k3nny Posted October 3, 2013 Share Posted October 3, 2013 Hi, NullCPUPowerManagement.kext disables AppleIntelCPUPowerManagement.kext so you won't get that kernel panic. If you want to get rid of it, you need to patch AppleIntelCPUPowerManagement.kext.

k3nny Posted October 3, 2013 Share Posted October 3, 2013 Try to run it for a long time, you should get more states.

Vahids Posted October 4, 2013 Author Share Posted October 4, 2013 I think NullCPUPowerManager.kext is in cache ! cause when I use UseKernelCache=No in boot time osx won't boot. Right?!

k3nny Posted October 5, 2013 Share Posted October 5, 2013 I know that the number of performance states can also depend on the platform profile you use (MacBookPro9,2). You can try a different one and see if you get more states. Hopefully it helps.

Archer12 Posted November 25, 2013 Share Posted November 25, 2013 u may try my tricks.. actually to get speedstep working u need a patched AICPUPM, correct SMBIOS and correct SSDT. last week i only try to generate ssdt using sdtprgen, the problem is it can't detect low frequency mode in my processor. (same with you i think). so you will never get states lower than 12x. i have a solution, just create usb bootable with clover, and configure it to generate p-state and c-state, once you enter the desktop, check again with msrdumper it should be more states, and u get 8x states. u can dump it with maciasl.. good luck Link to comment https://www.insanelymac.com/forum/topic/292342-acer-aspire-e1-571g-core-i3-3120m-25gh-3mb-l3-cache-speedstep-issue/#findComment-1971419 Share on other sites More sharing options...
