  • 2 V operation reduces power draw per module
  • Single-rank 1Rx4 layout optimises density for 16 GB capacity

Server-grade ECC RDIMM

This 16 GB DDR4 2666 registered DIMM adds error-correcting capacity to compatible Micron-based servers and workstations. It targets IT professionals who need validated stability for mission-critical workloads. The single-rank 1Rx4 organisation keeps electrical loading low on populated channels.

Registered buffer and 1.2 V operation

The on-module register reduces signal load on the memory controller, allowing larger populations per channel without timing compromise. Standard 1.2 V DDR4 voltage fits existing server power budgets and requires no special BIOS tuning. ECC circuitry corrects single-bit errors before they reach the operating system.

16 GB per module headroom

One 288-pin RDIMM delivers 16 GB at CL19 latency, suited to virtualisation hosts and database nodes that benefit from registered ECC integrity. Capacity scales by adding identical modules to free slots; mixed-rank or unbuffered DIMMs are not supported on the same channel.

Questions about this item

Will the CL19 latency become a bottleneck under sustained server workloads?

CL19 is the rated CAS latency for this DDR4 2666 module; sustained throughput depends on the platform memory controller and rank configuration.

Does the registered design and 1.20 V operation keep thermals manageable in a fully populated chassis?

The 1Rx4 registered RDIMM runs at standard 1.20 V without a heat spreader; airflow across the DIMM slots is the primary cooling path.

Must the motherboard support ECC RDIMM and 288-pin DDR4 slots to use this module?

Yes, the module requires a server or workstation board with DDR4 RDIMM slots and ECC enabled in the BIOS.
