Server-grade DDR4 ECC RDIMM

This 16 GB DDR4 2400 CL17 registered DIMM is built for Cisco UCS B420 M4 and C460 M4 servers. It delivers error-correcting, buffered memory for workloads that demand data integrity and sustained uptime.

Verify registered ECC support

Confirm your system requires 288-pin registered ECC RDIMMs at 1.2 V and does not use unbuffered or load-reduced modules. Mixing registered memory with other ECC types will prevent boot or cause instability.

Replaces Cisco UCSMR1X161RVA and UCSMR1X161RVG

The module matches the original 1Rx4 organisation and PC4-19200 speed. The upgrade is worthwhile when expanding capacity on supported platforms or when a failed DIMM must be swapped with a validated equivalent.

Questions about this item

Does the module ship alone or with any extra parts, and what must I source separately?

The package contains a single 16GB DDR4 2400 CL17 288-pin ECC Registered RDIMM. No cables, brackets or tools are included; you only need a compatible Cisco UCS B420 M4 or C460 M4 (DDR4) slot.

I see one 16GB 2400 CL17 ECC Registered RDIMM listed — are there other capacities or speeds for this same platform?

This listing covers the 16GB 2400 CL17 1Rx4 1.2V Registered module that replaces Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG. Other capacities or speeds would be separate part numbers.

What does the 2400 CL17 rating actually deliver inside a Cisco UCS B420 M4 or C460 M4?

In those servers the module runs at DDR4 2400 (PC4-19200) with CAS latency 17 at 1.2V, providing ECC error correction and registered buffering for stable operation in multi-DIMM configurations.
