    Will x64 recognize the new processor if I, turn off my pc, remove the single
    core one and place the dual core one, boot?

  2. If your Board and BIOS supports it, that is my understanding. Yes.

    On your first boot with the new CPU your computer will run through the
    "Found New Hardware" business (finding an "ACPI Multiprocessor PC" and some
    other things) and I don't think it will actually use both cores until you
    reboot again.

    Thanks everybody for your prompt and clear replies.
    Now I'll have to speak with the different vendors here in Rio Grande and see
    how much can a dual-core uP can cost (surely 50% more than in the 1st world!)
    Now here goes another one that may have been answered elsewhere:
    Does the OS benefit of the dual-core or is it only the apps that do?
    Carlos, Aug 5, 2006
  7. Everything benefits.

    Just curious, Carlos, why you would install an x2 into a 939 instead of
    waiting until you can replace the board, memory and cpu with an AM2

    Because I can trade my old single core and pay only the difference to go up
    to dual core.
    Please remember that computing prices in Argentina are quite high and we
    have to resort to our wit, and our pocket, to make improvements.
    Carlos, Aug 5, 2006
  10. Heck, I'm looking to do the same thing. I've got a perfectly good 939 box
    that has a 3200 in it, and 2GB of RAM. It's getting a 4200+ and another GB
    of RAM and all for a LOT less money than it would cost to build a new
    system. And it will handle a good deal more with that upgrade than it does

  11. I think you will also have to change the HAL..

    Good deal. A 5000+ x2 costs about $30 more than I paid for the 3500+ I have
    now. Can you trade mine :)

    My machine isn't stressed, and I have torn the machine apart to replace the
    chipset fan for the last time (runs cool enough without it anyway) and at
    this point I can't see myself investing $250-300 in throw-aways. For about
    $700-800 I will get the 5000+ xp, a new motherboard and 4 gig memory and
    hope the next one lasts my more normal 3 years instead of the 2 years this
    one will make. I bit the bullet on the PCI-XP video card last time and it
    rates a 5.9 on the Vista graphics rating and has been more than I need.

    I wish I could!
    Prices are so high here.
    Just FYI, on the last price list I have (not updated)
    Athlon 3500+ u$s 320
    Athlon 4400+ u$s 750
    Athlon 3800+ dual core u$s 480
    See what I mean?

  15. Well, I don't have your budget, I'm afraid.

  16. Nope. BTDT. No change required.

    Yikes!!! Hope your updated prices are better now. I see the 5000+ x2 am2
    for around $325 here.
    John Barnes, Aug 6, 2006
  19. Yeah, me to. But John's rethoric is making sense, some things you have
    already invested so much in that you also cannot afford to update it - the
    Monty Python Logic: "The only thing that is worse than buying new is not
    buying new."

    The steady march of technology is overtaking your perfectly good old
    machine, buying a new one will leave the other sitting doing nothing.
    Updating may not be a whole lot cheaper and you will not get the full
    technological effect, but at least you can have the satisfaction of saving
    some resources, on the other hand buying new and having the full effect
    isn't a whole lot more costly but having the old one sitting there, or
    having to give it away, will be a waste of those resources, something that
    is often hard to forget, sadly, but if you made one bad investment it's
    often better to cut your losses there and hope for better luck next time

    I'm sitting here with a socket 754, so not much to update there, but the
    machine is in excellent shape and became obsoleted well within it's time,
    and I too am in the market for a 5000+, although 2Gig of RAM will serve me
    well(as far as I can tell), so I can easily see the dilemma. We were in the
    same boat if I had a socket 939 as well. As it is we are each in the same
    kind of boat!

    These are the options - whichever way you turn, your rear end is behind you.
    You loose money every time, anyway.

  20. Hello ,
    For x64 there is only one HAL. The update that takes place only updates
    the kernel to a mp kernel.

    From hal.inf:
    ; Standard AMD64 HAL. Although there is only one HAL, we have two install
    ; sections so that we can move from the UP kernel to the MP kernel when
    ; processors are added to the machine.

    The only other caveat to the process would be that the hal choice was not
    forced during or post setup.
    If you force the choice you are overriding the defaults so the detection
    doesn't take place.
    For example. using F5 or F7 to dictate hal choice.
    Or if you are using a custom hal.
