ATI Radeon X800 XL Videocard
 

The first thing we did was set the memory to run at a full 1 GHz and it had absolutely no problems running at that frequency. Playing nicely, we then raised the memory speed in 4 MHz intervals and 1.01, 1.02 and 1.10 GHz fell by the wayside. The maximum speed we got the memory to was 1.11 GHz, very good for an ATi Radeon X800 XL class videocard!
