MSI Prestige PS42 8RA-022ES RAM upgrade specifications

MSI Prestige PS42 8RA-022ES RAM upgrade specifications detail memory configurations for the laptop model. The system features one SO-DIMM slot supporting DDR4-SDRAM memory modules operating at 2400 MHz frequency. Maximum compatible RAM capacity extends to 16 GB, allowing for a single-module upgrade to enhance overall system performance. The SO-DIMM form factor designates memory compatibility with this specific portable workstation design. Specifications enable users to evaluate upgrade feasibility and memory compatibility requirements for the Prestige PS series notebook.

Additional Notes

• The MSI Prestige PS42 8RA-022ES features a single memory slot configuration, preventing dual-channel operation and reducing memory bandwidth to approximately 19.2 GB/s compared to the 38.4 GB/s available in dual-channel systems.
• Upgrading requires complete replacement of the existing module rather than supplementing it, necessitating removal of the factory-installed RAM regardless of its current capacity.
• The 16 GB ceiling represents a hard limitation of the system's memory controller or BIOS, making configurations beyond this capacity impossible without motherboard replacement.
• DDR4-2400 operates at a CAS latency typically between CL15 and CL17, resulting in true latency between 12.5 and 14.2 nanoseconds depending on module specifications.
• The SO-DIMM form factor measures 67.6 mm in length, requiring physical access to the bottom panel or keyboard assembly depending on the chassis design of this 14-inch ultraportable model.
• Installing higher-frequency modules such as DDR4-2666 or DDR4-3200 will result in automatic downclocking to 2400 MHz, as the system will default to the maximum supported frequency.
• Single-channel architecture creates particular performance constraints in integrated graphics workloads, where GPU and CPU compete for access to the same memory bandwidth.
• The 1.2V standard voltage requirement for DDR4 SO-DIMMs ensures compatibility across manufacturers, though low-voltage variants are unnecessary given DDR4's inherent efficiency compared to DDR3L.
• Non-ECC unbuffered modules are required, as registered or error-correcting memory types remain incompatible with consumer-grade mobile platforms of this class.
• Accessing the memory slot likely requires complete disassembly of the lower chassis cover, as thin-and-light designs typically integrate the RAM under the primary structural components rather than behind dedicated service doors.
