System-specific DDR5 ECC RDIMM kit

This OWC upgrade kit provides 512GB of DDR5 4800 registered ECC memory across four 128GB modules. It is built for the Dell PowerEdge XE9680 server platform and operates at 1.1V with CL40 latency. The 288-pin RDIMM format and 4Rx4 organisation are tailored for enterprise workloads.

Verify registered ECC requirement and slot count

Confirm that your XE9680 requires registered ECC RDIMMs and cannot accept unbuffered or load-reduced modules. Ensure the system has at least four available DDR5 slots to accommodate the full kit. Mixing registered memory with other ECC types will prevent operation.

Suits XE9680 expansion.

This kit suits administrators expanding a Dell PowerEdge XE9680 with validated registered ECC capacity. It is not for standard desktop PCs, workstations needing unbuffered memory, or servers that require load-reduced DIMMs. Buyers needing different capacities or speeds should look elsewhere.

Questions about this item

What comes in the 512GB kit and do I need anything else to install it?

The kit contains four 128GB DDR5 4800 CL40 4Rx4 ECC Registered 288-pin RDIMM modules. No extra parts are required for installation in a compatible Dell PowerEdge XE9680.

Should I choose this 512GB 4x128GB kit or a different capacity for my XE9680?

This 512GB kit uses four 128GB 4Rx4 registered DIMMs at 4800 MT/s CL40. Select it when your XE9680 configuration calls for 4Rx4 registered modules at this speed and density.

What does the 4800 CL40 rating deliver in a running XE9680?

The modules operate at 4800 MT/s with CAS latency 40 at 1.1V, providing JEDEC-standard DDR5 bandwidth and error correction for the XE9680 memory subsystem.
