ERROR:GPU with PCI bus 0 and slot 2 not found

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Re: ERROR:GPU with PCI bus 0 and slot 2 not found

Post by PaulTV »

Hi,

Something like taht happened on my machine a couple times as well, and it's quite annoying.

1) Stop the client (not only folding, but also the background fahclient process)
2) Remove GPUs.txt (on Windows in C:\ProgramData\FAHClient, on Linux in /var/lib/fahclient)
3) Start the client

Hopefully that'll fix it for you as well.

I still don't know if the gpus.txt gets corrupted during normal operation, or if this is because the computer may not have internet access yet when the client is started. The next time it happens to me, I'm gonna save the GPUs.txt file and make a case out of it.

Re: ERROR:GPU with PCI bus 0 and slot 2 not found

Post by Neil-B »

Slightly confused ... your first post implies you had just started your pc this morning and got this error - which might indicate either no Internet gpus.txt issue or the drivers updating possibly as part of a system update as part of the shutdown/restart ... your next post implies you started fachlient to give the problem which I'm not sure I understand - dud the problem exists before you shut down?

I don't understand what is confused.

Yesterday no problem.
I start my PC this morning then I saw the issue.
Then I fixed the problem by restarting fahclient.

Last update of nvidia driver : 2021 november

I already told you multiple times that you need an active Internet access at client startup ...
