I am having the exact same problems as Tiarmisu with the same components; e6600, 2x1gb 8500 tracers, ocz gamexstreme 600w psu. I flashed to 311 on first boot, and then the problems started. I finally cleared cmos and booted with one stick, set timings and voltage and saved. Put the second stick in ran 20 passes of memtest overnight and no problems. Decided to install windows so I rebooted and got the black screen again. Im at a loss.
