Well, I don't know if Vid does much, but my E6600 with 1.3250 did 3.15 with 1.28v (1.31 in bios) and my new quad has a vid of 0.8 something (Can't check now since I fubared the bios chip) and it did 1 hour (stopped it since I wanted to see how high it would boot) of prime @ 3.2Ghz with 1.22v load (1.31 set in bios I think) I managed to boot up @ 4Ghz and get into windows with only 1.55 set in bios and this was without twicking, just set random voltage and set FSB to 400.
