ASUS ROG GA401IV-HE159T RAM upgrade specifications
ASUS ROG Zephyrus G14 GA401IV-HE159T supports DDR4-SDRAM memory upgrades through one SO-DIMM slot. Maximum compatible RAM capacity reaches 24 GB, combining on-board memory with the expandable SO-DIMM slot. Memory operates at 3200 MHz frequency. Upgrade specifications allow for single-slot memory expansion to achieve the maximum RAM configuration supported by the laptop model.

Additional Notes
- The presence of on-board memory means 8 GB of RAM is permanently soldered to the motherboard of the ASUS ROG GA401IV-HE159T, making it non-replaceable during hardware failures.
- Dual-channel memory performance is only achievable up to double the capacity of the soldered chip, causing any capacity beyond 16 GB to operate in a slower single-channel asynchronous mode.
- The single available expansion slot restricts memory upgrades to a maximum of 16 GB in that specific socket to reach the documented system ceiling.
- Total system bandwidth is contingent upon matching the latency timings of the fixed on-board module, as the BIOS will downclock the expansion stick to the lowest common denominator.
- Physical installation of a higher capacity module triggers a shift to Flex Mode memory architecture, which may impact frame rate stability in memory-intensive applications.
- Thermal constraints within the compact chassis necessitate the use of low-voltage modules to prevent heat soak near the soldered memory chips.
- Motherboard limitations prevent the use of high-speed XMP profiles, restricting the interface to standard JEDEC timings at 3200 MHz.
