for you. For example, if you wanted to zip a large file while simultaneously transcoding media being cast to your TV and using a word processor on a large document - that might warrant the more powerful CPU.

\n\n

For the average daily user who simply wants to listen to music while watching a youtube video with about 20-30 chrome tabs open in the background and maybe a torrent going - both of these CPUs are huge overkill. You could step all the way down to something like an A8-7600 or a Celeron G1840 without noticing much, if any, performance degradation. In fact, for the average daily user, something like the A8-7600, which can run at a 45W TDP and which sports superior integrated graphics, is probably a much better choice than either of these CPUs, because it is more efficient and sports a more balanced design (a good mix of single-thread, multi-thread, and GPU power).

\n\n

Choosing between the two processors asked about, however, I'd have to recommend the i3-6320. It's cheaper, and since nothing else really stands out as being particularly great for the basic home user when it comes to the i5, there's no reason for me to suggest you buy it.

Of the three notebook options you've provided, I'd personally go with i3 5005u. Using cpuboss.com, it is clear that the i3 has significantly better single core and multi-core performance than the Pentium n3700. You probably won't need the extra performance for web browsing and document editing, but it will come in handy in a situation where a little more processing power is needed. Also in performance, the i3 has a higher integrated gpu perfomance than the Pentium, which should help with improving video playback (1080p @ 60fps) and multi-screen. Furthermore, Intel ark says that the i3 supports 16gb of ram compared to 8gb which the Pentium supports. This gives \"upgradability\" for the future, just in case.

I looked around on the Internet for an answer and wasn't able to find one, so I thought I'd ask it here. (3 part question)

\n\n

Let's say I have one graphics card that can run 3 screens that's also crossfire capable. If I were to use 2 way crossfire (two of the same GPU) does that mean I can now use 6 screens (three on each card)? If I can only use 3 screens, would I plug the screens into the graphics card closer to the CPU or further from the CPU. One last part to the question, do I need a crossfire bridge for the graphics cards? Somewhere I read that sometimes you don't need bridges for multiple grpahics cards (like it's integrated in the mobo or something). Thanks in advance! :D

No. The only way to use the additional 3 video outputs on the other card would be to run it without crossfiring it. You can run multiple GPUs in a computer without needing to crossfire them.

    \n
  1. If I can only use 3 screens, would I plug the screens into the graphics card closer to the CPU or further from the CPU?

It doesn't matter. AFAIK, crossfire and SLI are smart enough to recognize which card is intended as the master - that is, whichever has the video outs attached.

    \n
  1. Do I need a crossfire bridge for the graphics cards?
  2. \n
\n\n

Not for modern GPUs on modern motherboards which are crossfire certified. It may also work in other circumstances that are less well-defined, but your GPU and motherboard should not require a crossfire bridge.

\n\n

Addendum:

\n\n

I feel like noting that your CPU has its own GPU, and your motherboard has 3 or four video outs of its own. If all you are trying to do is run more than three screens, not all of which will be used for gaming, then you could run up to three screens off of this integrated GPU if you enabled it in BIOS. You would need to install Intel graphics alongside AMD's, but that should present no problem. This way, you could support up to six monitors without needing to add a second GPU.

\n\n

Additionally, you could add another small GPU with three video outs - like an R7 240 or GT 730 - which could be used alongside your other GPU systems to provide a further 3 screens - up to nine.

\n\n

NOTE: As it currently stands, your GPUs will all need to use a displayport connection for connecting a third monitor. This is something that needs to have an active adapter dongle attached to it if you will be using it to push a signal to a screen which does not support displayport (e.g. it uses VGA, DVI, or HDMI inputs exclusively).

There's a video card that I want to buy (Asus ROG STRIX 1080 GTX) that comes as a regular version (A8G, which I believe is already overclocked compared to the default OEM specs) and an overclocked version 08G. I believe both ship with an easy to use overclocking software program.

\n\n

The latter is actually only slightly more expensive in terms of MSRP. However, because of the lack of availability, it tends to be much more expensive than the A8G version.

\n\n

Is there a reason to pay the premium for the 08G or is the A8G expected to reach the same frequencies after manual overclocking without any further drawbacks?

\n", "Title": "Is there a good argument to buying the more-expensive overclocked version of a particular video/graphics card?", "Tags": "|graphics-cards|", "Answer": "

They are not expected to reach the same frequencies, though for most overclockers it is close enough that a significant price difference is not warranted.

\n\n

In silicon chip manufacturing there is a process called binning, wherein tests at the factory sort chips according to the quality of their manufacture. The highest quality chips - the highest \"binned\" examples - are the ones which will respond most positively to overclocking, because they don't skirt the QA lines on any of their specifications. Those chips are usually not simply thrown back in with the rest of the batch and sold so that some customers get lucky with OCing and others don't - the higher binned chips are used to create the higher-tier SKUs, and within those SKUs, the best of the best are used to create the OEM overclocked models. Those chips are the ones which stand the best possible chance of being monstrously good overclockers - the only pitfall some people fall into is in thinking that the factory overclock indicates the percentage by which they will beat more conventional SKUs - this not an accurate way of thinking, because sometimes OEMs are able to set factory OCs very close to the upper limit of the part's capability.

\n\n

The last thing to consider is that the OC'd models of GPU often receive some of the best addons an OEM can offer - better caps, better software, backplates, and better cooling solutions. All of that combines to add value to the more expensive models. In some cases, you can see crazy things like OC'd R9 270s outperforming R9 270Xs as a result of this.

\n\n

The thing to keep in mind when all is said and done, however is this: are you the type of person to worry over your GPU's clockspeed for several weeks, tweaking it and testing it meticulously until you have achieved the best possible result? If not, it probably makes more sense to go for the similar but cheaper model. Factory OCs on their own usually do not offer a sufficient value increase to justify the premiums they are sold at.

\n\n

I recommend the slower, cheaper version of the card unless you are very passionate about overclocking.

Your question fundamentally breaks down to which motherboard you should go with, because the motherboard will determine the CPU, GPU(s), RAM, and everything else. I'm going to recommend, therefore, that you go with a dual socket 2011 board, like this ASRock EP2C612D16C-4L SSI EEB Server Motherboard, though any other board like it would probably do as well for you.

\n\n

These boards support a LOT of PCI-E throughput - this particular model supports 3x 16x slots and 2x 8x slots, in a configuration that would allow you to run up to three double-height cards without risers, with the caveat that the top card would need to be an ITX version of whatever card you wanted - these cards are available without a huge price bump for the most of the recent Nvidia GTX lineups. Furthermore, this board supports the socket 2011 HPC Xeon CPUs, which offer extremely performative CPUs with lots of threads for massive parallel work. An example configuration would be something like this, where CPU slot 2 is left open and can be filled later (the CPUs are cheapest on the used market - vastly cheaper, actually). Finally, unlike some other socket 2011 boards, this one does run on DDR4 spec RAM, so that's in line with your request. As it is, it can support up to a theoretical maximum of 1Tb RAM, but more realistically about 512Gb.

\n\n

Right now, this CPU sits near the absolute top of the performance charts, unless you start getting into E7 Xeons and POWER8/9, I think, and it certainly enjoys a fantastic price/performance ratio thanks to the flood of parts on the used market.

I'd like to create software on a desktop, laptop, mobile phone, or tablet that interfaces with the motors of the desk, allowing them to be controlled to raise, lower the desk automatically to two or more preset locations as well as being triggered automatically under certain circumstances. I imagine the motors would be connected to a controller that knows their position and can change their position to a known second position and the controller might have a bluetooth capability for integration with a computing device to control it. Alternatively, perhaps a USB connection could be used.

\n\n

What are some options for controllers that could provide this capability?

I think you'd have excellent luck with the Raspberry Pi A+ for ~$25. It has excellent documentation, some preexisting servo driver software, and integrated GPIO pins, which are the things you solder the controller wires from your motors to. It does NOT run a real-time environment, so stutter might occur, but for your use case that might not matter. At only $25, it makes sense to try this first and then add something like an Arduino Uno if stuttering IS a problem, since the Arduino will likely need to communicate with the Pi anyway. The big draw here is really the documentation; this is an incredibly well-documented platform with a lot of active users.

I'm on the hunt for a new pair of gaming headphones with a built-in microphone. I have a few hard requirements.

\n\n

I need the 'internal' size of the cups to be at least 70mm (my current pair is that size and fits perfectly) and fit a larger head size (I am not sure how to measure that).

\n\n

I'd like USB or a wireless dongle. Bluetooth would be OK, but I'd need to add Bluetooth to my system. A 3.5mm phone connector is kind of messy for my purposes.

\n\n

Sound quality should be decent - I'm not expecting audiophile quality sound, but I'd not want my ears to bleed.

It needs to be padded in all the right places - my past few headphones have had completely padded headbands, with fabric rather than pleather in contact with my head, and it's comfortable. Likewise, pleather, not raw sponge ear cups.

\n\n

I prefer closed cups over open cups. My parents have gotten into the habit of turning the lights off and on if they need my attention anyway.

RE: the Silicon Armor units:

\n\n

If you're talking about \"lifetime\" when operating in an ideal environment (good temperature, not a lot of hard impacts or water, mostly sitting still on a desk), none of the technical specs really give us any insight into how reliable the drives inside these enclosures actually are.

\n\n

Typically, a drive that does not suffer from any significant physical trauma or movement while in use will last for 5 to 7 years if used frequently, assuming there are no design flaws artificially limiting its lifespan. Even with military spec protective casing like these models offer, any hard impacts or significant movement while using it will probably reduce its lifespan by a large amount. Hard drives are too precise of an instrument to be thrown around; components will start to fall apart and lose their precision (and fail soon after) in short order.

\n\n

The only differences I could discern between the units were the levels of military spec (or lack thereof) certification, and the levels of IPX (or lack thereof) certification. The one that supports MilSpec and IPX7 is probably the best overall protected. That'd be the Armor A80.

\n\n

Also consider that the disks themselves could be low or high-quality, the firmware / disk controller could be low or high-quality; the connector ports could be low or high-quality; etc. which could affect lifespan of the device. If warranty service is not an option, you might want to shop around for more than one vendor. Also consider the opinions of both the original poster and the commenters here and think about whether an Enterprise-grade disk might be better (in some kind of portable enclosure).

\n\n

\n\n

Since you didn't state any criteria, for the WD disks I'll go with the My Passport Ultra because it's bigger and I (perhaps illogically) think that a larger disk is more likely to have some kind of padding / armor that'll make it more physically resistant to shock. ;-)

I'm looking for a possibility to make my desktop WiFi compatible. Currently I'm using a USB-stick that connects to the router, but it's not the best solution as it sometimes loses connection and isn't made for continuous service.

Is there a distinct hardware advantage between CPU's? My specific requirement will be for C++ coding and high end numerical analysis. I am building a new desktop system and considering the advantages of AMD vs Intel. Since graphics are of little concern, I'm having difficulty making that determination via google.

\n\n

Specifically, I'm trying to determine which of the following CPUs I should go with:

\n\n\n\n

I will be compiling software and using matlab and mathematica to do HPC.

\n", "Title": "CPU Architecture", "Tags": "|processor|desktop|", "Answer": "

This somewhat depends on the compiler, linker, and interpreter. If you are using a framework that is optimized for a certain CPU then you most likely want to go for that CPU architecture.

\n\n

At the assembly level, they both use the same instruction set and there isn't a distinct advantage. With C++, if you use something like Visual Studio, I found a site that performed benchmarks on Windows 8 - VS 2012 - Firefox compile. Here are the results: benchmarks. Although this shouldn't be a definitive stamp of success for Intel since it is somewhat dated, for other benchmarks you can find on that site, Intel does win in almost all cases with the i7 architecture. So although you don't really care about graphics, other applications you may run on your machine may have noticeable differences in performance in comparison.

\n\n

EDIT: I've noticed the question has been updated. Because of your specific requirements choices, I would definitely go with Intel. Now, between the two if you are going to utilize multi-core processing, then the Intel Xeon E5-2620 v4 will be optimal. Looking at this link: Core i7 vs Xeon you can see that in terms of multi-core processing Xeon performs better in benchmarks.

\n\n

One last thing, if price is a factor at all the Core i7-5820K can be considered over the Xeon. Just looking at a quick price check on Google between the two, the Core i7 is cheaper.

This fundamentally boils down to a motherboard question - what is the cheapest motherboard that can inexpensively support at least 512Gb RAM. Finding the absolute cheapest would be difficult, but I can suggest one that will not disappoint in making your total system cost a lot less than $13,000 (disgusting, innit?). Really this is going to come down to how great your ebay skills are, because the cost is going to utterly depend on the RAM modules you can acquire -and while you can reliably buy high-capacity DDR4 in stores for relatively cheap, you can sometimes find high-capacity DDR3 for cheap enough to justify that route. I will provide solutions for both paths.

First, the DDR4 build - it depends on the Asus Z10PE-D16. Please note that the rest of the build surrounding this motherboard is only to give you an idea of total system cost and likely configuration, and may not reflect a \"good\" design for your particular use case (Since I have no idea what you're doing, I'm just building it as I would for a sort of general use case in the vicinity of what you appear to be trying to accomplish).

I have seen a Youtube video of a PC gamer saying that he enjoyed gaming in 144 Hz, but he was amazed by 4k. However, I've also read a review by someone saying that you won't enjoy the 4k resolution until you hit 40\" as the pixel density is too high at lower screen sizes.

\n\n

Of course we're comparing apples and oranges here, but I would still like to ask someone informed whether an increased pixel density will satisfy the average gamer more than the increased refresh rate.

\n", "Title": "At 24\", does a 4k resolution at 60 Hz offer a better \"gaming experience\" compared to a 1080p resolution at 144 Hz?", "Tags": "|monitors|uhd|", "Answer": "

The benefit of framerate is not lineary increasing, as your eye does not notice the difference between 60 and 120 Hz as succintly as 30 vs 60 (if at all). Please consult:

\n\n\n\n

On the other hand, human eye has effective resolution of about 8 Mpx (please see for detais: What Is The Resolution Of The Eye?). The problem whether you see a difference is well discussed here: Can you see the difference with a 4K monitor? (brief: yes, you'll definietely see a difference, unless monitor is too small/you sit too far).

\n\n

It's a question worth thinking about, but I'd go for crisp picture or would consider something in between: ex. WQHD (1440p) resolution and 120 Hz. Also, keep in mind, that color quality and even back-light are also very important factors.

Is there a piece of hardware that can connect two monitors to a single video port? I want to fool an Xbox into thinking that it's connected to a single monitor, when in fact that display area is made up of two monitors on top of each-other. Something like this:

What you're looking for is called a Video Wall Controller. These are the boxes that you see behind the massive arrays of screens showing a single composited image in the big chain stores. They usually run around a $1000 or more. Without knowing the monitors involved I can't make a recommendation on which one to use. I know of no such products priced at private consumer levels, since usually that part of the market just uses a PC with two video outs to achieve the same thing (except, of course, that the video source has to come from the PC. You might try to rig up something with an HDMI-in capture card being passed out to two HDMI ports off a PC, but you wouldn't probably get true extended screen support - more like you'd have to span the image in a window drawn across both screens. Alas).

OK, I recommend the ASRock J3710-ITX Mini ITX Pentium J3710 Motherboard. This motherboard features an integrated quad core CPU that might provide the performance you're looking for - it's very difficult to say because you haven't given us a whole lot of information about the programs/dev environments you're using, but anyway it's significantly faster than your current CPU. Outfit this with at least 8gb RAM and a good SSD if you'll be caching any of that A/V data to disk.

Given that you're using OpenCV, it might be worth it to get an Athlon 5370 and board instead, as this would allow you to use the relatively powerful AMD GPU on that 5370 to accelerate your OpenCV work via OpenCL.

Although my personal preference is to remove the DVD drive, replace it with a caddy, and drop an SSD into that caddy (possibly with caching involved), a simpler, somewhat slower option that allows you to retain your DVD drive is to replace your HDD with an SHDD. I recommend the Seagate - 1TB Internal Serial ATA III/Serial ATA II Solid State Hybrid Drive for Laptops. This drive has 1Tb of slow storage, backed up with 8Gb of MLC flash, which it uses to automagically cache the rest of the drive according to how you use it.

It looks like normal older analog CCTV cameras pose no significant problem, they function basically the same regardless on manufacturer.

HIKVISION DS-7208/16HQHI-F2/N or similar, because it supports analog, AHD and HD-TVI cameras and a range of ONVIF IP cameras too. (Checked it with a new AVTECH IP camera and worked ok).

Dashua DVRs support different standard HD-CVI, so it is a matter of choice. HD-SDI cameras are generally a problem.

Dashua does not allow setting auto deleting old records per stream, HIKVISION does.

I\u00a0had an old PC (the build was originally a Siemens Celsius 460 workstation) whose case I wanted to strip apart and supply with newer components. For most components (those with standardised sizes, i.e. hard drive, optical drive, mainboard) this was easy but I ran into an unexpected problem when wanting to install the new power supply unit.

\n\n

The previously installed unit \u2014 an Astec AA21720 \u2014 was screwed into a metal in-between casing thing[1] and then onto the back of the case. The new unit \u2014 a Corsair VS350 \u2014 has its screwholes in different locations (what I presume is today\u2019s standard locations). It\u2019s not physically possible to fasten the new PSU with the screws and the in-between thing-a-ma-jig[1] provided and it\u2019s not really possible to screw it in without it. But, the new PSU, while being wider than the old one (15\u00a0cm versus 12.5\u00a0cm) is still slimmer than the width of the case (approx. 18\u00a0cm). This leads me to believe that I haven\u2019t lost yet. But let me show you some pictures first, so we know what we are talking about:

\n\n

\"Image
\nThe old PSU with the thing-a-ma-jig[1] to screw into the back of the chassis.

\n\n

\"Image
\nThe new PSU as is. But with the screw locations visible.

\n\n

\"Side-by-side
\nAnd these are both to compare them with each other.

\n\n

Are there any positioning-adapter thing-a-ma-jigsies[2] that I could buy and put between the new PSU and the back side of the case, so that all screws can fit into holes made for them? Sort of like the thing-a-ma-jig[1] the old PSU has, which basically allows to screw that one into chassis screw holes which are somewhere completely different. (If I could, I would buy the lowest-end cheap stuff because I don\u2019t give a damn about most of the cool things that a case can do, so assume the bottom end of the price scale for standard PC cases.)

\n\n

For convenience, I have labelled the two things I don\u2019t know what to call by superscripted [1] and [2]. Superscripted [1] always refers to the metal thing seen in the first picture, distinguishable from the PSU by its darker shade of grey. Superscripted [2] refers to some similar thing I do not own yet.

Find out what form factor the original PSU is, then buy a PSU Adapter Plate which will adapt whatever that form factor is to standard ATX.

As you've probably already worked out, Dell are one of the best for monitors. This is a pretty solid bet - I've not used one myself, but I know a couple of people who use either this monitor or a close relative and have been very satisfied with it.

After I invested on a laptop to start graphic designing I ended up finding out that AMD wasn't good for it and that my computer's power isn't enough(AMD doesn't support openGL render and I have just an i5 processor in my computer).
\nSo I was wondering if it was possible to install an external GPU on my pc. I am just a simple end use with not so much knowledge on hardware, and I was wondering if external nvidia graphic cards are available that would run via USB ports in my PC(windows 7).
\nIf not, what would be a work around for me that would provide me a similar performance of an nvidia graphic card and would support high and fast rendering(for 3D graphics,{specifically I'm using blender- cycles})?

\n", "Title": "external graphic card for pc(windows)", "Tags": "|graphics-cards|performance|rendering|", "Answer": "

Probably not, external graphic cards do not run via anything lower than USB 3.0. In addition that USB port has to be a thunderbolt port in order for an exteranl GPU to be supproted through it. This is simply because an older USB port doesn't have enough bandwidth to support the communication between a GPU and your PC, and also because it doesn't connect to the appropriate port on the motherboard. Thunderbolt ports however are based on PCI-E technology which is the same, as the one used by desktop graphics cards to communicate with the computer. Hence, if your laptop supports thunderbolt you would be able to purchase an external GPU chassis (like the one offered by RazerBlade), as well as a GPU that would convert PCI-E to thinderbolt, and plug into the proper port on your laptop. We would have to know the exact model number of your laptop to tell if it is equipped by a thunderbolt port.

You actually have an dedicated graphic card as well as an integrated. You have an AMD A series processor which has an iGPU, you should definitely chech if your cards arde compatible and if they support CrossFireX in order to get the most out of your system. As far as your RAM is ckncerned, yes you should definitely upgrade your memory to at least 8GB since you have a 64-bit processor in order for your pc to handle multitasking smoother... Your dedicated graphics card is pretty outdated as well, in fact i think your integrated may offer better oerformance (I haven't done any reserach on that it's just a feeling, you should check out if that's the case though, and if you can't run them in CrossFire, at least make sure you are using whichever one is better).

It's nearly new (1 month), and I would pay it 1300 \u20ac (I live in a European country). Full warranty, etc. Since Dell site prices it at 2050$, it sounded like a good deal and I got a verbal agreement, but...an acquaintance told me that the graphics card is \"crap\" (his words) and that there are better options at the same price. He pointed me to this laptop. I apologize for the non-English link, but I couldn't find exactly the same laptop on the English HP site. This one seems the closest one, but note that it has an HD twice as big (!). Anyway, it's not necessary to focus on these two.

It is a very long card, but it will fit in your case and one of the two 6/8 PSU cables you have will power it. Furthermore, while it will \"cover\" 2 of your SATA ports, 4 will be wide open, which is the requirement. I put scare quotes around \"cover\" because in my experience those ports are still definitely usable, you just have to put the cables in before the card. Sometimes you might need to use right-angle SATA cables, but those aren't hard to come by; at least one probably shipped with your motherboard.

Request: I want a box which converts from HDMI or VGA to Component 480p without introducing noticeable lag.

I do not know everything there is to know about video signals, but given that your TV probably only takes analog inputs, I'm going to suggest the White PC VGA to AV TV RCA S-Video Converter Switch Box Adapter here. Not only is this cheaper than HDMI alternatives, it has a better chance (in my imperfect opinion) of having less latency, because converting VGA to RCA signal is a totally analog process and so (I'm guessing) much simpler to do. I also like that you can power it from a USB port; a nice bonus feature that makes the whole setup a little less byzantine.

I boot operating systems like Windows 10, Xubuntu and Remix OS from USB storage.

\n\n

I bought myself a USB 3 flash drive and thought \"Hey, this can do 100 MB/s, it must be awesome for booting an OS from.\" (I do have a USB 3 port on my computer.) Well, it did perform that way in tests, but booting operating systems from it was an absolutely terrible experience. Xubuntu/Remix OS worked (though were slow and crashed frequently.) Windows crashed before it had even booted properly.

\n\n

\"Why is this?\" I thought to myself.

\n\n

Someone who apparently knows what they are talking about, told me:

\n\n
\n

For an Windows operating system boot drive, 4K random read speeds are the most important, followed by 4K random write speed, this is because there are a large number of small files in the Windows system. The 4K read/write speeds of the common flash drives are always slow, so these drives are not suitable for creating W2G drive.\n And the read/write speeds you said is sequential write read/write speed, not 4K random read/write speed, so it can't run Windows smoothly.

\n
\n\n

I also tried with an old mechanical drive I had lying around. It has only a fraction of the sequential read/write speed of the flash drive, but still, it works alright. Not as good as the internal HDD of my laptop, but still OK.

\n\n

But, what I don't understand is: The advice I quoted above indicates that \"4K random read/write speeds\" are the key to performance. However, I tested both the flash drive and the old mechanical drive, and the flash drive seems to score better, even in this regard. (The relevant entries are \"SanDisk\" and \"WD\".)

I am trying to find what video cards support a quad monitor extended desktop in Xubuntu. I've been searching forums and help pages and can not find a definitive option for a video card in Xfce that works on 4,5 or 6 monitors. At a minimum I want to run 4 monitors.

\n\n

Any recommendations on a card that works in this environment?

\n", "Title": "Video Card for Xubuntu", "Tags": "|graphics-cards|linux|", "Answer": "

Any Nvidia, Intel (CPU+motherboard), or AMD GPU with a displayport technology level above 1.2 ought to work, at least with the proprietary drivers. The problem is making sure that you have the right cable connections - in some cases, active adapters and/or MST hubs may be needed to make all 4+ monitors work reliably.

\n\n

If I had to recommend a GPU for you, I'd tell you to look at the Sapphire R7 250 Eyefinity Edition. You can connect two monitors to the DVI and HDMI ports, then add two or more displays using a splitter cable off the Display Port. Note that Sapphire claims it supports 3 displays in the tech specs, but the Eyefinity spec from AMD claims any GPU with that moniker supports 6. I believe this disparity is due to the fact Sapphire isn't including a DP splitter cable; such cards do work with up to six displays, as long as those displays don't exceed the total number of pixels each output is capable of pushing.

\n\n

Alternatives on the Nvidia side are similar, if somewhat more expensive on average. The company really tries to push its Quadro NVS cards if you look at their official documentation, but at least in Windows I have experience using GTX cards with DP outputs to connect up to eight monitors successfully. I don't recommend that setup only because getting those cards to work in Windows was never as successful as with the AMD cards, and the many weird issues I encountered make me hesitate to recommend it for Linux, where support tends to be even more wonky.

\n\n

The last thing I would like to mention is that unless space/energy is at a premium, it almost never makes sense to go with the NVS/Firepro solutions both companies offer up. These cards are expensive, inadequately cooled, and unecessary, because in reality you can just keep adding GPUs to computers and running additional displays off them without issues, so long as you have the bus connections (PCI-E normally, in this day and age). Thus in a computer with an Intel HD 4000 GPU on the CPU die connected to a DVI, HDMI, and DP out, adding two of the R7 250 Eyefinity edition GPUs above would allow that computer to push at least 3 displays on the Intel chip + 6 more on each GPU, for a total of 15 1080p displays. Any limits on that number discovered are more likely to be the fault of the OS than anything else, AFAIK.

I am willing to build my very first computer.

\n\n

This is the build I was thinking about:

\n\n\n\n

I am looking for a power supply that will work with this build. I am thinking of the Corsair CS550M 550W Black power supply.

\n\n

Is there a viable alternative that

\n\n\n", "Title": "Power supply advice - 550W range", "Tags": "|pc|power-supply|power|", "Answer": "

I strongly recommend against cheap PSU units or actually purchasing without researching a bit first.
\nA lot of the units on the market have really bad voltage regulation, especially on the 3.3V and 12V rails along with bad ripple. Furthermore, a cheaper PSU is more likely to trip on an input load that supposedly matches the output (for example 600W wall draw instead of 600W delivered on the rails).

\n\n

While it's generally true that with mild overclocking it will do 'fine', after all, the power supply must supply the motherboard, GPU and peripheral devices with clean power. I would not trust any components whose power load may spike on a cheap supply.

\n\n

From the recommendations above I support the EVGA and RoseWill supplies, and I'd also add most SuperFlower and SeaSonic supplies you can get your hands on. FSP (previously known as Fortron) also have very decent units that do not come off as expensive.

\n\n
\n\n

Regarding power draw, @Brett Bergan's suggestion for 160W for the RAM is outlandish. DDR4 RAM (without a ridiculous overvolt) will rarely consume over 3-4W per module.

\n\n

As for power supply, I would actually recommend a SeaSonic M12II 520 Bronze which is surprisingly cheap while still retaining full modularity and providing clean output.

\n\n

520W will be more than enough for your system until you decide to push things to the limits, and those PSUs can be trusted.
\nI've pulled over 1100W from the wall on my 850W unit (SS-850AM, Bronze efficiency) which is a bit over it's rated output and still didn't even trigger it's OCP.

I am choosing Wi-Fi adapter for my PC, the mo-bo is Asus z170 gaming pro and wonder which card to choose or whether go with nano usb stick like TP-Link TL-WN725N nano. I'll be sitting in the same room that roter is. I'm not sure whether it's better to go with PCI-E extension card or usb stick. What road (usb/pci-e) and what specific device would you reccomend?

\n\n

I use PC daily for work and gaming (so the ping counts), which equates to around 50 GB of transfer monthly.\nThe budget is 50$ but I really do not want to spend more than 10$ for fancy radiators and additional antenas if it is not going to provide any benefit.

\n", "Title": "Wi-Fi Adapter for PC", "Tags": "|usb|wifi|pcie|", "Answer": "

Personally, I would spend the time and do a proper CAT5e/6 installation; meaning running cable in/through the walls, terminating properly, hiding the network gear so it's out of sight. The benefit of being directly connected is the reliability of the connection is so much greater than that of WiFi.

\n\n

But...

\n\n

If you want to go wireless, I would forgo the USB route and go for a PCIe Wi-Fi adapter. It's not that USB is bad in any sense of measure, it's just you will get better reliability being directly attached to the PCIe bus rather than the USB bus.

\n\n

I have used the ASUS Dual-Band Wireless-AC1900 PCI-E Adapter (PCE-AC68) on a computer out in a warehouse where we couldn't easily run a network cable until we could get a crew with a scissor lift.

\n\n

\"enter\n\"enter \"enter

\n\n

What was nice about this particular model was that you had the option of plugging the antenna directly into the card or (what we did) use the optional \"base.\" This allowed us to put the antennas up high, away from the metal desk as to not interfere with the radio signal.

\n\n

The reason I mention this over USB adapters and obviously cheaper alternatives is because you mentioned \"a gaming mobo.\" Gaming requires bandwidth and this will deliver every time.

I'm looking to find a Bluetooth 2D Barcode scanner. I work at a local schoolboard and we receive shipments of Chromebooks for student use, so we have to tag and inventory each unit by inventory number and serial number.

The boxes have a QR code (which contains the serial number) and we place a standard UPC barcode on them. I've been using an Android phone to scan these, but it takes more time than a scanner usually does (focusing camera, etc).

I recently bought a GTX 1080 Founders Edition that I'm connecting to an ASUS ATX ROG STRIX X99 Gaming Board. I've heard that the new Intel i7 Processor would a good buy, but are there any other good gaming processors that would go well with my current equipment?

\n", "Title": "Recommended Processor", "Tags": "|graphics-cards|processor|", "Answer": "

If you're not going to be overclocking (though if you have that system, why wouldn't you be overclocking is likely a better question), then the Intel Xeon E5-1620 V4 is a better gaming processor than the Intel Core i7-5820K or the Intel Core i7-6800K. Those processors feature more cores and threads but lower clock speeds, and games don't yet really need more than eight threads. The lower price on the E5-1620 v4 is nice too.

\n\n

The only real downside here is that this is a locked processor, so you won't have any ability to overclock. If for some reason you're not going to be doing that, then by all means get the Xeon mentioned above.

Can anyone give me advice on a good mechanical keyboard? It's a present for my girlfriend, so i don't know much about them. Probably used for a 50/50 mix of gaming and typing. Would really like one with RGB back lighting.

\n\n

Budget ~$200 USD

\n\n

Appreciate any help.

\n", "Title": "Recommended mechanical keyboard for gaming/typing", "Tags": "|keyboards|", "Answer": "

I consider Brett's answer incomplete and rather subjective, so I'll toss in my two cents.

\n\n

First, there are great differences between the different switch types - and some of them can be rather annoying to the wrong person! It all boils down to preference.

\n\n

I will explain in short:
\n 1. Linear and Tactile
\n - Linear switches travel smoothly right down to the bottom. There is no feedback to your finger when the actuation happens so unless you are confident about the key travel/bottom-out (or look at your screen) you cannot be certain that the key has been actuated.
\n - When you push down a tactile switch, you can feel the actuation for when it happens the switch will give in a bit. In other words, the peak actuation force required for activation is a bit higher and upon activation it drops.
\nOut of these, I prefer linear for typing and tactile when gaming.
\n 2. Clicky and Silent (applies only to tactile switches)
\nThe names are pretty self-explanatory. I recommend watching a couple of videos in order to gather an idea about how clicky switches sound. Many people are very annoyed with the sound while others love it. Be very careful when you pick this for your girlfriend as it can turn out to be an annoyance either for you or for her...or both of you might actually enjoy it! ;)
\nI used to like clicky switches back in the day but I've grown to admire the soft bottom-out sound only.
\n 3. Actuation force
\nDifferent switches have different springs in them - some are lighter, while some are heavier. This is again a very important factor because some people tend to rest their fingers on the keyboard and are likely to accidentally actuate them.
\nI like heavier keys (60-70 grams peak actuation force) but most people tend to like 45g springs.
\n 4. Switch travel
\n- Classic Cherry switches have a 2mm travel before actuation, out of a total of 4mm travel.
\n- The new Cherry switches, Silver use the lighter (45g) springs and are a linear switch with a shorter travel time (1.2mm actuation, 3.4mm total travel distance).

\n\n
\n\n

Kailh switches are basically a Cherry MX rebrand after their trademark expired. There are also other brands which copy Cherry but let us not digress that far.

\n\n
\n\n

Now that you know all this, here is a listing of the most common Cherry MX switches:

\n\n

(switch colour - tactility, noise, stiffness, travel)

\n\n\n\n
\n\n

As for a keyboard recommendation, there are also different formats - depending on the use case, you might not need a numpad. I will recommend in each:

\n\n

Full size:
\nDucky Shine 5 RGB, because
\nSturdy and overall flawless build quality, which is very characteristic for the Ducky brand. Those keyboards are held in high regard even in the keyboard enthusiast circles;
\nYou can pick between Cherry MX Brown, Red, or Black switches;
\nPlug-and-Play;
\n14 pre-programmed lightning modes, along with 2 fully customizable (per-key brightness, colour, and pulsation);
\nABS Double-shot keycaps. ABS is a high quality plastic (usually last for well over 15 years before losing its characteristics) and only very rarely do you find stock PBT caps, with PBT being considered by many the ultimate plastic allow to last nearly forever on a keyboard;
\nAll the macro and settings profiles are stored on the built-in memory, meaning you can move it wherever and still keep your settings; \nUSB cable is detachable and replaceable. You can buy another, fancier one, or make your own if you so desire!
\nWhat the keyboard lacks for some people are dedicated multimedia/additional buttons, however all that either built-in (Fn+key combo) or is fully customizable anyway.

\n\n

Tenkeyless:
\nDucky One RGB TKL, because
\nIt sports a smaller size and is a more compact fit on your desk, leaving more space for your mouse and providing a more comfortable stance with less spread hands;
\nAgain a very solid build quality;
\nSlim bezels and compact frame which further enhance the space-saving benefit of TKL keyboards;
\nDetachable and replaceable cable allows for better portability;
\nPlug-and-play;
\nAgain ABS doubleshot keycaps with sandblasted finishing;
\nCherry MX Blue, Red or Brown switches;
\n10 lighting presets with three custom lighting zones;
\nEvenly lit legends on the keycaps.

So.. I'm building my very first gaming setup and so far it seems like it is really good and it will get the work done. I'm here seeking for suggestions from people who actually know about this. Will this run actual games in ultra? Maybe you can suggest me better fans to improve the default ones (quiter is better) Also, I'm using just one SSD, I see some people use two, why?

\n\n

Check the build on PCPartPicker or Amazon

\n", "Title": "Is this i7 computer worth?", "Tags": "|gaming|", "Answer": "

Well, some more information would be appreciated.

\n\n
\n\n

Use case:

\n\n

First, what kind of games do you play? Let us assume AAA titles as they tend to be the most demanding in terms of hardware.
\nSecond, what resolution and refresh rate do you play at? For 1080p, 60Hz you will be more than fine. Arguably, for that resolution your GTX 1080 is a bit overkill; a 1070 should suffice.

\n\n

For 1440p you should be able to max out all titles, possibly with a lighter form of anti-aliasing and a smaller sample count.

\n\n

Anything 4k you will not need heavy AA in the first place, so with tweaking demanding effects like some lightnings and AO you will be able to maintain 60 FPS.

\n\n
\n\n

Suggested changes:

\n\n

My recommendation for your build would be to change the CLC to a good air cooler. They are bulkier indeed, but offer equal, if not better, performance at the same price point often with less noise produced. Something like this should do the job, and do it good.
\nOn that note, if you intend to go past a soft CPU overclock (anything over 1.28-1.3VCore) for 24/7 usage, I would recommend a motherboard with a beefier power phase design.

\n\n
\n\n

Further information:

\n\n

The number of SSDs doesn't really matter, unless you need the tremendous speed from a RAID 0 array.
\nOn that subject, you could use the m4 socket for the same SSD and squeeze out some extra performance while having less clutter.

I am looking at purchasing a new computer within the next few months, for use in work applications. I am an IT project manager (read groupie for programmers/DBAs/engineers), and have multiple clients with different needs. I need to be able to compile with Visual Studio 2015, maintain like 40 browser tabs across multiple instances simultaneously, run multiple instances of Excel, Access, and SQL Server each at once (Office 365/2016), Outlook, Project, Remote Desktop Connection, sandbox MS IIS, and similar productivity stuff. I will need to stick with Windows 10.

\n\n

Currently, I just use the HDMI port to output to an LCD TV. I would probably continue that practice, but I assume VGA and DVI cords would work just as well on this and similar screens. I only use one screen right now, but I really should have multiple video output ports for future use. I also use a cheap USB wireless mouse/keyboard. I have a preference for 1) maintaining wireless, and 2) not paying for another mouse/keyboard. I seldom (3-4x/month) use USB, and doubt I would use more than 1 (besides my mouse/keyboard) at a time. I would like to have a CD-ROM (writable) drive, partially because I miss my cup holder, but I also get CDs about 5x/year.

\n\n

I would like to have the option to be able to run additional OSs in order to replicate user environments at some point, and a virtual environment would be useful for other reasons. Neither would be common occurrences.

\n\n

I plan to pay my ISP (once I am set up) to allow me to log into this machine remotely with one of my laptops, so I can still use it for processing and file serving while on site at a client. I am not a networking guy, and SE will undoubtedly be helping me to get that set up. I care little for the actual display quality during such a setup, but I will need to be able to open multiple very large (150x1,000,000) size spreadsheets, and do sort/filter on that data, displaying the result through remote desktop to my laptop. Probably nothing more intensive during the remote connection.

\n\n

Building the computer myself would be cool, but that is about where the benefit for that (probably) ends. I remember installing a second 5.25 floppy drive on my first computer, and later an entire 20MB HD in the same computer (there was no one cooler than me in the whole world, at that point), but that is about where my building skills peaked. I soldered my brother's Playstation, installed multiple 4MB RAM sticks, and even took apart the power supply once. Now a days, I should be considered a novice at best in hardware matters. But, my wife's brother has a friend who knows a guy who says he could probably build a computer, so there you go.

\n\n

This will definitely 100% be a business expense. That said, it might be nice to know I could do some leisure stuff, in case I ever get my work caught up. The most advanced game I have ever played is Civilization 4, and I can't imagine getting much more advanced than Civ6 within the next 4 years, and would probably be content sticking with Civ4, low graphics settings (I like what I like).

\n\n

I don't really need to worry about any more expansion capability beyond what I have already mentioned. If my business is doing so well that I need to upgrade in less than 5 years, I can afford to buy another machine.

\n\n

So, knowing that I need to purchase a Windows10 Pro license, are their any scenarios where buying the pieces and putting it together myself would be cheaper? (I doubt it)

\n\n

Do different manufacturers have different track records, at the amount of computing power I will be doing (not much)?

If you do have a M.2 NVMe capable slot, then there's no question: go for that. SATA is really not suitable for modern SSDs anymore(the numbers you see with the 850 Pro are SATA maxed out).

I have an HP proliant micro server sitting in my home office and I want to stream photos and videos off this device and display it on my TV in another room. The TV also sits next to an ethernet hub and my preference is to connect the TV to network via this hub.

I got an offer to buy a used Core i7-4770 with Asus Motherboard and 16 Gigs of DDR3 RAM for 200 Euros. This offer comes to pass very good because I am thinking about upgrading my computer.

\n\n

Currently, I use an AMD FX-6300 on an MSI Board which recently started having issues on boot. GPU is the Sapphire R9 270X, but I will upgrade to an GTX 1070 soon.

\n\n

My question now is, should I take that deal for 200 Euros or should I save some more money to take a new i7-6700 with DDR4 instead. How is the Performance to Value comparison?
\nI compared the two CPUs using CPUBenchmark.net and the Benchmark Points are different by just 200, which does not seem much compared to the difference from my FX-6300 to the i7's (which is about 3k Points difference).

\n\n

In case you need some information about my main usage of the PC, I play a lot of games like Rainbow Six Siege, The Division, Overwatch, Paragon (guess that's the cpu-heaviest game of those) and I also do a lot of rendering to MP4 (live and non-live).

\n", "Title": "i7 4770 Cheap Deal vs i7 6700", "Tags": "|gaming|processor|", "Answer": "

You should seriously consider the newer chip for rendering.\nI shall weigh up the + / - as if we refer to upgrading to the newer CPU.

\n\n

- It has been shown on TOM's hardware many times that there is little difference for gaming, due to the CPU clock-speed being a big factor in games still. Consider this a small minus as CPU has VERY little effect on game performance (it's all about GPU, baby!)

\n\n

- You will need to buy new RAM as you stated, and it's not really much better in performance for games... Video it is, but only a little bit.

\n\n

+ Power usage / thermal control is a LOT better on the 6000's, so it will distract your gaming a lot less with quieter fans.

\n\n

+ Video encoding MUCH faster on the new i7's if the software is optimised for it (it will be).

\n\n

+ (this is the one that got me) Upgrading Mobo means you get all the sweet new features such as USB3.1 and type-C connectors. Future-you will thank you for this investment.

\n\n

Also, EUR200 is too much for that old CPU. I mean, performance-per-dollar it's OK, but if you really look hard for second-hand machines you will find one (probably with case and PSU) for half that price.

I am planning to buy a gaming laptop and I have narrowed them down to these two laptops

\n\n

MSI GE62VR Apache Pro-001 - Price Around $1200 - $1300

\n\n

MSI GP62VR Leopard Pro-218 - Price Around $1100

\n\n

I am sure that I need a gtx 1060, given how poor of choice it would be to take a 900 series gpu based laptop now. Also I need a 1080p laptop (since I need only a 15.6 inch screen and I feel that a higher resolution at this size is not that noticeable) itself, so going for a higher end gpu like a 1070 is probably overkill for a 1080p laptop.

\n\n

The only major difference between them is the VRAM. For GE62VR there is a 6 GB VRAM for 1060 gpu, but for GP62VR there is only 3 GB VRAM and I read that the extra 3 GB is not that needed, at least for the next 3-4 years to come (correct me if I am wrong). Also one more thing that bugs me is the fact that there are no reviews about GP62VR, so I am not sure if it's a good laptop. However the GE62VR has many good reviews online, but the GP62VR is a bit cheaper.

\n\n

So given the circumstances, and my current budget of about $1100 - $1300, which of these two laptops would you suggest?

\n\n

P.S. On a side note, for my budget, would you suggest a different 1080p, GTX 1060 laptop altogether aside from these two?

\n\n

Edit: \nI plan on using the laptop for gaming and maybe learning 3d modeling, game design etc in future, so I may run cinema 4d, blender, adobe products in future but only as a hobbyist or a beginner.

Changing the CPU is not as easy as adding RAM or swapping a HDD. It is a FULL dissasembly. Have a look at this video here. Still want to do it, then narrow your list of possible options.

I need a home server for running couple of services, since my current hardware is aging. For example:

\n\n\n\n

USB 3.0 is a requirement, since I want high I/O-Rates beyond 25MB/s, also access times should be fast (e.g. Hosting the library of a photo manager on the network share with lots of small file reads). The CPU/RAM should be juicy enough to carry out those requirements on the various file protocols, and to run the ownCloud PHP stuff smoothly.

\n\n

I want to focus on low power consumption because of the 24/7 runtime. The number of hard drive bays doesn't really matter, I'm using USB-Drives so far and don't necessarily need to change this. Operating system will be some Linux, I don't want any custom/proprietary flavour e.g. Synology DSM, just plain Linux with full control. Display output won't be needed at all. No redundancy is needed as well, so one PSU and one gigabit Ethernet port should be enough.

\n\n

What kind of hardware should I choose to get the most performance with least power consumption and lowest cost? I thought on ~400\u20ac (~430$) max, don't know if that's possible. Of course it'd be nice if the requirements were possible at even less than 400\u20ac.

\n\n

Your requirements sound similar to my home server, except that I went with an internal RAID-6 array -- so that's $400 in hot-swap bays, cases, and controller cards you won't need to spend.

\n\n

At the cheaper end of the price range, buying pre-made usually costs less than building your own. The mostly-preassembled option I'd recommend would be an Intel 2550L2D-MxPC for about $130. It's got an Atom D2550 CPU (four years newer and considerably more powerful than my Atom 230), dual gigabit ethernet, two USB 3.0 and four USB 2.0 ports. You'll need to add RAM ($45 for 8 GB) and a boot drive ($40 for either a 500GB hard drive or a 120GB SSD). Like almost all of Intel's products, it's Linux-compatible.

From Seagate's data sheet, I've noticed 3 things:

\n\n
    \n
  1. The only thing different across different models (with different serial numbers) is the capacity.

  2. \n
  3. STEB5000200 is marketed for EMEA region (Europe, middle east and africa), while STEB5000100 is for America (NA I would suppose).

If you where to combine 4x titans how many teraflops do you get? just a pic

\n", "Title": "How many gflops does 4 way sli titan x pascal have?", "Tags": "|graphics-cards|", "Answer": "

The theoretical single-precision rating of a single Titan X Pascal is 11 TFLOPS per the media (ArsTechnica).

\n\n

If you multiply 11 by 4, and assuming you have enough PCIe lanes to support all of these GPUs under full load, and assuming you have enough CPU and memory bandwidth to \"feed\" a real workload to each of these cards maxed out, that would be 44 TFLOPS single-precision.

\n\n

You will never be able to use this kind of raw horsepower for gaming, even with an ideal workload on DirectX 12's EMA. The only way you could hope to utilize it all would be with a very high-end CPU (or perhaps multiple Xeon E5 CPUs), high clock rate DDR4 for system memory, and using OpenCL or CUDA on embarrassingly parallel single-precision workloads.

\n\n

Thank you for your answers.

\n", "Title": "Can 2 different model rams can run well together?", "Tags": "|memory|", "Answer": "

Generally, yes and without issue. However it will depend on the memory controller (Modern systems have moved this onto the CPU itself).

\n\n

In almost all cases on modern systems you will see the RAM down-clock itself to match the lowest denominator of the chips, this might lower the FSB and the timings.

\n\n

If one of the chips runs at an odd voltage however, I would not advise mixing them as the system likely won't finish POST.

\n\n

Finally, if you have two banks for memory (1+2 & 3+4) generally the mismatched pair should sit on different banks. Refer to your motherboards manual for confirmation.

\n\n

On the performance upgrade of 20%, we can't say without knowing what your utilization looks like and if RAM is the bottle neck. 4GB is a good minimum for just about any computer, doubling to 8GB+ will almost certainly provide a noticeably gain for most applications.

I am not aware of any non-x86 consumer-level CPUs, ie. ones where you can simply purchase and slot together all the parts for a computer.

\n\n

Various ARM CPUs can be purchased individually, and OpenCores has some CPU designs that can be loaded up on an FPGA, but these aren't end-user-friendly: they require sufficient electrical-engineering skills to design a mainboard for connecting the CPU to things like memory or a video controller, or at least the assembly skills to build someone else's design.

I have an older Logitech 5.1 speaker system for my computer that uses 3x3.5mm plugs for input. All of my newer computers only have a single 3.5mm output that handles 5.1 + voice (apparently I was mistaken, this is not possible).

The other answer's suggestion is a bit expensive for my taste (with several hundred dollar).

\n

So I can recommend the soundcard I'm using myself to power my 5.1 speaker system. However you don't really need all the features so instead I'm gonna recommend the functionally largely equivalent, but cheaper version:

\n

The ASUS Xonar U5

\n

On Amazon.com and on the official website.

\n

For the relevant I/O it features 3x 3.5mm jack output for your speakers as well as S/PDIF. The audio processor seems to be just slightly worse than that of my card but should still do a good job. Not that I don't know whether Dolby Live (a driver technology to dolby digital encode the system audio on the fly so you can squeeze the data into the bandwith limit) is a thing for the U5 so you may not be able to use more than two speakers over SPDIF.

\n

OS compatibility is a given and it will work with all Windows and OS X / macOS versions (at least down to Win7).

\n

If you're feeling fancy you could also go with the Xonar U7 however then you'd have to look out for the fact that left and right have RCA instead of 3.5mm jack output (but the bundled software seems to be better with the U7).

Sockets are the answer. Generally, modern intel CPUs use sockets in the LGA 11xx format. I don't know what your CPU uses for it's socket, but before you ask: no, you cannot get socket adapters for cpus. If the sockets aren't compatible, you need a new motherboard, and maybe more.

I have been moving my DVD collection to a 2 TB external hard drive, and I was wondering what my options are for viewing the media.

Like BigElittles, I'm a Plex fan, and my current preferred method for viewing my own videos and photos is Plex-through-Amazon-Firestick. If I had a smart TV (w/web browser), I may have accessed Plex via the web interface - I have Plex running as a service on my home server.

\n\n

I also use Kodi; it's possibly more expandable than Plex, but certainly I think Plex is the more polished of the two.

\n\n

Prior to this, I used a Western Digital WDTV box and an AC Ryan Playon HD Mini - both essentially the same thing: a little box that connects to your network, and/or local storage and plugs directly into your TV. Out of the two, I preferred the WDTV box. Most of these devices have a fully functional remote, rather than the simplified remotes that come with the Firestick/Chromecast. Roku 3 is the current offering from the supposed 'market leader'; I don't have any experience of these, but they are well liked and respected.

\n\n

Given the rise of Plex/Kodi & Firesticks/Chromecast, these Media Players are falling out of favour, so should be fairly cheap to pick up. In fact, I still have both of mine, because the resale value of them is so little.

\n\n

Furthermore, unlike Firesticks\\Chromecasts and the like, they don't require a computer/server/NAS to provide access to your external hard drive. You connect your TV to the media player and your external disk to the media player and you are up and running.

The size should be between 24\" and 27\". I don't have enough space on my desk for a bigger or ultra wide screen.

I need to fit a fully-functioning mobo with an LGA1151 cpu socket and a PCI-E x16 slot for my gpu and at least 2 RAM slots in a 11 x 5.5 x 7 case. It also has to have a maximum RAM capacity of at least 32GB. No need for fancy stuff like LED controllers or anything though. Just the bare functional basics, because it will be in a very closed off case, so it doesn't need to look nice at all. Does anyone know of a 1: Very small but full-featured motherboard, or 2: a company that would be willing to manufacture 1-2 motherboards of a very small size for a couple hundred dollars. Any other options would also help, but those are the main 2 things I'd be looking for. My budget per board is around $250, give or take a bit.

To translate your dimensions into normal terms, you're looking for a Mini-ITX (or Mini-DTX) board.

\n\n

I'd recommend the Asus H110I-PLUS/CSM, $86 from Newegg:

\n\n\n\n

The chipset and voltage regulators are passively cooled with small heatsinks, which may or may not be a problem for a \"very closed off case\".

\n\n

I don't have any experience with this particular product, but I've had good luck with Asus mainboards in the past.

\n\n

Here is a Wikipedia link to form factor sizes for reference. This can provide you all the options for size options that are offered based on size standards. Keep in mind that anything smaller than Mini-ITX is unlikely to have a PCIe slot, and is likely to have just a single SO-DIMM slot for memory.

You can upgrade your laptop from 6GB to 16GB of RAM, but I would only do this if I needed the extra RAM. Having extra RAM isn't going to make a difference in performance you aren't said extra RAM.

\n\n
\n

I'm asking if it is a wise choice to upgrade a my laptop to 16 GB of RAM knowing that I have a processor with only 2 physical cores.

\n
\n\n

In response to that, core count doesn't necessarily mean you can't use more RAM. You should be able to utilize as much RAM as the manufacturer says is supported.The i5 3230M supports up to 32GB of RAM, but I believe this is limited to 16GB in your laptop (due to chipset limitations?). Furthermore, your laptop's i5 3230M is dual core and hyperthreaded. Basically, it's like having four cores.

If you feel like you need more RAM for your laptop take a look at something like this:

I am preparing to build a new tower, the first in a long time, and am aiming for it to be a \"baseline\" for upgrades for a long time.

\n\n

It will be used with a dual boot Windows 7 / Debian, Windows for gaming and Debian for everyday tasks (multimedia) and programming (nothing CPU intensive yet).

\n\n

The goal is to have it built for a relatively low price, performance be damned now if must be since I don't have a lot of PC games yet, but I value the future proofing above all.

\n\n

I am hesitating between three processor, the difference in price is not that huge, but the sockets are different, and I'd like to know that when time's come, I ll not have to buy a new motherboard with the next processor too because I have choosen the wrong socket.
\nI'd also would like to have the more bang for my buck, since I am on a tigh budget for my ambitions.

\n\n\n\n

EDIT:

\n\n

To clarify a few point, my main worry is to, in some year when the processor will start to get old, have to change the motherboard with it because of a change of socket, followed by changing something else because X is not compatible with the new motherboard, and things cascading in buying almost a new PC.
\nI am also not in a hurry, so if the release date of a new socket type that will be supported longer is scheduled for soon (<1year), I am also comfortable waiting for it.

\n", "Title": "Processor socket, 2011-v3, 1151 or 1150?", "Tags": "|processor|", "Answer": "

I suggest you to read these articles: for 2011-v3 successor\nhttp://wccftech.com/intel-x299-chipset-skylake-x-kaby-lake-x/ and for 1151 successor\nhttp://wccftech.com/intel-cannonlake-cpu-300-motherboards-2017/

\n\n

They clearly explain that the x99 / 2011-v3 socket and x200 / 1151 won't last more than few months, since it's almost certain that intel won't support them with newer cpus (skylake-x and cannonlake/coffelake).

\n\n

Since you repeated a lot the word FUTURE I have to say that you have chosen sockets/chipset that won't be upgraded anymore by Intel with newer CPU.

\n\n

So one option is to buy something NOW, and I suggest to choose the 2011-v3 platform with the right motherboard because you are sure that can buy now a Core i7-5820K (3.3GHz, L3:15M, 6C, HT, 140W, rev.R2) and in the future update it to a, for example, Intel Xeon E5-2687W-v4 (3.0G,160W,L3:30M,12C,HT) with less money than today (also selling your first CPU).

\n\n

The other option is to wait for the next first next platform between X299 or cannonlake/coffelake chipset 300 and you will be sure that for other 2 generations of processors you will be able to upgrade them. I would suggest cannonlake cpu that will be also 6/8 cores (plus HT) instead of the top cpu of 1151 that is only 4 cores (plus HT). Sadly my last phrase has no direct support from leaked slides (see: http://wccftech.com/intel-roadmap-kaby-lake-coffee-lake-cannonlake-leak/ and: http://www.fool.com/investing/2016/09/14/exclusive-the-secret-of-intel-corporations-coffee.aspx ) so it could be taken as a speculation.

\n\n

Take into account also that this year AMD will show ZEN CPU and in function of the real value/performance of the platform I think that INTEL will be forced, or not, to push to an higher rate of cores on mainstream cpu sector

My employer intends to purchase a laptop for me in the USA, then send it to me in South Africa. I've read that the GTX 10 series cards have desktop level performance even on laptops.

\n\n

I've asked around, and Dell is really the only supplier that will support the laptop internationally.. i.e. I won't need to ship it all the way back to the USA if I need repairs.

\n\n

I've looked at local suppliers that have MSI and ASUS laptops with GTX1080's too.. but they are very bulky and look like too much like gaming rigs (which they are). This new alienware range actually looks a little more conservative and they're slimmer than the other gaming rigs. Ultimately the looks don't matter though. It's just a small consideration.

\n\n

Note: This isn't for gaming - it's for design work.. with a preference for fast render times in a laptop (I will be travelling a lot).

\n\n

I've been looking at the Alienware 17 R4 laptop:

\n\n

It's a 17inch UHD (3840 x 2160) IPS screen - so the color accuracy should be decent. It contains a GTX 1070 with 8GB GDDR5 Also it has: 7th Generation Intel\u00ae Core\u2122 i7-7820HK (Quad-Core, 8MB Cache, Overclocking up to 4.4GHz )

\n\n

There are 2 more expensive Alienware 17 configurations that have GTX 1080s, but they have TN panels.. so I'm leaning toward this IPS one. I intend to max out the RAM and take 3 years of Premium support and accident cover.. so the total cost comes to about $3100

\n\n

So with that budget in mind.. there's also the whole precision line from Dell.

\n\n

The New Precision 5520

\n\n

It's 15inch UltraSharp UHD IGZO (3840x2160) Touch Wide View LED-backlit with PremiumPanel Guarantee - so I guess this might be an even better screen.

\n\n

If I select specs like the highest end processor: Intel Core Xeon E3-1505M v6 (Quad Core Xeon 3.00GHz, 4.00GHz Turbo, 8MB 45W, w/Intel HD Graphics 630 32GB Ram, add the same HDD's as the alienware etc..

\n\n

The price comes to 3,014.90 (so basically the same as Alienware)

\n\n

The Graphics card difference would be that this has a Nvidia Quadro M1200 w/4GB GDDR5

\n\n

So which of these 2 laptops do you think would render and work better in blender?

\n\n

I don't do big complex scenes.. it's mostly simple product packaging and bottles.. some glass.. sometimes a simple area to display items like a table with light streaming in from a side window.. wooden surface sometimes. But nothing crazy. I do need to do A LOT of renders though.. so we need something snappy.

\n\n

Thank you!!

Just to get a level of comparison:

\n\n

The professional (workstation) videocards in the Nvidia family have usually the 1000 / 2000 / 3000 / 4000 / 5000 numbers, prefixed by the generation letter. They correspond to X40 / X50 / X60 / X70 / X80 of the consummer editions.\nSo, for example, M5000M is roughly equivalent of the 980M.

\n\n

Following the same logic, the newer Nvidia GTX 1070 will have as equivalent Nvidia Quadro P4000M.

\n\n

But from the 9xx line to the 10xx line the jump was fantastic. For example 1060 is a something between the previous 970 and 980, while taking less power.

\n\n

So what you are comparing here (M1200) to GTX 1070M is like comparing 1040 to 1070. You say what? There's no GTX 1040? Yes, you're right, that's how low that video card is.

\n\n

You simply cannot compare them. So, if what you need is video processing power, there's no question.

\n", "Title": "Graphics card to support UHD (4k) HDR screen over HDMI", "Tags": "|graphics-cards|4k|", "Answer": "

Actually, you don't necessarily need to upgrade the CPU. A PCIe 3.0 card will work in a PCIe 2.0 slot. However, you may experience slightly decreased performance. You mentioned that frame rates were irrelevant, so PCIe 2.0 shouldn't be an issue.

\n\n
\n\n

If you do want to upgrade to a CPU that explicitly supports PCIe 3.0, one of the most inexpensive options is going to be something like a i5-3340. Which will be a modest upgrade from your i3 3225.

As for a GPU I believe you will need something that uses the Maxwell or Pascal architecture for HDR (assuming you want to go with nVidia).

Though it will likely not be able to handle cutting edge gaming at max settings, without major upgrades.

The two bottlenecks of file copying are transfering from the external hard drive, and writing to the internal drive. Everything else in a modern computer is much, much faster than the drives.

My recommendation is that you go to a local store and buy the cheapest computer you can find that has one or more USB 3 ports (USB 2 is roughly the same speed as a hard drive; going with USB 3 will eliminate the connection as a potential bottleneck).

An old software question of mine looks like it would benefit from some hardware.

\n\n

Basically, I have a web page and want it to communicate via HTTP to a small controller, which will read a string from the serial port and return it to the browser.

\n\n

Don\u2019t worry about the software, I can handle that. I am wondering which hardware to use, and would like to keep the price down.

The requirements are simple enough. The device needs to be able to read from serial port, and it needs to be able to receive HTTP requests - I don\u2019t care how. I don\u2019t really need an operating system, certainly not a full blown one, but I do need to be able to run a web server, to handle the HTTP request.

\n\n

I was thinking Raspberry PI, but am one to other solutions if they are cheaper and if they are as simple to code. I can buy in quantities of a dozen up to maybe 100, if it offers a decent discount.

[Update] I also need a dozen or two GPIO pins

\n\n

Possibilities:

Long term availability of the device might play a role. E.g maybe not use Pi2, in case it gets phased out. Widely available support , via forums, would be good, although the project is so simple that I don\u2019t envisage needing any help.

It depends on the chips in the adapters (see hdparm docs). Mine don't\n support it, and the only one of them that I can warn you about is the\n Seagate desktop expansion drive, the others have no branding.

In man hdparm it says

\n\n
\n

hdparm provides a command line interface to various kernel interfaces supported by the Linux SATA/PATA/SAS \"libata\" subsystem and the older IDE driver subsystem. Many newer (2008 and later) USB drive enclosures now also support \"SAT\" (SCSI-ATA Command Translation) and therefore may also work with hdparm.

\n

However, I bought one which is support to support SAT, and reflected on the word 'may'.

I checked out https://www.smartmontools.org/wiki/Supported_USB-Devices. This is a list of devices which support SCSI-ATA Command Translation. I got a Gembird AUSI01.

It... didn't work. Just said 'erase prepare: invalid argument.'

I checked the adapter via USBdeview. It's genunine: correct chipset and device ID. It was able to work with smartmontools commands that I tried. It just wouldn't do Secure Erase, despite reporting that the drive could do Secure Erase.

I'm posting the results of my own investigation here since none of the previous answers quite did the trick (either because of weight or price).

The laptop that comes closest to the solution for me is this Asus Zenbook, which weights only 1.45 kg and has a 2.5 GHz Intel Core i7-6500U Dual-Core with 8GB RAM.

Granted it's not the most powerful laptop listed here, but it has still good specs and the and low voltage processor that should increases my battery life.

I am a long running user of the cherry mx red key switch, and I love it! I have used both blue and brown and didn't like either of them. I use my keyboard for intense gaming sessions but also for typing, as I am always typing large documents for school. I have a high typing speed of almost 100 WPM so the cherry mx reds don't feel like they are restricting me from typing at my ability, but rather aiding it.

\n\n

I like the look of the razer blackwidow V2 keyboard but they use their own key switches. I was wondering what razer key switch would most closely compare to the cherry mx red, and any major similarity's and differences, or pros and cons of the razer key switch over the cherry mx red for my purpose (Gaming/Typing 50/50)

I'm actually using the Razer Blackwidow 2016 Stealth Edition and I really love it , it's really smooth and reactive. Though my girlfriend likes it less than I do because she can't sleep when I play or type things because like a lot of mechanical keyboards it makes some noise, which is a negative.

This is what I found about the Cherry MX Red:\n\"cherry

SO, I really love my Moto X 2, and it still work very well, but it's starting to get a little old... the battery doesn't last as much as it did, and the 2GB of RAM is starting to get a little cramped. Also, as usual for Android phones, the software stopped being updated.

\n\n

\n\n\n\n

Is there any current phone that have those features, but with larger RAM, preferably longer battery life, and size equal or smaller? If it can cost less than $400, even better.

Almost all always-on voice recognition phones are flagship phones. Unfortunately the smaller phones tend to be budget phones, which means they lack the always on voice feature.

\n\n

The prices on flagship phones are usually far past the $400 mark but here's a list of recent Android phones that I should have always on voice feature:

\n\n

LG V20 (around $700)

\n\n\n\n

Google Pixel (around $750)

\n\n\n\n

Moto Z Play/Moto Z Play Droid (around $400/450)

\n", "Title": "What does \"fully wired\" mean when buying a PSU?", "Tags": "|desktop|power-supply|", "Answer": "

A fully-wired PSU is simply a non-modular PSU, and comes with all power cables hard-wired. A semi-modular PSU has the essential cables hard wired and the other cables socketed. A (fully) modular PSU has all power cables socketed. To quote Overclockers:

\n\n
\n

Whereas non-modular power supplies come with all possible cables already attached, a modular PSU comes with connectors, giving you the freedom to use only the cables that you really need. There are two types of modular PSU, and the one you decide to go for will largely depend on your requirements and budget. A semi modular PSU comes with only the essential cables wired on\u2014usually the ATX 12V and EPS 12V, and in some cases the PCI-E cables\u2014whilst a fully modular PSU comes with no cables whatsoever. A semi modular power supply offers a more affordable solution, whilst a fully modular power supply allows for ultimate cable flexibility at a somewhat higher price point.

I have a big crowded hall (around 200-300 persons) that I need to cover with Wi-Fi coverage, these people need to access a web server inside the network (it's an intranet). So what is the best hardware implementation? I have a budget of 280$-300$ only.

I would try 4 dual band routers (i.e. they can use a channel in the 2.4Ghz range and one in the 5Ghz range at the same time), and set them up on different channels to minimize interference, checking for this. Go for the best routers you can get from your budget. Spread them over the room and connect them to an Ethernet switch. Try out different positions to get the most from your hardware.

\n\n

An example of channels you could choose are channels 1, 6, 11 and 14 for 2.4Ghz as per this section and channels 36, 40, 44 and 48 for 5Ghz (I just chose the lowest non-overlapping channels allowable for the USA as per this). It should not matter how you pair those channels onto the different routers, so for example routers with

\n\n\n\n

You all set them up with the same SSID and password, but otherwise nothing special, just as you would for single APs. The clients will choose the best available AP (also switch between them transparently if necessary).

\n\n

The router/AP you mention in your comment is a single-band 2.4Ghz one. I suggested dual band ones. One hint as to whether what you are looking at is dual or single band is that dual band ones (usually) have two antennas while single band ones (usually) only have one. But check the specifications! Dual band routers should perform as good as one router in one band, and a second in the other, so essentially you could two in one.

\n\n

I think this could work, but no guarantees. The university WWAN where I study tends to get flaky in full large lecture halls (i.e. 300-400 people) and they probably spent quite some time and money optimizing it.

Hello community,

\n\n

Back in 2013 and build my own PC finaly. But nowdays i think its kind old for stuff i am doing at PCs.

\n\n

What I do on my pc now?

\n\n

I like playing games . Recently i discover That CS: GO consume 80% of my CPU (am playing FullHD) That a lot i think.\nI was trying Ghost Recon: wildlands open beta, we frame rate about 20-36 FPS and low settings in fullHD. Other games I play are sometime strategy but also want to play games modern.\nWith friend we play games and sometimes am a host.

\n\n

I am also YouTuber / Streamer\nSo i make few videos Ghost Recon form, but also record it with nvidia share (with GPU Takes the hard part). For recording using OBS am with nvidia nvec, and same setting for streaming in 720p30 in some games in 60 FPS.\nCurrently we streams are ok, but sometimes get laggy Because the CPU and GPU.

\n\n

Photoshop, video editing, rendering\nFor pictures and graphic am using photoshop Currently Seems like i have enough power.\nFor editng video rendering and i think its not. Take a long time to make a 20 min video like 40-50 min to render in fullHD.\nJust for fun i am rendering Also fractals, but its not import.

\n\n

Sat Those are the most stuff i am doing on my PC. Sometimes am and hosting games and streaming and so on.

\n\n

My curret build\nCPU: Intel Core i5-3550p \nGPU: Nvidia GTX 660Ti \nRAM: 16 gigabytes 1600MHz (two slots)\nMB: Asrock Z77 pro3 \nDrive: 1 TB Western Digital\nPSU: Corsair 600 Watts

\n\n

My budget\nI save 400 dolars for upgare.

\n\n

My opinion\nIn my opinion i need to buy new motherboard and CPU. I am not a guy looking for graphics.\nI was Considering Intel Core i5-7600 or i7-7700 \nand motherborad

\n\n

But i am not sure if it buy new CPU or GPU to boost performence for gameing and recording.\nAnd the same time there is a Ryzens with AMD, onestly i am not a fan of AMD i have a bad experince with Them in a trap.

\n\n

I want to buy new HW for next 4-5 years. \nAlso i not sure if i need CPU with K, beacuse i never do it

\n\n

Future GPU\nIn near future i would like to buy Nvidia GTX 1060 (6GB). What's to think? ITS good option for me? or should i take Radeon or 1050Ti?

\n\n

Anyway thanks for any reply and have a nice day

\n", "Title": "Looking for PC upgade", "Tags": "|graphics-cards|desktop|processor|", "Answer": "

As you I would upgrade the cpu and the motherboard. I think your cpu is the cause of your low fps. I myself have a i7-6700k and GTX 660 ti and I can play games like GTA V (120 fps) and CSGO (400 fps) with good full hd graphics. Also video rendering and blender etc.. aren't lagging or crashing.

\n\n

i5-7600 is good for your use. For gaming alone it's not worth it but for your use it should be good. If you think that there is any chance that you someday want to overclock it I would take the K version. Price is almost the same on K as it is in non-K version. Motherboard does not really matter but take that one of the popular once.

\n\n

You also need new RAM if you are going to upgrade from 1155 to 1151. If your budget is not enough take only 8GB for now. But don't take too slow RAM. You might regret that later as it makes a difference on video editing and because combining different RAMs might cause problems.

\n\n

You did not say if you had a ssd but if you don't I really recommend getting one. I like video editing myself and gaming myself and with ssd I can really see the difference. Cheap ssd does not take much away from your budget if you buy your parts from good places.

\n\n

For future gpu don't take the 1050Ti. That is hardly better than 660 ti. 1060 is a good choice but if it too expensive Radeon should be also good for your use.

I have been researching on entry-level graphics cards for about a month and I have come down to four options, which I'm not sure how to finalize. The following are the cards.

\n\n
    \n
  1. Sapphire Nitro Radeon Rx 460 4GB OC [ $199 ]
  2. \n
  3. Gigabyte Radeon Rx 460 Windforce OC [ $126 ]
  4. \n
  5. ZOTAC GeForce GTX 1050 Ti mini 4GB [ $150 ]
  6. \n
  7. Gigabyte Geforce GTX 1050 Ti 4GB [ $149 ]
  8. \n
\n\n

The costs are more in my country (India) and hence can be substantially different from other retailers around the globe. Please advice.

\n\n

Note: I haven't provided any precise requirements because I felt that all the 4 listed cards fall in same generation and they all meet similar requirements - budget, mid-1080p performance, decent-good HEVC decoding/encoding, almost similar performance etc. And future proof is being not to invest anything on GPU for at least 3 years. Instinctive and experience based recommendation is what I'm looking for.

\n\n

Note2: My minimal requirements for the card is to setup an always on HTPC with onboard HEVC decoding and be able to play AAA titles at decent quality for the next 3-4 years. Budget is limited to sub-$200.

\n", "Title": "Picking the right future proof graphics card", "Tags": "|graphics-cards|", "Answer": "

Your question is borderline \"Primarily Opinion Based\", but I'll try to make my recommendation as objective as possible.

\n\n

Considering your $200 budget. Your best bet will probably be a GTX 1060 3GB (mini). You can find one like this card offered by Gigabyte. for about $185 on Amazon, or for about $195 on Newegg.

\n\n

Reasons for my Recommendation:

\n\n\n\n
\n\n

It can be difficult to determine how \"future-proof\" this card will be. However, if you plan on playing games with similar performance requirements over the next few years, you should expect similar performance. As for providing decent quality in gaming, this can be difficult to determine as \"decent quality\" is subjective.

\n\n

N.B.: You didn't mention the other components in your build. Before making your purchase, you should ensure that your PSU and motherboard are compatible and [ideally] you should check that your other hardware does not bottleneck your GPU selection.

On my motherboard I have a PCIe v1.0 x16 slot. According to Wikipedia, it's able to transfer at ~4 GB/s.

I'm thinking of getting a PCIe SSD (for example, this one), which is limited to ~3.8 GB/s.

\n\n

However, the SSD is made for PCIe v3.0 x4, which, despite also being limited to ~3.9 GB/s, poses a problem for me. Since it's only using 4 slots (hence the x4), if I plug it directly into my PCIe slot, it'll be limited to ~1 GB/s (or a quarter of the speed). Why? Because I have a PCIe version 1.0, and the SSD is designed for 3.0.

Is there an adapter that will take my PCIe v1.0 x16 slot, at 4 GB/s, and give me a PCIE v3.0 x4 slot, at 3.9 GB/s?

If so, could someone recommend one?

According to http://www.pcadvisor.co.uk/feature/pc-components/nvidia-geforce-gtx-1080-vs-gtx-1070-vs-gtx-1060-3640925/, the 1070GTX has a TDP of 150W. This is the amount of heat a component produces -- which with solid-state circuitry is conveniently the amount of wattage it draws, 1-to-1. Doubling that (for two of them), gives you 300W. If we assume that's all on the 12V rail (worst-case scenario), you're asking for 25A from your power supply. Your CPU has a TDP of 91W, and lets go absolute-worst-case scenario and say your motherboard is 89W to make the math easy. This is a further 180W of power draw, or 15A @ 12V. I don't know if it's all from the 12V line, but this is the worst-case scenario.

\n\n

A single rail (your PSU provides two) produces 30A at 12V, and a maximum of 540W @ 12V combined. Going from my worst case scenario, you are at 300+180W, or 480W of a maximum 540W. Antec quotes a 100,000h MTBF @ full load -- which means you can go bigger still. Your PSU can actually provide enough power for your CPU @ 100% load, several HDDs & fans, and a pair of stock-clocked 1080GTXs.

I came up with a project for which I'll need a couple of cameras and process their output ideally realtime or with slight delay (feature detection and tracking). Initially I thought about buying couple of cheap web cams, then I realized their framerate and resolution isn't good enough and drivers aren't generally good either. So I went online to look for some sensors and found this website digikey.com with a list of hundreds of sensors. But that only found a few items and from only 3 different manufacturers.

I have something similar for archiving and documentation purposes (BIM/CAD data for houses). There are some prerequisites you need to take into account:

\n\n\n\n

Mode of operation:

\n\n

As I wrote above, forget about opening the notebook in 7 years. Set up a periodic schedule once a year to start up the notebook (also have this procedure exactly documented in your printed out documentation).

\n\n

The bootup should basically show any pending problems. If you get reading errors, maybe some SSD has started losing data. It's better to know that earlier than later, because retrieval may still be possible than when you get to know 5 years later.

\n\n

You should never store the notebook with the battery plugged in. Also, the battery (Li-Ion) should be loaded only 70%. If you can get a notebook with LiFePO4 battery - get that. Life expectancy is 20 years.

\n\n

Your VM proposal of a \"life\" backup system is also important. Do it. It's another kind of redundancy. A \"hot backup\" contrary to what I've described above which could be perceived a cold backup.

\n\n

The notebook should also be stored in a safe place. A safe maybe, for the extra safety margin with temperature and humidity sensors (some capacitors tend to dry out) and keep environmental conditions in approved range.

\n\n

There is of course more that could - and in case of real mission critical data should (as e.g. geographical dislocation of the two notebooks) - be done, but the above should get you going.

I have two audio sources, both using 3.55mm \"headphone jack\" outputs.

\n\n

I have one set of powered stereo speakers.

\n\n

I need to connect both sources to my single pair of speakers. Ideally, I'd like to be able to hear both sources at the same time, but this isn't completely necessary. I ABSOLUTELY do not want to have to press a button to manually switch.

\n\n

I don't need anything fancy\u2014-no individual volume control or microphone inputs or anything like that. But I do want to avoid any significant loss of audio quality.

\n\n

How can I do this for under $25? Or if that's completely unreasonable, how can I do it for as little money as possible?

I have recently gotten back into online gaming after being introduced to Overwatch. I've found that in order to get the most out of the game it's important to be on voice. I have a pair of bluetooth headphones that also doubles as a headset which is what I am currently using to talk to my teammates.

\n\n

However I've run into two issues. The first is that the quality of the game sound and mic is not very good when the headphones are in headset mode and the second is that the battery has died on me a few times in game.

\n\n

The solution for this would be to get a wired headset in order to talk while in game, wired (USB or analog) provides better quality then bluetooth and usually doesn't consume any power. However, I like having a pair of bluetooth headphones that I can use to listen to music while I'm doing stuff around the house.

\n\n

Are there any headphones that support bluetooth and a wired option that also have a mic built in? I've been googling around but most headsets for gaming look to support wireless audio over wifi only. The closest I've come is these and I'm not sure the mic quality would be very good.

I want to buy a NVIDIA GTX 1070 GPU for deep learning tasks. The following GPUs are the candidates:

\n\n\n\n

The former is around 100$ more expensive in my country. I think the main difference is their cooling system.

\n\n

Are there any additional features that justify the price difference?

