1TB DDR5 ECC RDIMM Kit

This kit provides one terabyte of DDR5 memory in sixteen 64 GB registered DIMMs. It is built for the Cisco UCS C220 M7 rack server and uses ECC RDIMM modules that operate at 4800 MT/s with a CL40 latency. The registered design helps maintain signal integrity across all populated slots.

Suits Cisco UCS C220 M7 upgrades

Administrators expanding a Cisco UCS C220 M7 to its maximum supported capacity will use this exact 16-module configuration. Buyers who need a smaller capacity increase, a different speed grade, or memory for another server platform should select a kit that matches those specific requirements.

16-module population fills all slots

The kit contains sixteen individual 64 GB RDIMMs, which occupies every DIMM slot in a fully populated Cisco UCS C220 M7. Verifying that the server’s memory controller supports this total rank count and population rule is the single step that confirms compatibility.

Questions about this item

Should I buy the 16-module 1 TB kit or a smaller capacity?

The kit contains 16 modules of 64 GB each for a total of 1 TB. Choose it when your Cisco UCS C220 M7 has enough 288-pin DDR5 slots and your workload needs that full capacity.

What does the 4800 speed rating deliver in the Cisco UCS C220 M7?

DDR5 4800 (PC5-38400) runs at 4800 MT/s with CL40 latency and 1.10 V, giving the maximum standard throughput the server's memory controller supports for registered ECC modules.

How does the 288-pin RDIMM interface limit this upgrade?

The 288-pin DDR5 RDIMM form factor fits only DDR5 registered DIMM slots. The registered buffer and ECC function require a server chipset that supports both; consumer boards cannot use these modules.
