I've got an Daimond S120 Radeon 9550 With 256 MB DDR Ram, which is supposed to be a X8 AGP aperture, but only workd as a X4, I dunno what going on there, tut hats not my main question (I would like that one answered though...) My main question is, My Card freezes up when ever I overclock it to 500 MHz, and I want to know why. It works fine at 480 Mhz, and isn't overheating, in fact, it doesn't get very hot at all... So why does it freeze at 500 Mhz? I've taken off the ATI OCing lock, and I've also taken off the safety range. I don't know whats going on...
