Server memory module

This 16GB DDR3 1866 MHz ECC registered DIMM is built for servers and workstations that require registered memory. It uses a 240-pin form factor and operates at standard 1.5V DDR3 voltage. It is not compatible with desktop or laptop computers that use unbuffered memory.

Capacity and workload fit

The single 16GB module adds substantial memory headroom for virtualisation, database caching or multi-user application servers. Dual-rank x4 organisation helps populate memory channels efficiently on supported platforms. Systems limited to lower-density modules or fewer DIMM slots may not recognise the full capacity.

Thermals and power

Standard 1.5V operation keeps power draw predictable within DDR3 server specifications. Registered buffering reduces electrical load on the memory controller, aiding stability in fully populated configurations. Passive cooling relies on chassis airflow; no active cooling is included on the module.

Questions about this item

Will this DDR3 1866 ECC RDIMM downclock automatically if installed alongside slower DDR3 modules in the same server?

The module operates at DDR3 1866 with CL13 latency at 1.5V; when mixed with slower DDR3 DIMMs the system typically runs all memory at the lowest common speed and timing.

How can I verify the 16GB ECC RDIMM is recognised and running at 1866 MHz after installation?

Check the BIOS memory summary or OS tools such as dmidecode to confirm 16 GB capacity, ECC Registered type, 1866 MT/s data rate and 1.5V operating voltage.

Does the 240-pin 2Rx4 RDIMM ship alone, or are heat spreaders or extra cables included?

The box contains a single 16GB DDR3 1866 ECC Registered DIMM (2Rx4, 240-pin) only; no heat spreaders, cables or additional accessories are supplied.
