NezzariX Posted May 6, 2013 Share Posted May 6, 2013 I've tried a lot of things (both through the bios & patches), but I can't seem to get turbo boost working. I am stuck at 1.6Ghz idle and 3.3Ghz load. During my last attempt, I used the ssdtPRGen script to generate a new ssdt.aml without any changes. However, enabling DropSSDT causes my system to freeze while booting. Could someone please point me in the right direction? Booting with DropSSDT causes a NullCPUPowerManagement error P8Z68-V Pro Core i5 2500k Geforce 560 Ti Link to comment Share on other sites More sharing options...
k3nny Posted May 6, 2013 Share Posted May 6, 2013 Did you try running OS X without NullCPUPowerManagement.kext? Link to comment Share on other sites More sharing options...
NezzariX Posted May 6, 2013 Author Share Posted May 6, 2013 Did you try running OS X without NullCPUPowerManagement.kext? Won't that cause a kernel panic? Either way, I'll give that a shot right now. EDIT: Booting with DropSSDT and no NullCPUPowerManagement causes the system to hang with corecrypto.kext messages Booting without DropSSDT and no NullCPUPowerManagement causes the system stay at 1.6Ghz 100% of the time.

pfilipp Posted May 6, 2013 Share Posted May 6, 2013 I've got same problem on similar platform. Link to topic: CLICK - problem is still unresolved :< I have P8Z68-V/GEN3 with i7-2700K. I've got custom DSDT - fully patched - and SSDT generated by this SCRIPT. The weird thing is that if I just skip ssdt and let chameleon generate P&C states it reports about 13 states but anyway Mac uses only x16 and x35 no turbo or anything between. My smbios is iMac12.2 as it was released with i7-2600. Thanks for any kind of help Link to comment Share on other sites More sharing options...

When I extract mine, I get compilation errors even before I try to patch it. Link to comment Share on other sites More sharing options...
pfilipp Posted May 6, 2013 Share Posted May 6, 2013 First of all I forgot to say that I've got my bios patched with PMPatcher so that I won't need patched AICPUPM. About DSDT: When you extract your DSDT it's normal that you'll get some errors at the very beggining. I patched my dsdt using DSDT Editor and patch from THERE - you will need to register and than download patch for your mobo. There is one 'but'. If you are using 3k bios - the number that goes like 3XXX than you will need to choose 'P 8 generic patch' otherwise choose the patch with your exact mobo name in it. At first I had abou 12 errors, after applying patch I had only 2 left. I just googled them. To repair the remaining 2 of them I needed to change something like 2 or 3 lines in code - really simple as there are guides on the web. Good luck!

EDIT: I formatted my drive and started over using a premade Asus P8Z68-V Pro Bios 1101 DSDT. Everything works (turbo boost, sleep, etc). Link to comment Share on other sites More sharing options...
