Product overview for the Samsung M393A4K40BB2-CTD

In the ever-evolving landscape of technology, the efficiency and performance of server systems play a crucial role in meeting the demands of modern computing. One essential component contributing to the seamless operation of servers is the Random Access Memory (RAM). Among the various RAM modules available in the market, the Samsung M393A4K40BB2-CTD 32GB DDR4 stands out as a high-performance and reliable option. In this detailed exploration, we will delve into the specifications, features, and significance of the Samsung M393A4K40BB2-CTD, shedding light on its role in enhancing server capabilities.

Key Specifications

The Samsung M393A4K40BB2-CTD boasts a substantial capacity of 32 gigabytes (GB), providing ample memory space for server applications and data processing. This generous capacity is particularly beneficial for tasks that demand large amounts of data storage and quick retrieval.

Speed: 2666MHz

Operating at a speed of 2666 megahertz (MHz), this memory module ensures swift data transfer and efficient processing. The high speed is vital for handling demanding computational tasks and supporting the overall responsiveness of server systems.


The memory module utilizes DDR4 Synchronous Dynamic Random Access Memory (SDRAM) technology. DDR4 represents the fourth generation of DDR RAM, offering improved performance and energy efficiency compared to its predecessors. This choice of technology signifies a commitment to staying at the forefront of advancements in-memory capabilities.

ECC Registered

Error-correcting code (ECC) is a crucial feature for server memory modules. ECC functionality helps detect and correct errors in data, enhancing the reliability and stability of the system. The Samsung M393A4K40BB2-CTD being ECC registered ensures that it meets high standards for data integrity, making it a dependable choice for server environments where accuracy is paramount.

Dual Rank

The memory module is designed with a dual-rank configuration. Dual-rank modules have two sets of memory banks, allowing for better interleaving and improved performance in certain scenarios. This dual-rank configuration contributes to the efficient multitasking capabilities of the server.

Voltage: 1.2V

Operating at a low voltage of 1.2 volts, this DDR4 module is energy-efficient. Low voltage not only reduces power consumption but also contributes to heat reduction, promoting a cooler operating environment for the server. This aligns with the growing emphasis on sustainability and energy efficiency in contemporary technology.

Form Factor: 288-pin RDIMM

The Samsung M393A4K40BB2-CTD features a 288-pin Registered Dual In-Line Memory Module (RDIMM) form factor. RDIMMs are known for their robust design and enhanced reliability, making them well-suited for server applications where stability is paramount.

Significance for Servers

Enhanced Server Performance

The 32GB capacity, coupled with a speed of 2666MHz, ensures that the Samsung M393A4K40BB2-CTD contributes significantly to enhancing server performance. Servers equipped with this memory module can efficiently handle memory-intensive tasks, such as database management, virtualization, and high-performance computing.

Reliability in Data Integrity

The ECC-registered feature of this memory module plays a pivotal role in maintaining data integrity. In server environments, where data accuracy is non-negotiable, ECC ensures that any potential errors in the memory are identified and corrected, preventing data corruption and system crashes.

Optimal Multitasking

The dual-rank configuration allows for optimal multitasking capabilities. Servers often need to handle multiple processes simultaneously, and the dual-rank design enables efficient data interleaving, reducing bottlenecks and enhancing overall system responsiveness during multitasking scenarios.

Energy Efficiency and Sustainability

Operating at a low voltage of 1.2 volts, the Samsung M393A4K40BB2-CTD aligns with the growing emphasis on energy efficiency and sustainability in the tech industry. Reduced power consumption not only lowers operational costs but also contributes to a greener IT infrastructure.

Robust Design for Server Environments

The 288-pin RDIMM form factor ensures the physical robustness of the memory module. This design is well-suited for the demands of server environments, providing stability and durability. The registered nature of RDIMMs adds an extra layer of reliability, making them a preferred choice for mission-critical applications.

Compatibility with Server Platforms

The Samsung M393A4K40BB2-CTD is designed to be compatible with a range of server platforms. Before installation, it is essential to verify compatibility with the specific server hardware to ensure optimal performance and stability.


Installing the Samsung M393A4K40BB2-CTD memory module follows standard procedures for server memory. However, it is crucial to refer to the manufacturer's guidelines and documentation for the server system to ensure correct installation. Following proper installation practices is essential for maximizing the performance and lifespan of the memory module.
