MSI Prestige PS42 8M-238AU RAM upgrade specifications

The MSI Prestige PS42 8M-238AU contains DDR4-SDRAM memory configured in a single SO-DIMM slot. The laptop supports maximum RAM capacity of 16 GB with compatible memory operating at 2400 MHz frequency. Upgrade specifications indicate SO-DIMM form factor memory modules are required for this model. The PS42 8M-238AU memory slots allow for RAM expansion to reach the maximum supported capacity through compatible DDR4-SDRAM modules.

Additional Notes

• Single SO-DIMM slot configuration limits concurrent memory to 1 module, eliminating dual-channel architecture benefits and forcing single-channel operation with associated 5-15% performance penalty versus dual-channel setups.
• 16 GB maximum capacity ceiling means upgrade path terminates at single 16 GB module, leaving no headroom for future expansion beyond this threshold.
• 2400 MHz DDR4 support indicates 8th-generation Intel processor compatibility (Kaby Lake Refresh era), establishing hard compatibility boundary for any CPU upgrade attempts.
• SO-DIMM form factor is standard for ultrabook/thin laptop designs, confirming tight internal chassis constraints that preclude larger desktop DDR4 modules or alternative memory technologies.
• Soldered CPU and chipset configurations are typical in this product segment, meaning processor replacement is not feasible through standard service procedures and would void manufacturer warranty.
• Single memory slot combined with 16 GB maximum capacity creates scenario where stock configuration likely shipped with 8 GB module, leaving room for one upgrade to 16 GB without requiring removal of existing memory.
• DDR4-2400 operates at lower speed tier than modern DDR4-3200 standards, indicating this platform cannot leverage performance gains from newer memory without confirmation of BIOS support for memory speed overclocking.
