128 GB DDR5-6400 Registered ECC DIMM

This 128 GB DDR5-6400 module delivers registered ECC memory for enterprise servers and workstations that require data integrity at scale. The dual-rank design runs at 6400 MHz with a CAS latency of 52 and operates at 1.10 V. A 288-pin form factor fits standard DDR5 DIMM slots in qualified platforms.

Suited for high-capacity server deployments

IT teams building or expanding memory-heavy database, virtualization or HPC clusters will benefit from the density and error correction. Builders without a server-class motherboard that supports registered DDR5 ECC DIMMs should look elsewhere, as consumer boards cannot use this module.

Fits qualified DDR5 RDIMM slots in server chassis

The module installs directly into 288-pin registered DIMM sockets on compatible server mainboards, requiring no additional cabling or cooling hardware beyond standard airflow. Registered buffering reduces electrical load on the memory controller, freeing headroom for larger memory configurations across multiple channels.

Questions about this item

Will this 288-pin DDR5-6400 module fit and run in a server board that has DDR5 RDIMM slots?

Yes — the module is a 288-pin DDR5-6400 RDIMM, so it installs in any server board with DDR5 RDIMM slots.

Can I mix this ECC Registered 128 GB stick with smaller DDR5 RDIMMs already in my server?

Mixing capacities is possible if the platform supports mixed-population rules, but matching rank, speed and voltage gives the most stable operation.

How do I verify the module is running at 6400 MT/s with CL52 after installation?

Check the BIOS memory information screen or use a tool like dmidecode to confirm 6400 MT/s speed and CL52 latency.
