Additional Notes

  • The inverted motherboard design of the MSI GS75 Stealth-249 necessitates a full teardown of the internal chassis to access the SO-DIMM slots located on the underside of the PCB.
  • Dual channel memory architecture requires installing 2 matched modules to maximize memory bandwidth and prevent CPU performance throttling during high load gaming tasks.
  • System stability depends on using modules that support JEDEC standard timings because the BIOS typically lacks XMP profile support for overclocked memory speeds.
  • Upgrading to the maximum 64 GB capacity limits the motherboard to 2 rank configurations per channel which can increase heat localized around the central processor area.
  • Replacing an individual pre-installed module with a higher capacity stick forces the system into flex mode results in asymmetrical memory operation and reduced data throughput.
  • Physical clearance for memory modules is restricted by the ultra thin chassis profile meaning high profile heat spreaders will interfere with the bottom panel closure.
  • Internal component density requires the use of non-conductive tools and battery disconnection before handling the SO-DIMM slots to avoid short circuiting the surface mounted components.
