I also have problems with the B550-F running RAM with more of 3200MHz. I tested two kits of which one was listed as compatible on ASUS now deleted QVL Ryzen 5000 List: https://abload.de/img/qvl6gk1p.png
I hope ASUS is aware of this problem as i cant find any official statement. I am running 3200MHz CL18 right now which is really bad and not what i paid for. I want to know if we can expect a solution for this or if i should refund my board. This is really annoying... I already contacted ASUS Support, but no answer for now.
Has anyone a soultion? I already tried raising DRAM and SOC voltages but literally anything over 3200 is instanstly dead. I heard of old BIOS revisions which work(ed). DOes anyone have one of those to share. Even though i wouldnt like the older AGESA i would definetly try it.
