Easy UEFI BIOS update for instant compatibility with AMD Ryzen 3000XT processors
Updating an ASUS AM4 series motherboard for compatibility with the latest AMD Ryzen 3000XT processors takes just moments, via one of two simple methods.
With the ASUS-exclusive USB BIOS Flashback feature ― which is built in to selected ASUS motherboards ― users need only to download the latest UEFI BIOS to a USB flash drive and connect the motherboard’s power supply; then insert a FAT32-formatted USB drive and press the motherboard’s USB BIOS Flashback or Reset button. No AM4 processor or memory modules need to be in place, and the update will complete in a few moments.
Alternatively, users may update via the EZ Flash 3 utility that’s integrated with the ASUS UEFI BIOS. This tool allows the update to be applied via an inserted USB drive or downloaded directly from the internet.
