These Patches worked flawlessly with my build. Thank you. I ran some bench marks afterwards and the patches improved the performance of the Z620 hackintosh build. Fantastic work!

Yes, it works like a charm.

Thanks for your help.
The link on x86PlatformPlugin.kext.for catalina is 404. Do you happen to have it around? (I'm testing this on big sur but I'm gessing it would work anyway).

The link has been fixed. That shouldn't work due to the change in kext. However, feel free to try and report.

Sadly it did not work.

Attach your CPU PM SSDT.

Here we go.
(its name SSDT.aml in the ACPI folder)

Your SSDT doesn't have XCPM.

Thanks a bunch mate! I have x86plugin finally loaded!

I was able to make de ssdt with version 16.7, otherwise, version 21.5 would get mad. Thing is that 16.7 does not have the cpus argument and I cannot address that I have 2 cpus as 21.5 does.

21.5:
Warning: No ACPI Processor declarations found in DSDT!
Using assumed Scope (\_SB) {}

Number of Scopes: 1

Error: Processor name(s) not found ...
Aborting ...


This is the 21.5 log with:
~/ssdtPRGen.sh -p 'E5-2670' -x 1 -target 0 -c 3 -cpus 2 -l 32 -mode custom -d 3

Untitled - Pastebin

Thanks again!

That''s a very common issue.
To fix it, follow the steps below.

Extract the ACPI set from your system.
Copy the SSDT1-cpu-def file and the apic.aml file to Desktop.
Rename the ssdt to dsdt.aml
