16GB DDR4 2666MHz ECC Registered RDIMM

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It is a 288-pin registered DIMM with ECC and a 2Rx8 rank configuration. The memory is designed for server and workstation platforms that require registered ECC technology.

For Dell PowerEdge R6415 R7415 R7425 XR2 servers

This upgrade fits Dell PowerEdge R6415, R7415, R7425 and XR2 systems. It replaces Dell part numbers including A9781928, AA138422 and SNPDFK3YC/16G. Buyers needing unbuffered memory for standard desktops or laptops cannot use this registered ECC module.

Registered ECC DDR4 at 2666MHz CL19

The registered ECC design with CL19 timing at 2666MHz is the decisive specification. Systems must support DDR4 registered ECC RDIMMs; mixing with unbuffered memory is not supported. Backward compatibility extends to 2133MHz and 2400MHz bus speeds.

Questions sur cet article

Does the PowerEdge R7415 need a specific CPU or motherboard revision to accept this 2666MHz ECC registered RDIMM?

The module is listed as compatible with the PowerEdge R7415, R6415, R7425 and XR2. It requires a system that supports DDR4 ECC registered memory.

Can I mix these 2666MHz CL19 registered modules with the 2400MHz ECC RDIMMs already installed in my R6415?

The product notes backward compatibility with 2133MHz and 2400MHz speeds, but registered ECC memory cannot be mixed with unbuffered modules.

After installing the 16GB 2Rx8 RDIMM, what should I check in the BIOS to confirm it is running at 2666MHz with ECC active?

Verify the memory speed shows 2666MHz (PC4-21300), the CAS latency reads CL19, voltage is 1.2V and ECC status is reported as enabled.
