Cisco UCS C200 M2 and C210 M2 upgrade kit

This 64GB kit contains four 16GB DDR3L 1600 registered ECC RDIMMs built for Cisco UCS C200 M2 and C210 M2 servers. Each module runs at PC3L-12800 CL11 with a 1.35V operating voltage and a 2Rx4 rank configuration. The 240-pin form factor matches the memory slots in those specific platforms.

Workstation and server builders who need

Buyers who want unbuffered or load-reduced DIMMs cannot use this kit because registered modules will not operate in those configurations. Standard desktop computers and consumer laptops also reject registered ECC memory, so this product is unsuitable for those systems.

Four matched modules simplify population

The kit supplies four identical 16GB sticks, allowing all channels to be filled with a single purchase and eliminating the risk of mixing ranks or speeds. No additional software, cables or heat spreaders are included in the package.

Questions about this item

Does this 64 GB kit require a Cisco UCS C200 M2 or C210 M2 server to work?

Yes, the kit is validated for Cisco UCS C200 M2 and C210 M2 servers; it uses 240-pin DDR3L ECC Registered DIMMs at 1.35 V and will not work in standard desktop boards.

Can I mix these 16 GB 2Rx4 modules with existing unbuffered or load-reduced DIMMs in the same server?

No, the manufacturer states these ECC Registered modules cannot be mixed with unbuffered or ECC load-reduced memory; populate all channels with matching registered DIMMs.

How do I confirm the server recognises all 64 GB at 1600 MHz CL11 after installation?

Check the BIOS memory information or OS memory report — it should show 64 GB total, DDR3L 1600 (PC3L-12800) speed, CL11 latency and ECC registered status.
