BTW: The GTX 680 can work as two GPUs if you add it as gpu-index 0 and 1 it's running as gf:114 and gk:104 at 37-45k PPD

What is ppd with only one GPU slot running?

Holy crap, it seems to be working.

Any word on how this is possible?

Note: MY PDD on these 2 WU's I had both dropped down to about 8000 and TPF went up on both slots, about what I would get on 1 680 slot. I might keep at it later on this week.

I have a very similar problem but unfortunately I am unable to get the GTX 680 to start folding. Details of system are below. I am running the most recent client and have also downloaded the GPUs.txt file into the FAHClient folder. Is there any obvious reason why the other users here can get the GTX 680 working but I am not able to?

Paz, it may be related to a fact that the FahCores for Kepler-class GPUs are still in a beta testing stage, and AFAIK haven't been officially released. If this guess is correct, I'd recommend that you search around the forum using terms like "Kepler" and "beta" and I'm sure you'll find the key. Technically, I'm not supposed to talk much outside the Beta Team subforum about the setting you may need to change to make it run....
