Dual Processor Info

    I have a Precision 650 with a 3.06 hyperthreading processor running WinXP.
    When I enable hyperthreading, Task Manager shows, in the Performance tab,
    two CPU graphs, one for each CPU.

    I also have an old Precision 610 running Win2000, which runs Windchill
    Graphics Server. To increase performance, I just added a second PIII Xeon
    processor from an unused Precision (same clock speed). How can I tell if the
    2nd processor is being used? Task Manager only shows a graph for one CPU;
    should it show 2? The BIOS setup shows two CPU id's (in the format
    673,673). Nothing in system info seems to point to the fact that it is now
    a dual processor machine.

    Then processor was added after installing Win2000; is there something I need
    to do to tell the OS?

    Any help appreciated.

  2. Yes, the OS installs specific files that allow multiprocessor function. You
    will see these on boot-up, as well as other parts of the OS. When correctly
    installed, and dual CPU computer will show two CPU charts.

    Do a little googling and you should turn up instructions on how to do it
    manually or maybe MS has a tool to do it. I last did it on NT4, so my info
    would be outdated.

    Next time you install Windows on a computer that may need a multicpu upgrade
    later, install with the multprocessor switch enabled since it works fine if
    only one is present. The additional overhead of the mp kernel is
    negligible. Then the addition of a CPU is truly a drop-in.

    It could be so simple as to check the 'one graph per cpu' option in the task
    manager options menu. With only 1 graph, if your cpu optimisation never goes
    over 50% it's fair to assume you're only using 1 cpu. You need XP Pro for 2
    cpus - I have it and it works a treat, although in theory it doesn't speed
    Pro up, it means I can do other stuff at the same time without 1 application
    bogging down another.

    Any time you do big hardware changes, it's not a bad idea to reinstall your
    os, as you get to update drivers, get rid of junk you don't use etc at the
    same time.

    Hey hey hey.. Hello
    I m looking for a precision 610 motherboard... so if u want to sell
    it, i would buy ;-)
    Actually, i think u need to reinstall your system and patch it with
    last service pack from microsoft....
    regards.

    And the correct answer is.......

    Go into Device Manager, expand the Computer button, RMB on the
    Uniprocessor icon and select Update Driver. Install from a specific
    location, do a 'Don't Search' and then select the correct type
    Multiprocessor (ACPI, etc.) DO NOT CHANGE the processor type. If it
    was ACPI Uniprocessor, select ACPI Multiprocessor. If it was MPS,
    stay with MPS.

    Click finish, and re-boot. You're done. And, man, what a difference.

    Regards

    Do you have to have a dual processor for this to work?

    I had to ask.......

  7. My understanding is this will work fine on single CPU computers as well, but
    I haven't tested it.

  8. What is the difference between MPS and ACPI?
