    to see it all ok =

    Have you installed Service Pack 1 for Windows Vista - this is an issue that
    was addressed in the Service Pack.

    Have you enabled memory remap in the BIOS? The remap
    will move the hardware addressing to the 5th GB, giving
    Vista 64 access to the full 4GB.

    The memory remap option is not available in my BIOS =\

    Can it be emulated or forced in Vista or XP?

    No, it has to be done in the BIOS.

    Try checking the web site for the motherboard manufacturer. There may be a
    BIOS update. Check your motherboard manual too - there should be a PDF
    online - for memory mapping information.

    I think there's someting more going on than just the available
    memory issue. Did anyone notice that the OP's system has a
    3.06 GHz P4 and 533MHz RAM, but only has a performance
    rating of 1. With those specs it should be in the vicinity of 4.
    My old 2.4GHz P4 with PC3200 RAM rated at 3.7.

    I think there's someting more going on than just the available
    Good catch. The OP needs to drill down and get the details of of the
    experience index to see which item is not performing.

    Or which failed to complete a performance test, Vista assumes 1.0 until
    proven otherwise.
