Additional Notes
- Dual channel architecture requires matching module capacities and timings across both slots to ensure peak memory bandwidth for the MSI GS66 10UH-041AU Stealth.
- Integrated memory controller limitations on 10th Gen processors may downclock 3200 MHz modules to 2933 MHz depending on the specific CPU tier installed.
- Physical installation of 64 GB necessitates the removal of all existing factory modules as no vacant expansion slots remain for incremental additions.
- Maintenance of system stability at high capacities requires modules with JEDEC standard voltages to avoid power delivery mismatches on the logic board.
- Accessing the SO-DIMM slots involves removing the base panel and potentially breaking a factory seal sticker which varies by regional warranty policy.
- Latency performance depends on the use of Unbuffered Non-ECC memory as Registered or ECC modules will prevent the system from POSTing.
- Thermal constraints within the thin chassis design suggest avoiding high profile heat spreaders on replacement RAM to prevent contact with the bottom cover.
