Been struggling with this board for the last hour or so. I can get 525FSB to post with my golden E8600 but anything above that is an instant crash. Can you guys doing 600FSB tell me the following?
CPU/MCH Skews?
FSB holes?(I think 400-433 is bugged, never boots for me)
MCH Latch used? 333MHz is proving to be far more stable than 400MHz
Performance Enhance used? Turbo(default) works better than Disabled or Extreme

I'm using 6x multi and the following volts on the QX9650 cooler. This CPU was doing 600+FSB with the EP45T-Extreme on air and the memory does DDR2-1240 CAS4 so I assume it must be the board.

vCore: 1.30v
vMCH: 1.50v
vDIMM: 2.10v
