I will second that, that tutorial is one of the best I've ever read. and was the only thing that was able to teach me to get stable past 3.6 GHz on my Quad. it's great.. the RAM divider info, and more important for me but not you, the nforce Nvidia GTLREF settings saved me.

either way it's a great read. make sure you get something like a Tuniq Tower, or a TRUE cooler for your cpu, then oc. also I'd not recommend using there software. ASUS software causes problems, and I've heard a few horror stories. don't even use it, and just OC on your own in the BIOS.. much much safer and better way.
go into BIOS, and try something mild like 3.0 GHz. or set FSB to 1333 and see. that should work fine with none, to very little vcore raise.
