nans detected on GPU, UNSTABLE_MACHINE

hat · Jan 16, 2009

What's up with the F@H GPU client? I keep getting errors that say "nans detected on GPU, UNSTABLE_MACHINE error". I googled it and there are lots of people on the F@H forums having this problem. People who don't overclock anything. What's up with F@H?

bump.
nobody can confirm this?

Its a bit after you posted this, but I have the same problem on my second GPU - GPU is stable. I get NANs only on 57XX WU's

ati or nvidia? which driver version? which gpu client version?

wtf is a nans?

phanbuey · Feb 11, 2009

NANs - not a number... its nvidia GTX 260 - only the second gpu (GPU 1) - GPU console version 6.23 - drivers 182.05. Consoles are set with -gpu 1/0 flags, CPU affinity locks are disabled. Two different consoles in two different folders.

It only happens after a 353 point WU from 57XX, and only after the WU finishes. I have to delete queue.dat and work - then it downloads a different WU and runs sometimes for 24 hours until it gets another 353 point 57XX. Meanwhile GPU 0 chugs along just fine... ive swapped the cards - no matter which card is GPU 1, it crashes - regardless of clocks (it crashed the other day at 500 core 1200 shaders and 900mem) - same card is game stable at 756 core and 1566 shaders.

yep 5765 and up 353 pointers... what can I do about this? Its annoying to have to delete the work files and the queue everytime. Can I disable these WU's from getting assigned to me from the client end?

stanhemi · Feb 11, 2009

From what i understand you have to deleted the work folder contents and the queue every time
