Stuck on OpenCore boot [Alienware Area 51 R2]

[Sylvain60]

Hi everyone,

I am trying to get my Alienware Area 51 R2 working again with mac os.

Config:
- Alienware Area 51 R2
- X99 chipset
- Intel Xeon E5 2683 v4 16c 32v previously Intel i7 5930k
- MSR E2 disabled
- 32 GB RAM DDR4 non-ECC 2400Mhz
- AMD Radeon VII GPU

Context:
Before upgrading my CPU, I was able to boot onto Windows and Mac Os Monterey without any problems.
But since I have changed the CPU, Windows working without any problem but it's impossible for me to boot onto Mac OS again.

I tried a lot of differents configurations, getting back to clover, building a new opencore efi from scratch, modifying bios settings ...
Nothing change.

I hope i've missed something obvious that you can point to.
Attached, you can find the OC debug txt, the xeon config.plist and the old i7 config plist.

Thanks in advance

Sylvain
