ASUS P5Q-E (P45) pre-view

[roubagalinhas]

i have a p5q-e bios 1103 + E7200 + 4GB DDR2 1000MHz+

i cant boot windows over 440FSB, it stops always @ windows loading bar
i've tried raising pll, nb, vsb, and other values without success, as well as straps
tried other bioses as well

the previous owner of this cpu guarantees it makes at least 550FSB(on P35), and this board made 500FSB @ minimum voltages with my previous E6600

any clues?
my current config is cpu @ 400*9.5 1.3v, mems 500MHz 1.8v, all board voltages @ "minimum"(first value above minimum)


thanks
