Quick Guide to Generate a SSDT for CPU Power Management

[pH24]

Certain plists in X86PlatformPlugin are HWP enabled.

Note: Just because HWP is a hardware controlled CPU PM mechanism, does not mean it cannot be tweaked/adjusted by software.

Yeah, the latest Mac mini smbios I am using have hwp enabled. My question is that do EIST and hwp get along? Which takes the charge or has the say of which frequency cpu needs to stay in?

HWP (aka SpeedShift) is essentially hardware controlled SpeedStep.

If you're interested in how software can control HWP, you should read the documentation (programmers guide) provided by Intel.

Got it. Btw, the fakesmc companion kext for reporting cpu voltage is not working properly for me(your fork). It shows 0.6v most of the time. Are there any methods tweaking it or reporting bug etc? My board is Asus prime A z370.

If you're referring to FakeSMC_LPCSensors.kext, you'll need to look into creating a profile for it or fixing the code.
I don't have your hardware, nor do I actually use any of the sensor kexts.

 

[StepBystep]

When i load kext from desktop my mac is restart. What wrong?

Are there any tutorials for creating the profile? Btw, I turned off speed step and C states in UEFI. OSX still manages to cool my CPU frequency down. Is that fine?

No. You must refer to existing examples in the plist and read the source code for further details.

Some BIOS settings are probably ignored when running macOS.

 

[sunnyj]

Do the clover settings look okay for SSDT for USB and Power?

I left the Hackintosh encoding videos all night and the CPU frequency is dropping down to 1.9GHz after encoding

I also tried overclocking by changing the multiplier to 46 and changing the voltage to 1.275. On restart the computer would freeze at 0% of the apple progress bar and then throw a kernel panic (screenshot below)

XMP is enabled in bios to give me 2666MHz ram.
