Product overview for the Samsung M386A8K40BM2-CTD

In the realm of server memory, Samsung has made a significant mark with its M386A8K40BM2-CTD 64GB DDR4 memory module. This intricate piece of hardware is tailored to meet the demanding requirements of servers, offering a substantial 64GB capacity with advanced features such as ECC (Error-Correcting Code), Registered design, and a Quad Rank structure. In this comprehensive exploration, we will delve into the various aspects of this memory module, unraveling its specifications, functionality, and the benefits it brings to server performance.

Key Specifications

Capacity and Speed

The Samsung M386A8K40BM2-CTD boasts a formidable 64GB capacity, making it suitable for memory-intensive applications and workloads. Operating at a speed of 2666MHz, this DDR4 module aligns with the PC4-21300 standard, ensuring a balance between high-speed data processing and stability.

Error-Correcting Code (ECC)

One of the standout features is ECC, a crucial attribute in server memory. ECC is designed to identify and correct single-bit errors, enhancing the module's reliability. In a server environment where data integrity is paramount, ECC plays a pivotal role in preventing potential data corruption.

Registered Design

The memory module employs a Registered design, denoted by the 'R' in RDIMM. Registered memory includes a buffer between the memory controller and the RAM modules, reducing the electrical load on the memory controller. This results in increased system stability and the ability to support larger memory capacities.

Quad Rank

The Quad Rank X4 signifies the organization of memory banks on the module. In a quad-rank setup, the memory is divided into four separate ranks, allowing for efficient data access and manipulation. This configuration is particularly advantageous in scenarios where multiple tasks are executed simultaneously, contributing to overall system performance.

Voltage and Form Factor

Operating at a low voltage of 1.2V, the M386A8K40BM2-CTD aligns with energy efficiency standards. The 288-pin LRDIMM (Load-Reduced DIMM) form factor ensures compatibility with a wide range of server architectures while also contributing to better thermal performance.

Functionality and Performance

Server Optimization

Designed explicitly for server environments, this Samsung DDR4 module is optimized to deliver high-performance computing. The 64GB capacity caters to memory-intensive applications such as virtualization, database management, and other server workloads.

Stability and Reliability

The integration of ECC ensures that the memory module can detect and rectify errors in real time. In a server ecosystem where downtime is a critical concern, ECC functionality enhances system stability, minimizes crashes, and safeguards against potential data corruption.

Multi-Tasking Capabilities

The Quad Rank X4 configuration enhances the module's ability to handle multiple tasks concurrently. This is particularly beneficial in scenarios where servers are tasked with running numerous applications simultaneously or managing virtualized environments with varying workloads.

Reduced Load on Memory Controller

The Registered design contributes to reducing the electrical load on the memory controller. By incorporating a buffer, the memory module can support larger capacities without compromising system stability. This is vital for servers handling extensive datasets and complex computational tasks.

Energy Efficiency

Operating at a low voltage of 1.2V, the memory module aligns with energy-efficient standards. This not only contributes to reduced power consumption but also aids in maintaining optimal thermal conditions within the server chassis.

Advantages in Server Environments

Enhanced Data Integrity

The ECC feature actively monitors and corrects errors, ensuring that data integrity is maintained. This is critical in server environments where the loss or corruption of data can have severe consequences.


The Registered design allows for greater scalability by reducing the load on the memory controller. Servers can seamlessly scale their memory capacity without compromising on stability.

Performance Boost

The combination of a high-speed operation at 2666MHz and the Quad Rank configuration contributes to a notable performance boost. Servers experience improved responsiveness and efficiency in handling complex computational tasks.


The 288-pin LRDIMM form factor ensures compatibility with a wide range of server configurations. This versatility makes the Samsung M386A8K40BM2-CTD an ideal choice for various server architectures and setups.
