I have a P5n32 E SLI, and Man its a weird MoBo! Cant OC past 2.88 on a q6600, others get less, though a few get more! Damn thing isnt even stable at 333!! For me, at about 317 onward, the thing freezes at post. At 1485 FSB and other mods, I can get into windows, but it appears to have lots of FSB holes! (Not stable anyways!) Let me know how it goes for you!!