\n", "Title": "Comparing two GTX 1070 GPUs for deep learning tasks", "Tags": "|graphics-cards|", "Answer": "

The brand and cooling systems are NOT the main differences here, so let's break it down. I will now attempt a Venn diagram in bullet point format:

Specs shared by both the MSI and Gigbyte models:

\n\n\n\n

Specs specific to MSI model:

\n\n\n\n

What you are paying the extra $100 for is not just the cooling system, it's also the pre-overclocked card. You are getting a card with a theoretical maximum speed that is 76 MHz faster.

\n\n

Recommendation (TL;DR): If you have the extra money and want the little extra bit of power, go for it. But being that you chose the 1070 instead of the 1080, I'm thinking that little bit of power isn't very important to you, and probably not worth the $100 investment.

If you still insist on getting an amplifier for your headphones, you can get really any amplifier. Just make sure you don't go and max out the gain (I wouldn't turn that up too much anyway because it can end up amplifying a signal enough to hear some of that annoying white noise).

If I googled best Linux laptops in 2017 I came up with a list like:

\n\n\n\n

What use cases (except video editing, virtualbox, gaming) will break performance of a cheep alternative laptop like Acer Chromebook 15 CB5-571-C1DZ? What are your experience, when you need a upper class laptop in your daily life? Or can we say everything becomes faster on a laptop in the list above against Acer Chromebook 15, regardless which Applications you will run.

\n", "Title": "Recommendations for Linux Laptop 2017", "Tags": "|laptop|performance|", "Answer": "

According to the product page the Chromebook has a Celeron 3205U Dual Core clocked at 1.5 GHz. The other machines in your list (1, 2, 3, 4) start with Intel Core i5 processors of the 6th or 7th generation usually clocked about one GHz higher featuring Hyper Threading.

\n\n

Cnet says the Chromebook has M.2 storage, which is better than the typical non-upgradeable and typically slower eMMC found in many other Chromebooks. It would be nice if the RAM was upgradeable too, 4 GB are not shabby but not plenty either. I'd rate the slow processor as a deal breaker though because I had a similar Celeron stutter at 1080p video playback (on a smaller screen so scaling was also involved). So the comparably big screen may not be useful at all. You may argue that you are not the kind of person watching 1080p videos on such a device and I'd mostly agree, but if the processor is already under high load in this scenario and most of the time struggling to keep up with running a non-ChromeOS OS (like just opening XFCE's or Gnome's resource monitor) then I wouldn't want to wait for it to get its work done when I actually need to be productive. Also these are usually passive cooled devices, which may overheat and crash or just throttle down even more (to get no work done at all!?). Core m processors (soon to be rebranded as Core i3) are a bit better, but they also have unusual CPU spikes when just scrolling through a website in Chromium, which I haven't noticed on mobile or desktop Core i5 processors. For a device of this size a 3270 mAh battery is a disappointment and I wouldn't recommend buying a non-USB-PD charging Chromebook, all the newer ones come with USB Type-C as per Google's new requirements (it's said to be a huge advantage in educational institutions to only have one charging connector).

\n\n

N.B.: CB5-571/AURON_YUNA supports Coreboot UEFI payloads (not dual-booting ChromeOS this way though), but not all Chromebooks do, you'd have to use the legacy boot slot to boot an after market Linux distro.

\n\n

Regarding my experience, I have:

\n\n\n\n

Summary: I'd stay away from Celeron powered Chromebooks if you cannot live inside tmux or other specific, very trimmed down setups (GalliumOS is already very nice). A cheap small Chromebook as a non-primary device may be okay, but consider saving the money and buying a better equipped device for double the price. Such premium convertible Chromebooks with touchscreens and backlit keyboards are rare, hard to get and even more pricier at the moment here in Germany, but honestly save your money or go for the pricier Ultrabooks/Laptops while we wait for more competitive devices. I found Chrome Unboxed to be an interesting read on this topic.

\n\n

Edit: Some usually bring up video editing and make it sound like something unusual, resource heavy thing that you don't usually do unless you are an artist or trying to make money off of Youtube but just set the playback speed of video above 1x and look at how that changes resource consumption or just quickly seek to the right timestamp in a video. It's also not completely absurd to watch video this way see PAL speed-up.

Everything there's pretty self-explanatory except for the far right column. It's an estimated TCO per unit memory speed per year including cost of power in Ontario. So, you can probably just ignore it if you don't live in Ontario. In fact, you can probably ignore it even if you do.

\n\n

Anyway, the GB/s/W is the dominating factor when it comes to electrical bills. By that measure, the Radeon RX 550 is winning, but you'd need quite a few of those in a single system to really reap the benefits.

\n\n

In the rest of my build, I'm assuming that mining throughput scales more or less linearly with additional GPUs. If this is true, communication between GPUs isn't necessary (i.e. crossfire support unneeded) and it doesn't matter too much what the PCIE bus speed is. I'm assuming linear scaling because I think this is how it works on the network at large, with eth generation scaling linearly with number of miners. Is that a sound assumption?

\n\n

Anyway, to those who have actually done this in real life, am I at all close here? Am I missing anything critical?

Instead of relying on theoretical considerations, it is wise to take into account real measured hash rates. Fortunately, since many tech sites have taken upon themselves to do these benchmarks, and publish the results, you do not have to actually purchase the cards to get hard numbers for yourself. These numbers can reveal certain unexpected deviations from the theoretically expected hash rates: For example many miners have found an unexplained decrease in hash rate on the newer Polaris GPUs at larger DAG sizes. (1)(2) This can mean trouble over the long term, as those cards become obsolete for mining before paying for themselves.

\n\n

Looking at the benchmark results, we can immediately see some interesting figures. The older R9 390/Xs perform superbly, and do not appear to degrade at higher DAG sizes. It's somewhat surprising to see the GTX 1070 above the 1080, something we would never know just looking at the 1080's higher core count and memory bandwidth. It appears that GDDR5 has superior latency characteristics for mining than the GDDR5X used in the 1080 (Another reason spec sheets do not tell the whole story: latency information is missing). The GTX 1060 also performs adequately, though for future proofing, the 6 GB version is a must.

\n\n

Overall, due to the higher power consumption and lower availability of the older Radeon cards, although the R9 390 is a viable candidate, I do not heavily recommend it. Essentially, the decision is between the 1070 and the 1060. The choice between the two essentially boils down to how much capital you plan on investing into your mining gear. Since for a more expensive GPU, the rest of the system makes up for a smaller proportion of total costs, I would recommend the GTX 1070 as a first choice and the GTX 1060 or R9 390/X GPUs as secondary options.

I'm looking to buy a smartphone in the U.S. that has NFC and clean Android (i.e., no bloatware). I'm also looking for a phone that is reasonably priced and that has a decent processor. I know these specs are rather vague, but I was thinking something along the lines of the moto G5. (Hopefully that will make it a bit clearer.)

\n\n

Unsurprisingly, my first impulse was to buy the moto G5, until I found out that for some reason it doesn't come with NFC only in the US. So now I'm trying to find similar phones with similar prices and specs, which is hard because the Moto G really does a very nice job of making good affordable phones.

\n\n

So far the only thing that came close were the new Nokia phones that were announced, but I still don't know the price and the specs don't seem to be as good as the Moto G specs. Also, although it should be released in the second trimester of 2017, no news as to a US release date.

\n\n

Cheers.

\n\n

P.S.: Another alternative is to somehow buy a Moto G5 with NFC in the U.S. via some non-shady path, but I'm unaware of how to do that.

Alongside the option that @Jeff mentioned, There is the Blackberry Priv for only $219 new off eBay US.

\n\n

This phone's bloatware is about as existent as Motorola phones. Also, defining bloatware for blackberry devices is somewhat complex. These devices do not show bloat in any form such as Samsung, instead the bloat is really slight overlay tweaks, which can be customised to a certain extent.

\n\n

Performance wise, the Priv is one of the best phones I have had the pleasure to use, It just feels so slick and interruption free. It sports NFC too.

\n\n

One benefit is the lovely screen, and QWERTY keyboard that sits behind the screen, sliding up and down, and doesn't really add to the psychological feeling of bulkiness. The phone is only 9.4mm thick, actually .1 mm slimmer than the Moto G5.

\n\n

I would definitly recommend the phone, and even more recommend trying one out if you can.

I'm helping an older coworker upgrade his PC, he has a HP Compaq with the following:

The upgrade is fine; the 8400 GS appears to have great reviews on Amazon.

However, with an increase in use of cloud services, I doubt that the 1 TB of space will be used at all; maybe 100 GB at the most, since you said that what he will be doing will be pretty much just browsing.

I have the Dacuda Pocketscan which as previously a successful Kickstarter project.

\n\n

It fits most of your requirements. Most, because being a hand-sized item, the power button is on the small side, about Pez candy size. The begin/end scan button is the larger round button on the top. Results are good, although most of my scans with it are newspaper quality and picks up the dark on the flip side of the paper. It's not the scanner that's poor quality, it's the paper.\n\"enter

\n\n

This is the result of a scan of a day-to-day single page calendar, with better quality paper.

\n\n

When the scanner is powered up, if the i-Device is turned on and the app installed, it takes the signal and asks permission to start, reducing the need to find the app on the device. Once permitted, pressing the button on the scan device begins the scan.

\n\n

It does require reasonably steady hands and the ability to recognize overlap areas which are used to register previous passes of the scanner.

The age of the user and tiny button may disqualify this item.

Some SSDs are thinner than some HDDs so they come with a spacer. Any non-electrically-conductive packing would do if you find the SSD is not held firmly, but I do not expect that to be a problem as they normally use four screws to hold them in.

Not gonna get far with an attitude like that, but I guess I'll tell you again that what you're looking for doesn't exist. It's impractical to a level where trying to produce and market a product that fills your requirements would sell one unit, and that unit would be sold to you. There is no keyboard that has dynamic displays that would change in response to stimulus from the Linux OS. Keyboard manufacturers have trouble getting little LED screens for \"gaming\" keyboards to play nicely with AAA software titles on Windows; thus, there's definitely nothing that exists and even if it did you'd have to build all those interactions into your Linux distro yourself. Here are the options that I see available to you:

\n\n
    \n
  1. Get a programmable board with different presets of keybindings. You may have a tough time finding something that works for you though, because a lot of these boards tend to be smaller and thus the multiple inputs per key scale as the number of keys gets smaller. If you look at an Anne Pro mechanical keyboard, for example, it's got 4 preset key combinations and one of those can be programmed as any layout you like. It's also got a ton of commands per key because it's a 60% size board. It is wireless but it's bluetooth, which I know you said you didn't want. Unfortunately almost all wireless keyboards that aren't $20 use bluetooth, especially the ones with the kind of programmable features you're looking for.

  2. \n
  3. Get two full size programmable boards and program one board for all of the primary key inputs and then the other board for all the secondary inputs and then buy custom keycaps for each board with only the symbol you want printed on them.

  4. \n
\n\n

It sounds like you \"need\" option 2 because this issue is driving you nuts, and I get that. It sounds like what you \"want\" is something like option number 1, but that's never going to fulfill all of the standards you want to meet. You're either going to have to make a compromise here or get creative beyond my capabilities. Best of luck.

I am using the same thing on Linux, but it should not matter. I just install whole system on USB flash and setup in BIOS to boot from USB first.

\n\n

Now it finds the USB on start, boots from it, sets the whole system, connects to net and does the usuall daily tasks. I can connect remotly, setup encription and connect internal hard drives encrypted, if I need so.

\n\n

Those internal HDDs contains just5 encrypted data, nothing else, the USB flash contains the full system and can be used to rescue any USB bootable computer (nearly any nowadays).

\n\n

As flash is not good for too many writes, I load as much as possible of the system to memory at start and I set the logs to RAM disc entirly, so th USB can be read-only. Takes more time to boot (USB is always slower than native connection), but I do not care. I can get the system anywhere else leave the computer with encrypted data discs only, not being able to boot. I can use the flash on any other computer to get my system working.

\n\n

In Windows case it would mean to install the windows on the USB only (or start with some rescue flash and expand its content, then maybe copy it to USB disc. The disc probably needs to be market \"bootable\" and you need to set the computer BIOS to boot first from remote media - either as default option, or as backup option and do not make internal disc bootable, or just press propper key on boot to select boot media from list of aviable devices.

\n\n

As I do not use Windows for many years (from when XP was hot new), I cannot provide step to step instruction, but maybe Windows are not so bad, that they would not enable \"rescue system\" to lay on USB media and to be customized ...

The answer is that it depends. If the one processor is faster than another, you can definitely undervolt the processor, or underclock it to slow it down. It would be dependent on how much you undervolt or underclock the processor, however. You might also want to note that you would want to make sure that your motherboard can support overclocking so you can ensure that you can actually mess around with the processor states and voltages.

\n\n

Also note that the power consumption scales linearly with frequency and quadratically with voltage. So you can also reduce the frequency on a cpu state to lower power consumption as well, but it is more effective to decrease voltage because it has a squared relationship with power consumption.

I am not sure \"deadbolt\" is the correct term for what I am looking for. I am searching for the metal piece on the side of doors that extends to lock it, but one that can be controlled electronically (with Arduino).

The thing on the right of this video is exactly what I want, but I can't seem to find anything like it.

Does anyone know where I could find one of these, or at least what this would be called?

I am also open to other setups to lock a door, but the part I described above is preferable. It doesn't need to be very secure or anything; I mostly just want to make use of an RFID scanner.

I'm a first time computer builder and I want to know is every thing in this build compatible. -thanks

The Intel Pentium G4560 is a castrated i3 and hardly slower, maybe 10%. The Z-Board is a waste of money, especially if you do not overclock.\nRAM seems legit on first glance but you lose dual channel which needs 2 RAM sticks to get slightly more performance.\nDon't buy cards for around 200\u20ac or more with only 3GB Video RAM, bad choice, rather go AMD with 8GB (470/570, 480/580) or Nvidia 6GB 1060.\nYou have to check if your stuff fits in the case.

\n\n

Budget? The goal is to build a gaming PC, right? What games? Other tasks which the PC has to master? An SSD instead of an old HDD would greatly reduce all of your loading and startup times, makes the PC much more responsive but gives you (almost) nothing for gaming.\nMaximum and desired resolution (which is mostly GPU work)? Do you have some old hardware left? Etc. etc. Google and other tech/PC sites are a major help if you search a bit more, the forums there might also have guides which might answer your questions.

\n\n

Edit: compatible? Seems so (if it fits into the case which it probably does but I don't know). Ahh and the mentioned i3-like pentium costs like half of the i3 or maybe even less.

I am looking for a cheap tablet that I can use with a stylus for primarily marking up pdfs.

  1. Ideally, it would have a decent amount of RAM so it would not have to reload sections of the PDF on larger documents.

  6. \n
  7. I'm not married to any operating system, the functionality is the larger concern. Windows would be nice because that is what my company uses so I could use their software license pool for the PDF software but every OS has something similar.

  8. \n
  9. Size is not a major concern. Probably at least a 4x6 screen so I am not constantly trying to zoom in and out of the document but beyond that, I can manage.

I am not from India, and INR prices don't translate very well in my mind, but this seems about in your price range.

I am not sure that this would be available to ship to you (since I am not from India), but it seems that Flipkart is pretty big out there, so hopefully it is.

Anyways, this is considerably less powerful than the laptop you posted, but seems to also be somewhat cheaper. The CPU is the same, but the GPU is a 1050 (not Ti) instead of a 1060. It has 8GB of RAM instead of 16GB. I have a laptop with similar specifications to the one listed (better only in terms of RAM), and it performs very well.

is there a device which converts the incoming lan signals into wifi signals?

\n\n

The apartment only has a fixed network ip with a predetermined gateway and DNS. One needs to give this static ip, netmask and gateway in the network configuration of the computer and it works.

\n\n

But I would like to use smart phones to access the network. Hence the static settings should be done in the device ( maybe it is is called an lan to wifi adaptor ) itself . Ofcourse, I do not want an expensive ADSL or DSL because I do not need the modem functionality.

Also, it would be great to know how this network device works i.e how does it give the IP addresses to the connected devices - may be using NAT?

But the problem there is, that the static IP provided by the external router is class B ( 134.x.x.x ). If I enter this static IP into the FritzBox's Routers configuration and activate the DHCP server of the Fritzbox to provide IPs ( Class C - 192.168.178.x ) that would distribute the IP's to the connected devices, the Fritz box complains a conflict between the Class B incoming IP and the class C Fritzbox's DHCP IP.

Both of these boards support my current FX-8350; this is relevant because your CPU's TDP is 125W according to the spec sheet on AMD's website, as opposed to 150W like you stated in your post. The FX-8350 also has a TDP of 125W, so both of these boards should support your CPU.

Careful on your RAM by the way. Whatever board you buy, you need to grab a .pdf of their mobo manual and make sure that your current RAM kit is listed in there for compatibility. Not every RAM kit is manufacturer-tested, so unless you want to end up buying new RAM and waiting another two weeks for shipping after a frustrating Saturday afternoon of troubleshooting, check the literature and save yourself the hassle. Best place to start looking is just to look up your old motherboard, and find the slightly updated version of it.

I would start by saying that, as a person who had little knowledge about building a computer, but ended up doing exactly that, building is definitely the route i would take when building a Virtual Reality capable machine.

\n\n

Couple of reasons for this:

\n\n\n\n

With that out of the way, Oculus actually have a recommended list of computers here on their site. One that sticks out to me in the kind of price range you are mentioning above is the Lenovo IdeaCentre Y700.

\n\n

The first in the range of these models actually starts at $649, which should have plenty enough power to run VR games.

There is actually a reason why I would recommend this over your $650 Cyberpower PC, (some people are not going to like this), but it has a NVidia GPU. In my experience, most (not all) VR experiences run much better on NVidia cards, but don't hold me to that as I have no solid or documented proof, I have tried both and I personally preferred the NVidia experience overall.

\n\n

Another point to mention is that this computer sports an Intel processor, but that AMD vs Intel is a very contentious topic, and I don't feel it is my place to start an argument on that. (I recommend Intel by the way :p)

I threw together a price on PCPartPicker, but for the ease of purchase and performance, I couldn't recommend the Y700 more, it seems like a really good deal.

I am looking at getting a CPU from the following list:

\n\n\n\n

Here is a comparison of these CPUs on the Intel website for your convenience.

\n\n

I will be building a small form factor desktop GPU workstation (AI, ML, Computer Vision development) with an NVIDIA Quadro P600. I've narrowed it down to the CPU's in the above comparison. They are all pretty similar in price and specs, but what would you all choose if it were you?

It depends.

If you want to use ECC (error checking and correcting) RAM, you have to get the Xeon. If you don't want to use ECC, which is more expensive than normal RAM.

\n\n

If you don't want to get your own CPU cooler, but rather want to use a stock one, get the i5-7600 because it is the only one from that list that can be shipped with a stock Intel air cooler.

In any other case the i5-7600K is the superior choice.

I am looking for a single modem/wireless router (or just a wireless router) that can create/share three Wi-Fi networks, each of which are to separate connections?

\n\n

See below for context.

\n\n
\n\n

My requirements are such that I need to have a minimum of three Wi-Fi networks available in a particular building. More specifically, these networks would be as follows:

\n\n\n\n

The catch is all three Wi-Fi networks need to be available simultaneously, each with their own passwords so that the VPN 1 network can only be accessed by its two users and likewise the VPN 2 network only accessible to its one user. Wi-Fi Network 1 can be accessible to all, but still needs to be secured.

\n\n

The two obvious options are:

\n\n
    \n
  1. have an ADSL modem/router connect to the internet and wirelessly share this, and then have two separate individual routers physically connected to that via ethernet to connect to and share their respective VPNs, or
  2. \n
  3. have an ADSL modem/router connect to the internet and wirelessly share this, and configure each individual device (computers, smartphones, tablets, etc) to connect to their respective VPNs (using OpenVPN for example).
  4. \n
\n\n

However, I'm looking for a more elegant solution as multiple devices need to connect at various times and none of the users are tech savvy. In other words the best user experience would be to just have all three networks available around the clock and for users to just switch Wi-Fi connections on their devices as required. Also, having multiple modems/routers is overkill as the building is not that big and at most we're talking six simultaneous users.

\n\n

If no single modem/router (or even just a router) can create/share three Wi-Fi networks, then what is the closest solution? For example, with Option 1 above, is there a router that can be configured to simultaneously connect to and share two separate VPNs so that I only need the one router connected to the ADSL modem/router rather than having two?

\n\n

Note: - The Wi-Fi networks do not all need to be on the same band (e.g. one could be on the 5GHz band and two on the 2.4GHz band, etc).

\n\n

Finally, I am also open to other suggestions to achieve the overall setup.

With DD-WRT, anything is possible! Try a live demo here. Note that the demo is outdated and many features have been disabled on it.

\n\n

DD-WRT is a custom firmware available for a variety of routers that adds many additional features such as supporting multiple different wireless networks connected to different vlans, hosting a VPN server, and much, much more! There are other solutions such as Tomato, OpenWRT, and LEDE, but I haven't used those and I know for a fact that DD-WRT does what you're asking.

\n\n

Simply take a router that works with DD-WRT (compatibility can be checked here, see [] for a list of current recommended routers) and flash DD-WRT onto it (A general installation guide is available here, google for a router-specific guide as each router is slightly different.)

\n\n

Warning! incorrect installation of DD-WRT can Brick your router, so be careful and follow a router-specific installation guide.

\n\n

With your fresh DD-WRT head to 192.168.1.1. There you will be prompted to set the web interface's login info. Do so and head to the Wireless->Basic Settings submenu. Here you can edit the default SSIDs and add more under the \"Virtual Interfaces\" list.

\n\n

You use different VLANs for separate networks, but I'm not familiar enough with networking to tell you how to do that.

The other answer was very helpful, and it opened up a whole set of options I didn't know about. Unfortunately most options are keyboards that are either custom made or have to be ordered internationally. This would mean a lot less favorable return conditions (if at all) should I not be satisfied. So I looked for something I could get in my own country first, where you can almost always return stuff within 2 weeks for a full refund.

I have been using a Raspberry Pi 3B as a workstation, connected to an HDMI monitor and keyboard and mouse. I use it for a variety of tasks, as a general-purpose computer.

\n\n

With accessories it was just over $60. I already had the monitor, keyboard, and mouse.

\n\n

It actually works well as a workstation. I can browse the web as long as I don't open too many tabs. It only has 1 GB RAM, period.

A bigger concern is the limited lifetime of using the SD card as primary storage.

The device SEJPM mentions in his comment would fit you requirements and is offered by a variety of manufacturers to complement their laptop products as well as 3rd party computing devices. DisplayLink is the company that makes the chips that enable the video functionality. I have used such a device before and I still have it, though I have a problem with calling these devices docks as these are not traditional docks but big dongles with 45W PSUs and they can get quite hot.

\n\n

They get the job done quite reliably and the manufacturer offers drivers for a wide variety of platforms, even Linux (they didn't offer drivers for their 3.0 devices at first, but this has been solved a few years back). My older Thinkpad T530 from 2012 had no problems displaying 3 1080p videos with this and my 2 Dell 1080p monitors connected at home.

\n\n

Edit: In theory everything should work fine, but I did some testing with the devices I have here in the office (1\u00d7Dell U2512H, several Dell U2412M), turns out that you should check when getting one of the DisplayLink devices and which one in particular exactly as dual 2560\u00d71440 may be too much for Gen 3xxx devices like mine, devices with 5xxx chips may support such high resolutions older ones were probably made to just support dual 1080p or 1200p.

The U2512H is detected on my Linux machines with recent drivers at proper resolution but as soon as I plug one of the other monitors in its resolution drops to the highest one supported at this data rate (similar to HDMI 1.3 only capable devices, though I connected the bigger monitor to the DisplayPort output). You can set the refresh rate to 30Hz to still drive the monitor at full resolution, but I don't recommend that. DisplayPort chaining is not supported on mine, so a third monitor will just be a clone.

Also DisplayLink solutions don't support night modes as offered through f.lux, Redshift and some recent desktop environments.

I'm building a new system and I want to keep it as quiet as I can without degrading performance. I do plan on doing some moderate overclocking. I am planning on using an all-in-one CPU liquid cooler. Am I better off getting one with 3 120mm fans for the extra radiator surface area or will a smaller radiator with 2 140mm fans still keep the system plenty cool and quieter?

\n", "Title": "Should I get a radiator with 2x140mm fans or 3x120mm fans", "Tags": "|cooling|", "Answer": "

If you only plan to only cool your CPU with the AIO cooler, I would say 2 140mm fans will keep your CPU plenty cool and be quieter then 3 120mm fans. However if you plan to cool your GPU as well, you will want the 3 120mm radiator. Regardless of the 2 140mm or 3 120mm radiator, the kind of fans used on it will make all the difference.

\n\n

You can very easily get 3 120mm fans that are considerably quieter then 2 140mm fans, however having less fans will make it easier for keeping things quiet. From personal experience I have found that very rarely will any cooler come with high quality fans. I usually buy fans regardless if the cooler comes with them or not, that way I can make sure the cooler will be as quiet as possible while still being able to provide good performance.

\n\n

For radiator fans, and case fans in general, there are 3 things to keep in mind when choosing a fan - fan speed, noise level and static pressure. Check out this video for an explanation about static pressure vs air flow and why static pressure is important - Static Pressure vs. High Airflow Fans As Fast As Possible

\n\n

I have personally had extremely good results from Noctua fans, they have a low sound level, good performance and a long life. For a 140mm radiator fan I would recommend this fan - Noctua NF-A14 PWM, if you went with the 3 120mm radiator I would still recommend the Noctua brand - Noctua NF-F12 PWM

\n\n

Also, it is important to keep in mind that ultimately what is important is not the amount of noise that the fan makes but the amount of noise you hear. Things like where the fan radiator is placed, or what it is placed in, can go a long way in reducing the amount of noise you here. One such method would be to place the radiator in a box lined with noise suppressing foam as a way to decrease the noise that you hear.

\n\n

It is also important that your computer fans are setup so the air flows as efficiently as possible, such as fans in the front are intake fans and the fans in the back and top are exhaust fans. Another thing to keep in mind if your bios offers this feature is to set the fans to variable speed, this allows the fans to only increase their speed (noise) when the computer needs them to.

Im a big fan of HP these days.. Used to be a big Dell person but they tend to offer less bang for your buck these days.

\n\n

If your looking to save a few bucks my thoughts would be to scale down the Hard Drive to a 256GB.. That should provide enough space for your core environment. You can always buy cheap external hard drive (or 2nd Internal if possible) later on if it turns out you need to. My set up is to only have core software on the main HD and save projects externally.

\n\n

Anyways, if that concept is ok with you, then here is one that I've had my eye on..\nhttps://www.newegg.com/Product/Product.aspx?Item=9SIAADF5MK0383

Truthfully, \nYou could probably drop the RAM down to 8 GB and still have a pleasurable experience programming. \nhttps://www.newegg.com/Product/Product.aspx?Item=1TS-000D-01GH8\nThis one is configurable, I would take the I7 2.7GHz, non touch, Windows Pro, 256 GB SSD, 8GB RAM.. Thats a pretty good value for $869 and i think HP is doing a pretty good job these days.

\n\n

One last thought, AMD is making great processors as of late. While their newest line of products hasn't quite hit the market yet (they will be awesome) they still make great products for less then Intel.

I have a 3' (1 meter) tall plastic gate around my yard. I would like to automatically close it with my Arduino or Raspberry Pi. Not by remote control - I just want it to detect that the gate is open, wait a few seconds, then close it.

\n\n

I figure I need 2 things:

\n\n
    \n
  1. A sensor to let the Arduino know if the gate is open or closed
  2. \n
  3. A mechanism whereby the Arduino can close the gate.
  4. \n
\n\n

I feel good about my ability to find and implement #1, but I'm not at all sure about #2.

\n\n

The gates curently use this kind of latch:

\n\n

\"enter

I figure to force-close it the mechanism would need a fair amount of force (I'm not sure how to measure or quantify this). OTOH to close it by first pulling back the latch, then pushing it closed and releasing latch seems like it would be much more complicated (?).

\n\n

I'm also open to some different sort of latch to work with the robotic closer. Maybe some magnetic latch would work, but it would have to be strong enough to keep my 25lb Sheltie dog from opening it.

The thing you you are looking for is called a Linear Actuator http://amzn.to/2uWRIjV

Depending on the strength of linear actuator you get, you might not even need a latch. \nYou can have the Arduino power the linear actuator until it senses the door fully closed or open. When it is not powered it will hold its position.

I have been on something of a quest for something which I am finding to be a very elusive piece of equipment: a Bluetooth headset that works well with Windows.

My Windows 10 PC has an onboard Bluetooth module that uses drivers from Windows Update. Windows 7 did not have these drivers, so while running Windows 7, I had a whole different set of issues with external drivers.

What does work well mean?

\n\n\n\n

Unfortunately, no headset manufacturer advertises anything about these features, except occasionally the charging interface, so essentially, I have to purchase a batch of headsets, and then return them all because they all fail at least one of these conditions.

I'm looking at getting a third monitor for my PC. I have an R9 380 and i'm currently using both DVI outputs. According to the AMD EyeFinity FAQ:

\n
\n

1: The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.

\n

2:The third (or greater) display must be connected to the graphics card via DisplayPort.

\n

3: If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it. DVI to DP adapters can be had for less than $30 USD.\nEvery family of GPUs supports a different maximum number of displays.

\n
\n

The monitor I have chosen has DVI input, and I have been given a DP to DVI adapter, but I don't know if it's active or passive. The reason this matters is because i've read that EyeFinity will only support it if it is using an active adapter, and then something about having only two streams??

\n

The adapter i have is Dell 0KKMYD and i can't find out anywhere whether it's active or passive. I can't see anything on the adapter itself without opening the packet and I don't want to do that just yet in case I have to return it.

\n", "Title": "Is this DP -> DVI adapter active or passive?", "Tags": "|video-adapters|", "Answer": "

I cannot say for sure whether your adapter is an active one or not, but my strong assertion is that it is not. My reasoning here is that feature is usually a selling point and they typically are priced higher as well. You can try it but I doubt it will work properly.

\n\n

Now I did verify that you need an active adapter to do what you're trying to do with Eyefinity, and I was able to find this: \"Cable Matters Gold Plated Active DisplayPort to DVI Male to Female Adapter - Eyefinity Compatible\". That particular one is on sale on Amazon at the moment, but you can definitely look around for other products if you need other features (cord length, whatever else) or want to hunt for a better deal. Just make sure the words active adapter\" are clearly spelled out on the product page.

\n\n

As for this part:

\n\n
\n

The reason this matters is because i've read that EyeFinity will only support it if it is using an active adapter, and then something about having only two streams??

\n
\n\n

I think what you're talking about doing here is called Multi-Stream Transport, a technology featured in DisplayPort 2.1. It allows you to run multiple monitors from a single DisplayPort output, but does have limitations depending on your overall configuration. From what I can tell you don't need to make use of that feature to accomplish your objectives here.

\n\n

One more thing just to clarify EyeFinity; that software is only designed to play games and other fullscreen applications across multiple displays, so you can game in ultra widescreen formats and whatnot. You don't need EyeFinity to use your operating system or to do single monitor gaming, so I wanted to make sure that it's clear here that EyeFinity is not a necessary technology for standard computer use.

I have been trying to figure out what kind of watt range PSU should I aim for my X370 pro gaming motherboard.

\n\n

I ran into a weird range of watt usage on different calculators.

\n\n

My setup is this:

\n\n
AMD Ryzan 1700x at default speed (no OC)\n4x 16 DDR4\nDual Radeon RX 570 and SLI/CF (no OC)\n2x M.2 SSD\n2x SSD\n2x monitor LCD 20 inch\n
\n\n

Now Outervision says go for about 491 Watt or so. Which seems very low considering all things!

\n\n

While Newegg doesn't seem to have put in RX 570 value in yet porperly so I replaced with RX 480 and it comes out at 696 Watt.

\n\n

Evga power meter says 600 watt which undercut Newegg's estimate.

\n\n

I am going to not setup all of this right away now and I may eventually upgrade to this later. For example at first I will only have one RX 570 GPU, fewer SSD more mechnical drives, and less RAM until I can afford to upgrade those.

\n\n

So with all that in mind what kind of watt range should I aim for?

\n", "Title": "X370 motherboard: Power Supply Usage", "Tags": "|power|", "Answer": "

Motherboard, ssd, and ram are all negligible wattage. I usually group them and say they use 100 watts max as computer parts are very efficient these days. But for the sake of calculating.

\n\n\n\n

Therefore you only need 451 W under max load. So you really only need a 550W powersupply. You could also get away with a 500W quality PSU as it's most likely your system won't be at 100% full GPU, CPU, SSD at any given point.

\n\n

I should note that, you should probably look at getting the rx580 or rx480 instead of trying to crossfire weaker cards. Vega is also around the corner if you can wait. Crossfire has a slew of problems, and spotty game support. It's better to get a single powerful card.

\n\n

I am somewhat bit lost on figuring out which memory that motherboard does support.

\n\n

On one lines it say \"- Supports DDR4 3200+(OC)/2933(OC)/2667/2400/2133 ECC & non-ECC, un-buffered memory*\"

\n\n

I have a quick installation guide booklet that say the same thing about 3200+(OC).

\n\n

Yet the following table only list MHZ up to 2667. I may be misreading the table.

\n\n

I talked to the computer department manager at Fry's Electronic (local DIY store for PC). He said go for 3000 MHZ because that is the motherboard clock rate.

\n\n

I went to G.SKill website RAM configurator it only shows support for 2133 MHZ to 2400 MHZ for x370 pro gaming MB.

\n\n

So my question is the 3200 listed overclocked to THIS amount or by default at 3200 and can overclock above that?

\n", "Title": "ASROCK Fatal1ty Motherboard X370: Memory support", "Tags": "|memory|", "Answer": "

Your motherboard can run any of the listed RAM speeds, but the extra speed will not be utilised if you do not use Extreme Memory Profile (XMP), leaving your more expensive purchase of faster RAM a useless investment.

\n\n

Due to this, If you are not thinking of modifying your BIOS settings, I would recommend choosing which ever speed of RAM is the least expensive in the range/brand you are looking at.

\n\n

For example, Corsair Dominator Platinum 2400Mhz is actually more expensive p/gb than 3000Mhz, even though some of the customers of the 3000Mhz product won't use the XMP option, the price is better because uninformed PC enthusiasts buy more of the faster RAM, as it seems more beneficial.

\n\n

The answer to your question is that the RAM is clocked at the speed listed, but to take advantage of that speed, you will need to enable the XMP option in your BIOS menu.

\n\n

OC means that the memory controller on the motherboard is overclocked when using 2933 or faster RAM, such as the 3200Mhz products.

As your TV is most likely HDMI only, getting a display-port to hdmi 2.0 adapter is fine as that provides plenty of bandwidth for 4k60.

I recommend using Display-port to hdmi 2.0 for your TV, and using DVI to your monitor so you don't have to switch between the two physically. If not you can just continue to share the hdmi connection from the display-port adapter.

Any recommendation?

\n
\n\n

Essentially, anything that has a Nvidia Geforce GTX 1070 or GTX 1080 will work for you. However due to your budget, finding a 1070-based model is more likely. The other caveats that you have to look out for are the 16GB of RAM that you specified, the SSD and that the CPU (most likely an Intel model) has HQ or HK at the end of the name and not U, because the latter would indicate a dual-core CPU limited to 28W or 15W power-consumption as opposed to a quad-core at 45W. Any laptop that satisfies these above constraints should work.

\n\n

Beyond that, note that you probably want to clean the fans every now and then (1x a month if you can) to make sure the air can flow and cool the system properly, so that you don't get reduced performance or sudden heat-caused shutdowns.

\n\n

Because I have to, I'll make a generic recommendation fitting your budget:

I am to purchase a laptop today. I have narrowed down to 2 choices.

\n\n\n\n

The prices are almost the same. The Acer has a 128GB SSD in addition to a 1TB HDD. But I am willing to compromise on that IF 1050Ti with 8 GB RAM will give me substantially good performance compared with 1050 with 16GB RAM

Both the machines are upgradable to the same extent.

Now, Acer comes with the higher specs in ram and SSD. Which extremely reflects your performance.

Now buying is dependent on pricing of the machines. If Acer comes at the same cost of dell or slightly higher or lower then simply choose the Acer blind folded.

Because 8 gig stick and a 128 SSD disk sums around INR 11k in India. Which is really a big amount.

From the motherboard specifications:

Dual-Channel DDR3 2200(O.C.) / 2133(O.C.) / 1866(O.C.) / 1600(O.C.) / 1333 / 1066MHz

Does O.C. mean it will gracefully fallback to 1333MHz if not overclocked?

Please see my accepted answer here for an overview of XMP and OC in relation to memory.

This Corsair Vengeance Pro DDR3 memory is probably a good choice for you. It comes in varying colors, which are all roughly around 150 EUR, or the Red version, which is 130 EUR.

This is the RAM that I actually have in my personal machine, and I have never had any issues whatsoever.

However, if you are set on purchasing the HyperX brand, then take the faster RAM speeds incase you want to use the XMP functionality at a later date.

I am looking at buying a laptop for uni. Most of uni stuff won't need very good specs but I also want to play a few games on it. The laptop I am looking at has a choice of Intel Core i7-7500U 2.7GHz or Intel Core i5-7200U 2.5GHz processors.

\n\n

It costs \u00a350 more for the i7, so my question is it worth it, and also if the newest intel processors are worth getting (I believe the 2 listed above were released in autumn 2016, and there have been more released earlier this year- https://en.wikipedia.org/wiki/Intel_Core).

\n", "Title": "Choosing an Intel processor (i7/i5)", "Tags": "|laptop|processor|", "Answer": "

In general if you can afford the \u00a350 more and it doesn't hurt much then you're going to get this much more performance, or let's say \u00a325 worth more performance if you want to be a bit more critical about Intel's pricing model.

\n\n

Here is a comparison of both models on Intel's site: https://ark.intel.com/en/compare/95443,95451

\n\n

There is just a difference in clock speed, but if you have workloads where a little extra performance matters and you can process more data in the same mount of time or get work done a tad quicker then that may be worth \u00a350 and depending on the maker and model the resale value may be a bit higher (well, I doubt it is in this case, I was thinking of Macs, ProBooks and Thinkpads). It won't make a notable difference with regards to gaming, authoring office/tex documents or compiling typical student programming projects. Workloads like complex/slow video/image analysis and encoding or compiling lots of big software projects (like a lot of Linux packages from source) will benefit a bit.

\n\n

The chassis looks fine from what I can tell, there should be little risk that the faster processor overheats and becomes slower than the other chip as has happened on some bad (ultrabook) designs in the past.

\n\n

If you are looking for the best performance and you can wait a little longer than you may want to look for the recently announced Intel 8000 series processors. The iGPU was re-branded from HD to UHD but is mostly the same (expect only very tiny refinements, if at all) but all of the announced models have 4 cores and 8 threads instead of 2 cores and 4 threads as the i5/i7-7000 series mobile processors have. But you will have to wait a few weeks or probably months for these to be available in updated products and the initial prices will be higher than these offers for a while.

My father has about 20-25% vision impairment (with eye correction) and I would like to ask you about a monitor which could make his life easier (avoid sitting too close and straining eyes too much).

Budget: up to $1200

\n\n

Do you have any recommendation on that?

\n", "Title": "Monitor for vision impaired person", "Tags": "|monitors|ergonomics|", "Answer": "

Couple things at play here, so I'll try to offer what I think would be the best comprehensive solution.

\n\n

First, you want a 27-30\" panel minimum, as far as size. It will allow for the monitor to be placed at a healthy visual distance without reducing how much area it takes up within his visual field, similar to how a 50\" TV looks \"smaller\" when it's mounted on the wall 10' away from you. You also want that extra screen space to be able to adjust any accessibility software.

\n\n

Examples of accessibility software for Windows would be the native Narrator software, NonVisual Desktop Access (NVDA) which is free open-source software, or Window-Eyes for MS Office or whatever the equivalent is called now. There are other options out there as well if none of these work for your dad.

\n\n

Depending on if and how you implement any zoom features to enlarge text, resolution might come into play. If you're going to enlarge text to 150% or larger, I'd recommend a 1440p display over a 1080p. My reasoning here is that as you enlarge text the lines might become blurred or altered due to the ratio between the desired image size and the pixels-per-inch count. In my experience the higher definition displays tend to display enlarged text more clearly.

\n\n

Finally, I'll link the following thread about programming font options below:

\n\n

https://stackoverflow.com/questions/4689/recommended-fonts-for-programming

\n\n

You can also find good lists by searching around the internet if that link dies. I recommend one of these because coders usually prefer fonts that have a high level of distinctiveness and differentiation between characters, which minimizes the chance that you will mistake a 1 for an l for a ] and so on. This is, for obvious reasons, also very helpful to the visually impaired. I believe that there are Chrome and Firefox extensions that will try to apply a given font to websites as well, so those might be worth looking into if your dad browses online a lot.

\n\n

If you'd like to provide a list of desired specs and a budget, I'd be happy to look around for some models that would be a good fit. Best of luck!

\nWith SSDs getting cheaper and more mature, I am thinking of getting some for off-site backups. I would store system images and media backups on it, updated weekly-monthly.

Assuming price is not a concern, neither one has much of an advantage over the other for your purposes.

The big advantage hard drives have is still price: a 1TB external hard drive is about $60, while a similar-sized SSD is around $300.

Right now I'm on a Pentium D (one of the higher clocked ones not that it matters) and a quadro fx1700 (modern Intel HD are better) with 4gb ram.

\n\n

So my question is this, the CPU and mobo with a new PSU and 4gb ram would be \u00a3150 roughly (I have a case and hard drive) and the 1050ti would be the same price. Would I get more performance gain by getting everything but the GPU now or by putting the GPU with my Pentium D? Eventually I'll have the i5 paired with the 1050ti but I can't afford it all at once.

\n\n

Thanks

I'd upgrade the CPU and mainboard.

\n\n

If you were doing workstation graphics work, the i5-2500's onboard graphics would be a substantial downgrade from your Quadro. But the same optimizations that make the Quadro a powerful workstation card make it a poor choice for a gaming card -- even though the HD 2000 has fewer compute cores and shares its RAM with the system, it'll be faster for games than the Quadro.

My PC is i5-6600K, Gigabyte G1 GTX1070, 16Gb RAM.

\n\n

At the moment I use two monitors - Dell U2414H for gaming and coding and old Samsung BX2035 for Internet browsing.

\n\n

I want to buy 144Hz monitor for games and right now Im choosing within Asus PG248Q, Asus PG279Q, Dell S2417DG, Dell S2716DG and AOC AGON AG271QG. Of course Asus PG279Q is the best, but I have to buy it from computeruniverse.com due to hight price in my country so this option has its drawbacks.

\n\n

The new monitor should become the main one, and U2414H should be used for Internet surfing.

\n\n

In general, I want to get advice on which monitor is better in the described situation, and also I have a few questions:

\n\n
    \n
  1. Is TN really worse than IPS? I always sit in a lighted room and look at the monitor straight so bleeding is not a problem.
  2. \n
  3. Is 1440p good for 24\"? Will not the text be too small? And if I increase the scale, will there be blurrs due to interpolation?
  4. \n
  5. Is 1440p 144Hz good with GTX1070? And will it be good in the next 2-3 years?
  6. \n
\n\n

Actually I rarely play in competitve FPS, maybe I do not need 144Hz at all? As an example of the games I play: World of Warcraft, Dota 2, Starcraft 2, Civilization 6, Fallout 4, Tomb Rider etc.

\n\n

I will be glad to any advice or links to articles.

\n", "Title": "Choosing monitor for gaming", "Tags": "|graphics-cards|monitors|", "Answer": "

1. YES

\n\n

2. I would recommend 1080p for 24\" simply because you will get way more frames per second, and again more PPI, looks better and in this case 1440p with 24\" is about 121PPI and 1440p with 27\" is about 109PPI so really not much of a difference. Also I think I saw couple of 27\" monitors and 2560x1440 at 27\" is the same pixel density as 1920x1080 at 24\"

\n\n

3. It is and for 90% of upcoming games in next 3 years it will be, but then again don't hold my word, we can't predict future tough I reckon you will be able to play them in medium-high settings(in 3 years)

\n\n

The monitors I would recommend are Dell S2417DG and Asus PG248Q tough I prefer Dell over Asus

TL;DR: The LG 24MP59G-P/LG 24MP59HT-P

\n\n

\u20ac2501 is a pretty massive budget for a monitor of that size and resolution. At this price point, I'd consider decent color (read: IPS) non-negotiable. Since you mentioned gaming and programming (not content creation), I'm guessing perfect color isn't too important though. For that reason, I focused on providing a better gaming experience.

\n\n

With both of these monitors, you get a 75Hz refresh rate with Freesync. IMO, these features make gaming (even relatively casual gaming) much, much better.

\n\n

Beyond that, compared to the Dell monitors you suggested:

\n\n\n\n

Given how much room you have left in your budget, it should be within your budget to get a nice USB hub and set of bookshelf speakers.

Between the G and HT models, the difference appears to be in vendors (BestBuy carries only the HT, the G is carried more universally) and inputs (the HT has 2x HDMI and 1x VGA, the G has 1x DisplayPort, 1x HDMI, and 1x VGA.) I'd recommend the G if you can find it (DisplayPort tends to have fewer issues with Freesync.)

I am to purchase RAM for my newly purchased

\n\n\n\n

I want to max out the memory to 64GB and planned to puchase four

\n\n\n\n

The memory I am interested in is

\n\n\n\n

The question is whether the SAMSUNG memory is compatible with the ASUS motherboard.

\n\n

Samsung's Support > Tools & Utilities > Board Compatibility is not helpful, and strangely does not even list DDR4 memory.

\n\n

The QVL (Qualified Vendor List) for memory from ASUS does not list M391A2K43BB1-CPB.

\n\n

Two other Samsung memories are however listed 16GB DDR4-2400 Non-ECC/UNB and \n8GB DDR4-2133 ECC/UNB CL15; the first not fit for the CPU, and the second will only max out to 32GB.

\n\n

The only two vendors that are on the list with an acceptable memory specification 16GB DDR4-2133 ECC/UNB CL15 are INNODISK and Skhynix. Neither of which are available to me for purchase.

\n\n

I found however that the QVL for memory for the ASUS P10S-M motherboard lists the Samsung M391A2K43BB1-CPB.

\n\n

I noticed that the memory chip for the listed Samsung M391A2K43BB1-CPB is the same memory chip listed for the INNODISK memory chip; Samsung K4A8G085WB-BCPB.

\n\n
\n

There are multiple memory companies on the market, but only a few true memory manufacturing companies. When researching different memory brands, you may run across companies that claim to be memory manufacturers, when they're really just module assemblers. How these companies work is that they purchase pre-manufactured parts (such as DRAM chips and printed circuit board) from true memory manufacturers, and then assemble these components to \u201cmanufacture\u201d a module with their label on it.

\n
\n\n\n\n

If I understand correctly, the listed P10S-M WS/IPM-O INNODB M4CR-AGS1MC0G-BE93 is actually more or less the same memory as Samsung M391A2K43BB1-CPB?

\n\n

Even if they would differ for some reason, I am having a very difficult time to accept that the M391A2K43BB1-CPB -- or really any other memory -- will be incompatible with the motherboard save for some edge cases, such as incorrect manufacturing or assembling.

\n\n

As this is my first build it would be assuring if someone could confirm my conclusion.

The question What exactly is the cause of RAM incompatibility? on superuser provides a good overview of possible causes for incompatibility. The answers to the question provide some interesting reasoning.

\n

https://superuser.com/a/1252224/774206

\n
\n

You might have two RAM sticks with the same part number and one can tolerate a 5% undervoltage and the other can't, and the mobo might put out a low voltage because it's poorly calibrated.\nBut, again, this is very rare now. Sane combinations almost always work.\nBefore DDR2, it was a mess. After DDR2, it was sufficiently standardized.

\n
\n

In the follow up discussion https://chat.stackexchange.com/rooms/65926/discussion-between-david-schwartz-and-ehryk

\n
\n

These days, it's almost always the obvious incompatibilities. That is, if it doesn't work, you can usually figure out why. When you can't, the most likely explanation is that some part is just crappy.

\n

In the old days, weird incompatibilities were not that unusual. But since the DDR2 standard, cases of incompatibility not involving one of the explanations mentioned are fairly rare. Most of those cases are likely to be components that are not quite meeting their specifications.

\n
\n

From another answer https://superuser.com/a/1252995/774206

\n
\n

I built many systems throughout my career and I have not once looked at the supported RAM list before I chose the components. And I have never had any incompatibilities so far. That being said, the list can give guidance to beginners and less experienced people to select the correct components to build a good working system.

\n
\n

From another answer https://superuser.com/a/1252617/774206

\n
\n

The answer lies within the memory controller. The memory controller used to be on the north-bridge of the motherboard. It had to negotiate all the features that the CPU supported for direct memory access. So the CPU is really the determining factor that limited what memory you could use even though it appeared to be a motherboard capability. This is more obvious now that the memory controller lives inside the CPU in all modern chips made by Intel, AMD, and ARM. The motherboard firmware contains microcode from the CPU manufacturer that dictates what kind of features for direct memory access it supports. So the software still lives in the motherboard but the hardware is in the CPU now.

\n

The clocking of CPU and Memory are directly linked through the Base Clock. They have to be multiples of each other in sync. Aside from that the details of Direct Memory Access are non-trivial and I will not attempt to explain here. My understanding is that just like MB and CPU manufacturers have different implementations and features, so do different memory modules. Within one memory manufacturer, like Kingston, the actual chips could be made by Samsung, Hynix, or someone else. They should all follow a spec but maybe they don't implement every feature the same way.

\n
\n

While no answer was accepted, one was given the "bounty"; https://superuser.com/a/1252970/774206. The answer provides some examples of what may cause incompatibility.

\n

Using the

\n\n

I have tried to create a comparison table. Mainly for the fun of it :)

\n

My best [uninformed] guess is that with the new CPUs, motherboards and memories the main criteria for memory compatibility is the common referred specifications, and any incompatibility issue is mainly due to "bad luck".

Assuming you want an internal SSD,

\n\n

I would say that you would in theory want an SSD with SLC, however, they are more expensive.

\n\n

For example a search on newegg.com for SLC in the range $100-200 resulted in 1 match

\n\n\n\n

In practice, given your intended use, a MLC based SSD should suffice. A search for MLC in the same range resulted in numerous products. The linked Wikipedia article even states that

\n\n
\n

In February 2016, a study was published that showed little difference in practice between the reliability of SLC and MLC.

\n\n

(referencing Bianca Schroeder and Arif Merchant (February 22, 2016). \"Flash Reliability in Production: The Expected and the Unexpected\". Conference on File and Storage Technologies. Usenix. Retrieved November 3, 2016.)

\n\n

You also need to ensure that the SSD you purchase support

\n\n
\n

... the ATA_TRIM command for sustained long-term performance and wear-leveling.

\n
\n\n\n\n

The only thing that I am aware of when using SSD with Linux is to ensure that the file system you use for the SSD supports TRIM. See the referenced archlinux link on SSD.

\n\n

Given your intended use I would say any SSD with SATA revision 3.0 (\"SATA 3\" or \"SATA III\") interface should perform well enough.

\n\n
\n

You could say the maximum for SATA revision 3.0 is 6Gb/s, and that the maximum for SATA revision 3.2 is 16Gb/s.

\n
\n\n\n\n

I personally run an external SSD with USB 3.0 (can transfer data at up to 5 Gbit/s that is 625 MB/s according to Wikipedia) from where amongst other things I run virtual machines (Windows 7, Linux). For your stated uses I doubt you will have any performance issues.

\n\n

If you want to narrow down your search (MLC) in an effort to improve performance then I would recommend considering an SSD with NVMe interface if your motherboard supports it. The same search on newegg adding \"PCI-Express 3.0 x4\" narrows the search down to about 20.

\n\n

I recommend searching for reviews or comparison videos for more specific examples. My favorite is NVMe SSD Review - Which Should You Buy? - 2017 Edition. Notice what he says in the beginning of the review; NVMe is for high-end machines; for mid-range computer see his \"SATA SSD\" review.

\n\n

Good luck!

Reading Digital Boffon's comment I remembered that I forgot to mention something about read-write operations -- which would have basically been the same tl;dr as the answer Boffon referenced

I recommend a HP printer, specifically the HP LaserJet Pro M130nw. Amazon claims to sell it for $99 once you add to cart.

\n\n

HP has always had the best support on Linux [1][2][3], and the current open source drivers – which are in the default Ubuntu repository (main),* and may even be installed by default^ – claim full support for the M130 series [4]. Linux is also listed as a compatible OS on the specs page

\n\n

It has 802.11 b/g/n as well as 100Base-T Ethernet (and USB 2.0,of course). Print output is 600 dpi maximum, with \"FastRes\" pixel doubling. Scanning is 600 dpi Colour, 1200 dpi Mono. Unfortunately, there is no autofeeder for the scanner. If you want one, you'll have to pony up for the next higher model. Auto duplex, single pass scanning and colour printing are all at far higher price points

\n\n

Recommended page volume is 150 to 1500 pre month for both Print and Scan, though maximum duty cycle is 10 000 pages per month.

\n\n

Its minimum dimensions are 398 \u00d7 288 \u00d7 231 mm, minimum being when all trays are closed, etc.

\n\n
\n\n

*\"main\" means a Canonical maintained package. It likely has the best support.

\n\n

^if it isn't, just sudo apt install hplip in a terminal or search for it in Synaptic or Software Centre. apt has a nice progress bar.

You can go for either matte surface or anti-glare ones.

The rough matte surface panels are still mostly used in the business notebook segment. The other type of anti-glare computer screens, which uses a chemical coating over a smooth surface to cut down glare, is more used on glare panels to minimize the amount of glare there.

If you're looking for a reason to pick one over the other, the EVGA card is clocked 0.7% faster than the Gigabyte.

It sounds like the best drive for your circumstances is a 3TB Western Digital Green.

Normally, I'd never recommend a WD Green because of severe performance issues (the firmware prioritizes power savings over speed of access). However, since you're using the drive for backups rather than as your main drive, the delays probably won't be an issue. Reliability-wise, the WD Green uses the same hardware as the rest of Western Digital's drives. It's only the firmware that differs.

I'm out of space on my Mac so I've been planning to buy an SSD and install some programs there. I know that USB 2.0 has a low bandwidth so there is no point to use SSD through USB 2.0. The question is how do I connect an external SSD drive to my MacBook Pro 2014 that doesn't have Thunderbolt 3 jacks, hence I can't connect USB 3 cord to it. There are some adapters from USB 3 to Thunderbolt 2 that apparently cost about $100-150 so I would avoid buying them if possible.

Thanks in advance!

\n", "Title": "How to connect external SSD to Mac so it doesn't lose speed?", "Tags": "|usb|pc|ssd|flash-drive|", "Answer": "

TL;DR: Don't. Get an SD card.

\n\n

Let's start by taking a tour of your MacBook's I/O:

\n\n

\"enter

\n\n

For sake of simplicity and feasibility, we'll explore three options here: USB, Thunderbolt, and SD.

\n\n

USB

\n\n

Contrary to your original question, you do have USB 3.0! We won't go into it much, but the newer port you're referring to is USB 3.1 Type C.

\n\n

USB 3.0 has a maximum speed of 5 Gb/s\u2013below SATA 3's 6 GB/s, but still above most (even fairly fast) SSDs. All good then, right?

\n\n

Unfortunately, through a combination of packet problems, controller issues (either on the computer or enclosure end), and general magic, USB 3.0 just... isn't that fast. I'm not particularly well equipped to say why, and I wouldn't be surprised if more in-depth analysis revealed flawed testing methodology, but that's the fact of the matter... for now. Still, 3.360 Gb/s isn't anything to scoff at, nor is it too far from advertised.

\n\n

Thunderbolt 2

\n\n

Thunderbolt is kinda the big daddy of external expansion. It advertises 20 Gb/s over a 4x PCI-e 2.0 connection. And for the most part, it delivers... 11 Gb/s. Akito specifically cites the chipset (rather than the protocol) as the limiting factor. Still, that's enough to handle the fastest SATA SSDs, and even decent PCI-e drives.

\n\n

SD[XC]

\n\n

The SD spec promises speed up to 2500 Mb/s for UHS-II. You won't get that on a MacBook Pro, since the reader is connected over a USB bus\u2013in your case, USB 3.

\n\n

One thing to note is that the maximum file size you can put on an SD card varies. Normal SD cards support 2GB (avoid!), SDHC cards support 32GB, and SDXC cards support 2TB.

\n\n

Choosing your connection

\n\n

With this in mind, we get the following:

\n\n\n\n

Note that USB and Thunderbolt are fundamentally incompatible specifications; you cannot convert Thunderbolt to USB.

\n\n

Given that you're using this for secondary storage on a computer with an already very fast SSD and (based on the fact that you said $100-150 was too expensive) price is important, SD cards seem like the way to go. You can even get ones that lie flush with the rest of your laptop, or microSD adapters that allow you to bring your own SD card.

\n\n

\"enter

\n\n

Since you haven't provided a specific price or storage requirement, I can't get more specific than that.

\n\n

If you have no regard for money or physical space considerations, the Sony 128GB SF-G Series UHS-II is among the best I know of, and comes with a 5 year warranty and data recovery to boot, though I would advise against this. I would recommend something along the lines of the SanDisk 128GB Extreme UHS-I and one of those microSD flush-fitting adapters from earlier.

\n\n

The exception to this is if you want a large amount of storage (256GB+ mostly.) SD cards at this price point are still much more expensive than their desktop counterparts while offering worse performance, though this breaking point will likely change in the future as SSD prices continue to drop.

RAID 5 can handle 1 bad drive and 6 can handle 2.

\n\n

Reading will not be significantly impacted by software RAID 5 or 6. However, writing will take a big hit in terms of CPU utilization will spike every time you write to it. If your CPU isn't fast enough your write speed will be limited. You will also have less CPU to run your normal programs.

I'm looking at raw memory speed in a setup where RAM bandwidth is important. Right now the servers are using Xeon E5 16xx v3's and v4's with about 96 - 160 GB of ECC RDIMM 2133/2400.

\n\n

A lot of people ask online about the difference between ECC and Registered RAM, and get told they are completely separate things - I understand the difference and know which RAM I'm asking about :)

\n\n

In this case, unbuffered ECC (UDIMMs) may be better than registered ECC (RDIMMs/LRDIMMs), because I don't need registration or buffering really, the amounts of RAM aren't large enough to justify it, and the speed will benefit from avoiding it.

I'd recommend an Ivy Bridge or Sandy Bridge E3 Xeon, such as the E3 1245. These CPUs are more or less lower clocked i7 chips, and have excellent performance. They will, on average, have a performance between a stock i5 and i7. As shown in these benchmarks, this means that at 1080p, you will easily lock 60 FPS for the latter two games. It is very likely you will be able to achieve a minimum of 60 FPS for the near future (ignoring GPU), except on very CPU heavy games like Assasin's Creed.

\n

As to which Xeon to pick specifically, obviously, the bigger the number, the better. Note that the 1220 and 1225 series do not feature hyperthreading, and you may as well buy the equivalent i5. If you can find an equivalent i7 at under your budget, that would also be an option. Ivy Bridge (v2 or 3xxx) CPUs are more or less equivalent to a Sandy Bridge CPU clocked ~ 100 - 200 MHz faster.

\n

These CPUs require a LGA 1155 motherboard. Check the manufacturer's webpage for compatibility if purchasing a Ivy Bridge CPU.

\n

Honourable mentions

\n

Newer platform, similar performance: The Ryzen 3 1200 is just under your budget for $99.99 at Amazon.com. At stock, it's about the same performance as a higher end IB Xeon but you do get access to some modern bells and whistles on the newer platform. It has an average overclock of 3.9 GHz, which may give a decent boost to performance. On the other hand, the newer platform has higher costs associated with the RAM and others. The Ryzen CPUs use a AM4 socket.

\n

The new Coffee Lake i3s are just out of your price range, but may also be worth considering. The old AMD FX series on the other hand, while a decent amount cheaper, $75 for a "6 core" and $90 for 8 \u2013 and have attractive looking clock speeds \u2013 are definitely to be avoided, as they have significantly lower performance due to low IPC.

Background

\n\n

There are numerous problems with the Intel Management Engine and the AMD Platform Security Processor or similar always-on master key \"backdoors\". Both practical, and (most importantly) ideological.

\n\n

According to my extensive research Wikipedia, all Intel CPUs since 2008 and all AMD CPUs since 2013 have this embedded. Fortunately I don't often upgrade my computer and to my knowledge, my current Intel Core2 Q9400 CPU is not affected. I use Linux exclusively, and use it for electronics CAD and embedded software development.

\n\n

However, my CPU is starting to feel a bit sluggish, especially when building larger projects from source, and I'm now looking for a replacement. Problem is, it's not easy to find, or maybe I just don't know what to look for?

\n\n

In short: I'm looking for a CPU to use in my home desktop machine, to run Linux and software development. This means that it's OK if if has a lot of cores because my workload is easy to parallelize.

A POWER9-based computer

\n\n

If having an x86-64 architecture is really optional instead of a requirement, there are now desktop motherboards designed around the POWER9 CPU by IBM. I have no affiliation with this company and no experience with the platform but here is an example of a \u00b5ATX-based motherboard with a single 8-core (32 thread) CPU and consumer-grade expansions like SATA and PCIe.

\n\n

The only thing not on the checklist is that it lacks two out of six SATA ports - there are only four. Otherwise there's ECC RAM, AES acceleration, etc.

\n\n

Performance

\n\n

The POWER9 CPU is used by the two fastest super computers in the world as of november 2018 so it's definitely a powerhorse comparable to the fastest server offerings by Intel and AMD.

\n\n

Compiler optimizations for the POWER9 is not yet on the same level as the \"ultra-tweaked\" x86-64 clang/gcc, and certain number-crunching applications currently hand optimized for the x86-64 SSE may still not be as fast but it seems that IBM has people working on this.

Software/OS support

\n\n

As far as I know this is not an option if you want to run Windows, but Linux and FreeBSD supports it, and my OS of choice Debian supports it.

I have a Dell Inspiron 7720 laptop for a few years and I would like to buy an SSD disk for it. Currently, I have an SSD disk used as a cache for HDD disk (using Intel Rapid Storage). I want to remove the current SSD disk, use the new one as a system boot disk and the HDD as a data disk.

Since I stopped following new hardware a few years back, I'm not sure what to buy. I don't want you to suggest any particular model, rather just what technology and interface to choose.

mSATA is a standard used to map SATA signals onto a PCI-E mini card connector, in order to run hard drives from a PCI-E connection.

Just a different form factor. It can still only use SATA data transfer protocol, so your throughput limitations are the same between form factors. The big difference from my understanding is where you plug it in.

\n\n
\n

I don't need SSD faster than motherboard's bus can transfer

\n
\n\n

This won't be an issue for you, your bottleneck for data transfer bandwidth doesn't occur here. Since you can't take advantage of the higher-speed PCI-E slot to connect your system boot drive (no M.2 support), you're going to be throttled by the SATA connection limitations anyhow. Don't worry, you'll still get plenty of speed improvement in real-world use.

Samsung has been at the top of the SSD market for a few years. The 850 Pro is about as good as it gets for a 2.5 inch SATA 3.0 drive. I use one in my build and it works great.

If you're shopping around, offerings from Crucial and Kingston can offer competitive real world performance for most workloads at a moderately lower price point.

I am trying to find something that is exceptionally weird and bizarre. I want to use a M.2 NVMe x4 SSD in a PCI-Express x1 slot.

\n\n

x4 NVMe SSDs directly use PCIe bus protocol, and so can be directly plugged into a full-size PCIe slot using a simple passive adapter. But there are four data lines, so these passive adapters are virtually all x4 lane cards.

\n\n

By specification, all PCIe cards are backwards compatible with the lowest bandwidth x1 lane slots. If the x1 slot is designed with an open end, it is possible to plug a x16 card into it with 15 lanes hanging exposed in midair and unconnected, and it will work. It won't work well but it will work.

\n\n

So, what I need is a NVMe x4 passive adapter card, which will plug the M.2 into a normal PCIe x1 slot, and leaves the remaining 3 lanes unconnected.

It's amazing how much things have moved on since the OP. PCIe is so versatile. NVMe SSDs are just PCIe devices, which are generally backwards compatible with older PCIe versions or reduced PCIe lanes.

(Similar items are available from Amazon if you don't want to wait for shipping from China).

\n

Bandwidth is constrained as expected, but still about twice as fast as a SATA SSD:

\n

The x4 adapters also work fine and avoid the bandwidth constraints (when in a x4 or above slot). In fact I've even successfully used a x4 adapter advertised as PCIe 3.0 to run a Gen 4 drive at full speed in a PCIe 4.0 slot:

\n

\"WD

\n

This allows otherwise impossible things like running two PCIe 4.0 x4 SSDs at full speed on a B550m motherboard (moving the GPU into a PCIe 3.0 chipset slot). Windows can even RAID them, not that you'd want to: \"2

\n

These are passive adapters so will work even on much older motherboards that don't have native M.2 slots (although you probably won't be able to boot from them, unless you are expert at patching BIOSes). For example, I've successfully run a PCIe 3.0 x4 NVMe in a PCIe 2.0 x4 slot

\n

(Even older laptops with PCIe NGFF slots can in theory host other PCIe devices e.g. an M.2 NVMe SSD with a suitable keying adapter, or even an eGPU. Typically this would require sacrificing the internal wifi card in favour of USB wifi).

\n

Beware PCIe adapters that take multiple M.2 drives. They seem to fall into three categories:

\n
    \n
  1. x4 card with one NVMe slot and one SATA slot (the latter usually a passthrough from a motherboard SATA port - as pictured in another answer)
  2. \n
  3. x4 or x8 card with 2 or 4 NVMe slots, but multiplexing the NVMe traffic through a PCIe switch (reducing your theoretical maximum bandwidth, problematic if you wanted to RAID the cards)
  4. \n
  5. x16 card with 4 true NVMe x4 slots, but relying on PCIe bifurcation support in the chipset and BIOS (usually only available on higher-end boards - although if the chipset supports, it may be possible to patch it into the BIOS).

I'm considering a 4k monitor with 120Hz support that uses two DP1.2 connectors; they each render half the screen at 120hz, it's effectively two monitors glued together.

\n\n

Question

\n\n

For gaming, would I see a performance benefit from using a dedicated GPU for each half of the screen? I'm not sure how this'd work under DX11 or 12.

\n\n

Thanks!

\n", "Title": "Dual GPUs for dual monitors, benefits?", "Tags": "|graphics-cards|multiple-monitors|", "Answer": "

Probably none.

\n\n

You're most likely using MST - in a very unusual fashion, similar to how 5k monitors, and the old IBM T220 did. Your graphics card likely is aware that its \"one monitor with very high refresh rates, and I need to render it as seperate tiles\", and I somehow suspect its rendering as 4x1080px120hz 'tiles'

\n\n

I'm unaware of MST even working on multiple video cards.

\n\n

In practice, 4k60 gaming on a single video card is tough - so you'd want to take advantage of SLI/Crossfire or the DX12 multigpu options anyway, which still don't need you to plug in the monitor into different cards.

\n\n

So for regular use, I'm doubtful multiple cards are better than one card capable of presumably handling 2 or more 4k60 monitors. For gaming, you will likely need a eyewateringly powerful setup.

\n", "Title": "What is PSU that I need?", "Tags": "|desktop|", "Answer": "

If you are building a PC, choosing a PSU is quite simple.

\n\n

Most people do not give importance to find the right PSU. But, I personally consider PSU to be a very vital part of a computer. I myself build my first PC recently and I will share with you how I chose the right PSU.

\n\n
    \n
  1. Wattage:\nThe parts that you included has their own power(wattage) requirement. There are other parts of a computer that might require the power from the PSU. So, you got to make of list of all the items in your build - Processor, CPU cooler, Memory, GPU, Case fans, HDD/SDD and any other part that does not have a separate power source. To make the wattage calculation easier, I would suggest that you use this free tool.

    \n\n

    I would also recommend that you consider about the possibility of adding newer parts and/or upgrading certain items.

    \n\n

    My build required around 300 watts of power. However, I chose a 500 watts PSU. This is because, I might include few parts in future and my power requirement might go up to 400 watts.

  2. \n
  3. Modular:\nThis is another major filter. Check this link to know the basic difference between non-modular, semi-modular and fully modular PSUs.

    \n\n

    Non-modular PSUs are cheap but all the cables pre installed(which you cannot remove). Choosing this means you need to work harder on cable management so as to keep good ventilation to your case. If you have a case with a lot of free space, you can go for it. Research about your case to know better.

    \n\n

    Then comes semi-modular and fully modular PSUs with limited cables and no cables pre-attached to them. Fully modular is the highest priced.

    \n\n

    I had the NZXT S340 elite case. This has lot of space for cable management. So, I chose a non-modular PSU.

  4. \n
  5. Efficiency:\nPSUs are rated like any other devices. 80 Plus certified PSUs are energy efficient than the ones that are non certified.

  6. \n
\n\n

\"enter\nThis table will help you with the basic difference between the 80 Plus PSUs.

\n\n
Some brand try to mislead the consumers by not mentioning the correct 80 Plus details. I would not recommend going for a 80 Plus PSU with no medal attached to it. \n\nI chose a 80 Plus Bronze as it was under my budget and because it suited my limited hours of PC usage. \n
\n\n
    \n
  1. Form Factor:\nThis depends on your case. If you case supports ATX form factor, choose a ATX PSU and similarly for other form factors. Research about your case to find the right form factor.

    \n\n

    I used PC Part Picker to check for the compatibility of the various parts of my build.

  2. \n
\n\n

One last thing, I highly recommend choosing a PSU that is meant to be sold in your country/region. This is to avoid any issues with the regulations posed for electric/electronic items.

\n\n

Though I am not an expert, I think I have covered the basics here. Feel free to correct me if I am wrong and/or lacking information.

My Gigabyte GA-B85M motherboard has gone bad. Looking for a better alternative (if possible, around $70).

\n\n

Looking for a motherboard that supports Intel i5 4440 LGA 1150 and daily task involves software development.

\n\n

My existing system has following config:

\n\n\n\n

Need max 6 USB ports

\n\n

No plan for expansions in the future

\n\n

I prefer a motherboard with a good price-to-performance ratio which gives a performance boost for software development, but any descent motherboard will work.

\n", "Title": "Motherboard for Intel i5 4440 LGA 1150", "Tags": "|motherboard|", "Answer": "

TL;DR: A used board that supports VT-d if you can find one and are willing to buy used. If not, whatever board is cheapest here and meets your I/O requirements (currently an ASRock H81M-HDS R2.0 looks like the best option.)

\n\n

I'm assuming you've checked and your board is out of warranty and that RMAing it isn't an option. If not, I'd recommend you go that route (though from anecdotal experience, Gigabyte is particularly poor with RMAs.)

\n\n

First, let's take a look at the various chipsets for the LGA 1150 socket.

\n\n

\"enter

\n\n

You'll notice that as we go down the list, the boards essentially get better.

\n\n

Straight away, we can ignore some things: since you've got a Haswell CPU with no plans to upgrade, we don't care about having a _97 series board for compatibility purposes. Again, since you have no M.2 devices with no plans to upgrade, we can ignore the _97 series on that front.

\n\n

Since your CPU doesn't support overclocking, and you have no plans to upgrade, getting a Z series board is unnecessary for overclocking. As such, no motherboard will offer a performance boost, assuming it supports your RAM speed, which\u2013based on the tier of the rest of the system\u2013I'm assuming isn't particularly high, and is likely supported by all motherboards.

\n\n

After that, the main difference is mostly I/O. Your requirements are quite low, and any board at all will fit these requirements (at least 2 SATA 3 ports and one RAM slot.) You mentioned \"max 6 USB ports\", but didn't clarify if you needed USB 3 on those ports, nor how many were provided by the case. I'll assume for now that 2 USB 3 ports, 4 USB 2 ports, and one USB 2 header is enough, which puts almost any motherboard on the list. I'm also going to assume you want an HDMI port on the motherboard, and that you'd prefer not to get a (relatively inexpensive) passive DVI to HDMI adapter. You also mentioned wireless keyboard/mouse, but since your current board doesn't have built-in Bluetooth, I'll assume you already have some solution.

\n\n

However, your CPU does support one interesting technology: VT-d. Basically, it allows you to directly pass through I/O devices (like GPUs) to virtual machines with no* performance degradation. Though it's not for everyone, as a developer, this can be quite useful. Though Wikipedia lists only Q87 boards as supporting VT-d, this is incorrect. For example, the ASRock H87M Pro4 supports VT-d, as does the B85 Pro4. However, so far, I've been unable to find an H81 board that supports VT-d.

\n\n

LGA 1150 boards are new enough that there's enough stock lying around that getting a new board won't cost you too much extra while providing you with a warranty and other nice benefits... if you're willing to use a Micro ATX H81 board. This prevents you from using VT-d, and will limit both your I/O and expansion options. Buying other boards new is significantly more costly, with the cheapest not-H81 board currently being a ECS B85H3-M at $63.32 (though it appears to lack VT-d, defeating the main point of getting such a board), followed by the Biostar TB85 (again, also apparently lacking VT-d), and the Asus B85M-G R2.0 at $96.59, well above what the used market is at (roughly $40), while having poor to mediocre I/O selection.

\n\n

Of course, buying used comes with its downsides. If you want the best value, it will also take some searching\u2013Craigslist and eBay auctions can be a significant hassle (I couldn't find any eBay Buy It Now offers that fit your requirements and were decent value.) If you're not comfortable with that, I'd suggest saving the money and just getting a cheap H81 board, unless you have an immediate use case for VT-d. Those used boards will still be around.

\n\n

As always, make sure your case will fit the board too!

I have an application where I need to write a lot of data continuously (several GB/day). It needs to fit in a very small package. It will be deployed in very remote places.

So my daily driver of 3 years, the Lenovo G50-70, is on it's last legs, and I am in the market for a new high-end laptop to replace the G50-70.

\n\n

I have found these two laptops that fit rather nicely in the my budget of $2000. The problem I face is that I cannot decide which one to choose over the other!

\n\n

Here is the first Laptop --> Asus G701

\n\n

Here is the second Laptop --> Asus GL702VS

\n\n

Here are the specs of the G701

\n\n\n\n

And here are the specs of the GL702VS

\n\n\n\n

The deciding factor for me here is price to performance. On one hand the G701 has 32GB DDR4 RAM pre-installed, with a 512GB SSD included, but sports the 980m 8GB. Where as the GL702VS sports a GTX 1070 8GB, but only has 16GB DDR4 RAM.

\n\n

What puts me off from the GL702VS is the price of the laptop alone, this doesn't allow me to buy extra addons for it later on, like say a 1TB SSD. So I am leaning towards the G701, mainly due to the fact that I will be able to buy upgrades for it at the same as purchasing the laptop altogether.

\n\n

I do a lot of 3D rendering for buildings and structures, as I work at a engineering firm, so the GPU is kinda important in that regard, but I also want to game at a moments notice.

\n\n

Which laptop should I get? The G701 with the older GPU but better spec? or the GL702VS with the better GPU, but lower spec? If not either? Can you recommend me a better spec laptop with a good GPU in it, but at a better price?

I'm looking for a way to connect to the internet through 4G/LTE and have the ability to secure my own traffic, browse primarily text-based sites (read: I don't need serious media streaming capability), while having the portability of a tablet.

The main hurdle I've run into is I just don't know what's out there that fits that need, because I've always stuck strictly with a phone on a data package, or a PC on a LAN, so I'm not familiar with everything in between. I know there are (for example) tablets with built-in modems, but I don't know if that's what I should be looking for or if I should get an external modem and hook it up to a cheap tablet/ultra-light laptop.

TL;DR: Your motherboard + an LSI 9211-8i, or just a motherboard with more SATA ports.

\n\n

\n\n

If you're willing to manage with a slightly lower amount of ports, just get a motherboard with a bunch of SATA ports! The most I know of is 22 on the ASRock Z87 Extreme11/ac.

\n\n

You'll notice two things though:

\n\n
    \n
  1. You can't find this board. Seriously, good luck.
  2. \n
  3. The specifications say \"22 x SATA3 (16 x SAS3 12.0 Gb/s + 6 x SATA3 6.0 Gb/s) from LSI SAS 3008 Controller+ 3X24R Expander\"

Intel only supports up to 6 SATA-III ports on the various LGA 1150 and LGA 1151 chipsets, 10 on X99 and 8 (???) on X299 (though the MSI X299 XPOWER GAMING AC supports 10.) AMD supports 6 on X370 and X399 apparently caps out at 8. Basically, that ASRock motherboard just has another third party SATA controller built in. That's no fun!

\n\n

This leads us to the section option:

\n\n

Add another SATA controller

\n\n

@cybernard has the right idea, but I'm going to disagree with his hardware choice.

