NEMIX RAM
16 GB DDR4-2933 ECC registered DIMM with CL21 latency and 1.2 V operation for compatible Micron servers
This 16 GB DDR4 2933 module is a registered ECC RDIMM built for Micron server and workstation platforms. It targets administrators who need validated, single-rank memory to expand capacity in mission-critical systems.
The package contains one 288-pin stick rated at CL21 and 1.2 V. Because it is unbuffered only in the sense of being registered, the module adds error correction and signal buffering without extra cooling hardware, keeping installation straightforward in dense chassis.
The stick comfortably handles typical virtualization, database and file-service workloads that fit within a single rank per channel. It runs out when a workload demands higher per-module density or faster data rates than DDR4 2933 provides.

The modules are built with ECC and registered design for server reliability, and the supplier provides a lifetime replacement warranty, so no scheduled replacement is required under normal use.
The CL21 latency and 1.2 V operation define the electrical envelope; sustained full-load throughput is capped by the 2933 MT/s data rate and single-rank 1Rx8 organisation.
With no heat spreader and a low 1.2 V supply, the module generates minimal heat and is completely silent, relying on chassis airflow for cooling.
