Additional Notes

  • The MSI GS65 Stealth-422 supports only 2 SO-DIMM slots, meaning RAM upgrades require replacement of existing modules rather than addition of supplementary sticks, necessitating retention or separate storage of original memory if future rollback becomes necessary.
  • DDR4-2666 MHz specification indicates the memory controller operates at a fixed frequency; faster DDR4 modules (3000 MHz, 3200 MHz) will downclock automatically to 2666 MHz, eliminating performance advantage from premium memory pricing.
  • 64 GB maximum capacity creates a practical ceiling at 32 GB per SO-DIMM modules; availability of 32 GB SO-DIMM units remains limited compared to standard DIMM options, potentially increasing cost per gigabyte and reducing vendor selection.
  • SO-DIMM form factor requires compact module design; this restricts heatspreader options and may affect thermal performance under sustained load compared to full-size DIMM heatspreaders, particularly in gaming workloads with sustained memory bandwidth utilization.
  • The 2-slot configuration creates single points of failure; failure of one module results in complete system inability to access memory from that slot, whereas 4-slot systems permit continued operation with degraded capacity.
  • DDR4-2666 memory speed represents the lower tier of modern DDR4 standards; this may indicate the memory controller predates higher-speed optimization, affecting bandwidth delivery to CPU cache and GPU in memory-intensive gaming scenarios.
