    ok I found these
    8baa4a8a-14c6-4451-8e8b-14bdbd197537 - Processor performance autonomous mode (Enable/Disable)
    Specify whether processors should autonomously determine their target performance state.

    36687f9e-e3a5-4dbf-b1dc-15eb381c6863 - Processor energy performance preference policy (Percent)
    Specify how much processors should favor energy savings over performance when operating in autonomous mode.

    cfeda3d0-7697-4566-a922-a9086cd49dfa - Processor autonomous activity window (Microseconds)
    Specify the time period over which to observe processor utilization when operating in autonomous mode.

    4e4450b3-6179-4e91-b8f1-5bb9938f81a1 - Processor duty cycling
    Specify whether the processor may use duty cycling.

    made the 0 it only hide Processor performance autonomous mode (Enable/Disable) none of this actual enabled SST for me in hwinfo64 which was why i didnt anyway, no such setting in my bios of the asrock z170 extreme4

    here path for balanced plan.(I exported right from that key).

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\8baa4a8a-14c6-4451-8e8b-14bdbd197537\DefaultPowerSchemeValues\381b4222-f694-41f0-9685-ff5bb260df2e]
    "AcSettingIndex"=dword:00000000
    "DcSettingIndex"=dword:00000000
    "ProvAcSettingIndex"=dword:00000001
    "ProvDcSettingIndex"=dword:00000001

    You most likely need 1607, but maybe even new ME driver too.
    Oh, don't edit that path, do it with advanced settings and then you can look at user\powerSchemes in the balanced key (or whatever plan you adjusted).
    Here path of changes made by user, below is balanced but you'll see whatever plans and key that were altered in it.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes\381b4222-f694-41f0-9685-ff5bb260df2e

    Yeah I'm dropping it too. We can only hope Asus/Asrock adds it in a bios update.

    Speedshift is now enabled by default in bios version 3007 (Asus).

    Oh boy, frequencies go from 800-4200 faster than the blink of an eye in HWinfo with SST enabled 0_0

    maybe next time do clean install for my pc I will update the bios on my board to see if it has Speedshift settings yet.

    Though I dont think it will mater to how fast it switchs since I have Speedstep off on my power plan in windows. My OCD demands I See that SST in HWinfo64 though

    Yeah it is irrelevant in your case lol. You might have to temporarily enable speed shift or balanced profile for the sake of your OCD.

    With it enabled balanced profile feels like high performance while simply browsing or using windows.

    That`s what I prefer to set up: performance plan with p-states disabled and balanced plan with p-states configured to quickly maximize in response to increasing load (performance on demand).
