64 GB DDR4-2666 ECC LRDIMM for Cisco Servers

This 64 GB DDR4-2666 module uses Load Reduced ECC technology to deliver high-density memory for Cisco-compatible servers. It operates at 1.2 V with a CAS latency of 15 and a 4Rx4 rank structure. The 288-pin DIMM is built with major-brand chips from Samsung, SK Hynix or Micron. It targets administrators who need to maximise installed capacity on existing infrastructure.

Fits 288-pin DDR4 slots in Cisco UCS platforms

The module installs directly into standard 288-pin DDR4 DIMM sockets on supported Cisco UCS servers. Load Reduced buffering reduces electrical load on the memory controller, freeing the CPU to address larger total memory populations. ECC protection corrects single-bit errors to maintain data integrity for virtualisation and database workloads. Compatibility is guaranteed for systems requiring the UCS-ML-X64G4RS-H specification.

Runs at 1.2 V with standard DDR4 thermals

At 1.20 V the module follows standard DDR4 power envelopes for server memory. Load Reduced architecture helps manage signal integrity without increasing voltage. Normal airflow across the DIMM slots is sufficient for thermal management in typical rack configurations. The design meets OEM specifications for continuous operation in dense server deployments.

Questions about this item

What CAS latency does the 64GB DDR4-2666 LRDIMM run at under sustained load?

The module operates at CL15 CAS latency, which remains constant during sustained server workloads.

How much power does the 1.2V 4Rx4 LRDIMM draw and how hot does it get when running all day?

Each 64GB stick runs at 1.20V; the load-reduced design lowers electrical load on the memory bus, helping keep thermals manageable in dense server configurations.

Which server memory slots and chipset support are required for this 288-pin ECC LRDIMM to function?

The module needs a 288-pin DDR4 slot that supports ECC and load-reduced DIMMs; it uses major-brand DRAM chips validated for Cisco UCS-ML-X64G4RS-H compatibility.
