32 GB DDR4 ECC Registered kit for Cisco UCS

This kit provides two 16 GB DDR4 2400 modules in a 288-pin RDIMM form factor. It is built for Cisco UCS B200 M4 and C220 M4 servers and workstations. Standard desktop systems cannot use registered ECC memory, so this upgrade is not for consumer PCs or unbuffered platforms.

Capacity and headroom

The 32 GB total (2 x 16 GB) runs at PC4-19200 with CL17 latency and 1.2 V. Registered ECC operation adds data integrity for virtualisation, databases and multi-user workloads. Capacity stops at the installed DIMM count; larger datasets or heavier consolidation will require additional slots or higher-density modules.

What the bundle changes

The matched pair enables dual-channel population on supported Cisco boards without mixing ranks or voltages. It replaces Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG directly. No heat spreaders are included, so airflow must follow the server chassis design.

Questions about this item

Will these DDR4 2400 CL17 ECC Registered RDIMMs work alongside the existing DDR4 ECC Registered modules in my Cisco UCS B200 M4?

Yes, the kit is validated for Cisco UCS B200 M4 and C220 M4 servers and uses the same DDR4 ECC Registered RDIMM form factor as factory memory.

How can I verify the 32 GB kit is running at DDR4 2400 CL17 with ECC active after installation?

Check the system BIOS or Cisco UCS Manager; it will report 32 GB total, 2400 MT/s speed, CL17 latency and ECC Registered status for each DIMM.

What does the box contain and is anything else required for installation?

The upgrade kit includes two 16 GB DDR4 2400 PC4-19200 CL17 1Rx4 288-pin 1.2 V ECC Registered RDIMM modules; no additional parts are needed.
