dmesg

Hi,

Since 5.2 kernel, my system (raven ridge 2400G,  Asrock X470 Gaming-ITX/ac,
latest bios, archlinux) crashes (black screen or green screen or flickereing
screen at start). I identified the issue with my RAM's speed, which is shared
between the GPU and CPU.
Everything above 2133Mhz crashes.
I dont have this issue with 5.1 kernel.
Dsmeg of the crash as attachment
