ASUS ROG GA401QE-K2118T RAM upgrade specifications

ASUS ROG Zephyrus G14 GA401QE-K2118T features DDR4-SDRAM memory configuration with one SO-DIMM upgrade slot. The laptop includes on-board memory paired with expandable SO-DIMM capacity. Compatible RAM modules operate at 3200 MHz frequency. Maximum supported memory capacity reaches 24 GB. Specifications enable users to upgrade storage by installing compatible DDR4-SDRAM modules in the available slot, subject to the stated maximum RAM limitation and frequency compatibility.

Additional Notes

• The presence of a single SO-DIMM slot combined with on-board memory indicates that only a portion of the total system capacity is replaceable, limiting future scalability compared to dual-slot configurations.
• The asymmetric memory configuration resulting from adding a 16 GB module to the existing 8 GB on-board chip will cause the system to operate in flex mode, where only the matched capacities run in dual-channel synchronization.
• Physical board constraints in the ASUS ROG GA401QE-K2118T necessitate the use of single-rank or dual-rank modules that strictly adhere to the 1.2V DDR4 standard to avoid thermal throttling or boot failure.
• Bandwidth is capped at the lowest common frequency if an aftermarket module with a speed higher than 3200 MHz is installed because the system lacks XMP profile support for overclocking.
• Replacing the single removable module does not void the standard hardware warranty provided the internal components remain undamaged during the mechanical installation process.
• Latency performance is dictated by the hardwired on-board memory timings, meaning high-performance modules with lower CAS latency will downclock to match the factory-soldered specifications.
