Folding Forum

This one's given me fits. I can't rule out machine instability as the WU failed at a different point 12 times in a row. Wiping Work dir and queue.dat didn't cause a different WU to be downloaded, but adding -advmethods did the trick. This is on a GPU that has completed 8000+ WUs, but instability has to start somewhere. I did a clean install of the drivers, 266.58 in the middle of the failures. If the WU has been completed by someone else, at least I'll know to change cards.

[23:39:04] Completed 700000 out of 10000000 steps (7%).
[23:39:05] mdrun_gpu returned 52
[23:39:05] NANs detected on GPU

[23:39:05] Folding@home Core Shutdown: UNSTABLE_MACHINE
[23:39:07] CoreStatus = 7A (122)

There's no sign of it in the WU database yet so it may be a bad WU.

Thw WU folded successfully:

Your WU (P10117 R719 C1 G7) was added to the stats database on 2011-03-10 18:07:22 for 494 points of credit

Thanks. Strangely, as of the 18th, the card in question had not failed a WU since the p10117.
