How to Modify Your HD2900 BIOS Clock Frequencies by Hex File

[Guz]

31 fps --> 34 fps = 10%
743Mhz --> 820 Mhz = 10%

I seldom see games respond to OC as well as this.

To compare (my results):
743 core gives 40-42 in Crysis
900 core gives 50-55 in Crysis.

Settings:
x6800 @ 3,5
Crysis: 1680 x 1050, everything at 'Medium', No AA.

Sounds good and all but at least in my case i cannot get the cards stable past 850 on the core. Increasing vgpu does completely nill to the setup's stability. Furthermore some games get artefacts past a certain overclock. Also heat is not on issue since both cards are watercooled. I guess for me a ten percent increase is not really worth it.
