What are some relatively good parameters for overclocking a radeon 9100 (non igp)? I am just looking for some reference points to see what other people have come up with. I have downloaded Atitools and installed it. This post is for my Dad. He builds computers occasionally but doesn't do any tweaking. I bought Medal of Honor Pacific Assault for him and it chugs like a locomotive. He has an Atlon 2400+ w/ 768m of memory. I wanna hook him up as well as possible without a major upgrade. Any help or suggestions would be greatly appreciated.
