    Piker Alpha's ssdtPRGen script will generate a SSDT you can use to achieve the maximum amount of power states for your desktop CPU. Please note that desktop power management is not mandatory.

    Requirements:
    Working internet connection

    How to Generate a SSDT for Power Management

    1. Configure system with appropriate SMBIOS for your CPU using Clover Configurator

    2. Open Terminal and download Piker Alpha's ssdtPRGen.sh

    Code (Text):
    curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh
    3. That will download ssdtPRGen.sh to your user directory. The next step is to change the file mode (+x) with:

    Code (Text):
    chmod +x ~/ssdtPRGen.sh
    4. For default SSDT generation, type:

    Code (Text):
    sudo ~/ssdtPRGen.sh
    5. Type n, n

    6. Open Finder and in menubar choose Go/Go to Folder...

    7. Type ~/Library/ssdtPRGen/

    8. Mount EFI using EFI Mounter v3

    9. Copy SSDT.aml to /Volumes/EFI/EFI/CLOVER/ACPI/patched/

    NOTE: The Power Management SSDT should always be SSDT.aml. If you have an SSDT.aml there already, rename it SSDT-1.aml, etc...

    10. Reboot


    How to Test Power Management

    1. Download and compile AppleIntelInfo.kext using XCode. Or download here: View attachment AppleIntelInfo.kext.zip .

    2. Drag AppleIntelInfo.kext to desktop

    3. Open Terminal

    4. Type:

    Code (Text):
    sudo -s
    5. Type:

    Code (Text):
    chown -R 0:0 ~/Desktop/AppleIntelInfo.kext
    6. Type:

    Code (Text):
    chmod -R 755 ~/Desktop/AppleIntelInfo.kext
    7. Type:

    Code (Text):
    kextload ~/Desktop/AppleIntelInfo.kext
    8. Type:

    Code (Text):
    cat /tmp/AppleIntelInfo.dat
    The amount of power states will then show in the Terminal window.

    Perfect, yesterday, I tried it by following the "old" guide, can anyone please check my result?

    details (logs, terminal logs etc.) are in this post: http://www.tonymacx86.com/mavericks...cpu-igpu-power-management-86.html#post1142796

    And I do not know, but I think that turbo mode wont start

    How does the SSDT need to be referred to in the config.plist file?

    Firs of all thanks
    Second, what is the benefit?
    Third I just generated ssdt.aml and ssdt-1.aml and put them in the patched folder with DSDT.
    I got one error, it said Board-ID doesn't support ivy bridge but I generated anyway.
    Here is the test result I hope I did correct.

    The benefits are that the are more states, so if your desktop is idle it will be at 16 (1.6GHz) or when your rendering a video it will be at 37(3.7GHz) if you did not generate an SSDT it would be stuck at one state.

    "Error: Unknown processor model" on my i5-6600k. I guess this hasn't been updated for Skylake yet?
