32 GB DDR4 ECC RDIMM for Cisco UCS

This 32 GB DDR4 2400 CL17 registered DIMM is built for Cisco UCS B200 M4 and C220 M4 servers. It delivers ECC protection and registered buffering for workloads that demand data integrity and sustained uptime in enterprise environments.

Tool-free DIMM installation with registration rules

The 288-pin module seats in a standard DDR4 slot without tools, but the registered ECC design means it cannot be mixed with unbuffered or load-reduced memory. Populating slots in the order specified by the Cisco service guide avoids the most common boot-time errors.

Verify Cisco part numbers and slot population

Confirm the server uses part numbers such as HXMR1X322RVA or UCSMR1X322RVA before ordering. Check the existing memory configuration for rank limits per channel and ensure all installed modules share the same registered ECC specification.
