Sapphire PULSE Radeon RX 5600 XT With Catalina : can not boot

[freed]

Hi all,

Cannot start on Catalina 10.15.4 when my Sapphire PULSE Radeon RX 5600 XT 6G is connected.
(new installation).
Here is my EFI and I have disabled Internal Graphics
the installation was done without the graphics card and catalina works. The problem is when I add the graphics card


GA-Z87X-UD5H
Sapphire PULSE Radeon RX 5600 XT 6G
CPU I7 4770k

Grand merci d'avance !!!

U should switch SMBIOS to 18.3, or 19.1 or iMacPro1.1
I'll recommend 19.1

EDIT Ok I tried with a Sapphire PULSE Radeon RX 5600 XT (Catalina 10.15.4) + agdpmod=pikera, it works perfectly. So you can use this graphic card for a future config.

I have the opportunity to upgrade from Nvidia GT740 to a AMD RX5600XT.

How should I do a fresh catalina installation? ATI injection?

Use the agdpmod=pikera boot arg and don’t inject ATI.

Agdomod=pikera gives micro lags

You can use the card without WEG, and the command.

Without WEG you need to disable the pikera boot arg.
Also, lilu.kext needs dependent Kexts so use Apple ALC.kext along with it.
