SavageAUS Posted January 21, 2019 Share Posted January 21, 2019 I think I have cpu pm working correctly on my haswell laptop but I don’t believe it goes below 1ghz. Can anyone let me know if this is normal for this cpu?

SavageAUS Posted January 21, 2019 Author Share Posted January 21, 2019 Check the LFM frequency indicated in the Intel datasheet for your Haswell CPU.I found this but not helpfulLow Frequency Mode. LFM is Pn in the P-state table. It can be read at MSR CEh [47:40].Sent from my iPhone using Tapatalk Link to comment https://www.insanelymac.com/forum/topic/337314-i7-4510u-cpu-pm/#findComment-2660402 Share on other sites More sharing options...
SavageAUS Posted January 21, 2019 Author Share Posted January 21, 2019 Thank you, so my cpu should be going down to 800mhz. I need to figure out what’s going on then.

SavageAUS Posted January 22, 2019 Author Share Posted January 22, 2019 I have tried using an ssdt from ssdtprgen, I have tried plugintype 1 and 0 but none of these let me cpu go down to 800, lowest I’ve seen is .98 on IPG.

SavageAUS Posted January 23, 2019 Author Share Posted January 23, 2019 (edited) I believe i managed to get cpu power management working correctly but is there a way to lower iGPU frequency? It is constantly running at 0.55 when at idle i think i read it should be .20? AppleIntelInfo.kext v2.9 Copyright © 2012-2017 Pike R. Alpha. All rights reserved.
