ASUS ROG GA401II-HE004 RAM upgrade specifications

ASUS ROG Zephyrus G14 GA401II-HE004 RAM upgrade specifications include DDR4-SDRAM memory compatible with a single SO-DIMM slot. The laptop features on-board memory combined with one upgradeable SO-DIMM slot, supporting a maximum RAM capacity of 24 GB. Memory operates at 3200 MHz frequency. Upgrade specifications indicate the compatible memory type and maximum capacity for this specific laptop model.

Additional Notes

• The ASUS ROG GA401II-HE004 contains factory-soldered RAM that cannot be removed or replaced without specialized equipment and risks voiding the manufacturer warranty.
• The single SO-DIMM slot configuration limits future expansion to one additional memory module rather than allowing dual-channel upgrades through matched pairs.
• The 24 GB maximum capacity indicates 8 GB of soldered memory, restricting the SO-DIMM slot to a 16 GB module as the largest compatible option.
• Matching the 3200 MHz frequency specification prevents downclocking penalties that occur when mixing modules of different speeds within the same memory controller.
• DDR4 SO-DIMM modules require 1.2V operating voltage to maintain compatibility with the laptop's power delivery specifications, excluding DDR3L or DDR5 modules.
• The hybrid memory architecture using both soldered and socketed RAM typically operates in asymmetric dual-channel mode up to the capacity of the smaller module, with remaining capacity running in single-channel mode.
• Installing a 16 GB SO-DIMM alongside the soldered 8 GB creates a 16 GB dual-channel segment with the remaining 8 GB defaulting to single-channel operation, impacting memory-intensive workloads differently across the address space.
• CAS latency specifications must align with JEDEC standards for DDR4-3200, typically CL22 for consumer modules, to ensure stable operation without manual timing adjustments.
• The single-slot design eliminates the option to distribute thermal load across multiple modules, concentrating heat generation in one physical location within the chassis.
• Non-ECC unbuffered SO-DIMM modules represent the only compatible type, as ECC or registered memory requires different electrical signaling unsupported by consumer mobile platforms.
