Additional Notes
- The ASUS ROG GA402RJ-L4028W contains a single memory slot, restricting upgrade capacity to 1 module regardless of total system memory demand.
- DDR5-SDRAM at 4800 MHz requires replacement modules matched to this speed specification; DDR4 or lower-frequency DDR5 variants will not function in this configuration.
- SO-DIMM form factor limits compatible modules to mobile-class memory; full-size UDIMM desktop modules are physically incompatible with the slot dimensions.
- Maximum addressable memory of 24 GB indicates the memory controller supports this ceiling; upgrade modules exceeding this capacity will be rejected by BIOS or operate at reduced capacity.
- Single-slot architecture prevents dual-channel memory configuration, resulting in sequential access to all memory operations through a single data pathway rather than parallel access across 2 channels.
- Replacement operations require complete module removal and reinsertion; no additive upgrade path exists once the slot reaches capacity.
- SO-DIMM modules typically feature retention clips at both ends; improper seating during reinstallation may trigger BIOS error codes or complete system non-responsiveness.
