@Crusty: ALL dead links there... The links that aren't entirely dead show the FBI warning because they go to Megaupload.
@Mafio: 6GHz was easy, I'm hitting in the mid 6GHz range, which was also not bad to get to... Around that point things whig out, and it seems to be the board and not the CPU.
@Turrican: I've heard others say that too. I don't have either of the other boards you suggested, so I'm just trying to do what I can with what I have.
It looks like Booon got to the mid 7GHz, if his submissions are accurate:
One of those says foxconn blackops (cpuz), the rest all say Rampage Extreme.
Probably going to screw around more with the p4 651 tonight and see if I can get it further. http://hwbot.org/search/submissions/....g.&cpuId=1046
