Supermicro Certified 16GB DDR4 ECC RDIMM

This module delivers 16GB of DDR4 memory at 2666MHz with ECC Registered operation for Supermicro server platforms. The single-rank 1Rx4 Samsung organisation and CL19 timing provide dependable throughput for memory-intensive workloads. Supermicro certification confirms the module has passed platform-level validation on target systems.

Who this suits and who should look elsewhere

This part fits administrators expanding or repairing Supermicro servers that require registered DDR4 ECC RDIMMs at 2666MHz. Buyers needing higher capacities, different speeds, unbuffered modules or non-ECC memory should select a module that matches those specifications.

The specification that decides fit

The module is a 288-pin DDR4 RDIMM running at 1.20V with CL19 latency and a Samsung 1Rx4 chipset; only systems that support registered ECC DDR4 at this voltage and pin-out will accept it.

Questions about this item

How much power does this 1.20V DDR4 2666MHz RDIMM draw when running continuously?

The module operates at the standard DDR4 voltage of 1.20V, which keeps power draw low during all-day server workloads.

What motherboard slot is required to install this 288-pin RDIMM?

A DDR4 RDIMM slot with 288 pins is needed; the system must also support ECC registered memory for the module to function.

Can this Supermicro certified 1Rx4 module be mixed with other DDR4 RDIMMs in the same server?

It is a single-rank 1Rx4 design at 2666MHz CL19; mixing ranks or speeds may work but the system will run all modules at the lowest common speed.
