There we have it. It is certainly not as difficult as you would think to overclock your video card, and the rewards are certainly rewarding if you can overclock far enough. If you're having problems with your overclocking, make sure you follow the steps exactly, and everything should be fine. Otherwise email me and I'll see what's wrong.
Remember - Be sensible when you are overclocking as you certainly don't want to damage an expensive PCB. At any sign of danger, throttle back and go from there.
