32GB DDR5 6400 ECC Registered RDIMM

This module delivers 32GB of DDR5 server memory at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. It is built for enterprise platforms that require registered ECC RDIMMs and will not function in standard desktop PCs.

Installation and compatibility

The 288-pin RDIMM fits server motherboards qualified for DDR5 6400 registered ECC memory; it cannot be used in unbuffered or non-ECC slots. Verify the platform supports 1Rx4 registered modules before purchase to avoid a non-posting system.

Capacity and headroom

A single 32GB rank provides substantial capacity for virtualisation, database or compute workloads on compatible DDR5 servers. Workloads exceeding this per-slot limit or requiring higher frequencies will need additional modules or a platform supporting faster DDR5 speeds.

Questions about this item

How do I verify the 1Rx4 ECC Registered module is running at 6400 MT/s after installation?

Check the memory speed in your server BIOS or use a tool like dmidecode to confirm 6400 MT/s and CL52 timings at 1.1V.

What comes in the box with this 288-pin DDR5 RDIMM?

The box contains one 32GB DDR5 6400 PC5-51200 1Rx4 ECC Registered RDIMM. No cables or accessories are included.

Should I choose the 1Rx4 32GB version or a dual-rank alternative for my server?

The 1Rx4 32GB module suits platforms that prefer single-rank density per channel; dual-rank options differ in rank structure and are not this part.
