MP 7,1 Mac Pro 7.1 and Amd radeon rx 6900xt

[thenightflyer]

Hello to the community! I own a Macpro 7.1 with his Radeon pro 580X in MPX module. I would try to "upgrade" my video card buying an AMD Radeon RX 6900xt (the reference version of AMD no other custom brand like XFX etc,)
Users who did this upgrad can confirm that there are no problems with macpro 7.1? In particular we know that rx6900 uses pci-e 4.0 and mac pro logic board is pci-e 3.0 so are there problems?

Many threads dealing with these cards in the 7,1. It works fine.

I use a simple 32" monitor HDR not the XDR display so i can connect it directly to my monitor input

I have a Gigabyte RX6800XT. My monitor is the Apple LG UltraFine with only TB inputs. I'm using this cable with the Gigabyte card:

Monoprice Bidirectional USB Type-C to DisplayPort Cable - 4K@60Hz, Black, 6ft - Monoprice.com

No longer will you be limited by the direction of your cable! This Bidirectional USB-C? to DisplayPort? Cable allows you to connect your legacy DisplayPort devices to your newest USB-C enabled display

My MPX 580 is still in the Mac in slot three.

Sorry for the delay - could you get four 6900XT in there (forget the power delivery that can get sorted)?

I have succeeded in using the 6900xt in getting 8k working.

Nope, I think you can get 3 of them in slots 1, 3, 5. I have a Sonnet 4x M2 SSD in slot 5.

Nobody knows exactly how many GPUs MacOS will currently enumerate?
