I managed to install and power up a Sapphire Veg 56 in my Mac Prop 5.1.
Needed 2 x mini 6 pin PCIE to 8 pin PCIE cables. Tried 8 + 6 pin which didn’t work.
Running Mac OS X 12.01 Monterey using Martin Lo’s OpenCore 0.75 package,.
Now I have Thunderblot 3 SSDT enabled and if I plug a monitor directly into the Vega GPU, I can also get my Apple Thunderbolt Display working on the Titan Ridge card using an Apple TB2 -> TB3 adapter. Pass through cable from the Vega 56 to the Titan Ridge card.
If I reboot with just the ATD connected, the ATD works fine (warm reboot).
If I shut down and then start the machine up (cold boot) then the ADT does not show.
Any ideas?
