Samsung 128GB DDR4 2933 Mbps Server Memory Module

The Samsung M386AAG40MM2-CVF is a server memory module with 128GB of DDR4 capacity, engineered for enterprise systems that need both large memory footprints and dependable performance. It operates at 2933 Mbps and 1.2 volts, delivering quick data transfer while keeping power demands within typical server limits.

Because it follows the Load Reduced DIMM approach, the module contains a register and a data buffer that ease the electrical load on the memory controller. This stabilization helps maintain clean clock and command signals when several modules share the same channel, a common requirement in high density servers.

The memory is arranged as four ranks of x4 DRAM, allowing administrators to reach very high total capacity in configurations that support up to three modules per channel. The 288 pin layout slips straight into any compatible DDR4 LRDIMM slot, so no additional hardware or firmware changes are required.

In practical terms, this module is a solid choice for virtual machine clusters, in memory databases, large scale analytics, or any workload where gigabytes of fast, low latency memory directly influence throughput. It is also valuable for organizations that must maintain or replace legacy hardware which still runs on DDR4 2933 parts that have reached end of life.

By combining high density, stable signaling, and straightforward installation, the Samsung M386AAG40MM2-CVF helps IT teams extend the life of critical servers or expand existing capacity without a full platform refresh.
