Additional Notes
- The MSI GS75 Stealth-479 accommodates only 2 SO-DIMM slots, restricting upgrade paths to a maximum of 2 modules regardless of capacity; asymmetrical configurations (mixing different capacities) will function but reduce performance symmetry and dual-channel efficiency.
- DDR4-2666 MHz specification indicates the memory controller operates at this frequency ceiling; installing faster DDR4 modules (3000+ MHz) will downclock to 2666 MHz, eliminating any performance premium from higher-speed components and wasting upgrade investment.
- SO-DIMM form factor requires laptop-specific modules; desktop DDR4 DIMM sticks are physically incompatible due to length and notch positioning, making accidental incompatible purchases likely if sourcing from general retailers.
- 64 GB maximum capacity represents the BIOS/chipset limitation rather than slot limitation; reaching this ceiling requires 2x 32 GB modules, which were significantly more expensive at the time of this model's production and may exhibit reduced compatibility with certain BIOS revisions.
- The 2-slot architecture means any RAM upgrade necessitates removing at least one existing module; if the system shipped with single-channel or mismatched memory, the upgrade path requires replacing rather than supplementing existing modules to achieve dual-channel operation.
- Memory bandwidth potential maxes at approximately 21.3 GB/s (2666 MHz x 64-bit), creating a potential I/O bottleneck for applications performing sustained memory-intensive operations, particularly in workloads requiring rapid data transfer between CPU and RAM.
