OWC 64GB DDR4 ECC RDIMM Kit for Cisco UCS C4200

This OWC kit provides 64GB of DDR4 3200 registered ECC memory across four 16GB modules. It is built for the Cisco UCS C4200 server platform and uses 288-pin RDIMMs with a CAS latency of 22 and 1.2V operation. The modules are 1Rx4 ranked and validated for JEDEC compliance.

Suited for Cisco UCS C4200 upgrades only

This memory fits the Cisco UCS C4200 and replaces Cisco part numbers UCSMRX16G1RW and UCSXMRX16G1RW. It will not work in standard desktop computers or systems that require unbuffered or load-reduced DIMMs. Builders needing non-ECC memory or a different form factor must choose another product.

64GB registered ECC capacity for server workloads

The four-module kit delivers 64GB total capacity for virtualization, database or compute tasks on the supported platform. Registered ECC operation helps maintain data integrity under sustained load. Systems requiring more than 64GB or a different memory speed will need alternative modules.

Questions about this item

Does this kit require a Cisco UCS C4200 server with ECC registered RDIMM slots?

Yes, it is built for the Cisco UCS C4200 and uses 288-pin DDR4 ECC registered RDIMMs that only fit servers supporting registered ECC memory.

Can I mix these 16 GB 1Rx4 modules with existing unbuffered or load-reduced DIMMs in the same server?

No, registered ECC modules cannot be mixed with unbuffered or load-reduced memory; all slots must use matching registered ECC DIMMs.

How can I verify the kit runs at 3200 MT/s with CL22 after installation?

Check the server BIOS or operating-system memory report; it should show 3200 MT/s speed and CAS latency 22 for each of the four 16 GB modules.
