Samsung 64GB DDR4 2933 Mbps Server Memory Module

Overview

The Samsung M386A8K40CM2-CVF is a server memory module designed to deliver 64 GB of DDR4 capacity with a data transfer rate of 2933 MT/s. It uses Load Reduced DIMM (LRDIMM) technology to maintain signal integrity and reduce power consumption, operating efficiently at 1.2 volts. This module is ideal for high-density server environments where reliability and performance under heavy workloads are critical.

Key features

• Load Reduced DIMM design with an on-board register and data buffer to ensure clean and precise signals even in fully populated systems
• High data rate of 2933 MT/s that balances bandwidth and power efficiency for demanding server applications
• Four-rank by four-bit organization that supports complex memory configurations and enhances compatibility
• 288-pin form factor compatible with a wide range of current server motherboards for easy installation
• Capability to support up to three modules per memory channel, enabling greater memory density and reducing the number of nodes required

Performance and reliability

This memory module is engineered to maintain stable and reliable operation in multi-DIMM server configurations. The inclusion of a register and dedicated data buffer on the module reduces electrical load on the memory controller, which helps prevent signal degradation and errors during heavy workloads. This makes it well suited for environments running virtual machines, in-memory databases, or high-performance computing tasks where uptime and responsiveness are essential.

Ideal uses and environments

The Samsung M386A8K40CM2-CVF fits well in data centers and enterprise servers that require large memory capacities with efficient power consumption. It is a strong choice for IT administrators managing virtualized infrastructures or applications that demand high memory bandwidth and density. Its compatibility with standard DDR4 server boards and support for multiple modules per channel make it a flexible option for both upgrades and new server builds.