\n\n

Though it's not 100% clear, it seems implied by your post that you don't need hardware RAID support, at least at a controller level. Basically, we just want to present the system with just a bunch of disks (JBOD.) This is going to allow us to save a massive amount of money compared using dedicated hardware RAID card on a card like the Adaptec RAID 71685 (retails for $1120!) which would need to have every drive connected to it (if we used the hardware RAID), since we can continue to use the onboard SATA ports.

\n\n

To accomplish this, we're going to use a much, much cheaper HBA: the LSI 9211-8i (also known as the IBM M1015, or the compatible Dell Perc H200/H310.)

It's popular, cheap (roughly $40), and\u2013with a little work\u2013supports JBOD. Here's a quick guide on how to set it up.

There's a wealth other cards as well, like the monstrous 40-Channel SATA 6Gbps HighPoint Rocket 750, but they're far, far more expensive, and probably overkill for your needs. Remember, you can use multiple cards, and as long as you're not bottlenecking, port multiplication is fine. Internal SATA III 1 to 5 cards can be had as low as $60; you don't need a fancy backplane (though if you're into fancy cases with fancy hot swap, boy have I got a post for you!)

I am choosing a processor for a new PC for parallel floating point computations in R. My tasks are very like Monte Carlo simulations, so the performance is nearly proportional to the number of cores at a fixed frequency. I am not going to overclock the processor. I am choosing between Ryzen 1700 and Core i5-8600k or something of a similar price. What would be the best choice?

TL;DR: The Ryzen 1700.

\n\n

Since you stated server and used gear is out of the question, have no interest in the extra difficulty incurred by programming for GPUs/add in cards like Knight's Landing, and AVX-512 is currently limited to the expensive Skylake-X platform, it's basically a straight comparison of multithreaded performance at that price point.

\n\n

Looking at a list of processors near this price point, the Ryzen 1700X and 1700 come out on top in core count. The only other 8 core is the Xeon E5-2609 V4 which runs at a measly 1.7GHz on the older X99 platform. Intel's similar hexacores at this price point are the i7-6850K and i5-8600k.

*A note on the Geekbench FP scores: since Geekbench doesn't provide averages for FP scores, I selected a given run with the closest-to-average run on the first page of search results run on a computer with a valid identity on an aftermarket motherboard at stock frequencies. Ryzen 1700, Ryzen 1700X, i7-6850K, i5-8600k.

\n\n

As shown by these benchmarks, there's a bit of a smattering of who's on top. Geekbench leans towards Intel's single threaded performance being king, while Userbenchmark leans towards Ryzen's cores. Without a benchmark using your workload, it's impossible to tell exactly how things will bench, but I'm inclined to lean towards more cores with a slower individual clock for your workload.

\n\n

Since none of these platforms use DDR3, there's no real advantage towards shifting towards one platform based on memory. Though there may be a slight platform cost incurred by the need for faster memory with Zen processors (especially with RAM prices so high right now), this is relatively small and outweighed heavily by the cheaper motherboard cost\u2013A320 is a perfectly valid option since you're not overclocking\u2013though you may find that a slightly more expensive B350 board provides some nice creature comforts for just a few bucks.

Recently I using Quad Core Q8400 with Asus P5g41t - mlx within FSP Aurum 650 Watt 80 Gold plus. OS Windows 10.

\n\n

I've planning to upgrade my processor to xeon X5470. I used my desktop to design graphic.

\n\n

According to this site said Q8400 is the winner. In fact, from the technical specification they are different. I thought X5470 should be the winner.

\n\n

From ark intel site, Q8400 have specification like this bellow :

\n\n

However why CPUBoss said the Q8400 is winner? Which one the best? if its worth it to upgrade to xeon x5470? Why the price of Q8400 is still expensive if we got the better performance on cheap price? Let say core 2 extreme QX9650 is still more expensive than xeon X5470.

\n\n

\n\n\n\n

I am a bit confused because the i7 and the ASRock motherboard both specify DDR4 2400 RAM.

\n\n

Looking at other questions I found a link to the Crucial memory and one of the suggested alternatives is Ballistix Tactical 4GB DDR4-2666 UDIMM.

\n\n

Is the speed, such as DDR4 2400 just a suggestion and faster can be used or what?

\n", "Title": "Can I use DDR4 3000 rather than DDR4 2400 with ASRock Z270 Killer and I7-7700K kaby Lake", "Tags": "|motherboard|memory|", "Answer": "

TL;DR: It will run at that speed, and it will be an asset in some workloads.

\n\n

Memory overclocking and XMP

\n\n

Intel specifies that their CPUs (here, the 7700K) are guaranteed to work with DDR4-2133/2400, DDR3L-1333/1600 @ 1.35V. Anything beyond that isn't officially part of their specifications, or guaranteed to work. However, in practice, it will.

\n\n

What's going on here is overclocking\u2013basically, pushing stuff beyond it's manufacturer rated speeds. This practice isn't unsafe, and, in the case of memory, is basically supported by the manufacturer. Here, the RAM manufacturer certifies that the RAM will work at 2666 MHz. Though the motherboard manufacturer only guarantees that RAM at 2133/2400 MHz will work, it supports overclocking up to 3733 MHz and beyond (and effectively guarantees it will work.) Similarly, Intel allows their CPUs to work with overclocked RAM (and effectively guarantees it will work.)

\n\n

Because memory overclocking takes work, Intel created something called XMP, or Extreme Memory Profile. Basically, this is a list of settings stored on the memory modules that tell the motherboard what speeds it says it can overclock to and what timings it needs to do so. Most motherboards will then automatically discover and load those settings, though some may require manual configuration. The end result is the same though: the memory runs at its \"overclocked\" speed.

\n\n

RAM speed as an asset

\n\n

Though I won't dive into it too much, how much\u2013if at all\u2013RAM speed matters depends on your workload. This video does a much better job examining it then I could ever do, but the basic conclusion is that it matters a little in some games (more on Ryzen then other platforms) and varies widely for other workloads. If you're building for gaming, don't sweat it too much; if you're building for some other task, Google around and see what other people have experienced.

CS:GO is a pretty lightweight game, and if you really turn everything down, it can run on just about anything. This guide should allow you to squeeze a little out, and\u2013if you're willing to go a bit farther (though there's been some debate as to if this is VAC safe) this guide should be able to help you get even a potato to run CS:GO.

\n\n

Normally I would post the information you need (at least roughly) here, but there's simply too much content.

\n\n

However, there's only so much you can do, and if you're still unsatified with your performance, I can really only recommend getting a different PC.

\n\n

I'm really not a fan of trashing hardware\u2013anyone who knows me or has read my posts knows I'm a massive fan of upgrading and used hardware. The problem is there's almost nothing that can be done with your PC.

\n\n

Problem 1: Your CPU

\n\n

To put it simply: it's too weak. Sure, it may be a quad core, and sure, it may boost up to 2.64 GHz, but with a 6.5W TDP, it is not a performer. CS:GO is heavily CPU dependent\u2013especially single threaded performance\u2013and this just can't keep up. It scores a mere 600 for a single thread in Passmark, getting thoroughly beaten by the 11-year-old Q6660, which scores a 924 without overclocking.

\n\n

Problem 2: CPU upgrade

\n\n

You can't. Though the spec page doesn't exactly make it clear, looking at some other J3710 equipped motherboards shows they are clearly soldered down.

\n\n

Problem 3: GPU upgrade

\n\n

HP prebuilt consumer towers are notorious for being annoying to install new GPUs into\u2013however, even ignoring that, I can't recommend a GPU upgrade. There's almost zero information officially from HP as to if this is possible (I couldn't even find a picture of the motherboard), but we can makes some guesses. First, you're hard capped at 90W for your entire system, since as far as I can tell, the PSU is not upgradeable. This, combined with the fact that I wouldn't be surprised if your slot is capped at the lower 25W limit instead of the normal 75W limit as is fairly common among low end prebuilt, means I wouldn't trust anything above a GT 1030 to work. Though weak, the 1030 would still be enough for CS:GO. However, it costs $80\u2013for which price, you can do much better.

\n\n

A \"new\" rig

\n\n

Base platform

\n\n

The key here is used components. We're going to start with a base platform. LGA 775 is old enough that they can be found really, really cheap, but is still good enough to provide an entry level experience. My personal choice is the Optiplex 755 with the Optiplex 780 in second, but any tower with support for a Core 2 Quad should work just fine. You should be able to find one for sale for $5-25; here's an eBay listing for $17.99. Your best bet to maximize value will be to search Craigslist and your local surplus markets (especially since you'll be able to save all that shipping cost); I find universities often have good stock of these older towers.

\n\n

CPU upgrade

\n\n

You'll need to check your platform first, but across the board, Core 2 Quads are very cheap. The Optiplex 755 can take a Q6600 (about $8.50), while the Optiplex 780 can take a Q8300 (about $7.00.) You can also try overclocking a hair to squeeze a little more performance using SetFSB.

\n\n

Memory

\n\n

Find the cheapest 4GB set of DDR2 available at the minimum speed required by your system. Make sure not to buy ECC or FBDIMM RAM, as these are not compatible. Craigslist may again be useful, or it may not. Here's a 2x2GB set for $8.10.

\n\n

PSU upgrade

\n\n

Buying cheap power supplies is never a great experience, but it'll have to do. Because there's so much variability, you'll need search around a bit. Check Craisglist and /r/buildapcsales. Here's a CX450W for $17.99.

\n\n

GPU

\n\n

Again, there's going to be a bit of shopping around here\u2013what you can get will also depend on what PSU you got. The 9800GT for around $13 should do the trick, but I'd recommend the HD 5850 for around $25 if you can spare, or the HD 6950 for around $40 if you'd like to step it up a bit.

\n\n

With a little time and effort, you've put together a decent little gaming PC for $50-100! I guarantee you this will play better than trying to upgrade your old PC for the same cost.

\n\n

From that, I chose the above four cases, primarily based on drives/volume and availability (since some of the cases have unfortunately been discontinued.)

\n\n

Inwin IW-MS04

\n\n

At 13.3 liters with support for 4x3.5\" HDDs hidden behind a pretty face, this case is pretty impressive in itself. What's more, these drives are hot swappable. However, this does come at a cost: though it comes with a 265W Bronze PSU, you probably won't be able to upgrade from this if you decide to, since the case only supports Flex ATX power supplies. The $160 price tag doesn't help either. Oh well. Still worth a look if you meet the power requirements!

\n\n

Fractal Design Node 304

\n\n

At 19.6 liters with support for 6x3.5\" HDDs with support for full ATX PSUs up to 160mm in length, this case sure packs a lot into a little package, and for $100, isn't too expensive either. Fractal Design also has an awesome reputation and good looks.

\n\n

Silverstone DS380

\n\n

Unfortunately @Nicholas Martin got to suggest this before I could, so I'll just have to second the quality of this case. At 21.6 liters with support for 8x3.5\" HDDs in hot swap bays, this is the best in drives/volume. It's not too expensive at $150, but you will need a more expensive SFX or SFX-L PSU. Silverstone also has a solid reputation and good looks.

\n\n

Discontinued cases

\n\n

Sadly, there are several cases which I would have loved to recommend, but are discontinued and out of stock: the Lian-Li PC-Q26, Fractal Design Array R2, Lian-Li PC-Q08, and Rosewill Legacy V6-B. If you can find one of these used, they're amazing options, but my guess is they were discontinued due to low volume sales, as they're fairly specialized products.

\n\n

Not-quite recommended

\n\n

The Inwin BP671 is a cool little case at a mere 8.2L that supports 2x3.5\" drives. However, the bundled 200W TFX PSU is just too weak and too sketchy for my recommendation, and availability of TFX PSUs is quite low.

\n\n

The Silverstone RVZ01B and Silverstone FTZ01 are both neat little cases at only 14L, but 1x3.5\" drive is just too little for NAS purposes.

\n\n

Really small cases

\n\n

If you were paying extra close attention, you'll notice at the bottom of my table I listed three cases that don't even support 3.5\" drives! Okay, yes, I said I wasn't going to do this, but I had to mention them if not recommend them. They're all extremely tiny, extremely well built, extremely expensive cases. Even though they're not really appropriate for this application, they're interesting to look at.

\n\n

Registered DIMMs won't work on Ryzen, plain and simple. Ryzen isn't validated for ECC support on consumer chipsets and, as a result, AMD doesn't officially support it. ECC support is however enabled, and certain motherboard manufactures do validate ECC memory.

\n\n

Here's a list of AM4 ITX boards that have been validated with ECC memory:

Overview

\n\n

I am trying to build a PC for high-res video editing (2K and a bit of 4K with Premiere Pro), audio manipulation, general use, and a touch of gaming. I want it to look cool, but not sacrifice money or performance for looks. I have done some research and found some parts that I might use, but I need advice to continue. I will probably not overclock my PC.

\n\n

Part List

\n\n

I made a part list on PCPartPicker, which is here.

Questions

\n\n
    \n
  1. Would you recommend getting thermal paste like this for the CPU?
  2. \n
  3. Are there any other suggested parts?
  4. \n
  5. Is there a way to keep it as good as it is but make it cheaper? A friend told me I could use a 1070 graphics card instead of a 1080. Would the difference be noticeable?
  6. \n
\n", "Title": "A few questions about my PC build", "Tags": "|graphics-cards|motherboard|pc|processor|", "Answer": "

If you're doing anything super intensive editing wise I'd go for a quadro, but if you're just splicing clips, making wedding vids and the like a 1070/1080 will do you fine. I think you'll benefit more from single core performance in this build. Go for intel.

\n\n

One thing to consider are accessories like the palette gear if you do a lot of editing on a regular basis.

I was having issues with my PC so I cracked the tower open. In the process of my investigation I looked at my eSATA card and noticed on the opposite side of the circuit board from the capacitor it appears to have been some dried up substance. \n\"enter

\n\n

I believe this issue is unrelated to my original problem, but is this something to be concerned with - and does this warrant a new eSATA card?

\n\n

Here it the top, with the capacitor in question. \n\"enter

\n", "Title": "White substance beneath capacitor. Does this require replacement?", "Tags": "|pc|", "Answer": "

That's a leaked capacitor, you could repair it yourself if you are comfortable with that, but hiring a repairman might be more expensie than a new card. Atleast if you're in the usa where labor is more expensive than parts.

\n\n

I'll post some resources for a diy repair tomorrow, it\"s a cheap project to try with a card that isn't going to get any less dead otherwise.

I want to build a PC with my son. Or rather, at some point have it so he gets to build it (I'm thinking of torturing him by re-formatting Linux every so often and having him reinstall it). I'd like to do with it mini-ITX for a number of reasons, one of which is that he could take it over to his mom's on alternate weeks.

\n\n

I have build PCs from scratch before, but a long time ago, on full size desktops. I'm also fairly comfortable with Linux installs.

\n\n

Here are some criteria/considerations for me:

\n\n
    \n
  1. Relatively cheap to start out with, but room to improve or swap components.

  2. \n
  3. based on Linux, so hardware needs to support it. Don't want really spiffy feature set that needs Windows drivers to work. Related to that - a mobo/chipset that doesn't require extreme UEFI mangling before it will boot from a Linux boot USB.

  4. \n
  5. gaming? Light gaming, possibly via Steam and possibly output to a 1080p TV via HDMI (1.3?). I also have big gaming monitor. But first we need to get working.

  6. \n
  7. I'd prefer a motherboard with some basic onboard GPU, but allowing me to add a better discrete GPU later on (that's related to #1 and #3).

  8. \n
  9. Still relatively small, because he should be able to take the box itself, minus peripherals, with him to his mom.

  10. \n
  11. AMD? Even before the recent security mess, I was thinking of them, just because I like them. But I think I saw people being concerned about the quality/cost of AMD Ryzen minit-ITX boards.

  12. \n
  13. High speed support for external HDDs (offline backups) - USB3 or eSata.

  14. \n
  15. low power, relatively silent, even if that clashes a bit with the (light) gaming.

  16. \n
  17. Finally, quality, quality, quality, rather than just features. I'd never recommend ACER over ASUS in laptops for example, that's just my own personal prejudices.

  18. \n
  19. Peripherals. What about a console-style controller or wireless mouse and keyboards, esp if it's being used with the TV. Anything to be careful about?

  20. \n
\n\n

Share some pointers or war stories? I'm not so much asking for detailed parts list as general considerations of what to look out for from people who've done this and the reasoning that would lead you to choose one class of components over another.

\n\n

Edit: budget 400-600$ preferably, not including monitor, keyboard and mouse. To an extent, I'm good with used, and we have some really good donation places - rather get good stuff at core, w cheap secondary stuff that I can swap out later. A cheap used, or new, GPU would be OK too, I can always update it later.

TL;DR: Option 3 (way down at the bottom) with a Node 202

\n\n
\n\n

Because upgradability and the experience with your son seem to be important to you, I'm going to rule laptops, NUCs, and other prebuilt solutions out of hand. To be clear, this isn't to say that a laptop + evideo card or something along those lines would be a particular poor solution in terms of the end product\u2013I might even argue better\u2013but it seems to conflict with your mission.

\n\n

With that in mind, it's time to build a SFF PC!

\n\n

Point-by-point

\n\n
    \n
  1. Your $400-600 budget is plenty to build even a complete machine, so I'll focus on a few options: 1. Kitting out the build with great, new components and a focus on an immediate future upgrade. 2. A solid new platform with money left in the budget to be spent in the future on big upgrades. 3. A \"game-now\" system using used components to maximize performance on a budget.

  2. \n
  3. Linux support is virtually universal these days. I won't be focusing on building a computer that's open from top to bottom (if you want to avoid the IME/TPM check out this post, and read up on Coreboot/Libreboot), as it's both difficult and not really the focus of this question.

  4. \n
  5. Every system here will boot from day 1. Performance will obviously be the best with the 3rd option.

  6. \n
  7. We'll come back to this.

  8. \n
  9. They'll all be small.

  10. \n
  11. We'll come back to this a bit more later\u2013there's plenty of reasons to go either AMD or Intel, and I'll only focus on performance\u2013but Meltdown and Spectre specifically won't be discussed. While numbers are still coming out and nothing is final, Meltdown's hit appears to be fairly minor in gaming\u2013syscalls is where it hits the worst. Spectre is pretty much architecture aignostic (present on both AMD and Intel chips as well as ARM) with no clear fix, so nothing can really be done there.

  12. \n
  13. We'll come back to this more later.

  14. \n
  15. Low power is dependent on what you throw in there, and yes, does slightly clash with light gaming. Quiet is more dependent on form factor. We'll touch on this again more.

  16. \n
  17. Most computer components these days do quite well on quality. The only places we'll really be concerned with this are the case and used components.

  18. \n
  19. Peripherals will be covered separately.

  20. \n
\n\n

Case

\n\n

The thing about a case is that it's ultimately a matter of taste, and I can't decide that for you. With that, I'm going to provide a range of good cases and let you choose what you like.

\n\n

That said, I'm going to recommend the Node 202 on personal preference.

\n\n

Very small cases

\n\n

These cases are generally described as \"artisan\": made by specialized companies in low volumes, with extremely good build quality, at extremely high prices.

\n\n

Dr. Zaber Sentry

\n\n

$235 (TBD), 6.9L, 305mm video card, 5x2.5\", SFX-L PSU

\n\n

\"\"

\n\n

It's the epitome of a very small case: extremely expensive, extremely tiny, extremely good build quality (primaily powder coated steel), pretty good compatibility with a few things to keep in mind, and runs a bit hot, but generally extremely good. One big issue though: you can't buy one. They're apparently targeting Q1 2018, but for now, I can't recommend what you can't buy.

\n\n

NFC Skyreach 4 MINI

\n\n

$199, 5.0L, 215mm video card, 2x2.5\", special

\n\n

It's the smallest case in this category, but with that come some serious compromises. video card compatibility is very limited, drive mounting is limited, and most of all, PSU compatibility is virtually nil, with only two PSUs listed: a $95 400W DC-DC and a $58 200W DC-DC. If you really value space, this is the way to go; but otherwise, I'd stay away.

\n\n

\"\"

\n\n

DAN A4-SFX

\n\n

$255 (TBD), 7.2L, 295mm video card, 3x2.5\", SFX-L

\n\n

\"\"

\n\n

You like shoeboxes? I like shoeboxes! Made under contract by Lian-Li of mostly aluminum, it's (IMO) the prettiest case on this list. But again, it's not for sale yet (just preorders), and I can't recommend what you can't buy.

\n\n

Pretty small cases

\n\n

These cases are a step up in size from the very small cases, and benefits to match. These are largely cheaper, easier to work with, have better support, and are actually available to purchase!

\n\n

NCASE M1

\n\n

$195, 12.6L, 317mm video card, 3x3.5\" + 3x2.5\", ATX (SFX-L highly recommended)\n\"\"

\n\n

The sort of \"daddy\" of small cases, the NCASE M1 is the last artisan case on this list, and one of the older ones here. It has incredible support for hardware (even a slimline optical drive!), while being spacious enough to keep things from getting too toasty.

\n\n

Fractal Design Node 202

\n\n

$80 or $130 with a 450W PSU, 10.2L, 310mm video card, 2x2.5\", SFX-L\n\"\"\nIt's an extremely popular choice, and a good one! Nothing stands out really except for the very reasonable price.

\n\n

Silverstone FTZ01 RVZ01, RVZ02, and RVZ03

\n\n

$85 to $130, 14L, 330mm video card, 1x3.5\" + 2-4x2.5\", SFX-L

\n\n

All very similar with nothing too stand out; the RVZ03 trades the slimline optical slot and 3.5\" mount for an extra 4x2.5\" mount and RGB lighting.

\n\n

\"\"\n\"\"\n\"\"\n\"\"

\n\n

Silverstone ML08

\n\n

$70, 12L, 330mm video card, 2x2.5\", SFX-L

\n\n

\"\"

\n\n

It's literally based on the RVZ02, but smaller, cheaper, less drive mounting, and with an optional handle!

\n\n

Honorable mention

\n\n

The Silverstone SG05 and Silverstone SG06 are neat, but the 250mm video card support kills my recommendation. The Fractal Design Array R2, Lian-Li Q09, Raidmax Element, SilverStone SG07 and SG08, and Xigmatek Eris EN6305 are no longer in production, though they would make perfectly good boxes if you can find them.

\n\n

Not as small cases

\n\n

They're bigger with support for more things! They're also much quieter. Carrying handles are a must here, since you said that regular transport was an integral part to this build. These cases seem to have largely fallen out of favor as smaller cases take over the mITX sector, but I've put them here anyways.

\n\n

BitFenix Prodigy

\n\n

$60, 26.4L, 317mm video card, 5x3.5\", ATX\n\"\"

\n\n

HardwareCanucks put it best: It's a beautiful chassis at a great price with a few minor compromises for that goal.

\n\n

Honorable mentions

\n\n

The Corsair 380T is a great case, but unfortunately, it no longer appears to be in production, and second hand prices for it are absurd. The Silverstone CS01B is also rather neat, but the 190mm max video card length kills any recommendation. The Cougar QBX and Fractal Design Define Nano S are beautiful and compact, but too large to not have a carrying handle and still be intended as portable IMO.

\n\n

Components

\n\n

I'll be leaving out case recommendations from these options; choose whatever you think is best. If you end up needing an SFX PSU, use this list and get whatever wattage you need; if you need an ATX PSU, use this list. CPU cooler is likewise dependent on case selection, but I'll be using the stock cooler as reference, or the Cryorig C7 when not applicable. I'm allocating about $130 to these parts from the rest of these builds.

\n\n

Final thoughts: I would personally go with option #3. Used components are a great way to get value on a budget.

\n\n

AMD vs. Intel

\n\n

To keep things simple, right now, on a $/performance basis, on the middle-high end, AMD wins in heavily multithreaded workloads, and Intel wins in single threaded workloads. Intel also wins in power consumption (though most of that will ultimately come from the GPU.) Given that gaming appears to be your intended use case, I'd recommend Intel. That said, I'm going to provide AMD builds as an option anyways.

\n\n

Looks

\n\n

Because this is likely going to be stuffed in a small case, I didn't bother concerning myself with looks at all. That said, if you do decide this is something important, you can of course tune the parametric filters to have the colors of your choice, and get a heatspreader if the M.2 drive is ugly.

\n\n

Option 1

\n\n

Great, new components and a focus on an immediate future upgrade.

\n\n

Intel List

\n\n

\"\"

\n\n\n\n

AMD List

\n\n

\"\"

\n\n\n\n

Option 2.

\n\n

A new platform with money left in the budget to be spent in the future on big upgrades

\n\n

Intel List

\n\n

Intel unfortunately just doesn't have a CPU in the Coffee Lake lineup at this price point, so no build from them there. I'm not going to recommend last-gen hardware in a build for which upgradability is the main selling point either.

\n\n

AMD List

\n\n

\"\"

\n\n\n\n

Option 3.

\n\n

A \"game-now\" system using used components to maximize performance on a budget.

\n\n

Intel List

\n\n

Okay, there's no neat PCPartPicker list for this, but that's what happens with used components.

\n\n\n\n

Alternatively, if you've having difficulty finding that motherboard...

\n\n\n\n

And if you're still having trouble...

\n\n\n\n

TOTAL: $496-$565

\n\n

The savings aren't as much with mITX systems as full towers, but it's still a good chunk of change for significantly better performance.

\n\n

AMD List

\n\n

AMD's older offerings just simply aren't competitive, and stock is much lower to boot.

\n\n

Peripherals

\n\n

I'm too tired to go into this in too much depth\u2013and I think it might warrant its own question\u2013but the Roccat Sova MK for M/KB, and a PS4/Xbox One controller if you want a controller.

\n\n
\n\n

I think that's about it! I hope this helped, and I'll be happy to answer any questions you have.

I'd like to build a homebrewed tablet-style device that can run an Ubuntu-ish OS pretty well. The easy solution for a DIY computer is the Raspberry Pi, since it has reasonable power and supports myriad customization, but it's too chunky for what I'm planning. Here's my wish-list of requirements:

\n\n
    \n
  1. Thin overall architecture - I'm thinking about 1/2\" thick at most, and less is better
  2. \n
  3. Around 1.2GHz processor or better - I want it to be able to run a light GUI with good responsiveness, not having to constantly wait for input to get recognized
  4. \n
  5. 2GB of RAM would be great, obviously more is better
  6. \n
  7. Micro SD slot for OS (onboard memory for the OS would be fine too, as long as I can expand it with a card)
  8. \n
  9. Ability to attach a simple touchscreen - I can flex on this, if it can run a screen but can't do touch then I'll deal with it
  10. \n
  11. At least one free micro USB port - I'm flexible on power options, as long as it can be charging/powered while having a free port
  12. \n
  13. Built-in wifi (preferably also Bluetooth)
  14. \n
  15. HDMI-out would be a bonus but isn't required
  16. \n
  17. Low-budget is preferred since I'll be building a lot of it myself, but I'm willing to spend a couple hundred if something really fits the bill
  18. \n
\n\n

I'm expecting to have to do a lot of modification myself, and I'll be designing my own case (unless there's a commercial one that suits my needs). Pretty much what I'm hoping for is a slimmer RPi with the same power, just fewer ports. I know there's the Pi Zero W but its significantly reduced power and memory are too constricting. What other options are there?

Thin overall architecture - I'm thinking about 1/2\" thick at most, and less is better

Around 1.2GHz processor or better - I want it to be able to run a light GUI with good responsiveness, not having to constantly wait for input to get recognized

2GB of RAM would be great, obviously more is better

Micro SD slot for OS (onboard memory for the OS would be fine too, as long as I can expand it with a card)

Ability to attach a simple touchscreen - I can flex on this, if it can run a screen but can't do touch then I'll deal with it

At least one free micro USB port - I'm flexible on power options, as long as it can be charging/powered while having a free port

Built-in wifi (preferably also Bluetooth)

Can a laptop with a AMD or Intel CPU, an AMD GPU and a Thunderbolt port connect to an external GPGPU box with a NVidia card?

\n\n

The code to run on the external GPU could be either OpenCL or CUDA based.

\n", "Title": "External NVidia GPGPU on an AMD based laptop?", "Tags": "|graphics-cards|thunderbolt|", "Answer": "

According to this Wikipedia article, the external GPU will be connected by carrying the PCIe bus signals over a Thunderbolt connection, at the speed of upto PCIe x4 rather than x16. Now, for many general-purpose computing applications, the PCIe bandwidth is already a bottleneck at x16 (16 GB/sec theoretical, 12 GB/sec actual), so reducing that by a factor of 4 would be terrible. If, however, you have a lot of computation to do on every piece of data, this should be possible. (I'm not being definitive since I haven't tried this myself).

\n\n

It's likely, however, that the whole exercise is not worth it, and you should just get a small-form-factor PC which fits a full size GPU (here are a few of them, in a roundup from April 2017).

I'll open by saying I am not an authority on VR tech nor do I follow the scene as a hobby. I own an HTC Vive and have used a Rift once or twice.

\n\n
\n

TL;DR: I love my Vive, I'd spend the money above the Rift to get it, but that's not the right choice for everyone. Promising tech is on the horizon. Promising options on both the lower and higher budget ends outside of the Rift and Vive.

Additional Vive Info:

\n\n

HTC recently announced their Vive Pro which introduces a number of feature additions and upgrades:

\n\n\n\n

HMD-only (upgrade your current Vive kit, rumors of a trade-in program) scheduled for Q1 2018 (next 2 months or so) and the full kit scheduled for a Q3 release. Prices not yet confirmed.

\n\n

PIMAX:

\n\n

I'll be honest on this one, I haven't looked terribly hard into it. I try not to get too invested in a product until I see a consumer-ready version and with Pimax they are 100% not ready for consumers. I've heard the bump in resolution (which is certainly not 8k, it is 4k for each eye which is half as many pixels as 8k) is something to behold.

\n\n

I've seen a few Pimax videos and right now it sounds like the consensus is that the 200 FOV is incredible, the resolution is incredible, but the tracking is still far behind its contemporaries, and price is yet to be confirmed. Hopefully someone who follows this story closer can correct me here.

\n\n

I personally won't bother considering the Pimax until it has been in consumer rotation for a little while, but do some research as the tech is pretty impressive. And you can look like a bug person.

\n\n

Windows Mixed Reality (WMR):

\n\n

Another category I don't have much experience with but from what I have read this market segment is very promising. Compared to the Rift and Vive, most of these headsets are very affordable and boast a higher resolution and PPI. I'm not sure how broad the game support is but I know people have played some popular Vive games without much issue at all.

\n\n

One of the biggest pros for the WMR headsets is their \"plug-in-and-go\" style of inside-out tracking. This means that there are no external tracking devices that must be arranged in/around your play area. The limitations of this are that if your controllers are out of view of the tracking cameras on the headset they can still be tracked but only using the accelerometer, i.e. they must keep moving to be tracked. I've heard this causes problems in games that use \"utility belt\" style inventory systems where you otherwise would be able to interact with certain game features more naturally.

TL;DR: The LG 24UD58-B

\n\n

\"enter

\n\n

First, let's figure out what resolution we need to have.

\n\n

Since pretty everything on the market right now falls into either 1080p/1440p/2160p, we can ignore pretty much all other resolutions (at least for considering what we'll need in terms of resolution.)

\n\n

Your 14\" 1080p laptop gets you of 157.35 PPI. Targeting a standard 23.8\" 16:9 monitor, 1440p gets 123.41 PPI and 2160p gets 185.12 PPI. That in mind, you're sort of in a weird middle ground relative to your laptop. I opted to go for a 2160p monitor, but if you're fine with it, a 1440p monitor would be perfectly valid.

\n\n

That alone gets us down to two monitors: the LG 24UD58-B and the Dell P2415Q. The price difference is pretty negligible, so it's down to picking features.

\n\n

(LG review, Dell review)

\n\n\n\n

I'm aware you don't have an AMD GPU, but given the rather negligible difference otherwise, I'm strongly inclined to recommend the LG monitor.

He is a civil and a mechanical engineer, so I would figure he would be designing build support systems, walls and other complex mesh objects.

\n\n

He uses AutoCAD, CAD, Autodesk, TurboCAD, 3DS Maya and Meshmixer in his line of work. With this in mind, I found two laptops that are within his budget of 2200USD on eBay.

Here are the specs of the first one -->

Long story short, which of the two laptops would you recommend for my friend here, and why? If you have a better recommendation than these two laptops that I have listed, please don't hesitate to mention it. I will take all the help I can get!

Definitely the GTX 1080!

I know benchmarks aren't always showing the whole picture but when the benchmarks show 4 times the performance on a card it is obvious which one is better, for any task whatsoever. In Videocard Benchmarks it is a difference between 3376 for the Quadro M2200 and 12185 for the 1080.

While Quadros have some benefits in workstation kind of devices since they are specifically targeted for these kinds of workloads, but not when you compare one of the top latest GTX cards to a mid (if now lower) range and older generation Quadro (you wouldn't even find a lot of \"vs.\" articles online about these two, since the M2200 is compared which much lower-end GTXs.)

Not so important:

Graphics. Preferably not internal Intel graphics. Internal AMD graphics would be fine, but I think you cannot get this with more than 4 cores/8 threads. So the best option is likely relatively low grade discrete mobile graphics from AMD or nVIDIA.

I hope someone has some knowledge about whether it is recommended (and if so, what specifically) to invest in solar panels in order to power a PC of about 1000 watts, that will run 24/7 (to do machine learning).\nIf the setup works, I might wish to add another PC over time (with an extra panel).

\n\n

Living in an apartment (in Europe), the solar panels should be more or less mobile so I can mount them on the balcony.

\n\n

I hope to reduce the burden on the environment as well as on my wallet eventually :)

\n\n

Thanks for any advice!

\n", "Title": "Recommended (mobile) solar panels for PC setup with a power-supply of 800-1000 watt", "Tags": "|power-supply|solar-power|", "Answer": "

A typical solar panel electrical package will include a series of solar panels (rating and quantity based on expected load), a charge controller, a battery bank (rating and quantity based on expected load) and an inverter (yes, rating based on expected load).

\n\n

If you are confident that you will need 1000 watts of power, you should be configuring your system for at least twenty percent more than that, as one does not achieve one hundred percent efficiency from solar panels. If one is in an area of less than ideal weather conditions, one should increase the size proportionally. For the sake of this answer, I'll stick with the 1200 watt value.

\n\n

In the USA, The Home Depot sells a 1200 watt system with 4 panels of 77 inches by 14 inches (1.9m x .35m) which is quite a large array. These panels include micro-inverters, one m-inverter per panel and provide AC voltage directly to the included controller and sub-panel.

\n\n

This is not the type of system you would want if your intention is to run the computer continuously, but is provided as an example of the size of panels and general configuration.

\n\n

A company called Armory Survival(!) sells an 1100 watt system, also with 4 panels of similar size, but has an off-grid configuration that permits battery connection. Very expensive bundles that do not include batteries means additional expense to have continuous (night) electrical power.

\n\n

A frequent discussion in the electric vehicle world is the concept of a motor vehicle powered by solar panels exclusively. It's a different type of portability, but the numbers are equally challenging.

\n\n

I'm not confident that you'll find a system to meet your requirements, especially considering the balcony constraint. Additionally, if your balcony does not point toward geographic south, the efficiency deteriorates for lack of solar energy.

I have a nice headset with a mic and I like using it for gaming and for using my phone. This means when my phone rings and I'm on my computer I have to unplug it from the computer, put on the adapter for the phone (to combine the mic and audio jacks) plug it in the phone and do it in reverse when I'm done. Is there some kind of switch out there that would allow me to put them both in as sources and just turn a dial to change what goes in the headset? How makeable would that be? (I have very basic knowledge in electronics but I do have access to a fab lab)

\n", "Title": "Switch headset source", "Tags": "|headset|", "Answer": "

I have a device connected to my computer which allows me to select between speakers and headphones at the press of a button. I recognize that your request is not quite that configuration, but the circuit involved in this specific device would function in the manner you require if connected \"in reverse.\"

\n\n

A quick search using the Google for \"headphone speaker switch box\" has provided the expected multitude of results, for example:\nSpeaker Headphone switch

\n\n

I would not recommend this linked item, however, as it contains a volume control. There's no way to determine if any polarity protection is built into such a circuit, although it is unlikely.

\n\n

The box I use is only a switch, the electrons flow in either direction with no problem. It has both speaker and headphone jacks and microphone jacks.

\n\n

You would want to cull out any that have active circuits (requiring external power) and possibly any with a volume control (although that might not be a factor) and aim for the switch box configuration that matches your plug and jack arrangement.

\n\n

All computers using 1/8\" mini-plugs will require that the switch have plug connections to the PC. In your description, you'd have to have one that had jacks instead of plugs, which is unlikely. To accomplish such connections, you would either cut the plugs off and replace it with jacks or purchase female to female adapters to jumper those connections.

\n\n

The other locations in the switch would be jacks to accept the expected headphones and speakers, while your intent is to connect the phone circuit and the computer circuit. This would be accomplished with either male to female jumpers or male to male jumpers, both of which are commonly available online.

Another reason the above linked product is unsuitable is that there is no provision for a microphone. Ensure when you search that the product allows for switching both microphone and headset when performing the button press.

Answers up front:

\n
\n

does it support an additional SSD or have I to replace its current HDD with a new SSD?

\n
\n

Yes, you should* be able to install an M.2 SSD alongside your current HDD (see below). You can also replace the current 2.5 inch HDD with a 2.5 inch SSD.

\n
\n

And which form factor should I look for when shopping?

\n
\n

The M.2 SSD and 2.5 inch HDD / SSD / SSHD form factors are compatible with your laptop. I do not recommend SSHD "hybrid" drives, they're extra money for no real world gain.

\n
\n

Explanation and source

\n

Here's a nicely detailed teardown I found:

\n

https://www.laptopmain.com/msi-gp62mvr-6rf-leopard-pro-disassembly-and-ram-hdd-ssd-upgrade-options/

\n

I'm operating under the assumption that you have a "MSI Leopard GP62MVR 6RF" PRO, as I can't find any info on other models.

\n

From the picture in the link, your laptop supports a 2.5 inch standard form factor HDD / SSD as well as an M.2 SSD.

\n

Seems to me that if you took the HDD option, the M.2 slot will be empty. You can pop off the bottom of the laptop and check for yourself. If this is the case, you can definitely order a compatible M.2 SSD and install it fairly easily.

Many thanks in advance.

\n", "Title": "Tilted motherboard (45 degrees) - is it safe for the long term?", "Tags": "|motherboard|case|", "Answer": "

Your question might be more of an engineering line of reasoning, but it's still hardware related.

\n\n

Consider the mounting points for your mainboard. They are \"scattered\" around the board based on standards for case mount placement. They are almost certainly engineered to take stress from the components on the board and transfer that to the stand-offs attached to the case.

\n\n

In that configuration, the forces are more-or-less evenly distributed over the mainboard, perhaps with additional mount holes near high-load areas such as the processor and heat sink assembly.

\n\n

I have assembled a couple computer boards which did not have stand-offs in the case but had mounting holes. This was a flaw or failure in the case engineering but had little effect on the installation.

\n\n

In your case, literally and figuratively, you would want to ensure that every mounting hole was properly secured and supported the board. If your intent is to secure the mainboard only at the edges, I would suggest that is contra-indicated. To secure all of the points, it would be necessary to build \"branches\" from behind the board to secure where possible, or in front of the board, providing support from either side.

\n\n

The best support will be provided by branches that are perpendicular to the mainboard. Those that are not would allow some flex in the structure. If one cannot create a perpendicular-to-the-board branch, one should consider both a vertical and a horizontal branch joined at the mount point.

\n\n

I would not suggest that it is \"wiser\" to avoid such a construction, as the other factors for this design have not been referenced.

\u00a3100 is a pretty tight constraint, so I won't be able to pull into too many bells and whistles into this recommendation. What I managed to get as a baseline along these three tablets is 32 eMMC internal storage and 2 gb of RAM. I've recommended products you could purchase today that should be available to you in the UK. The only differences between these tablets is the CPUs:

\n\n\n\n
\n\n

Cheapest Option: Onda V80 SE Tablet \u00a371.85 @ Newegg

\n\n

\"Onda

\n\n

This tablet features Android 5.1 and based on it's review it features a older Intel Atom Z3735F Quad Core (Release: Apr, 2014). It's benchmarks indicate this it will operate slower than any of the 3 options, meaning it will be the least \"snappy\" when used.

\n\n

Slightly Better Option: Onda V80 Plus \u00a390.60 @ Newegg

\n\n

\"Onda

\n\n

This tablet features Android 5.1 + Windows 10 (I would recommend using the Android OS unless you need the additional features of Windows). It is functionally the same as the previous option, but with 2 OS's and a slightly better processor, \nIntel x5-Z8350 (Release: Jan, 2016) (it's Passmark score suggests it will perform about 26.5% better than the previous option). You might even want to consider uninstalling the Windows operating system for a little more space as it doesn't sound like the extra functionality is worth the performance hit.

\n\n

Budget Stretcher: Teclast P10 \u00a398.99 @ Newegg

\n\n

\"enter

\n\n

The most powerful of the Tablet options and using the newer Android 7.1 OS, this tablet will stretch your budget, however it is marginally more powerful (according to benchmarks). It's cpu (RK 3368-H) Passmark score suggest it will perform about 2.6x better than the Onda Plus option. This option will be the \"snappiest\" and unlike the previous Onda Plus option, won't come with the wasted space of Windows 10. Consider this option if you want the most bang for buck performance wise.

\n\n
\n\n

Keyboard: Wanmingtek Wireless Keyboard and Mouse Combo \u00a316.99 @ Newegg

\n\n

\"Wanmingtek

\n\n

None of the tablets I curated came with keyboards, most likely because of the low end price restriction. It's a cheap blue-tooth keyboard, weighs less than 300 grams and will get the job done. It also comes with a mouse if you don't feel like touching your screen. This will unfortunately put, option 2/3 slightly over budget.

It's going to be difficult to find laptops that have a 4/5 battery life without sacrificing on performance. I have decided to curate 3 laptops an I think you'll see that it may be worth it to go for a slightly cheaper option that has much more performance. As a student it would be strange if you were to be in a position to code without any power near by (library, cafes, etc) unless you explicitly tried to code somewhere without power.

\n\n

You also stated that you wanted the laptops to cost less than 1,300$ USD, but since I am recommending laptops that you can purchase today to be shipped to Bulgaria, I had to use the exchange rate: 1.3k USD -> 2,063.75 Bulgarian Levs.

\u043b\u0432 2,068.97 at newegg, MSRP \u043b\u0432 2,483.46\n\"XPS

\n\n

This XPS 13 configuration has a 7200U processor. If you're not familiar with the Intel letter system, U stands for power saver, which means that the processor is designed for long battery life instead of performance. It also features 8gb of DDR3 RAM and a 128 gb ssd. It has no dedicated graphics card which will also help for longer battery life. This laptop is in common use by university engineering students in the US (usually in it's more powerful, less battery efficient variants in order to support 3D modeling).

\n\n

\u043b\u0432 2,987.85 at newegg, MSRP \u043b\u0432 3,586.17\n\"ASUS

\n\n

This laptop features a much more powerful i7-7700HQ Quad Core. It also features a PCIE NVMe 512 GB SSD. If you don't know PCIE ssd's are dramatically faster than traditional ssd's (up to speeds of 1+ gb/s read/writes) which will make heavy applications visual studio load much faster. It also comes with a thunderous NVIDIA GeForce GTX 1050 Ti 4 GB which will make any 3D/game programming a breeze. It also features a generous 16gb of DDR4 ram which have feature slightly faster RAM timings that allow for faster application load in (iex. visual studio).

\n\n

In addition this laptop features an 8-cell Li-ion battery, which will help with battery life. According to this review:

\n\n

\u043b\u0432 1,580.99 at newegg, MSRP \u043b\u0432 2,054.99\n\"MSI

\n\n

This laptop is the cheapest laptop among the 3, and has arguably the best components for the best value. It features a high powered Intel Core i7-7700HQ Quad Core, and additional discrete graphics card -GeForce GTX 1050 Ti 4 GB GDDR5, 512 GB M.2 SATA SSD (a little bit slower than PCI-E), as well as 16 GB of DDR4 RAM.

\n\n

As an additional note, this laptop will have the best keyboard among the 3 choices, as it is a gaming laptop, featuring MSI's signature anti-ghosting steel series keyboard. I personally own the GS-60 Ghost, and can say the keyboard is very good for a non mechanical keyboard.

\n\n

In terms of battery life the MSI is going to fall back, but in exchange you'll be packing a punch in performance and price.

\n\n

According to this review:

\n\n
\n

The laptop lasted only 3 hours and 33 minutes on our battery test, which consists of continuous web surfing over Wi-Fi at 150 nits of brightness.

\n
\n\n
\n\n

I highly recommend option 3, but if you absolutely demand a 4/5 hour battery life, you might as well buy a portable battery for laptops like one of these, and it will still be cheaper than the 2 options.

Special Considerations regarding Mac based application development (Swift)

\n\n

You've probably noticed that I didn't recommend any Macs. This is because they are not as \"friendly\" to application development as other operating systems, and tend to be overpriced if you buy them specifically for the hardware that exists in them. I personally program using the Xamarin technology to create universal, cross-platform mobile apps, but this requires me to have a mac available to even build and test the iOS version of my universal app. In order to get around this I use a Virtual Machine emulator, specifically VM Player with a special patch which allows me to run a mac virtual machine on windows.

The telling part is in the last part of that little chart. Note that it displays an 8+4+4+4 dual-channel configuration, but in reality, you're only getting 16GB of the 20GB you install in that configuration.

\n\n

That's normally a big sign that the 16GB RAM limitation is something tied to the motherboard chipset, and you're not going to get around it. In this case, I think it's just really lousy documentation on the part of HP. Be ready for contradiction. If you go to the actual HP support site, it says this motherboard's chipset can handle up to 32GB DDR3. That's a 4x 8GB. Another hint that the documentation you have is nuts is the fact that a configuration that reads 8+4+4+4 as dual channel is nonsensical. Memory won't run in dual channel mode unless the RAM capacitance is matched.

Could someone give any recommendations on which processor to go for, considering above requirements.

\n", "Title": "Intel Mobile Pentium N3710 vs N4200 processor for laptop", "Tags": "|laptop|processor|linux|", "Answer": "

Summary

\n\n

When it comes to considering processors directly, my preferred method of doing so is evaluating their online benchmarks. This allows you to rank processors relative to each other quite easily without actually having them on hand.

\n\n

In general, it looks like the N4200 is going to be the better choice as Intel's MSRP appraisal of both processors is the same at exactly $161.00

\n\n

Straight line performance

\n\n

Some of the immediate differences between the N4200 (Released Jan 2016) and N3710 (Released July 2016) is that the N4200:

\n\n\n\n

Power Consumption

\n\n

In terms of power consumption, each processor is estimated to cost about 1.25$/year, so there is no effective difference in power consumption, However; the N4200 will output about 12.8% more performance per watt making it more efficient than the N3710 variant.

\n\n

Memory Support

\n\n

According to the official Intel spec sheets of the respective processors [N4200 here], [N3710 here]:

\n\n

It appears that the N4200 is equipped to handle DDR3L/LPDDR3 up to 1866 MT/s, and LPDDR4 up to 2400 MT/s, while the N3710 only supports DDR3L-1600. This means that the newer N4200 processors will be able to handle newer RAM types with faster timings. This will effect the effective application load in speed.

\n\n

Interestingly enough, however; the N3710 supports twice the Maximum memory bandwidth.

\n\n

Special Considerations

\n\n

CPUBoss reports that the N3710 is capable of being pushed further via Overclocking than the N4200 by nearly (45.5% by air, difference is nominal if you are using water cooling (7%)). This is only applicable if your motherboard supports overclocking, or whether there are any linux based programs that you can control your processor speed from.

I'm looking for a little advice on how best to improve the performance of my machine.

\n\n

I'm using the machine for development of a game using the Unreal UE4 engine but I see some performance issues and lagging particularly when using the Unreal engine alongside other processes like Google Chrome.

\n\n

Ideally I'd like there to be a magic answer but I understand that I may be required to purchase some hardware upgrades to really see a performance increase. I'm guessing that a RAM upgrade to 16GB might not be enough but I'm really not sure.

\n\n

Would the processor be a bottleneck here or is the RAM likely to be more of an issue? If I upgrade the processor am I likely to need to buy a new case and motherboard?

\n\n

Either way, I'd like to keep the costs down as much as possible.

\n\n

My computer is a DELL Vostro 3900 but I've made some upgrades from the stock model.

\n\n

I have:

\nIntel i5-4460 Quad Core running at 3.2Ghz.\nDELL GGDJT Motherboard.(I haven't been able to find any useful documentation on this motherboard).
\nWindows 10 Pro
\n2x4GB DDR3 Ram for a total of 8GB (added after purchase).
\n1x3GB Geforce GTX 1060 Graphics card (added after purchase).
\n1x 180GB Intel SSD with the OS and Unreal engine/project files installed (added after purchase).
\n1x 500GB Seagate SATA drive for storage.
\n1x 500w power supply(added after purchase).

\n\n

Any advice is gratefully received.

Going off the fact that you claimed about 90% RAM usage during your typical use scenario, it is likely that your RAM is paging to SSD and degrading performance.

\n\n

Most of your specs are fine, so it is unlikely those are going to be bottlenecks. As an additional note windows typically only uses less than 4 gb, and chrome typically doesn't use more than 1gb unless you have a lot of extensions. That would leave 3 gb for Unreal Engine, though I am surprised that Unreal is using that much RAM. Unfortunately I don't use Unreal engine a lot so I don't know what the typical memory usage is. You might want to look into your applications and see if any are using inordinate amounts of memory.

\n\n

As for the recommendation, I was unable to find much information on your MOBO and the DELL support site wasn't very helpful. The spec sheet for your cpu was more useful:\n\"Intel

\n\n

I've recommended 16 gb of RAM as I think that this will be more than enough to ensure that your computer isn't paging to hard drive. To put this in perspective, I have 16 gb on a laptop and only come close to filling that up running multiple Virtual Machines in parallel alongside Visual Studio + Re-sharper.

\n\n
\n\n

This newegg query contains a huge list of RAM upgrades you could purchase for your computer sorted by price. I've made a specific recommendation below:

\n\n

Specific recommendation: G.SKILL Ares Series 16GB

\n\n

$125.99 at newegg\n\"G.SKILL

\n\n

I've chosen RAM rated at 1600 as your core specifies this is the fastest that it can support. The raised speed will allow you to load in applications slightly faster than if was rated at 1333. It also has the lowest CAS latency that I could find at 9 (specifically: 9-9-9-24). If you wanted to save money while maximizing for performance trade off, you could go for RAM with higher CAS latency, but it will increase the delay for your RAM.

\n\n
\n

Specifically: Cas Latency(ns)/frequency(mhz) * 1000 = response time(ns)

\n
\n\n

Therefore, if you bought a 1600 speed RAM with a CAS Latency of 11, it would have a delay of 6.875 ns which would be a 22.222% increase in delay from equivalent RAM rated at CAS Latency 9.

\n\n

It's been a while since I've looked into the RAM market, but I remember G.SKILL, and Corsair being heavily praised in the self-building PC community around the time the 4k series intel processors were out. The Nemix and Team Group RAM seemed to be a little cheaper but user reviews seemed volatile. I haven't had much experience with these brands so I don't know how reliable their RAM is. I decided to recommend the cheapest \"enthusiast\" brand that I could recognize, but feel free to buy a cheaper RAM even if it isn't G.SKILL or Corsair.

I have purchased a ASUS K20CE style pc for my son, which has turned out not to have enough \"omph\" for playing even modest modern 3D games.

\n\n

I went out and got a GeForce GT710 card for the PC (which matched one of the options that I could have ordered the PC with to begin with) but was faced with the problem, that the card did not fit the cabinet (times have changed much since I built my last PC it turns out!)

\n\n

I guess the motherboard is a mini ITX one. It has a single PCI Express slot, and the cabinet is slim. I have my eyes on some alternative GPUs, that may fit the machine, but I hesitate to order as I realise the system has an external power adapter of at most 90W. Most GPU cards advertise 300-400W power requirements, so I am starting to wonder if it will work at all.

\n\n

Does anybody have experience with such an upgrade or advice? The goal is not to make a monster gaming PC, but just a modest budget one.

\n", "Title": "Seeking advice for adding GPU to mini PC", "Tags": "|graphics-cards|gaming|thin-mini-itx|", "Answer": "

You might be able to fit a low-profile nVidia GTX 1050 or 1050Ti in there, and that card would allow some modern gaming, but that is definitely not a gaming PC. The GT710 is an old business-class video card that is often used to allow multiple monitors on the same workstation, but is as bad as some on-die processor video adapters when it comes to processing.

\n\n

I looked at the spec sheet on that machine; it's designed to be a multimedia micro tower. Even the top end configuration for it only has a GT730 video card, and thats not much better than the 710. It does have an available 90w power supply upgrade, but as you discovered, even the most basic gaming setup requires more than that.

\n\n

You've also got a problem with that Pentium or hurk Celeron processor. Those are flat-out too weak for games. If it's an Intel processor and it doesn't say \"i3\", \"i5\", \"i7\", or \"i9\" at the beginning of its name, it's just their low-power junk they sell for cheap, and most games won't run on them at all.

\n\n

Unfortunately, all I have is bad news. That computer won't fit your kid's needs. You discovered that \"cheap computer\" and \"gaming computer\" are mutually exclusive. I tried to find this machine for sale in the USA, but it looks like it would run around $200 if it were available here. A light gaming computer in that price range won't happen, unless you can pick it up used.

I want to build a silent PC, high end, mainly for playing games and working. With working I mean Visual Studio 2017, about 3 virtual machines and my average 20+ Chrome tabs running at once.

\n\n

I assume liquid cooling is much more silent for 2 reasons:

\n\n\n\n

The catch is I've never mounted a liquid cooling system before, so aside from theory I have nothing to work with. I'll walk you through my soon-to-be rig components, just in case there are any restrictions:

I don't know if any other components might be important towards the current matter (which is liquid cooling), please let me know if there's any problem with that.

\n", "Title": "ASUS 1070 Strix - Liquid cooling?", "Tags": "|cooling|", "Answer": "

It may be a touch more efficient due to the water convection of the heat works but water cooling still relies on fans to cool a radiator that cools the water. The thermal capacity of a liquid cooling solution, however, is a bit higher than just that of a heatpipe and a fan.

\n\n

You should see a marked improvement of both thermal capacity and overclocking potential of the machine with a water cooling solution but I would suggest that if this is new to you that you go for a self contained solution like this.

The radiator is quite large though, so you may prefer one of it's smaller versions depending on the size of your case.

We'd need more specific information about your rig for more precise advice, particularly given the age.

\n\n

Options (in order of estimated cost):

\n\n

1) Investigate if your current motherboard supports any fan control capability (eg. PWM) - you'll need to get into your BIOS, but it sounds like you have already tried this and found nothing that looks like this.

\n\n

2) Try a software solution like Speedfan. If the hardware supports it, you can manually control the speed of your fans.

\n\n

3) Buy a resistor ; you can get a short wire that you plug your existing fan into, and then the other end into your motherboard. A reduction in voltage means a reduction in fan speed and thus a reduction in noise. It will also mean a rise in temperature but 30C is very low for a CPU so you have plenty of headroom. Fan resistor calculator.

\n\n

4) Buy a new CPU heat-sink & fan (HSF) that is quieter and/or can be manually controlled. Getting one to fit Socket A/462 might be the challenge, and this will be proportionally very expensive. Decent modern HSFs would cost as little as \u00a320/$20/20\u20ac.... but can you find one to fit.

\n\n

5) Soundproof your case. Expensive, and why would you go to all the trouble/expense for such an old rig.

\n\n

Could you use your Noctua fan? Yes of course, but you could. The difficulty would be getting it mounted securely in a position to maximise the airflow. If your 60mm fan is directly over the middle of the heat-sink, you'll probably find your 120mm fan would be offset to the side so the larger hub does not block airflow. You could combine this with #3 to reduce the speed/noise further.

\n\n

Caveat: you would need to monitor temps to confirm that your final configuration is cooling the CPU sufficiently.

\n\n

As a general rule, the warmer the temp, the shorter the CPU lifespan. So your noise reduction might accelerate this CPU's demise! On the other hand, it's lasted this long, and who's to say that you haven't got lucky with a very good chip. The cut out temp for that chip is likely to be in the 90C area, so Id suggest you don't let it get above 60-70C for too long.

The few times I've encountered server gear, the build quality simply amazes me. It's just remarkably well-built, with incredibly solid metal construction throughout. The quality of the front of the chassis and branding, in particular, lend a sense of gravitas I simply don't get from any consumer desktop chassis I've seen. High-end workstations from major PC vendors are often built to a similar level of quality as well.

\n\n

I realize that with the profit margins typical of high-end IT equipment, vendors can afford to spare no expense on the physical construction of their products, and that it's hard to achieve the same in the price-sensitive consumer market. Nonetheless, are there any modern (not discontinued) consumer- or gamer-oriented desktop chassis built to \"big iron\" server standards?

\n\n

I'm looking for high-quality, rigid metal construction in all key areas, with judicious use of plastics only where it does not significantly reduce build quality. There should not be thin, low-quality material that is easily bent, dented, or otherwise damaged. This extends to key interior parts of the case, such as the drive cages. A high level of durability is also expected of any supplied accessories such as pre-installed fans. Branding and design motifs should be physically substantial, extending beyond mere printing on the chassis.

I personally use the Thermaltake WP200. That is, the W200 core chassis atop the P200 extension chassis.

\n\n

It follows the \"if it's interior, it's metal\" approach, right down to the removable motherboard tray on one side. It currently houses TWO computers and came with power and USB headers for both; my i7 2600k on one side and my i7 8700k on the other, both overclocked and both with the massive Noctua D15-class heat sink and fans mounted on them without affecting case clearance. Both use an EATX motherboard. The case comes with no fans (nor should you typically trust a fan that comes with a case), but instead has mounting racks for multiple configurations. Right now, the whole machine is air-cooled. I have about 30 case fans running either in the case mounted modules, face panel, or on the actual heat sinks.

\n\n

The P200 section serves mostly as where I manage my power connections and cables, as it contains induction fans and two 800w power supplies to supplement the 1200w one in the W200 area (and if I didn't use the EATX on the side with the removable mobo tray, I could have fit another 1200W there as well).

\n\n

The drive racks are plastic, but it's a durable plastic, and they're made of plastic to keep them light. This is because they can mount more than one way. While the racks can fit in metal modules for the face of the machine, I reserved that for optical drives, a hot-swap bay, and headers. Instead, I use the plastic racks to \"hang\" the drives into clip-lock bays that are on one side of the metal divider on the inside of the case, which makes swapping them easy if I want. They use plastic locks instead of screws to hold the drives, which makes for quieter HDDs and easier replacement.

\n\n

Obviously, it comes with modular connections that assist with cable management, and can fit multiple radiators for elite watercoolers. The case can accept 120mm and 140mm fans in the same fan bays and racks. The racks for the fans or radiators all hold with steel thumb screws so they are steady and I don't have to just depend on the optional plastic locks that can hold them into place (this case allows you to be lazy, I guess, but you don't have to be).

\n\n

Fan induction points can be covered with a magnetically-fixed metal screen that comes with the unit (one for each potential point). This keeps dust out and extends fan life, and makes cleaning your fan filters as simple as just a quick wipe over the trash can.

\n\n

You can use rubber feet, but this thing is HEAVY when it's fully assembled and loaded with tech. We're talking 85-125 lbs depending on what you put in it. This upgrades your computer to furniture. I highly recommend using the castors it comes with instead of the feet, so you can just roll it around to move it. Otherwise, get a dolly with some straps.

\n\n

The only complaints I have are its loaded weight and the way the external panels fit. They connect via plastic knobs (thick and durable) that are grabbed by plastic tension brackets in the external panel (replaceable but sort of flimsy). The panels never fall off, but the top lid is currently missing one of its tension brackets, which makes correctly aligning the top and locking it in place a little annoying.

\n\n

Edit: Also, the panels can be detached for painting so you can safely customize yourself if you want without harming the tech. The Thermaltake \"TT\" logo is on the face panels, but is otherwise kept minimal.

I have some conductive ink that I want to use to print circuits. The current method involves painting the ink, but I would like a more precise method.

\n\n

I am aware of YouTube videos and such explaining how to refill an ink cartridge for an inkjet printer myself, but I would rather not use a cartridge that was previously filled with regular ink in order to avoid contamination.

\n\n

Are there any printers that cater to this niche market of people wanting to use odd inks?

\n", "Title": "Are there any printer companies that sell empty ink cartridges that I can fill myself?", "Tags": "|printer|home-electronics|", "Answer": "

Printer companies specifically avoid doing this because their margin only comes from ink sales. They usually lose money on the printer itself. This is true of most accessory-based consumer electronics; Microsoft loses money on every X-Box line of product sold, and makes a killing on licensing developers to make its games and online marketplace surcharges. When I worked retail, a Lexmark rep once revealed to me that we were buying cartridges for $20 that we were selling for $45 and that Lexmark only spent $1 per cartridge to manufacture and ship them, but that they averaged a $10 loss per printer they sold, and that loss carried forward. That's why the guy at the store just shoves ink in your cart without asking, and why the printer ships with half-filled ink and calls it a \"starter\" half the time.

\n\n

This means you have more to deal with than just cleaning the cartridge. You need to know your cartridges a little.

\n\n
    \n
  1. Don't do this with an HP inkjet. They integrate the printhead onto the cartridge, which is sort of nice, but they also sometimes rig them to detect inks of a different density and refuse to print. I don't have a link for that one, but I've seen it happen. If the ink is thinner, it may fail to detect, but the custom head may just vomit ink all over the page because it's expecting a certain density. Even just normal ink refills with them takes a little care, and ink quality matters.
  2. \n
  3. Lexmark will work, but not all of their cartridges are refillable.
  4. \n
  5. Single-color cartridge printers (i.e. C, M, Y, K are in their own containers) are ideal. Brother, some Canon, Xerox, and Epson all do this. They warn that using your own ink voids your warranty, but the cartridge will accept the ink. Also, many of the cartridges are clear, so you can visibly see the fill level, and you don't have to worry about screwing up filling a tri-color cartridge.
  6. \n
\n\n

Knowing the above, I'd advise starting with Item 3 on the list; get a printer that uses single-tone, individual carts. Got one? Great. Clear cartridge? Even better. Now to prep the cartridge.

\n\n

You don't want to soak the cartridge in bleach or vinegar. Bleach is a bad idea anyway as it leaves a residue which may affect the ink. Vinegar will break the dried ink up and flush it out, but it's likely to damage the rubber seals on the cartridge or expand the rubber so that it doesn't fit right anymore. Always start with hot water and just observe the cartridge contents to see if it flushes (clear cartridge benefit, of course). If you get all of the ink out, great. If you have splatted hunks of dried ink inside, then vinegar might be your only (safe) solution, but don't let it stand for long, or you can damage the cartridge as mentioned above.

\n\n

Allow to dry before refilling with your ink. Keep in mind that a viscous ink and a watery ink aren't the same thing; if your printer normally dumps thin ink and you put in conductive ink, it may give you some spotty or splotchy results. I'd start small, here.

The real problem is that the difference between an external hard drive and an external hard drive enclosure is whether or not there's a drive in it. Most of the manufacturers sell the enclosures separately, and those enclosures have little-to-no shock absorption when dropped. This is because an HDD is intended to be a stationary form of media. SSD have no moving parts, so rather than perfect the enclosures, the preference is to use SSD. It's also common to use BD-ROM, if it's read-only media, because they have a decent lifespan.

\n\n

Also, remember that the average hard disk only lasts three to five years in perfect conditions.. This is part of why datacenters are all dropping the HDD in favor of the SSD.

\n\n

A thing in common with all of these enclosures is that they won't fit some of your optional requests.

\n\n
\n

Support multi-disk integration.

\n
\n\n

I think you mean an enclosure that fits multiple drives at once. At that point, it's expected you want a NAS, so you usually just find small computer cases for this.

\n\n
\n

Have the independent power supply.

\n
\n\n

All of them have this.

\n\n
\n

Have dust resistant design.

\n
\n\n

This requires an airtight seal, effectively. That drastically increases heat, which is a drive killer. Most cases for HDDs actually have fans to dissipate heat or vent holes (pictured) to prevent trapping heat against the drive. This outlines your need for something which isn't sensitive to dust due to a lack of moving parts (i.e., an SSD). Even if it's sealed properly and cooled, the seals are rubberized or foam and wear with time.

\n\n
\n

The SATA interface of the case is attached at the end of a cable, instead of fixed on the case. (to enable the flexibility of hard disk length (even if disk size is 3.5 inch, but I need to add a SAS to SATA adapter when I gain SAS HDD)).

\n
\n\n

I see the problem, but integrating a cable is never a solution. SATA cables are cheap, simple cables that need replacing from time to time. SATA extension cables are readily available for power supplies with a SATA connector, for about $3 US a piece. You can get long SATA cables similarly. These plug into my SAS->SATA adapter just fine ($15 part on Amazon).

\n\n
\n

The frame of the case can be easily disassembled and reassembled with a standard screwdriver for cleaning and maintenance

\n
\n\n

You can't have this and a dust-tight seal, most of the time.

\n\n

I'd take a step back and look at your problem. It sounds like you need to store Terabytes at a time in a portable manner, but that data may be rewritten in full repeatedly. While you have drives now, you're looking at spending around $100 on specific, high-quality external components per drive. You're in an environment where small particles are a factor and interfere with your moving parts, and you're trying to plan around SAS drive compatibility (which means 15000 RPM Server HDD). With all of that, your expenses will build rapidly. For a bit more, you can just start using enterprise-level SSD like Amazon Web Services and similar use. For around $250, you can get an SSD @ 1TB and $400 gets an SSD @ 2TB. They generate less heat, are less heat-sensitive, have a lower TDP, have no moving parts, are completely enclosed to prevent contact from dust, and can take a drop without losing data. While an SSD ages faster if you write to the whole drive repeatedly, they still last physically about twice as long as an HDD and don't suffer from fragmentation issues. For your needs, that's a better way to spend your money.

\n\n

If you absolutely must use your HDD in a portable manner, I recommend a dock and a carrying case as two separate components. Something like this would one-shot handle your portability needs, and you can just plug in and use the drives in a dock to purpose. To fit your SAS needs, all you'll need to do is find a dock that exposes its internal SATA connection so you can connect your adapter.

I am looking to go big on cores and have bought the Intel i9 7980XE 18 core processor. I'm trying to find a sane list of parts that will be compatible - I haven't built a computer for about 10 years and things have changed!

\n\n

One thing i'm wondering is about the storage. They seem to be recommending 5 hard drives. I've never heard of these nvme m.2 drives before but presumably if I only need a small amount of storage then the 512GB m.2 one will be enough for everything, no need for the 1TB m.2 or the other SSDs right?

\n\n

Will the 650 Watt version of the power supply (https://www.amazon.co.uk/Seasonic-Prime-Titanium-Modular-Supply/dp/B01HXYRJYK) be enough to fuel everything?

\n\n

I don't need a mega graphics card. This isn't going to be a gaming machine and all I need is to connect an HDMI screen. Can you give me a reason to not get a really cheap graphics card like this? https://www.ebuyer.com/806221-asus-geforce-gt-710-graphics-card-gt710-sl-1gd5

\n", "Title": "Intel i9 7980XE Are these parts compatible?", "Tags": "|graphics-cards|processor|motherboard|hard-disk|power-supply|", "Answer": "

Knocking through the questions:

\n\n
    \n
  1. Storage is really up to you. M2 drives are just a really fast connection that enjoys about 4x the write speed of SATA. This means, from the perspective of a user, near instantaneous reads and writes. Beyond that, it's basically the same technology as a normal SSD, so you're talking quarter seconds versus full seconds. If you're making your storage decisions based on speed, SSD and M2 are the way to go. Same for longevity, as they last a couple of years longer than a classic mechanical HDD. If you're basing it on capacity alone, you would obviously want HDD, but you may prefer a BD-RW that can write to M-Disc and a few of those discs for your long-term, read-only media like pictures of the family. The expense is higher but you'd get better storage than any of the other solutions for longevity.
  2. \n
  3. With all of that hardware, a 650w PSU will be cutting it close, especially with a 1080ti in there (we will get to that in a second). The PSU is one of the most important purchases in a PC or server build of any kind. I'd look in the 850w+ range from a company with a good reputation and support like Antec or EVGA. The CPU may be an extremely important part of a computer purchase, but without the PSU, the CPU is just a block of expensive and cold silicon. With a bad one, your whole build can die in a literal fire. Never skimp on the PSU.
  4. \n
  5. If you don't plan to game and aren't buying four of them to mine bitcoin and make gamers hate you for inflating the price even further, you don't need the 1080ti. Not only is this WAY overpowered if you are just using the machine for a server and HTPC, but it's also not financially wise right now. Video card prices are horribly inflated due to the fact GPUs are what you use to mine cryptocurrency, and it's killing the supply while the craze continues. I wouldn't bother with the GT-710, though. It's an older card. Honestly, if the most you plan to do is watch a movie as far as graphics are concerned, I would just get a 1050 or 950. That motherboard doesn't appear to have HDMI out; if it did, I'm pretty sure you wouldn't need a video card, as I think the i9 still has the on-die video capability that the other series processors have.
  6. \n
\n\n

Just as a personal note, if you're not primarily running this as a server, that i9 won't get put to use. Modern processors for personal use typically cap out at the next step down. The i9 and the AMD Threadripper are specifically intended for massive amounts of multitasking and multithreaded activities such as video encoding (as in, from scratch in a video editing environment) or server-grade shared processing. If you're not using this for a professional purpose like that, you will save money and even get increased performance out of an i7 or an i5 in comparison. Please note in this benchmark that a new-generation i7 that costs 1/6th the price outperforms the i9 you have selected in applications that use less than 5 cores; that's 90% of the consumer software market. File server use won't change much between processors; that's not a CPU intensive activity. If you plan to host applications for your whole household or business to be clients to this as a server, however, the i9 would be more worth it.

I need a mini speaker which looks like a flash drive and uses USB for both power and data (so it doesn\u2019t use 3.5mm audio jack) for a Raspberry Pi project. It doesn\u2019t have to be

\n", "Title": "Mini USB Powered Speaker", "Tags": "|usb|audio|mini-pc|speakers|", "Answer": "

You've got a couple of problems with your spec and will need to work around them to proceed.

\n\n

First, a USB connected speaker would need its own audio adapter onboard, or drivers that interface with the audio adapter on the host machine and a board in the speaker to convert the digital signal to an analog form internally. Outside of headphones, there's not a lot of demand for that, so you may be searching for a product that simply isn't.

\n\n

Second, the output of a speaker is limited by the amount of power which it can receive. The voltage available is only 5 volts, and in all forms the maximum current is less than a full amp (.5 for most, .9 for USB 3.x). Depending on the USB port, that gives you under 5 Watts to work with. At max volume, you're looking at 93-96 decibels, but keep in mind that the above is peak for the USB port, and some of that power will go to converting the digital signal to analog. This means your actual results will probably be closer to 75-80db, which gets you not much louder than a conversation. Speaker size also matters, and this will inhibit the max volume the speaker is physically capable of putting out there. A speaker that is under 2 inches is going to output so little sound under the power a USB port can give it that your audio will require a quiet room or your head close to it to hear it.

\n\n

Small electronics usually wire an analog speaker directly into an onboard component, and if you disassemble something like an old Tiger handheld game, you'll find that tiny sound was produced by speakers that still took up a large chunk of the case. The way headset designers make it work is through additional components you don't have available that increase the size of their solution. They also have the benefit of the speaker being so close to your ear that the overall output power is less important. USB sound cards do something similar, and you'll find that all external sound cards that produce powerful, non-headset sound use a secondary power supply plugged into the wall.

\n\n

My recommendation would be to use a Bluetooth adapter in the USB port, and use a battery-powered rechargeable portable speaker. Those you can find all day long, resolve your audio quality and power problem, and your analog audio jack will remain open. It's been awhile since I worked with a Pi so I don't know how hard it is to get a BT stack set up on one these days, but it's a wheel that already exists.

The next item affecting overall (general) performance is memory speed! Not memory amount. 8GB is plenty but that 1st choice has memory running at 3000MHz. So pick #1.

Which one is better? Recently, I've never used monitor. So I don't imagine which one is better to me.

\n", "Title": "Which monitor would be better to programming?", "Tags": "|monitors|multiple-monitors|", "Answer": "

Both of these monitors are 1920 x 1080, 60 Hz monitors. The primary difference is their physical size. The benefit of the larger monitor is that (assuming you would have each at the same distance from your eyes) you will be able to lower the display scale on the larger screen and potentially fit more in view.

\n\n

Note: there will be substantial loss in visual fidelity. The smaller monitor will give you about 50% greater pixel density than the 32\" screen. The flipside is that obviously the larger monitor will be more comfortable to look at from a further distance, and for tasks that require less fine detail (such as watching non-bluray quality movies) the larger monitor will just be more pleasing to look at.

I have a desktop running an i3-2100 (LGA 1155 socket). The desktop is close to a decade old at this point and still running the stock Intel fan (this one), which is also incidentally the only one in my mid tower apart from the one on the PSU (a Corsair VS550), so I'm looking for an aftermarket replacement that is both quieter and more effective at cooling. I'm also on a low income, so I really need it to be cheap.

\n\n

So far I've found this one, and will probably end up going with it unless someone here informs me that it will actually perform worse than stock or there's a much better option for very close to the same price point (talking a difference of around \u00a35).

Arctic Cool Freezer Pro 7 r2

This is my go-to budget cooler. Much quieter and a better cooler than stock HSFs.

\n\n

Also buy some decent-but-cheap thermal paste, such as Arctic Silver 5 and Thermal Grizzly Kryonaut.

\n\n

Combined, these should set you back 25-30 GBP/USD/Euro.

\n\n

Also perhaps look at some fan-control s/w such as Speedfan - even when you can't improve temps, you can change how your fan responds to them. Some rigs crank up to 100% fan speed too early.

\n\n

EDIT: The Freezer Pro 11 LP is a low profile alternative. With LP coolers, compromises are made (i.e smaller and directed into case, rather than to rear), so it will be harder for it to keep the same CPU cool in comparison. However, this one is still cheap and still quiet.

I'm looking to update my current gaming and work laptop to something featuring the latest CPUs and GPUs. Unfortunately, 120 Hz FHD screens seem to be more popular than 4K this year.

Preferred but not necessary:

\n\n\n", "Title": "4K gaming laptops with up-to-date hardware?", "Tags": "|laptop|gaming|pc|", "Answer": "

After extensive searching, I found a few options.

\n\n
    \n
  1. Eurocom X4C. This is what I eventually ended up buying. It has up to 64 GB of RAM, two M.2 slots, the desktop 8700k, and 1080 GPU, and a selection of several different screens, including on UHD version. It's also 15.6 inches, so pretty much exactly what I was looking for. The only issues I'd mention are that it's somewhat prone to backlight bleed, and, like most computers built on a Clevo chassis, has a little give in the keyboard.

  2. \n
  3. Hidevolution Evoc P750TM-1. It seems to be built on the same chassis as the previous, and has similar specifications. One advantage is that it comes with up to 2800 MHz RAM, rather than the 2400 MHz standard on the Eurocom.

  4. \n
\n\n

There are a few other options I found (e.g. from Acer) that had a 4k screen, but either had \"only\" 32 GB of RAM, came with only a 1070, or both. If these aren't obstacles, one of these laptops might be the better choice, since they're much more professionally put together.

I am planning to buy a laptop. I am not in a huge rush. So I can perfectly wait another 3/4 months with no issues. I am looking for a laptop to work mainly. I will mostly remote from it to my office desktop so a very good screen and keyboard are important so that I can perform multiple tasks simultaneously while remoted. Stuff that I care about:

\n\n

1) Processing power - I run heavily computational stuff (paralellized codes). I mainly use my desktop for those, but would always be nice to have the option of running some lighter stuff on the laptop (not very important)

\n\n

2) Graphics card - I played a lot of games more than 10 years ago. I would like to start playing again. With cloud gaming coming soon mainstream, maybe it is not that important to have a good graphics card. I would mostly play tomb raider, csgo, pubg.

\n\n

3) Durability/Longevity - This is important for me. I would like the laptop to last under normal usage.

\n\n

4) Portability - I travel once every other week and need my laptop.

\n\n

With so many tradeoffs not sure what should I buy. I compiled a list below with 5 laptops I narrowed down. The last 3 lines are my personal opinion.

