Additional Notes
- The ASUS ROG GA402XY-NC020W contains a single SO-DIMM slot paired with soldered on-board memory, restricting total capacity expansion to 32 GB regardless of DIMM density improvements in future DDR5 generations.
- SO-DIMM DDR5 modules rated for 4800 MHz may operate at lower effective frequencies if the replacement module carries a lower JEDEC or XMP profile, creating potential performance asymmetry between on-board and user-installed memory.
- Single-slot architecture prevents dual-channel memory configuration; performance remains constrained to single-channel bandwidth relative to dual-DIMM systems operating at identical clock speeds.
- Warranty coverage for memory upgrades typically requires purchasing OEM-approved SO-DIMM modules; aftermarket DDR5 SO-DIMM components may void thermal or component-level guarantees despite technical compatibility.
- Physical access to the SO-DIMM slot may require chassis disassembly beyond simple battery or M.2 storage compartments, imposing service complexity that affects installation feasibility without specialist tools.
- Maximum addressable memory of 32 GB represents a hard ceiling; workloads requiring 48 GB or higher capacity cannot be accommodated through internal upgrades on this platform.
- DDR5-4800 specification indicates support for JEDEC standard frequencies; DDR5-5600 or DDR5-6000 modules may fail to initialize or revert to lower frequencies without BIOS updates that may not be available for this specific SKU.
