Supermicro Certified 16GB DDR4 RDIMM

This 16GB DDR4 2666MHz module is built for servers and workstations that require registered ECC memory. The dual-rank 2Rx4 organisation and Samsung chipset provide the density and error correction needed for multi-socket platforms and virtualisation hosts.

Sustained load behaviour with CL19 latency

At the rated PC4-21300 speed and CL19 timings the module maintains consistent throughput during extended compute jobs. Registered buffering reduces electrical load on the memory controller, allowing larger populations per channel without signal degradation over long runs.

Thermals noise and power at 1.20V

Operating at the standard 1.20V DDR4 voltage keeps power draw low and heat output minimal inside dense chassis. Passive cooling via system airflow is sufficient; no active fan on the module means zero acoustic contribution during normal operation.

Questions about this item

How much power does the 1.20V DDR4 2666MHz module draw when running continuously?

The module operates at the standard DDR4 voltage of 1.20V, which helps limit heat output and power draw during all-day server workloads.

What motherboard slot and memory type must my system already support for this 288-pin RDIMM to work?

Your motherboard needs a DDR4 RDIMM slot that accepts 288-pin registered ECC modules and supports the PC4-21300 speed grade.

Can I mix this 2Rx4 Samsung-based stick with older single-rank DDR4 ECC modules in the same server?

Mixing ranks is possible if the platform allows it, but population rules vary by motherboard; check the system manual for supported rank combinations per channel.
