Dell PowerEdge DDR5 ECC Kit

This 32GB kit contains two 16GB DDR5 4800 CL40 registered ECC RDIMMs built for Dell PowerEdge C6600, C6620, MX760C, R660 and R6615 servers. The modules run at 1.1V with a 1Rx8 organisation and fit 288-pin DDR5 slots. They are JEDEC-standard and RoHS compliant.

For servers needing registered ECC

Suits administrators upgrading or repairing the listed PowerEdge platforms where registered ECC memory is required. Not for standard desktop PCs, workstations that take unbuffered ECC, or systems needing load-reduced DIMMs. Buyers who need higher capacities per module or mixed-rank populations should verify their platform limits before ordering.

Kit simplifies matched installation

The two-module pack delivers a matched pair so the memory controller can run in dual-channel mode without manual bin sorting. No heat spreaders are included, relying on server chassis airflow. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme.

Questions about this item

Which Dell PowerEdge servers must I already own for this 288-pin DDR5 4800 CL40 ECC Registered RDIMM kit to work?

The kit is validated for Dell PowerEdge C6600, C6620, MX760C, R660 and R6615 servers.

Can I keep my existing unbuffered or load-reduced ECC modules and add this registered RDIMM kit alongside them?

No. The manufacturer states this registered memory cannot be mixed with unbuffered or load-reduced ECC modules.

How do I confirm the 32 GB kit is running at 4800 MT/s with CL40 latency after installation?

Check the BIOS or system management console; it should report DDR5 4800 (PC5-38400) speed and CL40 timings for each 16 GB module.
