Overclocking
The card does not use distinct 2D/3D clocks. It always runs at 574 MHz core and 682 MHz memory.
ATITool does not work on this card (yet), so we used ATITool "Scan for Artifacts" in conjunction with ATI WinClk 5.22 to find the maximum clocks manually. Actually ATITool core clock changes work, but when you try to start Find Max it will try to change the memory clock as well and crash the card...
In the end the card runs completely stable at 682 MHz Core (19 % overclock) and 816 MHz Memory (20 % overclock). Both overclocks are breathtaking, I haven't seen such overclocking potential on any video card in a stock configuration for quite a while.
