Gigabyte B550M DS3H Rev 1.0 1.01 Schematic
Technical Specifications
Technical Summary
The Gigabyte B550M DS3H motherboard, revision 1.0, is built on the AMD AM4 platform with a Promontory PCH. The board utilizes an IT5702 EC/KBC and an IT8688E thermal sensor. Audio is handled by the ALC1220 HD audio codec, while networking is provided by the RTL8111G LAN IC and an M2_WIFI slot. The system supports four unbuffered DDR4 DIMM slots. Power management is managed by a combination of IR35201 and IR3555 VR controllers, along with RT8120D, NCT3103S, and RT8068A power ICs. The board includes an RTS5441 card reader and an IT5702 HDMI level shifter. The SPI BIOS flash is used for system firmware storage.
