I recently jus installed 2x 1gb sticks of ram on my cpu, when i pull up the bios and the system properties it only recognizes 1024mb not 2048mb, i inserted the sticks individually also and it only recognized 512mb for each one, im not sure if i got jipped or if im jus doin something wrong, the model #'s for the sticks of ram are (1GBUFURTULAA) and my mother board is a (MS-7061), and im running windows XP Home, i did alot of compatabillity research before i purchased the memory sticks so i know there compatible, but if someone could help me out with getting my cpu to recognize the full 2 gigs it would be greatly appreciated!!! and im not sure about my OS and the 32bit & 64bit terms, but if someone could explain those to me in laymen terms and how i could find out what mine is that would help me out alot also!!! ty!
