Cisco UCS X210c M7 memory kit

This 512GB kit contains four 128GB DDR5 RDIMMs built for the Cisco UCS X210c M7 compute node. It targets IT teams who need maximum registered ECC capacity in a single qualified configuration.

DDR5 4800 registered ECC limits

The modules run at DDR5 4800 (PC5 38400) with CL40 latency at 1.10V. Registered buffering and 4Rx4 organisation add command overhead that caps raw throughput compared with unbuffered memory, while ECC correction cycles consume a portion of bandwidth.

Replaces smaller or slower DDR5 kits

Upgrading from lower-capacity or lower-speed DDR5 RDIMMs is worthwhile when workloads exceed current memory headroom or when memory bandwidth becomes the bottleneck. The jump adds cost and power draw without benefit if the node already has sufficient capacity for its active dataset.

Questions about this item

Should I buy the 512GB kit or look for a smaller capacity?

The kit ships as four 128GB modules totalling 512GB; choose it when the Cisco UCS X210c M7 requires maximum memory density per slot.

What does the 4800MHz rating mean once the memory is installed in the Cisco UCS X210c M7?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, delivering the rated throughput the compute node's memory controller supports.

Is the 288-pin RDIMM interface compatible with the Cisco UCS X210c M7 and what limits apply?

Yes, the 288-pin ECC registered DDR5 RDIMMs match the compute node's slots; the 4Rx4 organisation and 1.10V operation define the electrical and timing envelope.
