Additional Notes
- The ASUS ROG GA402RK-L8152W uses a hybrid memory configuration with soldered on-board DDR5 and a single expandable SO-DIMM slot, meaning only partial capacity upgrades are possible without desoldering.
- DDR5-4800 modules operate at JEDEC standard speeds; replacement modules must match this frequency to avoid automatic downclocking of the entire memory subsystem to the slowest module's rated speed.
- The single SO-DIMM slot creates an asymmetrical dual-channel configuration if populated, potentially reducing memory bandwidth efficiency compared to matched paired modules on systems with 2 slots.
- SO-DIMM physical dimensions (67.6 x 30 mm) are smaller than full-size DIMM modules; compatibility verification against the exact socket revision is mandatory before purchase, as DDR5 SO-DIMM pin assignments vary by generation.
- 32 GB total capacity ceiling (likely 16 GB on-board + 16 GB SO-DIMM maximum) constrains workloads requiring 48 GB or higher memory configurations.
- DDR5 memory operates at 1.1V nominal voltage; third-party modules with non-standard voltage specifications may trigger BIOS warnings or automatic downclocking as a protective mechanism.
- Upgrading the SO-DIMM slot does not void most manufacturer warranties when using OEM-approved modules, but non-approved modules may forfeit memory-related support coverage.
- The latency penalty between on-board soldered RAM and SO-DIMM expansion can introduce 1-3 nanosecond asymmetry in access times under sustained load, affecting latency-sensitive applications.
