    I've tried this before, it does not work, the system restarts and prior to loading up the Windows loading page it BSOD's.

    I've tried various combinations. I first need to install 4GB, shut down the PC then install the additional 2GB for the PC to boot up without any issues.

    most likely it is the hardware limitation of your motherboard. most older boards only support 2-3 GB of ram

    This motherboards limitation is 8GB, PC is only a year old.

    SO I enabled the memory hole within the BIOS, installed the latest Nvidia driver 190.62 (DirectX ver 11.0)....same thing.

    In System Properties: 6GB installed (3GB usable) 64bit

    Resource Monitor under Physical memory shows the following:

    Available: 1984 MB
    Cached: 1954 MB
    Total: 3070 MB
    Installed: 6144 MB



    Hardware Reserved: 3074 MB
    In Use: 1061 MB
    Modified: 64 MB
    Standby: 1912 MB
    Free: 56 MB

    on my bios its under advanced chipset config. and disable uma to disable the integrated graphics

    i have 4gb of ram and it said 3.75 usable with 5.9 memory rating in WEI. I disabled the integrated graphics and now it just says 4.00 GB and the memory rating went up to 7.2

    It is deactivated by default, shows 0 MB.

    BTW, My BIOS is not overclockable in any way.

    Hoi !

    Same problem here: 64-bits Vista 7 RTM, uses only 3,25 Gig from the 6 Gig's.
    On the same PC is Vista Ultimate 64-bits installed, and Vista just uses the full 6 Gig's !

    So I think it can't be a hardware-problem.

    When I look with Everest at my modded bios (HP-slic), I see also the following string:

    MCFG: Memory Mapped Configuration Space Base Address Description Table

    TabelbeschrijvingMemory Mapped Configuration Space Base Address Description Table
    GeheugenadresCFEE9C80h
    Tabellengte60 bytes
    OEM IDHPQOEM
    OEM Table IDGBTUACPI
    OEM Revision42302E31h
    Creator IDGBTU
    Creator Revision01010101h

    So my question is: could this be the reason of this problem ?

    Greetz,

    Harry.

    Well, looking further into this issue, I've realized that many users are reporting similar problems with how many GBytes of memory are actually being used from the total installed. If I ever come up with a solution I will post my results.

    Solution to the issue

    Goto Msconfig

    Boot->Advanced Options

    Just check the status of Maximum Memory
    If it is enabled, disable and re-enable to support your maximum memory.

    After the maximum RAM has been activated in the system again come back and disable the check.

    I had 8GB DDR2 installed on my laptop and for this reason only it was showing 2.96GB usable.

    Your motherboard can only address up to 4 GB of memory, and you probably have 1 GB reserved for the onboard video I bet, leaving you with 3 GB. It looks like you separately installed a 8800 GT so disable the motherboard on-board video.

    I am not having any issues with my intall of win 7 x64 Ulimate. I have 6 gigs of DDR3 on a I7 920. Reports 6 gigs and thats it.

    I would say it has something to do with onboard things like video, sound, etc. reserving space.

    In this context 'LFB' describes dedicated RAM for the onboard graphic.

    If the onboard graphic is disabled then the framebuffer is not needed either.

    Standalone GFX cards have their own frame buffers. (A.K.A. RAM/Memory.)
