Unhide your computers, please. It's much easier to diagnose your problem when people can see all the available information.

OK.Thanks for the notice.
My cpu is AMD Athlon II 640,but the website is shown AMD Processor model unknown. I used LinX to do the stress test, it was working stable.

If you look at the task on the website http://www.primegrid.com/result.php?resultid=542444048 you will see MANY occurrences of this error:

maxErr exceeded for 405052^1048576+1, 0.5000 > 0.4500
MaxErr exceeded may be caused by overclocking, overheated GPUs and other transient errors.
Waiting 10 minutes before attempting to continue from last checkpoint...


Each of the 10 minute pauses causes the "program terminated with zero status" errors in the BOINC log file.

That's a hardware error on your GPU. It's almost always caused by overclocking. Even if the card came "factory overclocked", it still is overclocked and that's what's causing the error.

You need to lower the clock speed on the GPU to get it to run Genefer reliably. We've found that lowering the memory clock speed is more important than lowering the shader clocks.

Genefer stresses the GPU much more than other programs or normal usage, and is much more sensitive to overclocking than any other program I'm aware of.

I understand, I will set the card back to the default frequeene and try again.
thanks for your help.
