The Samsung M393A2K43BB1-CTD memory module is designed to meet the demanding requirements of server environments. Let's break down its key specifications to understand the capabilities it brings to the table.

Memory Capacity

The module boasts a substantial 16GB of memory capacity, making it suitable for handling memory-intensive tasks in server applications. This ample capacity ensures that the server can run multiple processes concurrently without compromising on performance.

Memory Type and Speed

Built on DDR4 SDRAM technology, this module operates at a speed of 2666MHz, officially classified as PC4-21300. The DDR4 architecture ensures faster data transfer rates, enhancing the overall responsiveness of the server. The 2666MHz speed is particularly beneficial for applications that demand quick data access and processing.

Error Correction and Reliability

Featuring Error-Correcting Code (ECC) technology, the M393A2K43BB1-CTD module is classified as ECC Registered. ECC is a crucial feature for servers as it helps detect and correct errors in the memory, ensuring data integrity. The Registered design adds an extra layer of stability, making the module reliable in mission-critical server environments.

Form Factor and Pin

This memory module adheres to the 288-pin Registered Dual In-Line Memory Module (RDIMM) form factor. The 288-pin configuration is standard for DDR4 memory, ensuring compatibility with a wide range of server systems. The RDIMM design allows for greater stability and reliability compared to other form factors.

Power Efficiency

Operating at a low voltage of 1.2V, the M393A2K43BB1-CTD module is energy-efficient. This not only contributes to lower power consumption but also helps in heat dissipation, making it an environmentally friendly and temperature-conscious choice for server setups.


Now that we've explored the technical specifications, let's delve into the features that set the Samsung M393A2K43BB1-CTD apart as a preferred memory module for server applications.

High Performance

The 2666MHz speed of this memory module ensures high performance, making it ideal for applications that demand quick data access and processing. Whether it's handling complex calculations, database operations, or virtualization tasks, the module's high performance contributes to an overall smoother server experience.

ECC for Data Integrity

The incorporation of Error-Correcting Code (ECC) is a standout feature, especially in server environments where data accuracy is paramount. ECC technology helps identify and rectify errors in real time, preventing potential data corruption that could lead to system crashes or data loss.

Registered Design for Stability

The Registered (RDIMM) design of the module enhances stability by buffering memory commands. This feature is particularly beneficial in scenarios where multiple modules are installed, as it helps reduce the electrical load on the server's memory controller. The result is a more stable and reliable system.


With a 16GB capacity, the M393A2K43BB1-CTD offers scalability for server configurations. Servers often require expansion to accommodate growing workloads, and the ability to scale up the memory capacity is a crucial consideration. This module provides flexibility for future upgrades, ensuring that the server can adapt to changing requirements.


The 288-pin RDIMM form factor ensures compatibility with a wide range of server systems. Compatibility is a key factor when choosing memory modules, as it determines whether the module can seamlessly integrate with the existing server infrastructure. The standardized form factor of the M393A2K43BB1-CTD enhances its compatibility, making it a versatile choice for various server setups.

Benefits for Server Environments

Now that we've explored the specifications and features, let's examine the tangible benefits that the Samsung M393A2K43BB1-CTD 16GB DDR4 memory module brings to server environments.

Improved Server Responsiveness

The high-speed operation of 2666MHz contributes to improved server responsiveness. In applications where quick data access is crucial, such as financial transactions or real-time analytics, the M393A2K43BB1-CTD ensures that the server can handle tasks with efficiency, reducing latency and enhancing user experience.

Enhanced Reliability

The ECC Registered design of the module significantly enhances reliability. By detecting and correcting errors in real time, the module prevents potential data corruption, ensuring that the server operates reliably even under heavy workloads. This is particularly critical in mission-critical applications where downtime or data inaccuracies are unacceptable.

Optimal Performance in Multi-Module

The Registered design not only contributes to stability but also ensures optimal performance in scenarios where multiple memory modules are installed. As servers scale to meet increased demands, the M393A2K43BB1-CTD maintains consistent performance, making it suitable for both small-scale and enterprise-level server configurations.

Energy Efficiency

Operating at a low voltage of 1.2V, the module promotes energy efficiency. In data centers and server rooms where power consumption is a significant consideration, the M393A2K43BB1-CTD helps in reducing overall energy costs. The lower voltage also contributes to heat dissipation, potentially extending the lifespan of the server components.

Future-Proofing with Scalability

The 16GB capacity of the module provides ample room for future expansion. Server environments are dynamic, and the ability to scale up memory capacity is essential to accommodate evolving workloads. The M393A2K43BB1-CTD allows for seamless scalability, ensuring that the server can adapt to changing demands without the need for a complete overhaul.

Easy Integration

The standardized 288-pin RDIMM form factor simplifies the integration of the M393A2K43BB1-CTD into existing server setups. This ease of integration streamlines the installation process, reducing downtime during upgrades or replacements. Additionally, the module's reliability minimizes the need for frequent contributing to overall system stability.
