Problem with Sapphire Pulse Radeon RX 580

[Flaivo]

Hi,
recently i've rebuilt my Hackintosh with Opencore and Sonoma, after some trouble i've finally installed the OS, thw wifi is working and all seems fine.

For a clean setup i've used the internal graphic card on the motherboard (asus Z370 F, with i7 8700k, 32 Gb RAM), all ok with that card.

When I plug in the Sapphire Pulse Radeon RX580 (8gb) I can choose the boot from opencore but I got a black screen instead of the OS, sometimes it will restart and repeat the process. If I unplug the RX580 everything work properly again.

Anyone have experienced this kind of problem?

Make sure the monitor is connected to the GPU. Ensure it is installed in the X16 Slot. Try with HDMI/DP.
