Running on eVga 460 O/C @ 806.

Began to suddenly get NAN's with GPU 1. Tried several times to run work unit but got 5 failed.

Code: Select all

GPU 0 in main slot was running just fine.
Stopped pc and swapped GPU's now GPU 1 (now gpu 0) continues current w/u just fine without errors.
GPU 0 (now 1) began getting NAN's immediately and timed out.

Hello rickoic,

Did you try to either delete the core and/or the WU then try it again? If so, I would probably re-setup the FAH directory it was installed to.

These are just basic questions from me as I have limited knowledge with multi-GPU systems, but someone else should be here to help soon.

I hope I helped a little.

Signed,

I did try that and got the same w/u d/l'd after deleting all files except the client, and the dll's, with the same results.

Tks

I'm not sure I understand all the numbers in your sig. Are you saying that both GPUs are identical hardware (and therefore interchangeable as far as drivers are concerned)? If so, it's clearly some kind of hardware failure (e.g.- one GPU won't take the same overclock as the other).

Posted: **Thu Sep 09, 2010 2:26 am**

Both GPU's are eVga 460's. So yes interchangable.
Motherboard has 3 16X slots so I also tried slots 1 and 2, and well as 1 and 3 with the same results.
Thought of the OC factor so lowered it to 794 which didn't help.
Like I said the GPU that was #1 GPU (which was doing NAN's) worked just fine when moved to #0 GPU.
GPU which was working fine as #0 GPU began giving NAN's when moved to GPU #1 whether in slot 2 or 3.

Tks
Rick

When you interchanged #0 and #1, did that mean pci-e slots or did it mean data directories or did it mean both?

So is it a bad WU or has it been true for a whole series of WUs?

Posted: **Thu Sep 09, 2010 3:05 am**

This is what I can understand: (I hope that I am correct; if not, please correct me)
GTX 460 A in PCI-E Slot 1 = Folding
GTX 460 B in PCI-E Slot 1 = Folding
GTX 460 A in PCI-E Slot 2 = NANs
GTX 460 B in PCI-E Slot 2 = NANs
GTX 460 A in PCI-E Slot 3 = NANs
GTX 460 B in PCI-E Slot 3 = NANs

So here are some questions/suggestions:
Is your PSU powerful enough to support 2 X GTX 460?
Rather than reducing the OC, return them to stock or lower to see if the problem goes away
Have you tweaked any unknown BIOS settings?
What driver version are you using?
Are you using SLI? If no then enable it. If yes then disable it.
Use GPU A only in the system and test each PCI-E Slot, repeat with GPU B. If there are no errors, then it might be a motherboard issue

I'm not sure if the information is useful, but Project: 10632 (Run 66, Clone 44, Gen 3) has been successfully completed by someone so its NOT a bad WU.

Posted: **Thu Sep 09, 2010 1:51 pm**

Well it may not be a wu problem for everyone, but wu 10632 (Run 66, Clone 44, Gen 3) was a problem for me.
I erased the wu once again and then threw the -advmethods flag onto my shortcut and started the GPU again.
This time it d/l'd P10936 (Run 1, Clone 0, Gen 6) and is happily folding along. Know its early yet, but it's gotten beyond just Failing and is actually folding having completed 4% so far, with no errors.

As indicated in other post GPU is folding nicely now on a P10936 and is 57% completed with no problems whatsoever.

I am glad that you got the 2nd GPU folding.
