How to use

Install the AM4 CPU, apply compatible DDR4 memory modules into the four DIMM slots, and connect power using the solid-pin 8‑pin ATX 12V connector and main ATX power. Mount M.2 SSDs into the M.2 sockets or connect SATA drives to SATA III ports. Connect front-panel USB Type-C devices to the onboard header and attach display to HDMI or DVI-D outputs as needed. Use the UEFI AMI BIOS for initial configuration, enable XMP/DOCP profiles or adjust fan curves and RGB settings via the included software utilities (EasyTune™, RGB Fusion 2.0, Smart Fan 5). To update BIOS without CPU, memory or GPU installed, save the renamed BIOS file (gigabyte.bin) to a USB drive and use the Q-Flash Plus button.

Recommendations

For optimal performance pair this B550 motherboard with a 3rd Gen or newer AMD Ryzen CPU, high-quality DDR4 memory kits (matching dual-channel configuration), and NVMe SSDs for the fastest storage. Ensure your case supports ATX form factor and provides adequate airflow; configure Smart Fan 5 profiles to maintain safe temperatures. Use the latest BIOS from the manufacturer before heavy workloads or new CPU installs.
