    I am running the 64 Bit RC of Windows 7, and am having an issue...
    My Athlon 64 X2 is seen by the system as a dual core CPU, but the system only seems to use 1 core...
    CPUz shows it also as a dual core, and at the bottom for Processor 1 it shows 1 core and 1 processor...
    Task Manager and resource monitor only show 1 CPU graph as well...
    I have done both an upgrade from Vista Ultimate and a clean install, downloaded all updates etc.
    Both have the same issues...
    Vista Ultimate 64, Ubuntu Linux 9.04 and XP Pro all see both cores and utilize them.
    I have set power management to performance and set CPU power management to passive and still no go.
    Any and all assistance appreciated.
    Thank You,
    Dave

    New Info...
    Device manager, under Computer shows "ACPI x64 based PC"
    I cannot find halmps.dll for multiprocessor support.
    Where can I download this file?
