Gigabyte B550M AORUS PRO-P Rev 1.0 Schematic
Technical Specifications
Technical Summary
The Gigabyte B550M AORUS PRO-P motherboard, revision 1.0, is built on the AMD AM4 platform with a B550 chipset. It features a 10-phase VCORE and 3-phase VCORE_SOC power delivery controlled by an IR35201 PWM controller. The system memory architecture supports four DDR4 slots in unganganged 64-bit mode, with DDRVTT regulated by an NCT3103, VDDIO_MEM by an RT8120, and VPP_MEM by an RT8068A. The embedded controller is an IT5702FN MCU, identified by package code 10HP2-NW5702-A1R, and is programmable via SPI. Audio is handled by a Realtek ALC1200 codec, while networking includes an RTL8125 LAN IC and an RTL8118 for wireless clock generation. The board includes a GL850S USB 2.0 hub, an RTS5441 multiplexer, and supports dGPU to UMA conversion through component depopulation and BOM options. The SPI BIOS interface is present for firmware storage.
