Hey
This guide is good. But On my machine, CPU PM only works if I have 2 kexts :
* NullCPUPowerManagement.kext
* VoodooTSCSync.kext

If I'm using those kexts, it's not real PM?
If I remove NullCPUPowerManagement.kext, and follow this guide, PM is not working anymore.
NullCPUPowerManagement.kext is supposed to turn PM off but on my machine it turns it on, why ?

PM is so difficult to understand. So many kexts and methods and kernel patches. I would love a theoretical topics witch explain all that.

Thanks for any help!

Use the SSDT for your specific CPU, remove NullCPUPowerManagement.kext. VoodooTSCSync.kext is required for the CPUs having more cores.

Sorry about that, I should have included what you ask for. I was a bit exhausted after many tries and failures. I will make a full reply soon with more details. Thanks.

Hey, back with a proper PR:

Issue:
  • No PM after following both methods
  • CPU load seems to be full in Intel Power Gadget, but nothing heavy is running in activity monitor
  • CPU Freq is always high, CPU temp is high
  • 10.14.5
  • 5820k / X99-UD4
  • not sure how to provide a "Copy of IOReg", if needed please tell me
Other question:
The only way to achieve a PM is by using this kext: NullCPUPowerManagement.kext, with it my CPU is changing its Freq/Temp/Voltage on Intel Power Gadget, is it a good way to run my machine in term of performance and hardware durability?

THANKS a lot

The configuration is not upto the mark.
