I´ve been running a machine dedicated for SETI alone, for a while. In the beginning, everything was fine. But then I started to get "error while computing" on the wu made by my 8800GT´s. I started to suspect them to be faulty, and replaced them with a coulple of 8800GTS-cards I´ve been running with no faults in my server. And the "errors" are still there. Any ideas?
Hardware look like this:
Foxconn Destroyer motherboard
AMD 940 Phenom II
Corsair XMS2 6400 Dominator 2x2Gb
2x8800GTS or 2x8800GT
Corsair 620W
Everything stuffed into a Lian PC-V2000.
No strange temperatures, and no faults in Prime95. No overclocking.
Freshly installed Win XP.

That would be this one?

There I found

Cuda error 'cufftPlan1d(&fft_analysis_plans[FftNum], FftLen, CUFFT_C2C, NumDataPoints / FftLen)' in file 'c:/sw/gpgpu/seti/seti_boinc/client/cuda/cudaAcc_fft.cu' in line 49 : initialization error.
setiathome_CUDA: CUDA runtime ERROR in plan FFT. Falling back to HOST CPU processing...

followed by

Unhandled Exception Detected...

- Unhandled Exception Record -
Reason: Breakpoint Encountered (0x80000003) at address 0x7C90120E

Whatever that means ;-)

bad driver version? [/edit]

Somewhere down the line something is preventing CUDA from running and it is falling back to the CPU

The breakpoint encountered happened when the task was terminated via abort or an improper shutdown.

Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957
Or Good Shop? http://www.goodshop.com/?charityid=888957

Any idea what causes it?

Hi

Do you have a load on both video cards, either by connecting a second monitor or by using a dummy plug? If so did you also extend the destop to the second "display" in display settings on your desktop?

Do I need to? I havn´t it connected to any screen at all, at the moment.

According to what I've seen posted in the threads here, if you want to run tasks on both cards, you would need to, though I'm not sure it would fix the current error you're having, it might be worth trying.
