Does anyone have experience using the Radeon Pro V620 in a 7,1? It seems like a solid option at current prices for a dedicated compute card but I don’t know how it would play with the system fans only and whether Metal would actually prefer it as a compute device given how opaque that selection can be. Any feedback is very welcome.
Got a tip for us?

I don't know if the V620 has been confirmed to work. I suggest to ask a seller if you could try one (if they allow return if it doesn't work).
I purchased a PowerColor Red Dragon Vega 56, put it to my cMP 2009 5.1 (upgraded from 4.1) with firmware 144.0.0.0.0 and Mojave. After Power On, the graphic card’s fan spins, the startup chime sounds, but it doesn’t output any video signal to monitor afterwards. I have done the VRAM reset, connected monitor to all output ports with various cable e.g. HDMI to DVI, Display Port to DVI. Does anybody meet the similar issue ?
Attachment is GPU-Z info of it from the seller.
It works fine on my PC linux, so I guess it is not physically broken.
It comes with the same VBIOS as J8320JAD.ROM(primary), J8320JAB.ROM (secondary). I tried to flash some other VBIOS to secondary, all of them can work on PC Linux, but cannot make it work on cMP.
I implement PSU Pixlas mod to replace power from motherboard, it doesn’t help either.
I also tried to install OpenCore + Monterey, it doesn’t change any situation.
I am running out of ideas about it. Any hint will be appreciated.
Thank you in advance.
