64GB DDR5 6400 ECC RDIMM Server Module

This 64GB DDR5 module operates at 6400MHz with PC5-51200 bandwidth and CL32 latency. It uses a 288-pin registered DIMM form factor with 2Rx4 organisation and on-die ECC for data integrity. The module runs at the standard 1.10V DDR5 voltage and uses Micron chipset components without a heat spreader.

Suited for registered ECC server slots only

This module fits servers and workstations that require registered ECC DDR5 RDIMMs with 2Rx4 density. It will not work in desktop boards that accept only unbuffered non-ECC UDIMMs. Systems needing a heat spreader for thermal management or a different rank configuration should look at other modules.

Registered ECC with 2Rx4 rank decides compatibility

The single specification that determines fit is the registered ECC RDIMM design combined with 2Rx4 rank organisation. Your system memory controller and BIOS must explicitly support registered ECC DDR5 at this rank layout; otherwise the module will not post or will run in a reduced mode.

Questions sur cet article

How do I verify the 64GB DDR5 6400 ECC RDIMM is running at the correct speed and latency after installation?

Enter the system BIOS or use a hardware monitoring tool to confirm the module reports 6400 MT/s, CAS latency 32, and 1.10 V operation.

What comes in the box and what must I purchase separately for this 288-pin DDR5 RDIMM upgrade?

The box contains one 64GB 2Rx4 ECC RDIMM module; no heat spreader or additional cables are included, and no separate components are required for installation.

Which capacity and rank option should I choose when the product lists 64GB 2Rx4 as the only configuration?

The listing provides a single 64GB 2Rx4 module; select this version when your server or workstation requires one 64GB registered DIMM with Micron chipset compatibility.
