Question about ASUS ROG STRIX B550-F GAMING

Correct. A bios update must be carried out. But everything is not so bad. To be more precise, it is quite easy. You should only load the bios onto an empty usb stick in advance and then flash it from there. I have the same board with a Ryzen 7 5800x.

Momental still 1801 beta, but works fine.
