Samsung 128GB DDR4 3200MHz PC4-25600 ECC LRDIMM 4Rx4 Memory Module

The Samsung M386AAG40AM3-CWE is a 128GB DDR4 server memory module that combines high capacity with dependable speed. As a Load Reduced DIMM, it relies on an onboard register and data buffer to ease the electrical load on the memory controller, maintaining clear signals even when many modules sit on the same channel.

Operating at 3200MHz (PC4-25600), the module delivers the bandwidth required by multicore processors that handle virtualization, large databases, and real time analytics. Error Correcting Code continuously scans for and corrects single bit errors, adding resilience for workloads that demand constant uptime.

The design follows JEDEC standards, runs at 1.2 volts, and fits the common 288 pin slot found on server motherboards built for LRDIMM technology. Installation is straightforward: press the module into an available slot, confirm BIOS recognition, and the additional 128GB capacity is ready to use.

Data center teams use this module to consolidate virtual machines, expand in memory cache sizes, and shorten response times in high performance computing clusters. Any environment that needs more memory per slot, without sacrificing stability, will benefit from the Samsung M386AAG40AM3-CWE.
