Yeah I had to underclock my Gigabyte 660Ti with "default OC" too, but I was still able to let it run higher than nVidia spec clocks...
Now I'm having another problem: I want to run my older GTX 275 on the first x16-slot, and the GTX 660Ti on the second x16-slot (which would then only run on x8 speed, I know).
the reason for this is that the 275 has AC air cooling on it and runs much cooler, and being closer to the CPU, I have generally lower temperatures this way.
My problem is though, that now I'm not able to fold at all with this setup. single cards no problem, but not two cards mixed like this. Does anyone have an idea why?
