Overclocking my X1900 Connect 3D Crossfire Edition Graphics card

post #1 of 3
Thread Starter 
I am trying to overclock my crossfire edition X1900 graphics card to a very high performance but am pretty much stuck running at 668/774. If I try to push my graphics card past that the screen during gameplay will go to pixel distortion to where I can't tell where am (basically the big color pixels take over the screen). Does anyone know how I can fix this problem because already I am past X1900xtx speeds and would like to touch X1950 speeds if all possible. Thanks

Using ATi Tool beta 14 or 16 and upping voltages to get higher clocks. Though most really seem to pitter out at ~730 on air cooling and ~760 with water.

The dots on your screan is artifacts (that your gpu or mem is running to hot). You need an extra cooler and you shold be fine....
