2. On P35 boards using the Q6600 multiplier 6, 7, 8 & 9 are available, but on this board even when I select multiplier 6-9, it always defaults to 9. I take it the multiplier can't be changed when using the P5W DH with the Q6600?
I see this presently on the Commando 1404 BIOS too but for that mobo, it is a misreporting of speed on POST. The set multiplier actually works as can be seen using CPU-Z in Windows.

Anyway, do give 9 x 356FSB a try if you are still going for 3.2GHz. I am not sure if the P5W can do 400FSB with quads. Haven't had the chance to try it out yet with my SLACR, still testing it on my Commando.
