Hi,

I have a Powercolor HD5850 and right now when i launch AMDOverdriveCtrl i can overclock past the 775MHz mark.
I've heard that it is possible to get past the 775Mhz if i flash the BIOS and change the BIOS limits.
But i really don't want to do this right now since it will void warranty.

I know on windows it can be done using MSI Afterburner.

Can it be done on Linux by the use of any tool to overclock or opensource drivers?

Thank you.
