Gigabyte B550M GAMING Schematic
Technical Specifications
Technical Summary
The Gigabyte B550M GAMING motherboard, revision 1.0, is built around the AMD AM4 CPU platform paired with the Promontory PCH. The board features four unbuffered DDR4 memory slots and utilizes an IR35201 plus IR3555 power stage for VCORE and VCORE_SOC regulation. Audio is handled by the ALC1220 HD audio codec, while networking is provided by the Realtek RTL8111EP LAN IC. The embedded controller is an IT8688E LPC SIO. The board includes a RTS5441 card reader controller and a TUSB321_A31 USB hub IC. Power management components include the RT8120D for VDDIO_MEM and the NCT3103S for DDRVTT.
