Overview

At 128GB per module, this is a high-density part for hosts where memory capacity is the constraint. The Lenovo ThinkSystem 128GB 2S2Rx4 DDR4-3200 3DS RDIMM TruDDR4 Memory, part number 4X77A08636, is listed for the ThinkSystem SR650 V2.

The module type is 3DS RDIMM, a registered design that stacks dies to reach this capacity, and the rank code 2S2Rx4 reflects that stacking. It runs DDR4 at 3200 MT/s on 1.2 V and supports ECC. Because stacked modules are a different type from standard RDIMMs, check the memory population rules for your host before mixing them with other modules.

Two conditions are listed: new and refurbished. Each has a warranty of 1 year or 3 years. There is no used offer. A note on your target memory configuration will let us confirm stock before we price it.
