Recently I purchased a AIW X800XT upgrading from my 6800GT of course I did the usual format C:\ reinstall windows all the usual and loaded Cats 5.3 with the CCC. I loaded ATI Tool v.0023 on my computer so I could just get a good idea of the MAX temps I will get on the gpu at stock settings 500/500. Well when I load ATI tool and hit the check for artifacts button it always detects 1 or 2 artifacts and keeps resetting itself. The really weird thing is is when I run the 3dview for about a minute then press the check for artifacts button it says it detects none but I still see 1 pixel in the lower left corner of the cube that is flasing white or yellow. I downloaded the .24b beta and when I enable the Old Artifact tester it does fine and runs with no problems at all. I have never OCed this card and I do not plan to is this a fault with the program or my video card? Pls someone with a AIW X800XT could you check this out for me.
