If I try to install both sticks, my computer just power cycles, never getting to the bios screen. As soon as I pull a stick out and run 1 stick, it boots up perfectly. With one stick i can even OC my Q9550 to 471x8.5 on stock voltage.
I have 5 different sets of ram I have tried:
GSkill Pi 2x2gig ddr2-8800 5-5-5-15 1.8-1.9v
GSkill Black Pi 2x2gig ddr2-6400 4-4-4-12 1.8-1.9v
GSkill 2x1gig ddr2-6400 2BHZs 4-4-4-12 2.1v
Crucial Ballistixs 2x1gig ddr2-6400 double sided modules 4-4-4-12
Crucial Ballistixs 2x1gig ddr2-6400 single sided modules 4-4-4-12 2.2v
All 5 sets pas memtest. All 5 sets do the same thing. 1 stick in it runs fine. both sticks in, it power cycles.
