MSI Prestige PS42 8RB-059 RAM upgrade specifications

The MSI Prestige PS series model PS42 8RB-059 contains one SO-DIMM slot for DDR4-SDRAM memory upgrade. The laptop supports maximum RAM capacity of 16 GB at 2400 MHz frequency. Compatible memory modules utilize the SO-DIMM form factor specifications standard for ultraportable notebook configurations. Upgrade specifications indicate single-channel memory architecture with DDR4 technology for enhanced system performance and multitasking capabilities.

Additional Notes

• Single channel memory configuration prevents the processor from utilizing dual channel bandwidth benefits, resulting in lower memory throughput for integrated graphics and data intensive tasks.
• Upgrading the system requires the removal and replacement of the existing module because the motherboard lacks a secondary vacant slot.
• The 2400 MHz clock speed limit dictates that installing higher frequency modules like 3200 MHz will result in the hardware downclocking to match the system bus constraint.
• Exceeding the 16 GB capacity threshold remains impossible due to firmware limitations in the BIOS regardless of available high capacity SO-DIMM modules.
• Accessing the memory slot requires total disassembly of the chassis bottom plate and potentially the removal of the cooling assembly as the motherboard is often flipped in this specific ultra portable design.
• Latency performance depends entirely on the CAS latency rating of the single installed module since the system cannot average timings across multiple sticks.
• Thermal throttling may occur during extended high load periods because the compact Prestige chassis lacks dedicated airflow channels specifically for the primary memory module.
• Mismatching voltage requirements between the original Low Voltage DDR4 and standard DDR4 could lead to boot failures or system instability.
