8.5.5 client doesn't detect GPU

Post by BestWeb »

Hello everyone!

My computer runs Windows 11. Previously, I had client version 8.4.4. Everything worked fine on it.
But for some reason, I decided to update to 8.5.5.
And this version doesn't detect the GPU on my computer.

The worst part... I installed client 8.4.9, which worked before. But now the GPU isn't detected on it either.

I haven't changed the Windows version, and I haven't updated the NVIDIA drivers.
I just updated the client, and now the functionality is broken.

Could you tell me what the problem might be and how to fix it?

I also recently upgraded to 8.5.5 and I am getting the same message ("Waiting for GPU detection"), but I don't even fold using a GPU (Intel). Is this the "system information" you requested from BestWeb to help troubleshoot the issue? If not, please provide specific guidance.

The URL I shared says "false" under "GPU: SUPPORTED," and all my other WUs have folded with 10 CPUs using Core: "0xa8," Be that as it may, folding has halted 19.7% into folding Project 19228. Here is the relevant portion of the last logfile:

Your gpu is supported by the client
The URL I shared says "false" under "GPU: SUPPORTED," and all my other WUs have folded with 10 CPUs using Core: "0xa8," Be that as it may, folding has halted 19.7% into folding Project 19228. Here is the relevant portion of the last logfile:

Yes, I am blind. Your GPU is not supported by choice (either too slow, or does not have required hardware to work reliably with FAH).
In system settings, set the CPU slider to 6, and use process lasso to tie fahcore_a8 to your CPU P cores

Re: 8.5.5 client doesn't detect GPU

Post by DrBB1 »

I solved my problem by uninstalling 8.5.5 and reinstalling 8.4.9.

BestWeb, I suggest doing another uninstall/reinstall, but rebooting your computer before the reinstall. If that doesn't work, consider restoring Windows to a point before you installed 8.5.5.

I really don't think OS restoration is required just because FAHclient does not see your GPU. That is an overkill of epic proportions.
Also, you didn't have a problem. Your intel iGPU is disabled by us, and not by specific fahclient version

Make sure any unsupported iGPU is not selected in any group.

I tried to remove 8.5.5. I rebooted the computer. I did unlink/link for the computer in the web interface.
I installed version 8.4.9 again, but the GPU stopped being detected in version 8.4.9 as well.
It's like a mystery... :twisted:
I don't see any point in restoring Windows. Nothing changed in the system. The drivers were not updated, and the system updates were not installed.
Now, I want to somehow make version 8.5.5 see my computer's GPU.

Re: 8.5.5 client doesn't detect GPU

Post by BestWeb »

Maybe I see the problem, but I don't know how to fix it.
I just installed the client, version 8.4.9.
And here's the log when I first launch it...
Am I understanding correctly that "Token" in my profile in the web interface and "F@H ID" in the log are the same value?
But for me, these values ​​are different.
Is this how it should be?
I don't like the second-to-last message in the log :(
If not, how can I make them the same?

My Token (from Web Interface) ---> Y3q8oY3ryvli6y-deleted
F@H ID (from Log) ---> DVUBVFahOd6QR2e-deleted

So client sees what your system presents to it. In Windows it is usually straight forward. If a GPU was detected in 8.4.9 it will be detected in 8.5.5, especially in windows. It is possible that Windows pushed their own driver version, which messed things up, or driver crashed. Try reinstalling the GPU driver, use drivers provided by nvidia

Everything turned out to be much simpler.
We (in Russia) have government agency :evil:
It supposedly protects us from the malicious influence of the West ;)
By blocking WhatsApp, Telegram, and other services, as well as entire subnets of foreign internet providers.
I updated the client by completely uninstalling the previous version.
It turns out that the new version, after launching, additionally downloads some files/data. These are needed to detect the presence of a GPU in the system.
Here's how to do it:
1. Install the new version of the client.
2. Enable the VPN on your computer.
3. Launch the client. The client downloads the necessary files from the internet. The GPU is detected. Configure everything.
4. Shut down the client. Turn off the VPN.
5. Launch the client in normal mode (without the VPN). Everything works :)
