Suits builders using listed Ryzen 1st

This board works out of the box with the listed Ryzen 3, 5 and 7 processors such as the 1300, 1400, 1500, 1600, 1700, 2200, 2300, 2400, 2600 and 2700 models. Builders who need a 3rd or 5th Gen Ryzen CPU cannot use this board without a prior BIOS update performed using a compatible older processor.
