    if you want to be able to "use" the full 8gig you need to have a 64bit
    version of VIsta, as 32 bit can only use around 3.5gb max,

    It will be unstable, so i know what to do

    Hmm well 64 bit is a problem, cause lots of game are 32 bit

    I love to play games, so ill have to wait till they ganna make game fo
    64 bit

    you could always dual boot with vista 64 as well, if you use anythin
    that would take advantage of the whole 8gigs - video editing, photosho

    64-bit Windows is compatible with 32-bit applications.

  6. You need the 64 Bit version of Windows to utilise anything over 4GB RAM. The
    32 Bit windows Vista can only use a maximum of 4GB and then, in most cases,
    it will only register 3.5GB

    All my 32-bit applications (including games) work fine on my 64-bit Vista

  8. Sorry to say that you wasted your money. All 32-bit client versions of
    Windows (not just Vista) have a 4GB address space. That's the
    theoretical upper limit beyond which you can not go.

    But you can't use the entire 4GB of address space. Even though you
    have a 4GB address space, you can only use *around* 3.1GB of RAM.
    That's because some of that space is used by hardware and is not
    available to the operating system and applications. The amount you can
    use varies, depending on what hardware you have installed, but can
    range from as little as 2GB to as much as 3.5GB. It's usually around

    Note that the hardware is using the address *space*, not the actual
    RAM itself. The rest of the RAM goes unused because there is no
    address space to map it too.

    By the way, what makes you think that having that much RAM would do
    anything for you anyway? How much RAM you need for good performance is
    *not* a one-size-fits-all situation. You get good performance if the
    amount of RAM you have keeps you from using the page file, and that
    depends on what apps you run. Most people running a typical range of
    business applications under Vista find that somewhere around 2GB works
    well, others need a little more. Some people, particularly those doing
    things like editing large photographic images, can see a performance
    boost by adding even more than 2GB, but more than 2-3GB is a waste for
    most people.

    If you have a 64-bit processor, and you changed to 64-bit Vista, it
    would see all your RAM, but my guess is that you would still see no
    improvement in performance.

    Vista 64 Bit also works with DOS apps and games if you use DosBox.

    I was wondering when someone would mention that he needed a 64-bit
    processor. I was just about to ask the OP when I came to the last post in
    the thread, which was yours.

    Like others have said, a 32-bit OS can only address 4GB, by the time other
    hardware is taken into account it'll be less than that. Detailed explantion
    up here:

    If you've got the retail version of Windows Vista Ultimate, one of the discs
    in the case will be the 64-bit version. So you could at least install it to
    try it out and make sure everything is working for you.

    Hi... I.m a gamer too and using Vista Home Premium x64 with no problem at
    all. All games play perfectly.

    Even so game like crysis are 64 bits.

    Do they even sell non-64-bit CPUs any more??

    The only "solution" i found is WORKAROUND using usb-sticks whixh support up
    to the max u can get on usb stick, that is not really ram but cooperates
    with it sort if cache-like(windows ready boost) which helped a lot on my
    systemtem as i have a graphic card eating the 2 gig i have installed,
    making it possible to usw more than the on-board mem whixh is eaten by my
    graphics adaptor.. aint the best but probably the only way to usw more than 3
    gig for RAM.. hope iz helpful for u

    32-bit OS's have a limit of 4gb ram...that's a complete address
    limitation...anything more than 4 gigs of ram requires higher addressing
    space....4 gigs is the limit.

    Phisyical Address Extension doesn't always fact, 9 times out of 10
    it yields you nothing.

    The fact you're only seeing 3 gigs of ram would indicate there's additional
    addressing issues in your computer. My laptop has 2x2048mb modules...but i
    only can get 2.96gb of ram to windows because of funky video addressing

    the "speedboost" feature that uses USB sticks as cache is useless with more
    than 2gb of physical ram, sure, vista will use it, but however it won't
    actually take advantage of it like it will with < 2gb physical ram.

    If you want more than the amount of ram you've got *NEED NEED NEED
    NEED NEED* to use a 64-bit ABSOLUTELY CANNOT achieve 8gb of ram
    with a 32-bit OS....P-E-R-I-O-D!

    I have an Alienware Area 51 m9750 laptop. I have 2GB of RAM installed on it
    and planning to upgrade to 4GB of RAM. My system has a 32bit Vista Home
    Premium installed on it and yes I know that the 32bit OS does not recognize
    4GB of RAM and so I want to try out 64bit Vista Home Premium.

    I heard somewhere that Microsoft is providing free upgrades to 64bit Vista
    for all users of 32bit vista. is it true ? if its not, then what are the ways
    that i can upgrade my OS to a 64bit version ?

    Thank you.

    Thank you Ken! You apparently have the right answer! Not even Intel support
    knows this and I've been tearing my hair out for a week!

    I happen to be running Windows Vista 64-bit and Windows will not boot-up
    with 4 gigabytes of RAM either, just like in the 32-bit version!

    My motherboard supports 8 gig only in the slower MHZ speeds, but above 800
    MHZ, the max is supposed to be 4 gig, but even that cannot be achieved.

    Your 3.1 gigabyte RAM figure is right on the money! Perhaps if I bought 512
    meg, I could squeeze out another .5 gig in the 4th slot but it just isn't
    worth it to me.

    The extra gigabyte really worked for me though because I was using 70% of my
    resources when I engaged my ATI Tuner Card through Windows Media Center. Now
    I'm running at a sweet 46% - 58% with everything engaged at the same time.

    I'm saving my extra 1-gig memory stick though. It's good to have around AND
    it was on sale!!! LOL.

    Thanks for having the correct answer.

    i dont think u can use 8G at the mo, but u could upgrade to 64bit, i think
    they do some kind of deal.
