More Information for Samsung M386AAG40AM3-CWELQ

In the ever-evolving landscape of technology, memory modules play a crucial role in determining the performance and efficiency of servers. One such memory module that stands out is the Samsung M386AAG40AM3-CWELQ, a 128GB DDR4 LRDIMM (Load-Reduced Dual In-Line Memory Module). In this detailed guide, we will delve into the specifics of this memory module, breaking down its key features and specifications.

Introduction to Samsung M386AAG40AM3-CWELQOverview

The Samsung M386AAG40AM3-CWELQ is a high-capacity DDR4 memory module designed for server applications. It boasts a massive 128 gigabytes (GB) of storage, making it suitable for handling demanding workloads in server environments.

DDR4 Technology

This memory module utilizes DDR4 technology, which represents the fourth generation of Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM). DDR4 offers improved performance, higher data transfer rates, and increased energy efficiency compared to its predecessors.

Technical SpecificationsCapacity and Speed

The M386AAG40AM3-CWELQ comes equipped with a substantial 128GB storage capacity. Its operating speed is an impressive 3200 megahertz (MHz), indicating the rate at which data can be transferred between the memory module and the processor.

PC4-25600 and CL22

The module is classified as PC4-25600, signifying its peak bandwidth in megabytes per second. The term CL22 refers to the CAS Latency, which is the time it takes for the memory to respond to a command. A lower CAS Latency generally indicates faster response times.

Error Correction Code (ECC)

This memory module incorporates Error Correction Code (ECC), a critical feature for servers where data integrity is paramount. ECC helps identify and correct errors in data, ensuring the reliability of stored information.

Registered and Quad Rank

Being a Registered memory module, the M386AAG40AM3-CWELQ includes a register between the RAM modules and the system's memory controller. This helps enhance stability and allows for larger memory configurations. Additionally, it is Quad Rank, meaning it has four independent ranks of memory banks, contributing to increased memory density.

X4 Organization

The memory module follows a Quad Rank X4 organization, where each rank is organized as four banks of memory cells. This organizational structure aids in optimizing data access and retrieval processes.

1.2V Operating Voltage

Operating at a low voltage of 1.2 volts, this DDR4 LRDIMM is designed for energy efficiency, contributing to reduced power consumption and heat generation. This is particularly crucial in server environments where power efficiency is a key consideration.

288-Pin LRDIMM Form Factor

The module features a 288-pin Load-Reduced Dual In-Line Memory Module (LRDIMM) form factor. The LRDIMM design allows for greater memory capacity by reducing the electrical load on the memory bus.

Application in ServersServer Compatibility

The Samsung M386AAG40AM3-CWELQ is specifically designed for server applications, catering to the demands of data centers, cloud computing, and other enterprise-level environments. Its high capacity and error-correcting capabilities make it ideal for handling mission-critical tasks.

Performance Boost

With a speed of 3200MHz and advanced features like ECC and Quad Rank organization, this memory module contributes to improved server performance. Faster data transfer rates and error correction mechanisms ensure that the server operates efficiently and reliably.


The Registered and Quad Rank features to enhance the scalability of server memory configurations. Servers can accommodate larger amounts of memory, allowing for increased virtualization, data processing, and multitasking capabilities.
