Has failed twice at the same point with the exact same error. Ive done maybe around 100 units of this project prior to this one dying, so doubt its hardware related. Ive scrapped it, and am now folding a different workunit from P8010.

System is GPU on Linux Wine (yes i know its unsupported, but considering ive been doing 3-4 of these wu per day for over a month without a single problem, id lean towards a wu problem), V6.41r2 client, Stock Nvidia GTX 460.

No WUs have been returned to the server, but I can see from your log that V6 removes the WU from the queue without making a report. That's one of the issues that V7 is supposed to fix.

The nonzero force sum means that the GPU failed the self-test. Have you tried underclocking?

Cant change clocks on linux. Can do it on windows. The things that gets me is its done so many of them and now i have an error.

The one i got after is up to 49% so far, if it completes i'll put it down to a quirk. It will complete.

I always wonder whether to report stuff that happens on this box, due to its configuration.

BTW, i have the work directory, should anyone have any interest in it, since it was upto 10% on the third run when i killed it and tarred the dir, then wiped it out etc, so i could get something different. But if someone has need of those files i can upload it to my web server.

Please do.

I won't be able to do anything with it personally, but the folks that work on problems with the FahCore can try to reproduce it. If it processes past 38% they will have to assume it's a hardware issue with your system (i.e.- actually "Unstable Machine") but if it's reproducible on their machine (as you suspect it will be) they'll be able to learn something from the failure.

Well since that one failed ive done 2 more units from P8010 without any problem.

So here is the work/ dir for anyone that might find it useful.

P8010R0C1943G42.tgz

Another folder was able to complete this WU:

Hi xxxxxx (team xxxxxx),
Your WU (P8010 R0 C1943 G42) was added to the stats database on 2012-09-06 23:08:13 for 2510 points of credit.
