On my new rig I'm using G-Skill DDR3 1600Mhz memory. My motherboard, however detects it and sets it at 1066. Should I just crank up the multiplier or the base clock to get to 1600? And should I be worried about data corruption?

Also, are there any good tools for testing my CPU on full load for overclocking? I tried a couple apps a while back, when I first got this machine, but they didn't support Core i7 yet (I have a 920.) I don't want to do much, just crank it up to 3GHz maybe.

Also any other general advice? I'm new to this sort of thing!
