Additional Notes
- The presence of on-board memory means a portion of the system RAM is non-removable and soldered directly to the motherboard.
- Upgrading the ASUS ROG GA402RJ-L4044W requires matching the 4800 MHz frequency of the soldered module to prevent the system from downclocking to a lower common speed.
- Dual-channel memory performance is only active for the capacity where the SO-DIMM and soldered RAM match in size, while any excess capacity operates in single-channel mode.
- The single available SO-DIMM slot acts as the exclusive hardware interface for physical memory expansion.
- Latency timings are dictated by the slower of the two memory banks, necessitating compatible CAS latency ratings to ensure system stability.
- The 24 GB maximum limit indicates that the firmware or hardware architecture restricts the density of the module compatible with the single expansion slot.
- Asynchronous memory configurations resulting from uneven module sizes can lead to bandwidth bottlenecks in memory-intensive applications or integrated graphics tasks.
