Server memory upgrade

This OWC kit provides 64GB of DDR5 ECC registered RDIMM memory across four 16GB modules. It is built for Dell PowerEdge R760xa, R860 and R960 servers that require registered error-correcting memory. Workstations and standard desktop computers cannot use this module type.

Registered DDR5 limits

The modules operate at DDR5 4800 with CL40 latency and 1.1V voltage in a 288-pin form factor. Registered DIMMs add a buffer that reduces electrical load on the memory controller, so they cannot be mixed with unbuffered or load-reduced ECC memory in the same system. The 1Rx8 organisation is fixed for this kit.

Pre-order checklist

Verify that your server model is exactly R760xa, R860 or R960 and that the current configuration uses registered ECC RDIMMs. Confirm the memory slots accept 288-pin DDR5 modules and that the system firmware supports 4800MT/s registered memory. Check the existing population rules before adding four modules.

Perguntas sobre este artigo

Should I pick the 64 GB kit or add single 16 GB modules to reach the same total?

The kit supplies four matched 16 GB modules for 64 GB total, ensuring identical timing and rank across all slots.

What does the 4800 MT/s rating deliver inside a PowerEdge R760xa, R860 or R960?

The server memory controller runs the modules at DDR5 4800 with CL40 latency, providing the rated bandwidth for registered ECC workloads.

How does the 288-pin RDIMM interface limit speed or capacity in these servers?

The 288-pin registered DIMM slot accepts this 1Rx8 module at 1.1 V; the platform's memory controller governs the maximum supported speed and total capacity.
