[QUOTE="petekill, post: 220195"] I spent last night trying to upclock (not really over-clock) my graphics card in my 15" MacBook Pro 2ghz, 1gb ram. I got windows installed, bought Half-Life 2, and ran it. It ran very decently at 1440x900 resolution and all visual settings at "high". I was very impressed and very pleased. I have read about how Apple underclocked the speed of the ATI x1600's in our MacBook pros, so I decided to see what I could do about it. I downloaded ATI Tool, and sure enough, my GPU was running at 310 mhz proc/290 mhz memory. It took me a while to get it stable while upclocking it, but I got it to 400/400 no problem. The results are amazing 20-30 fps increase in HL2, without too much increase in heat. The fans come on and off, but its not getting too hot at all. When I'm not running games, I clock it back down to regular to save battery/heat. I can't say I suggest doing this, as it can cause crashes and data corruption on your WinXP partition, but if you know what you're doing, its a good modification. [/QUOTE]
