I've just returned to Seti after a few years lay-off and have started running a cuda version - with all latest drivers from nvidia. I've run a couple of hundred wu's pretty quickly without problems, but now it's getting computation errors on a high percentage of them. Not only that, but there's an error message at my end saying nvidia driver nvlddmkm is not responding, but the drivers have recovered. O no they haven't - my screen becomes mush, compounding with every wu that goes wrong. After three you can't make out anything. System reload cures it, and no obvious damage to anything. As far as I know I've got the latest everything as far as software is concerned.
H/w is GeForce 8600GTS. Anyone getting the same? What can I do?

Read this thread to know what information I'd like and to recover, reboot the computer. I think your GPU is stuck, which can only be overcome by rebooting the computer.

Thanks for response. The system is Vista 32 bit Home Prem Sp1 (06.00.6001.00), the nvidia drivers are 7.15.11.7824 (7 Oct 2008). The cuda error reported is consistent over many tasks -

Cuda error 'find_pulse_kernel2<3, false>' in file 'c:/sw/gpgpu/seti/seti_boinc/client/cuda/cudaAcc_pulsefind.cu' in line 1166 : unknown error.

The task gets aborted at that point.
Tasks invloved include 1097806722, 1098421568, 1091826354, and many others.

The GPU doesn't seem to be "stuck" as after the reported "recovery" of the nvidia drivers, following the error, everything carries on running. It's just that the individual pixels are not being displayed in the correct locations on the screen. This degenerates after each occurence of a cuda error and "recovery". Only about 10% are (seemingly randomly) wrong after the first error and recovery, but after the third virtually the whole screen is a dancing "mush" of random pixels.

Cuda error 'find_pulse_kernel2<3, false>' in file 'c:/sw/gpgpu/seti/seti_boinc/client/cuda/cudaAcc_pulsefind.cu' in line 1166 : unknown error.

OK, I have reported that one for Vista 32bit with 3 different driver versions to the developers already. Thanks for the report, though. :-)

I'm having the exact same driver issue with Vista 32 bit.

I'm running the latest 180.84 drivers on an 8800GTX.

Hello,

same problem here, I had several messages "Display driver did not respond and was restarted", the following WUs crashed too until I rebooted the PC:

Vista Ultimate 64bit
8800 GTS (512MB) - Driver 180.48

2 Examples:

WU 384603180

"Cuda error 'find_pulse_kernel2<4, true>' in file 'c:/sw/gpgpu/seti/seti_boinc/client/cuda/cudaAcc_pulsefind.cu' in line 1172 : unknown error."

WU 4384172

"Cuda error 'find_pulse_kernel2<3, false>' in file 'c:/sw/gpgpu/seti/seti_boinc/client/cuda/cudaAcc_pulsefind.cu' in line 1166 : unknown error.

Hi,

I've got the same problem as well, and have also tested GPUGRID units in order to see if this is indeed a hardware issue or not. GPUGRID units are completed without a hitch, so hardware is not the case (some mention blown capacitors, or insufficient power/PSU etc.).

My system:

Vista x64 Ultimate SP2
Asus GeForce GTX 260
Cuda 180.84
