This is really a question about whether or not it is absolutely necessary for me to upgrade my Fedora.
I just upgraded my computer with a couple more sticks of RAM and have it up to 8G now. I duel boot so I know that Vista (64bit) recognizes my 8G, and Memtest86+ recognizes my 8G, but for some reason Fedora 9 (64bit) says it has 3.1 G RAM. Is this a problem with Fedora 9 (64bit) or is it some configuration thing I've missed?
