Server-grade DDR4 ECC RDIMM

This OWC module delivers 16GB of DDR4 2400 registered ECC memory for Cisco UCS B200 M4 and C220 M4 servers. The 288-pin RDIMM operates at 1.2V with CL17 latency and a 1Rx4 organisation. It is built for workstation and server platforms that require registered error-correcting memory.

Capacity and registered bandwidth headroom

The single 16GB rank plugs directly into a compatible DDR4 slot to expand system memory without mixing with unbuffered or load-reduced modules. Registered buffering and ECC maintain data integrity under sustained multi-threaded workloads typical of virtualisation and database tasks. The PC4-19200 rating sets the maximum throughput ceiling for this module.

Replaces Cisco UCSMR1X161RVA and UCSMR1X161RVG

This part number serves as a direct replacement for the listed Cisco service parts when upgrading or servicing B200 M4 and C220 M4 chassis. The jump is worthwhile when existing DIMMs limit total capacity or when a failed module must be matched with identical registered ECC specifications. It will not work in standard desktop computers or systems requiring unbuffered memory.

Questions about this item

Will this 16GB DDR4 2400 CL17 ECC RDIMM work alongside other DDR4 ECC Registered modules in my Cisco UCS B200 M4?

Yes, it can operate with other DDR4 ECC Registered DIMMs, but the manufacturer highlights state it cannot be mixed with unbuffered or ECC load reduced memory types.

How can I verify the 1Rx4 module is running at the correct 2400 MHz speed and 1.2V voltage after installation?

Check the server BIOS or system management interface; it should report the DIMM as 16GB DDR4 2400 (PC4-19200) CL17 at 1.2V with ECC Registered status active.

Does the box contain only the 288-pin 16GB RDIMM, or are any cables, brackets or cooling accessories included?

The upgrade consists of a single 16GB DDR4 2400 PC4-19200 CL17 1Rx4 288-pin 1.2V ECC Registered DIMM module; no extra cables, brackets or heat spreaders are supplied.
