MSI Workstation WS75 10TL-494CA RAM upgrade specifications

MSI WS75 10TL-494CA workstation memory upgrade specifications detail DDR4-SDRAM compatibility with 2x SO-DIMM slots supporting maximum capacity of 64 GB total RAM. The laptop accepts DDR4 memory modules operating at 2666 MHz frequency. Upgrade configurations accommodate single or dual module installations within SO-DIMM form factor constraints. Compatible memory modules must match DDR4-SDRAM specifications and 2666 MHz frequency requirements for optimal workstation performance and stability.

Additional Notes

• The MSI WS75 10TL-494CA workstation accepts PC4-21300 modules, which directly corresponds to the 2666 MHz specification through the standard calculation of effective MHz multiplied by 8 bytes per transfer.
• DDR4-SDRAM modules with speeds exceeding 2666 MHz will downclock to match the system's maximum supported frequency, potentially negating the cost premium of higher-speed memory.
• The 2 SO-DIMM slot configuration requires a 32 GB module in each position to achieve the 64 GB maximum capacity, as no single SO-DIMM module currently exceeds 32 GB density.
• Mixing different capacity modules between slots remains technically functional but eliminates dual-channel memory interleaving for the unpaired portion, reducing effective bandwidth for memory-intensive workloads.
• SO-DIMM form factor measures 67.6 mm in length compared to standard DIMM's 133.35 mm, making desktop memory modules physically incompatible regardless of electrical specifications.
• The absence of ECC designation in the specifications indicates non-parity memory support, meaning ECC SO-DIMM modules will function but operate without error correction capabilities.
• Dual-channel architecture across the 2 slots provides a theoretical maximum bandwidth of 42.6 GB/s when both channels operate simultaneously with matched modules at 2666 MHz.
• CAS latency values between CL15 and CL19 at 2666 MHz offer minimal real-world performance variance in most applications, typically under 3 percent in memory-sensitive benchmarks.
• User-accessible memory slots in this model class typically void warranty only if physical damage occurs during installation, though policies vary by region and retailer.
• Operating voltage for DDR4 SO-DIMM standardizes at 1.2V, with low-voltage variants at 1.05V offering negligible battery life improvement in mobile workstations due to overall power consumption distribution.
