Server-grade DDR5 ECC RDIMM

This 16 GB registered DIMM runs at DDR5 6400 with a CAS latency of 52 and operates at 1.1 V. It uses a 1Rx8 organisation and a 288-pin form factor for compatible server platforms. The module is built with major OEM chips from Samsung, Micron or Hynix. It is intended for servers that require ECC registered memory and is not suitable for standard PC computers.

Sustained throughput for multi-core workloads

The registered buffer reduces electrical load on the memory controller, helping stability when all channels are populated under continuous demand. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 6400 MT/s data rate and CL52 timing deliver consistent bandwidth for virtualisation, databases and scientific processing. Performance scales with the number of populated slots and the platform memory controller.

Registered design demands compatible motherboard

The 288-pin RDIMM keying fits only DDR5 server boards that support registered ECC modules. A 1Rx8 rank layout allows higher total capacity per channel compared to dual-rank alternatives. The 1.1 V operating voltage matches the DDR5 standard for lower power draw at speed. Buyers needing non-ECC unbuffered memory for workstations or consumer desktops should select a different module type.

Questions about this item

How much power does the 1.1V DDR5 6400MHz module draw under sustained server load?

The module operates at 1.1V, which is the standard voltage for DDR5 RDIMMs; actual power draw varies with workload and platform configuration.

What motherboard features are required to run this 288-pin ECC RDIMM?

A server motherboard with DDR5 RDIMM slots, registered ECC support, and a memory controller qualified for PC5-51200 speeds is required.

Will this 1Rx8 PC5-51200 CL52 module work in a system that also has slower DDR5 RDIMMs installed?

All DDR5 RDIMMs in a channel run at the speed of the slowest module; mixing different speeds is possible but the faster kit will downclock to match.
