Server DDR4 ECC RDIMM module

This A-Tech module is a 16GB DDR4 2133MHz PC4-17000 CL15 registered DIMM with ECC. It is built for servers and workstations that require error-correcting memory. The stick runs at the standard 1.2V and uses a 2Rx4 organisation.

Fits DDR4 RDIMM slots on supported platforms

The 288-pin DIMM plugs into registered DDR4 slots that accept ECC RDIMMs. It replaces several Kingston part numbers including D2G72M151 and KVR21R15D4/16. The single-module design leaves other slots free for further capacity expansion.

Suits admins upgrading compatible servers

Buyers who need ECC registered memory for a verified platform will find this module matches the listed specifications. Builders whose systems require unbuffered UDIMMs, different speeds, or non-ECC memory should look at something else.

Questions about this item

How many ranks does the 16GB module use?

The module is built as a dual-rank 2Rx4 configuration, so each 16GB stick presents two ranks to the memory controller.

What is the typical power draw of a registered ECC DIMM running continuously at 1.2V?

At the standard 1.2V DDR4 voltage a registered ECC DIMM of this capacity typically draws only a few watts, keeping heat output low during all-day operation.

Does my server need to support registered ECC memory and 288-pin DDR4 slots?

Yes, the system must accept DDR4 RDIMMs with ECC and have 288-pin DIMM slots; otherwise the module will not function.
