Additional Notes
- Single slot architecture prevents dual channel memory configurations and limits data throughput to a single 64 bit bus.
- The absence of secondary slots necessitates the replacement of the existing module to facilitate any increase in capacity.
- Internal hardware access requires the removal of the entire base panel which often involves piercing a factory seal sticker over a screw hole.
- Motherboard hardware limits memory expansion to 16 GB regardless of larger capacity SO-DIMM availability on the market.
- Installing memory modules with frequencies higher than 2400 MHz results in automatic downclocking to match the system bus speed.
- The compact chassis design requires low profile SO-DIMM modules to ensure proper fitment and heat dissipation within the enclosure.
- Memory bandwidth acts as the primary performance ceiling for integrated graphical tasks due to the lack of dedicated parallel memory paths.
