i got a conroe 6600 on an asus p5w dh board. i was wondering why everyone is using so much voltage when overclocking. i first oc'ed the cpu up to 2.88 @1.3375 vcore and it passed orthos for 10 hours. no other stability tests done. then i bumped up the voltage another step up to 1.350 and oc'ed the cpu to 3.2. i'm in the middle of running orhos now for two hours without a problem and i've been browsing the net while doing it. is my computer likely unstable and i just don't realize it yet or am i just the lucky one? i will do orthos for 12 hours and probably memtest for another 12 to be sure it's ok. if it does turn out alright, i might have a cpu like the one anand reviewed.
