Additional Notes
- The ASUS ROG GA402XY-NC005W features a hybrid memory architecture combining soldered RAM with a single expansion slot, limiting total system memory to 32 GB regardless of the SO-DIMM module installed.
- The on-board memory component is permanently soldered to the motherboard and cannot be removed or replaced without advanced board-level repair equipment.
- DDR5-4800 represents the JEDEC baseline specification, meaning modules rated at higher frequencies will downclock to 4800 MHz when installed in this system.
- The single SO-DIMM slot creates an asymmetric dual-channel configuration where only the capacity matching the soldered module runs in dual-channel mode, while excess capacity operates in slower single-channel mode.
- SO-DIMM DDR5 modules require 262-pin connectors and operate at 1.1V, making DDR4 modules physically and electrically incompatible with this socket.
- The 32 GB ceiling suggests the soldered component is either 16 GB or 24 GB, as the system firmware enforces this maximum even if a higher capacity module is physically installed.
- Memory bandwidth peaks at 76.8 GB/s in dual-channel operation when both channels are actively utilized, though real-world sustained bandwidth typically reaches 60-65 GB/s due to protocol overhead.
- DDR5's on-die ECC feature operates independently of traditional server-grade ECC and cannot be disabled, providing background error correction without OS visibility or reporting.
- Upgrading through the SO-DIMM slot preserves manufacturer warranty as the base panel removal for access is considered user-serviceable maintenance under standard warranty terms.
- Mixing DDR5 modules from different manufacturers in the hybrid configuration is technically supported but may introduce stability issues due to differing PCB designs and power delivery characteristics.
