@izo1 I'm running BS release w/o particular problems, only the DP audio of my R7 doesn't work. As I have the same system as yours, can you share your EFI? Do you remember? I made my 1st Catalina OC installation with your EFI last august ... :)

Here you go, but keep in mind I still have some refining to do, but it should get you started. The RAM portion in PlatformInfo>Memory needs to be modified for your system too if you don't have 128GB of RAM. You can delete it, but you will get a RAM notification error.

It's currently on OC 0.6.3, once 0.6.4 is out next week (Monday) I will re-upload.

Update of Big Sur has worked everytime, but now i'm stuck in an update loop. I am on 11.0.1, and downloaded the 11.1 beta 2:

But when updating, i get to choose in OC menu, between Macintosh HD and BIG SUR. i pick big sur and it says 10 minutes remaining, then MacOS boots up and i get to enable or disable siri. (setting up new mac), and then it's back on 11.0.1 again..

I also had to resign into iCloud and had to force shutdown in the middle since it froze but mine updated to beta 2.

Can anyone confirm if ASUS Prime X299-A has a working NVRAM? I am considering to swap my MSI Raider X299 board - which has broken NVRAM.

I got that board and I'm on Big Sur, updated flawlessly and I gotta say my system has never been more stable with 11.0.1 Definitely Apple did a good job this here (and Acidanthera too ahahah). I can't list even a single thing that doesn't work ok, a part from my VA displays... terrible color shifting! Anyone can suggest good IPS panels?

Yes It will work with OC 0.6.4, I use it and the update to 11.1 beta 2 went smoothly.

Are you running your Extreme Encore on Big Sur?

Does your PCI tab look like this?
