Good morning all,
i tried to modify the DMAR ssdt, and now all the network interfaces and the antelope interface are working with four 16Go DIMMs in my z390 Designare. need to do further testing but everything seems to be ok for now. for those who want to give a try, here is the process:

Bios: Vt-d enable

Opencore:

1. copy this Attached SSDT-DMAR.aml in your ACPI folder
2. modify your config.plist

Boot Arguments -> Remove "dart = 0"
Kernel Section -> Uncheck "DisableIoMapper"
ACPI Section - Delete -> add this entry

ACPI Section - Add -> add this entry

Is this on Big Sur?

That totally sounds like a plan! Thanks — will try shortly.

I'm using it on Monterey and looks like it fixed the issues when AirDrop Continuity Handoff, Connection to AirPods Pro, RSSI stopped working after wake-from-sleep

If Apple gives us back Bluetooth API in next Monterey versions I can make more checks related to my issues and theses kexts

@CaseySJ
Could you give a try to the new SidecarFixup.kext to test new Monterey features? I can't do it by myself because my CPU is without GPU

Or maybe this is only for Real Macs ?

Please see Quick Reference spoiler at the top of Post 1. After doing Step 1 and Step 2, you can install Big Sur directly from Mojave (System Preferences --> Software Update). Always make a full bootable backup first!!

Holy $&#&$#!! You did it! It works on Big Sur!

Now we have AppleVTD enabled with more than 16GB memory and no WiFi/Ethernet issue!

Z390 Designare:

What was the thought process that led to this solution?
