Cisco UCS-MR-1X161RV-A DDR4 Server Memory

This Cisco UCS-MR-1X161RV-A module provides 16GB of DDR4 server memory. It operates at 2400MHz with a PC4-19200 rating and CL17 latency. The single-rank registered DIMM runs at 1.2V and uses a 288-pin form factor. It is built for compatible Cisco UCS platforms requiring ECC reliability.

Registered ECC with single-rank layout

The registered buffer reduces electrical load on the memory controller, allowing larger total capacities per channel. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. Single-rank organisation can improve command timing on platforms optimised for that topology. The 1.2V operating voltage matches standard DDR4 power envelopes.

Suited for Cisco UCS upgrades needing registered ECC

This module fits administrators expanding memory in qualified Cisco UCS servers that require registered ECC DDR4 at 2400MHz. It is not for desktop PCs or laptops that accept only unbuffered non-ECC SODIMMs. Builders needing higher frequencies, lower latencies or different capacities should verify their platform specifications first.

Questions about this item

Will the 16GB DDR4-2400MHz ECC registered DIMM need replacement after a certain period?

The module is solid-state with no moving parts or batteries, so it does not have a scheduled replacement interval; it runs at 1.2V with CL17 latency and should last the server's service life unless a fault develops.

What limit appears first when the 288-pin single-rank stick runs at 2400MHz continuously?

The registered buffer and 1.2V operation keep signal integrity stable, so the practical ceiling is the 16GB capacity per DIMM rather than thermal or electrical throttling under sustained load.

How much heat and power does the 16GB PC4-19200 module produce during all-day operation?

At 1.2V the stick draws low power and runs cool; the registered design adds negligible overhead, so noise remains limited to the server's own cooling fans.
