    It will. Look where it says "logical processors," and you'll see there are 8. This is just how the AMD architecture presents itself physically to Windows.

    On your Task Manager Performance Screen at the bottom check on Open Resource Monitor and then CPU tab and you should see all your cores and activity.

    And when I installed windows 8 my cores were turned off too. I went into my the bios for my ASUS 990fx sabertooth and there is an option called core unlocker that allows you to manually activate them. Also go to the power mgt settings in windows 8. Go to advanced. Then show/ adjust hidden settings. Then Change the power settings to Max performance.

    The core unlocker as nothing to do with your FX-8130, this is used for peoples with 3 cores CPU to unlock the 4th one, sometime it work, other time not. On a FX-8130, they are no lock ( hidden) cores.

    Aside if all your 8 cores was turnoff, your PC will not even boot. You do have a BIOS option to turn on and off some cores ( activate) , by default in an Asus BIOS they are all turn on ( enable) and you can't turn off the 1 and 2, here a picture of a Crosshair, this page is on default the Saber is about the same.

    Please don't play with this BIOS setting page, this is only to achieve higher OC, as the less cores you have running the higher you can OC, unless you have liquid nitrogen, it's useless to do it

    That's very nice, any idea what parked means? It usually says that for all cores after the 4th. I presume it means it just inactive because it isn't needed.

    I may do the power option!

    A parked core is turned off until needed. This is a power saving feature when all the cores are not needed. Under Power Options the Balanced Option will turn on the Parked feature. The High Performance Option will turn off the Parked feature.

    It's probably allready explained above, forgive this small addition:
    It's a misunderstanding: the CPU is a quad-core with hyperthreading, don't know how AMD calls that because I have Intel but it's the same: your core number doubles with the logical processor count make it 4x2=8.

    You have 8 logical processors, that's what you need to know.

    A zoom of the thread starter's screenshot:
    Click image for larger version
    So the initial screenshot says it all, you just need to know a bit the details.

    Everything's OK.

    You can right click on the processor graph in task manager and choose "show logical processors".
    You should see all 8 of the graphs.
