Step by step instructions on overclocking my iMac's 2600 in Vista?

[mattcube64]

Hey guys! I play quite a bit of games in Vista, and I'd really like to overclock my card just a bit to get the extra FPS in games :p

But I'm not 100% sure how to do that, as the catalyst control center doesn't seem to want to work.

Get ATI Tray Tools or winclk, check TechPowerUp for downloads or google.

It's as simple as moving a slider so you'll figure it out easily

^^^ Thanks, but I've tried that. Any time I mess with the slider, the computer locks up and I have to do a hard reset... :-(
