Hello everyone,

have a question about Haswell CPU Power Management.
I’ve used ssdtPRGen.sh in order to get different P-States generated.
So far, mavericks shows me following message while booting up:
 

AICPUPMI: CPU P-States [ (8) 10 11 12 13 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 ]

However, in practice it seems, that my CPU jumps from 800 mhz straight up to maximum mhz.  :thumbsdown_anim: 
Is there anything i can do, to get all the other P-States running? Why is it showing me all this P-States, while in practice it just use 2? :help: 

Thank you guys

I'm having the same issue. HWmonitor shows clock going from x8 to x34 without using anything in between. Using a Gigabyte GA-Z87X-UD4H.

It is hard to tell what is really going on with HwMonitor. HwMonitor is not appropriate for pstate monitoring. Better to use something like MSRDumper.kext, AppleIntelCPUPowerManagementInfo.kext, or DPCIManager to track pstates. But it is normal to jump from idle to nominal with certain smbios (such as iMac).
