i actually have a similar problem to that review, i can't run 2.66 with stability for too long, especially not in games or benchmarks. my Iwill p4r533-n is a piece. i've tried all (or at least i think all) of the rdram boards, that asus is by far the best, i was just on a limited budget and the IWill was the cheapest (got what i paid for). i tried overclocking to 2.72 and my system became completely unstable. anyway, good luck with getting that asus.
