Hi guys! I just built a new PC to start with my first ryzentosh, but I am having some issues. I am a beginner and at the moment I just managed to make work a highly compatible configuration like the HP 8300 both with Clover and Opencore. My new configuration has the following components:

Mainboard Gigabyte B550M DS3H
CPU Ryzen 3 3100
GPU RX460
RAM G.Skill 2x8Gb 3200

I set up Opencore by following the guide by Cortania. The installer loads but it shows weird artifacts, like in the picture I posted. Any idea what the problem might be?
In the link, you can also find my EFI folder and my config.plist file.

Update to the latest BIOS revision. It seems to be related to AGESA.
Thanks man! It worked. :)

Now everything seems to be working. The only issue is an error that I get every time I run macOS . It's about mismatched RAM modules and maximum supported memory (see picture below). Should I change the ram modules' position on the motherboard?
Currently, I am using the slots suggested on the mainboard's manual for the first two modules.
