Dell Dimension 8400 - Media Center 4GB RAM??

    I had 2GB of RAM installed and recently put another 2 in. The BIOS on the
    machine reports 4GB, windows shows 3GB. I found some articles about using a
    /PAE switch and a /3GB switch in the boot.ini but neither have had any
    effect. (I have tried each of these switches and both of them).

    Is there a way to force Windows to see the 4GB or should I return 1GB and
    scrap the project?

    OK, first question is does the MB show you have 4GB installed?

    You might have already seen this article -

    Another crazy thing is that Windows will only see 4GB of memory period.
    This includes the pagefile. If the MB does see your 4GB, try disabling your
    pagefile temporarily, reboot and see if XP shows all of your RAM.

    Why did you install 4GB of Ram. MS only reccomends 512MB for MCE if you are
    using an HDTV tuner which is probably the largest memory consumer in MCE.
    Is the reason you want more RAM becaue you are doing video editing or
    conversion of high resolution video files?

    Thanks for the tip on the pagefile, I will try that. I had already seen the
    article you mentioned though and neither switch there helped. I had a
    question for you..what is the MB? If you mean machine bios, then yes the
    bios reports all 4 GB.

    You do realize that this is a forum to ANSWER questions, right? Why on earth
    are you asking me why i have 4GB RAM? Cause I want it that is why, i edit
    videos and like speed...who goes by Microsoft's guidelines anyway. Next time
    please either help with an answer or just don't post.

  7. 32-bit Windows XP cannot handle more than 3GB RAM - the 32-bit address
    space is 4GB, and some address space has to be reserved to I/O registers
    and OS components.

    Windows XP x64 can handle 4GB RAM, but there is no MCE version of it. Also,
    32-bit Windows Vista at least reports 4GB RAM, but I'm not sure if it can
    actually utilize that fully.

    To fully utilize 4GB RAM or more, you really need a 64-bit operating

    I just call the motherboard, MB. Sorry about that.

    From what I've seen, XP can only handle up to 4GB of total memory. This
    includes physical and logical (RAM, Pagefile). Some ideas I've seen were to
    disable the pagefile, and after a reboot, see if Windows shows your full 4GB
    of physical memory. If it does, then you know XP is using your 4GB of RAM.
    Then of course enable your pagefile.

    I am assuming XP is using it, it just doesn't have the ability to display
    that it is using it. Let me know if this works.

    The following changes have been made to BIOS rev A05 to create A06: 05/18/2005

    1. Fix hang condition during POST with fibre channel adapters.
    2. Improve processor reporting in BIOS SETUP.
    3. Improve support for 64-bit operating systems.
    4. Updated SMBIOS structures for 2.3.4 compliance.
    5. Add support for newer processors.
    6. Fix video initialization search routine.
    7. Prevent false NMI error for some add in cards.
    8. Improve memory information reporting.
    9. Fix various USB problems.
    10. Fix keystroke for password entry in setup

  10. That appears to be wrong. I have 4GB in my machine. MCE 2005 reports 3GB
    physical memory, and I configured a 2GB page file. Task Manager says I have
    a Commit Charge Limit of 5078316KB, which is about 4959MB (it also says:
    Commit Charge: 212M / 4959M in the status bar). DXDIAG reports Page file:
    217MB used, 4741MB available, which sums up to 4958MB.

    So Windows XP apparently _can_ handle a total of more than 4GB of RAM +

  12. No. The only 64-bit client operating system Microsoft has released so far
    is Windows XP x64 Edition, which is on the same functional level as Windows
    XP Professional, i.e. it does not have the Media Center feature.

    The first 64-bit Media Center operating system product will be certain
    editions of Windows Vista. But that is not functioning in the currently
    available prerelease builds.

    So for now, MCE is only available in a 32-bit version.

    Thanks for pointing that out to me Robert.

    However, doesn't your statement below about having 4GB of RAM contradict
    with your earlier post?"32-bit Windows XP cannot handle more than 3GB RAM - the 32-bit address
    space is 4GB, and some address space has to be reserved to I/O registers
    and OS components."
    I am not trying to cause any controversy. I just want to make sure I'm on
    the right page along with everybody else so we can better help the community.

    Also, here is a pretty good link about the 4GB limit -

    Thanks for the info maybe I should look into a 64bit operating system.
    Scottyooo, Nov 24, 2005
  15. No, it doesn't. Note the term "RAM" versus "memory". More specifically,
    that's _physical RAM_ (i.e. the modules sitting in the DIMM slots on the
    motherboard) versus _virtual memory_ (which is the memory backed by storage
    in a file on the harddisk).
    Note this part:

    | In the 32-bit Windows world, each application has its own virtual 4GB
    | memory space. (This means that each application functions as if it has
    | a flat 4GB of memory, and the system's memory manager keeps track of
    | memory mapping, which applications are using which memory, page file
    | management, and so on.)

    And so it becomes clear how you can have more than 4GB _virtual memory_:
    While each process (application) is limited to 4GB address space (and
    access to 2 or 3GB application memory), you can have _several_ processes
    running, each of which has a 4GB address space of its own. Of course, only
    4GB of the virtual memory can be in physical memory at any given point in
    time, and the operating system has to swap memory portions to/from harddisk
    storage to keep the needed portions in physical memory.

    I hope this clarifies things a little :)

    I think the point here is that JW should not CARE why Jamie has 4GB of RAM.
    Curious? Yes he can be curious. But his response is like So VERY VERY many
    forum posters.

    Now IMHO that sounds very like some rubes answer at the local gas station
    when you ask directions. They ask WHY you want to get there, as opposed to
    giving you the directions that you asked for.

    Now technicaly speaking the MINIMUM Recommended RAM for MCE is 512 You will
    notice that it says Minimum recomendation. Says nothing about MAXIMUM
    recomendations does it?

    So from what I can tell here JW is the one being a long eared coarse coated
    member of the equine family related to the burrow and horse that also has a
    reproduction problem.
