8 GB Registered DDR4 Module

This single 8 GB DDR4 module operates at 2400 MT/s with a CL17 latency and 1.20 V supply. It uses a 288-pin RDIMM form factor and a 1Rx8 organisation. The module is built for server platforms that require registered memory.

Suited for registered-DDR4 servers

The stick fits servers that accept registered DDR4 RDIMMs at 2400 MT/s. It is not for systems that need error-correcting code memory, nor for desktop or laptop boards that only support unbuffered DIMMs. Buyers who need ECC protection or higher capacities should look at other modules.

Registered RDIMM form factor

The registered buffer is the specification that decides compatibility. Only motherboards designed for registered DDR4 RDIMMs can use this module; unbuffered consumer boards cannot.
