    to properly use 4gb you need 64bit

    if you want system info to simply show 4gb, install sp1

    This 4gb/32bit thing should be stickied or something because it's getting tiring. I have personally explained it 3 times in here in the last 6 months or so.

    Basically, depending on your video card and other hardware, a 32bit machine will only use approximately 3.5gb of memory, and can only address 4gb. The missing 500mb is being used to address external memory ranges (for hardware, such as your video card)

    There is no software or magic setting to fix this, it is a physical limit resulting from the fact that a 32bit number has a maximum value of 4294967295... or 4gb

    Your motherboard and BIOS have to support the remapping feature for PAE to work correctly.
