256GB DDR5 4800 ECC RDIMM kit

This OWC kit provides 256GB of DDR5 4800 memory in four 64GB registered DIMMs. Each module operates at 1.1V with CL40 latency and 2Rx4 organisation. The kit is validated for the Dell PowerEdge XE9680 server platform.

Replaces lower-capacity or slower DDR5 RDIMMs

Upgrading from smaller registered modules or slower speeds adds total memory bandwidth and capacity for virtualisation, database or compute workloads. The jump is worth it when the XE9680 chassis has free 288-pin slots and the workload benefits from the full 256GB configuration.

Suits XE9680 operators needing maximum registered

This kit fits administrators expanding a Dell PowerEdge XE9680 with JEDEC-standard registered ECC memory. It is not for desktops, workstations requiring unbuffered DIMMs, or systems that only accept load-reduced modules.

Questions about this item

Will the 288-pin DDR5 RDIMMs fit the Dell PowerEdge XE9680 memory slots?

Yes, the kit uses the standard 288-pin DDR5 registered DIMM form factor specified for the XE9680, so the modules seat directly in the server's memory slots.

What is the correct installation sequence for the four 64 GB modules in the XE9680?

Populate the memory channels evenly across the CPU sockets, following the Dell slot-population guide for 2Rx4 registered DIMMs to avoid a POST error.

How can I tell if a module has failed and needs replacement?

The server's ECC logging will report correctable or uncorrectable errors tied to a specific DIMM slot; swap the flagged module to restore full redundancy.
