Overview

A 256GB DDR5 module is for hosts where memory capacity is the headline requirement. The Lenovo ThinkSystem 256GB 8Rx4 DDR5-5600 3DS RDIMM TruDDR5 Memory, part number 4X77A88055, is a 3DS RDIMM with an 8Rx4 layout, listed for the ThinkSystem SR650 V3.

It operates at 5600 MT/s and includes ECC. Stacked-die construction is how modules reach this density, and the eight-rank code is part of that. A few of these in a server can carry very large datasets in memory, which suits analytics platforms and heavily consolidated virtualization.

This MPN is available new, refurbished or used. New and refurbished units have a warranty of 1 year or 3 years. Used units have 90 days. Tell us the host model and the exact count, and we will check availability for your country.
