Gigabyte GA-P35-DS3L ram question

[ne0-reloaded]

I just bought this motherboard and 2x2gb sticks of ddr2 667 memory. For some reason I can't get a video signal. I swapped video cards and the only thing connected now is the motherboard, cpu, and video card. The mobo supports ddr 1066 and I assumed the fsb would just be underclocked. Do I need faster memory or could something else be the problem?

Thanks

specs:
ga-p35-ds3l
c2d e6550
2x2gb patriot ddr2 667
radeon x1300

edit: found the problem. didnt connect the 2nd 12v connector to the mobo
