I just bought a Gigabyte K8N-Pro SLI motherboard. It has 4 ram slots, 2 purple and 2 orange for dual channel. I had 2x 256mb sticks (DDR400) running in it single channel. I bought a 512mb stick (still DDR400) but no matter what combination I put the RAM in the colored slots, I can only get a max of 786mb of ram starting up. I can get 786 out of 1x 256 and 1x512 too. In some combinations its 512 and in 1 or 2 it was 256.
So 1 or more sticks of ram just gets disabled for some reason with 3 sticks. Is my motherboard incapable of using 3 ram sticks? There is no way in the bios to turn off dual channel (bios version F4).
I noticed that the 512 stick is dual side, while the 256 are single side. I dont know anything about dual or single sided ram though. Will I have to buy another $60 stick of 512 just to get my first one working?
