Dontview Posted January 20, 2014 Share Posted January 20, 2014 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. 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? Thank you guys Link to comment Share on other sites More sharing options...
punchatron Posted January 21, 2014 Share Posted January 21, 2014 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. Link to comment Share on other sites More sharing options...
RehabMan Posted January 21, 2014 Share Posted January 21, 2014 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).

Joao Aurelio Posted January 21, 2014 Share Posted January 21, 2014 my 4670k has 8x 34x 35x 36x 37x 38x using smbios 14,2 and generate p-states <yes>, I will try another smbios and see what happens Link to comment Share on other sites More sharing options...
