I picked up a cheap-o 9600xt for BF2 (which does a fantastic job, 50+ fps with most stuff on medium, good enough for me) and I was messing around with overdrive and looking at how it would increase my fps by a few. I've dicked around with my GF4 a bit and figured I knew enough. So I got ATI-Tool, let it work it's magic for a bit. Let it hit it's limits and then turn it turn a bit from there. My temps in games hovered around 50's tops. ATI tool would put that almost into the 60's. Anyway, when it started finding the errors I toned it down a bit and didnt quite hit that button that applys it. I moved over to my overdrive window and was just watching my temps move around while ATI tools tests thingy went on. In an atempt to move that window and somebody calling me I managed to hit the overdriver checkbox and my screen became somewhat garbled and ATI tool let out it's fabled error beeps. Needless to say that scared the shit out of me and I turned off the computer pronto. What the fuck was that, why did hitting that make it go so ape shit. :X Everything seems fine and dandy now, no fires, didnt smell anything cook, but damn that almost gave me a heart attack.
