System-specific DDR4 kit for Cisco UCS C4200

This 128GB upgrade kit contains two 64GB DDR4 3200 ECC registered DIMMs built for the Cisco UCS C4200 server. It is intended for administrators who need to expand memory capacity in that platform. The modules will not work in standard desktop computers or consumer motherboards.

Registered ECC DDR4 limits mixing and platform fit

Registered ECC DDR4 modules cannot be mixed with unbuffered or load-reduced memory in the same system. The 288-pin DDR4 form factor fits only DDR4 server or workstation slots that support registered operation and the required CAS latency of CL22 at 1.2V.

2Rx4 64GB density per module decides slot planning

Each DIMM is a 64GB 2Rx4 device, so the kit occupies two memory slots with the maximum density per module this platform accepts. Buyers who need a different rank configuration or smaller per-module capacity must choose another kit.

Questions about this item

Should I buy the 2x64GB kit or look for a single 128GB module?

This upgrade kit is sold as a matched pair of two 64GB modules, giving 128GB total capacity for the Cisco UCS C4200.

What does the DDR4 3200 CL22 rating actually deliver in the Cisco UCS C4200?

The modules run at 3200 MT/s with CAS latency 22, providing registered ECC bandwidth of PC4-25600 inside the qualified server platform.

Is the 288-pin DDR4 RDIMM interface limited by the Cisco UCS C4200 memory controller?

The 288-pin registered DIMM uses the DDR4 interface at 1.2V; maximum speed and capacity are determined by the C4200 memory controller and qualified configuration.
