Additional Notes

  • The MSI GS65 Stealth-667 utilizes a flipped motherboard design which requires the complete removal of the mainboard from the chassis to access the internal memory slots on the underside.
  • Dual channel memory architecture is only achievable when both slots contain matched modules to maximize available bus bandwidth.
  • Higher frequency modules will automatically downclock to the 2666 MHz processor ceiling due to BIOS chipset limitations.
  • The presence of 2 physical slots restricts the maximum individual module density to 32 GB per bank to reach the total system limit.
  • Thermal pads on the original factory memory may require replacement or careful repositioning during the upgrade process to maintain heat dissipation efficiency.
  • Installing taller high performance heat spreaders on the memory modules may create physical clearance issues with the thin chassis bottom panel.
  • Latency timings default to the slowest installed module if mismatched sticks are used in the secondary slot.
