16 GB ECC RDIMM for DDR4 servers

This 16 GB registered DIMM uses Micron DDR4-2666 chips on a 288-pin PCB. It targets administrators who need error-correcting memory for database hosts, virtualisation clusters or HPC nodes. The module carries the PC4-21300 speed rating and is sold in new condition.

Thermals noise and power in standard operation

Registered DDR4 RDIMMs run passively and produce no audible noise. Power draw stays within the JEDEC DDR4 voltage envelope during typical server workloads. System airflow across the DIMM slots provides sufficient cooling without extra fan headers.
