16GB DDR4 ECC RDIMM for Cisco UCS

This 16GB DDR4 2400 CL17 ECC Registered RDIMM is built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers. It provides a direct 288-pin memory upgrade for workstations and servers that require registered error-correcting modules. Standard desktop systems cannot use this memory.

Thermals and power in normal operation

The module runs at the standard DDR4 voltage of 1.2V without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping to keep power draw low during sustained server workloads. Passive cooling relies on system airflow.

Replaces Cisco UCSMR1X161RVA and UCSMR1X161RVG

This single 16GB 1Rx4 DIMM replaces those Cisco part numbers to extend the life of existing infrastructure or to add capacity when building a new configuration. The upgrade is worthwhile when your compatible server needs more registered ECC memory and you want a JEDEC-compliant module tested for reliability. It will not work with unbuffered or load-reduced DIMM types.

Preguntas sobre este artículo

How do I install this 288-pin DDR4 RDIMM into a Cisco UCS B260 M4 E7 v4 server, and what is the common mistake?

Power down the server, open the chassis, locate the DIMM slots for the CPU you are populating, align the notch on the 288-pin module with the slot key, and press firmly until the ejector tabs lock. The step people get wrong is mixing this ECC Registered RDIMM with unbuffered or load-reduced memory, which the system will not support.

What maintenance or replacement will this 16GB 1Rx4 module need later?

No routine maintenance is required for the module itself. Keep the server air filters clean and verify fan operation so the 1.2V DIMM stays within thermal limits. Replacement is only needed if a memory error appears in the system logs or a diagnostic test flags the specific 16GB stick.

What limit appears first when this CL17 2400MHz RDIMM runs under sustained load?

The first limit is the memory controller’s maximum supported capacity per channel and the total rank count per channel. Because this is a 1Rx4 Registered DIMM, you hit the rank or capacity ceiling before the CL17 latency or 2400MHz speed becomes a bottleneck.
