<< Solved >> Asrock Challenger D 4GB RX 5500 XT won't work with the Pikera flag?

[RMJ114]

After setting up my iGPU and installing Catalina to my GigaByte Z390 UD and UHD 630 iGPU, I install my Asrock RX 5500 XT Challenger D 4GB graphics card and added the launch flag "agdpmod=pikera"

Is there another flag? or does it only wprk for the 5700 XT cards?

OK, I continued and searched for 5500 XT some more and found the opencore list of AMD supported GPUs and it saud DP may have issues on some models, so I plugged in my HDMI, and VIOLA! My GPU is displaying again. About This mac reports Radeon RX 5500 XT 4GB. and it shows up in system report. Not sure how tofind HW acceleration or not?
I guess I'll just have to install a game or two and test.

Did you leave

agdpmod=pikera

option?

Does your card work via DP ?

I just bought MSI Radeon 5500 XT and am trying to make it work but stuck on black screen.
