LOL @ annisman
I had one hell of a time getting drivers to work correctly for my 8800gt when playing cod4 (cod4 would freeze on me a few seconds into play, even at stock clocks).
I had to use the modded DNA drivers based off of the 169.04 beta.
My card was stable with the settings below, but I uninstalled them because I wanted the control panel. After several other drivers that failed, I gave up and went back to the DNA ones. Now I can't overclock
. (its not heat cause I have a 120mm fan blowing on my gt).
I really think the culprit is my chipset. I have heard that ULI is very picky...
