Additional Notes
- The presence of a single SO-DIMM slot alongside permanent on-board memory means that total capacity increases require replacing the existing module rather than adding a second one.
- The ACER Extensa EX215-54-31GM architecture dictates a maximum expansion limit of 8 GB for the removable module to reach the 12 GB ceiling.
- Installing modules with frequencies higher than 2133 MHz will result in automatic downclocking to match the system bus speed.
- Asynchronous dual-channel mode will only function for the capacity portion where the on-board and removable memory sizes match, while the remaining capacity operates in single-channel mode.
- Integrated memory chips are non-serviceable and cannot be replaced or upgraded in the event of hardware failure.
- Accessing the SO-DIMM slot requires the removal of the entire base panel which may involve piercing factory seals depending on regional warranty policies.
- Physical clearance within the chassis restricts compatibility to standard height SO-DIMM modules and precludes the use of thick heat spreaders.
