Same issue here, when I install 18.7.1 the screen flickers to black every few seconds. As soon as I install 18.5.1 the screen flicker stops.
Motherboard: Asrock Fatal1ty AB350 Gaming-ITX/ac
BIOS version 4.50 (not latest, just upgraded to latest and will test 18.7.1 again)
CPU: Ryzen 5 2400G (everything to default)
Memory: Corsair Vengeance LPX CMK8GX4M2B3200C16 (set to 3200MHz)
Settings Ryzen Master: default
Monitor: Older Harman Kardon receiver connected to monitor, no HDCP support
use to latest bios

to low voltage for your ram
try atleast 1.35V to be rock stable // 1.4V is also ok
what is your VDDRC SoC Voltage? i prefer 0.7V
also 1.1V VSoC is needed
increases ram voltage to 1.35v, MEM VTT to 0.675, Vddcr soc is set to 1.1v currently. Ryzen Master doesn't show anything else.
the BIOS won't let me change any voltage of speed for cpu/GPU/ram.
the system does seem a lot more stable now. Never thought of increasing the voltage beyond default since it wasn't a computer designed for gaming
Thanks a lot
I'll try again the driver upgrade tonight.
glad i could help
those kind of instability usually comes from "fresh" products - and MoBos with half-finished Bios (like my GA-AX370-Gaming 3 or Gaming 5 have arful bios - but the biosmod from ket for my Gaming 5 is brilliant)
some bios can be unlocked by a hotkey or key-combo
others have those spoken about mod-bios
