    I have a AMD X2 4200 machine that only shows 1 core & 1 logical processor in
    system information. Under Device Manager it lists AMD Athlon 64 X2 Dual Core
    Processor 4200+ twice. Under task manager in performance tab only shows as
    one CPU, under view - cpu history I only have one option "one graph per CPU"
    , CPU-Z shows as dual core 4200+ but will not let me select 2nd processor.
    This leads me to beleive that Vista RC2 is turning off or not recognizing the
    other core. I have Vista on its own partion and dual boot with winxp sp2 and
    everything shows up as dual processor under winxp sp2. I have tried right
    clicking on processes and see nothing about affinity. Any ideas or help on
    this would be most welcome.

    Does the BIOS and Devidc Manager show both CPUs show as enabled?

    Yes the BIOS (newest Award) sees the AMD X2 4200+ Dual Core Processor and
    device manager under processors shows "This device is working properly" as
    "AMD K8 Processor" under properties for both listings of the AMD Athlon 64 X2
    Dual Core Processor 4200+. Also I have loaded in the AMD 64 Optimizer driver
    from the AMD web site in hopes of getting Vista to see Dual Core to no avail.

    Hi! I have the same processor as yours. I think it is ok if, under device
    managers, processor is listed twice.

    BTW, can you tell what motherboard you get? Mine is an Asus M2R32-MVP. I
    have some problem with Vista. I can install OS without a glitch but after
    some restarts, my HD spins forever. I am suspecting a chipset driver problem
    (ATI xpresss 3200).
