6.6.7 GPU Passthrough blank screen

Hey Guys, I've been trying and trying and trying....I can't seem to get secondary slot in my system to pass through to osx VM

 

I have had windows work with my primary slot a RX480 but then that stopped working. Right now I'm more focused on getting OSX vm to work correctly and then i'll work back to windows. Here are some specs:

 

**edit: also updated to latest bios this morning to see if that helped and no change

MSI b350m Gaming Plus

Ryzen 5 1600

16GB ddr4 2400

Radeon HD 6870 (to pass through to OSX)

 

Now i've got the rom file I applied ACS to get proper grouping of IOMMU I've read online and watched spaceinvaders tutorials and I'm kind of at a loss. Maybe I'm not searching the correctly terms online so I am sorry if this is a solved issue and I promise I have been trying my arse off to get this working. Its a fun process but I am at a complete stand still now.

 

Heres the VM log perhaps something I have simply misconfigured???

      Would this be domain id2? perhaps something I would need to also assign, passthrough to VM?
