  1. Hi

    I have Dell Dimension 8400 and recently replaced 2 x 512 MB cards with 2 x 2GB cards. When I ran the systyem specification program it only shows that I have 3GB
    of RAM.

    Anybody know why the total 4GB of RAM is not recognized.

    You probably have a 32 bit operating system and that is about the limit that a 32 bit OS will recognize. If you want more RAM recognized, you will need a 64 bit OS.
