Hi,

I had a 100% failure rate on my notebook system with a 8800M based video solution running Vista 64 bit.

I tried resetting the project, no joy.

I then backed out Boinc 6.10.18 and went back to 6.6.38.

System is now processing GPUgrid WU's successfully.

I have also reverted back to 6.6.38 on a Windows 7 64 bit system with a GTX 295 card installed that was running WU's successfully, and it seems I am getting a higher daily credit from that system.

At one stage it was suggested the problem on the system with 8800 may be heat related. I run TThrottle throttling software to protect my systems from heat and they were not reaching the upper end of the recomended heat range, so this was unlikely to be the cause.

I suspect that Boinc 6.10.18 (and 17) have a problem in the GPU handling area.

Hope this helps
