Server Memory Upgrade

This 128GB DDR5 ECC registered RDIMM is built for Cisco UCS M7 servers including the C220 M7 SFF, C240 M7 SFF, X210c M7 and X410c M7. It targets administrators who need to expand memory capacity in these specific platforms. The module will not work in standard desktop computers or consumer motherboards. It also cannot be mixed with unbuffered or load-reduced memory types.

DDR5 4800 Interface Limits

The module runs at DDR5 4800 with a CAS latency of CL40 and operates at 1.1V. These JEDEC-standard timings define the practical speed ceiling for this memory generation. Systems that only support lower DDR5 data rates will downclock the module automatically. Buyers who need higher frequencies or tighter latencies must select a different specification.

128GB Single-Module Capacity

Each DIMM provides 128GB in a 4Rx4 organisation using 288-pin form factor. This density allows large memory footprints with fewer occupied slots. Buyers who require more total capacity than the server's slot count permits with this module size should verify maximum supported memory per socket before purchasing.

Questions about this item

Should I choose the 128GB module or add multiple smaller DIMMs to reach the same capacity?

This single 128GB DDR5 4800 CL40 4Rx4 ECC RDIMM fills one 288-pin slot, leaving remaining slots free for future expansion in your Cisco UCS M7 server.

What does the 4800MHz speed actually deliver when the module is installed in a Cisco UCS C220 M7 or C240 M7?

The module runs at the JEDEC-standard DDR5 4800 data rate with CL40 latency, providing the rated PC5-38400 bandwidth the platform expects for registered ECC memory.

How does the DDR5 4800 PC5-38400 interface limit performance in these Cisco UCS M7 systems?

The 288-pin registered ECC DDR5 4800 interface caps throughput at the PC5-38400 rate; the server memory controller will not exceed this speed with this module.
