After playing with an E0 E8400 and various BIOS I am starting to think this board is not all it could be It actually seems happiest with ol' 1103 unmodified with E0, whereas it killed with the Ket's m1306/E7200 M0 setup

When it is playing nice E0 is fast as hell... then sporadically it doesn't want to boot at times.

If I decide to keep the 4Ghz E7200 I've been blessed with I will get another P45 board, roll the dice, and RMA this P5Q-E. The one I have is just not as consistent as all my other ASUS boards have been.
