  • Dual-rank 2Rx8 organisation increases memory bandwidth
  • 20 V operation meets standard DDR4 voltage requirements

Server DDR4 ECC RDIMM

This 16 GB registered DIMM adds error-correcting memory to compatible DDR4 servers and workstations. It targets administrators who need data integrity for virtualisation, databases or compute clusters. The module is not suitable for desktop or laptop platforms that accept only unbuffered memory.

Registered 288-pin integration

The stick plugs into a 288-pin DDR4 RDIMM slot and requires a platform that supports registered, dual-rank modules. The register buffers address and control signals, reducing electrical load on the memory controller and allowing higher total system capacities. No extra cooling or power connectors are needed beyond the slot itself.

16 GB headroom at 2933 MHz

Running at 2933 MHz with CL21 latency and 1.2 V, the module handles typical multi-threaded workloads and moderate virtual machine densities. Capacity limits appear when applications demand more than 16 GB per channel or when the platform's maximum supported memory per socket is reached.

Questions about this item

At what CAS latency does the CL21 timing become the limiting factor under sustained load?

The module operates at CL21 CAS latency; sustained throughput will be bound by this timing figure combined with the 2933 MT/s data rate.

What are the thermal and acoustic characteristics when the DIMM runs continuously at 1.2 V?

The registered ECC DIMM runs at the standard 1.2 V DDR4 voltage and has no active cooling; it relies on system airflow, so heat output and noise depend entirely on the server chassis design.

Which existing hardware must the system provide for this registered ECC module to function?

The motherboard must support DDR4 registered ECC RDIMMs in a 288-pin slot and accept dual-rank x8 modules at 2933 MT/s.
