So I put my new system together and have begun playing a couple of games. Had a couple of things happen and I'm not sure what is going on.
First I tried the ati overdrive utility to see what I could clock my xfx 5770 at. I upped the clocks bit by bit and ran 3dmark06 after each change. I was able to max the clocks out doing this, I thought that running through 3dmark06 once was enough to see if it was stable. So GPU clock 960 and memory 1445.
First game I tried was Bioshock. Video went out during the intro movie so I backed the clocks a bit from max and tried again. Currently have them at 930 and 1430. Played for a while without problem.
Then I tried Torchlight. Screen changes to completely beige and I can't do anything. First time I was able to hit the windows key and minimize it, second time I couldn't even do that.
Since this is a completely new system, I have no idea what might not be working. Am I just overclocking too aggressively? What else could it be?
