ASUS-Compatible DDR4 ECC RDIMM

This 16GB registered module is built for ASUS server motherboards that require ECC DDR4 memory. It targets administrators and IT professionals who need reliable, error-correcting capacity for mission-critical workloads. The single-rank 1Rx4 organisation and 1.2V operation suit dense multi-slot configurations where stability is paramount.

Single-module package with validated compatibility

The kit contains one 16GB stick tested for ASUS server boards, removing guesswork when populating empty DIMM slots. Major OEM chips from Samsung, Micron or Hynix are used, and every unit undergoes stress testing under load before shipping. No heat spreader is fitted, so airflow in compact chassis remains unobstructed.

16GB at 2933 MT/s with CL21 latency

Registered buffering and ECC protect data integrity across large datasets, virtualisation hosts and database engines. The PC4-23400 rating delivers ample bandwidth for typical server tasks, while the single 288-pin module leaves room for further expansion up to the platform limit. Workloads demanding higher per-module density or faster clock rates will exceed what this stick provides.

Questions about this item

Does the 1Rx4 ECC RDIMM need any firmware updates or periodic reseating in an ASUS server?

The module is built with major OEM chips and rigorously stress tested; no firmware updates or scheduled reseating are required after installation.

What limits sustained throughput on this CL21 DDR4 2933 registered stick?

The CAS latency of 21 cycles at 2933 MT/s sets the primary timing ceiling for continuous data transfer.

How much heat and noise does the 1.2 V stick produce when running all day?

Operating at 1.2 V without a heat spreader keeps thermal output low, and the module adds no moving parts or audible noise.
