I overclock backwards from most people. I'll let the chip run 24/7 stock for a week or so, and then I'll shoot right for my goal overclock. For example on my i7 builds I always go for a stable 4.0, so I go immediately to 20x200 w/ 1.32v....it almost always works, so then I back off the voltage until I get it as low as possible, and stick there. It can save a lot of time compared to slowly creeping up the clock speed and then messing with voltages.
