Well, i'm still fiddleing with my ocing(my system specs are on the P4 2.6C won't oc post i made earlier if you need them). There are several reasons I think i can't get the 1ghz fsb out of it. First off, my PS Antec True 380 isn't bad, but when i turn the Vcore up above 1.6 it starts fluxuating ranging from 1.586 to 1.68 v. That fluxuation i think would cause the cpu to make errors and freeze. Does anybody know what PS tom uses when he does his 4 and 5 GHz cpu's??? I also am thinking of watercoolin. But who makes good coolers?? I know tom said the Corsair Hydrocool is good, I think the swiftech ones would be too, but i haven't seen any benchmarks on them. It is possible that the CPU has just plain old reached it limit, but that doesn't seem likely at 3.12 ghz because they come at 3.2 from the factory, so the core should be capeable of it. Well, if anybody has any suggestions i'd appreciate it.
