Short update: UEFIPatch can unlock MSR E2h and 1AAh on any of firmwares F5 to F8 for the C621-SU8 motherboard.
I have not succeeded to boot on firmwares F5 and F6. Firmwares F7 and F8 can boot with CPU wrapping (and SSDT-PLUG on the fake CPU objects). An SSDT-PMC as used by OpenCore on Z390 systems provides native NVRAM and allows to install Big Sur! Installers for Mojave and Catalina do not work, but it is possible to boot a system installed on another machine.

Hi.
Glad to know about this new patch. Any of you have an ideea if it could work on a dual CPU board? I have a Gigabyte C621-WD12.
Thank you

Sorry, just saw at the beginning of the post that it should work.
I’ll test it and share the results.
Thanks :)

Short update 2: With all OpenCore Booter quirks disabled except EnableWriteUnprotector, Mojave and Catalina install just fine. My C621-SU8 build finally ran smoothly as a Hackintosh, but a complete write-up has to wait because I currently need it 24/7 under Linux.

Looking forward to hear about your C621-WD12, and especially how it sleeps with two CPUs.
