Additional Notes
- The dual channel architecture requires symmetrical module pairing to reach the peak theoretical bandwidth of the DDR5 bus.
- Upgrading the MSI GS77 12UH-057NL Stealth to the maximum capacity necessitates the removal of all existing pre-installed modules due to the lack of unoccupied slots.
- Higher frequency memory kits will downclock to the 4800 MHz baseline if the system firmware lacks XMP profiles for overclocked speeds.
- The 64 GB threshold represents a hardware limitation of the physical trace routing or firmware configuration rather than a limitation of the DDR5 technology itself.
- Physical access to the SO-DIMM slots typically requires the removal of the entire base panel which may involve piercing factory seal stickers in certain regions.
- Low latency timings are more critical for gaming performance stability than raw frequency increases at this specific platform generation.
- DDR5 modules utilize on-die ECC and integrated power management integrated circuits which generate more localized heat compared to older memory standards.
