Cisco UCS C4200 memory kit

This 64GB kit contains two 32GB DDR4 3200 ECC registered RDIMMs built for the Cisco UCS C4200 server. Each module runs at CL22 latency and 1.2V using a 2Rx4 organisation. The upgrade targets administrators who need to expand capacity on this specific platform.

Registered ECC build and 288-pin fit

Registered buffering and on-die ECC protect data integrity in multi-socket workloads. The 288-pin DDR4 form factor seats directly in the C4200 memory slots without adapters. No heat spreaders are fitted, so airflow clearance follows the chassis design. Mixing with unbuffered or load-reduced DIMMs is not supported.

Replaces Cisco 15-107238-01 and UCSMRX32G2RW

The kit substitutes Cisco part numbers 15-107238-01, UCSMRX32G2RW and UCSXMRX32G2RW. The jump is worthwhile when current memory limits virtual-machine density or database buffer size on the C4200. Buyers who need more than 64GB per channel or a different DDR generation cannot use this kit.

Questions about this item

What DDR4 speed does the PC4-25600 rating on this kit actually run at?

The PC4-25600 rating corresponds to DDR4 3200, so the modules operate at 3200 MT/s when installed in the Cisco UCS C4200.

Will these 288-pin ECC Registered DIMMs fit the memory slots in a Cisco UCS C4200?

Yes, the 288-pin RDIMM form factor matches the Cisco UCS C4200 memory slots; the kit is built specifically for that server.

What is the correct way to install the two 32 GB modules in the Cisco UCS C4200?

Insert both DIMMs into the same channel pair as specified in the Cisco UCS C4200 service guide; a common mistake is populating mismatched channels.
