Additional Notes
- The ASUS ROG GA402RJ-L4105W incorporates soldered memory on the motherboard, meaning only 1 of the 2 memory channels remains upgradeable through the SO-DIMM slot.
- Upgrading to the 24 GB maximum requires a 16 GB SO-DIMM module, as the on-board portion is fixed and non-removable.
- Single-channel operation will persist after any upgrade due to the asymmetrical memory configuration, resulting in reduced memory bandwidth compared to dual-channel architectures and potential performance degradation in memory-intensive workloads.
- DDR5-4800 SO-DIMM modules are widely available but represent a premium price segment; compatibility verification with ASUS documentation is necessary before purchase, as not all DDR5 SO-DIMMs operate reliably at this frequency specification on this platform.
- Installation of the SO-DIMM module requires access to the memory compartment and does not typically void the manufacturer warranty when performed according to ASUS specifications.
- Memory bandwidth asymmetry may create latency penalties in gaming and content creation tasks, partially offsetting the capacity gains from upgrading the removable slot.
