X79 Ivy Bridge dual CPU setup - can't get CPU PM to work (kinda solved)

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

So my struggle is in the title - can't get XCPM to work on X9DRi-LN4F Mobo with dual Xeon E5-2690v2 CPUs running Cataling 10.15.14 on OpenCore

Setup details along with most important system outputs can be found here - https://github.com/AMar4enko/hackintosh-journey/tree/master/X9DRi-E5-2690v2x2

Any suggestions are welcome, can switch from OC back to Clover if needed.

UPD. Okay, it's kinda solved now - looked through boot log carefully and noticed there was an error loading CpuPm ACPI table, generated by ssdtPRGen script, complaining on logical CPU 21 (20 cores with HT enabled results in 40 logical CPUs). Disabled HT in BIOS then regenerated SSDT and plugin-type=1 was successfully set for CPU0 thus working PM.
I'm still wondering why it's not XCPM - applied 10.15.4 xcpm_bootstrap patch for Ivy Bridge-E from https://github.com/CloverHackyColor/CloverBootloader/commit/dca2aafe40eb7396fae4463ac4044db734ffe25b and can see it applied correctly from OC boot log, but machdep.xcpm.mode=0.

I'd love to hear if someone has anything to add

Extract tables with F4 key in Clover boot screen, boot into system and run this app
