Technical Specifications
Technical Summary
This ASUSTeK CFL-H platform motherboard, board number G703GINB1 RD2 EE1001 revision R1.0 dated April 28, 2020, features a dual-platform architecture combining an AMD Renoir FP6 CPU (45W TDP) with an NVIDIA N18E-G0 GeForce GTX 1660 Ti discrete GPU. The system memory configuration includes on-board DDR4 3200 MHz modules plus one DDR4 SO-DIMM slot per channel. The embedded controller is an ITE IT8225, with a separate ITE IT8299E handling keyboard backlight control. Audio is managed by a Realtek ALC3288 codec paired with a TAS5825MRHBR smart amplifier. Networking is provided by a Realtek RTL8111H-CG LAN controller and an M.2 2230 WLAN/BT module. The charging subsystem uses an ISL9238BHRTZ-T slave charger with a TPS65993AC PD controller. The HDMI output is supported by a PI3DPX1203BZHEX retimer and level shifter. The SPI ROM for BIOS is located on page 30 of the schematic.