Don't worry about cloud computing when it comes to graphics adapters; at this time, there's no realistic way to process high-definition graphics and then pitch them to a screen at 60 frames per second over distributed computing vs. a card on a PCI-E bus. Going off of your diagram:

\n\n

Macbook Pro:

\n\n

The issue you'll have here is largely tied to your code. The machine will swallow some exceptions and bury them in a log that only an Apple \"Genius Bar\" can access. You also get less hardware in the machine for more money, and have the usual compatibility issues with having Mac OS instead of Windows. The hardware is actually still just the same stuff you'd see in a Windows PC, but your service is handled through Apple. The only exception is the Retina display, as these are exceptionally clear and color-balanced out of the box. You may have noticed in the diagram that competitors now offer similar hardware here, as well, which closes this gap. 4GB of texture memory on the video card is just enough to push this resolution if you decide to game or do any 3D design work.

\n\n

Lenovo X1:

\n\n

Having first-hand experience with the display on this one, I can tell you that it's one of the best. It's not as high-res as two of the other offerings, but it's matched well with the maximum capabilities of the graphics adapter. Unfortunately, said adapter in this case is the on-die Intel adapter that comes part-in-parcel with an Intel i7-8550U. The U stands for \"underpower\" in Intel SKUs; that is to say, the processor is underclocked and under-spec in order to provide significantly longer battery life. The 8th-gen U-series are the first to offer quad core options, but any demanding computing is likely to be inhibited by the product. It's very light, though, so if you have access to a desktop at home with better specs, this makes a great portable work machine.

\n\n

Gigabyte Aero 15x:

\n\n

Gigabyte is a big name in motherboard manufacturing, similar to Asus but without the weird stigma that some business-types add to the \"Republic of Gamers\" sticker and price premium added to the Asus laptop shells. A gaming laptop is just another term for \"most powerful laptop available\" and in no way suggests the machine isn't ideal in a work environment; computer design progression is pretty linear when it comes to that sort of thing. The unit is larger and heavier, but with good reason; you get the newest, proper \"H\" series of i7 processor in it, with the very powerful 1070GTX from nVidia with all of its lovely texture memory. This unit is effectively a portable desktop.

\n\n

You're limited to 1080p resolution on the monitor. On the surface, that sounds, bad, but in a laptop, it's really not. Modern LED screens at high resolution use \"scaling\" to make icons and text larger. If you leave them at their native sizes, they become too small to read properly on an Ultra-High-Definition display when the display is only about 14-15\" diagonally across (which is how screens are measured). If you're not doing graphic design or gaming at 4k+ resolution, anything more than 1080p in a laptop is usually a waste.

\n\n

The only other downside I can see here is that with all that power, battery life will be shortened. This is why you always see gaming laptops plugged in; you only get 2-3 hours out of the battery if you're doing something that really takes advantage of the machine's sheer processing capability.

\n\n

Overall, this would be my pick given the choices.

\n\n

Dell XPS 15:

\n\n

This machine is a good compromise, and has the highest-resolution display of the lot. You'd definitely want to scale your desktop a little in order to see clearly for daily use, but you get some nice hardware here for the price. The only real loss here vs. the Gigabyte is that the video card is less powerful and has half the texture memory, which can make for a slow gaming experience on newer games (especially if they support resolutions higher than 1080p).

\n\n

The reason it's easier on the wallet is because the processor inside is a generation behind the one in the Gigabyte, but it's still a very good processor by today's standards and I strongly doubt you'd see a difference. I'm not a huge fan of the Dell brand, but I think you'd be pleased with this unit as well. You will likely get longer battery life out of the Dell due to the lower power consumption of the graphics card.

\n\n

Conclusion:

\n\n

I would go with the Gigabyte if price isn't an issue and you can reach an outlet when you're doing anything particularly intense. Barring that, I'd recommend the Dell. If battery life is the most important criteria, Lenovo's will have the best. I wouldn't bother with the Apple.

The relevant part of my system is straightforward - a Radeon R9 370 card with HDMI + DisplayPort output. The monitor is a 4K (3840 x 2160) Dell UltraSharp UP3216Q with HDMI 2.0 and DisplayPort connectors.

\n\n

My underlying problem is the well-known issue that when the monitor turns off, or the second monitor changes, my windows all move around. I've tried a number of fixes but none work well. Those that do, work by forcing the EDID values in Windows, which means if I do disconnect or change the monitor (as opposed to just turning it off), it still thinks there's a 3840 x 2160 attached, when it should resize to a smaller screen :)

\n\n

My solution is to move to a pass-through EDID emulator to solve this properly. The intended effect is that if I turn the monitor off but the cable is still connected, Windows will see it (due to the emulator) as still connected, and windows won't move round. But if the cable itself is unplugged, the EDID emulator will be disconnected with it and Windows will see a change of monitor or loss of monitor instead, which is ideal behaviour. That should fix it, if the EDID emulator works as expected.

\n\n\n\n

The problem is that 3840 x 2160 DisplayPort pass-through EDID emulators are either extremely new on the market, or not on the market yet, and I want this now :)

\n\n

My proposed solution is to notice that my monitor has HDMI 2.0 as well as DisplayPort. That means I could feed it 3840 x 2160 on the HDMI port and use an HDMI EDID emulator instead. Unlike DisplayPort, I'm pretty sure that 3840 x 2160 HDMI pass-through EDID emulators are much easier to find on the market and cheaper too, and this would solve my Windows problem equally well.

\n\n

My adapter's HDMI output is already in use, so I would need to get a DisplayPort to HDMI adapter as well. The connection would be:

\n\n\n\n

I'm guessing I will need an HDMI 2.0 emulator and adapter for this resolution. My questions are the obvious ones:

\n\n
    \n
  1. Will an HDMI EDID pass-through emulator work correctly \"behind\" a DP to HDMI adapter?
    (I can't think of a reason it wouldn't but you know how compatibility and media changing can be. I could be wrong.)
  2. \n
  3. Can DP to HDMI adapters, and HDMI EDID emulators be found, that work at 3840 x 2160 @ 60 Hz? 2. Will HDMI 2.0 handle it? Are all adapters/emulators pretty much equally reliable for this kind of need, or should I go for a specific buty more expensive brand?
    (Cheaper is best if possible!)
  4. \n
  5. If it'll work, what would be a recommendation for the cheapest \"known good\" adapter and emulator I should get?
  6. \n

Thanks for this BTW. I had a similar situation: DisplayPort ports on computers, DisplayPort switch, DisplayPort monitor. And of course, the windows jumping around every time I switched the monitor.

\n

I tried and tried to find a pass-through EDID adapter for DP to no avail. All I could find were headless plugs meant to fool some server's GPU that it was attached to a monitor. So I tried to duplicate your setup.

\n

I tried to do DP -> DP-to-HDMI converter -> HDMI EDID pass-through adapter -> HDMI-to-DP converter -> DP switch -> monitor. This worked OK for 2560 x 1440, but it was still unreliable, failing about 10-20% of the time, leaving me with the same moving windows. What I finally did was this: ditch the DP switch and use an HDMI switch instead. Here's my setup:

\n

Computers with DP output -> DP-to-HDMI converter -> long HDMI cable - HDMI EDID pass-through adapter -> HDMI switch -> HDMI cable -> monitor. I have been using it for 11 months now with solid reliability for the monitors.

With the help of the information in the http://www.hifi-remote.com/ (especially the forums), it's really easy to program with any OS: it mounts as a USB drive, and using Remote Master it's just a matter of copying a file with the configuration. Specifically, this the configuration file I just created for the NAD D 3020 (without using the original remote at all), and it works like a charm.

Features an i7 7th Gen 7500U. If you're not familiar with the Intel lettering system, U signifies that the laptop is a power-saving laptop. Effectively this means that the cpu speed is reduced to achieve longer battery life and energy efficiency. While not breaking any land speed records, will be more than enough for basic coding and internet surfing. Don't expect to run heavy IDEs like Visual Studio without some lag. This option's CPU is about 59.7% slower than option 2 according to it's average cpu passmark benchmark. It also comes with 1 TB HDD and a 256 GB SSD, for a total combined storage far above your requested storage amount. The laptop also features 8 GB DDR4, which you shouldn't come close to filling up in any normal user case scenario. I've even managed to fit in a dedicated graphics card, the NVIDIA GeForce MX150, but that's really gratuitous at this point. You might actually be able to play some really visually intensive 3D games at really low settings.

i'm setting up a computer with an LGA1151 cpu socket, and i'm looking for the cpu that would use the least amount of electricity for this motherboard. the cpu will not be stressed in the slightest, and does not need to be fast. i already have a computer doing the same tasks, running on a 2-core 35W TDP i3-7300T with hyperthreading disabled, and cpu frequency locked to 800MHz, and htop reports the cpu usage as being roughly \"5-8% per core\"

\n\n

going by TDP, it seems the 25W TDP Intel Xeon E3-1235L V5 is my best bet, but i don't know if TDP is a good indicator, because that's \"power consumption during high-intensity workloads\", which is not what i'll be using it for.. suggestions?

\n\n

(also i'm confused at how the 4-core Xeon can use less power than all the 2-core / 1-core alternatives, going by TDP, but i guess that should be a separate question)

\n", "Title": "LGA1151 CPU lowest power consumption?", "Tags": "|processor|power|high-end|", "Answer": "

TL;DR: Get a Celeron G3900 instead.

\n\n

Although you are correct in that the Xeon E3-1235L v5 and Xeon E3-1240L v5 have the lowest rated TDP (both at 25W), I would recommend staying away from these processors.

\n\n

Power consumption

\n\n

One thing to understand straight away is that under most conditions, the actual power consumption of the process will not be equal to the rated TDP. The rated TDP only measures the maximum thermal output the processor is capable\u2013that is, under full load. For example, the i7-6700K is rated for 91W, but only consumes 3.4W at idle. Note that this does not necessarily scale with rated TDP: the i3-3240 and i7-3770K have vastly different rated TDPs, but both consume roughly the same amount of power at idle.

\n\n

One thing you've noticed is that L and T series processors can consume significantly less power, even at idle/low load (although I'm not entirely sure what Intel does under the hood to do this.) However, this difference isn't necessarily huge\u2013especially given their lower performance due to lower clocks.

\n\n

Given the nature of what you're doing, I wouldn't expect the CPU to be under full load most of the time, and therefore, I don't believe it makes sense to buy an L or T series processor given...

\n\n

Cost

\n\n

The cheapest L series v5 Xeon (the E3-1235L v5) has an MSRP of $250.00 (if you can find one at all.) Meanwhile, the Celeron G3900 is only $30.61 with a rated TDP of 51W. At the US average of $0.12/kWh, even at full load, it would take roughly 8 years of continuous usage to offset the cost differential between the two processors. It simply doesn't make sense to buy a more expensive processor.

\n\n

Compatibility

\n\n

The final nail in the coffin is that v5 Xeons simply aren't compatible with motherboards with consumer chipsets\u2013including B250. While you could get a lower TDP consumer CPU, the price differential (a delta of $67.38 as of right now for the cheapest T series processor, the i3-7100T) probably isn't worth it.

I am a IT professional, recently got into learning Video Editing for YouTube content creation. Currently I have tested few video editing tools on a laptop with below specs and the render times were devastating and frustrating.

Thanks in advance!

For budget, don't go with a laptop unless portability is essential for you. Although the performance gap between laptops and desktops has shrunk with recent CPU and especially GPU series, a laptop capable of good video editing will still cost a lot.

\n\n

I'm assuming that you're looking for something under \u20b970,000 (1029 USD).

\n\n

For price, I'd highly recommend building your own desktop. You'll probably save a few hundred US dollar in labor right there—not so relevant for multi-thousand dollar machines, maybe, but for a budget device it's OK.

\n\n

The recommended requirements for After Effects are modest, simply a multicore CPU and 16 GB RAM. To get good performance, you'll probably need a little more than that. I'd recommend an i7 CPU (or the AMD equivalent).

\n\n\n\n

This totals about $1050 for a mostly new system. It should be very much capable of dealing with After Effects. It's slightly over your maximum (and I haven't included fans, power supply, etc.) but you can slice a little off by getting a lower tier motherboard (save $70), or a 250 GB SSD (save $70), or by getting the RAM used. Using a 6700k (two generations older, but similar speeds and can be overclocked anyway) could also save you a little.

\n\n

I won't talk about fans, etc., since they'll contribute relatively little to the price.

\n\n

If you really need a mobile system, it's going to be much harder to find a good one. There are a few good options, though, such as the Acer Aspire VX 15. This has a 1050 Ti GPU, about 16 GB of RAM, and a 7th-generation i7 CPU. Storage is minimal, though, so you'll end up needed an external hard drive, and as a laptop its performance will certainly be lower than than a desktop of similar price.

I'm looking to get a second monitor for my 2018 27\" iMac.

\n\n

The Dell P2715Q seems to be a common choice. It comes in 27\" and 24\" sizes. The first review on the Amazon site says that

\n\n
\n

the 24\" has the highest pixel density for the resolution -- if you go\n up to 27 or 28\" you will get excellent resolution but not as crisp\n text

\n
\n\n

Can anyone verify this? Or does anyone other suggestions for an external display for an iMac?

\n\n

I will be mounting this second monitor in portrait mode, and using it for coding and reading. I value really clear text, the way my 5k monitor for the iMac provides. I especially like that zooming in with the trackpad preserves the clarity of the text. (Though this may be true for every hi-res monitor.)

\n\n

My plan is to connect the monitor to the iMac with a display port -> USB-C cable.

\n", "Title": "24\" external monitor will have crisper text than 27\"?", "Tags": "|monitors|displays|", "Answer": "

The review reflects a general rule about monitor resolution; given the same resolution, a 27\" monitor will be slightly less clear on text and fine lines than a 24\" monitor. This is where pixel density matters. Unfortunately, this isn't measured the same way a monitor's screen is measured, as pixel density is about how many pixels there are per a standard unit of measure, but monitor size is measured by the total screen length from the lower left corner to the upper right. Just like that one South Park episode, they measure at an angle to get a higher number.

\n\n

1920x1200, 24\" \n3840x2160, 27\"

\n\n

1920*1200 = 2,304,000 pixels\n3840*2160 = 8,294,400 pixels

\n\n

Both of these resolutions have a 16:10 aspect ratio. We now have all of the numbers we need to determine quite a lot about the monitor. We have the hypotenuse of a right triangle (24\") but we have a different standard of measure for the sides (1920px L, 1200px W). We can use the Pythagorean Theorem to determine what '24\"' means.

\n\n

1920sq + 1200sq = 3686400 + 1440000 = 5126400

\n\n

sqrt of 5126400 = 2264.155471693585

\n\n

3840*2160 = 14745600 * 4665600 = 19411200

\n\n

sqrt of 19411200 = 4405.814340164597

\n\n

Now we know how many pixels lie across that hypoteneuse for each monitor at the given resolutions. This lets us determine an estimate of density by ratio.

\n\n

2264.155471693585 / 24\" = 94.33981132056604 approx ppi diagonally.

\n\n

4405.814340164597 / 27\" = 163.1783088949851 approx ppi diagonally.

\n\n

Clearly, the higher resolution monitor here wins out. That's because the 4k monitor is nearly double the resolution, and is not double the size. The user who left the review likely had trouble seeing some things clearly on the 4k monitor because they were shrunk in size as a result, and lowered their resolution to 1080p; 1080p is not the native resolution on the monitor, and will appear blurry by comparison. This will also happen in fullscreen apps which do not support higher than 1080p.

\n\n

For text, I'd still use the smaller monitor. Given what I just said about reducing resolution of your display, text will appear smaller in native resolutions at 4k than it does in 1080p at the same font size and kerning.

Since your CPU doesn't support overclocking, unless you have plans to upgrade to an unlocked chip, getting a Z series board is unnecessary for overclocking. As such, no motherboard will offer a performance boost, assuming it supports your RAM speed, which\u2013based on the tier of the rest of the system\u2013I'm assuming isn't particularly high, and is likely supported by all motherboards.

From there I've basically just selected for price. You may be losing some I/O, and most of the cheaper boards only support 2 RAM modules (not a huge deal since your system only supports dual channel anyways, unless you have plans to upgrade your RAM), but it shouldn't really matter too much.

This is dependent on brand and design, so there's not a universal, fixed answer. On modern toner-based printers, the average is around 13% of the toner being wasted. Earlier or lousy models can go up to 25%. While it's technologically possible to route the wasted toner from the waste sump back to the print toner, this changes the chemical composition of the toner to have less fusible material, lowering the quality of the print. It is not in the interest of any printer company to overcome this issue, as the margin on toner is very high, as is demand.

Purely for future usability, I'm going to recommend you spend the extra bit and get a lower end quad core.

\n\n

Note that the performance of the rMBPs actually overlaps the standard MBPs, since they were released simultaneously with the same processors. Besides the upgraded screen and lighter weight\u2013things that seem to be unimportant to you\u2013the early rMBPs seem to offer little advantage, while carrying a price premium, having less I/O, and less upgradability. As such, I'm going to recommend you stay away from them.

\n\n

Depending on what model you get, you'll probably want to upgrade the RAM and storage to match your reference laptop. Both of these are user serviceable on the unibody MBPs, and can be easily serviced following the appropriate iFixit guide. If you're not using the optical drive, you can also swap it out for a secondary HDD or SSD. Note that there are some issues with SATA III compatibility to be aware of, but these are general non-issues if you're careful.

\n\n

Note that prices are approximate based on recent eBay sold listings. As with any complete system, finding a reasonable price on a used machine will take some patience and searching on various sites.

I am trying to set up some DIY home security video streams. I have several IP cams, like the D-Link night/day wireless Cloud Cam.

The problem is that it's hard to get a good angle and it's hard to deal with multiple video streams.

My idea is to leverage a tall (30'?) flagpole. If I could mount a camera to it at the right angle I could see my entire yard/perimeter from one camera. This is perfect since I want to be able to see where my dog is in the yard to know that she's OK.

Your motherboard manual, which you can find a link to here, has a layout map on page twelve.

\n

In the lower right hand corner of that map, there's a pair of pins that are labeled "CLR_CMOS". It is labeled by reference number 15. CMOS is the onboard memory storage for your motherboard, and is used to save BIOS settings. The CMOS memory can be cleared in two ways without booting the computer or accessing BIOS.

\n
    \n
  1. Follow the instructions on page 18 to short the pins and clear the CMOS memory:
  2. \n
\n
\n

Use this jumper to clear the BIOS configurations and reset the CMOS values to factory defaults. To clear the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.

\n

Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.

\n

After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).

\n
\n
    \n
  1. Pull the CMOS battery from the board for a few seconds before replacing it. This is located near the center of your motherboard, and is round like a watch battery. In the diagram on page 12 of your manual, you're looking for number 5 labeled as "BAT".
  2. \n
\n

After you successfully clear the CMOS memory, factory default settings should be restored and you should be able to boot the machine normally. Make sure to enter BIOS and re-configure any necessary settings before booting to your operating system.

\n

If that doesn't work, my next order of business in terms of recommendations would probably be to take your power supply into a local shop for testing. This is usually free but you can always call ahead to make sure.

Thunderbolt 3 offers this already using USB Power Delivery of up to 100W

\n
\n

Thunderbolt 3 was developed by Intel[48] and uses USB-C connectors. It is the first generation to support USB. Compared to Thunderbolt 2, Intel's Thunderbolt 3 controller (codenamed Alpine Ridge) doubles the bandwidth to 40 Gbit/s (5 GB/s), halves power consumption, and simultaneously drives two external 4K displays at 60 Hz (or a single external 4K display at 120 Hz, or a 5K display at 60 Hz when using Apple's implementation for the late-2016 MacBook Pros) instead of just the single display previous controllers can drive. The new controller supports PCIe 3.0 and other protocols, including DisplayPort 1.2 (allowing for 4K resolutions at 60 Hz).

\n

Thunderbolt 3 has limited power delivery capabilities on copper cables and no power delivery capability on optical cables. Using USB-C on copper cables, it can incorporate USB Power Delivery, allowing the ports to source or sink up to 100 watts of power. This eliminates the need for a separate power supply from some devices. Thunderbolt 3 allows backwards compatibility with the first two versions by the use of adapters or transitional cables.

\n
\n

However, your PC would obviously need a Thunderbolt connection.

\n

If your current PC has only DVI or HDMI outputs, as your post seems to suggest, then as neither of those offer sufficient power for a monitor, then your existing setup would not accommodate your request.

\n

HDMI 1.4a can supply power, but the port supplies only 50 \u00a0mA at 5\u00a0V DC over pin 18.

\n

Apart from Apple's 27" Thunderbolt capable monitor, which they have just discontinued (although you may be able to still pick up some discounted remaining stock), there aren't that many on the market. LG recently announced two models:

\n\n

From LG teases new Apple-compatible Thunderbolt 3 monitors including '5K UltraWide' model:

\n
\n

The 34WK95U is a 34-inch model with 5,120-by-2,160 resolution, high\ndynamic range, and LG's "Nano IPS" technology, which is said to boost\nthe "intensity and purity" of colors. Thunderbolt 3 lets the monitor\nhandle 5K images at 60 hertz, and connect laptops like the MacBook Pro\nwithout an additional power source.

\n

The 32UK950 will offer a similar featureset, but in a more\nconventional aspect ratio and with a slightly smaller 32-inch screen.\nThe display is said to hit 98 percent of the DCI-P3 color gamut, with\npeak brightness of 600 nits, and support a second 4K monitor through\ndaisy-chaining.

\n", "Title": "Which RAM should I prefer (CL vs PC)?", "Tags": "|laptop|memory|", "Answer": "

The \"PC\" number is a DDR module name, it indicates module's data rate.

\n\n\n\n

The 4 indicates that it's a DDR4 module. 17000 and 19200 are peak transfer rates. DDR4 data bus is 8 bytes wide, so 8 bytes are transmitted each clock cycle, hence multiplication by 8.

\n\n

Now, which is better: PC4-17000 with CL 15 or PC4-19200 with CL 17?

\n\n

CAS latency (or CL for short) is measured in clock cycles, so we can calculate how much time fetching data takes for each of these modules.

\n\n\n\n

So PC4-17000 has slightly better CAS latency.

\n\n

But! All RAM has to work with the same clock speed, so once you've installed 2133 MHz module, your current 2400 MHz module will underclock to 2133 MHz too.

\n\n

I'd probably go for 2400 MHz one. Latency difference is very small, but clock is 12.5% faster.

Although really it depends how much you care about size vs. cost vs. your own time, since you're not exactly trying to cram a lot of hardware in.

Off the shelf cases

\n

The thing about a case is that it's ultimately a matter of taste, and I can't decide that for you. With that, I'm going to provide a range of good cases and let you choose what you like. Most of this is copied from my previous answer here.

\n

Very small cases

\n

These cases are generally described as "artisan": made by specialized companies in low volumes, with extremely good build quality, at extremely high prices.

\n

Dr. Zaber Sentry

\n

$235 (TBD), 6.9L, 305mm video card, 5x2.5", SFX-L PSU

\n

\"\"

\n

It's the epitome of a very small case: extremely expensive, extremely tiny, extremely good build quality (primaily powder coated steel), pretty good compatibility with a few things to keep in mind, and runs a bit hot, but generally extremely good. One big issue though: you can't buy one. They're apparently targeting Q1 2018, but for now, I can't recommend what you can't buy.

\n

NFC Skyreach 4 MINI

\n

$199, 5.0L, 215mm video card, 2x2.5", special

\n

It's the smallest case in this category. Note that video card compatibility is very limited, drive mounting is limited, and most of all, PSU compatibility is virtually nil, with only two PSUs listed (a $95 400W DC-DC and a $58 200W DC-DC); however, these should be non-issues for you.

\n

You like shoeboxes? I like shoeboxes! Made under contract by Lian-Li of mostly aluminum, it's (IMO) the prettiest case on this list. But again, it's not for sale yet (just preorders), and I can't recommend what you can't buy.

\n

Pretty small cases

\n

These cases are a step up in size from the very small cases, and benefits to match. These are largely cheaper, easier to work with, have better support, and are actually available to purchase!

\n

NCASE M1

\n

$195, 12.6L, 317mm video card, 3x3.5" + 3x2.5", ATX (SFX-L highly recommended)\n\"\"

\n

The sort of "daddy" of small cases, the NCASE M1 is the last artisan case on this list, and one of the older ones here. It has incredible support for hardware (even a slimline optical drive!), while being spacious enough to keep things from getting too toasty.

\n

Fractal Design Node 202

\n

$80 or $130 with a 450W PSU, 10.2L, 310mm video card, 2x2.5", SFX-L\n\"\"\nIt's an extremely popular choice, and a good one! Nothing stands out really except for the very reasonable price.

\n

$85 to $130, 14L, 330mm video card, 1x3.5" + 2-4x2.5", SFX-L

\n

Silverstone ML08

\n

$70, 12L, 330mm video card, 2x2.5", SFX-L

\n

\"\"

\n

It's literally based on the RVZ02, but smaller, cheaper, less drive mounting, and with an optional handle!

\n

Honorable mention

\n

The Silverstone SG05 and Silverstone SG06 are neat too, but much boxier. The Fractal Design Array R2, Lian-Li Q09, Raidmax Element, SilverStone SG07 and SG08, and Xigmatek Eris EN6305 are no longer in production, though they would make perfectly good boxes if you can find them.

\n

Not as small cases

\n

They're bigger with support for more things! They're also much quieter. Carrying handles are a must here, since you said that regular transport was an integral part to this build. These cases seem to have largely fallen out of favor as smaller cases take over the mITX sector, but I've put them here anyways.

\n

BitFenix Prodigy

\n

$60, 26.4L, 317mm video card, 5x3.5", ATX

\n

\"\"

\n

HardwareCanucks put it best: It's a beautiful chassis at a great price with a few minor compromises for that goal.

\n

Honorable mentions

\n

The Corsair 380T is a great case, but unfortunately, it no longer appears to be in production, and second hand prices for it are absurd. The Silverstone CS01B is also rather neat, but the 190mm max video card length kills any recommendation. The Cougar QBX and Fractal Design Define Nano S are beautiful and compact, but too large to not have a carrying handle and still be intended as portable IMO.

\n

Your own case

\n

The great thing about building a PC is that you're free to use whatever components you'd like, including building your own! Because you're not trying to cram a lot of hardware in, if you're really bent on getting the smallest case possible, it might be worth looking at rolling your own. The off-the-shelf cases are created with the intention of being used with more "normal" motherboards and usually have to accommodate a PSU and GPU\u2013things that aren't issues in your case. mITX is an open standard, and it doesn't take much to make a basic case.

Switch emulation isn't quite a thing yet, but Nintendo has always been pretty emulation-friendly as far as minimum requirements.

Your target software is probably the Dolphin emulator, since it covers a breadth of Nintendo emulators. NES, GB, GBC, and SNES (including SGB adaptation) are simple emulation on any modern machine, and it won't really matter what you have.

When you get into the GC, Wii, and Wii-U, you're going to need more RAM. An i7 or higher-end AMD processor wouldn't be a bad idea, either. Emulating these systems is significantly more demanding and usually has hooks that make use of your hardware a bit more instead of just isolated emulation. I got almost flawless performance in all games up through the GC and some Wii games on an i7-2600k with 16GB of RAM and a GTX 760, so your hardware picks should still be fine.

\n\n

Seeing as you can get an i7 for not much more than an i5 these days, I'd definitely go that route.

I think your problem is probably more price range than anything else. The touchscreen monitor is the expense, and takes up a large portion of your budget. For instance, this one takes up half your budget, and it's an inexpensive option by your requirements. Another one takes up much more.

Windows 8 - 10 has the ability to run as a Kiosk, and you can find some tutorials to teach you how to set it up that way. This will handle your worries about user access.

You may wish to consider the less expensive option of using QR Codes. QR codes next to your product allows anyone with a smartphone that can read a barcode (which is pretty much all of them) to auto-link to a website of your choosing. Ideally, this is your website that has been programmed, made adaptive to mobile, and hosted for you, to which your in-store screens would probably have been pointing, anyway. This gives you less to maintain, less up-front expense, and when bored children start playing with screens, it will be their own screens or those of their parents and not your expensive product terminals.

I am a bit lost on what adapters and cables I need for connecting a second external monitor to my laptops.

\n\n

I already have an external HDMI monitor. All my three laptops have HDMI ports with which I am able to use this external monitor (using HDMI male-to-male cable). I want to connect one more HDMI monitor now as a second external display (ideally to any of my three laptops). All three laptops run Windows 10.

\n\n

All three laptops have multiple USB 3.0 (SS) ports. They all have mini display ports (I believe I am using the correct term) as well, but one of them seems to have a different kind. Please see images below.

\n\n

Laptop 1:\n\"Laptop\nThe port on the left above is what I think is the mini display port.

\n\n

Laptop 2:\n\"Laptop\nThis laptop has the same kind of display port as laptop 1.

\n\n

Laptop 3:\n\"Laptop

\n\n

I am not sure if the left most port in this image is the same as the left most ports in above two. It doesn't have the two + symbols like the ones above have. Is it the same as the ports in the first two laptops?

\n\n

Not realizing that I have these mini display ports, I purchased \"Plugable USB 3.0 to DisplayPort 4K UHD\" from Amazon (for $60), which has a male USB 3.0 and a female full-sized Display port. I believe that I now need a display port to HDMI adapter to connect to the external monitor. Would it be better to return this adapter and purchase a different one?

\n\n
\n\n

UPDATE: I don't really need HDMI for my second external monitor, since it also has a VGA port. I ended up purchasing a USB 3.0 to VGA adapter, which costs only $16. All my laptops have at least one spare SS port, so I am good now.

Get a passive Mini DisplayPort to HDMI cable, like this one

\n\n

As SiXandSeven8ths mentioned, DisplayPort++ (also known as Dual Mode) is a technology that allows DisplayPort to put out another signal for use with passive adapters. While limited because of this unidirectionality, it's an incredibly cheap, easy, and effective solution for what you're trying to do. Though it's difficult to confirm with your third laptop, almost all laptops with Mini DisplayPort support this mode because of its extreme popularity and utility\u2013even when not indicated, like on the XPS 13.

\n\n

\n\n

One thing worth noting is the Thunderbolt 3 connection on your third laptop. Thunderbolt 3 (and USB-C, which can also carry a DisplayPort connection) cannot utilize DisplayPort++ because it lacks the necessary pin count to do so.

While your solution of using a USB to VGA graphics adapter works, I would advise against this in the future. VGA is a much more limited connection, namely in that it is an analog rather than a digital signal.

Can someone recommend a monitor that can play video files straight from an external hard drive, preferably along a USB to USB connection and preferably in various formats (certainly including .mp4, preferably also .flv and .mkv), and that does not need also to be connected to the internet or a laptop or use wifi. Ideally I would like something that does not receive any kind of TV signal and therefore does not require a TV licence to keep.

To summarise: I need a screen that I can put on the wall so that when I want to watch one of the films I've got on an external drive, I can throw a USB cable from the external drive to the monitor, throw an audio cable from the monitor to some speakers, and sit back and watch the film.

I am looking for a small mobile device to display a list of sensitive information.

\n\n

The storage of the device must be encryptable and the user must first enter a PIN to decrypt the storage at boot time and second enter a PIN to authenticate himself in order to use the device.

\n\n

The size of the device can be up to common tablet size (~10,5''), but the smaller the better.

\n\n

Moreover, the device must own no wireless interfaces to reduce the possible attack surface. As a consequence it is only possible to I/O with the device via a wired interface (which should be a common type, e.g. USB).

\n\n

For the usage, the device should provide a touch screen, but this is not mandatory. Another kind of user interface interaction would also be ok.

Most likely this is because the WIFI system is not found or some related consequences caused by removing WIFI and BT from the build.

I built a PC not very long ago. Here are the specs (I have a different case, but I couldn't find the one I own, so I chose a similar one). My 1050Ti is a really good graphics card.

Other than that, if you really cannot wait or think you want to spend the money on the next generation, I would keep a hawk eye out for a 1080 Ti.

1080 Ti would be future proof for you. It will do 60 FPS with all setting on high and 1080P and you can even get 45-60 FPS with most setting high at 4K if you ever go there.

The real question is:

\n\n

What do you need it for?

CPU

\n\n

I wouldn't really care about the processor, as long as you don't do anything requiring an intensive processing power.

\n\n

You can find a lot of cpu comparing sites by searching on any search engine \"cpu compare\" or \"cpu benchmark\".

\n\n

Storage

\n\n

The SSD will gargantuanly benefit the performance. The computer will start faster, the programs will start faster, everything will be faster. But with 250GB you may not have enough space, depending on what you do. Do you store photos, videos and bigger files on your computer or do you use cloud services? If you don't, with time you may run out of space without an external hard disk. Meanwhile, the 1TB hard disk will give you a lot of space.

\n\n

Also, could you post the specific model of processors in your post? I don't yet have enough reputation to comment.

\n\n

Edit:

\n\n

I've used this website and Intel's official catalogue of products for a comparison, take a look as they are very helpful.

\n\n

The main difference between the 2 is the number of cores. The 7th generation one got 2 cores while the 8th generation one got 4 (I'm talking about physical cores, not thread or \"virtual\" cores). Remember that they are both low-end cores, so you may have problems calculating, as you said in the comments, macros or data in number of millions, with both of the computers. Still on a Windows environment an SSD will be a greater advantage compared to a slower-quad core processor, as Windows is very resource demanding when talking about hard disks speeds (I'm looking at you Cortana).

A \"safe\"/green network for devices I trust (my computers, game consoles) that will be a combination of wired and wireless, a home automation network where the assistants and automation hardware will live that will need a single wired port and the rest will be wireless, a DMZ where the servers will live that will be all wired access and a guest wireless network that will be all wireless access.

Having had a very similar use-case, I highly recommend Ubiquiti EdgeMax Routers for managing your network. They are high quality options (with some nice security and resource delegation features) and have many models that support Power Over Ethernet on at least one port. They also work well when establishing the kind of subnets you are talking about. I've used one in combination with my modem to form a gateway for quite some time. Just a couple of $60 models to separate the concerns of managing the two different networks (so that a problem with one doesn't mean a problem with the other) and to allow isolation of the network you don't want reachable by guests would do the trick. This also gives the option of setting up two subnets for your networks if you get three routers, all for under $200 together. They're also usually about the size of a cell phone.

\n\n

I was running this through a mid-range Asus router, but it failed as an AP unless I also allowed it to run its own subnet and function as a router. Even then, reliability was sketchy. I recently replaced it with an Ubiquiti AP-Pro, which supports both bands under one network ID. It has its own software for managing access and has an option for activation and management of a guest network with restrictions as to what guests may do. The unit is weather-resistant and is designed to be wall- or ceiling-mounted if you like, so it's possible to even mount them externally. It also has a second ethernet port for bridging or connecting a computer directly to the wired connection, making it easy to chain multiple across a house instead of setting up a mesh network or configuring the device to repeat a signal and lose bandwidth. I currently use only one of these on my second floor of my 5000 sq ft home; a direct connected device consistently gets nearly 1Gb/s speeds on the internet (which is max 1Gb/s), a wireless-AC connection one floor down usually gets 500Mb/s minimum, and my son's connection across the house never drops below 200Mb/s. The unit cost me about $90 as it connects to the PoE on the router for power, but you can get an injector for about $20 if you need to supply power another way.

\n\n

3x Ubiquiti EdgeMax = $180 (because this gets you DHCP 3x and separates your APs entirely based on network)

\n\n

3x Ubiquiti AC-Pro = $270-340 (depending on power connection and presuming you need more than one due to geography)

\n\n

4x Decent wall Surge Suppressor (if you hook up your units with PoE Injectors instead of normal PoE) = $80

\n\n

Huge spool of Cat5e (6 is a waste for 1Gb and down) = $80

Crimping Tool = $30 (because crimping your own cables is infinitely cheaper in the long haul)

I currently have a 5 year old HP laptop running Windows 7. I live in a rural area where our internet speeds are 1 MB or less. I am actually able to do skype calls and online video chats with people online even with my poor internet connection (it is very low quality but it works).

\n\n

Windows 7 is starting to get a bit old and I was thinking that it was time to get a new laptop. The first laptop that I got was a HP Stream 15 or 14 inch screen with 4 GB of RAM. I know that it is not a powerful computer, but I mostly just browse the web and use skype. Unfortunately, Windows 10 has such large updates that 100% of my internet connection is always consumed by updates. My DSL modem is running/sending traffic continually. At times, it is very difficult to even get it to load google. The HP Stream has behaved like this even when it was new - so it doesn't have a virus and I installed a virus checker and did a scan to verify that it has no viruses. My Windows 7 laptop does not consume large amounts of bandwidth like the HP Stream. I also tried setting my wifi connection to be metered, but it still consumes all of my available internet bandwidth.

\n\n

The next device that I tried was an Acer Chromebook. I know that skype doesn't run natively on chromebooks, but I found some online browser based video chat websites and tried using one of these (there is also an online version of skype). However, about 10 minutes into the chat, the entire labtop's screen goes black and it crashes.

\n\n

So I've now tried both Windows 10 and Chromebooks. Windows 10 would be fine if it could download multi-gigabyte updates (I've even left my HP Stream on overnight in hopes that it would download the updates, but it is still not done in the morning). Chromebooks would be fine if they didn't crash.

If you are lucky you may notice that updates get smaller with newer operating systems like Chrome OS, Windows 10 or Fedora which should be able to use delta compression and only download the new bits. At least Fedora should be able to do that with DeltaRPMs which it uses by default. I don't know how it plays out for flatpak updates or Silverblue though.

I have checked a few questions here regarding the GPU and bought the 1080Ti.\nNow I am trying to figure out the rest of the configuration and it should be below 1000$.

\n\n

I have seen that i5-8600K sounds like a good option and I would like to go with 8th generation. However, now I am stuck with choosing the appropriate motherboard and cooling units.

\n\n

In my country I have available:\nGIGABYTE Z370 AORUS GAMING 3 REV.1.0 and ASUS ROG STRIX Z370-H GAMING which i have available for 230$ and 280$ respectively.

I am also considering Gigabyte Z370 HD3 which is a cheaper option 150$.

You should go with the Gigabyte Z370 HD3, since it is the cheapest option meeting your requirements. However, if your configuration requires a lot of RAM which you didn't mention, the most expensive option (ASUS configuration) offers 4 slots of RAM. According to the intel spec sheet for the i5-8600k, the maximum supported memory per slot is 32 gb. It's up to you whether you feel you will need more than 32gb of RAM in the future.

It's worth mentioning the GIGABYTE option has 2 m.2 SATA slots meaning you could potentially have two m.2 sata SSDs (The Samsung 970 Evo's are an affordable high performance option.)

I don't know if this is a weird question, but here it goes: I would like a laptop without a GUI. I want to exclusively use the command line. I want to install Linux in it. The laptop should be small, 14\" tops. It should have an excellent battery life, and good wifi. Hopefully, the hardware will be supported natively, without binary blobs.

I am using EVGA - SuperNOVA G2 850W 80+ Gold Certified Fully-Modular ATX Power Supply for my current build, and my load seems to be 470W. For my computer monitors, I am using Lenovo LT2452P. So, I need one power cord for PC and one for the monitor.

\n\n

  1. I am trying to determine between 18/16/14 AWG which power supplies do I need for my PC and my monitor.

\n", "Title": "Recommended AWG for my power cord", "Tags": "|pc|monitors|power-supply|", "Answer": "

If your load is 470W, then even at 110V (worst-case scenario), you are using 4.3A. According to the AutoZone guide, even at the thinnest (18AWG) wire, you can run 13 Amps through it (which is >3 times what you are using), and having it heat only to 150\u00b0F. Therefore, you can run the 18AWG wire without any problems.

\n\n

In general, when asking this, you should include the length of the power cable, and the temperature you'll use it in -- as it makes a huge difference. For example, I had a 24AWG cable that could handle ~150A at below freezing, which is ~35 times as much as your scenario -- precisely because it is only a couple inches long. One time I used it at above a freezing temperature, and it melted the isolation off of it.

(Yes, I\u2019ve seen this question which is very similar, however my specs include the word gigabit. Also the only current answer to that question was written by someone that didn\u2019t understand the meaning of \u201cdual-WAN\u201d and made an incorrect assumption about its meaning.)

\n\n

I\u2019m looking for a gigabit multi-WAN (or dual-WAN) Router for use in an automatic failover application. I have a problematic cable connection which fails several times a month. With my current level of home automation I can simply no longer accept that failure.

\n\n

The cable modem is already a separate device (i.e. not an all-in-one combo device). I have also already purchased a Netgear LB2120 4G cellular modem, which was supposed to also handle the failover routing (oddly the cable company blocks the device as a failover router, I can use it as a modem behind another router tho). LB2120 also has no means of external configuration. At the moment switching internet connections is as manual as walking in and swapping plugs, which doesn\u2019t work if I\u2019m not home.

\n\n

I\u2019ve also already tried purchasing, and recently returned to vendor, TP-Link TL-ER5120 v3 which should have solved the problem, but doesn\u2019t because it has an odd firmware bug which seems to block ports on the local network. (Specifically in testing port 3389\u2013I suspect many others). There is a bizarre long email chain with TP-link support where the initial entry level support associate validates my claim \u201cin the lab\u201d. She passes the case to \u201csenior level support\u201d who consistently argues there is no problem found, and continues \u201ccoaching\u201d me on setup. There are several really odd things that make me suspect about the \u201csenior\u201d techs understanding of his job, he insists: Static IP (not DHCP reservation) must be used, he also insists the client end (not the server end) be assigned the static IP, and finally he admits he is not using 5120 v3 but an older 6120 model that is \u201cvery similar\u201d to mine. He consistently tells me I don\u2019t understand what to do, that I\u2019m not following his instructions (even though I tried it his way and sent screenshots proving that I did). There is also now another user in the TP-link public forum same complaint

\n\n

Requirements include:

\n\n\n\n

So to further reiterate, this router must have the ability to handle at least two internet (WAN) connections, one primary and one failover.

\n\n

Edit 2020-05-30: (this question has gotten a lot of attention just lately). As indicated in the comments to the marked answer, two year ago I purchased the Ubiquiti ER-X. I was very happy with the choice, however 2 years later, I\u2019ve just recently upgraded to the ER-12. The three elements that factored into the upgrade. 1) primary internet was upgraded to 1000Mbps (the ER-X didn\u2019t perform well, even with hwnat enabled). 2) the router was running a VPN which was rarely used but slow for streaming video 3) the added hardwire ethernet jacks allowed me to eliminate a switch.

Another option is to roll your own.

\n\n

Inspired by a series of articles by Jim Salter on Ars Technica about building a Homebrew router, we moved routing functionality of our network onto our application server and it has been working well.

\n\n

Hardware

\n\n

The server itself is Dell R220 (shallow 1U) with a four Ethernet ports. Our main network is plugged into one port, our DSL modem into another, and our cable modem into another, leaving us a spare port for network link aggregation later if necessary. We even have a DMZ machine for one of the modems attached via a VLAN.

\n\n

The server cost us less than $150 including shipping and is obviously old, but serviceable server grade kit with ECC memory rather than a built-to-a-price-point mini PC with restricted CPU performance (and power consumption). Any free server on your network with enough Ethernet ports may be suitable instead though.

\n\n

Software

\n\n

We run Proxmox as the host operating system (ZFS root pool for the win), then run OPNsense in a virtual machine as our router, with the modem Ethernet ports & DMZ VLAN only being accessible from within the VM.

\n\n

We also run all of our Docker instances on this machine, so it would be powered on 24/7 anyway, and the extra load of the router VM is relatively small, even when maxing out internet use.

\n\n
\n\n

This solution is one I would consider for any network that is any more complex than a simple one-line one-modem/router combination.

This option explicitly supports 64 GB of RAM. Most mobile systems don't really support 64 GB RAM upgrades because there isn't really a market for gratuitously expansive memory in laptops, as most people would purchase a non-mobile desktop/server system for the average user case scenario (hosting, servers, etc.). If you are thinking about 64 GB of RAM in the future, I would advise explicitly buying a 64 GB supported laptop out of the box as it is likely most laptops will only have 2 slots for memory meaning an upgrade will be a full replacement, as you won't be able to add to your existing memory infrastructure. Effectively, you will need to buy 2 32 GB memory sticks which will cost you in the ballpark of 1793.59 - 3587.18 kr. If you try and skimp on RAM costs, it is also likely you will buy poor latency (Higher CAS latency values) RAM, which will have inferior timings and therefore more delay.

The only way to find out if the operating system you want will work on that hardware is to try it out. I'm guessing that the reason you're asking this question in the first place is because you want to save money on hardware and this server you found (used, maybe?) looks too good to be true. As with most things in life, it probably is.

\n\n

The main issues that I can think of with this kind of hardware are power draw, noise, and graphics. Even if it seems like you're getting a great deal, you might end up spending more money in electrical bills over the course of the time you own the server than you would if you just bought a new, energy-efficient desktop. Additionally, the cooling for server-oriented machines is designed to get maximum airflow and dissipate the most heat, without any regards for noise level. If you use the machine near where you're working with it (as with most desktop deployments), you probably won't like how loud it will be. Finally, if you think about how most server-class machines are used, graphics is not too important. Most servers run headless (without a monitor) and so do no graphics whatsoever. If you can stand the other two annoyances, the lack of modern-ish graphics might be a deal-breaker if you intend to run a graphics-intensive operating system like Windows.

I have just had my third desktop PC in four years fried by an apparent power surge during a thunderstorm. We rent an ancient house in Western North Carolina (read: \"awful Duke Energy electrical grid and wiring that was installed shortly after Ben Franklin went kite-flying\"), so I can't fix any of that.

\n\n

Four years ago, there was a (probably) lightning-generated surge that took out a (turned off) desktop PC, my beloved gaming rig, one monitor, the ISP's modem, my Linksys router and an electric blanket.

\n\n

Yesterday, another lightning-generated surge took out my (turned off but plugged in) gaming rig and, weirdly, whatever gizmo there is in the ISP's Arris router that handles ethernet connections - its wifi still works.

\n\n

Neither of these surges damaged anything else and they didn't knock out the power or blow a breaker.

\n\n

Is there a surge suppressor that can protect electronics from this kind of thing? The fellow from the ISP that replaced the modem four years ago told me that nothing can contain a surge like that and that the only sure way to protect my gear is to unplug it during electrical storms. Is he right?

\n", "Title": "I really need to find a surge suppressor that works!", "Tags": "|power-supply|", "Answer": "

Lightning is a hard problem.

\n\n

I'd love to say there's a slick little product you can \"Amazon and it's done\", but not all problems can be solved that way (plus, other answerers are already doing that.) That said, I promise there'll be some products mentioned.

\n\n

On the high side of the transformer: Transformers are pretty good surge suppressors, so suppressing surges on the \"high\" side of the transformer helps a lot. Power distribution lines (the big 2400V lines that are the top row) have a couple defenses. First, a \"top wire\" (OHGW) that is set above the 3 bare conductors - its job is to catch the lightning bolt instead of the conductors. Second, a lightning arrestor device connecting each conductor to ground. It has an engineered gap - wide enough to stop 2400V from arcing to ground, but still allow lightning to leap to ground. These can wear out/burn up from strikes, and leave too-wide a gap to be effective. You can't do anything about this stuff. But you can walk your neighborhood distribution lines (on the high side of your transformer) and see if Duke has installed them, and shout a lot if they haven't.

\n\n

Make sure your house's grounding/earthing is tip-top. I realize you're a renter and can't do this. But correct, modern grounding is an absolute requirement for some surge suppression systems to work, and certainly to qualify for any \"power strip warranties\". Surge suppressors need ground as a place to dump the surges! All electricity wants to return to source, and natural electricity's (lightning) source is the earth. If you can't make your house's grounding tip-top, don't bother with surge suppressing power strips or whole-house suppressors. They won't work.

\n\n

\"enter

\n\n

Make sure comms entrances are also grounded. Code requires that your cable TV, phone/DSL etc. lines go through a lightning arrestor on the outside of the house. These arrestors need to be very well grounded, ideally just a few feet away from a ground rod (better: two) going into the earth. A renter might be able to pester the ISP to fit quality surge suppressors on cable/phone. However, if the ground wire is thin, and has to be carried some long distance to get to the ground rod, it's almost a waste of time.

\n\n

Defend against neutral problems. Problems with neutral can cause voltages that should be 120V to fluctuate wildly between 0 and 240V. However this is easily handled by auto-ranging switching power supplies - the kind rated to function on a range of voltage such as 100-264V or 90-306V. They autorange on the fly, and when they get a spike that's below 264V, they just treat it like more usable power. Many products are already this; just make sure yours are.

\n\n

\"enter

\n\n

A whole-house surge suppressor. Again a renter can't install this. Siemens, Eaton etc. are big players in industrial power distribution. They make whole-house surge suppressors. These are hardwired right into the service panel. In some cases they tap the mains, otherwise you hang them off a 60A breaker.

\n\n

If you were hardcore, I suppose you could buy a large metal electrical box, put a cord and strain relief on it, and a whole-house surge suppressor and some sockets. Voil\u00e0, the world's biggest baddest surge suppressing power strip.

\n\n

\"enter

\n\n

Air-gap your connectivity. Lightning can't leap across WiFi. If there's any way to WiFi your connectivity, do it. If you feel you can't, then make sure your demarcation point surge suppression is tip-top, and maybe add some in-house surge suppression too. (but this is pointless if your grounds are rubbish.)

\n\n

Buy quality power supplies. Since it sounds like you build your gaming rig, don't treat the power supply like an afterthought or buy one for the flashy lights. Buy the best. Server tier power supplies are not excessive at all. A good power supply can take a lot of hits, because that's its job. VESA isn't famous for taking surges. Buy ones that are.

An isolation transformer. Here's something a tenant can do! However these things are massive with an iron core and copper windings. Transformers (like the one on your neighborhood's utility pole) are huge inductors tuned to one frequency: 50 or 60 Hz depending which continent you are on. Like any large inductor, they only like to pass 50/60Hz, so they tend to block spikes and surges. If you have any other lightning arresting in place, that should keep spike voltage low enough that it won't leap the transformer's insulation. Place your equipment on the isolated side of the transformer, and it should see almost no external noise.

\n\n

I am reluctant to say \"ground the isolated side of the power supply\" if your house's grounds aren't very good. It may be better to leave it an isolated system, except then you'll end up with an islanded ground. I'd fix that with GFCI. Every piece of interconnected equipment needs to be on the isolation, except for modems and routers - otherwise the connecting cords will simply carry the spike around the isolation transformer.

\n\n

Acquiring an isolation transformer can be tricky. First, it's not a step-up/down transformer. You can just up-n-buy one from Amazon, but the price may hurt. I see \"5 KVA\" service transformers all the time on Craigslist for $100 or so, and those'll work just fine as an isolation transformer with an excess of capacity -- but you'll need a 240V power source and some help from an electrician to set it up. In that case I would probably get a small rack and set it up like a PDU. Craigslist sometimes sees 1.5 KVA transformers that are much lighter weight.

\n\n

You need an isolation transformer of appropriate size (look on your equipment's nameplate for its rating in VA [similar to watts but not quite the same], otherwise multiply amps by your line voltage: 120 or 230V). Expect cheap gaming rigs to have numbers in the 1200 VA range (yes I know the power supply says \"850W\"!) If you can measure actual peak draw with a Kill-a-Watt, you can go with that number instead.

Comparing my options on Amazon, I think my priorities are (in order):

\n\n\n\n

Am I likely to actually experience significantly better performance with more RAM?

\n\n

For comparison, here are two Chromebooks with dramatically different sticker prices (obviously for more reasons than just RAM):

\n\n

Acer with 4GB RAM

\n", "Title": "What benefit would I see with more than 4GB RAM in a Chromebook?", "Tags": "|laptop|memory|chromebook|", "Answer": "

I want to mention that there are also models with 8GB of RAM and more options to choose from in the price range between $350 to $1500.

I am in the market for a Chromebook. This will be a second machine, like a Kindle Fire with a keyboard. I'm not imagining any kind of power use at all, just streaming, reading, word processing, surfing, and monitoring of videos and photos as I shoot them. But that's not to say that I couldn't discover that I like using it for other things too.

\n
\n\n

Kindle Fire with keyboard, that pretty much is how I use my Asus C302 and I also think of it as: \u00bbnah, it's not running anything fancy.\u00ab But actually it can amount to quite a lot and there is not much left of 4GB RAM even though I usually use it with GalliumOS and Firefox which is a bit more aggressive with memory management (you should stick with Chrome OS though!).

\n\n

Edit: on second thought, I cannot imagine making good use of more than 8GB with your usage patterns at the moment. I had a laptop with 16GB for two years, not used for gaming or hosting more than one virtual machine, RAM was just rather cheap at that time.

\n\n
\n\n

From the point of view that a Chromebook is a piece of computer hardware with a keyboard and a 10-15 inch screen that runs a webbrowser to display websites it may look like 4GB are sufficient. At the moment.

\n\n

The best way to find out if 4GB is enough for you would be open Chrome's Taskmanager during your usual desktop browsing and check how much Chrome consumes. Some extensions also consume additional RAM, websites tend to grow and be designed more responsive, also people usually have several tabs open or pinned. 4GB is okay for now but on top of my head knowing the browsing habits of people around me and my own and that a Chromebook may well last 5 years or more while being regularly updated with security updates and new features(!), I'd recommend to spend a bit more money to get an 8GB model at least.

\n\n

From another point of view I have watched 2GB Chromebooks and HDMi sticks suffer under the load of poorly written iframe Grafana & Kibana madness for months. You don't want to run out of RAM if it can be avoided.

\n\n

Chromebooks also feature Android Apps and Linux apps (Crostini). It is still not a full fledged desktop experience like a Mac or Windows computer but you certainly have the possibility to make use of more than 4GB RAM now or in the future. Some people may argue that you could close some rather unimportant tabs or that the browser should manage background tabs better but I don't think that is a good solution as you may want to use a split view to view more pages at the same time, work with multiple monitors (small portable monitors exist) or just have the information ready when you need it (and no network access).

\n\n

The benefit is to not run out of RAM, which results in significant system slow downs. Also typically RAM cannot be upgraded on Chromebooks. I'd give the same advice for Chromebooks as I'd give for any laptop that you are going to use the next couple of years: 4GB RAM is not enough, get 8GB and have peace of mind.

\n\n
\n\n

Edit 2018-09-12: There is another point to consider: the processor.

\n\n

To keep it simple: try to avoid Intel processors where the model number starts with an N.

\n\n

These are out-of-order low power CPU designs and different from typical mobile CPUs. They have been marketed as Atoms but also as Celerons and Pentiums. If you can afford to spend more money get a device with at least a Pentium processor without an N in the model number, or even better an m3/i3 or m5/i5. Intel has been very liberal with names and letters which is very confusing for consumers after some generations/years.

\n\n

Google is likely going to present a successor to the Pixelbook in a few weeks. Keep your eyes open you may find a good deal for the old model. If that's not an option you can check reddit where a user posts a Bi-Weekly Buying Advice Thread, here is the latest one at the time of writing: https://www.reddit.com/r/chromeos/comments/9ci9bd/biweekly_buying_advice_thread_sep_2_15/

\n\n

I live in Germany where Chromebooks are rather unpopular, so there isn't much advice I can give where to get the best deal in your region.

\n\n

Final note: I also do have a Lenovo N22 with said Celeron N processor, It gets work done (it's the one I tortured with iframes) it's just not that kind of device you were initially looking for, a convertible for a bit more than $500 and 8GB should be a good choice for the next 5 years.

I'm trying to build a device made up of several other devices all connected using USB A cables. The amount of room on the cables taken up by the \"human sized\" ends requires a larger enclosure than I want to use. Other than purchasing raw USB connectors and soldering them myself, where can I purchase cables with minimal ends?

\n", "Title": "Where to purchase USB cables without \"human sized\" ends", "Tags": "|usb|cable|", "Answer": "

One option you have would be to use a straight circuit board with appropriate traces, if the minimalistic approach is your objective. I have what is described on Gearbest as a USB flashlight:

\n\n

\"USB

It is a 1.92 mm thick piece of circuit board that fits well into the USB port of my powerbank. The price for five is US$1.13 from gearbest. This is one example.

\n\n

Additional searching has discovered a link to a site called eLabBay which sells prototype boards that are a bit more bulky than the USB flashlight:

\n\n

\"prototype

\n\n

You would be able to ignore the header pins and cut away the wings to further reduce the profile, if needed. At bit more expensive at US$6.48, but it's also just another example.

\n\n

There are circuit board services which will produce boards from your design. In larger quantities, I'd expect the prices would be better than this last one, but requires that you create a design. I did a quick search for \"pcb service\" and the first return showed ten pieces for five dollars and that was only one entry. There may be others at lower prices.

\n\n

Of course, all of this does require that you perform the soldering, but it's not as finicky as doing so with typically stock small gauge USB wire.

I have a set of bluetooth earbuds and I have been using them with my MacBook running High Sierra. I use them for Slack calls and the quality basically sounds like I'm talking on my phone.

Analysis/Justifications

\n\n

GPU Choice

\n\n

Foremost, typically the most expensive part of a high-end custom build tends to be its GPU, where the latest 1080 and 1070 GPUs cost about your entire budget alone. In order to reduce cost I decided to recommend you a GTX 1050 which should be able to render 4K at 60 fps, I don't believe the C++ OpenCV libraries are terribly inefficient so you should be good there.

\n\n

CPU Choice

\n\n

The i5-8400 is on par with the i7-6700K in terms of performance with the exception of floating point calculations where it lags behind a little bit.

\n\n

SSD Choice

\n\n

The PM 961 outperforms the 2.5\" Samsung 860 EVO with a whopping 1496 MB/s seq read and 722 MB/s seq write. If you're not familiar with them, the Samsung EVO's are well known for being one the best valued SSDs and can pack quite a punch. I have an 840 EVO and can attest to its performance.

\n\n

RAM Choice

\n\n

I had to skimp on the RAM to try and save money. I did however try to find RAM with the lowest CAS latency.

\n\n

Build Caveats

\n\n

In order to save money on the Motherboard, I had to use a motherboard that only supports up to 32 GB of RAM despite the i5-8400 supporting up to 64 GB of RAM split over 2 slots. Also the cheap-o case I recommended doesn't have front panel USB 3.0 ports.

\n", "Title": "Is i7-3770k really worth buying than i5-3570k?", "Tags": "|processor|", "Answer": "

When it comes to comparing CPUs in an objective way without having them on hand, the quickest way to estimate how a processor will perform, and therefore, its value you is to look at benchmarks between the processors. Here, we can see the effective speed is pretty negligible, but the average user benchmark for multi core scenarios is markedly faster.

\n\n
\n

I mean it is not a real core right?

\n
\n\n

Well, it depends on what you define as a \"real core\". Take a look at Intel's article on its Hyper Threading technology for a sense of the mechanics behind the theoretical cores.

\n\n

In terms of \"is it a real core\" in a \"does it do anything?\" sense, the 4 theoretical cores does make a measurable impact as the i7 has a faster Multi Core Integer and Floating Point calculation speed by about 33% and a bench marked multi core speed of +39%.

\n\n
\n

Are the extra 4 threads really worth paying double the price?

\n
\n\n

The four extra cores on the i7 are \"theoretical\" or hyper thread cores.

\n\n

Whether it is worth it, really depends on your user case scenario. Something like video encoding may benefit more from the increased multi-thread speed, while a badly written single threaded game might not see as much benefit.

\n\n

My guess is if this computer is going to be for general use, you could probably get away with the i5. Computer enthusiasts making gaming builds typically downgrade to i5 variants of their i7 processor when their budget demands it, as it is usually better to reallocate those resources for a higher end GPU.

I need a keyboard which has an extra key in the area of the left thumb.\nI need this extra key to bind it to the mouse left button, because I use graphic tablet a lot and it's next to impossible to work normally without a mouse click functionality. Currently I use Autohotkey and bind the LWin key to emulate the mouse click, but it is inconvenient\nbecause the LWin key is in the 'dead' zone and I need to make extra movements all the time so it is quite painful.

\n

So I need a keyboard which has some extra key in the thumb area i.e. where the space bar normally is. The problem though - none of the standard keyboards have them (they only have a huge spacebar as everybody knows).

\n

I've spent a lot of time googling and I have found something that looks promising:

\n

\"enter

\n

source: http://mc.pp.se/dc/kbd.html

\n

It's a Japanese keyboard. This seems exactly what I am looking for, because there are extra buttons on the bottom row. All Japanese have them so I could buy one, BUT: the problem is, I am not sure how this extra key (left to the spacebar) will act normally if I use Windows and e.g. standard US layout? Will it be possible to make use of it by binding it to the mouse click with Autohotkey? Or maybe there are some Japanese keyboards produced for EU/US market with those keys as a bonus (would be ideal)?

\n

Also I have found another possible solution: ThinkPad Lenovo keyboard with trackpoint:

But I don't like it because it's not full-size, and I don't really need\nthe trackpoint.

\n

One option which looks promising as well is MS Natural Ergonomic 4000:

\n

\n

because of two extra buttons below the spacebar. Again Not sure if they can be used to emulate mouse click.

\n

So ideally I want something like the Japanese keyboard, but only if I can really make use of those keys\nin the bottom row.

\n

Questions:

\n\n

Ideally the keyboard should be easily available and not very expensive. Obviously there is something\nlike ErgoDox, but I am not ready for this investment of money and time yet.

\n", "Title": "Keyboard with extra thumb keys (below or near the spacebar)", "Tags": "|keyboards|windows|ergonomics|graphics-tablet|", "Answer": "

So, here is my \"happy end\" story. I could not find more good options \nso I was a bit on the fence about what to buy ... and know what? Recently I was in the local computer store and what did I see! There is a keyboard sold which is exactly what I need. It is A4Tech X7 G800V model, a budget (~30$ in Russia) keyboard with extra buttons below the space bar.

\n\n

Now I am really puzzled why google was so inefficient on this when I ve been searching for \"keyboard with extra buttons\", \"extra key row\" etc. and what not - nothing valuable popped up.
\nAnd almost by accidence I have noticed this keyboard in the local computer store.

\n\n

I have bought it and have been testing it for a week, and I am very pleased, so I've \neven decided to write about my experience so far.\nHere is a link to the product: \nhttp://x7.a4tech.com/product.aspx?id=87

\n\n

image:
\n\"enter

\n\n
\n\n

Note: there is another very similar keyboard, G800MU, but it is not suitable for the described needs, because it has no possibility to reprogramm the extra keys, whereas the G800V has this possibility, so be cautious when buying.

\n\n
\n\n

So what I get:

\n\n

Fully reprogrammable extra keys - 15 keys total (gray keys marked with G and a number). \nThere is a software \"X7 Oscar Keyboard Editor\" in the downloads and its very easy to use - no reboot \nrequired to reprogramm the keys. So you can reprogramm any G-key to any key, mouse button, or even some macros and more. And that is really cool. Absolute no problems or glitches with that so far.

\n\n

Overall very good build quality and materials (despite first impression mainly because of childish red WASD keys).\nIt is a membrane keyboard, but feels really good and smooth - low resistance force and short travel reminds me of \nsome 90's Chicony keyboard feel.

\n\n

Now to the best feature - extra keys below the spacebar is what I needed so much: now I have both mouse buttons \non my keyboard in a comfortable position under my thumb and don't need any software tweaks and manipulations. \nWorking on a graphic tablet finally became comfortable (thanks heaven and a4tech).\nSo I just disable the \"click on tip touch\" feature in the graphic tablet driver and bind the G-7 key as left mouse button.

\n\n

Very nice bonus - an extra key (G-11) near the ESC key - for now I have bound it to 0 key so I can type numbers like 10, 20, 30, 01, etc. with left hand easily.
\n

\n\n

Few minor issues that I have noticed:

\n\n

Strange decision from a4tech to place the left Alt key below the Z key and to put G12 extra key on its place - this is IMO mistake, BUT - you can easily reprogramm this G12 key to Alt and the problem is solved, that's what I did, so in \nthe end my Alt is even better placed than on many modern keyboards.
\nThe G1-G4 keys (oval keys on the left side) are really hard to press, no idea why they made it so. Definitely those could be more useful if they worked with less force.
\nThere is no replacement keycaps for those red silicone keycaps (not a real issue though).
\nThe legs are a bit small, I'd want to raise the angle more -- needed to put some 10 mm blocks under the legs \nto raise the angle more, but that is individual preference I think.

\n\n

Happy end :-)

OK, three part answers:

\n\n

I am unaware of SPF(+) to copper interfaces. That does not mean that they do not exits.
\nIf they do exist then compatability is not a guarantee, so a call to HP is probably a good idea. If only to get an article number to search further on, since I expect the HP price to be 'not low'.

\n\n


\n\n

Based on the goal that you just need two additional 1 GbE ports:
\nSwap the card. PCI-e cards with 2 or even 4 interface to regular copper are common, relative cheap and just work.

\n\n

I linked to two potential cards, but theere are many more than just these two:

\n\n

I/O Crest 4 Port Gigabit Ethernet Intel i350-AM4 Chipset PCI-E X4
\nMentions server 2012 support on the box.

\n\n

Quad 1GBit Intel PRO/1000 VT Quad Port Server Adapter LP PCI-E EXPI9404VT
\n2 more ports and is still affordable.

\n\n


\n\n

For future compatability and less down time (e.g. not swapping to a newer card if you get a more capable switch in the next year or two), try regular copper cards with higher speeds.

\n\n

There are now desktop cards which support old format (100/1000mbit), but also 2½Gbit, 5Gbit and 10Gbit. Those could be used at the old speed with the current switch, and with a more modern switch you could do higher speeds.

\n\n


\nSome more notes:
\nWe have at least two generations of these cards already, and that the older ones draw a relative high amount of power. That makes this a trade off between adding a classic 1GBit multiport card now and upgrading later. Or spending a relative large amount now and having less downtime later.

\n\n

Modern DP proliants (G9 or G10) often come with something called 'flexible LOM', where you can choose for native 10Gbit rather than for a few 1Gbit ports.

\n\n\n\n

Quick googling finds a few examples of 10Gbit copper, but at not entirely trivial prices. \"Two One of which seems suitable for a server with high internal airflow and no single point of failure fan.

\"Seems to lag a bit\" is quite a wide definition. An SSD will speed up start-up of applications and responsiveness of the system when the HDD is under load.

If the computer stutters when playing video, that would be a different problem, it would mean that the CPU is too slow to decode it and the GPU is not helping because it's either too old/weak (doesn't support decoding modern video formats) or it potentially could but Linux drivers don't support it.

\n\n

You can see CPU and memory usage in a program called htop (can be installed from the repositories), that can also tell you where the problem could be. In any case, don't expect any miracles. I've been running a very highly clocked Core 2 Duo with 8 GB RAM and an SSD on a motherboard from 2007 and sometimes could not figure out why it was so slow compared to a nimble laptop with 2014 tech. It's just... old :)

Use the NVR.

\n\n

It\u2019s a dedicated piece of equipment that will consume less energy than a windows 10 computer. NVR\u2019s also contain different hard drives that are specifically made for constant writing and over-writing of video (they last longer).

\n\n

In my house the NVR is tucked away (and cleverly disguised) on a closet shelf. This adds to security as an intruder likely wouldn\u2019t be able to find it. (They steal it and you lost your video of the event.) (Remember if you choose to hide yours that it does need proper ventilation and should not be in an unconditioned space like an attic.)

\n\n

We did need to attach a keyboard, monitor, and mouse to the NVR briefly during initial setup. We set the password and configured the network settings. Once that is done we shut the system down and removed the keyboard, monitor, and mouse. Then powered it back up without. This configuration is called \u201cheadless\u201d, and the unit has been in use for years without monitor, keyboard or mouse. Any of our windows computers can be used anytime to view and download video, and the computers don\u2019t need to be turned on all the time.

I am looking forward to invest in a good GPU/ASIC for Machine-Learning research. I do not want to choose any of NVIDIA's consumer-grade GPUs as they are mainly gaming oriented and the price I'd be paying wouldn't be justified as I won't be using any game-play oriented features like Ray Tracing. And also, the previous generation GPUs' prices have gone up despite the launch of new 20XX series making the 10XX not a good buy.

\n\n

AMD's consumer-grade GPUs aren't still powerful enough as their counterparts and their enterprise-grade GPUs are too costly and don't justify the price to performance ratio.

\n\n

Recently, Habana Labs announced their ML oriented chipset but its samples ship Q2 of 2019 and I might consider waiting if it is justified.

\n\n

So, are there any Good consumer grade ASIC/GPUs for ML?

P.S: I don't mind library support

The closest to what you are asking is NVIDIA Tesla - it's dedicated, does not have even single DP / HDMI output, it's power efficient and is optimized for 'AI'. See NVIDIA Tesla T4, NVIDIA Tesla V100, NVIDIA Tesla P100, NVIDIA Tesla P4/P40. Whether it's most cost efficient depends on many factors. If you're buying for a larger institution, take a look at data center solution based on Tesla V100.

\n\n

The second candidate would be NVIDIA Jetson. It looks to be designed for ML / AI in robotics, as an end-to-end solution (as opposed to agent communicating with server). It's a dev kit, including ARM CPU, GPU, RAM, eMMC storage and 2 DeepLearning accelerators, at a price tag of 2.5k $ (but it's small!). \nI could not find any benchmarks, but they state, that it's 20 times faster and draws 1/10 of electricity than it's predecessor, NVIDIA JETSON TX 2, which was benchmarked ex. here.

\n\n

Having said that, it really depends on your use cases - if you will profit from it's modularity, dont' have any other hardware bought for the setup and will use it as embeded (like you'd use RaspberryPi), that NVIDIA's Jetson is perfect. If you want to make a server for AI, I would consider RTX 2080/2080ti as user9313 suggests and NVIDIA Tesla line, and peak whichever is most cost efficient for you - which is impossible to say without knowing the framework / library you'll use. Also, as mentioned by user9313, the cloud is already a viable option, not only Google 1,2 but also Microsoft has good APIs and even cloud IDE.

I originally asked this question on AskUbuntu, but I haven't gotten any replies so I figured I'd also ask here.

\n\n

I am looking to set up an e-mail server with Ubuntu Server, although I am open to alternate operating systems if you have any suggestions that may perform better for my use case. I will have some 19,000+ devices using it to send and receive e-mail. The majority of these devices will probably not be heavily used, as only a few of our clients use the e-mail feature in these devices.

\n\n

Based on the recommendation of another StackExchange user, I will likely be setting up virtual mailboxes for these devices to cut down on resource usage.

\n\n

My planned software stack for the mail server will be Postfix, Dovecot, and MySQL. If there are alternatives that would perform better for my use case, please let me know.

\n\n

The current usage data I have from our old system shows about 14GB of data across 7,684 messages received and 22GB of data across 11,321 messages delivered per week, adding up to around 56GB across 30,736 messages and 88GB across 45,284 messages received and delivered per month, respectively. As a rough estimate, I would say that the server will probably be sending/receiving around 100 to 200 GB across around 100,000 messages per month.

\n\n

I do not need a large amount of storage per mailbox. The devices receiving mail will only be looking at the messages once to parse them for simple text-based commands. Sent mail does not need to be stored on the server at all, and received mail will be deleted from the server as soon as it's processed by the device.

\n\n

Based on these figures, I would like to know what the minimum system requirements would be for the server to be able to handle this volume of messages/data smoothly.

\n", "Title": "System requirements for e-mail server processing 100 to 200 GB of e-mail per month", "Tags": "|server|", "Answer": "

If you are going for cloud solution, processing power is the main concern, as opposed to the network bandwidth - which would be primary concern if you'd be buying server yourself. The throughput you specify should be easily handled by any modern PC. Let's focus on the peak throughput - you calculated it is 23 messages/min, let's make it 100 for a pessimistic scenario. As the single outgoing message is at max 10MB, that means a pessimistic 1GB/min ~= 17 MB/s.

\n\n

For minimal requirements & recomendation:

\n\n

CPU: I would reccomend any at least quad physical core processor with benchmark value at least 10 000 here: https://www.cpubenchmark.net/high_end_cpus.html

\n\n

RAM: the second most important component. I would recommend 8GB minimum - it will depend though on what distro you choose and specific software. Also - you mentioned databse, yet you said you will not be storing the e-mails - the database caching can take considerable amount of RAM, so if you plan on using databse only for logging, 8GB should suffice, but not for much more.

\n\n

Mo-Bo, PSU and other components are not a concern if you go with hosting.

\n\n

Comparision, for the on-site server:

\n\n

So with a budget less than 200$ a month, you can calculate, that 2000$ server will reach a full ROI compared to hosting provider after 10 months, excluding electricity and upkeep cost.

\n\n

Would you like to include electricity and faulty drive(s) swap:\nThe electiricty cost can be estimated at around 400$ per year serverpowerusage. This makes 12 months of ROI.\nAccording to this article you can expect 0.1 failure rate in two years per drive ~= 1 faulty drive in twenty years. This is negligible.

\n\n

Also, you need to calculate the cost of man-hours to setup and maintain, and theese are the biggest. There is also a bigger chance of data loss and problems, would you forget abiout spare PSU, ECC RAM or disk swap. You need to calculate it yourself.

\n\n

Would you consider buying the server, that's what I'd reccomend paying attention to:

\n\n

CPU - it's not a bottleneck in this usage scenario assuming you buy any decent new server, but the older platform you will get, the more troubles in the future you will have upgrading. I'd say go with latest chipset, leave one socket empty and buy cheapest XEON for the second. It will be idle anyways most of the time.

\n\n

RAID support and hot plug of HDD and PSU is a must.\nRedundant PSU is a must also.

\n\n

As for RAM - just remember to buy ECC ram - you have a server on site, so you can easilly increment. Start with one stick of 8GB or 16GB. More important is the board, which should have planty of space to add new RAM dies (12-24 ideally).

\n\n

Whichever way you'll go: keep in mind the 3-2-1 backup mantra: 3 copies at 2 different media with one copy at different location.

What is the difference between EVO and PRO in first place?

\n", "Title": "What is the difference between Samsung EVO and PRO SSD", "Tags": "|ssd|", "Answer": "

I believe the main difference is hard drive durability/life time. Depending on the series of the Samsung SSD, the pro sometimes have faster read and write. The newest 850 series in particular does not seem to be all that different in performance with the exception of write speed.

In general, the EVO series are going to be much better value, and usually the better option.

I need a system with absolutely no wireless capabilities for my small business that will solely operate through a wired LAN. Since I have no need for WiFi or Bluetooth, I\u2019d prefer not having to deal with contigencies stemming from possible unauthorized wireless injections or WiFi packet sniffers. I\u2019m not willing to simply turn these wireless signals off through my system, because I for one know, there exists many firms which have stringent rules against the use of WiFi chips within their mainframes. Thus, I\u2019m just not content with having any sort of antenna within my system. I\u2019m currently considering getting a chrome box because I won\u2019t need the system for any hardcore applications, but simply an internet connection. Any useful resources would be helpful.

\n", "Title": "Does a System with Absolutely no Soldered Antennas Exist?", "Tags": "|wifi|desktop|security|home-security|", "Answer": "

Let me clean up the question a bit as I understand it first; you want a device that will give you internet capabilities for a browser and possibly some other applications (but mostly the browser). It cannot have a wireless network interface component because you are concerned with infringing on company policies regarding wireless access within their networks (a mainframe is a very different thing and has nothing to do with wireless networking).

\n\n

Before I answer, I'd like to point out that any company worth anything at all has abandoned the practice of forbidding wireless devices, as cell phones exist and are microcomputers with wireless network accessibility. Any company with which you'd want to associate will have a modern philosophy about cybersecurity and prohibit unauthorized connections technologically so you don't have to worry about it.

\n\n

You will be hard-pressed to find a notebook computer that doesn't have wireless LAN access. Most motherboards have them built in and your only option to disable them is via the BIOS, which is effectively a secure way to make the machine behave as if it has no wireless card at all (since a BIOS hack is not a realistic problem). All Chromebooks have WLAN access components. Most laptops do not possess a normal network jack anymore and you'll need to get an external RJ45 port on a USB dongle to use physical networking lines.

\n\n

Since laptops simply aren't made without WLAN capability anymore, your only option other than just disabling it yourself is to physically remove it yourself. Some Dell Latitude and HP models have the card (the size of a small cracker) in a slot on the motherboard with two screws holding it down and antennae that lead to the monitor. Disconnect the antennae wires, wrap their contacts in electrical tape, and remove the card.

I would like a desktop computer which is fast and snappy for common \"power user\" workflows (eg. coding IDEs, 20+ Chrome tabs, Blender, Audio Editing, Web/File Server, Backup server) and also has the capability to run deep learning algorithms on it (one nVidia RTX 2080 ti to start, maybe another down the road). The problem, as I see it, is that Intel doesn't really offer any high-performance CPUs (>= 5GHz overclocked) with more than 16 PCIe lanes. I've seen different reports about whether NVMe drives use up these PCIe lanes or if they are routed through a different set of platorm PCIe lanes, but if they do use up some of these lanes then I am immediately dropped down to 8x performance on the graphics card. Even if not, it means dropping down to 8x performance once I have 2 graphics cards.

