Hello! I have problem in Skyrim, that was related to gpu memory clock 2100mhz. Gpu clocks are 940 core and 2100 mem at 1.05v. Clock was stable in Heaven, crysis, crysis 2, alan wake even after few hours of playing, but in skyrim always crash after 10-15 min. I tried raise voltage at 1.062 and 1.075 but it didn't help. Temps are at load 75-78, idle 25, and room temp 22C. Today I installed Oblivion to see what happens with this clock, and it was also unstable at 2100. When I set mem to 2060 it was OK. Is it possible that's mem limit for this card?

when you run Heaven, do you get any color flashes of light or other artifacting, because if you do the GPU needs more voltage to really be stable, in a game like skyrim. Really not sure what your voltage should be, though since I don't have a gtx560 or 560 ti. CHanging the memory clock will also increase the voltage demands, but it also tends to make it more unstable, so either you found the max memory clock or you need more voltage.

Yes, in Heaven I get color flashes, usually purple and green( maybe 2 every 10 seconds). Today I played a little with different settings, and i found default mem clock (2004) and voltage 1.0370 and 930 core and flashes disappear. I'll try increase mem and voltage a bit now. Thx for reply
