ASUS ROG GA401QC-HZ003T RAM upgrade specifications

ASUS ROG Zephyrus G14 GA401QC-HZ003T features DDR4-SDRAM memory upgrade specifications with one SO-DIMM slot available for expansion. Maximum RAM capacity reaches 24 GB total, utilizing on-board memory combined with SO-DIMM slot configuration. Compatible memory operates at 3200 MHz frequency. Upgrade slots support DDR4 standard specifications, enabling users to expand system memory through the single accessible SO-DIMM socket for enhanced multitasking and performance capabilities on this gaming laptop model.

Additional Notes

• The ASUS ROG GA401QC-HZ003T features a dual-channel memory architecture with one channel permanently soldered to the motherboard, limiting repair or replacement options for that portion of the system memory.
• The 24 GB maximum capacity indicates 8 GB of non-removable soldered RAM paired with a single accessible slot that accepts up to 16 GB, creating an asymmetric memory configuration when fully populated.
• Asymmetric dual-channel configurations may result in reduced bandwidth for memory operations exceeding the capacity of the smaller channel, as only matching portions operate in true dual-channel mode.
• The single accessible SO-DIMM slot eliminates the possibility of installing two identical modules for traditional symmetric dual-channel operation.
• Mixing the soldered 8 GB component with a 16 GB SO-DIMM module still enables dual-channel functionality, though bandwidth utilization becomes uneven across the total memory pool.
• DDR4-3200 represents a JEDEC standard speed, ensuring broad compatibility with modules from multiple manufacturers without requiring manual BIOS configuration.
• The 3200 MHz frequency specification applies to both the soldered component and any installed SO-DIMM module, as mismatched speeds would force the system to operate at the lower frequency.
• Installing a module slower than 3200 MHz would downclock the entire memory subsystem, reducing theoretical bandwidth below the system's design specifications.
• Installing a module rated above 3200 MHz would not provide performance benefits, as the memory controller enforces the 3200 MHz ceiling regardless of module capabilities.
• The on-board memory component shares the same thermal environment as the motherboard, with heat dissipation dependent on chassis airflow rather than module-specific heat spreaders.
• Accessing the single SO-DIMM slot requires bottom panel removal, though the soldered memory remains permanently inaccessible without motherboard-level service.
• Total system bandwidth peaks at 51.2 GB/s when operating in dual-channel mode with matched or unmatched capacities, compared to 25.6 GB/s if only the soldered memory were present.
• Upgrading to the maximum 24 GB configuration provides headroom for memory-intensive applications while maintaining dual-channel operation across the first 16 GB of address space.
• The SO-DIMM form factor requires modules with 260-pin connectors and voltage specifications of 1.2V standard for DDR4, distinguishing them from desktop DIMM modules.
• Warranty considerations typically permit user-installed SO-DIMM upgrades without voiding coverage, though any damage caused during installation falls outside manufacturer responsibility.