\n\n

Bearing in mind that a setup like this will reasonably end up with 2 NVMe drives and 2 graphics cards, am I better off going with a lower clockspeed Xeon or AMD Threadripper so that I get the PCIe lanes?

\n\n

I'm getting the impression, based on current hardware options, that I can have a fast desktop PC or a capable server / deep-learning platform, but not both.

\n", "Title": "Is a Deep Learning + High Performance Workstation impossible with current hardware offerings? (Late 2018)", "Tags": "|graphics-cards|processor|pcie|", "Answer": "

It really depends on how deep you want to go when it comes to your deep learning projects, and how long you are willing to wait, which could be a long time- depending on your project and how much computing it requires to output qualitative results.

\n\n

My primary workstation is a Dual E5-2697 v2, 128 GB RAM, Dual TITAN GPUs, and an 8x1TB SSD RAID 0 Array over SAS. It's a workhorse; the CPU rates 22000 using Passmark and is in the 99th Percentile. The 2X GPUs rate at 92nd Percentile...

\n\n

That said, it's a heavy duty system (The original build was roughly $20,000- though it could be built now using the same components and buying used for far less)- but it even wouldn't really be a \"great\" system for workload heavy deep learning setups, such as video/image/audio projects.

\n\n

Your best bet would be to buy a good system, I would say don't buy \"best\", but 6 months post release- it's so much cheaper that way. Go single processor, highest OC you can afford, and a decent GPU.

\n\n

Then use the money saved to run your actual deep learning projects on Google Cloud Compute or Amazon's AWS.

\n\n

You can build your VM Instance on Google's Cloud Compute Platform, keep it off which will only incur minimal charges for the IP and system image; then power it up with 1, 2, 4, or even multiple VMs running NVIDIA V100 GPUs.

\n\n

The V100s will really give you the power you want and while the 2080 card may appear nearly as fast on benchmark charts, it simply can't do what a V100 can, such as FP64, it can host 32GB of RAM which vastly improves it's ability to handle large data sets rather than having to pipe in and out smaller subsets, and you can rent them at the pre-emptable price of roughly $0.80 per hour. (GPU only)

\n\n

The 2080 may be touted as \"80% as fast\" as a V100 but if your project would benefit from FP64 and larger ram allocations, it will rip past what your 2080 can do- it's why the card costs 8 times what a single 2080 is priced at.

\n\n

Add to that you can instantly launch a 2 x V100, or 4x V100 VM Instance, and suddenly you are machine learning speeds are 20x, 30x, or far more, than what your system could do.

\n\n

Ultimately, it will boil down to: I can run this machine learning project on my system and obtain the results I want in 9 days, OR, I can launch a VM, pay $8.00 an hour, and get my results back in 7 hours.

\n\n

Using this method you can build your projects on your system, then when you actually are ready to let the machine go to work and do the work, you can put your VM online, transfer your project and assets, and put the V100s to work for a few hours, or a few days.

\n\n

But a high end deep learning system on Google's platform - using the pre-emptable price; may cost you $4 an hour; what it will be able to do in 12 hours will far surpass what you would be able to do in days, if not weeks and weeks of runtime.

\n\n

The cost of one V100 is over $8000. Save the cash, rent the cards by the minute when you need them. And costs will drop as newer cards become available.

First of all, I'd like to start by saying that the throw ratio for this projector = 0.133 is very good. If you put a different lens on it, for example that can focus when 70cm away, then your image would be 210\" wide. In other words, you can get a larger image size simply by moving the projector farther from the wall, provided you can find a lens that can focus that distance. The projector you posted is very, very good.

Therefore, if you can purchase a lens to project a 150\" image with such a low throw ratio, for such a low price -- I'd take it.

\n\n

However, in case you are truly dedicated to getting a larger image, I will outline your choices. I checked the projectors on Tocopedia, and the below projectors are not available there; however, all of the below projectors are sold by companies which Tocopedia carries, so I suspect you can get them easier than some other products.

\n\n

Option #1: you can buy the NEC PX803UL with a NP39ML lens. As you can see, this would result in an image of 100 - 350 inches, with a Throw ratio of 0.38 : 1.

\n\n

Option #2: the Hitachi HP-WU9750B or LP-WU9100B, with a FL-920 lens. Again, this would result a Throw ratio of approximately 0.327, and an image of 100 - 350 inches.

\n\n

Option #3: In case you can have a little bit of leeway, and mount your projector 2.1m away instead of 2m away, there is the Hitachi CP-SX12000 or CP-X10000J with the USL-801 lens. Its Throw Ratio is 0.42, and it can project an image 40 - 700 inches. This lens only costs $2500, which is pretty cheap, so it might be worth buying this lens first, and seeing whether you can retrofit it onto a cheaper projector.

\n\n

The projector itself, although fairly expensive, actually has specs a little worse than the projector you posted. For instance, for the SX12000 it's 1050x1400 pixels instead of 1920x1080, 2500:1 contrast ratio instead of 5000:1, etc.; the specs are even worse for the CP-X10000J. But then again, the price of this projector is about half the price of #1 and #2.

\n\n

Bottom line: I think that the projector you posted is very cheap, considering it has true HD, and such a high contrast ratio. It is also about half the price of the last projector I posted, so is a good deal. If you are willing to sacrifice image quality, and so much more money, in order to get a bigger image size, then projector #3 is your best choice. But even then, I would buy the lens first, and only buy the projector if I cannot find a way to retrofit the lens onto a cheaper projector. The first two projectors are great, but very expensive.

Looking for a recommendation from users who personally tested some laser rangefinders (laser-tape). (So do not want recommendations based on the device specifications - (marketing blabla))

At lower distances usually the measuring error is even 5 - 10 mm or more. So, let say if I want measure the inner width of my doorway (78.4cm) want get accurate result (max.) +- 2mm.

I have a Bosch DLR165, which appears to have been produced around 2010. It's possible that I purchased mine that far back, or from eBay in later years. I found only one in today's eBay listing, but based on my experience with this one, I'd purchase a newer Bosch product with confidence.

\n\n

The manual lists the maximum range at 50 meters, within your requirements. The manual also states a minimum of 50 millimeters. This I checked moments ago. I cannot attest to the precision/accuracy, but can confirm that when placed on a metric ruler, it reads 50 mm. I used an uncalibrated eyeball to place the tool and the opposite surface, but suggest that it would be within the specified 1.5 mm capability.

\n\n

When moved one mm closer, an error message appeared.

\n\n

For a different type of test, I measured the span of my door frame. The top and bottom measured 2 mm narrower than the center of the vertical section of the door. When I placed the aforementioned ruler under the tool (1.9 mm thick), the measurement was reduced by 2 mm, indicating that my door frame is warped and that the tool recognized the distance change. Repeated measurements resulted in consistent results.

\n\n

This specific unit meets the \"nice to have\" list as well. As noted in the manual, there is a trigonometric mode that requires one to measure the two legs of a right triangle and the device will calculate the hypotenuse. I have not tested this feature, but have confidence that it will work as described.

\n\n

I have used the continuous measuring mode as well. It is unremarkable in operation and works fine.

\n\n

Bosch has a reputation (in my alleged mind) of creating quality products. It's certainly possible that this device and others from the same company would be made in China, but in such cases, oversight results in expected quality.

Personally, the people that I know of that engage in graphic design typically use and recommend drawing pen tablets like these rather than consumer touchscreens, particularly due to the fact touchscreens do not have good (if at all) pressure sensitivity. These drawing pen tablets do not seem to have any lag.

In order to hear sounds around you in a proper manner, consider that bone conduction headphones will leave your ears open, while allowing you to enjoy music or other sounds.

I don't have live experience with Vive. However, the Vive FAQ says,

\n\n
\n

Important: Use only the same version of base stations together. Different base station versions are not interchangeable.

\n
\n\n

In other words, if Vive Pro accidentally detects the signal from a Base 1.0 station, it will cause significant interference. The reason for that is, that the IR method of communication prevents Vive from locking on to a signal (which would be possible for it to do if the communication were entirely in BlueTooth). Therefore, when another signal of the same frequency comes in, it will cause a disruption.

\n\n

That being said, it's worthwhile to keep in mind that since IR is a more-or-less unidirectional signal, you still should be able to make it work if you are very careful to make sure that the signals from the two base versions do not intersect. Theoretically anyways. In practice, as I said, I never used Vive before, so it might be harder than it seems.

So i'm thinking of purchasing a DELL XPS 15 with a screen resolution of 15.6\" 4K Ultra HD (3840 x 2160).

\n\n

I already have a very nice DELL Ultrasharp 27 inch monitor with a screen resolution of 2560 x 1440.

I did the research and i believe it's better to use the USB type-c (laptop) to DP (monitor) to connect both instead of the USB type-c (laptop) to HDMI (monitor).

\n\n

Is this correct? Is DisplayPort 1.2 better then HDMI to connect a laptop to a monitor?

It is true, DP is a little better (e.g., it supports a higher refresh rate); however, regardless of which one you end up going with, the differences between DisplayPort and HDMI are not very major. Unless you have some technical reasons why one would be preferred over another (e.g. you're running several of these screens, which would overload the CPU, and you need the one with the least CPU usage), either one works just fine, as long as your screen can play the sound which your computer sends. (some lower quality screens have trouble playing HDMI sound)

\n\n

And for the second part of your question, the negatives to connecting different resolutions are also quite minor. For example, when you need to move from one window to the other, you'll be able to move your mouse to, e.g. upper right corner to switch to the other screen, but moving your mouse to the lower right corner will not move it over to the other screen (or vice versa). However, that is quite a minor disadvantage, and for all practical purposes, you should be fine.

The card(s) should perform well (60 FPS+) with a 5760x1200 resolution, and should be able to handle games like \"Shadow of the Tomb Raider\" maxed out.

\n\n

Can anyone recommend a card, or a CF/SLI setup?

\n", "Title": "Replacement graphics card for a R9 290X CF setup", "Tags": "|graphics-cards|high-end|", "Answer": "

5760x1200 is 6,912,000 pixels, which is 1 billion less pixels than true 4k resolution (3840\u00d72160, 8,294,400 pixels), so 4k framerates could be comparable to 5760x1200 framerates (but take it with a grain of salt, as for ultrawide resolutions like 5760x1200 the GPU would need more memory to load textures).

\n\n

So it might be worth to get two GTX 1080 Ti and use them in SLI - according to benchmark they will outperform 2080 Ti for almost the same cost:

\n\n

https://www.youtube.com/watch?v=WiK0bomLrvM

\n\n

That is unless you want to throw money and get two 2080 Ti in SLI - nothing would beat it, but you would spend $1000 more for a marginal increase in performance (and a chance of getting a faulty GPU, since Nvidia's 20xx series were having a lot of troubles and bad chips).

\n\n

You should also consider upgrading your RAM and SSD to max out your rig performance, to something like this Intel Optane in RAID 0 https://www.newegg.com/Product/Product.aspx?Item=N82E16820167440 for storage and at least 32 GB of RAM either at 4133MHz and 17 CAS latency like this G.SKILL F4-4133C17Q-32GTZR https://www.newegg.com/Product/Product.aspx?Item=N82E16820232677 or this 4700MHz Corsair CMW16GX4M2K4700C19 https://www.newegg.com/Product/Product.aspx?Item=N82E16820236447 and also investing in custom professional liquid cooling for your rig, as this will allow you to OC your GPU's and CPU even more.

What I want is to record a stereo input signal on a USB drive or SD card, without the use of a laptop.

\n\n

I have a Dell U2415 24.1\" (16:10) display and I've very pleased with it, except this morning I found out one of the kids hit it with a pan and cracked its display panel.

\n\n

Now I need to buy a new computer monitor and I was thinking of buying the exact same model, only I've stumbled upon this LG 29UM69G-B 29\" (21:9) display at pretty much the same price and I'm tempted to buy it instead.

\n\n

I've compared the specs of both monitors found them to be equivalent in most respects except the LG would give me a much bigger desktop at the same pixel size (~0.26cm if my calculations are right).

\n\n

My only concern is that the LG seems too cheap?

\n\n

My question is - Am I missing something in the comparison between the two displays? Is there some disadvantage in the LG display that explains its lower price compared to other 29\" displays?

\n", "Title": "Please help me choose between this Dell 24.1\" 16:10 display and this LG 29\" 21:9 display", "Tags": "|displays|", "Answer": "

The main difference between the LG and the Dell monitor is that the LG monitor has an \"Ultra-Ultra-wide\" aspect ratio, meaning that you will have a lot more horizontal real estate. I've heard of 21:9 aspect ratio monitors feeling like the real estate of two normal computer monitors which might be a plus or minus to you depending on your usage scenarios. The LG also has a higher refresh rate at 75 hz which technically makes it slightly better for gaming, though most people find 60 to be enough to suit their tastes.

\n\n

Addressing your concern for price, I think that the Dell monitor is a bit over priced. I find that certain big name brands in particular tend to over price their products in comparison to others that have similar specs. I believe that this is the case here at a $400 list price, which is what 2K and 4k monitors can go for. In my experience, DELL products, in general, tend to be either hit or miss when it comes to good value.

\n\n
\n\n

Between your choices in a purely objective sense, the LG monitor will probably be of better value as it has a pixel density of 2.76 (+33% megapixels), has a slightly higher refresh rate (+25% Hz), and also supports AMD FreeSync (this is an anti screen tearing technology see link for more details, I believe you need an AMD GPU for this to apply).

I currently have a mini tower containing an SSD, one 2TB HDD and one 3TB backup HDD. Thanks to this Stack site, I recently installed an Arctic Freezer 11 LP for a CPU cooler, which is now the only fan in my system apart from the one on my Corsair VS550 PSU (which faces backwards, towards the rest of the components).

\n\n

I feel like I need an exhaust fan in there just to offset the high temperatures of my drives, the SSD in particular:

\n\n

\"enter

\n\n

However, I know very little about coolers, so I'm unsure whether a back exhaust fan would be installed to the inside or the outside of my mini tower's back grill. If it's the former, then as well as fitting in the case's back grill size of around 10 CM/3.5 inches, the exhaust fan in question would also need to have a depth of less than one inch to prevent it colliding with the Freezer 11 CPU cooler.

\n\n

To add to the conundrum, I'm on a low income, so the cheaper the proposed fan is the better.

\n\n

TL;DR: I'm looking for the cheapest, quietest low-profile exhaust cooler that will fit in my PC.

\n\n

Would really appreciate some help with this one, I understand there's a lot to consider.

\n", "Title": "What is the cheapest, quietest low-profile exhaust cooler that will fit in my PC?", "Tags": "|cooling|", "Answer": "

Coming from someone with a lot of fans in his system ill share what my experience with them is. The amount of fans is not nearly as important as a good air flow. You need a good way for air to get into you case and (what most people forget) you need a way for air to be blown out of your case. It would be counterproductive to get the one but not the other and as you stated you only have a fan on your CPU and PS this is a bare minimal of fans. (Are you sure your case does not have any fans?).

\n\n

My advice for you would be to see where the air goes now and how you want to get rid of said air. If your desktop is placed inside a desk, hugging the back wall or tucked in a corner be aware that that seriously limits the air flow out of your case. If I was in your situation I would place it in an air flow rich place and not on the floor (which attracts a lot of dust).

\n\n
\n\n

If you want to buy only a single fan

\n\n

Place a fan in the front of your case (if your case allows that) blowing into your pc letting the hot air be taken from this flow to the back of the case.

\n\n
\n\n

If you want to buy two fans

\n\n

Place a fan in the front of your case blowing inwards and place a fan at the back blowing outwards. This would allow cool air to be mixed with the hot air your PS and CPU fan are blowing into the case. The fan at the back would collect this mixed air and blow it out the back since the fan in the front causes the air to be blown to the back of your case. (Dont place it close to the back wall though!)

\n\n

For brand recomendations, personally I really like the be quiet! series and the Silent wings 3 are also quite cheap ~20/25 euro's.

Question

\n

In spite of Dell's recommendation, I intend to replace both of these SSD drives. The question is not about if to replace them; it is about what to replace them for. I am an IT guy and use my computer 12 hours a day. I literally go for the best overall value and / or performance if the price limit allows it.

\n", "Title": "What SSDs (NVMe + SATA) to a high-performance laptop", "Tags": "|ssd|", "Answer": "

I thought about writing a comment first, but since it will be relevant to other people I will write it as an answer.

\n\n

There are a few things you need to consider when doing this upgrade:

\n\n
    \n
  1. Do you really need NVMe SSD? NVMe speeds reach into thousands of MB/s, it sounds impressive, but in real computing, you would see a marginal difference, the real difference being in 2-8%, according to my estimates. Compiling AOSP on my SATA SSD loads my Ryzen 1700x CPU up to 90-95%, and your laptop has a much weaker 7700HQ. Most of the heavy computing you do will be CPU-bound, and upgrading SSD won't help it. You might see some apps taking a second or two less to load.

  2. \n
  3. The only real use for those speeds is actually doing backups. If you can't stand to let them run overnight, then having SSD's is a plus. But with NVMe SSD's you still would be IO bound - to run a backup at SATA III speed you would need at least a 5 gigabit speed, while your laptop only has a gigabit Ethernet adapter, that is just as fast as a decent HDD.\nEven a 10 gigabit would max out at ~1200 MB/s, which your Toshiba KXG50ZNV512G is capable of delivering. To get even higher speeds you would need a Thunderbolt port. You would also need a storage that supports those kinds of speed, so either a RAID 0 NAS or another NVMe SSD.

  4. \n
  5. Samsung's 860 aren't quite as good as you think. Its speed is a bit of a cheat - it uses a cheap flash and a fast caching storage, so after the cache gets filled its speed drops to 120-150 MB/s. If you were to use it intensively you would notice a performance drop.

  6. \n
\n\n

So, my suggestion is:

\n\n

Go for a single 1TB Samsung 970 Pro M.2:

\n\n

It costs about 11400 CZK on the website you suggested, it delivers one of the best SSD performance, and it is the most cost-efficient solution. SSD prices drop and storage increases, buying a 500 GB SSD now would require a sooner upgrade and make it less reusable in future. You would also be able to install your VM's on it, and in this case, it might actually improve VM's performance.

\n\n

\"Samsung

\n\n

https://ssd.userbenchmark.com/SpeedTest/497261/Samsung-SSD-970-PRO-1TB

And an M.2 to SATA adapter. You already have a working SSD, so why not reuse it?

MOBO

\n\n

I don't fully understand all the subtle differences between different mobo models. I know 470x supports SLI and think b450 doesn't. I also know some mobo models have wifi, faster Ethernet and/or better sound and some have more USB ports/PCIE slots. Some even boast a better VRM heatsink (?), not sure if I should care? Also, some boards have negative core voltage and precision boost, I am guessing I shouldn't care cause these have to do with OC? Also, some VRMs are 10 phase (?) and some are 6 phase?

\n\n

PSU

\n\n

I am planning to juice this thing with Corsair RM550x. It should be sufficient. Why should I care about PSU rating like platinum/titanium/gold/bronze? Do they matter? Why would anyone buy the expensive ones?

\n\n

My main question is how do you distinguish between components that you can't benchmark with 3dmark or cinebench? How do you know they are \"better\" budget options? How is it measured? What is the added value? How significant is it?

\n\n

Lots of question, lots of answers.

\n\n
\n

I don't understand the differences between different mother boards' chipsets.

\n
\n\n

The difference is pretty well explained on the Wikipedia page of AM4 socket. Mostly SLI / CFX support and number of ports / slots.

\n\n
\n

I also don't understand how to quantify the difference between motherboards with the same chipsets. How do you measure these differences? Which features matter and why (I am not doing SLI)?

\n
\n\n

Motherboards can include a whole lot of features, like dual bios (two BIOS chips onboard), more slots, better design, software features (OC suites, etc). The quality of components can also vary. The question is: what are you going to need ? And if you don't know, which is probably the case, ask yourself what you're gonna do with the mobo (OC, multi GPU, etc), you'll have the answer.

\n\n
\n

How do I measure latency? How much does it affect performance? I don't understand if 3200hz matters.

\n
\n\n

I'll advice watching LTT video on ram speed.

\n\n
\n

Also, there are a lot of different kinds with 3200Mhz, what are the differences and how do you know? Some brands like and models like FLare X say they are for AMD. What the hell does that mean? How do you make sense of it? Is other memory specifically for Intel?

\n
\n\n

The chips on the sticks can be different. Please notice that Ryzen are quite more tricky on frequency than Intel CPUs, it's harder to achieve high frequency, or to the cost of a higher latency. That's why there are \"Ryzen optimized\" rams. This does NOT mean that other rams won't work with Ryzen, it means that other rams COULD possibly not run at their maximum speed / minimum latency on Ryzen.

\n\n

When I said different chips, I meant different ranges, from different manufacturers. That can be a way of choosing your ram, especially for Ryzen. You can rely on this table for chips ranges. This is an extract of what is written above the table:

\n\n
\n

In general (on Ryzen) you can expect up to 3466 MHz (without BCLK-OC) with Samsung B-Die (on AGESA 1.0.0.6+ Bios Versions), up to 2933 MHz (without BCLK-OC) with Samsung D/E/S-Die (AGESA 1.0.0.5+). Hynix A/M-Die are mostly working @ 3200 MHz with AGESA 1.0.0.5+. Do note that Dual Rank RAM is faster than Single Rank. E.g. 2933 MHz Dual Rank is faster than 3200 MHz Single Rank.

\n
\n\n

It was written for 1st gen Ryzen, but is still quite accurate today.

\n\n
\n

I don't understand what 'SSR' and 'PX' mean? I also don't understand if I should care. How do you tell the difference between these things?

\n
\n\n

I would say SSR and PX have to do with the platform used, but I wouldn't put money on it. What you should care about is the range, a Focus Plus (e.g. SSR 550 FX) isn't the same range as Prime Platinium Ultra (e.g. SSR 550 PD2) and the quality is not the same. Once again, how much you should care depends on what you want / need. Of course, if you have a low budget, you're not going to head toward the highest end 1KW PSUs.

\n\n

I would recommend to consider SuperFlower and FSP as well, they're part of the biggest PSU manufacturers with Sea. Evga is also very good, using SP, FSP and Sea parts. If you don't know if your PSU is good, look at that table. It'll probably give you reviews for the model you're looking for, once you found it.

Your big problem is that you want it to have normal computer connections on the case, honestly. \"Slim and Light\" is the main thing people look for when scoping out their laptop's casing, so even some ASUS Republic of Gamers laptops still only have two USB ports and very little else for connectivity.

I would recommend looking into a Sager. They specialize in customized gaming laptops, and most of the cases they use still appear to have the connections you requested. Your size requirement is in your way on the RAM; 13\" and smaller machines have a lot of tech packed in a small space, and actual physical size of the motherboard is influencing the number of RAM slots you have available or even necessitating permanent integration.

Unfortunately, trackballs are a fairly narrow market with not a ton of demand; unsurprisingly, this means that prices aren't exactly the most competitive.

As you mention that memory is a bottleneck in your computations I would imagine that the rock64 is the best solution with 4gb of memory.

My Laptop is ASUS ROG GL553VD Model, Here is its Summary Hardware Specification:

\n\n\n\n

I would like to ask for a SSD Hardware Recommendation, as I found that 128GB storage is not enough for me, these are my concerns for the SSD Upgrade:

\n\n
    \n
  1. I mostly use my Laptop for Android Mobile Apps Development (using Android Studio Software which is very Performance Demanding), I would like the SSD faster enough to handle Android Studio or other commonly used development software (such as Visual Studio, etc).

  2. \n
  3. I would like to Clone my Digital Licensed Windows 10 from my current 128GB m2 PCIe Nvme SSD and Boot the Windows 10 in the Hardware, so it is expected to able to support Clone Windows Feature and able to boot up in a very fast manner.

  4. \n
  5. I would like to ensure the Hardware to be Cost-efficient type, where it does not Overprice (such as low price ADATA SSD compare to high price SAMSUNG SSD)

  6. \n
  7. I would like the Hardware to be As Reliable as possible

  8. \n
  9. Storage Space should above 300GB.

  10. \n
  11. Budget Around RM500 (USD 120).

  12. \n
\n\n

I been considering whether to replace my current 128GB m2 PCIe Nvme SSD to a new 512GB m2 PCIe Nvme SSD or I should simply get a new SATA SSD which would keep my current 128GB m2 PCIe Nvme SSD instead,

\n\n

My Biggest Concerns is:

\n\n\n\n

Your Experienced recommendations, advises, opinions is much appreciated.

\n", "Title": "Should I upgrade my Laptop with a New m2 PCIe Nvme SSD or SATA SSD?", "Tags": "|hard-disk|ssd|sata|", "Answer": "

Personally I would not throw away that 126 GB PCI-e SSD as you've already paid good money for that drive. Based on your spec sheet, you have one more SATA III slot that can accept a 2.5\" Drive. Unless your PCIe drive is giving you problems from a speed perspective it is not worth replacing that drive. You likely won't see that much of a speed difference in visual studio build speed unless you're like me and have allocated a part of your RAM for application development (I build applications on a RAM disk for speed and even with non PCI-e drives it can build GB sized applications almost instantaneously).

\n\n

That being said, you should keep your Visual Studio related program files to your primary SSD and send all your other junk to a slightly slower SATA SSD or HDD. This is going to be a lot more economical especially with the budget you specified.

\n\n

I've recommended you Drives that can ship to a Malaysian address today.

\n\n
\n\n

SAMSUNG 860 EVO 500 GB RM 455 + RM 5 Shipping

\n\n

It turns out this SSD option is exactly your budget. Owning a 840 EVO I can tell you these SSDs are excellent and come at a very reasonable price. Also here is a Amazon link in case you find Amazon can offer a better price for your location. I'm not familiar with the South-Eastern Asian Markets so it's hard for me to cull prices specific to Malaysia.

\n\n\n\n
\n\n

Seagate Barracuda 500GB (ST500LM030) RM 158 + RM 5 Shipping

\n\n

In addition, I'll recommend a HDD, as you may not need that much speed for your additional files. HDD are very much under budget and I've taken care to recommend you one of the highest benchmarking HDDs at its price point. Here's the Amazon link for this as well.

\n\n\n\n
\n\n

Finally if you really want, you can completely replace your PCI-e SSD with another one. I would recommend the Samsung 960 Evo, but only the 250 GB variant is under budget. Samsung also comes with cloning software so you can make a completely copy of your system onto any Samsung SSD and just plug it in and operate like normal. I've used Samsung's cloning software and can tell you its pretty painless.

It still amazes me that it's almost the end of 2018 and still no one seems to have been able to, to my knowledge, find or create such a device. I did however gather some more information, so here I go.

\n\n

To clarify what the adapter should be able to do:

\n\n

The USB-C male port is for the host device, aka a phone.

\n\n

The USB-C-PD female port is for power. So it could be connected to a wall adapter with a C-C cable and provide power to the host device (and maybe also for the second device).

\n\n

The USB-C data female port is for USB devices that can be connected to the host device, aka a flashdrive, mouse or 3.5mm dongle (with DAC).

\n\n

For reference, I own a USB-C hub that does all these things, however it's very large (especially for a phone) since besides these ports it also packs in an extra USB-C port and two USB-A 3.1 ports. I'm talking about the Aukey CB-C48\nhttps://www.aukey.life/products/cbc48-usb-c-hub-2-port-usb-3-0-2-port-usb-c-1-port-usb-c-with-pd. This device existing, shows that the idea of a \"splitter\" is actually possible, just never done before (to my knowledge).

\n\n

The size I'm looking for is around this size: \"this\n(Don't be fooled by its appearance, the adapter in the picture only wires the lines regarding power one way, while it wires the lines for Analog-Audio-over-USB-C the other way, which is great, if you have a phone with a DAC and only want to use it for headphones but not for anything else.)

\n\n

Another option would be this form factor: https://hackaday.io/project/26263-pd-buddy-wye. (This one works the other way around, allowing your phone to fast-charge over PD from a charger and connect to a PC via USB. It doesn't allow the phone to be the host.)

\n\n

Finally I found another adapter of which I do not know whether it works: https://www.amazon.com/gp/product/B07KSZMG5J?pf_rd_p=1581d9f4-062f-453c-b69e-0f3e00ba2652&pf_rd_r=SMDQYBNA8X75H9EGVK16. These types of adapters have a DAC inside them,thus enabling phones without a DAC to connect to USB-C headphones (or dongles) without DAC. At least that's what I've gathered from the descriptions. However, I don't know if the port can also be used for other USB peripherals. The seller did tell me it didn't work with mice/flashdrives, but it did work with the 3.5mm dongle from Google, which is odd, because it does have a DAC inside and thus is a completely normal USB peripheral, just like a mouse for instance. I did order one to test what's true and what isn't about these. When mine arrives, I'll update the post.

\n\n

Edit 1: Another item I found was the Cusby, a failed indiegogo campain: https://www.indiegogo.com/projects/cusby-first-usb-c-modular-expandable-adapter and http://www.cusby.com/. In particular their \"power port\" module does exactly what I'm looking for. Unfortunately they've been silent for 3 years now, so yeah...

\n\n

So if anyone finds anything, please let me know and if anyone has the capacity to design and build such an adapter also let me know. I really hope it can be realized!

These small splitters should be avoided at all costs. As Benson Leung's post explains

\n\n
\n

There are no active components inside. It bridges many pins (power, data, gnd, cc) among the three USB-C connectors). What this means is that your phone or laptop can negotiated much higher voltage than vSafe5V, and that will just magically show up on the other USB-C receptacle.

\n \n

If the other USB-C receptacle has a headphone or a USB-C thumbdrive or a USB-C Yubikey that is only 5V tolerant, it will be destroyed.

\n
\n\n

A later post by someone much less famous but nonetheless correct:

\n\n
\n

A proper adapter would need a buck converter for 5V, a power switch on the downstream data port, and two USB PD interfaces with good firmware that implements proper derating. Essentially a full blown charge-through hub.

Preface

\n\n

First and foremost: what card is best for you will depend heavily on your specific workload, down to often even relatively small details. Things from what you're modeling, render settings, and even what format you're exporting to can influence what card works best for you massively. Unfortunately, spending more doesn't mean you'll be getting better performance, and outside of the very best Quadros, doesn't even guarantee the same level of performance. What I'm trying to do here is provide you with a general recommendation of what will probably be good given your (somewhat varied) workload. If it turns out that you're really doing one thing in particular, either come back here for more specific recommendations or contact the developer/a third party consultant who specializes in the tech for a specific recommendation.

\n\n

Second: I am by no means an expert when it comes to hardware-accelerated GPGPU. The world of GPUs, even compared to others in the industry, is a particularly messy one, and I make no pretense that I understand it all or even close to it. If you want a brief and very interesting (while slightly terrifying) look into the world of graphics, I highly recommend this post on the Dolphin Emulator blog on ubershaders.

\n\n

That said, let's get into it.

\n\n

Graphics APIs

\n\n

Understanding what GPU is best for you requires understanding how GPUs interface with software. Based on your background, I'll assume you understand the basic premise between APIs, but it's worth reviewing them in specific for macOS, since it in particular sits in a bit of a weird space when it comes to graphics APIs. For the purposes of these programs, macOS has three different graphics APIs: OpenCL, CUDA, and Metal. OpenCL is cross-vendor and cross-platform, working on AMD, Nvidia, and Intel (plus others) GPUs with Apple's out-of-the-box drivers on macOS. CUDA is specific to Nvidia GPUs but cross-platform, installable with Nvidia's web drivers on macOS. Metal is the newest of the bunch, written by Apple for their OSs with support for AMD, Nvidia, and Intel (plus others) GPUs. So, which to choose? Well, it's not so simple. Metal and CUDA tend to provide \"better\" access to the hardware, at the cost of the developers. Although Metal might seem like the obvious first choice, because it's so new and specific to Apple's OSs, performance is often somewhat lackluster, if developer support exists at all. OpenCL might seem like a solid bet, but because Apple wants to push Metal, it refuses to provide drivers past version 1.2, even outright deprecating it with the release of macOS 10.14 Mojave (somewhat ironic given Apple is the original author of OpenCL.) Additionally, Nvidia GPUs tend to perform worse with OpenCL compared to CUDA. CUDA, meanwhile, suffers from the obvious burden of only supporting Nvidia GPUs and lackluster support from Nvidia themselves.

\n\n

This has left software vendors in a bit of a tight spot. Many have existing support for OpenCL (and sometimes CUDA) based hardware acceleration, but don't see a clear path forward. No matter what option they choose, they're either alienating part of their consumer base on the basis of their hardware choices, getting less performance than they could, or spending more time and resources developing their software. As a result, developers have basically scattered when it comes to what graphics API they use on macOS.

\n\n

For this reason, this will be considered on a program by program basis, along with hardware.

\n\n

After Effects (and sort of the rest of CC)

\n\n

In the timeline, After Effects supports some effects and fast rendering on GPU using OpenGL for most, and CUDA only for a few.

\n\n

As it stands, Media Encoder still favors OpenCL over Metal for encoding. Or maybe not? Initial testing with Adobe Media Encoder 2019 (which has a bunch of improvements on the Metal front) actually yielded a 11% (1:20 vs. 1:30) improvement with Metal transcoding from a H.264 screen recording to H.264 Youtube 1080p... so maybe not? In any case, I won't be considering this for now because of the wonky state of Metal at the moment (more on this later.)

\n\n

Let's get down to the benchmarks:

\n\n

\"enter

\n\n

Conclusion? More raw power is better (but not by a ton); Nvidia is favored somewhat over AMD; \"Pro\" features don't matter.

\n\n

Maya

\n\n

Viewport

\n\n

Unfortunately, numbers for the RTX series aren't available here. However, we can still get a pretty good idea of things.\n\"enter

\n\n

Rendering

\n\n

AFAIK, Maya doesn't support GPU-based rendering. While I believe there are other renderers which do, I don't feel I'm qualified to talk about them here.

\n\n

Conclusion? More raw power is better; AMD and Nvidia appear roughly equal; \"Pro\" features are favored by ~5-20%, but which features are important is unclear.

\n\n

Cinema 4D

\n\n

Viewport

\n\n

Unfortunately, SPECviewperf numbers aren't available for Cinema 4D AFAIK, and I haven't been able to find a good replacement. Will update if I find something.

\n\n

Rendering

\n\n

Cinema 4D is really simple: no support for GPU rendering!

\n\n

...until it's not. While the \"normal\" rendering engine doesn't support GPU acceleration, Cinema 4D offers the ability to use a variety of other rendering engines, including Arnold, Octane, Redshift, and even Blender's Cycles engine. However, these might as well be considered separate programs, so I won't actually be covering those here.

\n\n

Except, starting with release 20 on September 1st, 2018, Cinema 4D includes built-in support for the Radeon ProRender rendering engine, with support for OpenCL and Metal based acceleration. Unfortunately, because it's new, numbers are hard to come by. So far, all I've managed to find is this set:

\n\n

\"enter

\n\n

Note also that these numbers are with OpenCL on Windows 10 Pro and don't include the RTX series.

\n\n

Conclusion? More raw power is better; AMD is favored over Nvidia; \"Pro\" features don't matter. However, things are fast-moving.

\n\n

GPU: The final decision

\n\n

Based on your budget, ~$500 seems reasonable for your graphics card.

\n\n

Frankly, the extra expense of a \"pro\" card doesn't make sense for the relatively minimal gains in Maya. Because of the much better availability of consumer cards, I'd highly recommend one of them over a pro card.

\n\n

Going for straight power, a used GTX 1080 should be well within reach; and, if you're willing to shop around a bit, a GTX 1080 Ti should be doable. Right now, AMD's offerings just aren't competitive at this price point; used 10 series cards are far cheaper and available compared to Vega cards, and no AMD card can match the 1080 Ti ATM.

\n\n

However, it must be noted that Nvidia cards are currently unsupported on Mojave, and other than Kepler, Metal drivers are absent, making it impossible to upgrade to Mojave. However, it seems likely that Nvidia will release drivers (with Metal support) in the future. Just when exactly that future is is unclear. In the meantime, stay on High Sierra.

\n\n

Note also that Thunderbolt 2 and Nvidia eGPUs are unsupported by Apple and require extra work for macOS compared to the plug-and-play of an AMD card on Mojave with a TB3 equipped Mac. Since you've got a Thunderbolt 2 equipped laptop anyways, I'm going to recommend this setup anyways. Just keep this in mind.

\n\n

eGPU enclosures

\n\n

eGPU.io is a fantastic resource for everything eGPU related, from hardware recommendations to build guides. Information is generally quite recent, and the forums there are extremely useful.

\n\n

I'm going to recommend using a Thunderbolt 3 eGPU enclosure with an adapter, rather than a Thunderbolt 2 enclosure. While Thunderbolt 2 enclosures can be cheaper, they're usually harder to find, have much, much lower power limits, and aren't great for upgradability.

\n\n

eGPUs are a bit strange in that there are a bunch of different enclosures available, all of which are fairly valid choices. While I'm going to make some recommendations, if you find yourself looking at something else, there's nothing wrong with that. Again, the eGPU.io buyer's guide is a fantastic resource.

\n\n

AORUS/Gigabyte Gaming Box with a preinstalled GTX 1080 \u2013 ~$650?

\n\n

This box is a pretty good deal at $670... if you can find one. Unfortunately, as far as I can find, they're completely out of stock in normal retail channels. However, they're still in good supply from 3rd party resellers for around $600 with the card, and often significantly less without the card.

\n\n

\n\n

Frankly, most of these features are probably unimportant given your laptop and the already beefy PSUs included out of the box. So, it's really a toss-up IMO.

I suspect that 10-Gigabit switches are only really used in enterprise level applications as you are unlikely to actually pass the Gigabit mark without the proper servers, cables, or otherwise environment.

Dear hardware enthusiasts, I need your advice.

\n\n

My 4 years old gaming PC is currently running 2x GTX770 in SLI. I plan to upgrade to a single powerful gaming card. My budget is enough for GTX 1080 Ti, RTX 2080, or below.

\n\n

I'm considering two aspects:

\n\n
    \n
  1. I wanna feel major performance improvement (fps) in games, and
  2. \n
  3. I wanna avoid that another PC part will become a bottleneck so that the new card won't be used effectively.
  4. \n
\n\n

I do not plan to do another major investment so I will rather buy a lower card if the more powerful would make no sense on this setup. What card would you recommend me and why?

\n\n

My current setup:

\n\n\n\n

Any feedback will be appreciated.

If you have the money, go for the 2080. It has a smaller architecture, meaning it has lower power consumption and it runs cooler, however all of this is in theory, your mileage may vary. However the 2080 has better support for Real time Ray Tracing, and has support for a bunch of other technologies including DLSS. So if I were you I\u2019d go for the 2080. And it would be pretty hard to have bottlenecks with the 4790K especially at high resolutions where the graphics card would be more taxed than the CPU

I have a Gigabyte F2A88XM-HD3 motherboard which has 4 memory slots. In two of these slots I have two Corsair CMV8GX3M1A133 1333 Mhz DDR3 8G modules.

I have found

\n\n

https://eu.crucial.com/eur/en/advisor

How can I find 8G DDR3 memory modules that work flawlessly with my existing Corsair modules?

\n", "Title": "Searching memory for motherboard and existing memory", "Tags": "|motherboard|memory|compatibility|", "Answer": "

The closest you will get to 'flawless' is a matched set of 4 sticks that are specifically recorded as compatible by the mobo manufacturer.

\n\n

This is not an option for you, if you want to re-use your existing RAM. You could instead buy a matched pair of sticks of the same model as you currently have. While not a fully matched set, you should not have any problems.

\n\n

You are not going to be able to buy a pair of Crucial sticks that are perfectly compatible with your existing Corsair one. However, if you buy a pair that are both supported by the mobo and have the same timings (e.g. 9-9-9-24) as the Corsair ones, you almost certainly won't have a problem. Usually the RAM timings are included in the RAM specs in the online stores.

\n\n

And even if you put RAM with the same speeds but different timings, most modern motherboards can be configured to work in some sort of Auto mode that will find the best fit for your installed RAM. And almost certainly you will not notice any difference in real-world performance or reliability.

\n\n

Summary: If it were me, I'd buy 2 more of the Corsair sticks or would get 2 x near identical Crucial sticks and would expect them to work without any problems, but if you want a placebo level of reassurance, buy a matched set of 4 sticks.

\n\n

Note: it is a good idea when you get new RAM is to run MemTest86 overnight to tease out any potential problems - if you RAM passes such a test, you know you are in good order.

I want to buy a computer which is quiet, i.e. I can leave it in my bedroom without noticing it (under normal load; I might rarely do some heavy processing, where I can accept that I would hear the fan, or on lots of HDD access, it's ok if I quietly hear the HDD; mostly very similar to my MacBook). Also, it should not consume too much energy (because it should run permanently; again similar as my MacBook). It should come in a tower where it is easy to install further disks or other hardware (unlike my MacBook). It also should have wifi.

\n\n

Initially, this will mostly be a fileserver, running Linux. Maybe additionally some software like Perkeep, which needs lots of RAM (10GB or so) as far as I know. But maybe I want to run some other stuff (some scripts, maybe home automation stuff) later on it as well.

The workstation will be for dev and research. For this one, in a nutshell I'm having 2 hardware possibilities, A and B. I'm having 2 important factors: 1) ethernet speed 2) cuda compute. Other factors: system stability at factory frequencies and overclocked ones, extensibility.

\n\n

A. Maximus XI Formula Z390, two 2080ti with NVlink, and a connexion to a hyperconvergent server through a 10Gbit (switch and server) ethernet connexion. The Formula had only 5Gbit connexion. The two 2080ti will have 8x and 8x connexion with the motherboard.

Let me clear up as best I can...

\n\n

I am contemplating pulling the trigger on a refurbished Lenovo M92P OEM Desktop Tower that I found for cheap online, the tower looks like this -->

\n\n

\"enter

\n\n

Currently, the system that I have my eye on is outfitted with an i7 3770 NON-K,8GB of DDR3 RAM and a 500GB HDD from Western Digital.

\n\n

If I were to buy this system, I would want to turn this computer into a cheap gaming rig, and therefore would upgrade the internals to make it game ready.

\n\n

The upgrades I would make would be a GTX 1080 Super JetStream from Palit (2x4pin connectors), one more stick of 8GB DDR3 for dual channel memory support and a cheap 128GB SSD as boot.

\n\n

Now the issue that I am facing is that the PSU that comes with the system is not up to the task, and I know it will fail on me should I go ahead with the upgrades mentioned earlier.

\n\n

My question is simple, which PSU is best for an OEM Machine like this, that uses proprietary connectors and other devices that are not standard?

A side note, my other issue with this is the main power connector on the motherboard, as it is not a standard 24 pin connector.

You can buy any quality 600 watt powersupply and up for your system. Usually anything above $40 with 80 Gold efficiency and up is considered good, make sure to look up the reviews for the power supply. You shouldn't need to spend more than $100.

Answering my own question (it was solved by Bennett Yeo in the comments to my question)

\n\n

First I tried the iiyama ProLite XUB2395WSU-B1 as I was happy with iiyama before.
\nI didn't keep it for long as:

\n\n
    \n
  1. the reported max height of 385mm is actually 410mm

  2. \n
  3. 1920x1200 is too many pixels to fit into a 22\"/22.5\" screen
    \nWhile it is possible to adjust the font sizes of Operating System display fonts, with such a small pixel size (unless you have the eyes of a hawk) you might well need add-ons/extensions for your browser(s) to increase the font size of every web page.

  4. \n
\n\n

Then I tried the Dell U2412M as suggested by Bennett Yeo in the comments to my question.

\n\n

The first one I purchased had a strong colour cast across the screen: pink/yellow on the left ranging to green/blue on the right. I sent it back and ordered one from another source. And this one I've kept.

\n\n

White isn't perfectly white, as suggested in some other reviews. But, colours are consistent over the screen and, if I'd had the iiyama, I would probably have activated the 'reduced blue' mode and ended up with exactly the same result.

\n\n

24\" diagonal is right for a 1920x1200 screen: I increased the OS display fonts by 1pt; web pages are comfortable to read without adjustment.

\n\n

The on/standby light is integral with the on/off button and is a completely unobtrusive gentle orange/blue.

\n\n

The system for adjusting screen settings is the best I've ever seen. Four blank mechanical buttons on the right (above the on/off). Pressing any button activates the menu. Each option in the menu is adjacent to the button which activates it. Brilliant.

\n\n

I have the screen on 'text mode', with brightness adjusted down (20) and contrast adjusted up (80). And for me that gives a very comfortable display.

\n\n

The extra screen 'real-estate' -- 1920x1200 in 24\" vs 1650x1080 in 22\" -- is a pleasure, as I get more vertical text space for viewing/editing code, and more space overall for editing graphics.

\n\n

At its lowest, the top edge of the screen is 410mm above the desk, and the bezel adds another 20mm.
\nI would prefer it lower and, if I purchase another stand to achieve this, I shall post an update to this answer.
\nNB, if you're thinking of doing the same, the stand attachment area is recessed into the back of the monitor by about 6mm. Which does make attaching/detaching the original stand very easy, but does mean that the Wearson WS-03A Adjustable LCD Monitor Stand that I was thinking of using won't work on its own as it has a 'lip' at the bottom of the attachment plate. It is possible to purchase spacer kits, or simply another stand which fits inside the recess. And remember to check the size of monitor it will hold, quite a few are only only recommended for up to 22\".

\n\n

So I'm currently looking at
\nWearson WS-03A Adjustable LCD Monitor Stand
\nplus
\nPart King\u00ae Vesa Bolt / Screw / Washer / Spacer Kit
\nor
\nWearson WS-03UP VESA Monitor Stand on its own.

\n", "Title": "Cloud-free smart bathroom scales", "Tags": "|tracking-devices|", "Answer": "

To avoid a lack of updates needed to fix software issues, let's require that the scales model is either (1) currently in production, (2) supported by a manufacturer's software for their whole range of models or (3) supported by a third-party, open source software that is ideally in current development.

\n

Within these requirements, I found:

\n
    \n
  1. Beurer diagnostic bathroom scales with the orange "beurer connect" logo (14 models). These all work with the Beurer Health Manager app (Android / iOS), for which "the full range of functions can be used locally without registering" (source). In addition, the Beurer BF700 / 710 / 800 models are supported by openScale, an open source app for smart scales.

    \n

    At least in 2014, these were the only off-the-shelf bathroom scales that do not require cloud storage (source), and so far I am not aware that this changed for the better.

  2. \n
  3. openScale supported scales. This includes the Beurer BF700 / 710 / 800 models from above, 23 other commercial models, and a generic hack to transform any scales with LCD into a supported smart scales.

    \n
  4. \n

    There are instructions here and here (including small applications) to modify it so it talks to your own server rather than the manufacturer's servers in the cloud. That own server could be for example a Raspberry Pi in your local home network, making the scales independent of an Internet connection.

My goal is to obtain a productivity setup with quad (four) monitor setup that can handle 3 1440p monitors, and 1 4k monitor for movies (no gaming on that specific monitor). Would 1070ti be enough or do I need another better GPU?

\n\n

Also, I understand for good quality I will use display port and HDMI 2.0 or higher port. Any CPU, Ram size recommendations?

\n", "Title": "Recommended GPU for watching movies on 4k or 1440p quad monitor setup", "Tags": "|graphics-cards|multiple-monitors|displays|", "Answer": "

Specifically answering for Nvidia GPUs:

\n\n

A GTX 1070ti will have no problem at all running 3 2560x1440 monitors and 1 4K for video and desktop computing as long as you are using the correct display outputs and monitors that support HDMI 2.0, DVI-D, or Displayport.

\n\n

You should theoretically be able to run 4 4K screens off of any 10XX, or 20XX series card, or a higher end 9XX series as these nvidia architectures all support 4 displays.

\n\n

For the rest of the hardware:

\n\n

CPU and RAM usage typically goes up as you have more applications open to fill the 4 screens, this will vary greatly depending on what those applications are though. If you update your question with specifically what applications you are using, then I can give a recommendation suited to your workload. Otherwise, any quad core CPU from the recent AMD or Intel series and at least 8GB of RAM will likely be sufficient.

\n\n

Edit:
\nOne more thing that I should mention is regarding 4K video playback. It is possible that some applications or browsers could ignore the video decoding features of your GPU and work the CPU very hard to decode the 4K video. In those cases it's best to have as fast of a CPU as possible. This is likely only going to show up with outdated applications or drivers.

Should I invest in a notebook that offers older processor and the latest GPU or the opposite latest processor with an older GPU ?

\n", "Title": "Should I go for better processor or better GPU for graphics rendering?", "Tags": "|laptop|graphics-cards|processor|rendering|", "Answer": "

As a general rule, I'd recommend having a GPU of the same calibre and age as your CPU. And given your needs, this may well suit you.

\n\n

I'm not an expert in all this graphical stuff, but AFAIK most modellers (inc SketchUp) tend to need to do linear calculations and thus are usually restricted to a single core, so the speed of an individual core is key - so get a good CPU.

\n\n

Whereas renderers like VRay usually use CUDA on the GPU, so perhaps you should prioritise your GPU? VRay and some other renderers can supplement/help their GPU using the CPU, so spare CPU cores may be useful.

\n\n

So in short, get the best CPU & GPU there is!

\n\n

A bit impractical if you are budget-limited? Of course, so have 3 options:

\n\n
    \n
  1. Prioritise Modelling (CPU)
  2. \n
  3. Prioritise Rendering (GPU)
  4. \n
  5. Or hedge your bets with a balanced config - comparable CPU & GPU.
  6. \n
\n\n

So which do you do most of?

\n\n

Back to your sample configs, it is worth noting that the performance gap between the i7 6700HQ and the 8750H is approx 40% (based on user benchmarks). The gap between the 1050 and the 180 however is about 250%. If you want to adopt my balanced recommendation, you'd pair the 6700HQ with a GTX1060 or better.

Recently, my brother has decided to go into Video Editing and Special Effects. He currently has a a laptop, with a Core i5-7300HQ, A GTX 1050 4GB, 8GB DDR3 and a 1 TB HDD. Now. while these specs are pretty decent for a mid range gaming laptop, I don't think it will cut it for using software like Premiere Pro and After Effects, as well as Final Cut Pro X.

\n\n

From what he tells me, he says that the projects he is going to be working on will be \"large\" and \"graphics intensive\".

\n\n

So I've decided to build him a desktop workstation with a budget of around $1000 USD. I've managed to source a Workstation (Brand new) with the following specifications -

\n\n
    \n
  1. Xeon E5-1660 6C/12T CPU @ 3.30 GHz
  2. \n
  3. 32GB DDR3-1600MHz Non-ECC RAM in\n Quad Channel (4x8GB Sticks)
  4. \n
  5. Nvidia Quadro 2000 Graphics (I'm\n assuming this is a K2000 or something along those lines)
  6. \n
  7. A 425W PSU (Apparently 80+ Rated Platinum)
  8. \n
  9. 1 TB Hard Drive
  10. \n
\n\n

Now, I've already made up my mind about the PSU and the Storage situation in this rig, as it stands. The PSU I am definitely throwing out, and swapping in with more rated output to support more recent PCI Cards. As for storage, I'm going to throw in a cheap 512 GB SATA SSD into the mix, as a boot drive as well as a dumping drive for all important projects.

\n\n

This Workstation takes up $400 of my budget (including shipping). The PSU I want to swap in will cost around $100 shipped, and the SSD will cost around $100 as well, so I am already $600 USD deep into this video editing rig.

\n\n

Now onto the question at hand, with the remaining budget at hand, I've narrowed my GPU options down to 3 potential candidates, namely the GTX 1070 8GB from Gigabyte, the Sapphire R9 Nano, and the Strix R9 Fury (NON-X). All of these graphics cards come in at the $400 mark, so price isn't an issue here.

\n\n

I'm not too clued up on the ins and outs of video editing and special effects, so I am not sure what features to look out for when selecting a card for this type of use case. But from what I can tell by reading online forum threads, like on Reddit and Tom's Hardware, the AMD Cards suffer a lot when using these programs, as the OpenCL Support just isn't there, as opposed to the OpenCL Support on the GTX 10X Series.

\n\n

I hope I am wrong, and that I have been reading rubbish.

\n\n

My question is this, out of the three GPUs listed above, which is the best GPU to get for this use case and why?

\n\n

If you have any other GPU recommendations, please don't hesitate to suggest them, any help would greatly be appreciated.

\n\n

As always, thanks for viewing!

After watching videos on Youtube from LinusTechTips, HardwareCanucks and JayzTwoCents, I have concluded that the best GPU for this use case would be the GTX 1070 8GB, as it uses CUDA to encode and transcode footage using the OpenCL API. While the AMD cards do support OpenCL and Vulkan support, it just isn't as optimized as Nvidia's offerings at the same price point, meaning that video encoding and just in general editing will take longer when compared to a 10-series Pascal GPU.

\n\n

This also boils down to driver optimization and feature support coming from each respective manufacturer. One thing to note is that Linus used the GTX 980 Ti as the high end Nvidia GPU at the time, so the performance of that card is very similar to a 1070, hence my decision. The GTX 980 Ti essentially mopped the floor with AMD's offerings, no matter how small the gain was over team red.

\n\n

The 1070 also features lower power consumption and better performance when compared to the other 2 AMD cards I talked about in the original post, which is always ideal for any PC, whilst also allowing for some great 1080p gaming, or maybe even 1440p if we are feeling a bit adventurous.

I need a recommendation for a wireless access point (WAP) that can sustain a network with the following features:

\n\n\n\n

I'd be happy to understand which parameters are important to look at when evaluating a router considering the above requirements.

\n", "Title": "High Performance Wireless Access Point for Closed WiFi Network", "Tags": "|wifi|router|", "Answer": "

The \"routers\" that are available via the retail channel are not suitable for high demand type applications. Additionally, you said that you already had a \"router\" that acted as a DHCP server so there's no point in getting another one. All your need is a wireless access point or WAP.

\n\n

I use the Ubiquiti UniFi AC Pro, not only for my clients, but in my home as well. It's one of the best and most reliable WAPs I have used and is priced at around $150 which is comparable to a high end \"retail router.\"

\n\n

\n\n

Key Features

\n\n\n\n

You can get more information as well as a full full datasheet from their website.

\n\n

Solution

\n\n
    \n
  1. Disable the WiFi on your existing retail router
  2. \n
  3. Run a network cable from your router to the location(s) where you want the APs. These are designed to be ceiling or wall mounted. With wireless, the clearer the line of sight the better (this is why table top \"routers\" are sketchy at best).
  4. \n
  5. Using the included software, configure the AP with your SSID, encryption keys, VLAN's etc.
  6. \n
\n\n

Note that without doing a site survey, it's possible you may need more than one AP given what obstructions (i.e. walls, large furniture, RF generating equipment, etc. - WiFi is still subject to the laws of physics).

\n\n

Clients will associate with the WAP and get their IP from the existing \"router\" with DHCP server because in essence all you're doing is \"upgrading\" the cheap WiFi chipset and radio bundled with your router for an \"industrial strength\" one.

\n\n

Personal note... I had this exact WAP support about a dozen guests (including children) at my home with most streaming Netflix, YouTube, Hulu, etc. and they outstripped my Internet bandwidth before this AP got bogged down (the software comes with reporting capabilities).

Intel Pentium n5000 is an SoC (System on Chip) and is an Atom-based processor. You can't compare it with a desktop based or laptop series i5. The right question would be to compare systems as in whole. Specify what notebooks you are comparing and the usage you are looking to do with it.

A notebook with n5000 will feature low-load applications. It consists of burst speed i.e normally it would idle at a clock speed of 1.1 GHz and when required would top to 2.7 GHz.

Unfortunately, while some low-lane SAS HBAs exist (seems to be mostly under the RocketRAID brand, with questionable reviews), the majority are at least x8. Luckily, these cards are electrically compatible with fewer lanes, and the physical fit can be solved in one of several ways:

\n\n\n\n
\n\n

LSI (now Avago, now Broadcom) seems to be the easiest option, especially if second-hand is acceptable, as these are often decommissioned from servers. There is a list of various models, along with a spreadsheet and glossary.

\n\n

For the specific purpose of a card that supports PCIe 3.0, the following options are suitable (non-RAID options picked for simplicity and price):

\n\n\n\n

These cards can then be coupled with a SFF-8643 (not the older SFF-8087) to SATA cable, and can connect up to 8 drives without expanders.

\n\n

Note that the SAS2308 controller apparently does not support x2 and will probably drop to x1 mode when given a x2 slot.

\n\n

The non-LSI-branded cards (especially the IBM ones) can sometimes be flashed with LSI non-RAID (\"IT mode\") firmware for simplicity; there are many guides available for doing so.

I would recommend purchasing a kit of 2x8GB DDR4 RAM (2133mhz or 2400mhz), replacing your existing RAM entirely. If you wanted to go to 32GB, you could purchase a kit of 2x16GB DDR4 RAM as well, although 16GB is more than enough for the typical user. Then just sell your existing RAM kit (2x4GB) locally, online, or save them for another system. The 2x8GB kit should run around $50-60, and then you can sell your existing kit to help offset the cost. The H110m is a 6th/7th gen Intel-compatible motherboard (1151 socket). They are not the easiest to come by, although I have personally purchased three in the last two years. Due to the current low availability of these boards, the cheap cost of RAM, and the wide-availability of RAM, I would recommend purchasing a kit of RAM over a new board, and call it a day.

I'm looking to buy a new phone and I'm in need of an advice. I want something smaller and I have found a 4.6inch Android smartphone which is great for me (Sony Xperia XZ1 Compact). It is all around a good phone but it has a screen resolution of only 1280x720 pixels. For me that's perfectly okay, I even like it because that means better battery life since it has to render much less pixels. But what I'm afraid of is that app or web developers would stop supporting smaller resolutions like this one in near future and I would be left behind with my decent but low-res phone. Because of the low resolution I'm also considering a Sony Xperia XZ1 (not the Compact one) which has 1920x1080 screen resolution but it is a much bigger phone which I really don't like and would like to avoid (on the other hand it's much cheaper only 250 eur vs 350 eur for the Compact, but price is not the priority in this case).

\n\n

And also this is my first Android smartphone (I have Lumia 820 and before that I had Lumia 800) so I don't know how it works in the Play Store with the support of so many different phones. (For example does the developer define a specific devices which are supported and anyone with a different device isn't able to install the app? Or is there a minimum supported resolution defined for each app and phones with a lower resolutions aren't able to install the app?)

Take the two paragraphs below with a grain of salt since I'm not a web or mobile developer - my colleagues are and this is what I managed to remember from talking to them.

As for support in web apps - what websites use are not physical pixels but rather a \"standardized pixel\" which is size in pixels normalized to a standard PPI.

For apps in Play Store - devices list API level (fancier Android version), possibly some hardware requirements (sensors?) and possibly resolution - but this would again be stated using those \"standardized pixels\".

According to the ASUS website, the board only supports a max of 140W so in theory your cooler doesn't need to be any better than that anyways.

\n\n

However, that motherboard doesn't really have the VRMs required for significant and reliable overlocking. You can do it, but the lack of heat sinks on the VRMs and it only being a 4+1 design is likely going to hold you back from getting the most out of your CPU.

I want to buy a new business laptop where I want to install Ubuntu 18.04 as OS with following characteristics:

Have you some recommendations for me? And some experiences, because I read in some articles with driver problems when using a docking station for two external monitors.

\n", "Title": "Recommendation of business laptop with OS Ubuntu 18.04", "Tags": "|laptop|linux|ubuntu|", "Answer": "

Short, spec based recommendation is the Lenovo X390 Carbon.

\n\n

I'm assuming you're in Europe but not the UK, so the price on Lenovo's Irish site is \u20ac1730-1800 (i7, 16GB soldered RAM, 512GB-1TB SSD). Changing keyboard to German, French etc is free. When I checked on the Irish site, a 1TB SSD was only \u20ac30 more than a 512GB and they're giving away a free Moto One Phone :-).

\n\n
\n\n

Super long version, because upgrading to a new Linux based machine (even without the work and touchscreen reqs) is always a dice roll:

\n\n
    \n
  1. Touch Screen, under \u20ac2k
  2. \n
\n\n

There's a number of great touchscreen laptops that are conveniently around \u20ac2k e.g. Dell XPS variants, Lenovo X1 variants, HP Spectre and Envy variants, Huawei Matebook X etc.

\n\n
    \n
  1. Work use case, 2-4 week horizon, Ubuntu 18.04, touch screen and under \u20ac2k
  2. \n
\n\n

Because your livelihood depends on it, you can't afford downtime with installation, driver issues (funtime imo), support communication and returns uzw. However with current support, the touch screen requirement on Linux is limiting. Do I have any experience with touch screen laptops running any version of Ubuntu? Nope. But at least someone else does. Forums show others who have Ubuntu installed on similar Lenovo laptops with/out touchscreens without issues.

\n\n

So you'd like Ubuntu 18.04.02 LTS Hardware Certification. The Hardware Certification is usually based on a manufacturer installed version of Ubuntu rather than a standard Ubuntu, but it is very encouraging nonetheless. Having 18.04 support listed by Lenovo themselves inspires further confidence that you've taken as many steps as you can to mitigate risk.

\n\n

As of now, 18.04.02 LTS hardware certified and touch screen leaves the Lenovo X390 Yoga and X1 Extreme. Under \u20ac2k leaves the X390.

\n\n
    \n
  1. X390 business extras
  2. \n
\n\n

Loads of ports: Thunderbolt 3 and HDMI (next section for dual external monitors), 2 x USB Type A ports, micro SD card slot which can have a SIM slot for LTE.

\n\n

The charger is 65W via USB-C. Less cables, less hassle.

\n\n

The X390 Ubuntu hardware cert lists Wacom in the hardware details. For this kind of money, its nice to doodle in a meeting while pretending to take notes. The pen slots into the machine and automatically charges.

\n\n

Yoga flexibility - laptop, tent, tablet.

\n\n

Thinkpad keyboard.

\n\n

Privacy cover for camera.

\n\n

The only known downsides I can foresee at this point would be the lowish screen brightness at 300 nit and the fingerprint scanner is currently not supported, probably never will be.

\n\n
    \n
  1. My own dual external monitors and docking station experience
  2. \n
\n\n

I'll try not to moan too much...I've had nightmares with proprietary TB3 docks, even on Windows with drivers and BIOS up to date. Almost all I've seen require Windows drivers. Even if those work, you'd have spent nearly \u20ac200 for the chance it might work with some functionality on Linux :-O. I used Windows To Go for automatic BIOS (saved a little Unetbootin time) and driver upgrades. With Bitlocker enabled, that kept privacy invasive corporate IT away.

\n\n

Now I just connect one monitor via HDMI and the other through a generic USB Type C hub into a TB3 port. The hub has another HDMI port for the other monitor, USB ports for peripherals and an Ethernet port. No dongle mess. Am I downgrading the bandwidth of a TB3 port to USB 3.1? Yes. Am I limited to 2 monitors on HD? Yes again but I don't care, because it works on every screen, every time, needs no power supply and cost a fraction of a TB3 dock. A similar setup should work for all/most Linux laptops.

\n\n

You could walk into Saturn/PC World etc during off peak hours with a live 18.04 USB and try any docks/hubs you have access to. Make a deal with the sales rep that you'll buy if dual external monitors work etc.

Server resource not only depends on its user, but also upon which language it was written in.\nFor example a simple PHP Application can run with just < 100 MB of RAM. But a Java application (Spring Boot) requires >200 MB for an sample app.

For roughly calculating the RAM requirements, run the application with just 10 users (drivers or passengers) and note down the difference between the RAM usage when idle vs 10 users & divide by 10. You will get RAM Usage for 1 user. Then multiply it by the number of users.

Per the post subject, is there an x86 computer like this that I can still buy or otherwise acquire in 2019? Used or refurbished is OK as long as it is still reliable. I want a low-cost, low-energy, fanless, small, 80686 (including CMOV instructions, so VIA C7 is OK but VIA C3 is not) or x86-64 computer with at least three SATA ports using normal connectors, as used by 2.5-inch HDDs and SSDs, instead of mSATA to replace some full-size ATX tower computers with fans and using Core 2 and earlier hardware platforms. Ideally, I want to continue using the current installations of Ubuntu 10.04.x LTS for x86-32 from 2011 because it still works for my application so I want to avoid the chore of upgrading the OS only to use a newer computer. The primary market lifetime (correct term?) of x86 motherboards is frustratingly short for someone like me who still does not have a newer than Core 2 era x86 computer in 2019 because the Core 2 era and earlier x86 computers I use still suffice for my application. I use the same computer hardware until the hardware, such as through-hole electrolytic capacitors, fails. I have found some small, such as Mini-ITX, motherboards with at least three SATA ports using normal connectors but they seem to no longer be for sale by the time I find them, years after they were released. For example, here is a fanless AMD x86-64 Mini-ITX motherboard with six SATA ports using normal connectors:

\n

https://www.asus.com/Motherboards/C60M1I/

\n

Unfortunately, I cannot find anywhere that still sells this model. The hardware does not need to be current; the computers I want to replace use hardware platforms aged at least a decade. I really want to avoid the chore of upgrading the OS only to use a newer computer but I can try to upgrade the OS if necessary or maybe only retrofit a build of a newer than 2.6.32.x Linux kernel into the current installation of Ubuntu 10.04.x LTS from 2011. I think even a Pentium II computer will suffice for my application if it meets the SATA requirements. I need one Ethernet port, preferably (at least) Gigabit Ethernet; Fast Ethernet is the minimum. I prefer Intel over Realtek for Ethernet controllers but Realtek should suffice as long as it is reliable. I live in Canada. On NewEgg.ca , I can filter Mini-ITX motherboards to only those with at least three SATA ports, which eliminates all but two models. One of these models was eliminated because it costs over 1 000 CAD and I do not remember why the other model was eliminated. On Amazon.ca , I can narrow down motherboards to Mini-ITX but cannot filter the results by cooling type (fanless) nor by number of SATA ports. It seems that most models of Mini-ITX and smaller x86 motherboards only have up to two SATA ports using normal connectors. Some motherboards may have at least three SATA ports including mSATA sockets but the drives I am currently using are 2.5-inch or larger and I want to continue using them instead of having to buy mSATA drives. I bought 2.5-inch SATA SSDs instead of mSATA SSDs because I bought the drives for use with microATX or larger motherboards that use normal SATA connectors instead of mSATA; I thought it was better to reduce the number of connectors required to connect the drive to the motherboard to reduce long-term reliability problems caused by connectors than to have more modularity/interchangeability by using mSATA drives. As for the definition of \u201csmall\u201d, I want microATX at the largest. As for \u201clow cost\u201d, I am used to paying <=15 CAD for an Intel Core 2 Duo E8400 CPU and around 50 CAD for a used or refurbished Socket T AKA LGA775 motherboard when I buy five of the same model of motherboard at once. Yes, I realise that these computers have fans but I am trying to give an idea of what I mean by \u201clow cost\u201d. Anyway, Amazon has too many models of Mini-ITX motherboards to go through them one by one to see if any are fanless and have at least three SATA ports using normal connectors. I did find this Core 2 era Mini-ITX motherboard with four SATA ports using normal connectors but I do not know if it is feasible to use this motherboard without any fan?

\n

Edit #1: I prefer to buy x86-64 hardware in case I later need to use an x86-64 OS but, because I am currently using an x86-32 OS, I can still use an 80686 computer with CMOV instructions.

\n

I searched this database of single-board computers for x86 computers with SATA connectivity:

\n

but the only computers with at least three SATA ports looks like they will cost far too much and, regardless, they are overkill for my application.

I ended up buying five fanless AMD APU-based Mini-ITX x86-64 motherboards on eBay: three of the Asus C60M1-I because that was all the seller had then one Asus E35M1-I and one Asus E35M1-I DeLuxe. These models of motherboards are from around 2011, still support legacy boot even though they use EFI instead of BIOS, and the r8169 driver for Realtek Gigabit Ethernet controllers in the Debian/Ubuntu releases from around 2011 to 2013 seems to work well with the Gigabit Ethernet controllers integrated on the motherboards. I am still using the same OS installations on the same physical SATA SSDs but, with a single order from Mini-Box.com, I used the picoPSU to eliminate the fans in the power supplies and used the M350 enclosure to shrink the chasses from full-size ATX to Mini-ITX, only 2.5 litres per computer except for the external AC adapter for the picoPSU and one of the computers has the third SATA SSD sticking out with the top of the chassis not installed because this model of chassis is only designed for one or two 2.5-inch drives so the third drive does not fit normally in the chassis. I placed the order on 2023\u201108\u201115 for six of the ENC\u2011M350\u2011PWR (M350 Enclosure with PicoPSU-80W and 60W adapter kit) at 79 USD each = 474 USD; six of the M350 HDD bracket for mounting a second 2.5-inch drive in the M350 enclosure at 2.79 USD each = 16.74 USD; and six of the \u201cP4-POWER-MINI-Barracuda\u201d \u201cP4\u201d Mini Power Cable for PicoPSU-80 at 1.35 USD each = 8.10 USD and with quotation marks because calling this cable a P4 as in Pentium 4 cable is both an anachronism and a misnomer because it is simply the 4-pin 12-volt CPU power cable for ATX12V motherboards covering many more generations and varieties of hardware than Pentium 4. Anyway, the subtotal is 498.84 USD plus 78.47 USD for DHL to deliver the single large parcel from Mini-Box.com in Fremont, California to me in Delta, British Columbia = total price 577.31 USD converted to CAD because I have a Canadian credit card account. This solution still works well since I assembled the Mini-ITX computers in the summer. I chose the 80-watt picoPSU board because apparently only the 80-watt model has the connector for the 4-pin 12-volt CPU power cable that is needed for the Mini-ITX motherboards I am using. The M350 enclosure/chassis has a black plastic cover for the front to hide a SSD or other USB device connected to the front USB connectors and presumably to dampen the light from the supernova blue LEDs on the front of the enclosure but I did not install these covers because they seem unnecessary. Even though all five of the Mini-ITX computers are on the desktop as in furniture in my bedroom, I can still sleep with the room lit by all of the supernova blue LEDs on the front of the enclosures but some persons may dislike all of this light at night. This model of enclosure does not have a reset switch nor a drive activity indicator light but I guess someone who is into hardware hacking more than me and wants these hardware features could add their own switch and LED to connect to the headers on the motherboard. I will try to add before and after photographs after posting this answer. Edit: I lost motivation to follow through on adding before and after photographs even though I already have photographs from months ago that I could use.

The only notable difference between the two variants is the amount of VRAM

\n\n

It's always nice to have the exta buffer, so I'd say go for the 8gb card, but if money is tight, there is nothing wrong with choosing the 4gb card. The only time it will really come into play is if you want to play a game, or run a simulation that is extremely demanding, i.e. that uses more than 4gb of VRAM.

\n\n

I myself have a 4gb and a 8gb card, and the amount of games that are affected by the difference is very little. All three of these cards will however be bottlenecked, but not a lot. So I'd say for future proofing, go for the 8gb variant!

Reason: I'm beginning to get minor pains in the forefinger and middle finger of each hand. (I swap hands frequently as soon as I feel any pain from one hand.)

I've discovered that if I use a STRAIGHT finger (rather than a curved finger) to press a button, the pain almost disappears in any hand.

Normally, my finger would contact the mouse on the TIP of the finger. But if I use a straight finger, I'm touching the button with the pad of my finger, very close to the first joint nearest the fingertip. So, my straight finger actually overhangs the front of the mouse, by about 1cm.

For now I need to replace the current hard-drive because I heard some loud clicking this morning. I am not in a position to upgrade my full PC.

\n\n

My idea is to get the best storage I can with the aim of transferring it to an updated PC next year sometime.

\n\n

For this reason, I am not worried about whether the (discontinued Intel DH61WW, ca. 2011) motherboard bottlenecks performance, etc as long as I can move whatever I buy into a modern Desktop later on (which would then be able to make full use of the NVMe SSD).

\n\n

I have tried looking into whether there is support. But I am having difficulty understanding whether an M.2 slot is required, or if a PCI-e 4x slot will suffice. Is it possible to install a converter (from PCI-e to NVME, etc).

\n\n

This is what I am looking into atm. How does one find out whether I have what is needed to support it?

\n", "Title": "Does Intel DH61WW motherboard support NVME in any form? Which is the fastest storage it can make use of?", "Tags": "|desktop|ssd|pcie|compatibility|", "Answer": "

The SSD you linked is an M.2 SSD. In order to connect it to a computer without an M.2 slot, you would need to purchase an M.2 to PCIe adapter card.

\n\n

However, given that you're planning to use the SSD to replace your failing hard drive, I'm assuming that you want to use it as a boot device. To my knowledge, NVMe drives are only supported as boot devices on Haswell CPUs or later, and even then, support is very patchy (M.2/NVMe support has only really become stable and standard in the last couple of generations of CPUs). Your motherboard has a LGA1155 socket and H61 chipset, which indicates that you have a Sandy Bridge processor. Additionally, the H61 chipset is the most basic chipset for this generation, and as such would not incorporate any new, experimental or upcoming features. Therefore, it is almost certain that your motherboard will not support an NVMe device for booting.

\n\n

Although it might be possible to use the NVMe SSD as a secondary drive, I suspect that you will run into many technical issues along the way which may render the SSD incompatiable with your system. I wouldn't recommend going down this route.

\n\n

Instead of buying an NVMe SSD, I would recommend simply getting a standard 2.5\" SATA SSD. The speed difference between a SATA and NVMe SSD is usually not noticable during general use, and only really makes a difference if you are using the drive for read/write heavy workloads (e.g. as a scratch disk for video editing). The money saved from buying a SATA drive would also allow you to buy more storage for the same price. Finally, you are unlikely to run into any compatiability issues with SATA, whilst an NVMe SSD is almost certain to give you grief on older systems.

I've got a low-end laptop (a Dell Inspiron, running Ubuntu) which satisfies 95% of my needs perfectly. It's not just that I like and it happens to be low-end; I like it because it's low-end. I like that it's light and thin, and that I don't have to be too paranoid about spilling tea over it.

However, now and then I like to play video games; in particular, I really like Crusader King II. I tried installing this on my laptop, but it runs like ice-cold molasses, unplayably slow.

Generally a laptop can only have one CPU. So unfortunately there is nothing that can be done on that side.

\n\n

For the graphics card it may be possible to upgrade to a desktop GPU using a Thunderbolt GPU Enclosure. This type of device requires a Thunderbolt connection on the laptop. The GPU will only output video to its own connectors so a separate monitor is almost always required. Lastly, these devices don't normally specify Linux support so you may need to figure it out on your own.

I would like to put two SSD drives into my T110 II and have two 3.5\" bays free. I have read in various places that the T110 II doesn't support SSD natively, but I also have a PERC H200 controller with two conventional drives attached, and I have also read in a few places that this should work. All I need is a 2.5\" to 3.5\" adapter.

\n\n

When I e-mailed Dell to ask for a part number they told me that I can't fit SSD into my configuration, so now I don't know where I stand. They have been unhelpful and unforthcoming, and won't give me the part number I've asked for. They just repeat that it isn't supported and so don't do it.

Ctrl+C at boot-up to start the PERC H200 Config Utility and selected the drives in RAID 1 formation. It took nearly 24 hours to complete initialisation, but I discovered that I could actually use the drives during that time. They work perfectly, so yah boo sucks to Dell for bad (wrong) information. I have challenged them on this but they have not replied (no surprise there).

So I have a TV in my room I'd like to able to use to remotely connect to my gaming PC from, but I am trying to find a solution for this that wont cost much.

\n\n

For context, I have the TV and PS4 in my room because they are both super quiet and dont interfere with my sleep. The gaming PC I keep in the office (just a room away) since the LED's and fan noise sometimes disturb my sleep, and I have a different setup for office use (coursework, game dev, etc).

\n\n

Basically, instead of buying a whole new gaming PC for the bedroom, I want to have a means to connect to it, play games, and use peripherals such as my PS4 controller/a Vive HMD without having them directly connected. All while running as quietly as a PS4 while in use, and totally silent when not in use.

\n\n

Now to the r/computerbuilding aspect.

\n\n

Ive thought of a couple options for how to make this work, but I want to explore some of the options more and see what would really be best before dedicating to a build.

\n\n

1) Smart TV My current TV doesnt have any wifi functionality so ive considered buying a smart 4k tv 55\" (same dimensions as the current one). Costwise this is probably around the middle, id imagine a cost of 600 to 700 $, however id be upgrading to 4K as well. My concerns with this are that I dont think there is any way to actually control the PC (except maybe using CEC with the tv remote) unless I pair this with a thin client.

