Technical Specifications
Technical Summary
The Gigabyte B550M DS3H AC motherboard, revision 1.1, is built around the AMD AM4 CPU platform with a Promontory PCH/southbridge. The board features four unbuffered DDR4 memory slots and utilizes an IR35201 plus IR3555 VR controller for VCORE/VCORE_SOC power delivery. Audio is handled by a Realtek ALC887 codec, while wired networking is provided by an RTL8111G LAN IC. System monitoring and LPC interface are managed by an ITE IT8688 Super I/O. Additional power regulation components include RT8120, NCT3103S, and RT8068A. The board includes an M2_WIFI slot for wireless connectivity and an RTS5441 card reader controller.
