16GB DDR4 ECC RDIMM for Supermicro servers

This 16GB DDR4 2400MHz ECC Registered DIMM is built for Supermicro server platforms that require registered memory with error correction. The 2Rx4 dual-rank organisation and CL17 latency suit workloads needing data integrity and stable throughput. It operates at the standard 1.2V DDR4 voltage.

Supermicro certification and Samsung chipset

The module carries Supermicro Certified MEM-DR416L-SL04-ER24 validation and uses Samsung M393A2G40EB1-CRC components. That certification means the DIMM has been qualified for compatible Supermicro systems, reducing the risk of POST failures or memory training errors. Every unit undergoes quality assurance testing before shipment.

16GB capacity headroom and limits

A single 16GB stick adds substantial capacity to a registered channel, supporting virtualisation hosts, database buffers and multi-user applications. The dual-rank design helps populate channels efficiently, but a single module cannot enable multi-channel bandwidth on its own. Systems needing more than 16GB per channel or higher memory speeds will require additional modules or a different specification.

Questions about this item

Will the Samsung chipset or registered ECC circuitry on this 16GB DDR4 2400MHz module require any scheduled replacement?

No, the Samsung chipset and registered ECC circuitry are solid-state components with no moving parts, so they do not need scheduled replacement under normal server operation.

What limit appears first when this 2Rx4 registered DIMM runs at full 2400MHz speed continuously?

The memory controller’s maximum supported rank count per channel is reached before bandwidth or thermal limits, because each 2Rx4 module presents two ranks to the controller.

How much heat and power does a single 1.2V 16GB RDIMM add when the server runs all day?

At the standard 1.2V DDR4 voltage the module draws only a few watts, adding minimal heat that typical server airflow handles without extra cooling.
