MSI Prestige PS42 8M-480FR RAM upgrade specifications

The MSI Prestige PS42 8M-480FR features DDR4-SDRAM memory upgradeable through one SO-DIMM slot. Compatible RAM specifications include DDR4 modules operating at 2400 MHz frequency. The laptop supports maximum memory capacity of 16 GB, requiring SO-DIMM form factor modules for upgrade compatibility. Memory expansion enables enhanced multitasking and performance optimization for the PS series ultrabook platform.

Additional Notes

• The MSI PS42 8M-480FR features 1 soldered memory module alongside the single SO-DIMM slot, creating a dual-channel configuration when populated with matching specifications.
• DDR4-2400 represents the JEDEC standard speed, while faster modules rated at 2666 MHz or 3200 MHz will downclock automatically to 2400 MHz due to chipset limitations in 8th generation Intel platforms.
• The 16 GB maximum capacity constraint stems from the Intel Core 8th generation mobile processor's integrated memory controller specifications, not the physical slot itself.
• Accessing the SO-DIMM slot requires complete bottom panel removal, as the memory compartment lacks a dedicated service door on this chassis design.
• Installing a 16 GB module reaches the platform ceiling immediately, eliminating future expansion possibilities beyond this single upgrade.
• Operating voltage must conform to DDR4 standard of 1.2V, as low-voltage variants designed for different specifications may cause POST failures or system instability.
• CAS latency variations between CL15, CL17, and CL19 modules produce negligible real-world performance differences at the 2400 MHz frequency ceiling.
• The SO-DIMM form factor measures 67.6mm in length compared to standard DIMM modules, making desktop memory physically incompatible regardless of electrical specifications.
• Mixing modules with different densities or ranks may force single-channel operation, effectively halving memory bandwidth from the theoretical 38.4 GB/s maximum.
• Thermal constraints within the slim chassis design favor modules without tall heatspreaders, as clearance between the memory slot and bottom panel measures less than 5mm.
