Yes @djlild7hina provide useful recommendations ( thanks :clap:) so we may continue on the X299 OC thread. ;)

Here are your system SSDTs and for the OC SSDTs on the OC thread
NB : the SSDTs are from Kgp repo but adapted for some to your system

So I have to inject all of them in ACPI folder/config.plist of Opencore? I suppose I have to leave EC-USBX + PLUG + RTC0 + SBUS as they previously are in my EFI?

Thanks for your work, really appreciated. Hope someone else with Prime x299-a will enjoy this.

Yes put this on ACPI and you must edit your OC config.plist ( with Xcode or TextMate) but you will also add the SSDTs linked by @djlild7hina
SSDT-EC-USBX-X299
SSDT-PLUG-X299
SSDT-SBUS-MCHC ( required for OC)
SSDT-DTGP
(With the Titan Ridge I also add SSDT-XOSI)

And after we will meet us on the X299 OC thread ;) TYA (Exciting the X299 system)

Note that you don't need SSDT-DTGP if you have SSDT-SBUS-MCHC. the DTGP method is already included :) So make sure SSDT-SBUS-MCHC is first in your config.plist, since other SSDTs may reference that method. Also this thread is kinda like a second OC thread since mostly everyone moved to OC. :lol:

Yes, it was quite long and sometimes difficult to adopt OC for me ( It felt like I was still at my own job :D ) but necessary for the future...

Ok, it boots and it seems snappier! Attached new IOReg and screen of PCI Devices.

I tried multiple reboots, goes every time but I noticed that the 1st time the audio "pop" feedback when you raise/low volume from keyboard was super fast (popped at every key press even if I fast repeat presses) but from 2nd time on it pops only at the last bar, exactly how it did with the old EFI. Maybe an NVRAM reset is needed? Waiting for your general feedback.

EDIT: after a sleep/wake cycle the "pop" is super responsive (also, just like the old EFI)
