Greetings,
in the last days the failure rates of GPUGRID using is increasing. Here are some failure reports:
<core_client_version>6.10.13</core_client_version>

I think the most of this failures I get when I started a HD-Video, Games (it is irrelevant if I started the game when boinc is running or not).
Can anyone help me please to minimize the failure rates.
It is very horrible if u running GPUGRID for 10 hours and it fails.

Thank you for all your hints.

Probably, your card is overclocked ? According to official nVidia specs, you card should run with 1,625 GHz shader clock, if it isn't some kind of a special vendors edition, factory OC'ed. Try to get the core temp reads, as well. Check the overall temp in PC case. Overheating with or due overclocking could result simultaneous & unpredictable calculation errors.

Hi,
the pc temperature is ok, the card is an AMP! Edition so it is factory-overclocked. But I think it is not the reason, because weeks ago under Win XP 32bit/Win 7 64bit GPUGRId runs very well, it is a lately problem.
That's the reason I put some problems in the thread here. Because it seems that are different failure's?

Hi,

I recently saw that I had an increasingly high WU failure rate on my i7 system with a GT295 card.

I reset the project and found I was still getting about an 80% failure, with both concurrent WU's failing at same time.

I had recently upgraded the NVIDIA driver to the latest offered. I backed out this upgrade and it appears the system is now running happily.

Hi,
I am also experiencing similar problems with my new GTX295
http://www.gpugrid.net/result.php?resultid=1547063

I have the lastest NVIDIA driver, so that may be the problem? Dave, could you please provide driver version information so that I may install the same ones?
