in my experience the largest contributor to interference with BT is USB3. I have a NUC hackintosh that I use a BT dongle with, and I have had to use a USB extension cable to locate the BT dongle a couple of feet from the NUC. obviously with the Fenvi card providing BT this isn't an option, but if using a BT dongle it's worth a try.I have the same issue
Well, good luck...
It could come from your Broadcom module, antennas, storage drive, RAM, PSU, GPU; also from your PC case and even from your neighbor's micro-wave
I tried every combination possible (except GPU and PSU) and never found the issue
Next thing ill try is get out the motherboard from the case and try without the case

Does this mean you were able to run Big Sur on your Designare Z390 with AppleVTD present in IOReg, and WiFi/Ethernet failed to connect with 64GB RAM installed?
Thanks for the information. Two questions:I can confirm that Crucial Ballistix 2x16GB https://www.amazon.co.uk/dp/B083TRRT1L/?tag=tonymacx86-21 works with VT-d enabled and Ethernet & Fenvi WiFi are both fine.
no luck, i added the file to acpi and make sure it was checked in config
here is a photo of my bios setting for intel gpx
Attached is a modified SSDT. Simply disable the previous one and try the new one.Please post a screenshot of the ACPI section of config.plist (using OpenCore Configurator).
Yes. In Big Sur with Apple VTD present from i/o Reg Explorer, 4x16GB of RAM are present, but there is no ethernet nor wifi services, even if the network configurations are removed or reset: Network interfaces are not even manually configurable with VTD enabled. Still using the modified Z390 BIOS: Z390DESI_modMC_01052021_0906_Rev_0xEA.F9i 2 and unflashed Thunderbolt.Does this mean you were able to run Big Sur on your Designare Z390 with AppleVTD present in IOReg, and WiFi/Ethernet failed to connect with 64GB RAM installed?
