MSI Prestige PS42 8RC-019CZ Modern RAM upgrade specifications

MSI Prestige PS series PS42 8RC-019CZ Modern laptop features one SO-DIMM memory slot supporting DDR4-SDRAM upgrade capacity. Maximum RAM compatible with specifications reaches 16 GB at 2400 MHz frequency. Memory upgrade utilizes SO-DIMM form factor for replacement or expansion. Existing slot allows single memory module installation meeting manufacturer specifications for enhanced system performance.

Additional Notes

• The MSI PS42 8RC-019CZ Modern features a single memory slot configuration, preventing dual-channel operation and limiting memory bandwidth to approximately 19.2 GB/s compared to 38.4 GB/s achievable in dual-channel systems.
• Integrated graphics and CPU share the available memory bandwidth, creating potential bottlenecks during simultaneous processing and rendering tasks.
• The 16 GB capacity ceiling restricts expandability for users anticipating workload growth beyond mid-range multitasking and content creation requirements.
• DDR4-2400 represents the baseline JEDEC standard speed, operating at CAS latencies typically between 15 and 17 cycles, resulting in absolute latency around 12.5 nanoseconds.
• Higher frequency modules rated at 2666 MHz or 3200 MHz will downclock to 2400 MHz due to chipset or CPU memory controller limitations in 8th generation Intel mobile platforms.
• The single SO-DIMM slot necessitates complete module replacement rather than incremental capacity addition when upgrading from factory-installed memory.
• Non-ECC unbuffered modules remain the only compatible option, as SO-DIMM form factor and consumer-grade chipsets exclude registered or error-correcting configurations.
• Operating voltage standards for DDR4-2400 SO-DIMM modules specify 1.2V, ensuring compatibility across manufacturers while maintaining thermal efficiency in compact chassis designs.
• Memory upgrades typically preserve warranty coverage when performed without chassis damage, though verification of regional warranty terms remains advisable before disassembly.
• The absence of a secondary slot eliminates failover redundancy, meaning module failure results in complete system inoperability until replacement.
