64GB DDR4 2666MHz ECC LRDIMM Module

This 64GB DDR4 2666MHz ECC LRDIMM module is a compatible replacement for Cisco 15-105084-01 and UCS-ML-X64G4RS-H. It operates at 1.20V with CL19 latency and uses a 4Rx4 rank configuration. The 288-pin DIMM is designed for server and workstation systems requiring registered load-reduced memory.

Suits Cisco UCS upgrades needing 64GB density

This module suits administrators upgrading compatible Cisco UCS servers that accept DDR4 2666MHz ECC LRDIMMs. It is not for systems limited to RDIMM or UDIMM form factors, nor for platforms that cannot address 4Rx4 ranks. Builders needing non-ECC memory or speeds above 2666MHz should look elsewhere.

Single 64GB module handles heavy virtualization

The 64GB capacity provides headroom for dense virtualization, large databases and in-memory analytics on supported platforms. Performance scales with populated channels up to the system's maximum supported memory. Limits appear when the platform's memory controller reaches its rank-per-channel ceiling or total capacity ceiling.

Perguntas sobre este artigo

Does my server need a DDR4 2666 MHz LRDIMM slot to use this 64GB module?

Yes, the module is a DDR4 2666 MHz (PC4-21300) ECC LRDIMM with a 288-pin DIMM form factor and requires a compatible DDR4 LRDIMM slot.

Can I mix this 4Rx4 CL19 1.20V LRDIMM with existing 2Rx4 RDIMMs in the same channel?

No, Load Reduced DIMMs use a different electrical design and rank structure than standard RDIMMs; they cannot be mixed in the same channel.

How do I confirm the 64GB module is running at 2666 MHz with ECC active after installation?

Check the system BIOS or OS memory report: it should show 64 GB, 2666 MT/s, CL19, 1.2 V and ECC enabled for the installed DIMM.
