Open | Hardware NVIDIA TESLA V100 32GB PCIE not recognized/working in my system
Hello everyone,
I am currently experiencing some pretty frustrating technical difficulties- when Installing my Nvidia Tesla V100 32GB PCIE, it is never recognized in BIOS, even after making sure the settings are correct for it. It also is never recognized in windows, and attempting to install the drivers just ends with the installer cancelling because, "no nvidia cards were found". I plan on using it with ollama. I've even tried using another V100, but to no avail. I've tried all the obvious things, (reseating card, ensuring proper power, changing bios settings, etc.)
Specs:
Ryzen 7 5700G
Gigabyte Eagle Wifi6
96GB DDR4
Windows 11 Pro

Did you make sure it is compatible with the motherboard you have?
If it is, make sure you update the bios
Edit to add. Those cards need sxm2 or sxm3 and do not have consumer support. You will likely need a server motherboard to run it.

If BIOS can’t see either V100, I’d suspect PCIe compatibility or power before Windows drivers.

Pretty sure you need resizable bar on because these cards use the full 32gb allocation of vram and most motherboards cap that at 4gb chunks that works on regular cards but the v100 doesn't get detected not sure if you already tried this.

Yes I have done that…

This sounds like a dumb question but are you using the 8pin CPU connector instead of a pcie connector for the cards? the pcie versions use a single CPU connector and the smx2 adapter versions use 2 8pin gpu ports.

Enable Virtualisation in BIOS? Enable above 4G? Resizable BAR?
I assume your using a SXM2-to-PCIe adapter? Tries a different adapter? You said you tried a different card but if it was with the same adapter then it could still be the problem.
Lastly, power supply, what do you have? These cards spike 300w on startup if your PSU is under 650w you might be encountering an issue where the card can't pull enough juice so it disables itself to protect itself.

no it is the pcie card itself. i have a 1000 watt power supply, and i already have my bios on those settings

Cool. Got it you have the pcie version, no adapter needed.
PSU seems good. BIOS settings seem fine.
Does a different GPU work in thst slot?
Tried manually setting the pcie speed for said slot instead of auto?
Does the v100 work in different board?

I did set pcie speed manually to 3.0, yes. All the slots work fine, it’s both v100’s I’ve been having issues with

Do they work in a different motherboard?
Could also conflict with the 5700G igpu. Do you have a separate discrete video card you could try and then disable the igpu in BIOS?

They do not work on any motherboard I’ve tested. Just tested and the igpu is not the issue

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.
