Additional Notes
- The motherboard architecture requires a flipped design meaning physical access to the 2 SO-DIMM slots necessitates a full teardown of the MSI GS75 9SG-835RU Stealth to expose the rear side of the PCB.
- Utilizing mismatched latency timings between modules triggers a fallback to the highest common SPD profile which results in increased memory controller stress.
- Installing high performance 3200 MHz modules is possible but the Intel 9th Generation chipset limits actual operating speeds to the 2666 MHz hardware ceiling.
- Reaching the 64 GB maximum capacity involves replacing both pre-installed modules as no unpopulated expansion slots exist for additive upgrades.
- Dual channel bandwidth benefits are only active when both slots contain identical densities while asymmetrical configurations force the system into less efficient flex mode operation.
- Thermal pads on the RAM modules are often required to maintain stability due to the thin chassis profile and proximity to high heat output components.
- Firmware updates are recommended before installing 32 GB modules to ensure full addressable capacity recognition at the BIOS level.
