I recently built a new PC. EVGA X58 SLI board, i7 processor, with 3GB 1600MHz 8-8-8-24 Dominator ram. I am currently running 32bit XP and I wanted to get to 4 GB ram. I'm OCD I know.... but I think I purchased the wrong kind of ram to get to 4gigs. I will buy 64bit at a later time, but for now I would like to see 4gigs on my XP. currently reads 2.99 and even with a 4th stick of Dominator (I bought 6 total.. as I said I will get to 64bit in my own time) it still only recognizes 2.99gigs. Should I have done a different type of ram or am I just misunderstanding something?