\n\n

2) Thin Client This would probably be very low cost compared to other solutions (200 or under), but I have little experience with thin clients. It seems since they dont use RAM or an HDD they run their own unique OS. So it seems it could be a bit more complex than using RDP from a Windows thick client. Also concerned that there may not be enough ports for USB peripherals, or that it could handle processing 4k/VR.

\n\n

3) Thick Client This would maybe run somewhere in the middle of the road but could potentially end up costing as much as #1. Maybe I am misunderstanding what a thick client is, but by my definition it is a low spec PC (has RAM and HDD vs the thin client) that can offer functionality itself (like running Windows and a browser/low usage apps on its own), but would primarily rely on the server (for my purposes likely via RDC) to offload the heavy processing. I like this option because I have more control and options for what hardware I use, specifically with more ports on the mobo), but I am used to doing ATX factor builds. Problem is, I am not sure I can make this small enough (would have to be smaller than MicroATX probably), cheap enough (ideally under 300$), and quiet enough (dont have experience with fanless/minimal fan builds) to be practical. I also expect a PS4 controller would probably work over RDC but I am less confident if a Vive would also work under this setup.

\n\n

So right now I am leaning towards 2 or 3 (I dont have pressing need for a TV upgrade), but I am a bit on the fence since this is somewhat unfamiliar territory for me.

\n\n

Here are some specs for my setups that might be relevant.

\n\n

Bedroom: 55\" SHARP 1080p TV (manufactured something like 2013) PS4 Slim 5 channel speakers w/ sub Input/output audio mixers that mix audio between up to 4 devices, and outputs to 4 devices (the speaker system uses 3 of these lines for fine tuned control of channels)

\n\n

Office: 3x 21\" Dell monitors, wall mounted Crosshair V Formula Z mobo housed in a Level 10 GT Thermaltake chassis AMD FX-8390 (a bit older but good performance for me), watercooled-single radiator ASUS ROG Strix 6GB GDDR5X GTX 1080 32GB (8x4)DDR3 Corsair Ballistix RAM 1000w XFX PSU - 80+ Titanium rated 2TB Samsung 850 Pro 2.5\" SSD 3x 4TB Seagate Barracuda 7200RPM HDDs in Raid 5 for 8TB storage w/ parity (software raid via FlexRaid-T)

\n\n

And for internet 250mbps + 5ghz WiFi, networked w/ a 5-port unmanaged switch in office. Direct ethernet to PS4 and PC. May get a switch for the bedroom as well if more ports would help.

\n\n

Would be interested on hearing some thoughts and opinions on possible setups and which options may work better than others, or even alternatives im not aware of.

\n", "Title": "Looking for solution for gaming via remote desktop", "Tags": "|gaming|networking|remote-control|thin-client|", "Answer": "

First, if you plan on using Windows Remote Desktop you will have the following issues:

\n\n\n\n

There are better remote desktop/streaming solutions available though:

\n\n\n\n

Steam In-Home Streaming requires a device that can run Steam. Android supports it too. You can use Steam to stream any game installed on the server PC, not just games you own on Steam.

\n\n

Your GTX 1080 also makes you a good candidate for using Geforce GameStream, which requires either an Nvidia Shield device or another PC/Android device (using a third-party client). If I recall correctly, Steam In-Home Streaming uses the same GPU features as Geforce GameStream to encode/compress the video, so the video should look nearly the same.

\n\n

On to the hardware recommendation:

\n\n

A low-end PC with HDMI (thick client) would be all you need to experiment with all 3 of those streaming solutions. With low-end hardware you could even go as far as using fanless coolers and simply avoid connecting any LEDs that may bother you.

\n\n

If you want to keep cost down, an Android box should be able to use the new Steam In-Home client for Android. These things can cost as little as $60 and will work with the DualShock 4 controller over bluetooth. Of course an Android smart TV should be able to run this app too.

\n\n

Lastly, I am not aware of any solution to stream VR from one PC to another.

I'd like to ask you what is CPU architecture, in an oversimplified way. I'm learning node.js and recently I saw a code console.log(os.arch()). The result was x64. What does that x means? Thank you!

\n

I'd like to ask you what is CPU architecture, in an oversimplified way.

\n
\n\n

This question isn't relevant to this Stack Exchange community, but I will try answer it before anyone flags or closes this question.

\n\n

A CPU architecture is basically a name for the design of a CPU; If many CPUs support the same features then it can be said that those CPUs share an 'architecture'. It is especially useful to programmers to know that they can write code once that will run on all CPUs that implement that architecture.

\n\n

The os.arch() function will usually return one of these two architectures on a PC:

\n\n\n\n

The 'x' in 'x86' is a sort of wildcard to represent any CPU from a family of CPUs which all shared a similar design & instruction set. One such CPU was the Intel 80486, which is where the '86' comes from. Thus, 'x86' was adopted to refer to CPUs that implement this common architecture.

\n\n

Later on when AMD introduced 64-bit CPUs, they initially called this architecture amd64, but then Intel came up with their own design and soon the 'x64' term was invented to refer to 64-bit CPUs in general.

\n\n

The purpose of the os.arch() function is to identify the CPU architecture that your node application is running on.

While one can technically desolder and re-solder a BGA processor, it would require specialized equipment like a BGA rework station and a lot of skill.

If the machine actually crashes, you won't be able to SSH it in order to reboot it.

\n\n

Since you say this is a server machine, your best guess would be to check how the machine is connected to the power grid. Most would be plugged into a PDU, and many PDUs can be administered socket by socket, so if the machine is unreachable, you can order the PDU to turn off, and then turn back on the specific socket. If the machine is connected directly to an UPS, you'll probably have a less granular control, i.e. you'll be able to turn on and off groups of sockets, but not individual sockets. It's up to you to determine, in this case, if there can be a reserved group just for this server.

\n\n

Once the power is back on, either the server is configured to boot automatically (or you can set this option in the BIOS), or you need to use Wake-on-LAN to force it to turn on. Check with your system administrator about the security aspects of Wake-on-LAN, since in many locations, Wake-on-LAN packets would be blocked by default.

\n\n

If, instead, you're talking not about a hardware server, but a virtual machine, things should be much easier: check the documentation for the virtualization technology that you use in order to know how to force reset a VM.

What should I upgrade ram or SSD? I have a MacBook pro mid 2012 with 500gb hdd hard drive and 4gb ram. I am a mobile app developer by profession. My hard drive is mainly free with 400+ gb free space. So Should I upgrade the ram or change to SSD?

\n", "Title": "Upgrade ram or SSD?", "Tags": "|memory|ssd|", "Answer": "

Considering 4GB Ram for app development (and if not heavily resource intensive app development like games, design, cad, etc requiring more than 4GB) on a 2012 MacBook Pro - upgrading the HDD to a 500GB+ SSD will provide the greater performance. I recommend at-least 500GB so you can keep at-least 30%+ free SSD space to maintain optimal performance. There's an instant performance increase waiting for anyone running an OS on an SSD with less than 30% free space - free up over 30% and enjoy.

\n\n

The performance of SSDs declines after having less than 30% free space due to the way they distribute the read/write operations more effeciently across completely empty blocks rather than fragmented blocks - although you still don't need to defrag SSDs, they automatically re-arrange the data as needed, but with additional data fragment arrangement processes when the free space is too low (even with TRIM enabled to help with deleted/marked-deleted files). This performance drop is even more prominent in near-full HDDs and moving data seeking platter(s) and needle(s) but due to different ways of handling read/write operations for nearly full (more fragmentation prone) drives.

\n\n

For RAM, having enough to run the OS and needs is first priority - to stay away from using the Virtual Memory backup (additional Virtual RAM on the slower HDD/SSD). After this, topping off your speed from the minimum to the maximum supported by your Motherboard+CPU can provide some additional performance but usually not as significant of an increase as switching from HDD to SSD and increasing RAM capacity on a system that constantly relies on Virtual Memory (doesn't have enough RAM to meet your needs). Faster memory speed is more noticeable in specific applications, but many mistaken it to significantly help increase things like FPS in gaming which is more dependent on the CPU and GPU. Often the cost/performance ratio may not be worth the upgrade if you're only increasing the ram speed a few levels up what's supported, but going from the minimum to maximum supported by a Mobo+CPU may still be worthwhile after the storage speed and capacity are taken care of first.

\n\n

TL;DR: Replacing an HDD with an SSD is usually the best way to revive & boost an older system like a 2012 MacBook Pro.

\n\n

Notes: \n-New MacBook Pros have RAM soldered to the motherboard and can't be upgraded without replacing the entire board with the same compatible board with more RAM (rage table flip indeed).

\n\n

-Be sure to check the maximum RAM capacity and speed supported by your motherboard (verify CPU support on the RAM speed too). All 2012 MacBook Pros support up to 16GB Ram.

What exactly difference between Video Capture rate, Frame Rate and Refresh Rate in video processing ?\nCan we change FPS of CPU graphics ie. rate of Frame per second or not? if yes then how ?

\n", "Title": "difference between Video Capture rate , Frame Rate and Refresh Rate in video processing", "Tags": "|video-adapters|video-editing|video-capture|video-game-console|", "Answer": "

Before explaining what's Video Capture rate, let's read what's Refresh Rate and Frame Rate.

\n\n

Refresh rate:

\n\n

Refresh rate represents how many times the actual TV, video display, or projected screen image is completely reconstructed every second. The idea is that the more times the screen is \"refreshed\" every second, the smoother the image is in terms of motion rendering and flicker reduction.

\n\n

In other words, the image looks better the faster the screen can refresh itself. Refresh rates of televisions and other types of video displayed are measured in \"Hz\" (Hertz). For example, a television with a 60hz refresh rate represents a complete reconstruction of the screen image 60 times every second.

\n\n

As a result, this also means that each video frame (in a 30 frame per second signal) is repeated twice every 60th of a second. By looking at the math, one can easily figure out how other frame rates relate to other refresh rates.

\n\n

Frame rate:

\n\n

Remember those cool little flip books where a pad of paper had an image on every page, and when you flipped through the pages quickly, the image would appear to animate and move? This is essentially how video works. Whether digital or old-school film, video is a series of still images that, when viewed in order at a certain speed, give the appearance of motion.

\n\n

https://techsmith-13.wistia.com/medias/bzujp1kl5e?embedType=async&videoFoam=true&videoWidth=640

\n\n

Frame rate is the speed at which those images are shown, or how fast you \u201cflip\u201d through the book and it\u2019s usually expressed as \u201cframes per second,\u201d or FPS. Each image represents a frame, so if a video is captured and played back at 24fps, that means each second of video shows 24 distinct still images. The speed at which they\u2019re shown tricks your brain into perceiving smooth motion.

\n\n

Video Capture rate:

\n\n

Video Capture rate is just on how many FPS (Frames Per Second) the video will be captured/recorded. As we read above, with more FPS the video stay smoother, and with less FPS, it stays more \"laggy\".

\n\n

Now let's talk about

\n\n

GPU Frame rate:

\n\n

FPS can easily change while you're using the computer. Heavy tasks like playing games can decrease your Frame Rate, while just using your Browser it's almost not going to change your Frame Rate (FPS).

\n\n

Higher resolutions decrease Frame Rate (FPS), since the image to load is heavier.

\n\n

There are many ways of increasing your FPS, I suggest this website.

\n\n

Related:

\n\n
\n

How is the frame capture rate and Refresh rate depends upon each other?

\n
\n\n

Remember that FPS is how many frames your computer is producing or drawing, while the refresh rate is how many times the monitor is refreshing the image on the screen. The refresh rate (Hz) of your monitor does not affect the frame rate (FPS) your GPU will be outputting. However, if your FPS is higher than your refresh rate, your display will not be able to display all of the frames your computer is producing, so although the refresh rate doesn\u2019t technically limit the frame rate, it does effectively set a cap.

\n\n
\n

If I have 60Hz monitor then how much fps Video Capture card needed so that I don't want to loose any frame while capturing through video?

\n
\n\n

As we read above, the refresh rate (Hz) doesn't really matter if we're speaking about frame rate (FPS), so just record your video at 60 FPS and it's all set.

It is supposed to be this way.

Those jumper pins are not used to be connected to something. Instead, you use jumper shunts to connect the pins together. A jumper shunt, by the way, is this thing that you can see on many motherboards, or on all old IDE hard disk drives:

\n\n

\"enter

\n\n

The goal is to be able to specify a bunch of options, such as slowing the transfer rate down, or, in the case of IDE drives, it was used to distinguish between the master and the slave. The exact use of those jumpers depends on the manufacturer and the model. In the case of Seagate Momentus 5400.6:

If the host system does not support SATA 3Gb/s operation, place a jumper on pins 1 and 2 to limit the drive to 1.5Gb/s operation.

\n\n

It doesn't tell what would happen if you put a jumper shunt on pins 2 and 3, or 3 and 4, or put two jumpers together.

Notice that the manual tells explicitly on page 2 that:

I have a bunch of 5V devices (Raspberry Pi and Arduino devices, and LED strips) that need a power supply. I'm currently using a bunch of transformers from BTF Lighting (the ones shown on the image below, not the black ones) which work well, but have one major caveat: they all consume four to five watts of power, even when not powering anything at all.

\n\n

\"enter

\n\n

When the number of those devices is limited, this is not a big deal. However, as I do more and more \u201csmart home\u201d-type projects, 5W multiplied by the number of transformers remaining on permanently starts to be problematic.

\n\n

Ordinary phone USB chargers have a consumption of less than 0.1W when not powering anything. I would be glad to use them, but they are mostly rated 2A or 3A. This is perfectly fine if I need to power a Raspberry Pi, but not OK for a LED strip (5V, 4A transformers from BTF Lighting were heating a lot when used with one strip + Raspberry Pi + Arduino, so I'm relying on 5V, 12A transformers, or on 20A transformers when needed).

\n\n

So, where can I find a transformer which would match the following requirements?

\n\n
    \n
  1. Be as energy efficient as the high quality USB phone chargers.
  2. \n
  3. Have the same format as the transformers on the image above (i.e. screw connectors).
  4. \n
  5. Have 5V 12A and 5V 20A variants.
  6. \n
  7. Include over-voltage protection and short-circuit protection.
  8. \n
  9. Cost less than $40.

Except for #2 a standard ATX power supply for a PC. If you can find a small PCB with screw adapters, you can cut off the molex/sata end solder them to the PCB. Short the 2 pins together on the ATX 20/24 pin plug and you have power.

I know this adapter is $10 + $3 shipping and handling, but it works with any ATX PSU.\n\"enter

There are many kind of LED strips, however, if you work with Raspberry (or any MCU), I guess you want to use addressable led strips (like WS2811, WS2812, WS2813).

\n\n

The reason is that you can switch on the Red/Green/Blue color of each LED separately.

\n\n

If you don't want that, use non addressable LED strips (of course these are cheaper).

\n\n

The difference between WS2811, WS2812, WS2813 is (among others) the fact that if one LED is broken, the remainder of the strip still works.

\n\n

Also there are LED strips who can handle water/liquid slightly better (for outdoor use).

I am trying to spec a rack mountable server to power 5 large screens, each of which will use HDMI to connect to the server.

\n\n

The screens will be used in an IT Operations room and will be displaying browser based dashboards via grafana, nagios etc, so the IT technicians can monitor the environment.

\n\n

The resolution needs to be good enough to read small text, charts and graphs. There is no strict requirement for 4k , although if possible within the budget, 4k would be great.

My budget is between \u00a31000 to \u00a31400 GBP ($1200 to $1650 USD.)

Ideally the server would be a Windows server, although *nix will be acceptable if it is right for the task.

Actually, pricing is one of the least important things to check for a company.

\n\n

What is more important, and what can influence your manager much better, is to write down, what it SAVES when you have faster/better computers.

\n\n

Example: Assume to compiler a full build takes 30 minutes on a slow computer and 10 minutes on a fast computer. This saves the developer approximately 10 minutes (assuming he cannot do much useful stuff in the mean time). Assuming a salary of 50 dollars/hr, saving ten minutes saves 50 * (20/60) = 16.67 dollars.

\n\n

Assume you do 10 builds per week, it saves 167 dollar per week. \nWhen the faster computer cost 1000 dollars more, after 1000/167 = 6 weeks, the computer is paid back.

\n\n

The complication is that sometimes it's hard to calculate (what if your manager says you can do something useful in the waiting time? Probably you have context switching time loss etc).

\n\n

But in general, if the faster computer can saves you considerable time, the salary losses outweighs the cost of a computer by far.

It is possible that a few specific CPU models are still being manufactured at the request of a significant customer or for providing long-term support.

\n\n
\n

does this mean that at some point in time, that specific company (Advantech) bought an over abundance of these processor and now they are continuing to sell these industrial PCs until they run out?

\n
\n\n

That is a valid explanation if you see that it is \"Discontinued\" on the website; Most socketed CPUs from the 4th generation are, and the ones that still say \"Launched\" are almost entirely CPUs that would never have been sold in a retail box or stand-alone. (They are mobile CPUs to be installed by an OEM.)

\n\n
\n

Does this mean that they are selling Intel processor that are past the life cycle and a different hardware industrial PC should be selected?

\n
\n\n

I would look for newer hardware anyways, especially for a fanless system since the newer generation chips use less power to provide the same (or better) performance.

I'm search for a monitor that can handle an input signal of 4k at 60fps, over its HDMI input.

\n\n

I've found the Dell Ultrasharp U3219Q that have a HDMI port. As you can see in its online manual, page 14 in the table :

\n\n
\n

Ports and connectors : 1 x DisplayPort version 1.4 (HDCP 2.2)\u2022 1 x HDMI port version 2.0 (HDCP 2.2)

\n\n

So, this is an HDMI 2.0 input port, but it doesn't support HDMI 2.0 specification ? What am I supposed to understand there ?

Can the HDMI input of the Dell monitor U3219Q handle a 4k@60fps input signal?

Yes.

The footnotes on that page of the manual can be rephrased like this:

\n

Supports HDMI 2.0, but without optional specifications ... such as 4K digital cinema resolution (4096 x 2160).

\n
\n\n

If you look at the page right above \"Electrical Specifications\" you can see that the monitor does support 3840 x 2160 @ 60hz as long as the video device supports HDMI 2.0.

And another note on 4K terminology:

\n\n

3840 x 2160 and 4096 x 2160 are both casually called \"4K\" but to avoid ambiguity the former is referred to as \"UHD\". The Digital Cinema Initiatives (DCI) have used \"4K\" for their 4096 x 2160 resolution too, so it is more specific to refer to that as \"DCI 4K\" or \"Cinematic 4K\", which is what Dell has done in your manual.

I am Currently Looking for a Thermal Camera which either has an lcd screen which can be be extended away from the camera or simply a high quality thermal camera which can be programed into an lcd.

AMG8833 is a popular thermal camera which has an accuracy of 2.5 \u00b0C (4.5 \u00b0F). The benefit is that it's commonly used, and has a pretty decent support. The drawback is its tiny resolution, 8\u00d78 pixels only. It costs around $40.

\n\n

MLX90640 is another, although less popular, choice, with its increased resolution of 32\u00d724 pixels and an accuracy of 1.5 \u00b0C. You can get it for $70. Using one is more difficult than AMG8833, especially regarding to the hardware requirements:

\n\n
\n

Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno (or equivalent) doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20,000 bytes or more of RAM. To achieve this, we recommend a Teensy 3.1 or above.

\n
\n\n

For $240, you can get Lepton 2.5 thermal camera module which comes with an impressive resolution of 80\u00d760 pixels, but a disappointing accuracy of only 5 \u00b0C.

\n\n

Flir website lists more models, including Lepton 3.5 camera core with its 50 mK thermal sensitivity (the same as 2.5 version) and a resolution of 160\u00d7120 pixels. The camera core seems to be sold for about $270, but I can't find it in a form of a module to be used with Raspberry Pi.

\n\n

Or you get more specialized models such as Neutrino SX12 with a sensitivity of 25 mK and a resolution of 1280\u00d71024 pixels. You'll need something other than a Raspberry Pi to power that thing. I can't find its price, but I won't be surprised to find that you have to pay more than a thousand dollars for a device like that.

\n", "Title": "Single-band, 5GHz only WiFi router?", "Tags": "|wifi|wireless|router|", "Answer": "

Routers and WiFi devices have to undergo certification to have the \"WiFi\" branding. Any router that does not have a 2.4 Ghz radio would not be backwards compatible with IEEE 802.11 b/g/n and may not qualify for the \"WiFi\" branding.

\n\n

I have never seen a \"WiFi\" router with only a 5 Ghz radio. But you can disable the 2.4 Ghz radio in many routers though. It is possible that a router with only 802.11ac support can exist, but it may be hard to find a product like that using the \"WiFi\" brand as a search term.

\n\n

For now, I would not recommend seeking out a product that explicitly avoids having a 2.4 Ghz radio. It wouldn't be guaranteed to work with other WiFi devices unless it was WiFi certified too. Some day the WiFi Alliance may decide to deprecate the 2.4 Ghz standards and this answer may no longer be correct.

An 8-bit display can use FRC to expand its perceived color range. It essentially dithers a pixel between two colors in time rather than with neighboring pixels.

Many monitors do this, in fact a lot of displays that support \"16.7 Million Colors\" (24-bit Color) are actually 6-bit panels using FRC.

If you are trying to decide between monitors, I wouldn't let this detail become a deciding factor. You are very likely looking at a monitor right now that uses FRC and you may not have noticed.

\n", "Title": "CPU for Machine Learning", "Tags": "|processor|motherboard|", "Answer": "

Two assumptions first:

\n\n\n\n

In the current market and in your budget you will likely not be able to get a better CPU.

\n\n

The Ryzen 9 3950X is supposed to come out soon but it is supposed to be 50% more expensive by MSRPs from the launch event. Counting by retail prices in my country (Poland) this will put the X570-A PRO + 3950X at around 1150 USD. Of course the price might be different in different countries.

\n\n

Another option is to invest that money in the overall build quality, primarily the motherboard and cooling, and try to eke out more performance but the returns here are minimal.

\n\n

Personally, if you are unable to stretch your budget or wait for the 3950X, I would spend maybe 50$ on a bit better motherboard and keep the rest for the next GPU upgrade.

\n\n

Edit: I don't know much about the data transfer patterns in ML vs games, but ML uses much more memory so it might benefit greatly from PCIe 4.0 once next-gen GPUs implement it

Many of them are actually standalone devices that render their own output from a video file or website, and do not always support direct video input. Make sure you any model you are interested in does have a video input.

Intel Quick Sync is only available from Intel's integrated graphics. If you're using integrated graphics you probably already have this feature. Make sure you have the latest drivers installed for your motherboard and integrated graphics. Your motherboard supports something called \"Lucid Virtu\" which allows a dedicated graphics card and integrated Intel graphics to appear as a single GPU to the OS. This feature should be disabled (in BIOS if possible) and the drivers for \"LucidLogix\" or \"Lucid\" should be uninstalled. It is possible that they can interfere with the Quick Sync feature.

\n\n
\n\n

NVidia NVENC was introduced on the GeForce 600-series. That was several years ago and at this point, almost every NVidia card except the cheapest models have the NVENC feature. You can buy pretty much any \"gaming\" tier GeForce you'd like.

\n\n
\n\n

AMD VCE was introduced in the Radeon 7000-series, which is also several years old. Practically all of AMD's GPUs since then support VCE. Once again, you may buy pretty much any \"gaming\" tier Radeon card you want.

\n\n
\n\n

Lastly, you don't actually need any of these features to record your screen. Before these hardware-accelerated features existed you could use software like FRAPS. These days I would recommend OBS Studio, which is much newer and open source. It doesn't need the hardware features but it can use them if you have it.

Which machine is a better choice for running VM, virtual labs, coding & studying?

\n
\n\n

Aside from the CPUs, there are several attributes of the laptop models themselves (size, weight, shape, screen, keyboard, etc.) that you will need to personally weigh into your decision. I can't objectively say which machine is better for you, but at least we can objectively compare the CPUs in question.

\n\n

According to user-submitted benchmarks, the i7-3520M is only 10% faster than the i5-5300U on average.

\n\n

The i7-3520M CPU was a high-end CPU from 2013 intended for gaming laptops and mobile workstations when it released. In 2013 it would have been one of the best choices for your kind of workload.

\n\n
\n

I read that the U series of CPUs are sluggish comparing with the M series.

\n
\n\n

The i5-5300U CPU is a low-power CPU from 2015 intended for ultra portable (thin & light) laptops that allows long battery life. In 2015 this CPU would not have been suitable for your workload compared to the i7 'M' models available at the time.

\n\n

That doesn't mean that all 'U' CPUs are worse than all 'M' CPUs though. The age difference between these two CPUs has allowed Intel to close the gap through architectural improvements. If you were to look at a current-gen 'U' CPUs from 2019, you may find one that is faster than the i7-3520M!

\n\n

The i5-5300U being a newer CPU gives you some advantages over the i7-3520M that are worth trading the 10% advantage for:

\n\n\n\n

If none of the points above appeal to you, then the i7-3520M is still a faster CPU in terms of raw performance.

I want to upgrade my laptop to have an external GPU. What's the state of things in late 2019?

\n\n

I would prefer not to remove my WiFi card.

\n\n

Does such a thing exist for USB-C as well? My laptop has a USB-C port without support for Thunderbolt 3 and with reduced Bandwidth of around 5 Gbit/s. It also has a free USB 3.0 port. What's the optimal solution for me?

\n

What's the state of things in late 2019?

\n
\n\n

There are currently two ways to install an external GPU to a laptop.

\n\n\n\n

In the near future USB 4.0 will incorporate the Thunderbolt 3 protocol. This will likely cause the current Thunderbolt 3 enclosures to be supported by a large number of laptops with USB 4.0 support.

\n\n
\n

Does such a thing exist for USB-C as well?

\n
\n\n

No and yes.

\n\n

\"USB-C\" is a specification supporting USB 3.x. There is no support for exposing PCI express through USB-C.

\n\n

Thunderbolt 3 is an entirely separate specification that supports USB 3.x and PCI express. It also uses the USB-C connector but the port is considered a \"Thunderbolt\" port, not \"USB\". Thunderbolt devices usually require a superior quality cable too.

\n\n
\n

What's the optimal solution for me?

\n
\n\n

It looks like the adapter you linked might work with the WiFi slot, but it will be significantly slower than a Thunderbolt 3 connection, and may bottleneck the GPU. If your laptop is new enough you might need to use an M.2 version of a kit like that, since many WiFi cards come in an M.2 slot now.

\"enter

\n", "Title": "What is the difference between \"M.2 PCIe NVMe\" and \"M.2 2280, PCIe-NVMe, TLC\"", "Tags": "|ssd|", "Answer": "

Repeating comments as an answer.

\n\n

2280 is the size designation for an M.2 card, such as an SSD. This is the typical size for a PC.

\n\n

TLC is the type of memory used in the drive. It stands for Three Level Cell which means that each cell holds three bits. This is again typical for a consumer drive. MLCs, with two bits per cell, are used in high-end drives like the Samsung Pro series, while QLC, with four bits, are used in low-end drives like the Intel 660p.

\n\n

While this is likely a duplicate entry, but personally I would pick the one with more details, otherwise you could get a terribly overpriced Intel 660p.

\n\n

If that price is in USD the drive is expensive anyways - if you can and are able to put in the drive yourself, get something like the Kingston A2000 which has a suggested price of 99 USD for a 1 TB model. It should be good enough for any non professional uses.

I have wanted to set up a NAS for ages. I recently moved house and had to buy a new fibre modem/router. It has two USB 3.0 ports, and it'll be switched on all the time, so I figured it might be a low cost, low power way to get my NAS going.

This depends on the dual-bay enclosure that you buy, but most of them appear to the computer as a USB hub with either one or two USB storage class devices attached to it.

\n\n

With the enclosure that I have used before (Mediasonic ProRaid), there is a physical switch to select how the disks are used. When it is in RAID 0 or 1 mode, the PC can only see one drive which is the virtual disk created by the RAID. I have tested this enclosure with multiple operating systems and it seems to work as a plug & play USB drive, like any other USB hard drive or stick would.

\n\n

Since your router does support USB storage, I expect that most USB RAID 1 enclosures will be detected by the router as a single drive.

I'm going to build a computer, but I'm stuck on choosing a processor. I found two processors: Intel Core i7-9700K and i7-9750H. The 9750H, according to the official site, is a bit faster and has more threads. But, on Intel's website it's marked as Mobile. Does that mean it's incompatible or it's not recommended to use it in a desktop computer? If that's the case, can 9700K fill up like everything from gaming through 3D animation to programming?

\n", "Title": "Intel Core i7-9700K vs 9750H", "Tags": "|processor|intel|", "Answer": "

The 9750H is a mobile processor, meant to be soldered to a laptop motherboard. It will not fit in a a desktop motherboard, nor will you be able to buy one. So for a desktop you don't have a choice. Unless you buy a notebook.

\n\n

That said, why would you buy the 9700K now? According to benchmarks the cheaper Ryzen 7 3700X is slightly slower in some tasks (single or light threading), but can be significantly faster in others (heavily threaded).

\n\n

That said, what you mostly care about, both for games and 3D is single core performance and the GPU. Games tend to be lightly threaded, same as mesh editing. For programming it depends on your language, although I suppose build in any language are paralleled nowadays. Autocompletion in the IDE is more of a single thread stuff as well.

\n\n

As a side note - you definitely want an RTX. With both Blender and V-Ray supporting RTX it's a no-brainer as long as you have the budget. I've seen benchmarks where Blender render times were cut in half using hardware RT vs pure CUDA on the same card.

Judging reliability of an SSD that hit the market less than a year ago is kind of difficult. And the actual question here (can I trust brand X) is much too broad to be answered conclusively. Patriot sells lots of different SKUs, at different price points, and for a different target audience.

\n\n

While it mostly performs on par with similarly priced SSDs, It's biggest weakness is that it is a DRAM-less SSD. Which is why it struggles with intensive random read/write workloads. To a point where the difference becomes noticeable, even in real-world applications.\nIf we take a look at the prices for the 500GB model, the difference between the P200 and for example a Crucial MX500 is only about 3\u20ac in my part of the world. Add another 8\u20ac, and you can already afford a Samsung 860 Evo.\nIn my personal opinion, the minimal price difference is not worth the potential performance difference for your applications.

tl;dr: invest a little bit more, and get different SSD with DRAM cache

Based on benchmarks it seems that if you are going to purchase a 2070, it only costs a little more for a somewhat noticeable difference. The 2080 is not that much better than the 2070S, however; the 2080S benches about 16% higher than the 2070S, and whose performance would be noticeably different.

Upgrade Notes

\n\n

On a different subject, your CPU is not terrible for the setup and will probably not be too much of a bottle neck as most games are GPU bound rather than CPU bound. You might be able to achieve slightly better performance with a newer top of the line CPU, but an upgrade like this would likely be of higher benefit if you are doing heavy multi-cooperative computation or heavy video processing/encoding.

So I have tried the foscam brand, but found that they have the you figure it out approach to setup. I have never set up a tabletop indoor security camera before and found foscam to be a pain. There was something about using some IP, but was never sure if it was the IP of my router. If it was the IP of the camera, then tough because I had no clue what it was or where it was.

Thanks.

\n", "Title": "Hardware upgrade path for high gaming resolution", "Tags": "|graphics-cards|processor|motherboard|", "Answer": "

If you're going to upgrade something on that system, upgrade the GPU. Even the fastest CPU your mainboard supports (an i7-3770K) is only 50% faster in multi-threaded performance, and less than 5% faster in single-threaded performance; the fastest modern CPU is less than 50% better single-threaded, gaining performance mostly by virtue of having 32 cores. In comparison, there's plenty of headroom for improvement in the GPU, and more GPU is what you need to push more pixels.

\n\n

Your existing GPU has a TDP of 120 watts. Since you don't know how much extra capacity your PSU has, I'm going to recommend an upgrade with a comparable TDP: the GeForce GTX 1660 Super, for around $230. Benchmarks give it a performance of 2x to 3x that of your current card, and unlike the GTX 960, reviewers considered it worthwhile to benchmark at resolutions above 1920x1080. Since the card's fairly new, there's not yet much variation between manufacturers, so pick whichever card is cheapest (or looks the best, or whatever minor criterion is important to you).

\n\n

(Another upgrade option, much cheaper, but without much expected benefit, is another 8GB of RAM. The P67 chipset is capable of dual-channel operation, so if you're seeing single-channel, it's because you've only got one stick of memory (likely) or the memory isn't in the correct slots (less likely). Faster memory doesn't give much of a performance boost, though.)

Since the question seems to be mostly about the price difference, and not about technical differences between the two generations of CPUs, I will limit my answer to the former.\nSomewhere between these two generations of Intel CPUs, AMD happended. Their Threadripper CPUs and Ryzen CPUs with high core counts more or less forced retailers to lower their prices for Intel X299 CPUs, particularly the Skylake-X lineup. https://www.tomshardware.com/news/intel-skylake-x-price-cut-cascade-lake-x

\n\n

Then with the current 10th generation of X299 CPUs (e.g. I9-10980XE) Intel lowered MSRP for their CPUs significantly. See https://www.tomshardware.com/news/intel-cascade-lake-x-pricing-availability-launch-specifications-10th-generation,40526.html

\n\n

So don't let the price difference fool you into thinking the older 7th gen CPUs are that much better than current 10th gen Cascade-Lake X CPUs, or 9th gen CPUs. They just did not get the price cuts, because they are too old to be relevant in today's retail market.

Direct Answer:

\n\n

This Access Point has what you are looking for and should work.

\n\n

Recommended:

\n\n

You can use any old access point if you purchase a separate switch. I recommend specifying that it is Gigabit and has the full bandwidth for all ports like this one. Then plug the connection to your router, the PC, and the access point all into the switch in your bedroom.

\n\n

I recommend this route because you can keep the switch for many years to come as you replace your router and AP with newer models.

\n\n

Using a second router:

\n\n

Typically using the WAN port on your router will cause it to act as a Router, Switch, Access Point, NAT, and Firewall. However, you can disable these features and have it act as just an Access Point and Switch. You will need to look through the settings on your router and configure it to do so.

small company (around 20 employees)... small server... access to shared storage and sync outlook tasks/calendars... and maybe do some light processing on it

\n

What sort of specs are recommended for running a Windows Server (mostly for Microsoft Exchange).

\n
\n

my first recommendation would be to talk to your boss, chief information officer, or president (depending on company) because today doing what you are asking is no longer a trivial matter, especially regarding data security, legal requirements, lawsuits, etc. So you don't just want to build any old computer/server and have it wherever. Talk to whoever would be held accountable for such a problem should it arise,

\n

that may then lead to a dedicated server room being made available, having locked door or badged access, where you can set up resources and have it functional and reliable... reusing a nice gaming rig is not professional.

\n

basically... workstations (i.e. your thought of gaming rig) are desktop pc's which will be limited to ~ 64gb or ram and are expected to be used by one person at a time. A server can be the same hardware, but will be in a rack server form factor, hold greater than 64gb of ram, and allow for better networking capability, to allow reliable and better performance to run MS exchange mail server and provide a data share.

\n

you may want to look into NAS - network attached storage, which will be separate disks and hardware to provide data storage which would be separate from an MS exchange server; having one server do everything increases likelihood of everything not working one morning when something fails (and it will) so you have to plan all that out and understand what you actually need vs want vs budget. For however small a company, you just don't throw a gaming rig together to allow the company to do business; if it needs to be "cheap" then you may want to rethink your business strategy. You can find small business servers from DellEMC or HPE, you would call them tell them what you need and they will advise you on the type of hardware to be used, and you can always get refurbished/reconditioned if you are looking for less expensive equipment.

\n", "Title": "USB cable that would mirror USB signals to multiple devices", "Tags": "|usb|cable|splitters|", "Answer": "

No, but there are alternatives

\n\n

Sorry for the short answer, but unfortunately, USB just doesn't work like this. Because of... protocol reasons that we won't dive into here, USB doesn't have anything really resembling this capability. The closest you'll get is a standard hub or KVM.

\n\n

However, what does exist are serial splitters. Since it appears that all you're doing is using a COM port, what you could do is use a USB -> serial adapter, split the serial port into several serial ports, convert the serial back to USB (or whatever you'd like), and proceed to plug those into whatever target computers you're using. If that sounds like one too many adapters, StarTech even the ICUSB2324, a convenient USB to quad serial adapter.

\n\n

However, there's a reason we don't all have USB and serial splitters plugged into our computers. There's almost always a better way of doing things, unless you're working with specialized, legacy hardware. Networking and virtual serial ports exist for a reason, and you're almost certainly better off using one of those. Without more info on your application I can't really say that with 100% certainty, but it's probably true.

M.2 is a form factor, it technically has nothing to do with speed or performance.

\n\n

You can get m.2 storage (to replace your disk or ssd) and this storage can connect either via the SATA3 protocol or NVMe protocol.

\n\n

SATA3 is limited to 6 gbit/sec, which then connects to the PCIe bus.

\n\n

NVMe is a protocol allowing a direct connection to the PCIe bus, it not limited to the 6gbiy/sec transfer rate limitation of the sata3 interface, and is thus faster.

I have a USB-C screen (Lenovo ThinkVision P27H) which I want to connect my laptop to, so that I just need one wire for charging and video.\nThe screen also features a USB hub, which is why I would like to connect my USB mouse and keyboard to the screen, so that I really just need one wire.

Here comes the problem: I want to run a desktop PC with the same screen (but not simultaneously), and this PC also uses the same mouse and keyboard.

\n\n

So, what I'm looking for is a solution that allows me to use my peripheries on both machines without plugging in and out my mouse and keyboard everytime.

\n\n

The screen only features one upstream USB port, which is the USB-C one. My desktop doesn't have a USB-C port.

I thought about something like a USB-C switch, or more like a \"splitter\" (one USB-C in, two USB-C out) that I can connect to the screen. Then I could connect my laptop to this switch, as well as a USB-C to USB-3 adapter to talk to my desktop PC. My hope is that this enables me to use the USB hub of the screen no matter which device I'm currently using.

USB-C KVM

\n\n

The product you're describing does exist... kind of. However, because it's a niche product, there are only really two implementations I'm aware of\u2014both of which are very expensive and don't really do quite what you want.

\n\n

US3310 - $200

\n\n

\"enter

\n\n

Though the exact branding and seller varies, there are at least two (1, 2) identical versions of this hub for sale. It features two switchable USB-C connections (with power passthrough), two USB-A in, one HDMI 1.4 out, and a USB-C power port. Notice the HDMI out: while this will work just fine, you'll have to drive your monitor off HDMI\u2014not USB-C. This means that you won't be able to use the USB hub in the monitor without a second adapter to plug it in to the USB plugs on the front. Eugh.

\n\n

Black Box - $300

\n\n

\"enter

\n\n

Again, we've got two switchable USB-C connections, several USB-A in, and a DisplayPort out. Again, we've got the same issue, where you'd need an adapter to use the hub in the monitor.

\n\n

Standard KVM + Hub

\n\n

Another option to keep the single-cable functionality is just to have your laptop connect to a USB-C hub, which then breaks out into a \"standard\" display interface and USB, then runs into a KVM. Is this discarding one of the key features of your monitor? Yes. Is it cheaper and cleaner than getting a USB-C KVM? Maybe, depends on your idea of cleanliness. But it's almost certainly cheaper. Depending on what specs you end up deciding you want, you can get a hub for about $30 and a KVM for about $40. If you choose to go this route, I can definitely make some more specific suggestions.

\n\n

Software KVM

\n\n

Through the power of networking and software, you could get most of the functionality of these hardware solutions with almost none of the hassle. Using something like Synergy, you can share your mouse and keyboard over the network. However, since this would require the laptop to be plugged in, even when you're using the desktop, I'm going to assume this is probably a no-go. Further, other USB devices aren't shared, so if you wanted to (for example) plug in a USB drive, you wouldn't be able to use the hub.

\n\n

Just buying a different monitor

\n\n

This is probably going to sound really stupid, and in a certain sense, it is. However, it's also probably the cleanest, nicest way to get what you're looking for. Currently, several monitors offer built-in KVMs and USB-C, with convenient switching between them. Are they all more expensive than the P27H? Yes. But will they also offer a lot of other benefits, including greater resolution, size, or color accuracy (depending on the model)? Yes.

\n\n

I won't go too in depth into each monitor right now\u2014again, if you decide this is the right path for you, I'll be happy to help more\u2014but here's a quick overview.

\n", "Title": "small size Alternative of raindrop sensor", "Tags": "|arduino|", "Answer": "

I made a diy flexible sensor for diaper-free time - not exactly what OP asked but still might be helpful. You can make it smaller with thinner tape and sheet but still probably not comfortable/usable within diaper. (Side note: Good diapers actually have wet color-changing strip on them, which is much more practical. You can just replace them every 3-4 hours or look at the strip.)

\n

I used adhesive copper tape (2cm wide) to make the rain sensor-like pattern on top of OHP transparent printing sheet. I also printed out the pattern on OHP sheet to help lay out the tape (visible from back). This makes for a nice large A4-size sensor which is flexible, waterproof and not easy to tear. Then I use 2 alligator clip to attach to 2 rails and connect to mcu. It would be nice to upgrade to a single clip with 2 connectors to make it quicker to detach.

\n

One issue I noticed is that human body resistance can also trigger false positive if you sleep directly on it (think of resistance of skin between two closest fingers of the sensor, not whole body resistance). Rather, I use a super-thin 20GSM hospital/salon-purpose bedsheet which is laid out on the sensor and lay the baby on this bedsheet. Because it's very thin and absorbent, as little as 3 drops of water easily soak to the bottom side and activate the sensor while increasing the non-wet resistance to infinity (beyond multimeter measurement). It's also more comfortable to sleep on.

You get any robust SBC. The handheld scanners already convert the QR code to text so you don't need to worry about vision recognition. It might be easier if your scanner has a virtual COM mode rather then the usual keyboard simulation.

That said, the only issue with Pi's robustness, as far as I'm aware, are power cuts - if you power it off when it's writing to the SD card it might damage the filesystem. And being rated only to work in non-freezing temperatures.

I have a very particular workload that requires GPU (OpenCL mandatory) acceleration.\nHowever, from what I hear, GPU are optimized for floating points computing, where the task I need acceleration for requires a lot of Integer computing, and those Integer computing scores are kinda hard to find.

- 60% of 8 bits unsigned integer, mostly used for performing ADDITIONS (adding random bytes together)

\n", "Title": "Single Board Windows PC with 4K HDMI input and 4K Output", "Tags": "|pc|hdmi|4k|development-board|", "Answer": "

There is no board that fits your exact requirements. Get an add-in capture card.

\n\n

Assuming we allow 4K@30 output, getting 4K out is a pretty simple task since most every board supports HDMI 1.4. Unfortunately, encoding a 4K stream, even at 30 Hz, is an extremely demanding task, and putting that requirement on an SBC makes things... complicated. Let's run through some of the options.

\n\n

x86 boards with video input

\n\n

Intel embed-oriented processors\u2014namely Apollo Lake and Cherry Trail\u2014contain support for the MIPI-CSI interface, and there are a variety of boards with support for these processor lines. However, only a few actually have a the requisite connector on the board. From most to least powerful, they are the UP\u00b2 and PICO-APL3, UP Core Plus, Up Core and ROCK Pi X.

\n\n

Interfacing with the MIPI-CSI port can be accomplished through the use of an HDMI to CSI bridge. Toshiba manufactures three such chips: the TC358743XBG, TC358840XBG, and TC358870XBG, the latter two of which support 3840x2160@30. However, there is no reference or development board available to my knowledge, and the only consumer boards available\u2014the Auvidea B100, B101, and B102\u2014use the TC358743XBG. Additionally, these boards rely on a V4L2 driver to interface properly\u2014something that obviously isn't available on Windows. While it's possible that they'd work just fine with Windows, it's hard to say. Outside of these, you'd be resorting to designing your own board or trolling AliExpress for an appropriate board.

\n\n

Further, Apollo Lake and Cherry Trail processors are... not powerful. I wouldn't trust them to perform a high quality software encode, and given they only have HD Graphics 505 at best, I wouldn't trust them to handle it with Quick Sync Video either.

\n\n

Powerful ARM boards with CSI video input

\n\n

I know you've already discussed it to some extent, but the Jetson does make a fairly compelling case. It's got the most powerful GPU of any SBC I know, and 4K encode with NVENC should be will within reach\u2014and NVENC looks good, even compared to a software encoder. Unfortunately, it's obviously not going to run standard Windows, so unless your application happens to run on Windows 10 on ARM, you'd have to refactor your application. Further, it uses MIPI-CSI for video input, not HDMI, which puts us back in the same situation as the x86 boards where there's (as of yet) no adapter.

\n\n

ARM boards with HDMI video input

\n\n

Similarly, there are a number of boards with HDMI video input. Unfortunately, most of these boards aren't particularly powerful, nor do they support standard desktop Windows, giving us many of the same problems as before.

\n\n\n\n

Powerful x86 boards without video input

\n\n

This is probably the most reasonable option. Given the availability of USB and PCI-e based capture cards, using a capture card with a powerful board would allow for everything to work\u2014just with some extra effort and hardware. Given the widespread availability of this type of SBC (and similar NUCs), I won't attempt to enumerate every possible board. However, using software, Intel's Quick Sync Video, Nvidia's NVENC, or AMD's VCE are all possible depending on which exact hardware you get (though you should note that VCE in particular falls behind the others.) Some manufacturers you may want to look at include Udoo, Up, Aaeon, and Ibase.

I've successfully written and ran a Qt/QML application (albeit with a simple interface) on a custom baseboard for the CM3 running Raspbian Lite without X. Not through framebuffer but using the VC .sos provided for the Pi. If you used framebuffer on the Pi you likely used Qt without hardware acceleration. Qt has a separate QPA backend using VC libraries directly.

\n\n

There are alternatives, but they are usually development kits and SoMs with their carrier boards rather then SBCs. Those are targeted at professionals who design custom devices with such processors.

\n\n

You can for example look at Toradex i.MX 6 Quad SoM which is a Qt reference platform. They have Yocto support too. The SoM with it's carrier board will set you back about 200 euro though.

\n\n

The official i.MX 6Quad Sabre board is 450$. And that's for SoCs which tend to be on the cheaper end of the range for their performance point.

\n\n

Apart from the i.MX there are other series of SoCs which you can look at with their own SoMs and devkits, such as:

\n\n\n\n

The cheapest option would be the BeagleBone Black which is also the only hobbyist/maker board which has a chance of fulfilling your requirements that I know of.

\n\n

Apart from the Pi's BCM2 every other SoC mentioned above has full documentation available (I often compare BCM283x's measly 150 pages to total 6k pages of datasheet+manual of the Sitara SoC found in the Beaglebone).

\n\n

Lastly, there is a lot of maker boards with Allwinner or Rokchip SoCs but those are not fully open AFAIK.

I am not sure I truly understand what these specs mean for a laptop LCD matrix:

\n\n\n\n

Which values are better when picking a screen?

\n", "Title": "Laptop matrix parameters like wide color gamut, white variation, haze?", "Tags": "|laptop|displays|", "Answer": "

Here is a simplified explanation of each specification and their effect:

\n\n

Wide Color Gamut (WCG): This simply is a qualitative measure of the number of colors the LCD display can use as opposed to the standard Rec.709 gamut. This generally means more vibrant colors, as opposed to a standard display. This is because:

\n\n
    \n
  1. The color palette itself bigger.
  2. \n
  3. It uses a higher bit depth (8bit, 10bit, etc.), which signifies how many steps of each color a TV has available.
  4. \n
\n\n

You should use a LCD display with a WCG for a better picture and color fidelity. If this isn't necessary then go for a standard Rec.709 gamut.

\n\n

White variation: It is the difference in luminance of the LCD at different spots of the LCD screen. Refer to this note:\n\"enter

\n\n

Thus, a higher white variation means difference in the white brightness in individual spots of a fixed viewing angle. This should be the lowest possible for visual accuracy.

\n\n

Haze: This refers to Reflective Haze. Haze is the measure of how much reflections are diffused. A higher haze rating usually means an anti-glare coating which is increasingly matte. This generally makes colors less pop out, but with a decrease in reflections. \nHere is a comparison picture of different levels of haze and the effects on reflections and color: \n\"enter

\n\n

Generally, under high ambient light, a higher haze is better for increased readability and visual acuity. If there is little chance of reflections or no ambient light is needed, then the haze percentage doesn't need a higher than 25%, which increases apparent color accuracy.

on my monitor now I'm on 0% brightness and during the day it's ok for me, but at night is much too bright, and I don't know at what specs to look at when buying a new monitor that will be able to get much lower brightness.

\n\n
\n\n

I switched from a sony vaio laptop with TN screen to a MVA monitor (Benq EW2430)\nand 0% brightness is ok for me during the day, but sometimes, evening/night I need it much lower brightness. I'm trying to pick a new monitor but I don't know how to choose one so that it would be able to provide a much lower brightness lower boundary.

\n\n

It will also be nice if I could control the monitor brightness from windows 10 right side bar (that you open when clicking button next to the clock), like with laptops, in my current one I can control the brightness only by touching the monitor physical buttons.

\n\n

please note: \nI can change the brightness in the video card settings but it's not the same as actually lowering monitor brightness, I would prefer to buy a new monitor

\n", "Title": "how to pick a lower brightness monitor", "Tags": "|monitors|displays|", "Answer": "

Display brightness should be in the specs as nits or candelas per square metre (symbol: cd/m2). Each model offered you should have a specifications page or document on the Internet you can reference, if not printed in the device manual. Look for the lower number in the range of nits from lower to higher.

\n\n

Alternatively, polarizing computer display filters are inexpensive and easy to add to nearly any display.

After trying multiple headsets, earphones, and any other shape of wireless audio device, with issues each time, I realized I have two choices:

\n\n
    \n
  1. To spend another $40,000 dollars in the hope of finding the one perfect headset.
  2. \n
  3. Get a decent recommendation from someone who already owns one.
  4. \n
\n\n

So here I am. My requirements are, I would have thought, simple. But surprisingly rare in practice:

\n\n
    \n
  1. Wireless. Duh. Should connect to a PC, so USB dongle or base station is okay.
  2. \n
  3. Has a microphone. On the headset, not the dongle/base station.
  4. \n
  5. Sounds better than a radio.
  6. \n
  7. Sounds better than a radio while using the microphone. Seems like a \"duh\", but this pretty much rules out all Bluetooth-based devices, except those using proprietary technology like FastStream.
  8. \n
  9. No white noise or buzzing when the audio output is silent. I don't constantly have sound playing, and I don't want to have to take my headset on and off depending on my sound usage at the moment. This tends to rule out many RF-based ones, which seem to have mild white noise when the audio is silent.
  10. \n
  11. No auto-off. This rules out pretty much all European ones, since EU regulations require broadcast stations to turn off after 5 minutes of silence. But like I said above, I don't listen non-stop, and I don't want to hack an inaudible sound just to prevent my headset from shutting off.
  12. \n
  13. Can listen while charging. I don't always remember to charge my headset, and the last thing I want is a forced 15 minute break from my computer, because the headset automatically turns off as soon as it's connected via USB (Why is this even a thing!?)
  14. \n
  15. Reasonably durable. Should last at least several months before breaking. Again, I too would have thought this was obvious, but cough Creative cough Logitech cough.
  16. \n
  17. Both ear pieces can produce audio at the same volume out of the box. I mean, I don't see how that would be a \"feature\", but my recently owned Creative Outlier Sports couldn't produce half the volume with the right ear piece as the left, so...
  18. \n
\n\n

I'm not particular about the shape, but if it's in-ear, I'd rather drivers that are less than 5mm, so they actually fit in the ear canal. If over-ear, I'd prefer material that doesn't gradually disintegrate, leaving pieces of itself everywhere.

\n\n

Unfortunately, most of the \"features\" I'm looking for don't appear in technical specs, and some of them are hard to find even in user reviews. I'm tired of gambling (and losing), so I'd really appreciate if someone can confirm owning a headset that satisfies all of the above.

\n", "Title": "Looking for a simple wireless headset with microphone", "Tags": "|wireless|audio|headphones|headset|microphones|", "Answer": "

I've been using the Logitech G933 for almost a year now, and it's been answering my requirements.

\n
    \n
  1. Wireless, with a USB dongle that's as small as many bluetooth dongles (Less than 2 inches).
  2. \n
  3. Detachable microphone on the headset, as well as a button to turn the microphone on and off. The microphone's connection to the headset seems like a standard 3.5mm, but I haven't tested replacing it. One flaw is that it has a "flexible" handle that seems to keep going back to the straight position, no matter how many times I try to bend it towards my mouth. It's hearing range is quite tight, so putting it near my mouth is a must to be heard clearly.
  4. \n
  5. Excellent sound quality, as far as my ears can tell. Can use it to play games, listen to music, watch videos, and not feel anything off.
  6. \n
  7. Same as 3. The microphone has no effect on the sound quality, and is actually at a semi-decent quality itself.
  8. \n
  9. Sound quality is crisp, even at a long distance. At worst, I had mild sound cut-offs while on a different floor from the dongle, but no noise.
  10. \n
  11. Unfortunately, it does have auto-off if silent for a while. But it doesn't lose sync with the dongle, and there's a physical on-off button on the headphone itself, so it takes only a second to turn it back on. It's better to be charging it rather than wearing it when not listening to anything, anyway.
  12. \n
  13. I've very rarely encountered running out of battery, but the USB-C charging port can be used while listening, with no issues, other than the cable getting in my face. The port is only for charging, so you can just as easily connect it to a computer or a wall socket USB charger. The charging port is on the left ear, which may or may not matter depending on whether the nearest USB port is on your left or right. Using a magnetic USB-C charging cable (bought separately) makes the process of setting the headphones for charging, and picking them up, extremely smooth and fast, as well.
  14. \n
  15. The pieces of plastic that hold the earphones extension mechanism are not durable enough to hold the weight of the earphones. Depending on how you hold the headphones they may break. However, since it's just a piece of plastic, they can be easily reinforced with duck-tape or rubber band, or anything else that's slightly more durable, and the problem is solved. The important thing is that the electronics are durable, and even with the plastic piece breaking, the headphones continue to work perfectly fine. Also, only that small plastic piece broke, while everything else, like band or ear cushioning, isn't showing even mild signs of wear. So, despite being a fragile Logitech product, it's been holding up reasonably well.
  16. \n
  17. Haven't noticed any issues with the volume balance.

I've never planned to upgrade my CPU. However, most of the components in my PC have been upgraded, and the CPU is now the performance bottleneck. It doesn't flinch except for gaming where it is maxed out, while the GPU still have quite a way to go before being maxed out.

I'm about to buy a server, for a Django system (Ubuntu + Django + nginx + postgresql) I have two options:\n\u00a0\nDual Intel Xeon 5420 16GB DDR2 240GB SSD\nor\nI7-2600 16GB DDR3 240GB SSD

\n\n

Which of these setups would you recommend?

\n", "Title": "Server: Dual Intel Xeon 5420 vs I7-2600", "Tags": "|processor|server|", "Answer": "

My main computer (at it now) is an i7-2600k. I built it myself, installed Windows 7 Ultimate, and have run it for years. It's getting old, but I still love it. Best home computer I've ever built or owned.

\n\n

However, I completely disagree with @Natsu. The i7-2600k is not a server CPU:\n\n

  • It does not support ECC nor Registered (Buffered) RAM, the Xeon does (winner).
  • \n
  • The Xeon uses DDR2 while the i7 uses DDR3 (winner), but both at 1333MHz.
  • \n
  • The i7 will forever be alone, the Xeon comes with a mate (winner).\n Why? Your anticipated server software stack (Ubuntu + Django + nginx +\n postgresql) will benefit greatly from the second CPU. Most software we run on\n home computers often doesn't need or can't use a second CPU effectively, but\n your server software should utilize as many cores you can throw at it.
  • \n
  • The i7 is top of the line, which means end of the road. You can upgrade the E5420 \n to dual X5450 @ 3.0GHz for less than $20 each (winner).
  • \n\n

    Now, this is assuming you are getting ECC RDIMM memory with the Xeon setup, and the motherboard supports the X5450 (it should, same CPU family). If not, then you aren't getting a true server, but rather a glorified home computer. I build and use both types of machines, \"home/small business\" desktops and full-on enterprise servers. The difference in memory is worth it if you want reliability. What is the difference? You know those random crashes, lockups, or errors that just don't make any sense? Unrecoverable memory errors are often the cause, and with Non-ECC Unbuffered RAM, they occur about once a month, while with ECC Buffered RAM, they happen about once a year. Power issues, heat, sunspots, proximity to nearest nuclear power plant, and many other factors affect these rates, but that's about average, 1/mo vs 1/yr.

    \n\n

    Make sure to get a server chassis, not some Rosewill or Corsair case, if up time is important to you. Multiple hot-swap fans, dual hot-swap power supplies, hot-swap drive bays, out-of-band management, all contribute to the qualities that make a server a server.

    \n\n

    I buy HP Proliant DL380 G6's: 4x 1Gbps NICs + iLO mgmt port, 6Gbps SAS RAID controller w/512MB cache, 2x 72GB 10k SAS drives, 2x450W hotswap power supplies, 2x E5504 Quad core 2.0GHz, 8GB DDR3 ECC RDIMM @ 1333, for $85.

    \n\n

    I can upgrade to 2x X5660 Hexa-core @ 2.8GHz for $50, and put in 8x 146GB 15k SAS drives in RAID10 (584GB yield) for $80 (refurbished). Memory prices constantly change, but right now 2x 8GB ECC RDIMMs is $25, so $300 will max out the machine w/24 sticks for 192GB RAM.

    \n\n

    Add misc. cords, some more RAM, rails, spare parts, tax, shipping, $300-$400 total for a great little server. Since I'm buying refurbished, I like to keep 25% replacement on-hand: I get 2 extra drives for every array of 8 (one server), and 1 extra power supply for every 2 servers (each having 2 PS in them). In over three years, I've had one drive die (RAID10, so I swapped it out, no problem), one motherboard die (when we moved to a new building, hmmmm...) and no power supply, CPU, NIC, or memory problems.

    \n\n

    I don't know where you are or what's available to you, but my advice is this:\nIf you need a server, buy a server. These 10 year old HP's do a great job on the cheap, and they are but one possibility.

    The TDP of an i5-8269U is 28 watt.

    \n\n

    TDP = thermal design power = most power cpu will draw when running @ 100% = one of the best ways to gauge a CPU's impact regarding power draw.

    \n\n

    https://ark.intel.com/content/www/us/en/ark/products/137980/intel-core-i5-8269u-processor-6m-cache-up-to-4-20-ghz.html

    \n

    if I use... for general purpose... is there a countable battery draining time?

    \n
    \n\n

    probably not.

    \n\n

    General purpose use will rarely get cpu usage high; would kind of have to define what you mean by \"general purpose use\".

    \n\n

    The i5-8269 is an 8th-generation Intel Core i5. You mention the #1 is the base 13' mac: 1.4GHz quad-core 8th-generation Intel Core i5 processor but do not specify the CPU model number. In any case if both CPU's are an 8-gen cpu then for general purpose use those CPU's are likely not run anywhere 100% thus they will typically down clock in frequency to save power. This is known as frequency scaling or cpu throttling.

    \n\n

    as I type this, the i7-6700k in my win10 desktop pc is a 4ghz cpu having TDP of 91 watt, but is currently only running at 0.8 ghz per CoreTemp, thus drawing very little power. Basically every late model cpu will operate this way, such that you shouldn't worry about power draw based on cpu for general purpose use. But if you game or crunch numbers then the cpu would draw extra power and reduce laptop battery life.

    \n\n

    If you have to choose between two cpu's, both being 8th-generation Intel Core i5, then choose the one having the highest base clock frequency. That will provide better performance whenever needed, which should be rarely because you said \"general purpose use\". Laptop cpu's are very good now at power management and it would be incorrect to assume or infer that a higher frequency cpu will always draw more power.

    I have three screens connected to my PC and I want to rotate one of them so that it's vertical. I'm not talking about rotating the image; I know I can do that in Display Preferences. I am talking about physically rotating the monitor itself.

    Check if any of your display has a Vesa Mount. The mount itself uses 4 screws in a 75 or 100 mm square so you can use the screen in any orientation. 3rd party stands are easily available online, ranging from no-names to big brands like Dell or Iiyama. There are stands, wall mounts and desk edge mounts available. Most don't allow free rotation of the screen - you would need to unmount the screen and replace it into another orientation.

    Be warned though, I've had issues with cheap mounts sagging (the last vertical angle hinge).

    Also, two people are recommended for assembly.

    \n\n

    Since you listed your monitors in comments, the Dell E2218HN does have a mount, Dell even lists it as compatible on their MSA14 Single Monitor Arm Stand. That one is mounted to the back edge of your desk. While expensive, this is just an example product and there are cheaper ones. There is also a stand but I am not 100% it will be high enough for you to mount a 22\" vertically on it - it should be. The Phillips PHL 223v5 has a mount as well.

    Do note that TN displays (both your Dell and Phillips) don't have good vertical angles, regardless of manufacturer boasts. I have a 22\" Iiyama which had pivot in factory stand, with supposed 160 degrees vertical and it still does not look good.

    You don't really need an upgrade in anything.

    \n\n

    The common mistake of beginners, that they think, having a bigger/larger/stronger computer is a requirement for doing things uncommon for ordinary computer users. It is not.

    \n\n

    I type this answer for you on a 2006 macbook running a 32-bit Linux. Although for development, I use mostly servers (these are strong) and laptops (these are roughly like yours).

    \n\n

    Not that is important, how strong is your computer, what is important, what do you develop on it.

    \n\n

    Furthermore, you have a strong laptop. It can't be really upgraded, because

    \n\n\n\n

    We can formalize your specification so:

    \n\n
      \n
    1. You have the laptop specified in your question
    2. \n
    3. You have \\$4k
    4. \n
    5. This is what you convert to the possible strongest laptop (for AI development).
    6. \n
    \n\n

    Then the answer is this: buy the costliest laptop from $4k and you will end up with two laptops. But you don't need this second laptop.

    \n\n

    Today, AI development means most likely by using the video card as a massively parallel CPU, thus this $4k laptop would likely need a strong GPU, if you would really need it.

    \n\n\n\n

    You need these. Use a part of the $4k to buy AI books in the university book store (or rent them from the internet). Most internet sources are still nowhere to the quality of the paper books in an university book store (library).

    The specification table says its battery is '3-cell, 51Wh'.\nThis makes me think charger with 51W output is enough.

    \n\n

    However, the output of provided AC adapter is 180W.\nDo I actually need such high power charger?\nOr, is it safe to use lighter one because the battery requires 51W only?

    \n", "Title": "Charger for MSI gaming laptop", "Tags": "|laptop|adapter|", "Answer": "

    The specification of your laptop battery is 51 Wh, which is a unit of energy. Overly simplified, the battery could provide a power of 51W for 1 hour. Or 102W for 30 minutes. Again, it is not quite that simple, but the examples here are not entirely wrong either, and should allow you to get an idea of what this unit means.
    \nThe specification of your charger is 180W, which is a unit of power. I.e. it is able to provide a sustained power of 180W.

    \n\n

    Consequently, the two specifications are not interchangeable. If you use a charger specified for less than 180W, your laptop might not recognise it at all, or it will run with reduced performance. Or in the absolute worst case, the charger blows up, which might even cause damage to your laptop. Powerful laptops these days are often designed in a way, that the battery alone can not provide enough power to run all components at maximum performance. Instead, they require the charger(s) to provide enough power. And the other way round: some laptops can even draw more peak power than the charger is designed for. In these cases, the battery is used to provide the delta, discharging it despite being connected to an outlet.

    \n\n

    To answer your question: depending on which charger you buy, it might not be safe to use one rated for less than 180W. In any case, using a lower powered charger will result in lower performance of the laptop, or the charger might not be recognised at all. I strongly advise against using a charger rated for lower power than 180W in your case.\nJudging by the main components of your laptop alone (GTX 1070, Intel CPU with 45W TDP), it definitely needs a charger that can provide 180W.

    I came across something called the One Netbook One Mix 3S Yoga, which seemed to be exactly what I was looking for. However, after reading the customer reviews, I realized that this laptop has a problem with overheating.

    \n\n

    This was the only the only pocket-sized laptop I could find the internet. Is there a different one I may have overlooked?

    GPD is THE brand for such toys.

    \n\n

    But your list of requirements I think isn't realistic (and in a way not even relevant.) Even normal big laptops don't usually match those specs so why would you look for them in a miny device and then expect it shouldn't even be overly hot... (And TBH, comparing to the RCA Voyager Pro which has 1 GB RAM why are you looking for 16 GB?....)

    This looks like a lovely little toy, but I am unclear which antenna to use with it , and those on the site cost more than double the price of the receiver itself. It collects ADS-B (aircraft info) which I intend to process in software.

    \n\n

    I am a pure software guy, with no knowledge of hardware, who is thinking of buying such a receiver to play around with it.

    \n\n

    I live two miles from a major airport. Any idea if I could get away without an antenna (told you I know nothing of hardware ;-)? If not, what's the cheapest I can get, with post & package to the UK? I would prefer to use it indoors, if at all possible, rather than running a cable out to the garden, or even hanging it out of an upstairs window.

    \n", "Title": "Cheap SMA antenna for this ADS-B (aircraft info) receiver", "Tags": "|antennas|", "Answer": "

    UK amateur radio stores will have SMA antennas and connectors, as SMA is the most common connector for handheld transceivers. Please specify you want a UHF antenna for monitoring 1090 MHz ADS-B/MLAT aircraft transmissions. Conventional aircraft voice radio is 108-136 MHz AM; make sure to specify to the seller you need 1090 MHz. Also, make sure to get a standard male connector as there are 'reversed male' SMA connectors.

    \n\n

    My Yaesu VX-5 HT receives aircraft UHF transmissions with its factory stock two metre rubber duckie antenna 20 miles LOS from PDX, but you can also obtain a connector and coax to attach it to an antenna in a window or an exterior omnidirectional antenna if that's not enough signal for you.

    \n\n

    A vertical antenna is preferred as aircraft radios use vertical polarization.

    \n\n

    How cheap is cheap? Here are rubber duckie 1GHZ capable SMA antennas which attach to the receiver, a broader selection of all that vendor's 1GHz capable antennas, another vendor's choices, and other selections. Put the receiver module near a windows on a pie plate or other flat metal object to provide a ground plane.

    \n\n

    1GHz UHF mag mount antennas can be ordered with the SMA connector to get it further away from the module if needed.

    \n\n

    If you need cheaper, get an SMA male to PL-259 female connector and a metre of stiff, solid copper bell wire at a hardware store, or out of your junk bin. Wrap the bare end of one piece of wire around the exterior of the PL-259 (larger end) connector and run that to a radiator or other ground. Take the rest of the wire, strip off a couple of cm on one end, fold the bare wire with pliers, and jam it into the interior of the PL-259; the other end goes straight up into the air.

    2) StarTech.com has a Thunderbolt 3 device with one USB-C 3.2 in, two 3.2 USB-C out. The second StarTech out port could be converted to HDM(I). Since your monitors also accept HDM(I), adding such a conversion cable provides the second signal to each monitor. Then, an app which runs in Win10, an iOS phone/tablet or Android phone/tablet tells your monitors to toggle (pro version) between the USB-C 3.2 A/V data input to the monitor and the HDMI A/V data input to the monitor.

    I am looking for a tablet, which I will use only for email and, possibly, browsing (reading news items only). No games, videos, music, etc.

    \n\n

    Bluettoth is not required; I am undecided about a SIM card.

    \n\n

    I would prefer Linux, but could live with Android out of the box, especially if I could install Linux over it.

    \n\n

    The device should be large enough to read, but should fit inside a jacket pocket, so maximum size about that of a Kindle Paperwhite.

    \n\n

    Battery life is of great importance to me, to the extent that I would prefer a back & white, or greyscale screen, if there were such a tablet.

    \n\n

    The cheaper, the better, but features mentioned above take precedence.

    \n\n

    End of question, only read further if you want an explanation.

    \n\n
    \n\n

    Background: my current 'phone suffered an accident, and I am replacing it. It is a Ulefone Power with a 13,000 mAH battery (yup, you read that correctly). I generally charge it every 5 or 6 days (side note, I can heartily recommend all UleFone models; this is my 5th or 6th over the years. Affordable, full featured, cheap, but realisable).

    \n\n

    As per my question How can I escape Google?, I don't want my soul tracked by Gogole, Facetweet, etc (I don't even use them - directly - but they are tracking me). So, I have decided to switch to a dumb 'phone.

    \n\n

    I recall only ten years ago getting months between charges on a small, greyscale, Nokia, so will look for something similar.

    \n\n

    I only really use a 'phone when job-hunting. Every 12 months or so, as I am freelance. A handful of people use WhatsApp, but I can retrain them to use SMS.

    \n\n

    Beyond that, I have become accustomed to having email on the go, rather than just reading & replying when I get home of an evening. I have also taken to reading news headlines in the browser. A device that will let me do those with a modicum of privacy (let me worry about that) and a long battery life would be welcome.

    Hello community. I just bought an HP laptop (HP 15 da1032) about a month ago, but i noticed that the laptop was heating with minimum amount of work load (i tried installing Eclipse),it goes around (39 C), and there is only ONE fan and ONE heat pipe for cooling the CPU (i7 8565u) and the GPU (NVIDIA MX-130), and the laptop back panel is Plastic. Now i want to know is there a better fan or heat pipe for my laptop? or is there any back panel that fit with my model? i searched online but i couldn't find something talk about replacement.

    \n\n

    here is a picture of my laptop inside:

    \n\n

    PS: There is some videos on YouTube trying to re-apply the Thermal Paste, i thought my laptop would not need this cause it's new.

    \n\n

    and, i heard that back panels that are Aluminum or Magnesium alloy will do a better job for cooling, will this really help with my laptop? i was wondered if it's available for my laptop model. Thanks

    No. You are left with what the manufacturer deemed an acceptable cooling solution. Also, there are no replacement parts made from different materials.

    \n\n

    Changing/reapplying high quality thermal paste can give better results, even if the device is new. Liquid metal compounds offer the lowest thermal resistance, but can cause damage to your machine, both in the short term (they are electrically conductive) and in the long term (they don't get along well e.g. with copper).

    \n\n

    But it seems like you might be seeing a problem where there is none. The only temperature you mentioned is 39\u00b0C, which is completely safe and normal for modern mobile CPUs. Under load, they usually run above 90\u00b0C.

    In the US, finding a new laptop under $265 USD (That is the equivalent to 250 euro) is tough, but I have found a couple that might interest you. US laptops might be different than what European laptops can offer in build though, so keep that in mind. The only issue is you're not going to find an M.2 expansion slot on a budget laptop. Even my Dell Inspiron Gaming Laptop doesn't have one.

    \n\n

    Lenovo IdeaPad This option has pretty much everything you want. It has 4GB RAM, 128GB SSD, Windows 10 and a nice AMD CPU that is extremely similar to your CPU. I don't see an M.2 slot.
    \nASUS VivoBook L203MA This is another nice option. 4GB of RAM, 64GB of eMMC Storage, Windows 10, and a decent CPU. The screen isn't Full HD, it is 720p (1366 x 768). This even has a USB-C port.
    \nHP Elitebook 8470p This is an AWESOME laptop if it was new. This is a refurbished laptop, but that means you will get a lot more bang for your buck. Speaking from experience, this is a stellar CPU and RAM config with 8GB of RAM. 500GB HDD (SATA) and you can remove this one and add a bigger 2.5\" SATA drive down the road, DVD/CD Drive, 720p screen and a backlight keyboard. This is one of the best ones you can find below $250 USD.

    Given your use case of 50+ users in an office with at most one gypsum wall, I believe a more powerful router with more processing power than the Broadcom BCM47189 and BCM43217 processors in your existing ASUS router would be desirable. Also, a new router should conform to the new WiFi 6 802.11ax standard, and be capable of security with WPA2, WPA3, and 802.1X WPA Enterprise with a RADIUS Server. The latter may not be desirable now, but if you find later on you need that, you're prepared.

    Every PC, MacBook, and MacBook Pro which was donated to us had its HDD or SSD replaced, wiped to milspec standard, and then reused in a different chassis to assure no user data ever fell into the hands of another user. The process is not daunting by any means.

    If not, would it be possible or sensible to use and external graphics box connected over Thunderbolt?

    \n", "Title": "VR with Quadro M2200", "Tags": "|laptop|graphics-cards|gaming|", "Answer": "

    Your Lenovo P51 Laptop may be able to run VR if you use an external GPU box (also called eGPU's) because you have a Thunderbolt 3 port, which is what that uses.

    \n\n

    Here are some GPU boxes: Razer Core X (In RGB and Non-RGB 'flavors') and Gigabyte GPU Box with a Nvidia RTX 2080ti, Nvidia RTX 2070, Nvidia GTX 1080, Nvidia GTX 1070, or AMD RX 580 GPU's

    \n\n

    If you wanted the Razer Core X, you would need to pair it with a minimum of a GTX 1060. I strongly recommend you getting a GTX 1660Ti over the GTX 1060 because new GTX 1060's are hard to find, and going to be expensive for an older piece of hardware. The GTX 1660TI is the best bang for the buck that would run VR.

    \n\n

    If you wanted the Gigabyte's GPU box, I would purchase one with an Nvidia GTX 1080, Nvidia GTX 1070 or an AMD RX 580.

    \n\n

    These are the GPUs that will work and I recommend, in order of most to least powerful:

    \n\n
      \n
    1. RTX 2060 Super
    2. \n
    3. GTX 1070ti
    4. \n
    5. RTX 2060
    6. \n
    7. GTX 1070
    8. \n
    9. GTX 1660Ti
    10. \n
    11. GTX 1660 Super
    12. \n
    13. GTX 1660
    14. \n
    15. GTX 1060
    16. \n
    \n\n

    I wouldn't buy anything above an RTX 2060 Super without buying a laptop, where at that point, I'd find a laptop with an RTX 2060 or higher in it because you're going to be saving money at that point (and maybe even some bottlenecking from happening).

    \n\n

    Here are some GPU links that I like (In order from least to most powerful):
    \nNvidia GTX 1060 (Minimum) $400
    \nNvidia GTX 1660Ti $300

    We need Wifi APs for a small business.

    However, there are various expectations what I can't foresee. The last what I want, that trivial things, what the hardware could easily do, are simply impossible because we have no root access to our own devices.

    \n\n

    In Germany, AVM!Fritz is a very popular AP solution (it is even common that home ISPs simply make their devices obligatory), however they are regularly racing to make their systems so un-configurable as possible; and this added them to my blacklist. I did the same by Cisco, on similar reason (they are also wanting regularly a lot of money for firmware updates, and their relative recent devices from 2013 had a weak signal strength).

    The Ball Grid Array used in the Core i5-8350U CPU of the Thinkpad T480 is factory-soldered, and I would not even try to remove it to upgrade the CPU for any one of three choices:

    \n\n

    1) Unsoldering and resoldering BGA CPUS is very difficult without factory-level tools

    \n\n

    2) The chipset, also permanently soldered onto the motherboard, limits your CPU choices.

    \n\n

    3) Laptops are very carefully designed to exhaust waste heat, and adding a hotter CPU likely shortens the lifetime of the other components. You're limited to 25W maximum TDP, 10W normal for safe operation.

    \n\n

    Alternatives:

    \n\n

    A) If you need more GPU, likely since the T480 relied on the Intel UHD Graphics 620 in the APU, an external GPU device can be added, connecting via the USB 3.1 Gen 2 Type-C / Intel Thunderbolt 3 (Power Delivery, DisplayPort, Data transfer) interface.

    \n\n

    B) You may also consider upgrading the PCIe (NVMe) drive, following instructions starting on page 69 of your hardware manual, if you are bound by drive performance. That would require finding the model of drive you now have before shopping for a faster drive, but Lenovo's tech specs for that device don't show that information.

    For the foreseeable future, in an entry-level personal computer, PCIe 4.0 is rather nice-to-have instead of a must-have. Or to put it differently: there are much better ways to spend excess budget than on this feature. more RAM, (larger) SSD, faster CPU, faster GPU, you name it.
    \nVery few devices benefit from the increased bandwidth in a way that would be noticeable to the end-user. WiFi is definitely not one of them, the bandwidth here is not even close to saturating PCIe 3.0 links.\nYou also would need a PCIe 4.0 capable motherboard to unlock this feature. So far, only X570 motherboards have PCIe 4.0 in the consumer space. And these are way to expensive to be justified in a budget PC.\nIn addition to that, a Ryzen 3400G does not even have PCIe 4.0. The Ryzen 3000 APUs are still based on the Zen1 architecture, hence only PCIe 3.0.

