    I'm running windows XP on my macbook pro using bootcamp. First problem is that I dont get any performance improvement after quite drastic overclocking: core from 300Mhz to 475Mhz.
    Problem 2: if I try to increase memory clock, my performance is getting lower. Not much, but it is definately not better even if I put it on 475Mhz.
    Knows anybody how to fix it???

    What may be happening is that it has some kind of fail safe thing on it where if the chip gets too hot, it will clock itself back down so it doesn't overheat. Also, some video chips are better than others for over clocking. You're not always going to get the results you expect when overclocking. Also remember that if you kill your MacBook Pro from doing this, its NOT covered under warranty so be careful of how high you go. Higher clock speeds, equals hotter temps which the notebook may not of been designed to cool.

    Maybe that will be some help to you...
