A-Tech 32GB DDR4 2133 ECC RDIMM CL15 1.2V 2Rx4 Server Memory

32GB DDR4 2133 ECC RDIMM Server Memory

This 32GB DDR4 2133 registered ECC module is built for servers and workstations that require error-correcting memory. It runs at 1.20V with CL15 latency and uses a 2Rx4 organisation on a 288-pin DIMM. The stick is a direct replacement for the Crucial CT32G4RFD4213 part number.

Capacity and headroom for virtualised workloads

A single 32GB module lets a compatible platform reach higher total memory without filling every slot, which is useful for virtualisation hosts and database servers. The registered design adds a clock cycle of buffering, so very large memory arrays remain stable, but the 2133 MT/s data rate will limit throughput on newer CPU generations that expect faster memory.

Registered DIMM fit and system requirements

The module needs a motherboard that supports DDR4 registered ECC DIMMs and cannot be used in consumer desktop boards that accept only unbuffered memory. It occupies one 288-pin slot and draws standard 1.2V power, leaving other slots free for further expansion. Buyers who need non-ECC or unbuffered memory for a standard PC should look elsewhere.
