64GB DDR4-2666 LRDIMM for servers

This 64GB DDR4-2666 LRDIMM is built for HP-compatible servers that need maximum memory capacity per slot. It targets administrators who run virtualisation hosts, in-memory databases or heavy application workloads and want to extend the life of existing rack infrastructure without replacing hardware.

4Rx4 Load-Reduced ECC at 1.2V

The module uses a 4Rx4 Load-Reduced organisation with ECC and operates at 1.2V, reducing electrical load on the memory bus so dense configurations remain stable. Its 288-pin DDR4 form factor fits standard server DIMM slots, and the major-brand DRAM ensures compatibility with OEM service contracts and qualified-vendor lists.

Replaces lower-capacity RDIMMs or LRDIMMs

This part replaces smaller RDIMMs or LRDIMMs when the platform supports Load-Reduced modules and the workload demands more capacity per channel. The jump is worth it when swapping and paging appear, when virtual-machine density is capped by memory slots, or when the HP 838085-B21 equivalent is specified for the server model.

Questions about this item

What speed does the DDR4-2666 interface actually run at in this module?

The module operates at 2666 MT/s, labelled PC4-21300, with a CAS latency of CL15 at 1.2 V.

Will this 288-pin LRDIMM fit in my server's DIMM slots?

It uses the standard 288-pin DDR4 LRDIMM form factor and requires slots that support load-reduced registered memory.

How do I install this 4Rx4 ECC module and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that all 64 GB are detected and ECC is enabled.
