I got a Koolance Exos and Kookance NV2 water block and now my temps are 38C idle and 53C load during rthdribl. With my NV Silencer my max OC was 418/1140mhz @ 74C.

I decided that with such an improvement I could bump my voltage to 1.4v and OC further. I ran the nvidia optimal OC thingy and it reccomended 456/1190mhz, tried that in 3d mark and with no surprise it failed, frozen with pixelation/crazy colors all across the screen.

I tried 435/1150mhz and ran 3dmark, not a single white dot or irregularity, even on the turtles back in the nature demo. However my problem is that in World of Warcraft I see the heavy pixelation/ colors all over the screen anywhere from 1-30 minutes of play. Bumping the AGP voltage to 1.6v helped extend the time before it crashes but I'm afraid to take it to 1.65v and see if that makes it better.

What could I try doing? I have a very good PSU so I doubt also having my CPU overclocked would have something to do with it.
