NEMIX RAM 32GB DDR4 2933 ECC RDIMM Dell PowerEdge C6420

Dell PowerEdge C6420 server module

This 32GB DDR4 ECC registered DIMM is built for the Dell PowerEdge C6420 server platform. It targets administrators who need to expand memory capacity in compatible Dell systems without replacing existing modules. The single-module design suits incremental upgrades in multi-slot configurations. Buyers who want non-ECC desktop memory or unbuffered DIMMs should look elsewhere.

Registered ECC with CL21 latency

The module runs at DDR4 2933 speed (PC4-23400) with a CAS latency of 21 and operates at 1.2V. Its 2Rx4 rank organisation and registered buffer ensure signal integrity on heavily populated server motherboards. ECC protection corrects single-bit errors to maintain data integrity in critical workloads. Systems that require unregistered or lower-density modules cannot use this part.

Steady throughput under continuous load

Registered buffering and ECC overhead keep latency consistent during sustained read-write cycles typical of virtualisation and database tasks. The 1.2V operating voltage limits thermal output when all memory channels are populated. Without a heat spreader, adequate chassis airflow is necessary to maintain rated performance over long periods. Workloads that exceed the single 32GB capacity will need additional modules.
