thanks for reply ,it's getting too complicated for me now i have multiple kit for my Ram that could be a problem for what i readed , or my CPU i guess i will have to contact intel for RMA ..also my system Processor Interconnect Speed show 25.4 GT/s something definitely not well.thanks egain..i give up now my 2 another hackintosh overclock 4.5 with 3770k are solid with Gigabyte MB but with this Asus everything is too complicated.

Why my CPU looks like that,

Maybe because your system is not X79?

I have an X79 board (GB) with I7 4930k CPU, while not running anything HWmonitor show me ideal at 1.2ghz once I'm running some rendering (Resolve) CPU is up to 4Ghz with X40 multiplier , is that mean that my hack using Controlled SpeedStep?
please see attached as well thanks

No. That is not OS X speed step. Your BIOS's MSR E2 is locked. Your system is only reaching 12 & 40 which apears to be controlled by the bios and not os x.

AFAIK, gigabyte X79 boards are all locked.

@ Shilohh
Asus P9X79 LE, Intel i7 4930K @ 4,2 (x 105), Clover in EFI (UEFI mode bios), Asus nVidia GTX 760 OC 2GB GDDR5. Everything is fine, even without X79X86PlatformPlugin.kext and with DropOEM in SSDT options (SSDT.aml generated with Pike's script and flags -c 1 -w 3 -turbo 4200). Speedsteps and Intel Power Gadget are looking really good. So my question is: what X79X86PlatformPlugin.kext and system ssdt.aml are needed for? Did you try your set up without them?
Thanks for your time

At the time of this guides writing, X79X86PlatformPlugin.kext (using the Mac mini 6,1 step context dict) allowed more lower states to be reached. I don't know if the Mac Pro StepContextDict has been updated for better low power states as I haven't gone back and tested in Yosemite.

The version of pikes script used for this guide, created a SSDT that would override parts of the OEM (BIOS's built in) SSDT for cpu power management but the rest of the oem SSDT was needed in order for a complete ACPI table to be loaded at boot. Again, I don't know if newer versions of pikes script create a SSDT that can completely replace the entire oem SSDT as I've had no need to replace my current one. It should keep working forever unless Asus releases a BIOS update that radically changes the ACPI tables, which I highly doubt they will ever do for x79. It is possible that your board's ACPI tables load in a different manner than the RIVE and you get power management without the oem SSDT. Or pike updated his script. Don't really know.

By any chance would this guide work on ASRock motherboards? I have an ASRock X79 Extreme 6.

I managed to get C-states partially working on my build, can you think of any ways to get full C-state support?

This is what I have currently.

Looks good to me. You have c2, c3 & c6 residencies and "AICPUPMI: CPU P-States [ 12 22 (27) 32 39 44 ]" shows you reaching 12, 22, 27, 32, 39 & 44. If you want to go deeper than what I've outlined, contact PikerAlpha
