16GB DDR4 2400 Registered DIMM

This 16GB DDR4 module runs at 2400 MT/s with CL17 latency and 1.20V operation. It uses a 288-pin registered design with 2Rx4 organisation and includes ECC error checking. The part is built for Lenovo systems that require registered memory.

Workstations and servers needing registered ECC

Suits Lenovo platforms that specifically call for DDR4 2400 registered DIMMs with CL17 timing. Not for consumer desktops or laptops that accept only unbuffered non-ECC modules. Buyers who need unbuffered memory or a different speed grade should look elsewhere.

Registered 2Rx4 ECC at DDR4 2400

The registered 2Rx4 ECC configuration is the single specification that determines compatibility. Only systems qualified for this exact registered DDR4 2400 CL17 layout will support the module.
