Samsung 128GB DDR4 2933 Mbps Server Memory Module

Overview

The Samsung M386AAG40MM2-CVF is a server memory module designed to provide 128GB of DDR4 capacity running at 2933 Mbps. It serves enterprise environments that require large memory pools combined with reliable and efficient performance. Operating at 1.2 volts, this module balances fast data transfer speeds with power efficiency, making it suitable for demanding server workloads.

Its Load Reduced DIMM (LRDIMM) design includes a register and data buffer that reduce electrical load on the memory controller, ensuring stable clock and command signals even when multiple modules share the same channel. This makes it a practical choice for high-density server configurations.

Key features

• Load Reduced DIMM architecture that stabilizes signals for reliable operation in multi-module setups
• High capacity of 128GB to support memory-intensive applications like virtual machine clusters and in-memory databases
• Four rank x4 DRAM organization enabling dense memory configurations with up to three modules per channel
• Standard 288-pin DDR4 interface for easy installation in compatible server motherboards
• Operates at a low voltage of 1.2V to help manage overall server power consumption
• Compatible with legacy systems requiring DDR4 2933 memory, extending hardware lifespan without full platform upgrades
