    hi all,i have just updated my processor in vista ultimate 64 from amd 64
    3200 to the amd x2 dual core 64 4200 and when i booted up for the first
    time vista says searching for new drivers to install for my new hardware
    then comes up failed for unknown device.!!!! tried searching on amd
    website and on windows update but no driver for processor . I run a dual
    boot with xp64 and vista64 when i booted ino xp it said installing new
    device then came up ok device installed . When i go to device manager in
    vista the new processor has no driver 4 it do i need to worry or just
    keep using ? seems to run ok in vista but i cant figure out why vista
    didnt recognize this processor and xp does ..:(

    Hi,

    What chipset is the motherboard using? I've seen a number of reports of this
    issue with nvidia chipsets and that processor.

    Did you upgrade the bios on the motherboard before to ensure that the CPU
    would be recognised. I have the X2 4200 on an ASUS board and no isues
    whatsoever

    no i did not update bios on motherboard. would this help? i thought tha
    if you update bios on motherboard could cause problems especially if
    download a bios update over internet

    If your currnet bios revision does not recognise your CPU, there chances are
    that it will appear as unknown both in the bios and in Vista.
    Secondly, there could well be performance implications. I'd go to your
    motherboard's website and look at CPU/BIOS compatibility tables and see if
    your current version supports your new CPU.
    There are a number of ways to flash a bios these days- over the internet is
    one of them.

    Hi,

    Just read the instructions carefully one how to update the BIOS for the
    motherboard. Asus' procedure allows for creating a backup of the original in
    case of failure, so it is a relatively safe procedure if you follow the
    steps given. You may also want to check for a chipset update to see if it
    helps.

    flashed the bios but vista still says its unkmown device? hmmm thought
    amd and microsoft worked together on vista well least they could of made
    their own drivers 4 vista or is this to much 2 ask of amd

    Hi,

    The problem isn't AMD, it's the nvidia chipset on the motherboard. Support
    for the X2 line is lacking.

  10. The chipset supports the X2 line just fine. I've built several systems on
    boards with the nforce4 chipset and X2 processors and never run into any
    problems. The DFI board the original poster has, has supported the X2 line
    from its release date.

    Does the BIOS list the processor correctly?

    Have you tried updating the drivers for the unknown device to see if Windows
    finds them?

    On the Control Panel > System screen does it show a processor name along
    with the other system information?

    yes the bios shows the processor but when i go into vista it comes up a
    the bottom of the screen searching for drivers for unknown device an
    then fails to find any drivers 4 the device.and i have the lates
    chipset driver from nvidia installed

  12. If the motherboard identifies the processor correctly then it is definitely
    something in Vista not seeing it.

    It could possibly have to do with going from a single core processor to the
    dual core, I'm not sure how Vista handles that but I know XP updated some
    other things when I went from a single core 3000 to a dual core 3800 a year
    or so back.
