Overview

Sixty-four gigabytes on a dual-rank x4 module: the Lenovo ThinkSystem 4X77B07420 is an RDIMM-A marked v2, rated at DDR5 6400MT/s with ECC.

The four named systems are the ThinkSystem SR675 V3, SR675i V3, SD665 V3 Neptune DWC and SD665-N V3 Neptune DWC, and the feature code is CA1L. Large modules like this matter on dense nodes, where each socket needs ample memory but the board has a fixed number of slots.

When planning, confirm which v2 module your platform expects. Lenovo issues multiple revisions of similar capacities, and the listed platforms are the guide to which one belongs with your server.

We supply the part in all three conditions. New and refurbished units carry 1 year or 3 years of warranty, and used units carry 90 days. Send your quantity and server model and we will reply with pricing.
