[Solved]AMD Radeon RX 850 Black Edition

Dear friends of the forum
I currently have a hackintosh with Catalina 10.15.3
I wanted to insert an AMD Radeon RX 850 Black Edition video card from the XFX
Unfortunately, after several attempts to add Kext and some changes to Clover, the card disconnects the signal from the monitor
after the apple logo, and it doesn't go further.
I was reading on the web that the Radeon 580 would have been fully compatible.'m not working in my case,
Could you help me to solve the problem?
Or is the card actually not compatible with any mcOS?

Thank you

This is the compatibility list
https://khronokernel-3.gitbook.io/catalina-gpu-buyers-guide/modern-gpus/amd-gpu

so being a Black Edition, even if RX 580 is not compatible then?

Thanks for the info chris1111
