Additional Notes
- The MSI Prestige PS42 8RA-274RU Modern contains a single memory slot, meaning maximum capacity expansion is limited to 16 GB total rather than distributed across multiple modules.
- SO-DIMM form factor restricts upgrade options to laptop-specific memory modules; desktop DDR4 DIMM modules cannot be physically installed regardless of electrical compatibility.
- The 2400 MHz frequency specification indicates the system operates at a lower bandwidth tier than contemporary DDR4 standards (3200 MHz or higher), which constrains data throughput to memory-intensive applications such as video editing or large dataset processing.
- Upgrading from the factory configuration to 16 GB requires complete module replacement rather than additive installation, necessitating removal and replacement of the existing memory stick.
- DDR4-2400 memory modules are increasingly difficult to source as manufacturers have shifted production toward higher-frequency variants, potentially extending acquisition lead times for warranty-compliant replacements.
- The single-slot architecture creates a single point of failure for system memory; if the installed module fails, the system becomes non-functional until replacement occurs.
- Mixed-capacity configurations are not applicable; the system cannot accommodate simultaneous operation of memory modules at different capacities or frequencies due to the single-slot limitation.
