Cisco UCS Compatible 64GB LRDIMM

This 64GB DDR4 2933 module uses a Load Reduced ECC design built for Cisco UCS servers. The 4Rx4 organisation and 1.2V operation target high-density memory channels in enterprise platforms. It is sold new as a single 288-pin stick.

Verify Slot Count and Rank Limits

Check the system documentation for maximum supported capacity per channel and total rank allowance. Confirm the motherboard accepts 4Rx4 Load Reduced modules at 2933 MT/s and that BIOS revision allows the stated CAS latency of 21. Ensure the server chassis has a free 288-pin DDR4 slot before ordering.

Fits Cisco UCS Memory Channels

The module plugs directly into a standard 288-pin DDR4 slot and draws 1.2V from the platform. Its Load Reduced buffer reduces electrical load on the memory controller, freeing rank budget for additional modules. No heat spreader is fitted, so airflow across the PCB must be provided by the server cooling design.

Questions about this item

Does the module ship alone or as part of a kit, and are any brackets or cables required for installation?

The package contains a single 64 GB 288-pin DDR4 LRDIMM; no brackets, cables or additional parts are included or required for installation in a compatible Cisco server.

Why does the same 64 GB capacity list both 1Rx64 and 4Rx4, and which one should I select?

The module supplied is 4Rx4; the 1Rx64 reference in the product name is a typographical inconsistency. Choose the 4Rx4 rank configuration to match the Cisco UCS-ML-X64G4RT-H1 specification.

What does the PC4-23400 rating tell me about real-world performance in a Cisco server?

PC4-23400 is the JEDEC standard designation for DDR4-2933 memory; the module runs at 2933 MT/s with CL21 latency and 1.20 V, delivering the rated speed when installed in a supported Cisco platform.
