    It´s really nice if enabled in BIOS. The dropdown menus in the processor power plan pressing "revealed" in the first post here are now working fine. Give it a try :)

    Yep I have just been tinkering with those with HWinfo64 running in the background, you can see the processor basically sat at 3.5ghz with the energy performance preference at 0%
    I left it at 50%

    Right, that was my experience, too. For the power plan on battery I put it to 60, I think. Don´t know if it was much of an improvement. But it´s fine to get it integrated in the system without having to use additional Software. I for myself have to wait till we get to know the variables for the 9560.

    I know that this is little bit faster that i promised :-D But just accidentally found all needed tools around in my lappy (i thought i moved them already somewhere), so there is info for 9560

    Code:
    0x3F50B             Setting: Intel(R) Speed Shift Technology, Variable: 0x4BC {05 91 B6 01 B7 01 D3 01 01 00 BC 04 10 10 00 01 00}
    0x3F51C                 Option: Disabled, Value: 0x0 {09 07 04 00 30 00 00}
    0x3F523                 Option: Enabled, Value: 0x1 {09 07 03 00 00 00 01}
    
    So, your variable offset will be 0x4BC and value to enable as usual 0x1 (0x0 to disable - in any case)

    GoNz0 confirmed that EPP of 50% and 65% allow his 9550 i7 CPU to hit max speeds

    Rockstar - can you confirm if EPP of 50% allows your 9560 CPU to hit max speeds?

    __________
    Not an XPS but a new Kaby Lake CPU....

    Uncle Web recently posted that his Kaby Lake CPU speed was capped unless EPP was below 80 (80 of 255) or below 30%. You will need to check your CPU but that implies you can reach max CPU speed with EPP only in these ranges:

    0%~30% (on 100% EPP scale)
    0-80 (on 255 point EPP scale)

    [EDIT] See below:

    Do you mean 50% and 65%? Or are those on confusing 255 scale?

    Is that on your 9550 (I know answer)?
