Hi,

 

I recently build up a new computer with the following components:

  • Mainboard: GA-Z87-D3HP
  • CPU: Intel Core i5 4570 (Haswell)
  • RAM: 2 x 4 GB Kingston
  • PSU: Corsair CW 600 Watts
  • HDD: WD Blue (500Gb) + SSD Samsung 840 Evo (128 GB) -> Fusion Drive
  • GPU: EVGA GeForce GTX 550 Ti

I got a full working version with Vanilla Install (which went very smooth), but no sign of P-states and AppleIntelCpuPowerManagement. I deleted NullCpuPowerManagement, using a Modified version of AppleCpuPowerManag. and tried to make an ssdt.aml with the script generator.

 

I've tried several things like: 

 

  • Using a iMac 15,1 Smbios (haswell product)
  • Using a ssdt.aml (with iMac model name)
  • Using patched AppleCpuPowerManagment 10.9
  • No NullCpuPowerManag. kext
  • No Generate P - C states strings on org.chameleon.Boot.plist
  • DropSSDT=Yes

 

  • Using a MacPro 5,1 Smbios
  • Using a ssdt.aml (with MacPro model name)
  • Using patched AppleCpuPowerManagment 10.9
  • No NullCpuPowerManag. kext
  • No Generate P - C states strings on org.chameleon.Boot.plist
  • DropSSDT=Yes

 

I got system working but no sign of P-States (just states 8,34,35,38)

I also tried to patch the kernel and no sign of AppleIntelCpuPowerManagment.

Should i use a DSDT? 

The string used for create the ssdt is "~/ssdtPRGen.sh -b Mac-F221BEC8 -c 2 -f 3200 -l 4 -m MacPro5,1 -p i5-4570 -turbo 3600 -t 84 -x 1"

 

Thanks in advance,

Federico

You have to use Clover,

 

get some tuto for installation

 

Just need to edit config.plist and put all kexts in S/L/E

"The important thing" to get correct Power Management is "DropTables key" in config.plist

have a look at these files updated for 10.9.3 and GA Z87X UD3H which is close to your motherboard and perhaps could help you?

good luck

Haswells are not designed to be using AppleIntelCPUPowerManagement. They use an XCPM instead aka Xnu Cpu Power Management. 

 

Follow this guide to Patch your Kernel (It works for 10.9.3 also) http://www.insanelymac.com/forum/topic/295587-power-management-for-sandyivy-bridgehaswell-cpus/

Make sure you are using the "-xcpm" argument.

 

More information here...http://pikeralpha.wordpress.com/2013/10/05/xnu-cpu-power-management/

 

All this is designed for a pure UEFI environment so I also suggest you use Clover or RevoBoot. Start with clover first, RevoBoot is a bit more complicated.

 

You may also want to disable certain certain UEFI BIOS features as described here... http://pikeralpha.wordpress.com/2014/05/26/major-breakthrough-for-power-management/comment-page-1/#comment-1522

 

Good Hack :)
