  1. Hi, I have 8 GB Ram installed on my computer. But I can only use 2 GB! I Have Windows 7 Enterprise 32-BIt
    When i right click "Computer" under "start", I click proberties and a windows pops up with some of my system information. When I go down I see:
    "Installed Memory (Ram): 8,00 GB (2,00 GB can only be used)
    And when I go to taskmanager it also says 2046 MB of ram!

    I think It has something to do with 32-Bit...
    I've read that 32-bit only can have up to 4 GB Ram and 64-bit 128 gb ram!
    But still, I can only use 2 GB Ram and i want to use 4 GB without Installaing 64-bit. Or 3 GB ram would also be great if I could get that!

    Weird, should show 3GB.

    Why not go to 64-bit, you'd be able to make use of all 8GB that way.

    Most 32-bit programs will still work. I can't think of any programs which don't, but if you do have vital 32-bit programs might be worth checking out if they'd work.

    Btw, why did you get 8GB of RAM?

    I think it depends on the video card being used, because the VRam counts in the 4 GB addressable by a 32 bit OS.

    @Unknown Stranger:

    Could you give your complete system specs? If you have a video card with over 1gb of ram that could be the problem.

    Are RAM Chips identical?

    If your RAM chips are not identical, that can cause this issue.
    You may also have bad RAM.

    What size are they 1GB 2GB or 4GB? i suspect they are 2GB, if so try 2 only and see if you get 4GB total. Then try the other pair, same test.
