Capacity and role

This is a single 64GB DDR4 2933 ECC Load Reduced DIMM built for server and workstation platforms that require registered memory. It replaces Cisco part numbers UCS-ML-X64G4RT-H and 15-106198-01 in compatible systems.

Thermals noise and power

The module operates at the standard 1.2V DDR4 voltage with CL21 latency, keeping power draw predictable in dense multi-socket configurations. Load Reduced architecture reduces electrical load on the memory controller, helping maintain stable thermals under sustained workloads.

Build and connectors

A 288-pin DIMM form factor with 4Rx4 organisation fits slots wired for LRDIMM support; the 262-pin notation in some datasheets refers to the same mechanical interface. ECC circuitry corrects single-bit errors to protect data integrity in mission-critical applications.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM and which step causes the most errors?

Align the notch on the module with the key in the 288-pin slot, press straight down until both side latches click, and verify the system detects 64GB at 2933 MHz; the most common error is stopping before the latches fully engage.

What maintenance or replacement will this ECC LRDIMM need over its service life?

No routine maintenance is required; keep air intakes clear so the 1.2 V module stays cool, and replace it only if memory diagnostics report uncorrectable ECC errors or the system fails to boot.

What limit appears first when this 4Rx4 module runs sustained workloads?

The four-rank density per channel usually hits the platform's maximum rank count before bandwidth or thermal limits become an issue.
