I just built a system around this motherboard, and I put 2 gigs (512 x 4) of Geil Golden Dragon ram, and the system only reports 1.5 gigs of ram. I checked each chip in slot 1 and they registered OK, then I placed one chip in all four slots and it always registered regardless of slot, but when I place all four chips in the system, I still get a report of 1.5 gigs. Am I missing something? Any clues? Thanks.
