1.Find Max Speeds (ATi Tool), back down a bit for headroom.
2.Test temperature @ OC Speed (Ati Tool)
3.Find Shader speed using ati tool + rivatunner.
4.Modify bios with Nibitor, (Core/shader/memory speed)
5.Flash bios in dos, with nvflash. (Dos Command = nvflash -4 -5 -6 biosname.rom)

Thats to make a permanent overclock, you can also just use ati tool but you will always have to have it running.

no problem,

In between step 3 and 4 I grab the original bios in dos with nvflash, but I think there's a way to do it in windows with nibitor.
