Capacity 64GB

  • ECC registered design protects data integrity in servers
  • 64GB single module expands capacity for virtualised workloads
  • DDR5 5600 speed with CL46 latency accelerates throughput
  • 1V operation reduces power draw in dense configurations
  • Validated for Lenovo ThinkAgile HX and MX series

Server ECC RDIMM Upgrade

This 64GB DDR5 module is an ECC registered DIMM built for Lenovo ThinkAgile HX and MX series servers. It targets administrators who need error-correcting memory for virtualisation hosts or storage nodes. Standard desktop boards cannot use this registered design, and it must not be mixed with unbuffered or load-reduced DIMMs.

64GB at DDR5 5600 CL46

A single rank-2Rx4 stick delivers 64GB at 5600 MT/s with CAS latency 46 and 1.1V operation. The capacity suits memory-intensive workloads such as large databases or container clusters, while the JEDEC-standard timing provides stability over raw speed. Systems requiring higher bandwidth per channel or lower latency will reach the limits of this specification.

288-Pin Registered Form Factor

The 288-pin RDIMM fits the ThinkAgile HX630 V3, HX650 V3, MX630 V3, MX650 V3 and VX630 V3 memory slots without a heat spreader. Registered buffering reduces electrical load on the server memory controller, freeing headroom for additional modules. Builds that require unbuffered ECC or consumer SO-DIMM layouts cannot accept this module.

Questions about this item

Will the OWC 64GB DDR5 5600 CL46 ECC Registered RDIMM work alongside existing DDR5 5600 modules in my Lenovo ThinkAgile HX630 V3?

Yes, it will operate with other DDR5 5600 ECC Registered DIMMs of the same voltage and rank configuration; mixing with unbuffered or load-reduced memory is not supported.

How can I verify the OWC 64GB DDR5 5600 module is running at 5600MHz CL46 after installation?

Check the system BIOS or UEFI memory information screen; it should report 5600 MT/s, CAS latency 46, 1.1V and ECC Registered status for the new DIMM.

Does the OWC 64GB DDR5 5600 CL46 2Rx4 RDIMM ship alone or with any accessories?

The upgrade consists of a single 64GB DDR5 5600 PC5-44800 CL46 2Rx4 288-pin 1.1V ECC Registered DIMM; no cables, tools or extra brackets are included.
