Additional Notes
- The inverted motherboard design of the MSI GS65 9SE-405NL Stealth requires the removal of the entire mainboard to access the underside RAM slots.
- Dual channel mode performance relies on identical module capacities and timings across both available SO-DIMM sockets.
- Installing high speed modules results in an automatic downclock to the 2666 MHz processor ceiling if the system BIOS lacks XMP profile support.
- Thermal pads on existing memory modules may require replacement or repositioning after disassembling the chassis for capacity increases.
- The 64 GB limit indicates compatibility with 32 GB high density modules using 16 Gb die density configurations.
- Latency parity between factory and aftermarket sticks prevents the system from defaulting to the slowest shared JEDEC timing profile.
- Upgrading to the maximum supported capacity doubles the electrical load on the memory controller compared to a single stick configuration.
