Overclocking
Ok, so I haven't yet gotten around to overclocking my Core i7 processors, but I asked Geoff to give it a try, and here's what he managed to do with his Core i7-920.

Although the 920's upper multiplier is locked, he was able to increase the base system clock—which CPU-Z labels as "bus speed"—in order to raise the core speed. Using that method, he made it to 3.3 GHz, which isn't too shabby.

Then again, I think better things are possible, but I need to play with these chips a little more. Come back later, because I'll update this page once I have something to report. Shouldn't take too long.
