How to Modify Your HD2900 BIOS Clock Frequencies by Hex File

Can confirm that at least Crysis scales very well with higher clock on GPU.

How well is "very well" ?? For me an overclock of 820/950 only meant going from 31 fps timebench at stock speeds all the way to a mere 34 fps. That's like a ten percent increase but really gameplay-wise i consider that mediocre at best.

[roger_h99.nor]

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.

The 2900 is nearly completely GPU bound. Too much memory bandwidth for it's own good.
