Maximum PC

Slot 0 has a GTX570, Slot 1 has a GTX460. Both are SuperClocked EVGA models. Both have folded in the past, but problems led me to wiping everything and doing a fresh re-install. Since, I tried to set up a slot in the F@H client (v7.2.9) for the 460 on 2 occasions. Both times, it ran one WU, then failed to start a second one due to a Memtest error.

MemtestG80 and MemtestCL report no errors
GPU-Z reports no CUDA for the 460, but the 570 has it
Drivers for the GPUs are dated Dec 2012
CUDA was freshly downloaded and installed this morning, yet no CUDA for the 460 in GPU-Z

Is the missing CUDA the culprit? If so, does anyone know how to correct this? I've Googled myself silly trying to find an answer.

I am running a GTX 460 and a GTX 660 on the same pc and haven't had any problems, GPU-Z 0.6.7 doesn't show any cuda cores for the 460.

UR Quite correct, no cudies.

Thanks for the responses.


Scroll down that page and the 460 is listed with the CUDA-enabled GeForce products.

OK, so CUDA isn't my problem, though I'm still curious why it doesn't show up in GPU-Z. Guess I'll run the Memtests with more iterations to see if anything shows up. I might resort to switching the 570 and 460 around.

I believe that only one GPU runs cuda at a time. I've run multiple GPUs often and that is always how it shakes out for me. I doubt that's your problem. As to what your problem may be, I couldn't tell you. Have you tried folding, evga, [H]ard, or other forums? They may be able to help a bit more or provide some better insights than we can here.

I'm currently running a 650 Ti and a 460 and last time that I checked at most, one has CUDA enabled and both are folding without issue.

It's a bug in the GPU-Z program. I've folded with multiple cards and they all worked fine. However I am not using the FAH Client.

I think you hit the nail on the head. One of my folders has a GT 640 used exclusively for folding and the primary display is actually crummy onboard graphics, GPU Z reports the 640 as OpenCL but not CUDA, but it folds fine. I use the v7 client
