Additional Notes
- The presence of a single SO-DIMM slot alongside permanent on-board memory prevents a symmetric dual-channel configuration when replacing the module with a higher capacity than the factory-soldered portion.
- Memory bandwidth is constrained to the 2400 MHz frequency even if a higher-rated module is installed because the system bus will downclock the faster component to match the slowest internal link.
- Total addressable memory is physically capped by the motherboard firmware, meaning the ASUS Vivobook S512FA-DB71 will ignore capacities provided by 16 GB or 32 GB modules despite the electrical compatibility of the DDR4 interface.
- Upgrading the removable stick involves a high risk of losing dual-channel performance for the portion of the RAM that exceeds the soldered capacity, resulting in asynchronous memory access patterns.
- Thermal management remains a factor during installation as the proximity of the on-board chips to the expansion slot limits the use of modules with thick integrated heat spreaders.
- System stability depends on matching the CAS latency of the soldered chips since the BIOS lacks manual timing adjustments to reconcile discrepancies between mixed memory vendors.
