Lenovo 7X77A01302 16GB DDR4 2666 RDIMM Memory Module

The Lenovo 7X77A01302 is a 16 GB DDR4 RDIMM that expands the memory capacity of Lenovo ThinkSystem servers while maintaining the stability administrators expect in an enterprise rack. Running at 2666 MHz, it pairs a 1Rx4 layout with ECC error correction to keep data accurate, and its registered architecture preserves signal integrity when multiple modules populate the same channel.

At just 1.2 V, the module helps data centers lower power draw and manage thermal output without sacrificing throughput. Installation is straightforward in supported systems—including the SD530, SN550, SN850, SR550, SR630, SR650, SR850, SR950, and ST550—because the part is fully qualified by Lenovo. Once installed, servers gain additional headroom for hosting more virtual machines, accelerating in-memory databases, or smoothing the response of analytics and ERP workloads that rely on fast, consistent access to large data sets.

Whether you are outfitting a new cluster or extending the life of an existing deployment, this Lenovo-engineered memory gives IT teams a simple path to greater capacity and improved reliability without complex tuning or compatibility concerns.
