Gigabyte B550M AORUS ELITE Rev 1.0 1.01 Schematic
Technical Specifications
Technical Summary
The Gigabyte B550M AORUS ELITE motherboard, revision 1.0, is built on the AMD AM4 platform with a Promontory PCH. The board utilizes a Realtek ALC887 HD audio codec and an RTL8111G LAN controller. System management is handled by an ITE IT8688 Super I/O, while an IT5702 EC/KBC manages embedded controller functions and HDMI level shifting. Power delivery is controlled by an RAA229004 PWM controller supporting 5+3 phases for VCORE/VCORE_SOC, with DDR4 memory power managed by an RT8120 VDDIO_MEM regulator, an NCT3103S DDRVTT regulator, and an RT8068A DDRVPP regulator. The board supports four unbuffered DDR4 DIMM slots and includes an M.2 WiFi slot for wireless connectivity.
