Server ECC RDIMM kit

This OWC kit supplies 64GB of DDR5 memory as two 32GB registered DIMMs. Each module runs at 4800 MT/s with CL40 latency at 1.1V. The parts are built for Cisco UCS C220 M7 SFF, C240 M7 SFF, X210c M7 and X410c M7 servers. They use a 288-pin form factor with ECC and registered buffering.

Not for desktop or unbuffered builds

This memory will not work in standard desktop PCs or consumer motherboards. It cannot be mixed with unbuffered or load-reduced DIMMs. Buyers who need non-ECC modules, different voltages or laptop SO-DIMMs should look elsewhere.

Registered ECC at 4800 MT/s

The registered ECC design with a single 1Rx4 rank per module is the specification that determines compatibility. Only systems qualified for DDR5 4800 registered ECC RDIMMs can use this kit.

Perguntas sobre este artigo

What slot type and pin count does this 288-pin DDR5 RDIMM require?

It installs in a standard DDR5 288-pin RDIMM slot on the Cisco UCS C220 M7 SFF, C240 M7 SFF, X210c M7 or X410c M7 motherboard.

What is the correct sequence for seating both 32 GB modules so the registered buffer initialises?

Power down the server, open the chassis, align each module's key notch with the slot, press firmly until both retention clips click, then power on.

When should the 1.1 V ECC registered DIMMs be reseated or replaced?

Reseat only if the system reports correctable ECC errors after a firmware update; replace if uncorrectable errors persist or a module fails POST.
