Additional Notes
- The MSI GS75 9SE-449FR Stealth uses laptop-class SO-DIMM modules rather than desktop DIMMs, restricting upgrade sourcing to mobile-specific memory stock and eliminating cross-compatibility with standard tower configurations.
- DDR4-2666 MHz specification indicates 9th-generation Intel processor pairing; newer DDR4-3200 or faster modules will throttle to 2666 MHz in this system, making premium-speed RAM purchases economically inefficient for this platform.
- Dual SO-DIMM architecture means each module slot carries half the thermal and electrical load; single-slot upgrades to 32 GB will create asymmetric capacity that reduces sustained performance under simultaneous multi-core workloads compared to matched-pair configurations.
- 64 GB total ceiling requires both slots populated with 32 GB modules; upgrading beyond the factory configuration demands removal and replacement of existing memory rather than population of empty slots, reducing the margin for component damage during installation.
- SO-DIMM form factor occupies constrained real estate beneath the keyboard deck; thermal management around memory modules may be limited by heatsink geometry, affecting sustained-boost behavior if aftermarket modules feature taller heat spreaders than OEM components.
- Memory frequency locked at 2666 MHz prevents BIOS-level overclocking adjustments; performance ceiling remains fixed regardless of upgraded module specifications or timings, eliminating frequency-based tuning as a optimization avenue.
