ASUS ROG GA402NJ-L4061 RAM upgrade specifications

ASUS ROG Zephyrus G14 GA402NJ-L4061 laptop supports DDR5-SDRAM memory upgrade through a single SO-DIMM slot. The machine features 16 GB on-board memory with maximum upgradeable capacity of 24 GB. Compatible RAM operates at 4800 MHz frequency. Memory specifications enable users to expand the laptop's RAM capacity by installing additional DDR5-SDRAM modules in the available SO-DIMM slot, subject to the maximum RAM limit of 24 GB across all memory slots and on-board components combined.

Additional Notes

• The ASUS ROG GA402NJ-L4061 features a hybrid memory architecture with permanent onboard RAM soldered to the motherboard, limiting total system memory expansion to 24 GB regardless of the SO-DIMM module installed.
• The single SO-DIMM slot configuration forces an asymmetric dual-channel operation when populated, which may result in bandwidth throttling compared to symmetrical dual-channel configurations in memory-intensive workloads.
• DDR5-4800 represents the minimum JEDEC standard speed for DDR5 technology, indicating that higher-frequency modules will downclock to 4800 MHz when installed, eliminating any performance benefit from premium RAM kits.
• The onboard memory component is non-removable and non-replaceable, meaning any failure of the soldered RAM requires motherboard-level repair or replacement outside standard user serviceability.
• Calculating backwards from the 24 GB maximum capacity suggests 8 GB of soldered memory, allowing only a 16 GB SO-DIMM module as the largest compatible upgrade without exceeding the system limit.
• DDR5 SO-DIMM modules operate at 1.1V compared to DDR4's 1.2V, reducing thermal output but requiring strict compatibility verification since DDR4 modules are physically incompatible with DDR5 slots despite similar form factors.
• The mixed capacity configuration between onboard and SO-DIMM memory will trigger flex mode rather than true dual-channel mode, where only the matched portion operates in dual-channel while excess capacity runs in single-channel mode.
• Warranty preservation requires non-destructive installation procedures, as accessing the SO-DIMM slot through the bottom panel typically falls within user-serviceable maintenance under most manufacturer policies, unlike soldered component replacement.
• The 4800 MHz frequency specification indicates JEDEC standard timing rather than XMP/EXPO overclocking profiles, meaning performance tuning options through BIOS adjustments are likely restricted or unavailable on this platform.
