hello all. i just bought a new rig and i have 4 2gb sticks of ocz ddr2 1066 memory. however.. when i put a stick in the first slot it does not work. the fans spin up and nothing shows up on the screen. help. how do i get all 4 working. do i have to underclock? or do i have to add more voltage? or maybe a bios update? when i put a stick in the second and 4th slot it seems to work and i can get to the bios fine with 4gb
