XP uses only one of the cores?

    Just read in another post that xp runs only one of the cores, not both? How can we confirm this? I did look at properties of the system and it does show the core duo but I'm not sure how to confirm that XP is using both cores.

    Any ideas?

    right click the task bar
    choose task manager
    click the performance tab
    you should see 2 cpu graphs iirc

    Hmm... Did the old hack (pre-Boot Camp) support both cores? I remember hearing about Duos being cut back to Singles.

    the retina of the mind's eye
    it uses both cores

    run taskmgr.exe (or hit ctrl+alt+del) to pull up the task manager.

    click the Performance tab and you will see graphs for both cores. The CoreDuo is not a hyperthreading processor, so there is no 'logical' 2nd processor


    CPU-Z accurately reports this

    Core Duo confirmed

    Indeed, I see two graphs. Hope I didn't cause anyone alarm.

    That is good news to hear- not that I have an intel Mac yet...but when I do, it will be nice to have XPee use all of the available processing power. :)

    FYI - it uses cores based upon power management. If you make your battery icon appear all the time (plugged in or not), you'll always have an icon that you can left click to select the mode. I believe "always on" makes both cores go active or you can set to "portable" and have only one.
