Product overview for the Samsung M386A8K40BM2-CTD

In the realm of server hardware, the choice of memory modules plays a pivotal role in ensuring optimal performance. Among the myriad options available, the Samsung M386A8K40BM2-CTD 64GB DDR4 ECC Registered LRDIMM Memory Module stands out as a formidable choice. In this detailed review, we will delve into the various aspects of this memory module, from its technical specifications to its practical applications in server environments.

Breaking Down the Specifications

Capacity (64GB)

The Samsung M386A8K40BM2-CTD boasts an impressive 64GB capacity Memory Module, making it ideal for memory-intensive applications in server environments. This substantial capacity caters to the demands of modern servers, allowing them to handle complex tasks efficiently.

DDR4 SDRAM Technology

The DDR4 Synchronous Dynamic Random-Access Memory (SDRAM) technology employed in this module represents the latest standard in memory modules. DDR4 offers improvements in speed, efficiency, and overall performance compared to its predecessors, making it a suitable choice for contemporary server configurations.

Speed (2666MHz)

Clocking in at 2666MHz, the memory module provides a high data transfer rate, ensuring swift and responsive performance. This is particularly beneficial for servers running resource-intensive applications, as it reduces latency and enhances overall system responsiveness.

CAS Latency (CL19)

The CAS latency of 19 cycles further contributes to the module's efficiency. CAS latency measures the delay between the time a memory controller requests data and when it is available, and a lower CAS latency indicates faster data access. The CL19 rating of this module aligns with the requirements of server applications demanding quick data retrieval.

ECC (Error-Correcting Code)

Error correction is a critical feature in server environments where data integrity is paramount. The ECC technology in this module detects and corrects single-bit errors, minimizing the risk of data corruption. This ensures the reliability of the server's memory subsystem, a crucial aspect in mission-critical applications.

Registered and Quad Rank

Being a Registered DIMM (RDIMM) and Quad Rank module, this Samsung memory is designed to enhance stability and scalability. The registered design buffers the address and control signals, reducing the load on the memory controller and allowing for larger memory configurations. The Quad Rank configuration enables efficient use of memory slots, making it an excellent choice for servers with limited slots.

Voltage (1.2V)

Operating at a low voltage of 1.2V, this memory module contributes to energy efficiency and minimizes heat generation. Lower power consumption is a significant advantage in server environments where multiple modules are operational, as it reduces the overall power footprint and helps maintain a cooler operating environment.

Form Factor (288-pin LRDIMM)

The 288-pin LRDIMM form factor ensures compatibility with a wide range of server motherboards. This form factor is a standard in the industry, providing ease of integration and upgradability for server administrators.

Practical Applications

The Samsung M386A8K40BM2-CTD 64GB DDR4 ECC Registered LRDIMM Memory Module finds its application in diverse server environments, ranging from enterprise data centers to cloud infrastructure. Its high capacity, combined with ECC and registered features, makes it suitable for the following scenarios:

Data-Centric Applications

The 64GB capacity and high data transfer rate make this module ideal for data-centric applications, such as database management systems, where large datasets need to be processed efficiently.


In virtualized environments, where multiple virtual machines coexist on a single physical server, the high capacity and error-correcting capabilities of this module contribute to the stability and reliability of the overall system.

Scientific and engineering computing

Servers used for scientific simulations, engineering calculations, and other computationally intensive tasks benefit from the high-speed data access and large memory capacity provided by this module.

Financial Services

In financial institutions handling complex calculations and data analytics, the combination of high capacity and error correction ensures the integrity of financial data and transactions.

Cloud Computing Infrastructure

Cloud service providers can leverage the scalability of this module in their infrastructure to meet the varying demands of virtualized instances and applications.
