Server ECC RDIMM kit

This OWC kit supplies 128GB of DDR5 memory through eight 16GB registered DIMMs. Each module runs at 4800 MT/s with CL40 latency at 1.1V and includes ECC error correction. The 288-pin RDIMM form factor is built for Dell PowerEdge R760xa, R860 and R960 servers.

Workstation and server upgrades only

The modules suit administrators expanding memory in the listed PowerEdge platforms or building new server configurations that require registered ECC DDR5. They will not work in standard desktop boards, consumer workstations or any system that expects unbuffered or load-reduced DIMMs.

Registered ECC DDR5 at 4800 MT/s

The single specification that decides fit is the registered ECC DDR5 4800 MT/s 288-pin RDIMM interface. Only systems qualified for this exact module type can accept the kit.

Questions about this item

Does my server need DDR5 slots and support for ECC Registered RDIMMs to use this 128GB kit?

Yes, the modules are 288-pin DDR5 4800 CL40 ECC Registered RDIMMs at 1.1V, so the motherboard must accept DDR5 ECC Registered memory.

Can I mix these 1Rx8 ECC Registered DIMMs with Load-Reduced or Unbuffered ECC memory already in the PowerEdge?

No, the manufacturer highlights state this ECC Registered memory cannot be mixed with ECC Load Reduced or Unbuffered ECC modules.

After installation, how can I confirm the 8x16GB kit is running at the rated 4800 MT/s with CL40 timings?

Check the BIOS or system management firmware; it should report DDR5 4800 (PC5-38400) speed and CL40 CAS latency for all 128GB.
