Another one on the same project -

had Nana error with another 6805 before
just did 9 in a row with no issues till this one
and the WU one after this one works fine

Xavier, was this the same GPU as viewtopic.php?f=19&t=17852&p=177951&hilit=returned+52#p177951

This might signal a problem with the GPU.

yes it is
been folding with no issues for 3 months
mind you it's been up 24/7 for last week...

it did 9(6 of them 6805 projects) after the first fail
and it worked the next unit after this one fine

I think it just needs a quick reboot - to shake some cobwebs out
It's only when I run the card long - for a week I have issues

I have seen issues with fermis on card issues when running 24/7 for long extended periods in NVidia Forums

No data i the WU Database yet so I have marked it for a follow-up.

I know my XP machines get flakey if they run for too long. 7 and Vista no problem but XP another story. All of them run SMP. Let us know how it goes.

I'll know more in a day or two, but it could have been unstable... the reboot has the card folding 100% no errors and my production has improved

Must be a problem somewhere, my XP GPU rig stayed up for weeks at a time, only being shut down for a heatsink clean or upgrade. my current main use rig folds 24/7, games etc and it has no issues either - and this is a botched reinstall over several other reinstalls

It's stable now 3 days with no errors...all I did was a reboot

The WU has been completed by another donor:
