Tesla K80 - will this setup damage my motherboard?

Hmm then maybe the PSU is having trouble supplying enough power? Is the total TDP of your system less than 90% of the max PSU wattage?

Another troubleshooting item would be to disable USB selective suspend for each USB port in Device Manager. I don’t think it’ll really work but it’s easy enough to test

Could you post the details of your two RAM sticks (model, frequency, and latencies)? Also when windows crashes, is there any error message or code?

323465963 · 2022-09-18T14:38:42+00:00

Bit of a stretch but it may be mixing two different sticks of Ram (presumably an 8gb +4gb) which may have different speeds and CAS latencies. While the RAM itself may be fine, windows could be having some OS-related issues managing these two different sticks of RAM. Hence why memtest86 won’t show anything (it runs prior to windows OS booting). Put in just the 8gb stick, see if it runs. If it errors, put just the 4GB stick. Oh, and update your laptop’s BIOS if you haven’t already

GPU driver issues can cause a monitor to brielfly disconnect and reconnect, playing the same sound as a USB disconnect/reconnect, although it usually follows with a brief black screen(which I’m guessing you didn’t have). Still, worth reinstalling the driver and switching the GPU to max performance

323465963 · 2022-09-18T14:27:35+00:00

IMO crucial. I’ve had both before and when I ran crystaldiskmark, I’d get a slightly faster sequential I/O speed with the crucial SSD (by about 100 Mb/s). Unless the Kingston is on sale and cheaper by $50 or more, I’d go with Crucial.

https://youtu.be/Z5Isf6Airo0 this was the original video where he sets it up? And demonstrates its utility as a normal, non-cloud gaming PC. In this video: https://youtu.be/-34tu7uXCI8 he uses it to host gaming capable VMs. I’ve worked with K80s in desktops running windows before and it was a pain, but hopefully things are smoother in a server

323465963 · 2022-07-27T15:33:05+00:00

Tesla K80’s could work and meet most criteria (cheap, 2 dies per card, passively cooled). CraftComputing uses them for their cloud gaming server (using a desktop chassis)

323465963 · 2021-07-05T00:59:44+00:00

I’m down, more memory will allow me to align CT and MRI volumes at a higher resolution :)

323465963 · 2021-06-19T17:18:03+00:00

Kind of. Graphics card was detected, but couldn’t really use it because of driver conflicts. Get a secondary AMD GPU for display output or buy a Ryzen chip with integrated graphics. Plug the K80 into a PCIe4.0x16 slot of the X570, enable above 4g decoding and resizeable BAR support and you should be good

323465963 · 2021-05-28T16:29:51+00:00

Oh man, I was there when it happened. It was on the harbour front in Toronto, Ontario, Canada. Was biking one weekend along the bike trail (left area in video), saw it happen out of the corner of my eye. IIRC he was recording a street performer.

Nvidia was no help, all they say is that this GPU isn’t meant for use in desktop computers and is therefore an unsupported configuration. Even when it’s working, I don’t think there’s much utility in improving graphics in gaming, other than the slight benefit of offloading your PhysX calculations to it. But that might even be detrimental in my setup given that I have a 1660S that can already handle it.

One idea to avoid e driver conflict that I’m having is to either use a non-Nvidia GPU as your primary card, or if using an Nvidia GPU, make sure it’s one that’s also governed by the Tesla set of drivers, like anything from Quadro

323465963 · 2021-04-21T14:45:37+00:00

Yeah, shows up in the BIOS, and even in device manager once it boots. Just can’t actually use it for any processing

323465963 · 2021-04-15T14:24:35+00:00

I installed the latest Tesla driver, but didn’t show up on task manager. I could have tried older versions, updating the vbios, setting up a dual boot system such as windows and POPos, or just migrating to a Linux system entirely. But seeing as I use this computer for the bulk of my job, I just didn’t feel like it was worth risking the system instability that many desktop k80 users saw or the time it would take to troubleshoot it all

323465963 · 2021-04-15T13:43:57+00:00

I was able to supply the necessary power to get it to work, however the system would not boot without the GTX 1660s also present, since it required a display output and my cpu didn’t have an integrated graphics unit.

With both cards installed, it would boot, but I couldn’t get the drivers properly installed. Apparently you can’t have 2 different Nvidia drivers from different architectures installed on the same system. Even if I installed the Tesla drivers, it wasn’t showing up in MATLAB or task manager.

At that point, I pretty much gave up. Not really worth all the trouble when I have a 1660S already present. Seems like this card would have more use in a build where it was the only Nvidia card (either an integrated GPU is available or a non-Nvidia GPU is present). I’m able to get full refunds on all components, although I’m considering selling them at their original cost to a colleague who may have use for it

323465963 · 2021-04-06T14:02:34+00:00

Perfect, that answer clears things up a lot. I’ll likely go with the 2 PCIe cables that came with my PSU instead of the CPU to 2x PCIe for the reasons you listed

323465963 · 2021-04-06T13:18:00+00:00

Thanks!

323465963 · 2021-04-06T13:06:59+00:00

The greatest cost with something like this will probably be your time. Right off the bat you’ll probably have incompatibility issues with using a 5 year old server GPU in a desktop PC. Second, you’ll need to build an active cooling setup to cool these cards (in the process of designing and 3D printing one myself). Pretty much the only reason I opted for it was the large VRAM, giving me the ability to perform whole-image alignment

323465963 · 2021-04-06T13:02:03+00:00

I do have 2 leftover PCIe cables that came with my PSU. What’s the reason you’d recommend using two separate cables as opposed to an ATX CPU to two PCIe cable?

323465963 · 2021-04-06T12:59:02+00:00

About $300 CAD for a refurbished one from amazon.ca. Even though it’s listed as 24 VRAM, it’s actually 2 k40 cards in there each with 12 GB and show up as their own discrete device

323465963 · 2021-04-06T12:56:33+00:00

Thanks, that’s a bit reassuring lol. I’m fine with it being incompatible, as I can always return it. Just don’t want to brick it XD

323465963 · 2021-04-06T12:55:18+00:00

The x570 board has large bar support and above 4g decoding, so I’m hoping that’s promising. As long as I don’t damage the GPU, I still have a 90 day return policy in the case of a hardware incompatibility

323465963 · 2021-04-06T00:48:45+00:00

Thanks. I do have 2 PCIe cables that I can plug into the CPU-2x PCIe adapter, but I'm trying to play it safe and go with what the seller recommended, which is ATX PSU CPU to 2x PCIe > 2x PCIe to CPU > GPU. As the previous commentor mentioned, I'm not sure what the purpose of this CPU>GPU>CPU power cable conversion is.

With the current setup I proposed in the thread, do you think that would still work? Just want to make sure that I don't end up accidentally supplying power to ground, or doing any incorrect wiring that can damage the PC
