The MSI Prestige PS42 8M-064 laptop features one SO-DIMM memory slot compatible with DDR4-SDRAM modules operating at 2400 MHz frequency. The upgrade specifications support maximum RAM capacity of 16 GB. Compatible memory modules must conform to SO-DIMM form factor specifications for proper installation in the designated slot. Current memory configuration and upgrade options depend on existing DDR4 capacity installed in the system. Maximum supported memory of 16 GB represents the upgrade ceiling for this Prestige PS series model.

Additional Notes

  • The single SO-DIMM slot configuration prevents dual-channel memory operation, limiting maximum memory bandwidth to approximately 19.2 GB/s instead of the 38.4 GB/s achievable with dual-channel DDR4-2400.
  • Upgrading requires complete replacement of the existing module rather than adding a second stick, meaning the original memory becomes unused.
  • Graphics performance will be constrained by single-channel operation if integrated graphics share system memory, particularly affecting tasks like video editing or light gaming.
  • The 16 GB maximum capacity limitation is likely enforced by chipset constraints or BIOS restrictions rather than physical slot availability.
  • SO-DIMM module compatibility requires verification of operating voltage, with most DDR4 SO-DIMMs standardized at 1.2V but some low-power variants operating at 1.05V.
  • The 2400 MHz frequency represents JEDEC standard DDR4-2400 timing, which typically runs at CL17 latency specifications unless faster XMP profiles are supported and enabled.
  • Memory access latency will be approximately 14.17 nanoseconds at DDR4-2400 CL17, which may bottleneck CPU performance in latency-sensitive applications.
  • Thermal considerations for the single occupied slot may differ from dual-slot configurations, as the module cannot benefit from airflow distribution across multiple DIMMs.
  • Installation requires accessing the bottom panel or keyboard assembly depending on MSI's internal layout for this model, potentially affecting warranty seals.
  • Non-ECC unbuffered memory is implied by the SO-DIMM consumer specification, ruling out error-correcting modules even if physically compatible.
