Product Overview of the Samsung M393A8K40B21-CTC

M393A8K40B21-CTC is a high-capacity memory module manufactured by Samsung that is designed specifically for servers. It is a DDR4 SDRAM module with an ECC Registered Quad Rank X4 configuration that delivers high-speed performance and reliability. In this article, we will take an in-depth look at the features and benefits of the Samsung M393A8K40B21-CTC memory module.

Memory Capacity and Speed

The M393A8K40B21-CTC module has a total capacity of 64GB, which is suitable for use in high-performance server environments that require a large amount of memory. It operates at a speed of 2400MHz and has a PC4-19200 rating. This means that it can deliver data transfer rates of up to 19.2GB/s, which is significantly faster than DDR3 memory.

Memory Type and Form Factor

The Samsung M393A8K40B21-CTC is a DDR4 memory module, which is the latest and most advanced type of memory available for servers. It is designed to provide faster data transfer rates, lower power consumption, and improved reliability compared to DDR3 memory. The module has a 288-pin LRDIMM form factor, which is a type of memory module that is designed to provide maximum memory density and reliability for server applications.

ECC Registered Memory

The M393A8K40B21-CTC module is ECC (Error-Correcting Code) Registered memory. This means that it has built-in error detection and correction capabilities that help to ensure data integrity. ECC memory is particularly important for server applications, as it helps to prevent errors that can cause data corruption, system crashes, and other problems.

Quad Rank X4

The M393A8K40B21-CTC module has a Quad Rank X4 configuration. This means that it has four banks of memory chips, each of which is 4 bits wide. The X4 designation refers to the fact that each memory chip has four independent memory banks. The Quad Rank configuration allows the module to support a high-density memory design, which is ideal for use in servers that require large amounts of memory.

LRDIMM Technology

The M393A8K40B21-CTC module uses LRDIMM (Load Reduced Dual Inline Memory Module) technology. This technology allows the module to reduce the load on the server's memory bus, which can help to improve system performance. LRDIMMs also provide higher memory capacity and lower power consumption compared to other memory technologies, making them an ideal choice for high-performance server applications.


The M393A8K40B21-CTC module is designed to be compatible with a wide range of server systems that support DDR4 memory. It is particularly suited for use in high-performance server applications that require large amounts of memory. The module is also compatible with a variety of operating systems, including Windows, Linux, and UNIX.
