Targeted Server Upgrade

This OWC 16GB DDR5 4800 CL40 ECC Registered RDIMM is built for Cisco UCS C220 M7 SFF, C240 M7 SFF, X210c M7 and X410c M7 systems. It replaces Cisco part number UCS-MRX16G1RE1 with a single 1Rx8 288-pin module running at 1.1V. The registered design adds stability for multi-module server configurations.

Replaces Factory Memory

The module upgrades the original DDR5 4800 PC5-38400 memory fitted to the listed Cisco UCS M7 platforms. The jump is worth it when expanding total capacity or replacing a failed stick without mixing registered and unbuffered or load-reduced types. JEDEC and RoHS compliance keeps the upgrade warranty-safe.

Suits Cisco UCS M7 Owners

This memory suits administrators extending the life of Cisco UCS C220, C240, X210c or X410c M7 servers. It is not for desktop PCs, workstations that require unbuffered ECC, or systems needing load-reduced DIMMs. Buyers with incompatible platforms should verify their motherboard manual before ordering.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the memory slots in a Cisco UCS C220 M7 SFF server?

Yes, the module is a 288-pin DDR5 ECC Registered DIMM built for the Cisco UCS C220 M7 SFF, C240 M7 SFF, X210c M7 and X410c M7 platforms.

What is the correct way to seat the 1Rx8 registered module so the server recognises the full 16GB capacity?

Align the notch on the 288-pin edge connector with the key in the slot, press firmly until both retention clips click, and populate slots per the Cisco memory population guide for 1Rx8 RDIMMs.

When should the 1.1V ECC registered DIMM be replaced to keep the Cisco UCS server running reliably?

Replace the module if the server logs correctable ECC errors that rise over time, if memory diagnostics report failures, or during a planned hardware refresh cycle.
