Samsung 128GB DDR4-3200 PC4-25600 288 pin 1.2 V RDIMM Server Memory Module

The Samsung M393AAG40M32-CAE is a 128GB DDR4 server memory module that operates at 3200 megatransfers per second while drawing just 1.2 volts. Built in a 288-pin registered DIMM format, it slots into server motherboards that need RDIMMs and stable performance under sustained workloads.

An onboard register smooths clock, command, and control signals so the memory controller can manage heavier configurations without signal loss. The 4R x 4 layout, based on three-dimensional stacked chips, fits a full 128GB onto a single stick, allowing administrators to increase capacity without consuming additional slots.

The module adds reliability through ECC with an 8-bit parity architecture that detects and corrects common memory errors. That protection makes it well suited for virtualization hosts, database clusters, analytics engines, and any application that demands uninterrupted uptime.

Install it in platforms that support DDR4-3200 registered memory, up to two DIMMs per channel, and either x4 or x8 organization. Whether you are expanding an existing rack or building a new node for cloud and high-performance computing, this Samsung module provides the headroom needed to run more virtual machines and larger in-memory datasets.
