In description module boasts advanced features like Error Correction Code (ECC), Registered, Dual Rank, and operates at a low voltage of 1.2V. The 288-pin RDIMM form factor makes it compatible with a wide range of server configurations.

Understanding Memory Basics DDR4 SDRAM

Dynamic Random Access Memory (DRAM) is a crucial component in computer systems, providing temporary storage for data and instructions that the CPU needs to access quickly. DDR4 stands for Double Data Rate 4 and represents the fourth generation of DDR memory technology. Its synchronous nature allows for faster data transfer rates compared to previous DDR iterations.

Capacity and Speed 32GB at 3200MHz

The Samsung M393A4K40EB3-CWEBY module offers a hefty capacity of 32GB, enabling servers to handle large volumes of data and numerous applications simultaneously. Operating at a speed of 3200MHz, this memory module ensures rapid access to stored information, enhancing server performance and responsiveness.

Error Correction Code

Error Correction Code (ECC) is a crucial feature in server memory. It enables the detection and correction of common data corruption issues that might occur during data storage or retrieval. ECC ensures data integrity, making this memory module highly reliable for critical server operations where accuracy is paramount.

Registered and Dual Rank Configuration

This Samsung DDR4 module employs a Registered architecture, which adds a buffer to the address and command lines. This buffer helps reduce the electrical load on the memory controller, allowing for more modules to be without compromising stability. The Dual Rank configuration enhances memory performance by interleaving memory banks, facilitating faster data access.

Low Voltage Operation 1.2V

Efficiency and power consumption are critical concerns in server environments. Operating at a low voltage of 1.2V, this DDR4 module not only contributes to energy efficiency but also generates less heat, aiding in an optimal operating temperature within the server.

Compatibility and Form Factor 288-Pin RDIMM

The 288-pin RDIMM form factor of the Samsung M393A4K40EB3-CWEBY ensures compatibility with server systems designed to accommodate DDR4 memory modules. Its design allows for easy configuration within various servers, making it a versatile choice for different server architectures.

Application in Servers

The Samsung M393A4K40EB3-CWEBY memory module is specifically designed for server applications. Servers require robust and reliable memory solutions to handle extensive data processing, multitasking, and continuous operations. This module's features cater to the demanding nature of server environments, ensuring stability, data accuracy, and high performance.

Suitability for Servers

This memory module is specifically designed for servers. Servers require high-performance memory to handle multiple tasks simultaneously, and this module meets those demands.

1.2v Voltage

This memory module operates at a voltage of 1.2 volts. The voltage level determines how much power the memory module needs to function. Lower voltage can mean less power consumption, which is beneficial for energy efficiency.

Improved Server Performance

With its high capacity, faster speed, and error correction capabilities, this RAM module can significantly enhance a server's performance, allowing it to handle complex computations and multitasking efficiently.

Data Integrity

The ECC feature ensures data accuracy by detecting and correcting errors, making this RAM module reliable for critical server operations where data integrity is paramount.

Energy Efficiency

Operating at 1.2 volts, this DDR4 RAM module is designed to consume less power, contributing to energy efficiency and potentially reducing operating costs in the server.


The Samsung M393A4K40EB3-CWEBY 32GB DDR4 memory module significantly enhances a server's performance by facilitating faster data access, retrieval, and processing. This capability is particularly beneficial for servers handling complex computations, database operations, and virtualization tasks.
