Impossible to say. Third generation Ryzen CPUs need a BIOS update in order to work on most B450 motherboards. If the motherboard has been sitting on a warehouse shelf for a while, it likely still needs this BIOS update. If it's recently from the manufacturer, it may already have the update installed. However, there is no way to determine that other than asking the store manager (if purchasing locally). If purchasing online, there is no way to tell.
