I have my Radeon9600Pro AIW overclocked to 490/360. I occasionally get a thin black line appear on the screen for like half a second. It doesn't do this when it's clocked at 400/300. It runs, however, with no artifacts at all clocked at 520/380 on everything else such as 3Dmark, Halo, CS, Homeworld2, or even looping vertex shader 100 times on 3Dmark. What could be wrong with it?

Some games may push certain aspect of a graphic card more than others. Overclcoking my 7500 I could get through almost all of 3Dmark2001 at high memory overclocks but certain parts would start ?screen tearing?.
