Additional Notes
- The ASUS ROG GA402RJ-L4179W contains soldered on-board memory paired with a single user-accessible SO-DIMM slot, creating an asymmetrical configuration that limits total capacity to 24 GB despite DDR5 technology.
- DDR5-4800 MHz operation requires compatible SO-DIMM modules rated for this frequency; using slower DDR5 variants will downclock the entire memory subsystem to the module's rated speed, reducing overall bandwidth availability.
- Upgrading beyond the soldered allocation requires a SO-DIMM purchase, but the single slot design eliminates dual-channel configuration options and forces all upgrade capacity into a single module, creating potential latency penalties versus balanced dual-channel layouts.
- The 24 GB ceiling represents an odd-capacity constraint; standard DDR5 SO-DIMM modules ship in 8 GB, 16 GB, or 32 GB denominations, meaning a 16 GB upgrade module will be the only practical option to approach the 24 GB limit without exceeding it.
- SO-DIMM slots typically feature zero-insertion-force retention mechanisms; end-user installation poses minimal mechanical risk and falls within standard warranty coverage for most manufacturers when performed correctly.
- DDR5 SO-DIMM modules remain relatively scarce and command price premiums compared to DDR4 equivalents; supply constraints may restrict module availability or increase acquisition costs beyond traditional upgrade budgets.
