I had been wondering about that and asking around if my P35 board would limit my overclocking with the Q9550. I almost picked up a P45 board, but I got the impression it wouldn't make a difference.

I have a vdroop of about 0.06 to 0.07. So my 1.36 in the BIOS drops to about 1.30 with occasional dips to 1.29 under Prime95 Small FFTs.

Is the vdroop on the P45 boards less?
