Additional Notes
- Dual channel architecture is achievable by installing two identical memory modules to increase memory bandwidth compared to single stick configurations.
- The presence of 2 physical slots ensures that factory memory is replaceable and allows for a symmetrical 16 plus 16 arrangement for maximum capacity.
- Installing modules with frequencies higher than 2400 MHz results in automatic downclocking to match the system bus speed limit.
- The SO-DIMM form factor requires 260-pin DDR4 modules and lacks compatibility with desktop DIMM or older DDR3 hardware.
- Maximum memory capacity supports professional virtualization or heavy multitasking workloads beyond standard office use requirements.
- Accessing the memory slots requires removal of the bottom chassis cover which may involve captive screws and plastic clips.
- System stability depends on using non-ECC unbuffered memory as registered or ECC modules will prevent successful POST cycles.
- Lower latency timings on aftermarket kits provide minor performance gains but must operate at 1.2 volts to meet standard motherboard power delivery.
