Overview

Lenovo 4X77A90964 is a 32 GB TruDDR5 RDIMM in a 1Rx4 layout, rated at 6400 MT/s. It is the registered format used in mainstream ThinkSystem servers.

Send us your server model and we will confirm the fit and ECC support before you place an order. The speed grade requires a platform that supports 6400 MT/s, or the module will be limited by the server.

Single-rank modules at this size use x4 chips, which is how a 32 GB module gets by with just one rank.

Registered memory like this is intended for servers with many slots, so make sure your system is built for RDIMMs before ordering.

Choose from new and refurbished, each with a 1 year or 3 years warranty.
