kilian Posted June 2, 2014 Share Posted June 2, 2014 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 Extra.zip IOReg.zip Link to comment Share on other sites More sharing options...
aliab Posted June 2, 2014 Share Posted June 2, 2014 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? GAZ87XUD3H_CLOVER_UEFI.zip good luck 1 Link to comment Share on other sites More sharing options...
charliebounce Posted June 2, 2014 Share Posted June 2, 2014 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 Link to comment Share on other sites More sharing options...
kilian Posted June 4, 2014 Author Share Posted June 4, 2014 Thanks, changing to Clover is working perfectly. Federico Link to comment Share on other sites More sharing options...
