Server Memory Module

The Crucial CT16G4RFD4213 is a 16GB DDR4 registered DIMM built for servers and workstations that require error-correcting code memory. It suits administrators upgrading multi-socket platforms where data integrity and signal stability across populated channels are mandatory.

DDR4 2133 Interface Limits

The module runs at DDR4 2133 (PC4 17000) with a CAS latency of 15 at 1.20V. Registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel, but the 2133 MT/s ceiling caps throughput compared to faster DDR4 bins available for the same socket.

Capacity and Headroom

A single 16GB 2Rx4 rank delivers substantial capacity per slot, letting a quad-channel kit populate four channels efficiently. Workloads such as virtualisation hosts or in-memory databases benefit from the density, while compute-bound tasks that scale with memory bandwidth will saturate the 2133 MT/s link before exhausting capacity.

Questions about this item

Is this 16GB module sold individually or as part of a multi-channel kit?

The 16GB module is part of a quad-channel kit designed for four-slot population.

What does the 2133 speed rating mean for actual throughput in a server?

DDR4 2133 (PC4 17000) delivers a peak transfer rate of 17000 MB/s per module at 1.20V.

Does the registered ECC design limit the memory standard or voltage used?

The module uses standard DDR4 at 1.20V with CL15 latency; registered ECC operation follows the DDR4 2133 specification.
