32GB DDR4 ECC RDIMM for Cisco UCS

This 32GB registered DIMM is built for Cisco UCS servers and workstations that require ECC memory. It replaces part numbers UCS-MR-1X322RU-A, UCS-MR-1X322RU-G and related Cisco spares. The module suits administrators upgrading validated platforms where data integrity and registered buffering are mandatory. Buyers needing non-ECC or unbuffered memory for consumer boards cannot use this module.

Capacity and speed headroom

The single 32GB rank delivers 2133 MT/s at CL15 on 1.20V, matching the PC4-17000 specification. A 2Rx4 organisation provides density for virtualisation hosts and database nodes that benefit from large per-slot capacity. Workloads demanding higher frequencies or lower latencies than DDR4-2133 will not gain from this module.

Registered DIMM build and 288-pin fit

Registered signalling reduces electrical load on the memory controller, enabling stable operation in multi-DIMM server configurations. The 288-pin DDR4 DIMM form factor seats in standard server slots keyed for registered ECC modules. Systems that accept only unbuffered UDIMMs or a different pin count will not recognise this memory.

Questions about this item

Will the 2Rx4 registered ECC DDR4 2133MHz module run with my existing CL15 1.20V DDR4 RDIMMs?

Yes, it matches the same DDR4 2133MHz PC4-17000 speed, CL15 latency, 1.20V voltage, ECC registered design and 2Rx4 rank, so it will operate alongside identical spec modules.

How can I confirm the 32GB DDR4 2133MHz ECC RDIMM is detected correctly after installation?

Check the server BIOS or UEFI memory information screen — it should show a single 32GB DDR4 2133MHz registered ECC module at 1.20V with CL15 timing and 2Rx4 organisation.

Does the box contain only the 288-pin DDR4 DIMM or are any cables or brackets included?

The package includes one 32GB DDR4 2133MHz ECC RDIMM 2Rx4 module; no cables, brackets or additional accessories are supplied.
