    dual core cpu and only one core working? or is it


    I have installed windows 8 x64 consumer preview. Under the task manager performance, Im only seeing one cpu graph, and it reports one physical processor and two `logical` processors.

    Also under device manager, when I get the properties for `Computer` it says acpi x64 based pc, I think older windows already reported multi processor unless the wrong HAL was installed.

    In device manager under processors, properties shows to separate entries of amd 550.

    My concern is if the wrong HAL was installed.

    Can someone help me with this?

    Right click the graph in Task Manger, select change graph and click Logical Processors. HTH.

    So logical processors is trhe same as cors? And theres only one HAL for windows8 (maybe 7 too?)

    As I understand it, Physical Processors is how many processors you have in your computer. Say if you have a Dual CPU board with two Intel i7 Processors, You would have two physical processors.

    Or I could be remembering that wrong and Physical Cores is how many cores you have and Logical Cores is how many cores you have with HyperThreading. In that case, you would have a single core CPU with support for HyperThreading.

    No I have a 550 be it states its a dual core,I was just curious about the HAL

    my core2duo also says ACPI x-64 based PC so don't worry and it is 1 physical and 2 logical processors

    Thanks I guess I can just assume windows 8, and maybe also windows 7, have just the one HAL.

    multicore platforms are "target" for both win7 and 8, leaving single core as a "supported platform".
    also even just announced 8-core i7extreme fits in "normal" acpi spec, so there's no need for uncommon configuration.

    if u still need to make sure about it, run some application, that is resource consuming but uses only one core (some rar/zip archivers have options for that, or video rendering etc) - you will find that it takes only 50% of total processor power.

    plus, as somebody said earlier, on a cpu usage graph, right-click, change graph to -> logical processors
    u will see graph for every core (HT and other similar technologies won't get separate graph)
