I'm putting together a system for my brother's Christmas present. I bought an A7N266-VM, xp1700, 2 sticks of 256 MB DDR RAM from Crucial, a 40GB Seagate HD, and Windows XP Home. Everything seemed fine until I noticed that only 480 MBs of RAM is diplayed under Control Panels -> System. I tried swaping out a stick, but found that regardless of which stick I swap out, only 224 MBs of RAM shows up. Is this a mobo problem or something else? Any suggestions would be appreciated.
