Well there's talk about how vdroop is kind of a safety measure and surely any electronic engineer could completely eliminate the phenomenon.

By the way, I was never close to 3.9ghz before, but I think I might be able to make it happen now... I think at 70mhz increase is going to be pretty easy though.

EDIT and I really hate to go off-topic, but what is a good/safe max FSB, NB, and SB voltage? I'm afriad to go over 1.325 on FSB because I don't know what it does, I'm afraid to go over 1.45 on NB because I know what it can do, and I'm afriad to go over 1.6 on SB because I don't know why to do it.
