  1. Task manager only shows half of cores and threads


    In my PC, i have an i7 2600k, a 4 core 8 thread processor. I have all cores and hyper threading enabled, but task manager says I have 2 cores and 4 logic's processors, or 4 threads. I have already tried changing msconfig boot settings. ANY HELP WOULD BE GREATLY APPRECIATED.

    Windows 10 Task Manager only showing half my cores.

    Hi Jim, I'm Graeme, an independent adviser here to help.

    Try these steps, which may make Task Manager show the correct amount of cores:

    - Click Start and search for msconfig.

    - Select System Configuration.

    - In the Boot tab, click on Advanced Options.

    - You should see an option to set the number of cores. Change this to the correct amount, click OK then reboot.

    Hopefully Task Manager should show the correct number now. Please let me know if you need further support! Thanks!

    Task manager only shows half of cores and threads

    Why does Task Manger shows half of the cores?

    Windows 10 Pro 64-bit

    AMD FX 8320 E processor with 16 GB RAM

    In Task Manager performance tab, it shows

    CPU AMD FX-8320E Eight-Core Processor

    Cores: 4

    Logical processors: 8

    In Device Manager, it shows 8 under Processor

    What is going on?

    Thanks
