So, very recently my beloved HD4870 bit the dust. As it is a Diamond, the RMA process can be quite lengthy. There's no way I can live for months without a GPU, so out came my Visa, and I picked up an EVGA GTX260 SSC 216sp. Needless to say, the 2nd program I tried on it was F@H-GPU. (Crysis was #1, if you're wondering).
Well, imagine my chagrin when 6 minutes later it came up with a NAN processing error. And then a rapid succession of 5 more. I'm hoping that some of you may be able to educate me about the causes of NANs, or at least commiserate with me.
I had deleted the work folder, and re-installed F@H. I'm running 181.22 drivers, and had the same issue with the 182.08 drivers.
I'm kind of lost, and hoping for help. When it runs, it pops along at 7600-8400 PPD until it errors.
Are you using SMP as well? Even if your not don't check "Do Not lock Cores to specific CPU" and put core priority at "Lowest".
If your using SMP then just reduce the CPU usage through whichever SMP client your using to around 92%. You might want to disable any overclock you have on your CPU and try the GPU client alone.
You have pretty much the same card as me so d/l the 182.08 which are the newest and work purrfect..for me.
