I have a Mac 3.1 and I just bought a ram upgrade of 2 2gb sticks from an authorized mac shop. When I load up Bootcamp or OSX the basic info tells me I have 4 gigs of ram. Problem is when I use task manager in windows it only shows that I'm using 2gigs. So my question is why can't windows use all of the ram and how can I tell if the same thing is happening on my Mac side. And is there a way to fix this.
