    Vista & Dual Processors

    Hello, I recently installed Vista and I found that since installing I have
    only been running at half of my total processing power because Vista won't
    use the second processor that is on my mother board.

    Does anyone know a way that I can get Vista to recognize and use both
    processors?

    I am using Vista Home Basic and both of the processors are AMD K8
    Processors. Each processor is 1.8GHz for a total of 3.6GHz

    Upgrade to a version that supports two physical CPUs. Vista Home Basic and
    Premium support one physical CPU (unlimited cores) just as XP Home did.
    Vista Business, Ultimate, and Enterprise support two physical CPUs
    (unlimited cores) just as XP Pro did.

    My PC: HpM7750N Processor, Athlon(tm) 64 X2 Dual Core Processor 5200+
    is 64 bit, bought last Tuesday and I assumed that the OS would be V.H.P. 64
    bit
    and was sorry to find that it was not. From what you are saying, I need 64
    bit Ultimate to make proper use of the power of this new computer?

    No. Only for 64bit addressing. Unless you want to use more than 4GB of
    RAM, you don't need 64 bit.

    Re: Vista & Dual Processors

    I do want 64 bit & if what Kerry says is true, I need Ultimate to use the two
    processors (Processor, Athlon(tm) 64 X2 Dual Core Processor 5200+). Is this
    correct? Do I go to the place I bought it and simply get Ultimate Dvd(s) that
    will upgrade/install everything? will nVidia, Realtek High Def Audio etc., be
    compatible?
    Do I use or give them my "Upgrade your Windows Experience" DVD that came
    with purchase? Lotsa questions, appreciate answers.

    You have one physical processor with two cores. Any 64 or 32 bit edition of
    Vista will work and recognize both cores. You would have to contact the
    manufacturer of your computer to see what their policy is on upgrading to 64
    bit Vista. With the retail versions the 64 bit media is included with some
    editions or available at a nominal cost from Microsoft. OEM versions are
    supported by the manufacturer so you have to contact then to see what their
    policy is.

    Re: Vista & Dual Processors

    All Vista versions support dual core processors as dual core.

    But only Vista Business, Enterprise and Ultimate support multiple
    *physical* CPU's.

    BUT YOU DONT HAVE TWO PROCESSORS. You have one processor with two
    cores. Not the same thing.

    You don't want 64bit. It's a driver availability nightmare.

    Fire up Windows Anytime Upgrade and do it that way. You can purchase an
    Ultimate Upgrade online. It downloads a small app which you run then
    insert your Windows Vista installation DVD (Doesn't matter which one -
    all versions are on it) and run setup whilst keeping the Anytime
    upgrade downloaded app open.

    Re: Vista & Dual Processors

    The X2 processors are supported by all versions. They are dual core, but
    on a single package. If there are more than one PHYSICAL processor, then
    you would need Ultimate.

    And 64Bit does have some driver issues, but it isn't too bad depending
    on your hardware. You can ask around and check the manufacturers
    websites to see if it is supported yet. All of my hardware was, and it
    runs like a dream.

    x64 is not necessarily a driver availability nightmare. I have my
    system set up to dual boot x32 and x64, simply because I decided to play
    with x64 to see how "bad" it really is. So far all of my hardware is
    working, with the one exception of a cheap Promise ATA 133 card. My
    Konica-Minolta printer works, epson scanner, HP external dvd writer, 3
    external hard drives.....Not a nightmare at all..... Are you running
    x64 or just repeating what you may have heard?
