16 GB DDR4 SoDIMM server memory running at 3200 MHz with CL22 latency and 1.2 V operation
This 16 GB DDR4 module uses the SoDIMM 260-pin form factor to fit space-constrained server and workstation boards. Single-rank x8 organisation and unbuffered signalling keep the electrical load light for dense memory populations. Intel XMP 2.0 support allows the rated 3200 MHz speed to be enabled through the platform BIOS. Non-ECC operation suits applications that do not require error correction.
The module runs at 1.2 V, reducing power draw and heat output in multi-DIMM configurations. CL22 latency at 3200 MHz delivers responsive access times without aggressive timing voltages. Passive green and black PCB construction relies on chassis airflow rather than active cooling. Unbuffered design avoids the extra register power consumed by registered alternatives.
Replacing 4 GB or 8 GB DDR4 SoDIMMs with this 16 GB unit doubles or quadruples per-slot capacity for virtualization hosts or database nodes. The jump is worthwhile when the platform supports 3200 MHz and the workload benefits from larger memory footprints. Systems limited to lower speeds or lacking XMP 2.0 will not realise the full frequency gain. Buyers needing ECC data integrity should select a different module.

Align the notch with the slot key, insert at a slight angle, then press down until both side clips click; the step often missed is fully seating the module so the clips engage automatically.
No scheduled maintenance is required; replacement is only needed if a memory test reports errors or capacity must be increased beyond 16GB.
The CL22 latency at 1.2V unbuffered operation is the first constraint; thermal throttling may follow if system airflow is insufficient.