    It's just that: a bunch of benchmarks cobbled together into a single score. Only the devs know how well these benchmarks scale to multiple threads, and how they weigh the individual results to condense them into a final score. So maybe don't focus too much on this.

    \n\n

    Let's rather look at the CPUs themselves. A 3900X has a 50% higher core count compared to a 3800X. And it increases almost all CPU resources by at least 50%. Some shared resources like L3 cache even increase by 100%. If we stopped here, it would be safe to assume that the 3900X is 50% faster than the 3800X, at least in multi-threaded benchmarks with ideal scaling.\nWith 2 notable exceptions:
    \n1) Thermal design power is the same. This causes the 3900X to run at lower clock speeds when all cores are loaded heavily. Dropping the performance increase to a bit less than 50%, at least if the user does not overclock.
    \n2) Memory bandwidth. While the 3900X has almost double the write memory bandwidth compared to the 3800X (due to 2 chiplets vs. 1 and limited bandwidth from chiplets to the IO-die), the read memory bandwidth is practically the same. This causes less than 50% performance advantage in benchmarks (and applications) that become memory bandwidth limited at higher thread counts.

    \n\n

    In conclusion: The 3900X can be nearly 50% faster than the 3800X in multi-threaded benchmarks and applications. But as always, it depends on the application.

    Which is better for scientific and engineering computation/simulations, the Intel i9-10900X or the AMD R9-3950X?

    There are indeed fields of computing where Intel's X299 lineup still performs better than AMD's Ryzen 3000 series. And even offers better performance per dollar. Engineering/scientific simulations like CFD and FEA is one of these areas. Source: I have been working in this field for many years now.

    \n\n

    You already mentioned the key specification here: memory bandwidth. AMDs Ryzen CPUs stop scaling at around 6-8 cores due to a lack of memory bandwidth when running parallel CFD codes. See for example the results here: https://www.cfd-online.com/Forums/hardware/198378-openfoam-benchmarks-various-hardware-14.html#post763993

    \n\n

    Intel CPUs can draw a lot more power than their rated TDP for short periods of time. That's how turbo boost works. So can AMD CPUs. Unless you are overclocking heavily, you won't see 300W sustained power draw from an I9-10900X. Not even close https://www.anandtech.com/show/15039/the-intel-core-i9-10980xe-review/2

    \n\n

    Less than 50W idle power consumption for a whole system on an HEDT platform might be a bit optimistic. You will probably end up in the 70W range with a typical configuration. But this figure does not depend on the CPU alone. Motherboard, drives, GPU... all play a role here.

    \n\n

    Why doesn't AMD release a Threadripper CPU with less than 24 cores, at a more reasonable price?

    \n\n

    I can only speculate, and there will be a lot more reasons than I can come up with in a short paragraph. But one of the most important ones will be this: AMD is a relatively small company compared to Intel. So far, their goal is not to cover every niche possible with the perfect product. That was Intels goal. And let's face it: scientific and engineering computations on moderately priced workstation PCs is a niche application.

    \n\n

    More L3 cache is nice to have, but outside of edge-cases, it can not completely make up for a lack of memory bandwidth.

    \n\n

    Btw: if you are looking for a cheaper TR3000 alternative that better fits your requirements, AMD still has something in their lineup: Epyc 7302P. The CPU and the boards are not exactly cheap, but still much better value and higher total performance compared to the cheapest possible TR3000 build.

    \n\n

    Edit\nforgot to mention this: especially with your applications in mind, I would highly recommend faster memory than DDR4-2933 or DDR4-3200 for both AMD Ryzen 3000 and Intel Cascade Lake-X CPUs. DDR4-3600 is around the sweetspot for price/performance.

    The Workstation

    The cheap route is to use a USB-C Hub. I have used this one across many devices and can vouch for it.

    \n\n

    The fancy way, you can get a USB-C Dock that is basically the same thing but is meant to be stationary, so has its own power supply and more functionality.

    \n\n

    Both of the above options would turn your desk into a generic \"Work Station\" at which you could sit down with any USB-C device and connect to all your peripherals.

    \n\n

    KVM

    \n\n

    If you want to have both computers at the same desk always on and easily swap back and forth, you are looking for a KVM (Keyboard Video Mouse). Unfortunately, USB-C is relatively new and I do not know of any that run directly from USB-C yet available.

    \n\n

    There are may kinds of KVMs available. Some split video cables, some split USB connections, and others that split both separately. You could convert from USB-C to USB-A and then go to one of these.

    \n\n

    What to look for

    \n\n

    USB-C is the connection and is part of Thunderbolt 3 but the two are not the same.

    \n\n

    You can charge many devices through the same port you connect to the hub. The first device I listed has this functionality, known as power pass-through. Often sold with the Power Delivery (PD) mark followed by the power rating for that device.

    \n\n

    If you are going to use one computer on each monitor and want to share a mouse and keyboard, you can use software like Synergy. It's a great software that I have used many times.

    Note

    \n\n

    There are several very similar questions on this site and no perfect answers. It's a messy area to search for, but once you know what your looking for you can find the solution that works best for you.

    \n\n

    Edit: Answer to comment

    \n\n

    For keyboard and mouse, there will be absolutely no problem going to USB-A. The only problem is that you said your computer only has USB-C outputs and no video output. I would recommend going from laptop to this cheaper hub and then from this hub's HDMI and USB-A to the above linked KVM. Use the first Hub I linked in the exact same way if you also want power pass-through.

    My question is whether adding the new graphics card will prove too much for the 300W power supply. The estimate I have made was 88W for the CPU, based on the so-called Thermal Design Power or the amount of heat the sink needs to dissipate. I also know that the new card will require about 120-180W of power, depending on the model. This leaves us with about 100 Watts for everything else in the machine.

    \n\n

    Basically, the question is whether I should be able to make this work without swapping the power supply. I really like the latter and am not sure whether the company still makes something similar.

    \n\n

    How can I estimate the power consumption of the rest of PC?

    \n", "Title": "Adding Video Card to PC: Power and Wattage Considerations", "Tags": "|graphics-cards|pc|power-supply|power|", "Answer": "

    We can do the math to calculate the power consumed by CPU cooler, motherboard, RAM, and HDDs for each rail (bus, or voltage specific circuit) of the power supply ('PSU'), relying on the specs of each component. Go back to each manufacturer's website to find their spec sheets; don't rely on the reseller's data, and use the startup current as that's the maximum amperage .

    \n\n

    Available power from your 300W PSU per page 4 of the manual:

    \n\n
    \nVotage * Amperage * Tolerance factor = Max Watts\n  Rail  Amp Tlrnc   Watts\n  +12V  22  0.96    253W  \n  -12V  0.5 0.89    5.3W  \n  +5V   20  0.94    94W * Max combined 103W  \n  +3.3V 21  0.94    65W * Max combined 103W  \n  SB    2.5 0.94    11.7 standby +5VDC\n\nThe Tolerance factor allows for variations in the load and line regulation.\n
    \n\n

    For example:

    \n\n

    Drive 1, the Seagate ST1000LM014 uses 1 Amp at 5VDC at startup, or 5W on the +5V rail
    \nDrive 2, the Seagate ST4000LM024 uses 1.2 Amps at 5VDC at startup, or 7W on the +5V rail.
    \nBut, the Asrock Z97E-ITXac motherboard has no power consumption data, so you'd need to contact Asrock support to find what its maximum power draw would be, separate from the CPU, RAM, and other components.

    \n\n

    Adding 120-180W of additional power draw to a system with a 300W power supply is risky, and I would not do it without an accurate verification of what the current power consumption is.

    My conclusion: Upgrading the power supply would be wise.

    Asus Zenbook Duo - Core i7-10510U, 16 GB RAM (DDR3), 1 TB SSD, 2 GB GeForce MX250

    \n\n

    Asus TUF Gaming A15 - AMD Ryzen 7 4800H, 16 GB RAM, 1 TB HDD, 256 GB SSD, 6 GB GeForce 1660Ti

    \n\n

    [There's some uncertainity in models of A15]

    \n\n

    I'm just a student but I like programming so I do use Android Studio, Visual Studio Code, PyCharm, and some other IDEs which require less resources than how much Android Studio does.

    \n\n

    Sometimes I need to create my own assets for my application, so I use PhotoShop.

    \n\n

    I do make some videos for YouTube and I wish to use Adobe After Effects which I have actually used once on my desktop and as you will expect it ofcourse took my an hour to render a short video.

    \n\n

    Each of the above laptop have some attributes that I like but are confusing me.\nMy first preference is the Predator Helios 300 for sure, except it's battery but this is acceptable because it's just powerful.

    \n\n

    Actual confusion arises due to Asus A15 which is launched recently (yet to be launched in India) because the processor as per I've heard is faster than the i7. But again, some people said me that I should go for Intel because it's reliable. I don't know if AMD lasts less than Intel. Should be a Myth just like when people compare Snapdragon and Mediatek. [Asus TUF Gaming F15 has Intel Intel\u00ae Core\u2122 i7 10750H but looks like this one will take a long time to arrive especially in India]

    \n\n

    Also A15 has a plastic build with 3 heat sinks while Predator is all metal with 4 heat sinks.

    \n\n

    Coming to the last one, I definitely wanted the Zenbook Duo for its second screen which indeed is very useful. But, it has DDR3 RAM, weaker graphics, and only 2GB of video RAM. It does have a 10th Generation i7, but it is labelled U, meaning it is low powered.

    \n\n

    As I have mentioned earlier I need to use After Effects so I can drop idea of getting the Zenbook Duo.

    \n\n

    [Zenbook PRO Duo is way too much expensive than these 3 so that's not an option for me]

    \n\n

    TUF Gaming A15 is available with 90Wh battery which could be helpful.\nThere isn't much difference else. But plastic body, can it be less rigid than Predator? That's why I'm confused else Predator is a good choice.

    \n\n

    The aggressive gaming style of laptop won't be a problem; the Predator looks nothing less than a beast. I would be mostly home and wrapped around that charger, but even if I'm out, the Predator gives at least 2-3 hours of battery life [on light tasks, anyways won't be gaming outside of course] so shouldn't be an issue.

    \n\n

    Which one should I go for? All these laptops are in price range of around 1300-1500 USD [1 - 1.20 lakh INR].

    \n\n

    Also I hope it won't affect the performance if the laptop was released 1 year. The Predator, was launched in April 2019.

    \n", "Title": "Which of the mentioned laptops should be better for my needs?", "Tags": "|laptop|graphics-cards|processor|memory|intel|", "Answer": "

    Since the Acer Zenbook Duo only has DDR3 RAM, and the inferior MX250 GPU, I'd rule that out.

    \n\n

    Your PH315-52-76WX model of the Acer Predator Helios 300 looks like a good buy, but the Model B07S8D3C8J TUF Gaming A15 with 256 GB M.2 NVMe SSD, Ryzen 7, and 1660Ti GPU has a faster internal drive and WiFi 6, whereas the Predator only has WiFi 5. Of course, if you will use Ethernet instead of WiFi on large file transfers, that's irrelevant.

    \n\n

    The plastic chassis of the TUF may be less of a drawback since it has been tested to meet MIL-STD-810H standards, and its 90 Watt-Hour (8+ hrs of web browsing) battery plus the 144Hz display at 1920x1080 is attractive.

    What PC (laptop or desktop) would be good for a relatively newbie coder who'll be entering a UX/UI boot camp soon?

    \n\n

    A little background: I'm a lifelong PC/windows users (I'm coming from the business world), and while I've purchased and tried a few Apple/Mac products in my life, they've never quite gelled with me. I tend to dislike the fact that they're SO proprietary, i.e., I resent spending money on special chargers and cables, and I dislike the garbage bin (sorry, I'm nitpicking).

    My PC only has USB-A ports. I want a hub which I can connect (so it needs USB-A connection) and which provides both USB-A and USB-C ports. I do not need any of the fancy optional features USB-C can provide like Thunderbolt, DisplayPort or high power output, just plain USB 3 will do.

    Therefore, I'd suggest adding a USB-C card such as a $19 card from NewEgg, or a $25 card from Amazon. Both connect to PCIe slots on your desktop motherboard, so please check that you have the necessary card slot available.

    I want a new PC, mainly for work, plus other minor stuff like browsing, Netflix, and Skype. I work in economics research, therefore I need to easily work with reasonably big datasets (say, ~25Gb of data) and pure, brute computational power for simulations, model estimation, some light machine learning task. I write code mainly in R/Python/Julia/Matlab/Stata languages, plus LaTeX for writing presentations and articles. I can get some discount on Dell machines through my Uni, which restricts the options to basically two alternatives:

    \n\n\n\n

    Both machines fit the portability requirement, as I can also work at a conference without carrying around a stone slate. The after discount prices are close enough (<1500\u20ac).

    \n\n

    Here comes my question then: which one should I favour, knowing my work needs? As of now, ports and expansible RAM on the Latitude are an advantage that comes at the cost of separated AC port and thickness, while the XPS has fewer ports, RAM is soldered but has more portability and is powered via USB C (one less charger to carry around)?

    The XPS with a i7-10710U has more processing cores than the i7-8665U which could help it tackle multiple simultaneous programs or threads. Performance improvement in programs, which are not memory-bound will be lower. It could take advantage of faster memory access, but Dell chose slower memory for the XPS. Ouch!

    \n\n

    The Latitude with a Core i7-8665U advantage can run at a higher operating frequency than the i7-10710U, and its memory is faster (2400 MHz vs 2133 MHz).

    \n\n

    Since the memory is faster and more expandable, Windows 10 Pro is included (so it can join domains), and the warranty is three years instead of one, I favor the Latitude.

    A more detailed comparison chart is available for review. It shows the Latitude has a USB 3.1 Gen 1 without PowerShare, a USB 3.1 Gen 1 with PowerShare (allows the battery on your laptop to charge a USB device), and a Thunderbolt\u2122 3 w/ DisplayPort & Power Delivery. PowerDelivery, in theory, allows charging in and charging out, but I would confirm that with Dell Latitude Sales as to power in capabilities over the Thunderbolt port; they're making bucks off the sale, they should help.

    First of all, VGA is analog and the rest are digital. This limits somewhat your options because, in case of NVIDIA graphics cards, the 900 series was the last one to support analog video through DVI-I. According to this reply, there are some old AMD cards that also support it and you also might be able to convert between Display Port and VGA.

    Since very few cellphones nowadays have external antennas, and they are not Android but are 2G only, a cellular repeater or femtocell at 20m elevation is recommended.

    \n\n

    \"Layout

    \n\n

    It must match the cellular voice and data frequency bands used by your provider, wherever you are, and may require regional regulatory approval. They will work, as adding another cellphone (Android or otherwise) may or may not work, especially since the sensitivity and rejection figures needed to determine if that second phone would work well are rarely published. A repeater also eliminates the need for another cellphone and another SIM card.

    \n\n

    An active repeater adds signal gain, whereas a passive repeater doesn't. Therefore, an active repeater is preferred.

    \n\n

    The following picture shows two antennas coupled together; if there's an active repeater between the antennas instead of just cable, that would be ideal and much more likely to work with no problems, rather than an unamplified passive approach.

    \n\n

    If there is no femtocell or cellular repeater approved, let's talk about external antennas coupled through low-loss cable to form a passive repeater. \n\"passive L50 ohm LMR400 cable would be my choice for cable; see https://info.wilsonpro.com/ty-installationguide/ and https://www.wilsonamplifiers.com/blog/understanding-coaxial-cables-the-complete-guide for more.

    \n\n

    There are apps for your phone which can provide the location of the cell towers you connect to at that 20 meter height. A Yagi-Uda or other directional antenna can be pointed at that cell tower, and a cable dropped from that position to your cellphone. However, that depends on knowing what frequency bands your cellphone carrier uses, as directional antennas are very frequency-specific.

    Both of those suggestions let you continue to use your existing iPhone, and its Bluetooth connectivity, without buying another SIM card and paying for another cellular device every month.

    \n\n

    I've had some luck with cleaning the optical sensor using an alcohol pad, but that doesn't always work.

    \n\n

    I'm sick of this problem. I want a shredder that:

    \n\n
      \n
    1. Is not dependent on an optical sensor. It's okay for it to have one, as long as there's a manual override, so the shredder doesn't go to the trash if the sensor is broken.
    2. \n
    3. Is high-security. None of those long paper strips that can be reassembled into a document. I believe that level 4 is reasonable.
    4. \n
    5. Supports a 220 volt power connection.
    6. \n
    7. Is not too expensive hopefully.
    8. \n
    \n\n

    Does anyone know of a shredder that meets these criteria?

    I loved the E6510 (15.6'') / E6410 (14.1''). They're robust, a dream for maintenance, and are easy to clean. Both support 8GB DDR3 (confirmed), maybe 16GB.

    \n

    Previous E6500 (15.4'') / E6400 (14.1'') series are similar for maintenance.\nThose Core 2 Duo are still performing very well with Vista with only 4GB DDR2 (or even 2GB !), if coming with a dedicated graphic chip (Nvidia NVS 160M) and a professional grade SSD. (Word or Excel opening in less than 1 second on Windows Vista.)\nThey are probably a little aging for Windows 10. I haven't attepmpted this.\nE6500 / E6400 had the issue of peeling speakers paint.

    \n

    More recent series, with the E6520/E6420 and E6530/E6430 design, are also very good, although maintenance is a little less easy, as having more than one screw on the bottom to open them. The E6530/E6430 brought USB 3.0, altough E6510/E6410 series allows adding a USB 3.0 socket though the use of an ExpressCard and have an eSATA socket as well.

    \n

    Later series (e.g. E6540) are less reparable, at least for the display panel assembly which is monolithic. (The LCD panel is sealed.)

    If the notebook stays at work or home most of the time, I would go with a 15''.

    In your case, I would pick the E6510 (easier to clean) or the E6530 (more recent).\nNewbies focus too much on the RAM amount. I would'nt.\nA dedicated graphic chip (NVIDIA), the processor and an SSD instead of an HDD are way more important.\nFor instance, I have some old E6500 with Core 2 Duo, NVIDIA 160M graphics and 4 GB RAM that still beat more recent E6520 with i5 but standard Intel GMA graphics. Both have a good SSD.\nThe question is always where the bottleneck is. It is useless to have tons of RAM if the processor cannot follow or if the HDD is slow. Nowadays it is rare going out of RAM with standard desktop use. 4GB often suffice and 6GB is comfortable.

    I would like to connect one USB Headset to two separate computers, hearing the audio of both at the same time. USB Switches exist, however they only allow one computer to control the headset at a time. It most certainly needs to be a special device that knows how to handle sound data and mixes it from two different sources. Does something like this already exist? If possible, buying one is the preferred option however I may also invest some time and tinker it with a raspberry pi if some tutorial for this exists.

    \n", "Title": "Connect one USB headset to two devices, playing both sounds simultaneously", "Tags": "|usb|audio|sound-system|", "Answer": "

    You want a "Sound Mixer". If you are working with analog audio signals, there are several options: Here is a cheap one that has 4 inputs and here is a battery powered option with better quality that has 2 inputs.

    \n

    Unfortunately there are not any devices that share a USB connection between multiple hosts. That is just a limitation of USB. USB was designed as a master-slave system for peripherals, as such, it has a strict "Tree Network" topology. This means, no matter how you slice it, multiple hosts (computers) can't share a USB device. Similar issue on this recent question.

    \n
    \n

    Because it is common to want this functionality, there exits several software solutions. I know this is outside the context of both this site and what you want, but its really the only option. This is where the Raspberry Pi you mentioned may come in.

    \n

    You can find many options by searching for a way of sharing either the USB device, or the sound source over a network. A good example of this is the program Synergy. The original version of the program (there is a second more complicated version now) shares your mouse and keyboard between multiple computers by connecting your peripherals to one computer that acts as a server and sends its kb/m inputs over to another computer through a network. The program running on the second computer decodes this information and presents it to the operating system as a kb/m. The second computer can't access the keyboard or mouse directly, it only gets the keystrokes that are sent to it.

    \n

    To do this with Audio there are programs like PulseAudio and Virtual Audio Cable. I can't say I have experience with either program so you may want to do your own research on them. You could use a Raspberry Pi to act as the host that you plug your headphones into, but you will probably not see any benefit over letting one of your computers be the host unless neither of those computers will always be available.

    I'd recommend looking at models from the X220 onward. The X220 though, is a firm favourite in the community for a number of reasons. It was the last X series Thinkpad to come with the old style (and almost universally said to be) superior keyboard. It was the first generation to have Sandy Bridge processors, which saw a sizeable jump in performance. And as it's one of the most popular models amongst enthusiasts, resources for modding, upgrading, fixing, and repairing them, be it in hardware or software, are plentiful.

    \n

    Just bare in min that if you were to get an X220, you'd need the i7 CPU version in order to get USB 3.0.

    \n

    The X220 is a favourite of Thinkpad fans but my recommendation would still hold true for later models such as the X230, X240 etc... There is one more thing to keep in mind though. Thinkpads are/were business laptops. They were sold by the thousands to big business. They were known for being durable and perhaps as a result of that reputation, a lot of them saw a tough life. So it's all too common to finnd ones for sale that are in poor condition. When buying a Thinkpad, pay close attention to the screen's hinges, the bezel around the screen, and the corners of the main body. If you wanted, you can always ask for further advice on the condition or price of a Thinkpad that's for sale, one one of the Thinkpad community's forums.

    I'll second the recommendation for the Thinkpads\u2014you might even be able to grab a T or X series within your budget depending on launch offers\u2014but since you mentioned Linux, I thought it would be remiss not to mention there are a couple of 4800H laptops with options for Linux preinstalled, no OS or even no storage, including the Schenker VIA Pro, the Tuxedo Pulse 15 and the new Slimbook, KDE or otherwise, all roughly at that \u00a3/$/\u20ac1000 price point. Some of them plan to offer 4K OLED displays as upgrades, but that would probably take things outside your price range. They're also a good deal cheaper if you can import from a Chinese reseller, say through a friend travelling through or living there.

    \n

    As I understand it from a couple of reddit threads (1) (2), the chassis is from the same ODM, TongFeng. Some benchmarks are available here and a comprehensive english review on youtube. The battery life seems to be quite good thanks to the large 91 Wh battery, and you should see well over 5 hours of battery life, closer to 8 to 12 hours. Gaming laptops with the new Ryzen and a larger ~90 Wh battery option should honestly achieve similar run times under light to idle loads, and even a smaller batter should meet your 5-hour target, though obviously if you wanted to use the GPU heavily for video editing or something that would take a toll.

    \n

    The performance may different significantly due to cooling, so looking at the specific models you plan on buying would be better, but there are quite a few comparison benchmarks of the Ryzen APUs from, e.g. Notebookcheck. Notably, the 4800U seems to trade blows in single core performance especially, though the increased power limits shows in multi-core workloads. They are likely essentially the same chip with different binning and enabled cores. The Vega 7 iGP is honestly comparable with the MX250 performance-wise, and I doubt you will have any problems with lighter games like Minecraft. Heavier games may require lowered settings, resolution or both to run at 60 FPS.

    \n

    The display covers 100% sRGB, which is not bad, though at the price range of a euro reseller you can probably get the better panels on, e.g. the TUF A15 which would have similar gamuts and a high refresh rate. Unfortunately, it does not have a second M.2 slot or a 2.5" drive bay, which limits expandability, and the keyboard backlight is poor. Overall, I would recommend it over laptops from larger OEMs if the combination of the H-series CPU and 1.5 kg weight interests you, if you want the convenience of the SSD-less configuration option or preinstalled Linux, or if you can get it from China yourself for a lower price. Otherwise, the Thinkpad will likely a good deal cheaper, and at your full budget you might be looking at laptops with the RTX 2060 instead. If you do end up going with a laptop from a more well known company, consider mentioning it to their sales that you don't need a Windows or a drive included. It's possible that they'll be willing to bump up some other hardware, include free accessories or even give you a discount, and the worst that could happen is they'll say no.

    I'm looking to get a server that I can run Ubuntu on, with the primary purpose of running the SPARK Pro toolset. I want lots of cores (\u226512) and lots of RAM (\u226524 GB), but I don't need much disk space, basically just whatever's required to install bare Ubuntu, the SPARK Pro toolchain, and the source code I want to do my proof/implementation work on. I definitely don't need a monitor, as I'm planning on SSH'ing into the server using VS Code. When I put in my requirements for NewEgg (I also want it to be relatively inexpensive: I limited it to $750), I got nothing but blade servers.

    \n

    Focusing primarily on this HP Proliant DL360P (though I'm not committed to that particular option), I was wondering if it'd be possible to put this into some other form factor other than a rack. E.g., for not too much more money to get a box I could house it in.

    \n

    Note (in response to @Wasabi in a now deleted post at the Engineering Stack Exchange): I don't know if I need a case, but I'm assuming I'd want something to reduce dust getting into places it shouldn't. I could be wrong. If someone knowledgable tells me I don't, using the "bare metal casing" counts as "some other form factor" for the purposes of my question. "Have you considered this really small, cheap rack?" also counts. I'm just looking for a reasonable solution to having a machine that suits my needs located in my home office, so frame challenges are welcome.

    Edit to add: I'm also willing to do some custom modifications to hardware (e.g., add RAM) after the fact.

    \n
    \n

    your < $750 and lots of cores is contradictory, but...

    \n

    The basic desktop/workstation (traditionally with a monitor) are no more than dual socket- meaning only 2 cpu's. They don't offer that much real estate, not like a rack server and you won't have many DIMM slots but they typically do 128GB of RAM no problem.

    \n

    Not blade server but rack server is what generally offers the most real estate and would allow for up to 4 cpu sockets. And would have the most DIMM slots available providing for 768GB to 1.5TB of RAM. $750 would only buy you a few DIMMS here. But a rack server is not required to be put in a rack, you can lay them on a desk, they will take up some space obviously, or you can lay them on their side on the floor against the desk. Expect to pay over $10,000 for a 4 socket rack server having whatever N-core cpu's and however much RAM. Try Dell's online build your own for something like 4-socket PowerEdge R840 to get an idea.

    \n

    https://www.dell.com/en-us/work/shop/cty/pdp/spd/poweredge-r840/pe_r840_12850_vi_vp

    \n

    Also check out supermicro. For what it sounds like you are wanting, look for a used/refurb rack server.

    \n

    You can sometimes buy all rack server components and build your own, but expect to pay over $750 just for the main board that is rack server style. Then add in power supply, cpu, ram, fans, and so on.

    \n

    a blade from a blade server can be tricky depending on what it's from, it implies its a blade of a larger system so don't assume a blade removed from that kind of system can operate on it's own like a standalone computer. So in this context no don't expect to use a blade without the rest of the blade server. If you have the entire blade server, then that implies you then have multiple blades... installed into some chassis. This chassis whether that's installed in a rack isn't a requirement.

It make sense?

    \n", "Title": "USB Power Meter to measure Smartphone Energy Consumption", "Tags": "|smartphones|measurement-devices|", "Answer": "

    You cannot measure the phones power consumption this way. The USB dongle will only see the current being used to charge the battery of the phone not the power the phone is drawing from the battery.

    \n
      \n
    1. You could use an application on the phone that monitors the phone battery and logs its usage. No external device can monitor the power the phone is using. This will be a fairly inaccurate measurement just because phones can generally only reference the battery voltage to determine its charge status.

      \n
    2. \n
    3. If you are willing to risk a phone the way to do this would be to open the back of the case, get to the battery connector, de-solder the phone's positive terminal and connect a current meter in line of this rail like shown below,

    I'm finally catching up w/ the 21st century and bought my first pair of truly wireless earbuds: the Sony WF-1000XM3.

    \n

    My issue is that audio quality degrades significantly when I connect them to my computer and enable the microphone. To do this, I have to switch from High Fidelity Playback (A2DP Sink) to Headset Unit (HSP/HFP), which forces the output to go from Stereo to Mono.

    \n

    For ~$200+, I was hoping to have better audio quality than my cheap wired earbuds+mic. I already bought 2 other earbuds at different price points and noticed similar or worse issues. Tried with Airpods Pro as well, but since I'm not on a Mac, I could never get the mic working.

    \n

    In short, I'm wondering if things change significantly with something like the Sennheiser Momentum 2 (or higher price point), or if I should consider non-truly wireless earphones, if I want quality audio and mic?

    \n", "Title": "Are there any truly wireless earbuds that support A2DP while using the microphone?", "Tags": "|wireless|bluetooth|headphones|microphones|audio-quality|", "Answer": "

    The A2DP or HSP choice is afaik a limitation of the bluetooth standard itself. You'll need to wait for an update of the standard for that to be fixed, but I'm not aware of such an update being in the works. Perhaps some company will come with a proprietary mode that improves this. The Plantronics/Poly headsets with the BT600 dongle do that to an extent, with that dongle they can run in HSP mode with stereo sound, but the sound is still limited to a 16 KHz sampling rate instead of the 44.1 for hifi sound, so that is clearly audible. If that is good enough, there is the Poly Voyager 6200 UC if you can live with a neckband.

    \n

    As you figured out, you will want to look for a wireless gaming headset. The connection is often described as 2.4GHz, lag free, or uncompressed. It appears that wireless gaming earbuds (truly wireless or with ears connected) with such a connection do not exist. Keep watch of this SoundGuys page, especially the Notable Mentions section, if you want to find out if the situation changes. They update their "best of" pages when new headsets come out. Currently it says the Epos GTW 270 Hybrid is the only pair of true wireless gaming earbuds on the market today, and importantly its microphone doesn't function when connected to the 2.4GHz dongle.

    \n

    edit\nI realized there is a bluetooth technology that supports this. It's called the faststream codec, though it is not really a new codec, just a different configuration of the standard SBC codec. Unfortunately it is very hard to find faststream supporting headsets. Google found the Creative Outlier Sports, though it is not true wireless. You'll also need a bluetooth audio dongle that supports faststream, because current desktops and phones don't.

    My old Texas TI-83 is dying on me after some 20 years of extensive use. It served me well, but it's quite crude when it comes to programming-related arithmetic. Specifically binary/dec/hex conversions, as well as bit-wise arithmetic. For such, I've relied on custom programs made by myself, that tend to get cumbersome interfaces to the point where I don't use them, but fire up calc.exe on the computer instead.

    \n

    So I'm looking for a similar graphing calculator similar to the Texas TI-xx product family, but one more suitable for programmers, if such a beast exists. That is, easily accessible ways to use the various features of the old calc.exe in Windows, when set to "programmer mode".

    Given that you're already familiar with the TI-83, I suggest considering the TI-89 Titanium. In language and UI design it's a descendant, but it is \u201cmodernized\u201d in a lot of ways and has many additional features.

    \n
    \n

    Easy way to convert between hex, dec and bin bases, with a few button presses rather by than executing a custom program.

    \n
    \n

    You can enter numbers like 0hAA and 0b1011, and print them with the \u25b8Hex, \u25b8Bin, and \u25b8Dec operators, or set the default output format to any of the three bases.

    \n
    \n

    Support for integers with different word sizes: byte, word, double word etc (8, 16, 32 bit).

    \n
    \n

    Only 32-bit is available; you'd have to do bit masking yourself to simulate smaller sizes.

    \n
    \n

    Support for bit shift, OR, AND, NOT and similar binary arithmetic.

    \n
    \n

    shift(value, count) provides a 32-bit sign-extending shift. or, and, and not act bitwise on integers.

    \n
    \n

    The ability to type out the whole calculation/equation on the display as done on Texas calculators. Not "one operand at a time" as in more classic/simplistic calculators.

    \n
    \n

    Yep, it's a TI! Also, if I remember correctly, the TI-83 text entry defaults to overwrite mode \u2014\u00a0the TI-89 defaults to insert mode like modern text editors.

    \n
    \n

    Trigonometry supported and easily accessible (like on the Texas ones). Radians + degrees.

    \n
    \n

    Yes. Trig functions are on the main keyboard, radians and degrees are available as a mode setting, and you can also enter and read vectors in polar or rectangular form.

    \n
    \n

    Must support engineering notation.

    \n
    \n

    Yes. The TI-89 has a dedicated key for entering the exponent "E" (which is a distinct character from text/variable-name "E". There is also an "engineering" output option to always use exponents that are multiples of 3.

    \n
    \n

    Some manner of graphic display (LCD, TFT etc). Resolution doesn't matter.

    \n
    \n

    160 \u00d7 100 LCD, no backlight. You can plot functions and also draw arbitrary graphics from programs. The normal input/output view fits 5\u00bd lines of text (at minimum height; divisions and matrices and such are taller), and you can scroll up easily to review and recall previous results.

    \n
    \n

    Actual buttons. (If I liked typing on touch screens, I'd use the app on my phone instead.)

    \n
    \n

    Check!

    \n

    Features/differences you didn't ask for but are noteworthy compared to the TI-83:

    \n\n

    Tip: First thing to do is to go into the settings and turn off "Apps Desktop", so you always start at the "Home" regular calculator input mode.

    The TI-89 Titanium is still in current production and can also be found cheaply on the used market (presumably from ex-students).

    \n

    I hear that the TI-92 / Voyage 200 has the same operating system but adds a QWERTY keyboard, which may be of interest for quickly typing operator names. However, there is no model of this line in current production, and I am not familiar with the functionality of the newer TI-Nspire line.

    Yes, but they're expensive; you may want consider alternatives

    \n

    Interfaces and protocols

    \n

    To understand why this is kinda a pain, we need to understand what's actually going on when we connect a monitor up to the various ports available to us. I've talked about this a bit before, but that focused on a slightly different case, so it's worth re-writing here.

    \n

    USB-C

    \n

    USB-C is a specification for a physical connector type (like USB-A, USB-B, mini USB, and micro USB), not a protocol in itself. While the physical connector does allow/limit what can be carried, it does not in itself specify what is carried. USB-C can carry (or not carry) USB data (ranging in speeds from 2.0's 380 Mb/s to 4.0's 40 Gb/s (upcoming)), power, or any one of the display-oriented "Alternate Modes" (DisplayPort, MHL, HDMI, and confusingly, Thunderbolt Alternate Modes respectively.) These alternate modes are how most inexpensive USB-C dongles work, as they allow almost entirely passive operation. Even dongles such as Anker's 7-in-1 that have separate power passthrough and data ports still use this mode, using a sort of internal USB hub to support the multiple USB devices while directing display functionality to the HDMI port. As a consequence, the data port on these devices cannot be used to output separately to another display, as the alternate modes only carry signaling for a single display (more on that later.) While you may be able to get the displays to mirror, they definitely won't act as separate displays.

    \n

    Thunderbolt

    \n

    Thunderbolt is... complicated. However, for the purposes of what we're doing, we can focus on a few main things. First, unlike USB, Thunderbolt supports daisy chaining for up to six devices; however, it does not support hubs. Second, although Thunderbolt 3 uses the USB-C port, it does not use the alternate modes to carry video, and instead embeds its own DisplayPort stream alongside the "main" PCI-e data stream. As a result, we can use a Thunderbolt hub with multiple displays. Unfortunately, the hardware required to support these devices is way, way more expensive; the specialized nature doesn't help costs either.

    \n

    Aside: USB 4 is effectively Thunderbolt, but handled by a different standard organization. Since your particular computer has Thunderbolt, I'll be using the term here, but you can consider them to generally be interchangeable.

    \n

    In terms of options, I'd recommend either the OWC 14-Port Thunderbolt 3 Dock, the Cable Matters Thunderbolt 3 Dock, or one of Kensington's various docks (potentially the SD5300T, as it's the cheapest and has requires no HDMI adapter.) They're all about $200, and they all fit the basic requirements (charging, HDMI/DP and USB-C video output), so it's just a question of what extra features you want (max power delivery, audio out, number of Thunderbolt ports, number of USB ports, SD connectivity, Ethernet, etc.

    \n

    It's at this point thought that you might notice that the video outs on these hubs vary a bit\u2014yet they all say they support HDMI, even if they have no physical HDMI port. It's time to talk about...

    \n

    DisplayPort

    \n

    DisplayPort is a video interface connection and the underlying video carrier for Thunderbolt and most USB-C-only displays. DisplayPort also contains two important features:

    \n\n

    So what does this matter? Well, the first means that any can use a DisplayPort port (including Mini DisplayPort) or Thunderbolt port as an HDMI output; if the dock you want doesn't have HDMI, don't fret. The second means you'll need to be careful choosing, as you'll only have a maximum of two display outputs (one HDMI/DisplayPort/USB-C and one daisy-chained Thunderbolt.) Basically, you'll need at a minimum need 1x USB-C out (for your portable display) + 1x HDMI/DisplayPort out (for you normal display.) Some example configurations that would work:

    \n\n

    DisplayLink

    \n

    I know you already mentioned that you don't want to use this, and I agree\u2014albeit for different reasons. Still, it's worth going over.

    \n

    DisplayLink, unlike the other things mentioned, uses a software solution to push a display signal over a normal USB interface. While this does solve the need to get another dedicated display signal and would allow you to use a cheap adapter like the Anker one linked earlier, DisplayLink comes with some annoying restrictions:

    \n
      \n
    1. You need a driver, which requires the OS to be up and running correctly as well.
    2. \n
    3. The performance, while not awful, isn't good. Lag (in my experience) is very noticeable even in day-to-day use, in the multiple 100ms range.
    4. \n
    \n

    While I'm sure the orientation problem is fixable, these issues are not. As such, I'm going to agree that staying away from DisplayLink\u2014even though the cost is very minimal due to the included solution\u2014is a good idea.

    \n

    eGPU?

    \n

    Sidenote: I'm assuming you have an Intel based MacBook Pro, as Apple Silicon devices currently don't support eGPUs.

    \n

    Given how expensive these Thunderbolt hubs are, there's one other option. Basically, an eGPU is just an external graphics card connected over Thunderbolt. This has some advantages and disadvantages:

    \n

    Pros:

    \n\n

    Cons:

    \n\n

    However, in your particular case, there's an additional complication: the USB-C port on your monitor. Unfortunately, most graphics cards don't have a USB-C port. There are a few cards which implement VirtualLink, a proposed USB-C alternate mode that isn't quite the same as the other standardized Alternate Modes, but from a practical standpoint, is often largely compatible. So far though, the only graphics cards with USB-C ports are select Nvidia RTX 2000 and AMD Radeon RX 6000 cards. Unfortunately, Nvidia cards haven't been compatible with macOS since High Sierra (before the 2000 series debuted), and all RX 6000 series cards are out of stock everywhere due to supply issues. Additionally, the RX 6800, the cheapest compatible card currently available, retails for $579, with scalpers currently asking $850+. Yikes.

    \n

    Still, if you can benefit from the performance and if you're willing to either wait for cheaper cards or pay the price, I'm going to recommend getting an eGPU. Between the increased performance and additional outputs, it offers a much better upgrade path\u2014assuming Apple adds eGPU support for Apple Silicon. Given the limitations though, I understand if that's not your ideal path.

    \n

    Buy another monitor?

    \n

    Stupid as it may sound, you can get a pretty reasonable monitor for $200. Unless you have a real love for your ZenScreen, you may be better off getting another monitor\u2014either a desktop one, or a different portable one.

    \n

    In terms of other portable displays, I see two main options: 1. Get another dedicated display that has the option for separate power and data channels (likely USB-C for power and HDMI for data). 2. Get an iPad and use Sidecar (or, if you want to use an older model, Duet Display.) Again, I'm going to dismiss using a DisplayLink monitor for the reasons outlined earlier.

    \n

    Two cables

    \n

    Okay, yeah, this one is really dumb. Still though, it'll get you the full performance while costing next to nothing, since all you need is a cheap passive USB-C dongle with HDMI and power passthrough\u2014of which there are tons. Yes, it's not as elegant having one cable go to the ZenScreen and one to everything else, but when faced with the proposition of spending $200, maybe it's an okay trade-off.

    \n

    Conclusion

    \n

    First, props for reading this whole thing; I know it's a long one, but unfortunately, this stuff is kinda a mess. Unfortunately, the standard are complicated, and everyone made different trade-offs with different goals in mind. What exactly is the right solution for you is going to vary; however, I hope this can at least set you on the right path. If you have any further questions, please feel free to leave a comment and I'll be happy to help more.

    I'm looking for a desktop switch/hub/amp/splitter (whatever you want to call it), which ideally outputs to 7.1 surround 3.5mm jacks (the green, orange and black ones - not sure what the official name for this is).

    \n

    My base use case is that I want to have a second line to my computer speakers so I can plug my laptop in when I'm using that, so as a minimum I need a 2-in, 1-out arrangement. But I'll happily buy something more 'heavy duty' if needed, though I'd prefer it to be not much larger than a desktop headphone amp/DAC or similar.

    At the moment, the best I can find is this (https://www.amazon.co.uk/Nobsound-Switcher-Passive-Selector-Splitter-Black-RCA-Version/dp/B07CQXRRRV?ref_=ast_sto_dp). This has the 2-in, 1-out arrangement, and I have an RCA to tri-3.5mm adapter for the speakers to handle the output. This isn't ideal though as it will lose the surround sound for the computer which is currently plugged directly in to the speakers.

    \n

    I know there will be no surround sound from the laptop (which is fine), so really all I need to do is hook in to the green line with the laptop, but if I could get this in the form of a switch/hub to swap on the fly that would be great.

    We're seriously considering upgrading (read: replacing) a small handful of workstations (desktops) for our department at work. No in-house IT, so I'm asked to do a suggestion myself.

    \n

    The workstations will mainly be used for EPLAN (including Pro Panel, 3D) and AutoCAD, which are poorly optimized and primarily running single-threaded. So most of it is fairly straight-forward, except I'm not sure what kind of GPU to put into it.

    \n

    The company behind Eplan suggests a Quadro 600 (don't laugh, it sports a whopping 640 MHz GPU clock) on their website. Which makes little sense, since that card was released 10 years ago and has been end-of-life for quite some time now. I know that specific card is more of a minimum-requirement than an optimal one anyway, so we need more power than that. Probably a little under the range of a GTX 1060, but that's primarily aimed at gaming and a bit expensive (cheapest one currently goes for 225 euros). Perhaps an RX 570? Probably still overkill and I have no experience with that series.

    \n

    We don't need to run Crysis at 60 FPS. We need some dedicated RAM, but not that much. We need 1 monitor that draws 3D relatively smooth and 2 others for secondary tasks. Preferably all on DisplayPort, but 2 DP and 1 HDMI will work fine too. Preferably something that's still in production and a good bang-for-your-buck ratio. Perhaps a professional version (with 3 monitor connections) of a GT 1030 makes sense?

    \n

    My gut tells me we need a base clock speed of 1250 MHz or higher, but I couldn't tell you why if I wanted to.

    For a work environment I would recommend nvidia quadro. Not the p600 or p620 those are likely to be too small and under perform although they would work and be the cheapest option. The previous model line goes P1000, P2000, P4000, [P5000], P6000. With price going from least to most expensive. I think the current model line right now is RTX but buying the P model ought to save you some money and would perform just fine.

    The P2000 is still a thin 1 slot card and does not require supplemental pcie power from the power supply. I would recommend either this or the P1000.

    There's the ongoing debate of geforce vs quadro, and geforce while you can often get the same performance or better for less money the quadro is business oriented and will provide stable drivers, no shenanigans, and may allow specific configuration for 3d render of graphic or CAD software whereas geforce would not. For business you typically do not worry about the 20% markup or whatever for the quadro line of graphics cards vs the consumer geforce. Getting a new card less than $180 usd that's not likely to happen. If you're running on a 19" monitor 1280x1024 then a p620 would probably be ok, but a 27" @ 2560x1440 or better then you'll be wanting a p1000 and a 4k monitor probably a p2000.

    I am looking for an active USB 3.2 Gen 1 -- or preferably Gen 2 -- hub which comes with at least ten usable ports, half of which should be USB-C sockets and the other half of which should be USB-A sockets.

    A larger USB hub will always contain multiple USB hub ICs daisy chained inside so getting a single device is not necessarily advantageous. But, searching, say, Newegg for usb 3.2 gen 2 hub finds a ton of of devices these days, that's not a problem any more.

    \n

    The problem is bandwidth. 10 ports at 10 gigabits would consume 100 gigabits and there's absolutely no way currently to get this much bandwidth. The most bandwidth you can potentially get out of a laptop is utilizing four PCIe 4.0 lanes (like from an M.2 socket utilizing a OCuLink riser with a redriver). Actually. Lenovo's new ThinkBook 14+ 2024 will feature OCuLink , the GPD Win Max 2 also has it. That's 64Gbps. The One Dock can convert that to a PCIe slot. Alas, AFAIK there no USB root hub connecting over PCIe 4.0 so this avenue while promising currently doesn't go far.

    \n

    Using more traditional interfaces, the best we can do is USB4. The ADT-Link UT3G is utilizing the ASMedia ASM2464PD and can nearly provide as much bandwidth as PCIe 3.0 x4 possibly can, benchmarks showed around 30Gbps. You can add a dual ASM3142 card like the SI-PEX20233. Each ASM3142 provides two 10gbps ports from two PCIe 3.0 lanes -- it's slightly oversubscribed but not terribly.

    Because of the nature of my work, I need a laptop with a big screen, 6-8 cores and a large battery. A network port would be good too, if possible. My budget is about 1200-2500$. But the problem is, I only either find gaming laptops with really expensive GPU's (and that run out of battery incredibly quick because of them, since they are always running) and lots of features I'll never even need or incredibly expensive design Notebooks that are way above my budget (Like the XPS 17) that often don't even have any usb ports.

    Your current laptop is actually quite decent, but as you are using a power savings CPU this is likely limiting your compile speed as mentioned.

    \n

    The class of laptop you are looking for is a workstation laptop. These are typically sold for use in specialized business contexts. Because of your requirement of no GPU due to battery concerns, this means that we are forced to throw out a significant segment of the market as Gaming laptops are usually going to deliver best bang for the buck for the specs that you desire.

    I decided to push your budget in favor of higher quality components.

    \n

    DELL Precision 7750 Workstation $2,276.67

    \n\n

    Because I am recommending a laptop you can buy from DELL directly, this configuration is customizable depending on what you want specifically. I've just pre-selected what I suspect you would desire (e.g. lowest resolution screen to reduce power consumption).

    \n
    \n

    If you are seeking to lower the price I found a lower spec-ed configuration on newegg for $1,174.99, but I could only find refurbished laptops of the 17" size variant. At that price point I didn't think you would want to shoulder the risk of the battery already been somewhat worn and therefore sacrificing your battery life. You could also try looking on Amazon, but the spec filtering on there is rather lackluster.

    \n
    \n

    A final note I would like to attach, is that if you find the performance to be sufficient, and want to extend battery life, you could try installing the Intel XTU CPU utility and purposefully shortening the turbo boost time (recommended) or try undervolting (not recommended if you value system stability). Note that voltage has a squared relationship with power consumption, while frequency has a linear relationship.

    Mh, difficult to summarize... I don't like fat bulky smart watches that only display the time when I wiggle my wrist or press a button.

    \n

    On the other hand, features like motion sensors and whatever on your wrist, and phone notifications, can be helpful at times. I was very interested when learning about the Skagen Jorn Hybrid HR smart watch (a rebranded Fossil HR Hybrid smartwatch), which still looks ok in size, an uses an always-on epaper display.

    \n

    Unfortunately, it seems to require a Fossil online account for everything, even to display local notifications from my phone, or to perform sleep recording, which is a no-go for me.

    \n

    While trying to validate whether this is true, I also learned about the Sigma iD.RUN HR, which claims to also work "offline", but does not really look like a classical watch.

    \n

    I'm not really looking for recommendations, which by nature are strongly opinion-based, but rather hints which smart watches are there at all which come close to what I have in mind (in descending order of priority/importance):

    \n
      \n
    1. Does not require an online "Cloud based" account to which it transfers data. (Fetching updates from some server is fine with me.) (Well, at least does not transfer much data during operation, even if it may require the account to set it up.)
    2. \n
    3. Looks somewhat like a classical watch, but not too bulky. Mechanical watch hands would be nice, but not mandatory. (The Skagen HR actually looks quite ok in this regard.)
    4. \n
    5. Connects to an Android phone (e.g. Bluetooth and/or NFC) and can show notifications and reminders from this phone (and maybe provide a way to dismiss those notifications).
    6. \n
    7. Time (and preferrably date) are always readable.
    8. \n
    9. Has motion sensors for gimmicks like step counting or sleep tracking.
    10. \n
    11. Has even more obscure sensors like pulse/heart rate sensor and/or blood oxygen sensor.
    12. \n
    13. Preferrably runs for a week or longer before it requires recharging.
    14. \n
    \n

    Especially information about whether a cloud / online account is required, and for which features it's needed / which data is exchanged seems to be really hard to come by. For the Skagen HR, even the tech specs on the website didn't mention the mandatory online account.

    \n", "Title": "\"Watch-like\" Smart Watch With Android Notification Support but Without Mandatory Cloud Synchronization", "Tags": "|smart-device|wearable-technology|", "Answer": "

    In the end, I now ended up with a Skagen Jorn Hybrid HR, which is technically identical to the Fossil Hybrid HR watches.

    \n

    Yes, by default it also forces you to use the Fossil cloud services - but I learned about Gadgetbridge, an Open Source and Free Software Android app which supports a whole bunch of wearables without the need for any cloud service at all.

    \n

    BTW, Gadgetbridge also supports the Pebble mentioned above, besides some Fitness wrist bands and similar devices.

    \n

    For many of the supported devices, this is supposed to work mostly flawlessly.

    \n

    In case of the Skagen Hybrid watch, this solution definitely isn't for everyone, as you need to obtain the watches' crypto key in order to fully enable its features. But if you're technically savy, it works thanks to the amazing effort lots of developers put into the software, and the Skagen then is really close to my dream solution...

    \n

    It runs about 2 weeks with one charge, has analog hands and an always-on epaper display which can show custom widgets with measurements etc. It also comes with some pre-installed apps for smartphone music player remote control, weather forecast, stopwatch and timer, and, thanks to Gadgetbridge, in addition allows custom apps and widgets to be written and installed.

    Logitech Wireless Performance Mouse MX (I own 3) has a physical button that turns "detents" on and off.

It is a large mouse. Uses rechargeable or replaceable AA battery (for me a nice feature). A third party program allows even more settings than normal. Google "uberOptions".

    \n

    The MX Master (version 1? Only tried a friends one) free-runs automatically when the mousewheel goes over a certain speed and reverts back to detented under that speed. It has a manual (non mechanical) override button too and from memory the speed threshold can be set. (called Magspeed). At the time I tried it (18+? months ago) the setting software was a new system and annoyingly dumbed down... they claimed they were going to add features, but I don't know the status now. Used a proprietary rechargeable battery, advantage longer use time, disadvantage you can't just pop another battery in when it dies on you.

    Logitech has a "Smooth Scrolling" plugin for Firefox, but it didn't work well for me when I first tried it over 2 years ago (apparently conflicted with my 3D mouse). Also, apparently doesn't work with their gaming mice.

    If you connect everything up through HDMI, it should work fine. I myself only use one optical connection from my TV to my receiver, because my receiver pre-dates HDMI. So the audio data from my PS4 goes through HDMI to the TV which passes it through the TOS-link to the receiver. I haven't encountered any problems with codecs. All codecs that the receiver supports work and otherwise it just falls back to PCM channels.

    One of the more important features that a hard drive can optionally support for RAID is TLER or CCTL. When a drive doesn't have this it may lead to false-positive critical errors showing up in the NAS when a drive takes just a little too long to respond. (So the NAS thinks it's dead.)

    In short: I\u2019m looking for a hardware/software solution to handle an amount of data, which should be accessible from multiple devices including iPhone and protected from unauthorised access.

    \n

    In detail:

    \n

    I\u2019ve got a file repository of some 500GB with that I want to check in from once a day to several times an hour. Most of the data is confidential, so I can\u2019t carry it around on an unprotected USB stick.

    \n

    I want to access the repository from any of my devices, namely two Windows 10 PCs (home and work), a Windows 10 laptop and necessarily iPhone 11 Pro. (If no iPhone were involved, then the task would be trivial.)

    \n

    The repository must be accessible regardless of the Internet connection, so cloud storage isn\u2019t an option. The solution should probably include a physical storage device that I can keep on hand.

    \n

    The data must be protected with a password I need to enter exactly once per connection to a device. E.g., so that I can connect the repository to iPhone, then enter a password and gain full access to the data without re-entering the password until disconnected.

    \n

    I also don\u2019t want a physical combination lock, fingerprint scanner, etc. on storage device; only a regular old-school password to enter on a PC or iPhone to which the device is connected.

    \n

    I\u2019ve tried an iDiskk device that can work as an external drive for iPhone, but it doesn\u2019t support password encryption.

    \n

    There might be some kind of specialty adapter that can connect a regular external SSD to my iPhone and works with a dedicated app, but I haven\u2019t found one.

    \n

    So I would appreciate your suggestions.

    Since I got no response on a few dozen of discussion websites (not only here), I had to do my research, and here\u2019s the result.

    \n

    I was able to connect an encrypted USB flash drive to my iPhone and manage files on the drive. The general appearance of the solution is shown on the picture:

    \n

    \"Connecting

    \n

    The effect is determined by several factors listed below.

    \n
      \n
    1. iOS version. According to Apple, external drives in Files app are supported since iOS 13.0, and support for encrypted drives was added in iOS 14.0 (see Files section in both sources). I\u2019ve used iOS 14.6 on iPhone 11 Pro A2215 (MWC72RU/A).

      \n
    2. \n
    3. External storage device connectivity options. I\u2019ve tested several USB devices, and I\u2019ve no information about other connection types (e.g., SATA or Bluetooth).

      \n
    4. \n
    5. The device\u2019s USB version. All my storage devices were USB 3.x, and I don\u2019t know if USB 2.0 is going to work, too. I picked out the relatively old Kingston Data Traveler HyperX 3.0 (256GB) for this example.

      \n
    6. \n
    7. A way to physically connect the storage device to iPhone. I\u2019ve used Lightning to USB 3 Camera Adapter, and it seems to be the only adapter that can work in my case. The name of the adapter is quite misleading because you can use it not only with a camera, but with other external devices as well.

      \n

      The adapter has two ports: USB 3.0/3.1 Gen 1 (for connecting an external device) and Lightning (for powering it, if necessary).

      \n
    8. \n
    9. Powering. After connecting a device, you might see the message: \u201cThis accessory requires too much power\u201d.

      \n

      \"This

      \n

      That means you need to connect a power source to the Lightning port but beware of the pitfall: not every power source is going to suit. For instance, a 63W Belkin adapter (WCH003vf) that I usually use to charge the iPhone didn\u2019t work for me. But an original 20W USB-C Power Adapter with an USB-C to Lightning Cable did the trick.

      \n

      I didn\u2019t look more into this issue, but it\u2019s surely not about wattage.

      \n
    10. \n
    11. Organization of data on the storage device. I tested devices of the GPT partition style only, and formatted them to FAT32, exFAT and APFS (case-insensitive), with exactly one partition occupying the entire device. In all cases, the devices were accessible from iPhone just fine when unencrypted. The device is showing up in the Files app (it\u2019s named Kingston in my case). Encryption works in APFS only, and iPhone prompts for a password.

      \n

      \"An \u00a0 \u00a0 \u00a0 \u00a0\"iPhone

      \n

      I think case-sensitive APFS would also work, although I haven\u2019t checked.

      \n
    12. \n
    \n

    Formatting a storage device to APFS with encryption can be tricky if you don\u2019t happen to have a Mac at hand, but I was able to do with macOS in a virtual machine.

    What is the difference between an LED and a lamp? If they are different, how can I tell if a component is a LED or a lamp?

    \n", "Title": "What is the difference between an LED and a lamp?", "Tags": "|led|", "Answer": "

    there are a lot different Lamps, see https://en.wikipedia.org/wiki/Lamp for "Lamp (electrical component)\nLED may be used as for "LED Lamps" or for the electronic part.\n=> A lamp may contain a LED.\nA Lamp can be light bulb, vacuumed, with a special wire, glowing if voltage attached to the light bulb. A lamp usually has a socket - and a defined operating voltage.

    \n

    To recognize it as LED Lamp:

    \n
      \n
    1. Look - a LED lamp needs a electronic circuit to work. it is usually inside the socket, older ones have a white part between the socket and the glass, newer ones look like older light bulbs, but the "glowing wire" is a yellow or orange led wire - see https://en.wikipedia.org/wiki/LED_lamp for examples.
    2. \n
    3. Efficiency - Wattage written on the bulb - A LED Lamp usually has a low wattage for a high Light emission e.g. 6 watts for 500lm instead of 60 watts light bulbs
    4. \n
    5. Heat emission - LED will not heat your hand if you are near as 2 to 10 inches (one reason for their efficiency).
    6. \n
    \n

    If the wattage is not printed, you may use a energy monitor (a device as wall plug providing a socket and a display) but the heat dissipation will be much more with a glowing light bulb as with a LED.\nNote: A LED also emits heat but usually not hot enough to boil a drop of water.

    With only a 3080, your system would draw around 550W. Add 200W for the 3060ti, and you get 750W. If RTX 3000 series would not have mega power draw spikes and nothing is OCed, 750W is just enough for you. Because RTX 3000 series have mega power draw spikes, I would reccomend going at least 200W above that (+-1000W).

    \n

    Also, to stay under that 1000W mark, try undervolting your graphics cards a bit in MSI Afterburner. It should not impact performance, it can even improve performance and it reduces power usage.

    \n

    For power supply brands, I would reccomend Corsair and Seasonic.

    By using higher base clock RAM, the Infinity Fabric speeds increase. Causing an overal performance increase of the CPU itself.

    You can, but if you don't use 90+% of your ram, it should not impact performance. You should buy a 16GB stick (or a 1*16GB kit) with a 2667Mhz speed. To make it fit in the socket, use DDR4 SODIMM. To ensure the best compatibility, try buying the same stick that is already in your laptop (google Kingston ACR26D4S9D8ME-16). To install the ram stick, you can use the instructions given by @MANAV of see if the laptop manufacturer has a video explaining how you can upgrade the ram.

    I have an entry-level gaming laptop with an NVIDIA GeForce GPU and I like to cap the few games that I play on it to 60 fps. Would an expensive gaming monitor that can handle refresh rates well beyond 60 Hz be (1) a waste of money and (2) problematic? I've read that using an overpowered monitor on a relatively underpowered GPU may cause performance issues. However, can't I just buy a G-SYNC capable monitor and have the NVIDIA GPU bring the monitor's refresh rate down to 60 Hz when I play games?

    \n", "Title": "Would a G-SYNC monitor prevent performance issues for underpowered GPUs?", "Tags": "|monitors|", "Answer": "

    I think you've misunderstood what people mean.\nThe refresh rate of your monitor has no impact on gaming performance. It only decides how often your monitor can show a new frame every second.\nWhat can impact performance is monitor resolution. However you can always choose to render a game at a lower resolution and let it upscale. Or use Nvidia DLSS if availible.

    \n

    You also do not need a G-sync capable monitor for this, especially considering that with a G-sync monitor the monitor refresh rate is dynamically ajusted to the framerate of your game. Basically already dynamically doing what you are asking. If you then limit the maximum refresh rate. you're only denying yourself extra visible frames if they are availible.

    \n

    However if you really wish to reduce the refresh rate of your monitor for other reasons you can do this by right clicking on the desktop and selecting display, then scroll down and click 'advanced display settings' there is a drop down to edit the refresh rate.

    I've shortlisted 3 entry level scanners of my budget.

    \n
      \n
    1. Epson Perfection V39
    2. \n
    3. Canon LIDE 400
    4. \n
    5. Canon Canoscan LIDE 400
    6. \n
    \n

    I'm not really sure if LIDE 400 and Canoscan LIDE 400 are same or different, but I couldn't find any difference other than dimensions and a sticker printed on one of them.

    \n

    Canon India refused to tell if both are same and different. They were saying both are same. Only one of them is listed on Canon India website (i.e., Canon LIDE 400) They said contact Amazon. Amazon told me that both have different sellers and seller is sending under different name. But the MRP price difference of Canoscan is almost double on Amazon.

    \n

    But anyway, I did my research and I couldn't find single difference between them. Because I was able to find Canoscan on Canon UK website and its specifications were same. So I am assuming they are same just sold under different names. I don't have proof though.

    \n

    Now, all 3 have almost similar specifications. Same sensor, same DPI and same document size.

    \n

    I didn't go into extreme details but I compared basic details which I should know and which I understand.

    \n

    Now I can't make a decision. The thing is, on Amazon India, Epson V39 has better reviews. Canon LIDE 400 has a bit less good reviews. However, like I had said, Canoscan LIDE 400 is also listed on Amazon India, which has better reviews.

    \n

    So overall, I feel people are doubtful about Canon LIDE 400 or Canoscan LIDE 400.

    \n

    Which makes me feel V39 is better. I read many articles/videos online, which also listed LIDE 400 slightly better than V39.

    \n
    \n

    What I would scan is mostly A4 size pencil drawings on Bristol paper. Or A5 paper. Sometimes A3 paper (I know A3 is not supported but I would use multiple scans and later combine them). So main focus is A4 drawings. On rare occasions, colored photos and maybe paintings.

    I would go with Canon since they also make cameras and that expertise might go into their scanners. They probably both perform the same if they are the same price since scanners are a commodity item and are not obscuring their quality with luxury pricing.

    With SSDs, assuming all else is equal - same speed, size etc, then there is no speed advantage in having two separate drives.

    Instead you have an element of redundancy. If one fails, you still have the other - less 'eggs in one basket' syndrome.

    As both OSes are not going to ever be running simultaneously, I'd see this as the only real advantage. [you could belt & braces further by having recovery for each on the other drive], though you would presumably have both backed up externally anyway.

    SSDs don't care 'where' data is on a drive - they don't map partitions to actual physical locations like an old spinny rust HD - so unless you're running them too full [over 80% consistently] then I don't see wear being a decider either way.

    With the end of working in offices. I tend to work in coffee shops and I have a tablet that I bring as a second screen.

    Another idea: if you have a Samsung Galaxy S8, Note 8 or newer, (a quick way to check is to see if you have a USB type C charging port. If you do, your Galaxy is compatible) you can use Samsung Dex. This uses a USB C to HDMI adapter (such as this one) to output an HDMI signal to a monitor and uses your phone as the trackpad/keyboard.

    I'm looking for a temporary & budget PC for software development (JS with VS Code).

    \n

    I found attractive and comparable in terms of price used PC models with i7-4790 (HP 800 G1 SFF) and i5-6500 (HP 800 G2 DESKTOP). Both of them seem to meet my requirements.

    i7-4790 has higher clock speed (3.6-4.0 GHz vs 3.2-3.6 GHz), more threads (8 vs 4), more cache (8MB vs 6MB) than i5-6500. The only parameter it seems to be worse in is supported RAM which is DDR3 vs DDR4 of i5-6500. But this seems od little importance for my use case. Also in various benchmarks i7-4790 seems to visibly surpass i5-6500, eg, but not only:\nhttps://cpu.userbenchmark.com/Compare/Intel-Core-i7-4790-vs-Intel-Core-i5-6500/2293vs3513

    \n

    The upgradebility seems to be not a factor, because the motherboard for 4790 will not support 4790k and the one for 6500 will only support i7-6700 which seems to be on par with 4790 in benchmarks while being more expensive. \u200b

    I've started making a list for a new build I'm doing, since my current desktop is starting to get some problems. But getting to the CPU, I'm really split about the choice of CPU. I've decided that I'm most likely gonna go with an Intel core I7, but I can't decide if I should go with the 10th or 11th gen, and I also can't decide if I should go with the K or KF model. As far as I understand the only diffrence between K and KF is that K has integrated Graphics and KF doesn't, but then KF is slightly cheaper.

    \n

    Is it just a waste of money to buy K instead of KF since the build will include a GPU? And is the difference between 10th and 11th gen, enough to make up the difference in price?

    Everything seems fine but I would suggest you to go for an AMD CPU instead of the intel one.

    \n

    AMD competes toe to toe with intel in most games and surpasses intel in a lot of games as well. Also AMD is better oriented for a professional workflow like rendering etc. The 5800x even has a lower TDP than the intel 11700k.\nAlso make sure that the cooling is sufficient, you would probably need an AIO for the same if not a good dual tower air cooler like the Noctua NH D15 or bequiet Dark Rock Pro.

    \n

    If you are absolutely going with intel then I don't find much merit in getting the 11th gen over 10th gen for games. But in cases of workflows like rendering etc 11th gen would give a bit of an advantage. KF is a better choice if you have a GPU available at hand, but if you dont then you wont be able to run your PC until you get a GPU.

    EDITED:

    \n

    I recently upgraded the screen of my computer, which was an HP 2229h from about 10 years ago, to a much more recent and better screen: an AOC U32E2N (https://eu.aoc.com/en/products/monitors/u32e2n).

    \n

    This new monitor can operate at a much higher resolution. However, I have noticed that the monitor refresh rate (connected with DisplayPort) is at 29Hz instead of the 60Hz that were set with the old monitor.

    \n

    This monitor can handle 60Hz so the monitor is not the problem. The cable can too, I bought it on purpose. Hence, I have two questions:

    \n
      \n
    1. could my the graphic card (NVIDIA GTX 570) be the limiting factor in the refresh rate?
    2. \n
    3. if not, would it be the CPU or the motherboard?
    4. \n
    \n

    I have a quite old motherboard and a quite old graphic card. Both, however, did the job quite well until yesterday. I am not a heavy gamer anymore so I don't need an ultracapable hardware graphics-wise. I make music on my PC though and that requires a lot of CPU.

    \n

    Which one would you update first, why, and with what if have any suggestions?

    \n

    Here are my specs:

    \n

    Graphics card: NVIDIA GeForce GTX 570

    \n

    Screen resolution: 3840 x 2160

    \n

    Motherboard : ASUS P8H67

    \n

    Processor: Intel i5-2550K, 4 x 3.40GHz

    \n

    RAM : 8 GB DDR3

    \n

    Operating system : Windows 10 (x64)

    \n

    According to PC-specs: "Released on 29 Dec 2010, the Asus P8H67 is now over 10 years old, which means it is extremely out of date and is based on very aged technologies."

    \n

    Also my graphic card turned 10 this year. Hence, I would like to know which one in your expertise is the main culprit of slowing everything down with the resolution increase. I suspect the motherboard, but I'm no IT engineer.

    The GTX 570 is too old to have a DisplayPort that can handle 3840x2160 at 60hz.

    You can easily tell if your CPU is the limiting factor by looking at the CPU usage in Task Manager. If the whole CPU or a single core is at 100% while performing a task, a faster CPU would do better. If not, then more information is needed to determine what is slowing things down.

    A GPU is kind of like a whole sub-computer on its own add-in board.

    \n\n

    Keeping all of that in mind, these factors all affect performance in different ways and the performance will vary depending on the program you want the system to execute. This is true for both CPUs and GPUs. A benchmark only tells you how fast that program will run. A different program will have different performance.

    \n

    Ultimately you cannot know ahead of time what GPU is best for your OpenCL code unless somebody has already run that specific code on the GPU and benchmarked it. Every OpenCL program is going to utilize the GPU in a unique way. If your program does lots of simple floating point operations in parallel with the bare essential memory I/O, it will probably end up running better with the GPU that has a better theoretical FLOPS benchmark. But programs are never that simple, so FLOPS measurements are useful as an upper bound for performance; Not an average.

    There is no surprise here, things that run on the SSD run at the SSD speed. Things that run on the HDD run at HDD speed. But since there's more stuff using power in the laptop the battery will be drained quicker. HDDs can conserve power by going to sleep if you make sure they're not being used in the background.

    Most computers parts, unfortunately, are being built for a rather short period of time these days... as you just found out.

    For memory to be compatible, you want to find a replacement which has at least the exact same number of pins (like 288), speed (3000Mhz), and technology (DDR4).

    Further, there are features such as ECC which, if not present on one stick will not work at all (as far as I know) and at times can generate issues (i.e. "break" the memory).

    A good idea is for you to check your motherboard memory compatibility chart. However, it's likely that they would not have updated it with newer sticks... so it's probably not going to be that helpful.

    \n

    Finally, if you plan to keep the old stick, you can test with one new stick and if it looks like you can use one or the other but not both together, then purchase a 2nd of the same new model and that should work together. It makes it a bit more expensive (unfortunate), but probably better than not being able to increase your RAM at all.

    \n

    In terms of speed, like others said, it won't per se go faster since your CPU will remain the same. However, you will indeed be able to run more software together and avoid swapping to disk, which is definitely a great way to make things go faster on your computer (i.e. you don't have to close/re-open things all the time).

    There is another risk with a second network card though, they all (afaik) use PCIe 1x. That means that if you want 10gbps, you need to plug it in a pcie 3.0 or 4.0 slot, and those are only the 16x and m.2 slots on cheaper motherboards (like my B450m a pro max from msi)

    With Blender, probably none, because its done fully on CPU, or fully\non gpu. So if you set the render target to CUDA, it will have gpu speeds, no matter of your CPU speed.

    CPU frequency is not a measurement of performance. Your Intel i5 Y-Series has aggressive power management maintain strict thermal limitations. The 3.6 GHz turbo speed will only briefly be obtained, most of the time the CPU will be at a slower clock speed. Turbo is not loke overclocked speeds where it is always at the higher clock speed.

    Okay so I had finalized ryzen 5600G APU because I can't afford GPU at the moment. So I'll add a GPU after couple of years when it get cheaper.

    \n

    So far, I had read that there's not much difference between 'Processing' performance of an APU and equivalent CPU.

    \n

    For example, the 5600X CPU. It is same as 5600G but just lacks an integrated GPU.

    \n

    Now, I just read following things somewhere - Pros and Cons of APU:

    \n
    Pros:\n\nSmaller size - In form factors without enough room for a GPU, an APU is quite discrete.\nSize to power - For they're size, they're impressive!\nCrossfire capable - GPUs can be added in crossfire for upgradability.\n\nCons:\n\nLess power - APUs can't pack the same punch as a GPU.\nShared memory - APUs use the same memory for CPU and graphics, limiting the amount.\nLimited GPU crossfire options - Not everything works with these.\n
    \n

    I quite don't understand what he meant by crossfire, but in the 3rd cons, he said limited GPU crossfire options. Not everything works with these...

    \n

    So what I've concluded from this con is that 5600X will have more options of compatible GPUs (when I will upgrade) whereas 5600G will have less options available of compatible GPUs. (This is what I've concluded. I don't know the reasons, if any, for this)

    \n

    For example, it could be possible that 5600X supports 10 different GPUs. But 5600G will support only 7 of them.

    \n

    So is it true for these processors?

    \n

    I can make my final buying decision based on only this. If there's no compatibility issue, I'll go with 5600G otherwise I'll buy 5600X and a cheap separate GPU.

    \n

    So which one should I buy given that I don't want compatibility issues later?

    \n", "Title": "Should I buy APU or CPU keeping in mind I will add a GPU in near future", "Tags": "|graphics-cards|motherboard|pc|", "Answer": "

    Most modern CPUs are "APUs" and I actually recommend getting something with onboard graphics. 5600G is a better option here.

    \n
    \n

    I can't afford GPU at the moment

    \n
    \n

    This is a great reason, especially in the great everything shortage to get a CPU with a decent onboard GPU.

    \n

    I have an older/worse/laptop grade ryzen and... those things don't too bad, and even hold up well with casual gaming. I'd second Irsu's suggestion of getting dual channel ram, and the fastest you can afford

    \n

    To start with - while setting up, and in future, it gives you a 'known good' graphics output for setup and testing.

    \n

    "Crossfire" and "SLI" are vaguely obsolete and are ways to "tag team" two identical CPUs. The 'replacement' for it is explicit multi GPU. This is not a factor here.

    \n

    The integrated GPU can be disabled if a discrete GPU is in (or kept enabled) - in windows 10 and better, you could, in theory, set some applications to use the integrated GPU specifically for various reasons.In my case, I run additional monitors off my onboard graphics.

    \n

    There's no downside, or compatibility issues with a integrated GPU other than that "you're potentially paying a little bit more for silicon you arn't using". In this case, it feels like a much better option than buying a "cheap" and probably overpriced GPU you're going to not need when you get your proper GPU.

    I've been looking around for VRMs, and some of them mention being 'Digital VRMs'

    \n

    What is the major difference? What are the advantages/inconveniences with having a 'Digital VRM' instead of a 'normal VRM'?

    \n

    Or is the 'Digital VRM' thing just a marketing ploy?

    \n", "Title": "What is the meaning of a 'Digital' VRM solution?", "Tags": "|motherboard|", "Answer": "

    First, for those stumbling across this question who don't fully understand what the VRM's job is:

    \n

    A VRM is a fine-tuned DC to DC power supply for voltage-sensitive electronics like a CPU or GPU. It usually has multiple "phases" that it switches between to ensure that the average voltage output is stable, and so that the components don't have to work for 100% of the time and overheat. (4 phases means each phase is supplying power 25% of the time)

    \n
    \n

    What is the major difference? What are the advantages/inconveniences with having a 'Digital VRM' instead of a 'normal VRM'?

    \n
    \n

    Modern CPUs can decide how much voltage they need to get a certain task done, or to help itself cool off. They tell the VRM to provide a target voltage over a digital connection. This allows the VRM to use a feedback loop so it can control itself based on its own output versus the target output.

    \n

    On an Analog VRM, the target voltage is compared to the actual voltage in an analog circuit that uses transistors. It is designed to always adjust voltage to make the difference between the two signals be as close to 0 as possible. This is an older/simpler design and works just fine. In fact, analog systems can be very accurate and still show up on "high end" motherboards.

    \n

    On a Digital VRM, there is a microcontroller that reads all of the voltage values in digital and uses algorithms & math to set the output voltage. Normally using a PID controller. The microcontroller allows the VRM to be "smarter" about how it outputs voltage and may be aware of other conditions in the system to better manage the power.

    \n

    Generally speaking, analog VRMs respond faster and are cheaper to make.
    \nDigital VRMs are very complex and require a lot of tuning work to make them effective; But if they are designed properly they can do the job well while also providing many extra power management controls or features. (In the BIOS or motherboard software)

    \n

    In either case, there can be poorly designed VRMs that do not perform well, and really high quality VRMs that can handle extreme overclocking. There is no general answer to which is better.

    There are many options here, the question you have to ask yourself is how much work do you want to put into it?

    \n

    A NAS is essentially a full computer that is self-contained in a nice little enclosure. You can either get one of the premade ones like the Synology one you mentioned, or build your own, or simply connect them to an old computer and share the hard drives with Windows SMB.

    \n

    I will say this, the Synology one will be much easier to configure and manage. The DSM management software is very well made, just a point and a click to accomplish most tasks to get your stuff running.

    \n

    As for the hard drive enclosure connected to your router, that depends on your router. Are you asking about an external enclosure to a router's USB port? If your router supports sharing external storage via its USB port, then yes you could. If it only supports DLNA then it won't work as a full NAS. You'll have to check with your router specs to know for sure.

    \n

    I use an external hard drive dock to connect my HDDs to my computer.\nFrom there, you could SMB or NFS share them on your network and devices could access them, but only when connected to a computer. Again, an old computer laying around would suffice if you really wanted a NAS. But the Synology would be the better option in my opinion.

I use my laptop for all kind of tasks (also editing videos, rendering etc. but not like crazy...). So I was wondering, how I keep the drive in a good temperature (mainly the controller).

    I was thinking of a thermal pad as cooling support. I was reading several times that the Samsung Evo 980 Pro tend to get warmer than other drives.

    The label of the Evo 980 Pro seems to have a cooling effect. Should I remove the label still or add a thermal pad on the label?

    You can keep the label. If it assists cooling, it should transfer the heat to the outer heat sink (normally air or something built into the motherboard). If you want your laptop chassis to be the ssd heatsink, you can add a thermal pad on top of the ssd. BTW, that is also how some modders made Macbooks a lot faster (M1 and intel based)

    I took apart the battery and brushless motor from my e-skateboard and want to use it in my own project.

    \n

    \"batter

    \n

    \"motor\"

    \n

    \"remote\"

    \n

    And here is the product manual if it helps.

    \n

    I really want to re-use the existing hardware, i.e. battery, ESC, motor and or maybe the remote so that I reduce the cost of this project.

    \n

    But once I took apart the battery and found there is no interface/socket for me to connect the ESC PCB connected to the battery to my RPi(if anyone could figure out how to connect this ESC to RPI, I'd love to hear about that), then I have 2 solutions to get the battery and motor work with my RPi.

    \n
      \n
    1. buy an ESC and use it to connect to battery and RPi and control the motor
    2. \n
    3. hack the remote to re-use everything
    4. \n
    \n

    The most preferable approach is to re-use the existing ESC but I think it's too hard as I mentioned before there is no interface/socket to do that.

    \n

    Then my 2nd preference is the option 1 as option 2 is hacky(because I need to use 2 of these set of hardware for the 2 rear wheels and not sure whether the 2 remotes will interfere each other, also the remote requires charging).

