    Hi All

    I am really confused. I have Windows Vista 64 bit Edition, which
    have installed SP1 on. I have 4gb of Ram, which is correctly shown i
    the System Information (this is also shown as 4gb in my 32bit Vista OS)

    But here is the problem, in the Perfomance tab of Task Manager it show
    that I only have 3070MB of Physical Memory. In the Resource Monito
    confirms this

    My motherboard supports 8gb ram, and I am using Crucial memory, th
    model of which is supported by the motherboard

    Does anybody know why this might be, and how I can resolve this issue

    Thank

    TP5harp

    You might have to turn on Memory Remapping in your bios if you have th
    option
    'The system memory that is reported in the System Information dialo
    box in Windows Vista is less than you expect if 4 GB of RAM i
    installed' (http://support.microsoft.com/kb/929605

    First thing to do is to see if your BIOS supports more than 4GB of memory. If you do
    not have the memory remapping option then either flash the Bios with the correct
    upgrade or replace it to comporting one
