>Sorry but like to jump in here Craig. What happens to the extra 1GB, mine too has 4GB but Windows XP says 3.50GB RAM. Are other apps / utilities able to use this extra RAM? Can we make Windows move the PageFile onto the extra memory (by adding lots more) onto a RAM Drive if it can use beyond that 3/3.5GB RAM?