    \n

    So if I go with option 1, I will need to know what's the voltage, operation current and peak current of the motor.

    \n

    From the picture I show above, I can see the battery voltage and its current which are 24V, 2.2Ah. Also from the manual I can see that the watt for motor is 150W. From these information, will I be able to confirm that the Motor also uses 24V and 2.2 A current?

    \n

    I want to proof my thought by measuring the motor.

    \n

    But the problem is the motor has 3 cables, so how am I going to measure its voltage and peak current?\n(Btw, I have multi-meter)

    \n
    \n

    Update:

    \n

    I use multi-meter and checked the battery's voltage: 28.27V.\nAlso searched the battery against its model GB T 18287-2000 and found this:

    \n

    \"enter

    \n

    Here is the link to this PDF, table is on the page 2.

    \n

    As it mentions, the Charging/discharging (fast) is 30A *3.5h,\nthe Pulse discharging current (max) is 180A.

    \n

    Not sure whether is this the max discharge current or not?

    \n", "Title": "How to detect the voltage of a brushless motor", "Tags": "|battery|", "Answer": "

    A few misconceptions for your device. The battery voltage is 24. The capacity is 2.2 ampere-hours, not 2.2 amperes. This (Ah) is the equivalent of the size of your gas tank, while a current measurement (A) would be more representative of the size of the pipe from the gas tank to the engine. Bigger pipe, more flow, but that's not important.

    \n

    You have three wires to/from the motor. These devices are typically considered brushless DC motors, also called three phase motors.

    \n

    The motor controller takes user input and converts it to pulses to the motor, in the correct frequency and the correct order to create the desired speed and direction.

    \n

    You can expect that the motor has a voltage range rather than a specific voltage, but applying a voltage that is too low will provide insufficient power to move. Applying a voltage that is too high will certainly move the wheel/motor, but going too high means heat. Too much heat is bad.

    \n

    With a 24v battery, using that figure as a baseline is a good start. One of my brushless motors is rated to 36v, but the manufacturer explained that the motor had sufficient components to handle 48v but I'd have to get an appropriate controller.

    \n

    You can easily locate a 24v brushless controller, aka ESC, electronic speed controller and a servo tester to experiment with the motor. Your current figure should be checked at the battery, as the three leads for the motor are going to have pulsed current and will not be easily read with a digital or analog meter. One could determine useful information with an oscilloscope, but that's not part of the question.

    \n

    With respect to the current draw, you've noted that the motor is 150 Watts. 150 divided by 24 is approximately 6 (amperes) at maximum power. Your ESC should be rated higher than that and a ten ampere ESC gives you some leeway.

    \n

    The battery does not have a label indicating C rating (maximum discharge current) but it's safe to consider that 6 amperes (maximum) current draw (slightly less than 3C) is within normal limits.

    \n

    One should aim to limit discharge of a lithium chemistry battery to no more than eighty percent depth, providing for (2.2 x 0.8) 1.76 ampere hours capacity. Pulling 6 amps at maximum current provides for somewhat less than 20 minutes operating time. This also matches with the battery marking of 52 WHr on the label. 150 Watts motor power divided by the approximately 50 WHr figure gives you one-third of an hour (20 minutes). It's unlikely you'd be operating at full current and for the purposes of this answer, 3 amperes current gives you about 40 minutes operating time between charges.

    \n

    Consider also to install a current measuring/counting device such as a watts-up meter to the battery of your new construction. This provides you with instantaneous current reading but more useful, it provides total ampere-hour consumption. You can zero the device after the charge is complete, and check it regularly during use of the device, ceasing to enjoy your ride prior to reaching the 1.76 ampere-hour threshold.

    Unfortunately, the laptop I'm using only has USB 2.0 ports, which really slows down data transfer rates to this external hard drive:\n\"enter\nSamsung Portable SSD T7 USB 3.2 1TB

    \n

    Fortunately, the laptop does have an eSATAp port which is capable of very fast transfer rates. So, on Amazon, I searched for a USB C to eSata adapter.

    TL;DR: I don't think what you are looking for exists; And if it does it still won't work for your Samsung drive.

    \n

    USB can support communication with pretty much any device as long as that device implements the USB protocol and the host PC has a driver to go with it. There are all kinds of devices out there that connect SATA drives to USB ports by wrapping the SATA drive messages inside the USB messages. (See UASP)

    \n

    SATA is an entirely different kind of data bus that is highly specialized for storage devices. The messages being sent out of the eSATA port on that laptop are in a language that USB devices don't understand or expect to receive over the wire. Also, there is no such thing like a "USB message wrapped in a SATA message", so USB clients can never be connected to a SATA port.

    \n

    If an adapter like this existed it would be very complex and probably introduce a lot of opportunities for data corruption. It would have to emulate what the device on each end expects and convert the content of the messages between the two protocols.

    \n\n

    In the end, even if the adapter did exist, you're trying to connect a drive that doesn't even use SATA! (The Samsung T7 uses NVMe storage technology)

    Maybe you can find a projector that will connect to your NAS directly, but it is likely your going to find you have limited video format support.

    This is where a raspberry Pi or similar comes in handy as you can load Plex or Kodi or one of a hundred other thing onto it which will convert the video for you to whatever your projector supports.

    A Pi 4 has wifi support so it could connect to the NAS wirelessly and the Pi 4 has HDMI and an audio port for you to connect to your projectors.\nYou will likely need samba for file sharing.

    I have found on shopping sites that small PSUs are little cheaper than 500+ Watts PSU.

    \n

    So I want to buy the lowest one because I have no plans for adding external GPU.

    \n

    I would be using 2x8 GB RAMs and Micro ATX motherboard (something like entry level B450 or B550). And I would use only stock cooler and no overclocking.

    \n

    The official docs of this APU says:

    \n
    \n

    Default TDP: 65W

    \n

    AMD Configurable TDP (cTDP): 45-65W

    \n
    \n

    I am not sure if there's actually a relation between 65W and the Power Supply I need.

    \n

    Or if it means the minimum PSU you need for this APU is 65W - I am not really sure.

    \n

    I also found on a site which recommended minimum 300W power supply for this APU without any dedicated GPU. And the recommendation was a little more (350W) if you want to use some entry level GTX GPU like 1050ti.

    \n

    But they didn't give any reason for this. But this lead me to conclude that it can be used for less than 500W power supply easily.

    \n

    So, I would like to know what minimum range of power supply unit for this APU. So that it gives quite the same performance which a higher PSU like 500 or 600 Watts would give.

    Enough is enough. If you can get a quality 300W PSU, that will give you more reliability than a cheapo 600W one. Where I live, quality PSU's don't go as low as 300W, the lowest is 400W. Get them from a reputable brand (NOT aliexpress or Gigabyte, Seasonic or Corsair are better) and preferably with 80+ Gold rating.

    BTW the power supply never impacts performance, only reliability and stability.

    Given I don't know what to look for, this is my research.

    \n
    \n

    your specs of HDMI and 60 fps and at least 720p are pretty low... such that a 10 year old might laugh and say my phone does better...

    \n

    what used to be 30fps and 720p, the norm now is 60 fps and 1080p.

    \n

    my motorola phone for example:\nhttps://www.verizon.com/smartphones/motorola-edge-5g-uw/\nvideo : 4K UHD (30fps), FHD (60/30fps)

    \n

    FHD = full high definition @ 1920 x 1080p, which is now becoming the old standard.\nUHD = ultra high definition which is the now common 4k resolution at 3840 x 2160p.

    \n

    Both are 16:9

    \n

    off the shelf go-pro's and knockoffs are all 4k these days, typically at 30fps.

    \n

    but just google 4k 60fps camera or camcorder for starters

    \n

    if you buy a high end video camera you can almost always dial its settings down from 4k to 1920x1080 and 30fps.

    \n

    most everything is going to show up as still camera, but they all have video recording capability so look at the video recording specs. Find the one supporting the largest SDHC card you're willing to buy, 4k @ 60fps will eat up storage quick.

    I've been working with these a while. I picked up a pair of X540-T2 - they're 'server' cards, so run a little hot, though there's a version with a fan. The T suffix means native copper support so you don't need a SFP.

    \n

    They're PCIe 2.1 x8 for TWO ports, and you can run a single port at full speed (tested by speed test) on a x4 slot with no issue. The x550 is a newer version that'll work on x4, but I've not found them cheap on the secondary market. They're about 90usd + shipping on aliexpress, but prices vary wildly - as of 2023. they're down to as low as ~20 USD or less. They are EOL but the current intel drivers support them. They won't downgrade to 2.5 or 5 gbps, so you'll need a 10gig copper capable switch or connect them directly. On windows the drivers are excellent and easy to use, and as older cards they're well understood. They have a mild tendancy to overheat, so run it on a system that's capable of cooling it. While both these cards are "obsolete", they're common and supported with current drivers.

    \n

    I've not tried it yet, but most modern low cost 10Gbps cards are based off Aquantia chips - they'll work with the 'slower' multigigabit standards and are about the same price as my x540 for a single port. They do PCIe x4 and seem a better option in quite a few ways. I believe asus sells one, as well as various chinese vendors like comfast.

    Should I try bigger like 3.5" hard drives? Would they be more safe?

    \n", "Title": "Memory RAM for PC - is important the voltage value for performance and impact in the motherboard?", "Tags": "|motherboard|memory|performance|", "Answer": "

    The best recommendation based on how you asked would be...

    \n\n

    The 1.35v is within spec for DDR4 and is nothing to be worried about. The 1.2v is the original reference voltage for the DDR4 spec when it first came out however long ago. Nearly every motherboard supports 1.35v.

    \n

    Best thing to do is for the motherboard make/model you're thinking about, check their QVL (qualified vendor list) and RAM compatibility before you buy RAM. You are not required to buy any specific RAM they list, use it as a reference such that if they list a bunch of 1.35v dimms at the higher clock speeds then you can be sure that mobo supports that clock speed. But, for example, if that list only shows up to DDR4-3200 and doesn't list any DDR4-4xxx, then don't go buy a DDR4-4xxx dimm.

    \n

    The lower clock speed dimms all run at the reference 1.2v DDR4 voltage. All the performance ram simply runs at 1.35v in order to get that higher clock speed. There's very little to be gained or lost by trying to decide between the 1.2v or 1.35v other than theoretical power usage but that may even be a mute point since typically ram automatically downclocks itself to work with the ram speeds the motherboard is looking to use... which is to say even a DDR4-5133 may still work on a motherboard that doesn't advertise it supports it... but I'd only try that if I already had the ram in hand versus buying it and hoping it worked. A 1.35v dimm will not have any kind of negative impact.

    The Gen as in generation refers to PCIe 3.0 and PCIe 4.0.

    \n

    4.0 has double the performance of 3.0, you can look all that up on google. The key point is whether you're motherboard supports PCIe 4.0 or not, PCIe was released in 2017 but nothing pcie 4.0 came to market for a while. It's been a while since I looked into it, but that's what you want to look in to.

    The x4 reference is the pcie lanes that the m.2 ssd is using; there's x1, x4, x8, x16. graphics cards use either x8 or x16. The amount of pcie lanes that an ssd uses I believe is x4... they throw that x4 into the ssd marketing to wow buyers, because, x4 just sounds b@d@ass added on with all that other technical jibber jabber. I don't think m.2 ssd, because of the size of it can do more than x4 you would need more pins and a full size pcie slot that is now a few inches long as opposed to about 1 inch.

    I've heard a lot on YouTube reviews that 6500 XT is better than GTX 1650 but there's one bad thing about it. 6500 XT renders video at very slow speed especially in Premiere Pro (maybe rendering is done by CPU and not this GPU. I'm not sure how it works.)

But if your video edit software only supports CUDA and not OpenCL, the 1650 is faster. Since Premire Pro supports both, I would reccomend getting the 6500XT, but make sure the render device is your graphics card since CPU's also support OpenCL.

    I have started looking into eGPUs and their capabilities. My reason for using an eGPU is for coursework in CADD. I currently run a virtual machine to run the software for my classes (see list below). I have been able to run Revit 2022 successfully but I fear that as my classwork will start delving into more rendering my VM won't be able to handle the demand.

    The QVL shows DDR3 1600 up to DDR3 2600. If you buy DDR3 greater than 2600, they will typically down clock and still work to meet the motherboard which is limited to DDR3 2600 but you do take your chances in doing so. With DDR3 being obsolete kinda you may only find cheaper DDR3-3200 for example, which is ok, but ideally choose something comparable to the RAM QVL. You do not require the GSkill or Corsair make, or only those makes listed on the QVL, while they are probably the better/best out there the no-name brands on amazon or elsewhere will work. Just go by DDR3 between 1600 and 2600 and a kit of 4x8gb dimms. There is an SSD QVL from ASUS you can also reference as well, although any sata ssd on amazon will work. consult the documentation and email ASUS for confirmation before buying a pcie nvme type storage device to hold a bootable operating system.

    Price difference is not a problem to me. It's not very significant.

    \n

    I also checked official specifications especially about memory which shows the memory interface differences:

    \n

    \"enter

    \n

    4 GB variant:

    \n

    \"enter

    \n
    \n

    Why I feel 4 GB variant can not be a good choice:

    \n

    I read some comments on Reddit that this GPU is not powerful anyway. So it won't be able to use 4GB anyway.

    \n

    Some people say 128 bit is better than 64 bit as it will allow faster speed.

    \n

    Maybe 128 bit memory interface is only used because it has 4GB memory? It has nothing to do with a fact like 128 bit is better than 64 bit? I'm not sure. That is also what I'm curious about.

    \n

    Given all that, which one would give better performance on same PC for same games? And do 64 bit and 128 bit difference matter in this particular case?

    \n

    Why I feel 4 GB variant can not be a good choice...

    \n
    \n

    the 4gb variant is the better choice between those specific two, as benchmark scores (if u believe them) also point out. The redit rationale about not being able to use all 4gb anyway is ridiculous. If it uses 1mb of video ram or 1000, 128-bit will operate twice as fast as 64-bit, simple as that! Where the rubber meets the road is in the comparisons between clock speeds of everything, which i cannot find for 550. But like with all other graphics cards makes/models the variants are always faster... usually the result of minor overclock, and sometimes extra ram.

    \n

    The RX550 is better than 550; the 550 will not outperform the rx550.

    \n

    There are many better cards than RX550.

    \n

    Radeon RX6400 @ $160 second from top at best value chart: https://www.videocardbenchmark.net/gpu_value.html

    \n

    the biggest factor may be in 550 not supporting latest versions of openGL and DirectX where the RX550 will, so that reason alone will likely make rx550 better than 550. The "550" probably went obsolete a few months after release when AMD got the rx550 selling, now the "550" is just obsolete already built cards that haven't been recycled yet where sellers are just looking to offload them.

    \n

    what i could find: https://www.techpowerup.com/gpu-specs/radeon-550.c3407

    \n

    550 shows same clock speeds as RX, so no, no way it'll ever be better than rx550; all amd probably did was update the memory bus to 128-bit and double the vram circa 2017 to compete with market competition.

    \n

    https://www.techpowerup.com/gpu-specs/radeon-rx-550.c2947

    \n

    and given the fraud in the graphics market, hard to tell 550 from rx550 from 560 and 570; what you find as "rx550" advertised as 128-bit 4gb ddr5 you might get a 64-bit 2gb card so be careful with end of life stuff like that.

    I have HP EliteBook x360 1030 G7 Notebook 13" laptop. It's built-in monitor has Full HD resolution and 60Hz refreshing rate.

I'm working in hybrid mode - 2 days a week in the office (with some big monitor there) and 3 days at home, so I'm switching between monitors almost each day.

    \n", "Title": "Will my laptop work properly with high performance monitor?", "Tags": "|laptop|monitors|", "Answer": "

    According to HP's website, your laptop contains a HDMI 1.4b port and 2 Thunderbolt ports capable of DisplayPort 1.2. These will be the limiting factors as to which resolutions and refresh rates your laptop can run, assuming you purchase cables running at that standard or higher and the monitor supports at least that standard or higher.

    \n

    HDMI 1.4b specifications say that it can handle up to 3840\u00d72160 at 30 Hz, and 1920\u00d71080 at 120 Hz. However, HP's website says your laptop is capable of up to 4k (3840x2160) at up to 60 Hz using the HDMI port.

    \n

    DisplayPort 1.2 should be able to handle 1920x1080 at up to 240 Hz, 2560\u2009\u00d7\u20091440 at up to 165 Hz, and 3840\u2009\u00d7\u20092160 at up to 75 Hz. However, at this point there are no official guidelines restricting companies from calling their DisplayPort ports whatever version they want, so there is no way to know for sure.

    \n

    In conclusion, you should be able to run either of the monitors you linked at full resolution and refresh rate using Thunderbolt to DisplayPort or HDMI (assuming you get compatible cables).

    \n

    In my experience with a similar HP laptop, I could not get 4k at 60 Hz working on HDMI, but it worked with DisplayPort over Thunderbolt. 1440p at 75 Hz worked with DisplayPort as well, but I never tried HDMI.

    \n

    If you need to change refresh rates or resolutions for specific monitors, it should auto-detect and keep your settings every time you use that monitor as well.

    what Robert said in the comment... cell repeater... is close. Look for Cellular Booster. Loaded on amazon, minimum price is around $130 currently. You can spend $500 easily on a good one, and upward of $1000. There's plenty of online articles and reviews and you can buy direct from manufacturer if you prefer... weboost, wilsonamplifiers,

    \n

    The better ones in my opinion are those with the outdoor antenna being a yagi type of directional antenna; use "network cell info lite" on an android phone and it's map feature to identify which direction the cell tower is and then point the yagi antenna that direction (I know kinda catch 22 needing signal to know where the signal is coming from).

    \n

    The indoor antenna (i.e. repeater) comes in a few flavors and strengths... one room power, whole house power, small business office coverage, etc. That's where the price goes up.

    \n

    you said mobile internet. If by that you mean getting cell signal on the go... as you move around in your car, they have mobile cell boosters with an omni directional outdoor antenna (because as you move the location of the cell tower changes you wouldn't have a yagi on your car) and then the indoor repeater antenna is much lower power because all you need to cover is the inside of your car or rv.

    \n

    important : know the carrier and band your phone uses, and who you care about getting service for, not all boosters work on all service providers and bands. For example I am verizon and use band 13... in the specific home location where I have weak signal ... boosters that don't explicitly state covers band 13 will not work in my specific scenario. Plenty of times I've seen.... i've got full bars but he doesn't... elsewhere where there is a booster/repeater being used and it's because one person's phone is verizon and the other person is at&t, or sprint, or whoever else, on different bands that the booster does not work on. So be sure to look into those details regarding band and carriers supported by cell boosters, the cheaper ones will be limited in who they boost, the one's that boost everything are $1000+. Use app on your phone (android = network cell info lite) to identify the band of your cell, what band it is serving and if it is 4G, or 3G; 5G currently is iffy don't expect to simply buy a booster and get full bars of 5G.

    My notebook (Dell Precision 5520) has Thunderbolt 3.

    Thunderbolt 3 provide 40Gbps (double the speed of Thunderbolt 2).

    \n

    But there was a catch. My notebook (Dell Precision 5520) can only run 3 displays. So if I use 3 external displays with my docking station, my laptop display is getting turned off.

    \n

    My notebook (Dell Precision 5520) is not the only one suffering from it. It is a new trend, new laptops these days have kind of 2 video cards. In my case it is Nvidia Quadro M1200 with 4Gb of video memory and Intel HD Graphics 630 with shared memory. Nvidia Quadro M1200 - designed to have no video outputs, it works like a "slave". Intel HD Graphics 630 - is a "master" in this context. So the "master" sends all the heavy calculations to be processed by the "slave" and only displays what is returned by the "slave". Thus, even having 4GB of video memory and "Nvidia Quadro" on board, the overall configurations still limited to the number of screens that the "master" video card can provide.

    \n

    Lucky we have displaylink on the market, they make chipsets that work like external video cards.

    It will be safe to use a type-C to micro type-B adapter.

    The 100W power delivery that USB-C provides can only be used by another USB-C device. That's because there are extra pins that communicate the power requirements and allow both devices to agree on a power mode.

    \n

    If those pins aren't connected (like when converting to USB 2.0 or 3.0 Type A/B), then the USB-C port will deliver the standard 5V power over the power pins to remain backwards compatible. There will be no harm to the phone.

    I'm looking at two graphics card models from Asus:

    \n
      \n
    1. DUAL-RTX2060-O6G-EVO
    2. \n
    3. DUAL-RTX2060-6G-EVO
    4. \n
    \n

    As you can see, both are RTX 2060 graphics cards. I compared their official specifications and they have exactly same tech specs except following:

    \n

    O6G\n\"enter

    \n

    6G\n\"enter

    \n

    So, I believe the only difference in both is the clock speeds in Boost and Gaming modes. O6G seems better (if more == better).

    \n

    The price difference is not huge but O6G is little more expensive.

    \n

    Apart from that, my main doubts in choosing one of them are:

    \n
      \n
    1. I will use a stock ryzen coolor (and a low budget B550M motherboard) with my Ryzen 5 5600 CPU. So I feel if I buy O6G, it will give better performance while doing work/gaming but at the cost of more heat generation
    2. \n
    3. I personally feel like OC graphic cards generally generate more heat and performance boost is not that significant. So a default clock GPU would be better if heat is a factor.
    4. \n
    5. Even if I buy the O6G model, I will tend to use it a default base clock to ensure a longer life of the card and less heat. I would disable the OC feature. But I'm not sure if it is officially provided by a GPU brand in their OC GPUs or not. If there's a feature/option provided by GPU brand (Asus in this case) to disable OC mode, I would probably buy any of the models. For example, I would buy O6G if it were cheaper. It won't make a difference to me. I've read that Afterburner software allows you to change clocks and power but I don't want to use any third party software. I'm not comfortable with tweaking settings and I fear I'll mess up the hardware.
    6. \n
    7. If the difference is not just the clock speeds and minor gaming/working improvements as discussed above, e.g. some other useful feature/function/benefit which O6G has and 6G doesn't have, I don't want to be limited to them. I will probably go for O6G.
    8. \n
    \n

    I've also read here and there that factor OC cards can have little less life as compared to default ones.

    \n

    So given all my doubts, which would you recommend? Would you still recommend O6G?

    \n", "Title": "O6G vs 6G graphics card from same brand", "Tags": "|graphics-cards|pc|cooling|", "Answer": "

    The O6G is probably better binned silicon by Asus which is tested to be more stable at higher boost clocks. But looking at all your concerns it looks like the 6G is a better fit for your needs, since the difference might not be that great for the money and you want to keep it at stock speeds without tweaking. IMO just go for the 6G, at the very worst, if you wish, you could probably OC it to match the 06G if you ever get comfortable with Ocing. Thats why the 06G was created, for folks who dont want to OC their GPU's

    I've long been hunting in all the local stores and online but cannot find a single unit like this, which is baffling to me.

    \n

    I'm talking about some sort of small audio player which consists of only one or two speakers, a volume knob, a power button, a pause/resume button, a "next" and "previous" button, and a memory card slot.

    \n

    I can find ones which have a cassette player, radio, CD, etc., as well as a USB socket, but I don't want those for these reasons:

    \n
      \n
    1. I don't need any of those features, so it takes too much space and costs too much money.
    2. \n
    3. A USB socket is not the same as a memory card slot, even though they are basically the same technology, because an USB stick "sticks" (no pun intended) out from the unit in the front and thus both looks ugly and ruins the compactness.
    4. \n
    \n

    It should support MP3 and FLAC files. If there is only one "track" (file) on the memory card, it should loop it perpetually.

    \n

    My purpose of this would be to put on a 30-minute recording of the soundtrack of "Zora's Domain" from the 1998 video game Ocarina of Time to play constantly while I'm in the kitchen as a soothing background sound.

    \n

    I currently have a white noise machine in the kitchen, but sadly it only has a few baked-in sounds that loop and no slot for a memory card (or USB). It eventually gets on my nerves to hear the white noise and such sounds.

    \n

    Also, in Christmas time, I would replace the Zora's Domain file with some digitized classic Christmas music tracks from my childhood which can play instead.

    \n

    I'm not looking for anything that uses "Bluetooth" or whatever and requires some other device to be "streaming" data to it, or which requires "wifi"/Internet.

    \n

    Is this really such a niche concept that there is no such thing?

    \n", "Title": "Is there a minimal, cheap device which just plays sound files from a small memory card?", "Tags": "|audio|music|mp3-player|", "Answer": "

    You should search for portable bluetooth speakers.\nMost units will include a memory card slot and enable playback of files directly, which should do what you want.

    \n

    It's unlikely that you'll find a unit that ONLY includes a memory card slot and no bluetooth/radio/usb/etc. There just isn't enough demand to justify "simpler" devices and the extra cost associated with the features is likely minimal.

    \n

    By doing a quick search for "Bluetooth speaker with memory card slot" on Amazon, I found several speakers that would accomplish what you need for a fairly low cost (around $30USD). No doubt that other vendors or brick-and-mortar stores will also carry a selection.

    \n

    Sadly, if you absolutely do not want other features, you'll probably have to learn how to make it yourself or pay someone to do so.

    I have a problem with disconnecting DisplayPort cables. Almost all other connection cables are normal, but with dp it is another story. Some dp cables has latches - a locking mechanism. It does not allow you to just pull the cable to unconnect it. You need to press the mechanical button that will release latches.

    \n

    \"enter

    \n

    This was probably designed for "reliability", but that really brings nothing more than problems! This button is hard to press sometimes, and is inconvenient even when you can do it. And there are situations when you just physically cannot press it, leaving you in locked down position.

    \n

    In my case, I cannot disconnect dp cable before I remove the DVI cable, see picture:

    I disassembled my cable, and unfortunately, I doubt I could successfully remove that mechanism and then assemble the cable again.

    I know there are cables without latches and I can purchase such to replace mine. But still there are situations when you cannot just replace cable. In my case, the DisplayPort to hdmi adapter also has such latches, and I suffer from this same problem.

    \n

    So the question is: does such adapter exist that can take a male displayport connector with latches, and output the male displayport but without latches? In other words, can I remove latches by placing adapter and not by modifying the cable itself?

    You can "disable" latches by using this adapter. And you do not need to break your existing cables.

    (Hey, so i was searching for a (relatively) cheap pair of in ear wireless headphones with decent audio quality, ac doesn\u2019t matter to me.

    Ok, i somehow found it now:

    \n

    fn4 are pretty much just true wireless headphones without any extras (although some, like me, actually don't like active noise cancelling anyways because many implementations create pressure and hurt your ear even more over time) but still cost more than some others at this point in time.

    \n

    fn5u has active nc and the uv anti bacteria cleaning

    \n

    fn6 is the same but qi charging box instead of active noise cancelling

    \n

    fn7 has all of the above

    \n

    As it seems there's none which's audio features you can't control via the extra app.

    \n

    The dfp lineup seems to have more microphones and LG claims them to have better audio. Their shape also seems slightly different to me, although which design is better may be subjective. Furthermore the feature to use one bud as microphone for whispering on phone calls seems exclusive to the dfp line-up and ear caps from some medical material. They still have the uv cleaning btw.

    \n

    Besides that:

    \n

    dfp3 (not even meridian sound if that really makes any difference)

    \n

    dfp5 (ac)

    \n

    dfp8 (ac and qi loading case)

    \n

    dfp9 (no qi but \u201eplug and wireless\u201c)

    I hope this is a simple helpful list for anyone who wants to buy a pair.

    Charging is quite simple. It depends on the maximum current in Amperes(Amps) that the cable can carry. The maximum Amps that any USB charge cable needs to carry is 5 Amps (5A). As long as it can carry truly carry this much current without overheating, and the wires are wired correctly on to the connectors you should be fine in any use scenario. The voltages don't matter and the wattages don't matter with regards to the charging cable. The only other thing to note with regards to unprotected cables without the emarker chips, resistors etc. are that as long as you are using the correct charger (for that particular device - does not have to be the original one, just one that is truly compatible with it-even third-party ones) it should work out fine.

    As you know RTX 2060 was relaunched with 12GB VRAM and other changes like more cuda cores but less bandwidth.

    \n

    I checked performance of both on various benchmarking websites and they are more or less same for 1080p gaming. I'm interested in buying the 12GB version for following two personal conclusions:

    \n
      \n
    1. 12GB is obviously a lot more than 6GB. Even if this card is basically similar as old one in terms of other specifications, it's still better than 6GB memory, by some percentage. For example, it might not be powerful enough for 12GB, but maybe its performance won't degrade upto 7GB or even 8GB.

      \n
    2. \n
    3. It might perform better in non gaming tasks like video editing and basic 3D modelling, irrespective of similar specifications apart from VRAM.

      \n
    4. \n
    \n
    \n

    Now the other thing is, when it was relaunched, it was criticized by almost everyone. Mainly for its price. And many people say it isn't even powerful enough for 12GB so it's a scam. I'm not sure how true is it especially the "powerful enough" thing.

    \n

    I really don't think pricing is factor now because the pricing has become much better today, the only concern remains about the performance. Not sure if I am going to see any benefit of 12GB at present or near future.

    \n

    I can't afford a display greater than 1080p in near future. And I have no plans either. But I think that maybe in next 2-3 years games might need a little more than 6GB for 1080p gaming. So I'm not sure if I should invest in 12GB or 6GB. The price different isn't that big.

    \n

    Like I said, right now their performance benchmarks are more or less same. But if this 12GB makes the card a little more better as compared to 6GB variant in near future, especially in gaming, I would prefer the 12GB one.

    \n

    I went for Processor and Mobo combo which isn't 100% upgrade friendly but allows me to save about $200 and I am not planning to keep upgrading this build to newest and latest. I also picked open box power supply in favor of better quality and keeping my final price low. Video card is not the top off line but, it has just enough cores for my light video editing.

    \n

    This is about the best SATA SSD series that I know of, they are not very expensive and are availible from 1/4 TB to 4TB. With your budget, 500GB is probably the best option.

    \n

    I'm getting a little off-topic here, but if you want to transfer your files, I reccommend booting from an Ubuntu live ISO (on a USB stick or DVD) and using dd to transfer your files, and Disks to resize the partition so your OS (Linux, Hackintosh or Windows) sees the extra free space. (and for the diamond mods, I include this so there is not an off-topic question about transferring your OS that I have to close)

    \n

    About the durability, the larger the SSD, generally it can also be used longer, because you can write more to it since you have more NAND cells you can write to. Although each NAND cell can only be written to about 360 times, with a larger SSD you have more of them so they wear down less quickly (or you write more to your SSD, but don't do that too much)

    Because Raspberry Pi's are hard to get nowadays, I'm looking for an alternative single board computer.

    I've seen several sites that list all kinds of alternatives, but those websites don't talk about the thing that is most important for me: software compatibility.

    RockPi are widely in stock, better performing single board computers. They do generally support most RPi Hats, with exceptions suck as PoE Hats.

    They do cost more than RPi 4, but have generally better and faster hardware.

    The RockPi has an RK3399 SoC arm64 CPU, roughly 50% faster to twice as fast as RPi4/3 and is binary compatible for applications. RockPi will not run Rasperberry Pi OS, but have many more options.

    The concern of my question is about router security via updates.

    \n

    I used to have various Modem/Routers (eg. Belkin, TpLink, etc.) over the years to connect to my ISPs. All followed the same pattern: Manufacturer supported them well at the beginning, the devices were receiving regular updates, then some years later they were reaching end-of-life and there were no more updates.

    \n

    Also, I want to change the way things are connected at home.
    \nInstead of having every device connected directly to the Modem/Router, I want to have everything connected to a Router (To-be-purchased), and then have that Router bridged to the Modem provided by the ISP.

    \n

    So the question is:
    \nCould you please suggest any Router devices which receive regular long-term updates for many years? The longer the better.

    \n

    (FYI I have looked into Mikrotik, OpenWrt but I don't know for how long they provide updates. Also, I wouldn't mind purchasing a business-oriented device if it suits my needs)

    \n", "Title": "Looking for Routers with long-term updates", "Tags": "|networking|router|security|", "Answer": "

    Its a bit of a "frame challenge" but if you want longevity over power efficiency, don't buy a consumer router. Get an X86 box with at least two ports - I think the N5150s are the current darling and give you multigig ports, but I've been running this since 2018 on a customised ubuntu linux build with multiple ethernet ports.

    \n

    Since its a generic machine, you basically get updates forever (or as long as the project you're using for the router backend is supported). They don't do wifi as well as as a dedicated AP or router but that's heavily on the hardware end.

    I don't think you have to use splitters. You can use a Mini DP to DP adapter to connect one monitor, and connect the other one over HDMI. On the one connected over DP, you should be able to get 144hz, the refresh rate of external monitors is not bound to the refresh rate of your laptop monitor. On the one connected over HDMI, you may only be able to do 60hz because of the bandwidth limitations of HDMI 1.4.

    having mentioned RTX, as in Nvidia, assuming it's CUDA code then yes there is the programming capability to choose which physical GPU among many that are present in a single system.

    Regarding cost and multiple GPGPU's or GPU's (graphics cards) the cost of however many of those is the baseline.... to fit many into one server or workstation I believe will be more expensive than buying a $100 motherboard off newegg having one PCIe 4.0 x16 slot to accomodate just one graphics card. To fit two RTX3080 size graphics card into one PC type workstation you are generally looking at eATX size motherboards, a larger case, power supply and all associated stuff, such a mobo will run $500+ I believe.

    In some sites RAM is presented to upgrade which is barely available, so I like to buy RAM from some local dealer. My questions are:

    \n
      \n
    1. If I buy DDR4 16 GB RAM with a clock speed of e.g. 2400 or 2667 MHz, will it decrease the speed of the already placed RAM (1200 MHz)?
    2. \n
    3. Would I benefit if I buy two 2400/2667 MHz RAMs? (as maybe 1200 MHz is the maximum that is used by this 'old' laptop? (is there a way to know the best speed to use for this laptop? or is faster 'always' better?)
    4. \n
    5. If the latency of the new RAM would be e.g. 19, would then the 'overall' latency be 19 ? or worse than 17 or 19 ?
    6. \n
    7. If I buy one new 16 GB RAM and find out my system is much faster, if I would buy another same type of the new 16 GB RAM, is that equally good as buying a 'set of 2 RAM modules' ? Or can I assume two equally RAM modules would behave like a set?
    8. \n
    \n

    The RAM I have in mind is a Crucial CT16G4SFD824A (16 GB DDR 4 SODIMM 2400 MHz, CAS latency 17, voltage: 1.2V, ECC Type: Non-ECC\nor:\nCorsair Vengeance CMSO16GX4M1A2133C15 (16 GB, DDR4, 2133 MHz, CAS LAtency 15, 1.2V, Non-ECC)

    \n

    There are more types, but just some to show as example.

    \n", "Title": "RAM effects for upgrade", "Tags": "|laptop|memory|upgrade|", "Answer": "

    So the first effect is the RAM would run at double the speed. This will give you a performance boost of 0 to 50% (depending on the workload). Also your RAM capacity doubles so if you are now running low on RAM, you could be tripling your performance (if I'm being optimistic).

    \n

    Now let's look at your concerns

    \n
      \n
    1. The BIOS will choose RAM settings that are based off of the JEDEC settings and will in theory choose the fastest one that is on all modules. If you buy the Crucial stick, this will probably mean both sticks will run at 2400Mhz.

      \n
    2. \n
    3. See 1. Since it will take the fastest one compatible with both modules, it's probably better to get the same speed for there to be a bigger chance of it picking the wanted speed.

      \n
    4. \n
    5. The BIOS may adjust the speed to fit the slowest stick. This means if you mix CL17 and CL19 RAM it would probably run at CL19.

      \n
    6. \n
    7. Please don't do that. Your laptop probably only has 2 SODIMM slots and getting 3 sticks means you have to remove one and that won't give much of a performance boost. If you don't have one, spend that $60 on an SSD, which will give you a mayor improvement in OS/app loading time.

      \n
    8. \n
    \n

    From the example sticks you have shown me, the Crucial RAM fits your current RAM the best, so that will be your best bet. It's also $6 cheaper where I live.

    About the drives themselves: The WD drive is definitely not of the same type as the Seagate one. I don't dare open up the Seagate case since it doesn't look like it was meant to be opened easily.

    Thus, we can connect a thunderbolt laptop to a HDMI monitor and USB keyboard.

    On this way, a normal and such an "inverse thunderbolt adapter" could work like a remote console for old laptops.

    \n

    Does such a thing exist? Webshops and search engines show up always only the "forward" variant, unfortunately.

    The adapter you want does not exist.

    \n

    Thunderbolt is not bidirectional, there is a host side and a client side in its design.\nIn the normal "forward" adapters the host is the computer, and the computer has a chipset inside that essentially converts the Thunderbolt device into a PCI express device. It is closely integrated with the CPU or southbridge on the motherboard. Thunderbolt cannot even be added to PCs that don't have it (at the time of answering, USB 4.0 might change that).

    \n

    In that "reverse" adapter you proposed, the adapter would have to be the thunderbolt host because the laptop is not. That would require a rather high performance embedded CPU and OS to allow the thunderbolt end to function at all. This is cost prohibiting for a simple video adapter and I expect that is the reason why nobody has made one as a product you can buy.

    I work for a software company. When we sign new clients, the old software supplier makes a 'dump' of their database that we can then import. However, 99 out of 100 times we manually have to do a lot of things with these dumps to make them compatible with our software.

    Since these dumps can be pretty large (the sheet itself can be up to 500mb - 1gb) and contain 100's of thousands or millions of records), we need a really good PC that can handle this well.

    Opening a file that large is memory intensive and single core limited.

    Depending on active memory not used by cache, you will need at least that much ram. Reboot, then open a sample file and check your memory usage.

    I've recently (December 2022) learned that Apple no longer sells wired keyboards. My touch-typing has become extremely optimized for one of their USB keyboards and I'd like to find a suitable replacement. I use older Linux hardware, so anything with a battery or wireless-only features is not suitable, nor am I interested in increasing the number of adapters and dongles in my apartment to fit a new wireless keyboard to older hardware (these can be lost, and introduce points of failure).

    \n

    I do not know the official name/# of this model, but it can be described as: Aluminum body, USB-A cable, ANSI layout, shallow profile, slight angle, thin keys, numeric keypad, and essentially indestructible until you spill coffee on it.

    However, I can confirm, per @Tetsujin's answer, that the keyword "Apple A1243 US" does return some suppliers on eBay within the UK. I will be ordering one of those now.

    All my life I have bought all my gaming PCs with Intel CPUs.

    \n

    I always face a major issue, though: 2 to 3 years after buying a new PC, when I try to replace my 2 to 3 years old GPU with a brand new latest 2x to 3x more powerful GPU to match my gaming needs, my Intel CPU always becomes the bottleneck. I can\u2019t even just upgrade the CPU to latest generation to match the GPU because the motherboard won\u2019t allow it. As a result, just to use a new GPU, I have to buy a completely new PC!

    \n

    Are AMD motherboards better future-proofed so that after 3 to 4 years I could upgrade my CPU to match new GPU speed without buying a whole PC? Or is Intel also more future proof in recent products they release?

    \n

    why GPUs, generally are in another electrical board (video card) and are not like CPUs to be installed in the motherboard?

    \n", "Title": "why video cards/GPU are not like CPUs in terms of installation into a computer?", "Tags": "|graphics-cards|processor|", "Answer": "

    for the consumer market, as in the average person building a home pc from parts acquired from newegg or amazon, yes it seems like GPU's are not like CPU's in terms of their installation into a computer - with the GPU being on a separate piece of hardware (the graphics card) that plugs into the motherboard via PCIe slot (and use to be an advanced graphics port (AGP) back in the day).

    \n

    But a GPU is very much like a CPU, in terms of die form factor. And there are direct motherboard installations. The best example being the SXM2 form factor from Nvidia. You won't find this in the consumer market, this is in the enterprise / corporate realm where you are looking at a rack mount style server that costs upward of $50,000.

    \n

    Dell has a model C4140 for example that incorporates some number of SXM2 style Nvidia gpu's, V100 model and later. I'm sure there are similar offerings from other big manufacturers like HP, Supermicro, and so on.

    \n

    The gpu is however many mm in length and width, and dissipates N watts, and requires cooling, just like a cpu. Whether it's on a separate piece of hardware with it's own heat sink and fan, and is modular and plugs into the mainboard via pcie slot... or is incorporated onto the mainboard and has a heat sink on top of it just like the cpu does and uses case fans for cooling, is just form factor and is trivial.

    \n

    look at https://www.gigabyte.com/us/Enterprise/GPU-Server/G190-G30-rev-100

    \n

    we get gpu incorporated in to the cpu currently, with Intel's integrated graphics for example, so you can have a motherboard that has vga/dvi/hdmi/dp ports on it and you're not required to install a dedicated graphics card to get graphics. Will the consumer market ever see higher end gpu capability that sort of comes with on-motherboard gpu like the SXM form factor? with just 1 gpu there's no real good reason to go SXM style over modular pcie graphics card. SXM shines over pcie when you have multiple gpu's doing hard core gpu type of [cuda] processing, not just rendering graphics to a monitor to play a game. but who knows.

    The Intel HD 4400 was not a 'good' GPU when new & is now a 10-year-old design [no longer supported by Intel or Microsoft]. It's an on-chip device which was used on Intel CPUs for a couple of years between 2013 & 2015. To know more detail we'd need to know the exact CPU model number.

    There is a big difference in the amount of processing needed to power an "HD" display compared to a "4k".

    McMaster-Carr is another source. Note that the options are for NO and NC, normally open and normally closed. You'd want NO which means the switch is off unless activated. Steer away from M marked switches, which means Momentary, requiring that the switch be held in order for it to be on.

    The connector on the switch can be found locally, specifically at an auto parts supply store. Bring the new switch with you to ensure you get the right size connector and splice a pair on the existing pigtail. Polarity/position doesn't matter for this sort of installation.

    A switch should not fail in the manner shown. This implies that the current capacity was under-valued or there is a problem with the device causing more current to be drawn than expected.

    I can't guarantee 100% reliability but you could use https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/. I've looked up my drives and they're all correctly reported as CMR.

    \n

    A while back, when customers had bad experience with server drives that were SMR in disguise, WD ended up issuing a semi apology with an explanation of their Red drive strategy: https://blog.westerndigital.com/wd-red-nas-drives/

    \n

    For the past 5 years, I've been buying dozens of drives ranging from 8 to 20TB, all from their Elements brand (most of the time, it's a WD Purple inside the case) and so far, so good. When I found their blog post in 2020, I took it as a good rule of thumb that 8TB and above == CMR, no matter the "color". I've applied this logic since then and so far, not one SMR drive in the bunch. Quite a few Helium filled drives though.

    But if you're less confident with this logic, it doesn't hurt to double check with the first link.

    First check if your BIOS even lets you change the memory settings at all, many don't. If your motherboard BIOS allows you to tweak enough settings it is likely but NOT guaranteed you will find compatible settings.

    \n

    Yes, but with limitation.\nYou will have to use the worst timings for ALL memory chips.\nSo even though some memory supports 17-17-17 the worst times are 19-19-19 and you will have to use those for ALL memory.

    \n

    Across every category you will need to use the worst numbers, which in memory timing that usually means the largest number.

    One possible scanner is Canon CanoScan 9000F Mark II. It support 35mm, 120 format films out of the box. Up to A4 for reflective materials. I am afraid larger films must be scanned by hand and also by hand the person should apply corrections (for negatives). The scanner support up to 9600DPI (for films) and 4800 DPI for reflective materials. Can scan up to 12 frames from 35mm strips or 4 frames in single operation.

    I want to run something by people here to see if I'm on the right track or if I'm wasting my time.

    \n

    I found my old desktop computer from almost 15 years ago. After some initial research, I get the impression that I can make this computer a productive machine with just a few upgrades. I want to use this machine for Zoom conferences, and use it to do light video editing of my video meetings and online seminar/lectures that I attend.

    \n

    Here are the specifications that I was able to retrieve for my machine:

    \n\n

    Right now when I use the machine, the windows operating system might freeze randomly while I'm browsing the internet and watching youtube. I can reboot to get back to using the computer. But some time later, things can randomly freeze again. I tried replacing windows with Ubuntu 22.04 with a GUI, and similar freezing issue still occurred.

    \n

    I wonder if my freezing issue is the result of insufficient memory? 4GB does seem too little.

    \n

    Hence I was contemplating the following upgrades:

    \n\n

    Do you think these upgrades will allow me to use this computer for zoom conferences, editing online meetings/lectures that I've recorded, do some computer programming and database programming (sql server, mysql etc...) ?

    \n", "Title": "Will upgrading my 15 year old computer make it powerful enough for video editing?", "Tags": "|processor|motherboard|memory|", "Answer": "

    As to the self-suggested upgrades:

    \n

    You could try bumping the ram to 16gb, but DDR3 has a lot of compatibility issues across platforms, motherboards, speeds, etc. It's not like DDR4/5 where you get memory profiles that at least helps a lot.

    \n

    Going from a spinning drive to an SSD could be a massive boost to say the least.

    \n

    If you want to try it, go for it. I would set a strict budget for your upgrades to under $100USD, it really isn't worth spending any more than that in terms of trying. And even then, this is only if you're really budget constrained to begin with. You might be able to find a donor PC, or a much newer used option, depending on where you are at, on Facebook marketplace, ebay, craigslist or other options (buyer beware).

    \n

    Getting over 8gb ram is really essential for running anything with a modern browser. You did mention trying Ubuntu, which itself is rather bloated and 4gb was never going to cut it there. You could try a less resource intensive UI distro such as KUbuntu or Linux Mint (Mate). The browser will still be your biggest bottleneck.

    \n

    Unfortunately this may well still be insufficient for general use today. You might consider a 7000 series AMD laptop or mini pc that has RDNA3 level graphics, which are halfway decent for integrated and better than most lower cost GPUs from a few years ago or older.

    \n

    You're honestly looking at about 8 cpu generations, the first half at 5-10% improvements generationally, and the latter closer to 25%. That doesn't include increased cores and clocks. It's really a massive difference.

    I have an old ITX PC. The essentials of the spec are currently:

    \n\n

    The video card and PSU are recent upgrades. The rest is around 10 years old.

    \n

    Since replacing the PSU it has run reliably, however the fan is a bit louder than I would like. I believe the noise comes from the CPU fan which is the original. (I replaced the case fans with quiet models and it made no difference). That said, it isn't unbearable (maybe 25-30dB).

    \n

    I am looking to upgrade the motherboard, CPU and memory for much improved performance. I am considering:

    \n\n

    I would also upgrade the video card in the future, but not right now.

    \n

    So, this is pretty high end (which is what I want) without going crazy.

    \n

    What I am wondering is how the heat generated would compare with the current configuration. On paper, the new CPU has a lower power consumption than the old one (65w vs 84w) and probably better power management, so I am hoping the fan would be quieter. I am not sure how the motherboard will compare (I guess it is not a big factor) or the memory (possibly more, because there is more of it, but again, not a big factor).

    \n

    The PC will have various uses from running AI models to reading emails. So my ideal system would be able to handle the former case whilst being almost silent in the later case. I'd also want some headroom to slap a bigger video card in later.

    \n

    Any advice on what difference the proposed upgrades would make (if any) would be much appreciated.

    Upgrade Effectiveness

    \n

    Without more context usually I would assume that a GPU, then CPU upgrade would be the most effective at handling ML proccessing than anything else. While being a slightly older GPU by today's standards, I would not consider an RTX 2060 to be anything to sniff at. My estimation is that CPU/GPU upgrade effectiveness would largely depend on the AI/ML model's software implementation to exploit the hardware.

    \n

    GPU future proofing

    \n

    As far as future proofing upgrades of the GPU, you can check a resouce like pc part picker to perform what-if scenarios as it automatically filters by GPUs your motherboard are compatible with, if you decide your GPU isn't up to your standards. Perhaps you may want to consider the possibility of leaving spare slots for SLI, though I'm not familiar enough with the latest AI/ML standards to know how effective that is for your context.

    \n

    Regarding Memory

    \n

    In the case of your memory upgrade it's likely you'd already know if you were bumping up against a 8 gb limit assuming you monitor your system at all. If you're not coming close enough to the upper limit of that where your operating system is writing to the page file (on HDD), or using memory compression (increasing CPU load) you'll probably not see that much of a performance upgrade in that respect besides possibly some slight increase due to longer life of main memory caching.

    \n

    The largest performance gain you'd see from your memory is that fact that it has a significantly higher operating frequency than your former memory which will increase the over operating throughput of the system.

    \n

    Fan noise

    \n

    As far as your concerns with fan noise, higher end components tend to have a better chance of having fan speed control software through vendor applications which you could control directly to run at a slower quieter speed, at the cost of overall performance.

    \n

    It sounds like your PSU is the most noticable component in the system so without direct control over these fans, assuming there is some sort of software/bios avenue for it, would be to decrease the power consumption of the overall components, thus leading to less thermal dissipation. There are a couple ways to do this, which mostly involve utilizing overclocking tools to limit your maximum frequencies, or voltages. Note that thermal dissipation is a function that scales linearly with frequency but has a squared relationship with voltage.

    \n

    Your easiest bet outside of fan control software would be underclocking via software overclocking tools like Intel XTU or Asus's GPU overclocking software. If you're capable of dealing with overclocking from the BIOS more power to you. Otherwise, I'd be remiss to mention that messing with voltages is going to be more difficult than limiting maximum frequency.

    \n

    Lastly if the individual components are giving you trouble with sound you have the option to switching to water cooling (like an AIO (All-in-one) water cooling kit for you CPU for example) which will allow you to have minimal sound without sacrificing performance.

    How important is the number of PCIe lanes when choosing a graphics card for gaming? My computer is still PCIe 3 and I'm concerned, whether or not a PCIe 4 x 8 graphics card like the RX 6600 will cut it for me.

    Correct.

    \n
    \n

    A RX 6600 with its 8 lanes in my PCIe 3 system would have the equivalent of just 4 lanes throughput, right?

    \n
    \n

    Careful here. You still get 8 lanes of PCIe 3.0 if the card has 8 PCIe 4.0 lanes.
    \nThe RX6600 will run at 8x PCIe 3.0 in your board, and will get around ~7.8 GB/s.

    \n
    \n

    Should I rather invest in the RX 6700, which seems to be the cheapest PCIe 4 x 16 graphics card?

    \n
    \n

    That depends on the games you play.
    \nThe PCIe bandwidth is not directly scaling how much FPS a GPU can achieve. In some games you will find that running on 4x lanes has a negligible impact while other games will use as much bandwidth as they can get.

    \n

    This article from TechSpot shows some benchmarks of the same GPU used on different PCIe bus configurations for a variety of games. For most of the games they tested the performance drop going from 16x PCIe 4.0 to 8x PCIe 3.0 was around 5%. For Doom Eternal it was a significant 18% performance drop. So there isn't a general answer and the games you want to play should factor into your decision.

    \n

    My opinion is that for most games this drop in bandwidth is not going to be enough to cause buyer's remorse.

    \n

    If you're wondering about a game that wasn't benchmarked you can sort of judge whether it will lose FPS with less bandwidth based on some things about the way the game works and its engine.

    This has been an almost unattainable goal for a long time. Chaining Thunderbolt docks had downstream USB C ports which were capable of DP alt mode, however most of these were big desktop docks with separate heavy AC/DC bricks supplying more than 100W. A notable exception was the JEYI Thunderdock mini which used a USB PD power input. However, it didn't work correctly with a <100W adapter and so JEYI changed it to contain a small 100W GaN power supply. This and the StarTech DKM31C3HVCPD were the only solutions I am aware of. Both were very expensive, though. Nowadays with USB4 there are more such adapters built around the Intel JHL8140 USB4 endpoint chipset. Examples are the Sparkle Travel Dock and the j5create JCD401.

    \n

    Another solution is to combine two adapters:

    \n
      \n
    1. Convert the USB C signal to DisplayPort using an adapter which is capable of passing power. A very cheap such solution is https://www.amazon.com/dp/B0915ZR21Y this noname adapter is widely available. It has a USB C port on the side which is capable USB data only and USB 2.0 speeds at that but that's still useful for a keyboard and a mouse. This adapter is part of a family characterized by the PD input on the back, data only port on the side and something useful at the end: DP, mini DP, HDMI, Ethernet, VGA. I have been using it for some time and it does the job. No wonder, it's not a particularly complex device: it doesn't renegotiate PD and doesn't contain any data converters.
    2. \n
    3. reconstruct a DP signal with a bidirectional cable or appropriate "reverse" cable. Dan S. Charlton's blog contains many useful lists, in this case Bi-directional DisplayPort->USB-C, HDMI->USB-C, and HDMI->DP cables. One example would be the Amazon Basics Bi-Directional USB-C to DisplayPort Cable note this link goes to Amazon UK, Amazon US doesn't have it at this time. There are some which also injects power like the fairikabe DisplayPort to USB C same availability caveat. Dan's list has many, many more. This is typical: availability of these very special cables is spotty.
    4. \n
    \n

    The disadvantage of doing this is you need a PD source with two ports.

    \n

    However, these days there are adapters/cables which can take a USB C signal from the phone/laptop containing a DisplayPort signal, another from a PD source and has a third USB C port which contains the same DP signal and power from said source. Often only part of it: the adapter will send some to the host as well. Compared to the solution above, these solutions only use one power port from a PD source. Once again his blog contains a list of USB-C -> DP alt mode + power delivery \u201csplitter\u201d (or merger depending on your perspective) devices, this list is much, much shorter, at the time of this writing only contains four devices.

    Here are some minor details that I will be assuming when writing this answer:

    There are no good laptops with HDD booting anymore, so I will assume an SSD is also ok. Windows is currently also only Windows 11 on new laptops but you can still install Windows 10 on most of them.

    \n

    The one I would reccomend is the Framework 16 DIY. If you spec it out with 2x8GB RAM and a 1TB SSD, you would come out a little under $2000. For that kinda money you are getting an ultra repairable laptop (I have the Framework 13 and I have heared that the 16 is even better) with a Ryzen 7 7840HS and later the possibility for a GPU. You can connect up to 3 external displays if I'm correct (although you could technically have 6 HDMI ports but that's just stupid). The only downside is is that it has a backlit keyboard but I think you can turn it off. There is no option to buy a Windows 10 license (thanks Microsoft) but you can still install Windows 10 and then buy it later in the Microsoft store

That doesn't mean Quadro is useless, there are Ampere based Quadro cards (like the RTX A6000) and those are faster than the Geforce 4070 in some use cases (like the ones that require 40GB of RAM) so there is still a use case for Quadro cards, you are just comparing Turing to Ada, and Ada will AFAIK always win

    You could always use a "real" speaker system where the speakers have electrical terminals for speaker wire and have to be attached to an amp. Look for "bookshelf" speakers and a stereo amplifier. No reason you can't use this with a normal PC, and it might even sound better than most of those "all in one" desktop speaker systems.

    \n

    I have a set of these Micca COVO-S speakers attached to a SMSL SA-36A desktop amplifier. This uses speaker wire that I had to cut to the right length.

    You could also look at buying some "active" or "powered" studio monitors for PCs, which are like bookshelf speakers but they have all of the electronics inside the left or right speaker, then some speaker wire runs from the main unit to the other unit.

    So a bit over a year ago, I moved to a new laptop, and connected an external USB hard drive with the files from my old one. Since then, I used the external drive, labeled as Elements (E:), as a second drive, leaving it plugged in at (nearly) all times, working directly out of it, and mapping several taskbar items, shortcuts, program settings, etc. to directories in the external drive. I'd run many programs from it, leave programs stored in it open for long stretches of time, use performance-heavy programs from it, and work in very deep directories (For example: E:\\****\\****\\****\\****\\****\\****\\****\\****\\****\\****\\)

    \n

    For a while, this worked without issue, but eventually, the drive started automatically disconnecting during heavy use. After a while, it stopped doing it, but it came back again, and now it's just inevitable whenever I'm working off of the drive or using things on it for any moderate amount of time. Through some research, I've found out that the drive is very much meant for backups only, and not constant heavy usage, so I've been wanting to replace it with a different one more suited to the task.

    \n

    I'm planning to use Robocopy to move the files over from the original, since system images won't work because the drive disconnects partway through, and Robocopy should allow me to continue where I left off after it reconnects, and I'm planning to label the new drive as Elements (E:).

    \n

    For context, my current external drive is a WD Elements 2TB portable HDD, connected by USB. It's 3.5", 5400rpm, "Bus Powered," USB 2.0/3.0, and has a flash memory size of 2. My laptop is a ThinkPadT15p with 2 USB-A 3.2 Gen 1 ports, and is running on Windows 10. In spite of it being a laptop, I usually just leave it on my desk, only really moving it to one other place in the house when I have company or taking it with me when traveling.

    \n

    I've tried researching it myself, but I haven't really been able to find much information about what would fit my specific needs, and I'm not knowledgeable enough about how drives actually work to fully understand the differences between SSD and HDD, or to evaluate the specs of individual products. Again, I'd like it to effectively just be a second working drive, being available 100% or near 100% of the time, able to withstand heavy use, and at a similar speed to my current drive. It also needs to be at minimum 2TB, though it would be nice to upgrade to 3 or 4. That's just a nice-to-have though.

    \n

    In regards to budget, I'm willing to go up to around $300, maybe a bit past, but only if it's actually going to last at least a few years without having to be replaced.

    The price of SSDs has now dropped sufficiently that there is no longer any real need to have to consider HDs at all. They're bulky, delicate & easy to damage by dropping etc.

One of the major reason i am upgrading is because my current display is TN panel and hence having severe viewing angle issue, so this candidate has to be IPS to resolve the problem. The confusion here is that the website i mentioned is saying that the panel type as a-si TFT, while others are saying its IPS, even my local shop is sayig it is IPS.

    While there are e-readers with cellular data support and built-in web browsers that can access Wikipedia\u2014notably the Kindle Oasis ($250), which includes it for free\u2014using a web browser to read Wikipedia on an e-reader is frequently a subpar experience:

    \n\n

    As such, I'd recommend using an offline version of Wikipedia. While you'll have to connect to Wi-Fi if you want to download the absolute latest copy of a page, Wikipedia isn't the kind of site where you need the latest updates all the time. In particular, I'd recommend using Kiwix to download and browse Wikipedia offline. Kiwix uses the open-source ZIM format1, which supports hotlinks, images, formatting, and more; it's supported by the Wikimedia foundation; and it's available for a wide variety of platforms, including Android (via Google Play, F-Droid, or as an APK.) You can easily fit the entirety of English Wikipedia, with images, onto a 128 GB microSD card. Since all the BOOX models support microSD cards and run Andriod, you should have no problem loading Kiwix onto them. Plus, you can download other Kiwix libaries\u2014including StackExchange!

    \n

    Since the BOOX devices are intended as e-readers, they support plenty of e-book formats, and there's no restrictions on what stores or libraries you can use. Also, since they're running normal Android, you can also run whatever other apps you want, including your preferred PDF viewer/editor.

    The problem

    \n

    I have an array of Wi-Fi cameras at a location very distant from my wireless router. I have installed an extender as near to the cameras as possible, but the connection is very slow (I believe the signal travels over 100 ft). At times, I also have a hotspot device which is much nearer and much faster. Unfortunately, these cameras (Wyze) can only be configured to connect to one wireless network at a time and so they have no automatic switching capability like smartphones.

    Proposed solution

    \n

    I would like a device that is able to connect to the extender (always available) and the hotspot (when available), then repeat the signal (whichever is stronger; the hotspot) with a single SSID - this way it appears to the cameras as just one network. I am unsure if this would cause issues due to the inconsistent IP addresses.

    I have not managed to find such a device searching the web, the closest I can think to do is to make my own \u201ccustom\u201d router with e.g. a Raspberry Pi. Before I plunge into that, is there a pre-existing device like this?

    What makes me nervous about most of the "USB-PD breakout dongles" on Amazon, advertising both USB3 data transfer and 100W PD capability, is that I have a hunch that the PD port is designed to also be the port connected to the host device. I don't want to plug one of those into my workstation just for it to try to backfeed 100W into my mobo - I want it to feed 100 (or 15, who's counting) watts to the VR headset while still treating the headset as the client.

Hopefully you should be able to use at least 3-4 of the ports consistently at full power, even if you can't get all of them at 2.4A.

    I'm contemplating the use of U.3 drives in my next desktop PC build, although I have no direct experience with them. (The reason for considering them is largely because I want to be able to run at least some of them in RAID 1 and rotate the drives out periodically; having hot-swap capability would also be nice. Given that M.2 drives are generally right on the motherboard, swapping them out is much less convenient. My current build uses SATA drives but they are now unacceptably slow, relative to the NVMe competition.)

    The cabling also seems to be straightforward, though I confess I've slightly glossed over that part so far.

(Perhaps they are the only way to proceed in fact?!)\nI've yet to find a single U.3 PCIe card, which baffles me.

    \n

    I'll note that I've also found adapters which allow an M.2 drive to be converted to U.3 (or U.2) form factor. I would certainly consider using these as part of my setup (it seems to be slightly easier/cheaper to buy M.2 drives than U.3 in the <= 4 TB range), since with a multi-drive enclosure I'd still get the benefits of easily swapping out drives, and I'd just need as many adapters as M.2 drives to keep things really simple. (I don't yet know if this would permit hot-swapping.)

    I want to buy a GPU for amateurly using and fine-tuning LLMs or LMMs. I don't have enough money for buying RTX4090. I can buy RTX4060 TI 16GB VRAM or RTX4070 12GB VRAM. But i am so confused.

    When I tried to use LLMs on a 15 VRAM GPU azure cloud instance with vLLM docker images, So many LLM didn't work because VRAM not enough errors thrown from CUDA. I understood VRAM too important for using LLM with CUDA. RTX4060 slower but have more VRAM, RTX4070 faster but have less VRAM. Actually I don't need high speed because I don't have a real time process problem.

    \n

    Do you guess VRAM requirements will be reduced?

    \n
    \n

    no. problem sizes will only become larger in the future, requiring more VRAM on the GPU if a GPU is to be used. They may refine the code (llama2.cpp, llama.c) to be more memory efficient but i doubt that will compare to the inherent memory required based on model size and model size will always become larger.

    \n
    \n

    Do you guess VRAM will be increasable with RAM ([i am thinking] because Apple M3

    \n
    \n

    not sure what you are asking. yes VRAM on nvidia cards will increase in the future, just like anything else and has we have noticed over the years starting from 1,2,4 gb now up to around 32gb per pcie card such as a RTX 4000 series now has. Will it coincide with DRAM DIMMS that are modular and allows someone to plug in and upgrade I do not think so. Will VRAM get up to 64gb and 128gb like we see on consumer motherboards probably. Will VRAM approach the ~768gb RAM limit of the x86-64 cpu currently, I think it is possible for a niche market but not for the consumer market.

    \n
    \n

    What do you think about this problems

    \n
    \n

    Large Language Models (LLM) which I know little about, a quick internet search responds with Running large language models on a home PC? - You will need at least 350GB GPU memory on your entire cluster to serve the OPT-175B model.

    \n

    So it will depend on your LLM that you are playing with and what VRAM requirements you are dealing with. Playing with LLM's seems to be highly VRAM dependent, 350gb and mention of cluster gives the distinct impression that processing LLM's at home is not easily done and if so on very small models.

    \n

    you also mentioned docker, which is in regards to containerization, I would look into being sure that running in a cloud instance with containers that the clustered (more than one) VRAM of many GPGPU's is actually accessible, that may be a reason why you are seeing errors such as VRAM not enough. Make sure the amount of VRAM reported within the container (docker) is correct.

    \n
    \n

    Which GPU would you choose?

    \n
    \n

    of the three you listed the one with the most RAM, but if that's 16gb, or even 32gb, and LLM's generally need > 100gb or whatever then recognize that reality and understand the VRAM needs for whatever LLM's you are working with. Current market price of a used Nvidia V100 gpgu having 16gb can be found around $1000 USD, they do come as 32gb and new is up to around $5000 USD, and that is with them a few generations old now (turing, ampere, current is now hopper). You would need ~4 V100's to have > 100gb of [distributed] VRAM possible along with the associated hardware to connect those. Saying low-budget and LLM in the same sentence is not realistic (yet).

    I don\u2019t think USB-C charging can be universal across devices.

    \n

    This is not a charger or cable issue, but the manufacturers of basic consumer products do not set their devices with proper power negotiation circuits. Not much can be done in cases like that.

    \n

    I think the issue is the basic consumer products you are attempting to charge can only charge a 5 volts at 1 amp (5W) and cannot negotiate with a higher wattages wall charger.

    \n

    I say this without having solid specs on this, but I personally have converted to all USB-C items on my MacBook Air and have some items that can technically charge via USB-C but only do so when I connect them to a 5W USB-A charger. Items like a no-name \u201cAidisun\u201d bike flashlight and such.

    \n

    Look at what your KOOPAO (!?!) can charge at:

    \n

    USB-C PD (Power Delivery)

    \n\n

    USB-A QC 3.0 (Quick Charge 3.0)

    \n\n

    Nowhere does it say \u201c5V/1A\u201d but somehow that comes through with the USB-A connection?

    \n

    It baffles me, but my bet would be that all of the consumer products you mention:

    \n\n

    While they might have a USB-C connection, they can only work with USB-A connections because the manufacturers somehow did not set their devices with proper power negotiation circuits? They are effectively \u201cdumb\u201d USB devices that can only take what they are given but only if not above a certain (5 volts at 1 amp) wattage?

    \n

    I wouldn\u2019t waste time with new cables or even a new charger. Sorry to say, I don\u2019t believe the promise of USB-C charging across devices exists. Especially when makers of USB-C chargers and devices that claim to be cable of USB-C charging are so opaque about power requirements.

    \n
    \n

    FWIW, I just tried this out but if I connect a USB-A (Male) to USB-C (Male) to a USB-A (Female) to USB-C (Male) adapter I can successfully charge by crappy \u201cAidisun\u201d bike flashlight. According to my USB-C power meter, power is sent at 2.5W (5V/0.5A) which is pretty low.

    \n

    So I wonder if this the case where some consumer devices that have USB-C power adapters charge at 2.5W (5V/0.5A) but somehow can\u2019t negotiate with higher wattage AC adapters? Like if it is less than 5W (5V/1A) on pure USB-C to USB-C it doesn\u2019t know what to do?

    \n

    My guess is your USB-C to USB-C charging problems won\u2019t go away with a new AC adapter because the problem is ultimately with the consumer devices themselves.

    I'm inspecting NVIDIA GeForce RTX 3050. According to the NVIDIA official web, this card has 8GB memory. However, some laptops that state have this card, also say it has 4 GB. For instance, HP Victus 15. I have inspected some of those NVIDIA itself advertises (see this list), and the same happens.

    \n

    So does the RTX3050 have 4GB or 8 GB? If the mentioned card has 2 versions, is there any laptop finder that allows to specify how many graphic card's GB I want?

    \n", "Title": "Difference, in graphic cards memory, between NIVIDA official page and laptop specifications", "Tags": "|laptop|graphics-cards|memory|", "Answer": "

    The RTX 3050 mobile has either 4 GB or 6 GB of VRAM depending on your variant. The desktop version has 8 GB of VRAM. The 4 GB variant of the RTX 3050 mobile is also substantially slower.

    \n

    It's fair to say Nvidia's graphics card marketing names suck. To make a long story short, laptop graphics cards and desktop graphics cards generally aren't the same\u2014i.e. an RTX 3080 (desktop) is not the same chip as a RTX 3080 (laptop), and won't perform the same. Even if they were the same chip, modern GPUs are typically power and thermal limited; thus, in a laptop, any GPU can only perform as well as that laptop's cooling allows it. The TL;DR of this is that the only reliable benchmark for laptop GPU performance is... a benchmark of that specific laptop with that specific GPU. Which sucks, and is crazy confusing for consumers, but that's where we've ended up.

    \n

    That said, we can at least get a vague benchmark by comparing what hardware is in each laptop; generally, the easiest way to do this is by looking at GPU chip code names, such as this Wikipedia table for the GeForce 30 series.

    \n

    As you can see, the GeForce RTX 3050 Laptop always uses a GA107 chip (the same as some, but not all desktop RTX 3050s, but that's another can of worms.) However, where the desktop card comes with 8 GB of VRAM, the mobile version can come with either 4 GB of 6 GB of VRAM. Even more confusingly, the 4 GB version of the card is also a slower version of the GA107 chip, with fewer CUDA cores and stream processors. Eesh.

    \n

    Anyways, all this to say: despite having the same name, they're not the same really. It's marketing. The best we can do is provide you with a more specific laptop recommendation, given your budget and your needs. If you can edit your post with this information, we can help you better.

    The specific model of the A6000 that you linked says it is 10.5" long. If you're shopping for a different manufacturer/model of A6000 just make note of the length from that manufacturer's specifications webpage.
    \nYour case is the Meshify 2 XL which fits GPUs up to 13.3" (340mm) so there is no concern here about whether the A6000 will fit. FYI this case can fit even longer GPUs if you remove the metal structure for the hard drives, then it can fit practically any GPU ever.

    \n
    \n

    How do I determine if my current motherboard is compatible with the NVIDIA RTX A6000?

    \n
    \n

    The RTX A6000 requires a PCIe 16x slot, ideally that should be PCIe 4.0 but the GPU is backwards compatible. The physical dimensions of PCIe has never changed, and they almost always have forwards & backwards compatibility to allow old motherboards to use new GPUs, or old GPUs to work in new motherboards.
    \nYour motherboard is new enough to have PCIe 4.0 so there is no concern about losing performance anyway. The A6000 will fit and it will be compatible with the motherboard.

    \n
    \n

    How do I determine if my current CPU is compatible with my the NVIDIA RTX A6000?

    \n
    \n

    There isn't really a case where a specific CPU and GPU would be incompatible unelss it's something unusual like vendor-locked hardware for servers, or an engineering sample that's missing entire features. In general you can trust that any retail consumer CPU will support any GPU, there are standards to ensure this stuff "just works".

    The specs page for the A6000 (again, make note of the specs for whatever model you actually buy) says it can draw up to 300W of power.
    \nYour CPU and the other components in the system can probably draw near 200W, so the total power required for everything to run at peak load would be somewhere around 500 to 600 Watts.
    \nYour power supply is already a whopping 1600W which is enough to be using multiple A6000 GPUs if you wanted.

    I recently bought a secondhand Lenovo ThinkServer TS460, intending to run a home media server on it using UnraidOS. Here's Lenovo's Product Guide. The specific machine that I bought came with a RAID Controller (It appears to be the ThinkServer RAID 520i PCIe Adapter) connected to a board via MiniSAS that connects to all four available disk bays via SATA, and powers the four disks via this 8-pin connector (the port it connected to is labelled BP8_PWR_CON1).

    UnraidOS specifically states in their docs that it doesn't really support the use of hardware-based RAID controllers, but I figured that's ok - I'll just pull out the RAID controller and the board that connects to it via MiniSAS and connect my disks to the four available SATA ports on the motherboard.\nHowever I can't find a port to power the SATA connections. The product guide says that up to four disks are supported via the on-motherboard SATA ports, so it seems that what I want to do is in-spec.

And, for the price, it's pretty good value for the latest Dell has to offer... except, that as far as I can tell, it's not available in the UK yet. I'd expect it to come soon, but I don't have a definitive timeline.

    Asus ROG Zephyrus G16 (2024) GU605 - ???

    \n

    \"enter

    \n\n

    Asus's refresh of their popular G16 is looking pretty good. While it strangely lacks Wi-Fi 7, it's a minor oversight in an otherwise compelling device. I personally find the refreshed look to be quite aesthetically pleasing, especially in white. However, the OLED panel here is the real star of the show, and it's got good reviews so far. The big sticking point is the price. The device isn't actually out yet, so we have no idea how much it'll cost... and I wouldn't be surprised if it's out of budget, unfortunately.

    \n

    There's very little info available on this laptop (Lenovo doesn't even have a page up yet for it, only the Pro 7i Gen 9), but given the lack of an OLED screen, I struggle to see it being more compelling than the Zephyrus G16 unless you care deeply about Lenovo's keyboards or it's priced very competitively. In any case, it's not out yet.

    It's a great laptop, but for whatever reason, it seems to be weirdly expensive in the UK; an identically spec'd version of this laptop was $2179 (about \u00a31700) in the US before CES 2024, yet it's somehow more expensive now. Don't ask me how. If it happens to come up on a steep sale, I'd recommend it, but otherwise you'd probably be better off waiting on the new G16.

    Why do mechanical keyboards have 2x USB plugs? Ordinary keyboards only have one.

    For example Logitech G G815 has 2x USB plugs, also the whole previous models. Why is that? I have tried it and it is enough to plug in one plug.

    As mentioned on their site, one is a passthrough port. So, you can plug something close by instead of at the PC. And it not true that mechanical keyboards have 2X USB ports.

    I have an ancient laptop that officially maxes out at 384MiB; that's 128MiB soldered on the mobo, and a 256MiB SO-DIMM. I've swapped the CPU from a 1.5GHz Intel Celeron, with a 2.4GHz Pentium 4 (it boots!) and I believe that by replacing the CPU, the machine might allow more RAM, and I'm also hoping that it might allow for faster RAM?

    \n

    NOTE: The Pentium 4 did previously run at 2.4GHz (in an Intel desktop MOBO), and lshw shows it as product: Intel(R) Pentium(R) 4 CPU 2.40GHz, however it appears to be running at 1.8GHz... which is probably a good thing both in terms of power and thermals. It appears to be running fine (on mains power anyway) and is stable.

    \n

    Obviously, it's horrendously slow and the P4 probably won't help much. But if I could install 1GiB RAM, then it might be vaguely usable.

    \n

    Attached are photos of the original 1.5GHz Celeron, the replacement 2.4GHz Pentium 4 (I can't read the label but lshw says it's version: 15.2.7), and the existing 256MiB SO-DIMM.\nYes, the P4 has a heat-spreader on it which makes fitting the heatsink + fan... somewhat challenging... but that's fine!

    It would help if you specified exactly what model of laptop that you have, but with what i'm assuming to be your model is a 2002 Dell Inspiron laptop 2600/2650 which in this case the max amount of memory it can handle is 512mb and if there is only one slot then 384mb will probably be the limit unless you can try and use a 512mb stick and see what happens but to be honest I don't see it being worth the headache. It's a 20 year old laptop you can only expect it to be anything but fast, you could use it as a retro gaming machine or even run MS-DOS and learn some legacy stuff if that interests you at all.

    \n

    TLDR: No you can't upgrade to 1gb of ram due to the limitations of the hardware.

    Buy a used Q570/Z590 board

    \n

    Q470, Z490, W480, Q570, Z590, and W580 all support a a 2x8 configuration for CPU PCI-e lanes. However, I believe only Q570, Z590, and W580 are guaranteed to support a 2x8 CPU + 1x4 chipset configuration for PCI-e lanes, though some Z490 boards such as the Maximus XII Hero do support it. These boards should support your current hardware without the need for bifurcation.

    \n

    I believe any board on this list should work for you; currently, the cheapest board available new is the MSI MAG Z590 TORPEDO at $238.98. That's pretty pricy for an older board; given that this generation hasn't been current for a little while, I think you'll be better off with a used board.

    A Lenovo P16 laptop with a NVIDIA RTX 4000 can use up to 230 W power. The proprietary barrel power supply can provide it, but a standard USB-C docking station only provides about half of that.

    \n

    If I intend to use the GPU at full power, do I need to buy a docking station that provides 230W+ USB-C? Does such a thing exist? Or do I need to keep the barrel charger in also?

    \n

    Is it possible to not use the barrel charger, and for the laptop to draw the extra power from the battery, which will charge slowly from the docking station (of course, this will only work if I use the GPU for only short periods of time).

    \n", "Title": "How to run a 230W laptop + GPU from a USB-C docking station?", "Tags": "|graphics-cards|power-supply|usb-c|power|docking-stations|", "Answer": "

    You'll need to use a barrel charger or allow the battery to drain down

    \n

    The Lenovo P16 Gen 2 with the RTX 4000 supports USB PD 3.0, which maxes out at 100W (20V/5.0A). While there are USB-C chargers that can supply up to 240W (48V/5.0A), these chargers are using the newer USB PD 3.1 spec, and the Lenovo P16 Gen 2 won't be able to draw the full 240W even if you get one of these chargers.

    \n

    As such, you'll need to either use the slim-tip charger, or to rely on the battery when at peak load. For day-to-day use, you probably won't be drawing 230W continuously, so the latter is probably fine; however, you'll definitely want to make sure you have the slim-tip charger on-hand for when you need it.

    \n

    Aside: there are adapters that will let you use a USB-C charger with a slim-tip computer; however, they appear to max out at 100W currently. While higher-wattage versions may come later on, I wouldn't necessarily count on it.
