    So I recently upgraded the memory in my PC from 2GB to 4 GB of RAM (4
    x 1 GB single channel DDR 400). Now the problem arrives - the BIOS
    can only see 3 GB. Additionally, Vista (64 bit) Ultimate can only see
    3GB (under "System Information").

    My first thought was that one of the DIMMs was bad, so I checked each
    DIMM separately and rebooted my machine with only 2GB at at time.
    Each memory permutation posted correctly and was recognized correctly
    in both BIOS and Vista.

    Next, I thought an updated BIOS could do the trick. I have a LANPARTY
    UT nF4 SLI-D, so I checked the product page on DFI's website (http://
    us.dfi.com.tw/Product/xx_product_spec_details_r_us.jsp?
    PRODUCT_ID=3469&CATEGORY_TYPE=LP&SITE=US). Under the BIOS section, I
    saw several updates of which I decided the version dated 2006/04/06
    would be the best choice for me. I tried using WinFlash, but I keep
    getting an error that: "OnBoard BIOS not Award BIOS !". This error is
    not valid as I verified my BIOS version inside of BIOS. Since I don't
    have a floppy drive, I burned the BIOS files to a bootable CD and
    tried to flash the BIOS the old fashioned way. The system recognized
    the bootable CD, but just froze at the "Boot from CD:" screen. Either
    way, none of the features listed from my version (2005/06/23) to the
    newest version (2006/04/06) appear to address any memory issues.

    The weirdest part of the whole scenario is that SiSoft's Sandra Lite
    (http://www.sisoftware.co.uk/index.html?
    dir=dload&location=sware_dl_3264&langx=en&a=) can recognize all 4GBs
    in Vista.

    System Setup:
    AMD Opteron 170 Denmark 2.0GHz Socket 939 Dual Core Processor
    LANPARTY UT nF4 SLI-D Motherboard
    4 x 1GB DDR 400 (single channel) DIMMs
    2 x GeForce 7900GS 256MB GDDR3 PCI Express x16
    Microsoft Vista Ultimate 64 bit

    Any and all input is appreciated.

    FYI . . . Microsoft Lists Vista 64's memory limit to over 128GB and
    DFI lists the motherboard memory limit at 4GB.

    Sounds like a hardware problem of some kind and if the BIOS only recognises
    3GB then you have little chance of Vista seeing any more than that. I had a
    similar problem with 2 sticks of 2GB RAM. Each on its own would install as
    2GB but together they would only give a total of 2GB. Replacing one of the
    sticks solved the problem.

    There is a great article at http://www.dansdata.com/askdan00015.htm
    which explains many of the issues with 4GB memory with 32 and 64 bit
    windows in different hardware configurations. I believe my particular
    problem will only be solved with a memory remapping feature available
    in BIOS.
