How to Modify Your HD2900 BIOS Clock Frequencies by Hex File

[NEvolution]

i would try 1 of 2 things... 1st i would try a different manufacture bios such as the asus bios or ati or vice versa. going from a ati bios to asus bios makes the system re-detect the entire card.
2nd i would try a different version of atiflash or atiwinflash

hope it helps

Could you possibly PM/send me the latest version of atiflash?

I haven't been able to get ATIWinFlash to work properly.
