Folding Forum

Okay I fired up a small dedicated folding rig the other day, I've been running one SMP and one GPU client.

My GPU is an EVGA 260 at stock clocks.

The GPU client has failed every 353 WU (5765,5766,5767 and 5768) 131 in all and will sometimes pause my client for 2 hours.

I have been able to complete 353 WU 5769 and up.

All other WU have completed with no failures at all.

Why am I only failing the above WU??


I used GPU tracker to set up my clients FYI

Please post your FAHlog so we can help you. Also make sure that you use the -verbosity 9 flag to make the FAHlog more detailed which will help us in troubleshooting.

Here is the last one that failed. This is the first time I used GPU tracker. I normally use the console version. So I'm not too sure how it's all set up.
I thinks it's odd that only certin projects are failing, ones I consider easy. The "harder" ones have never failed.

Have you ever run the MemtestG80 test program on your GPU?

No, I've used ATI to test my cards before.

Although this request is specifically addressed to owners of ATI 4000/5000 GPUs, the same software works for your GPU. I recommend that you try it.

I know you said you were running at stock clocks, but reducing the clock rate still might help, particularly if you have low voltages or too much heat in your case.

Better cooling might help, too. What's your fan speed?

Temps are 56c this 260 runs way cooler then my 275's.
I posted this problem over at EVGA's forums, I didn't realise this but alot of people are having issues with theses WU's and the 200 series cards. Is this a know issue by Stanford?

If you mean that Project 5768 is "problematic" for 200 Series GPU, then I have folded ~ 104 of these WUs on my GTX 260 without any issues.

Then that confuses me further. I've only been folding for a year and a half but I've never run into this issue before. This card folded for months without any issues, then I put it in a different rig and now I'm having issues.
Do you think it could be a driver issue cause I did just download the latest NVIDA Beta drivers?

There seem to be almost constant changes to GPU drivers right now. Many of those changes are game-specific and don't change anything for FAH.

We do NOT recommend running beta drivers. There are good reasons to wait for a fully tested and approved set of drivers. What you do is ultimately your own choice but we have seen more problems with beta drivers and I don't ever remember a FAH problem that was solved by them.

Well, I have no knowledge about GPU Tracker hence am not aware if/how it interacts with the F@h Client. You have stated that this is your first time with GPU Tracker so maybe you're doing something wrong. BTW if the F@h Client were to pause, it would be 24 hours not 2 hours.

To begin with, what is different from your previous rig and this new one? Corrupted Drivers? Incorrectly installed softwares? faulty hardware? etc. Also since you're using GTX 260 and the rig is dedicated, you ought to be using 258.96 WHQL Drivers since they are A) WHQL and not BETA, B) Is recommended for folding. Please note that your GPU can run GPU2 or GPU3 BETA Client and both are available in Console Versions (GPU3 Console version can be downloaded via my GPU Guide; link in signature). Also the -forceasm flag is useless for GPUs as they don't use it.

Thanks panther, I'll try you suggestions. I use the console version on all my other GPU's may be time to reinstall the drivers and console client. Thanks for the input guys!
