No, I didn't run Memtest. I fail to see how that could be a RAM issue, to be honest.Just to eliminate memory problems: did you tried a Memtest?

Nope, I didn't change anything in BIOS. And the issue happens with only one monitor connected as well.Just an idea... Any BIOS change parameters change? You say it happens in Windows and MacOS?
And if you remove one the monitors?
Although I have not seen any problem reports with the XFX RX 5700 XT (only with the MSI), the first thing to check is whether the Boot Arguments (in NVRAM section of OpenCore Configurator) contain agdpmod=pikera.
exactly!How do I add the agdpmod=pikera? Like after the alcid=1?
!!! DSM2 dropped the Alpine Ridge Thunderbolt Data Sheet at #1,319Thanks for this. Too often I see these magical firmware patches with no explanation of what changed or why. With proper documentation of each change like this, these patches can be built upon by others.
For my Mac Pro and other cases, my current plan is to work on a software only solution that doesn't require flashing. First step is trying to boot Ubuntu after enabling Alpine Ridge in EFI Shell.
Yes I was afraid that was going to happen because Apple has introduced new capabilities in APFS.
@byteminer — have you tried installing Big Sur public beta?
@CaseySJ Thansk for looking into it.If you post the IOReg file from your system and the Thunderbolt SSDT, I can get a better idea of what may be happening.
Please try the slightly modified SSDT attached. IOReg shows that the previous SSDT was not loaded because it's referring to a non-existent PXSX device. On PEG2 we have instead PEGP. The attached version makes this change.@CaseySJ Thansk for looking into it.
First here is my IOReg screenshot

Thank you very very much!
