I've got PM working 
The problem lies in AppleIntelCPUPowerManagement patch. I take it from a guy here. The two issues left are: random restart and audio

What happens when you use SSDT-PLUG, SSDT-PMC, SSDT-PM and SSDT-X79
CPU Power management just doesn't work. Frequency of all cores is stable at 2.6Ghz and Usage is always 100% no matter I let the PC idle or run geekbench test. All solutions I've tried so far giving the same result.
I expect it's idle at 1.2Ghz with almost 0% usage and reach 3.3 Ghz all core while testing with geekbench
-
Now just use SSDT-PLUG and SSDT-X79 nothing else and check
You mean SSDT-PLUG, SSDT-PM and SSDT-X79? It's still no use for me.
Also while creating SSDT-PM you need to have two options enabled in the ACPI>Delete section
1. First enable those two options in the ACPI>Delete section and reboot
2. Now create SSDT-PM
3. Disable those two options and then reboot
Yes, I followed that
-
Still not working. Is it because of the SSDT-PM.aml file?
I actually got this error when generating it. I chose y to ignore it. Is that ok?
-
Is the Mac booting without the SSDT-X79?
Yes. Here is my EFI with config.plist and SSDT files
-
Now add SSDT-UNC, SSDT-EC-DESKTOP and disable SSDT-X79 and check if it's working
It's still not working
-
I've added those SSDT files you mentioned but PM is still not working. I generated my SSDT-PM using ssdtprgen. Could you check if there is any issue with it?

I've got Monterey installed now but there are several issues:
1. PC restarts during boot process before reaching Apple logo screen at very high rate. Let's say I can boot into Monterey only once in 3-4 tries.
2. CPU power management is not working
3. Audio is not working -
What happens when you try the EFI from the author of this thread?
Using taube111111's EFI with dual CPU makes my screen gets stuck at the same point mentioned above. Single CPU setup with his EFI makes my PC restart during boot process so I haven't tried to modify it further.
-
After installing we will try to enable dual CPU. But with the latest EFI you should be able to boot in with Dual CPU. No worries we will see. After installing we will try the Patched DSDT
Actually, I have been using your latest EFI with USBMap.kext is the only modification to get USB keyboard and mouse work (along with turning off XHCI hand-off and EHCI hand-off). I mentioned above that I cannot boot with dual CPU. The screen gets stuck at
[EB|#LOG:EXITBS:START]With single CPU, I can pass this point.
-
robcodemax you are just genius!!
Turning off XHCI handoff and EHCI handoff solved my problem
I cannot boot with dual cpu though. So i will install with 1 cpu then
-
I tried your EFI. Without USBToolBox I can boot into the recovery image but usb keyboard and mouse won't work. Using UsbToolbox makes my PC restart during boot process. It seems that the same will thing happen if I use other USB-related kexts such as USBInjectAll. Please note that I have xhciportlimit disabled in config.plist as it won't work on mac 11.3 or later.

I can't boot into mac recovery with dual socket. I will try to install with only one cpu then
-
It's SCK1. The DSDT I sent you in the beginning was the one for dual socket.
-
no you're not wrong. I used dual cpu setup actually. But I failed to boot into mac installer so i unplugged power cable of the second socket to try.
I cant boot into recovery image now. Very likely due to the usbtoolbox. I will try with your kexts. But even I can boot now, installing from recovery will take alot of time as my internet now is tereibly slow to download mac
-
It's socket 0 actually. Btw, I've used USBToolBox before. I thought we have to remove UTBDefault.kext once we get our own UTBMap.kext.
-
Hurray!!! Disabling DSDT and keeping the 3 SSDTs worked. I can boot into the recovery image now
But I cannot control my USB mouse and keyboard. Let me try to use the usb mapping.
-
This error is fine as long as the installation is going forward. Is the installation going forward?
If you are stuck then don't use PLUG, PMC AND UNC
Hm it seems to get stuck there. I think I had waited for more than 5 minutes. I can give another try. I will try to disable those SSDT too.

PLUG, PMC, UNC and DSDT is enough. Rest everything is already added in DSDT.
If you are unable to see your EFI then
config.plist -> Misc -> Boot -> HideAuxiliraly Disable itAlso insert the pendrive in USB 2.0
You are not able to even boot or you are stuck in boot screen or what is the error message ?
HideAuxiliraly really did the trick. I use my PLUG, PMC, UNC and the fully patched DSDT as you suggested but now I face with another error below.

Did you try to use my EFI Folder?
Please use my EFI Folder just remove the UT Map.kext and use your UTBkext.map. You can create this in windows using USBToolbox
Also use your SSDT-PMC and SSDT-PLUG created using SSDTTime
Please use my EFI Folder and only change the following. Rest keep it as is
In ACPI
SSDT-PMC (Create using Windows ssdttime)
SSDT-PLUG (Create using Windows ssdttime)
DSDTFULLPATCHED
and remove my SSDT-PM-ROBERT-2021 (No need of this while installing) You can create your SSDT-PM later using ssdtprgen method
I have tried to use your EFI with DSDTFULLPATCHED you gave along with SSDT-PMC and SSDT-PLUG generated by SSDTTime. But there is no option to boot into installer. I put the recovery image in com.apple.recovery.boot folder as mentioned here and it does show an option to boot into that with my EFI.
Though there are many SSDT files in your ACPI folder, there only 3 of them are used in your config.plist: SSDT-UNC, SSDT-EC-DESKTOP, SSDT-EC-USBX. So I have to modify the your config.plist to add 2 entries for SSDT-PMC and SSD-PLUG.
The question is: Do I need to keep your 3 files above in the modified config.plist?
