Hi, I am running an Asus A8V deluxe motherboard and i previously had 2 512mb sticks of geil ddr400 ram in. I decided to add 2 more sticks of the same mb/speed only kingston brand. The only problem is my computer is not detecting the ram at all. Post Bios message says only 1024mb is detected and my system info only says 1GB detected while i'm in windows. Any clues to what is going wrong?
