Windows 7 ram problem

[rmelhorn]

I just installed Windows 7 64bit. I have 4 sticks of G Skill pc2-6400 800 ram. I had to remove 2 sticks to install Windows 7. When I add the other two sticks, computer will not boot. I swapped out the 2 sticks that worked with the other two that I removed and all memory works when I only have 2 sticks installed. Bios is set to default. Asus m2n32 sli mb...phenom. Any ideas?
