System-Specific DDR4 ECC Kit

This 32 GB kit contains two 16 GB registered DIMMs built for the Cisco UCS C4200 server. Each module runs at DDR4 3200 with CL22 latency and 1.2 V operation. The ECC registered design targets workstation and server workloads that require error correction.

Registered 288-Pin Form Factor

The 288-pin RDIMM layout fits only platforms that accept registered ECC memory. It cannot be mixed with unbuffered or load-reduced DIMMs. The kit replaces Cisco part numbers UCSMRX16G1RW and UCSXMRX16G1RW for direct compatibility.

Dual-Rank 1Rx4 Organisation

Two single-rank 1Rx4 modules provide 32 GB total capacity for virtualisation or database tasks. Registered buffering adds electrical load that limits maximum DIMM count per channel. Systems needing larger memory footprints must verify slot population rules.

Questions about this item

Will the CL22 latency become a bottleneck during sustained heavy workloads?

CL22 is the rated CAS latency for these DDR4 3200 modules; under sustained load the latency remains at this specification and does not increase.

How much heat do these 1.2V registered DIMMs generate when running continuously?

Operating at 1.2V without a heat spreader, the modules produce low heat typical for registered DDR4 server memory.

Does my Cisco UCS C4200 need any specific firmware or BIOS version to recognise this 2Rx4 kit?

The kit is validated for the Cisco UCS C4200 and replaces Cisco part numbers UCSMRX16G1RW and UCSXMRX16G1RW.
