Introduction to Samsung M393A2K40CB2

The Samsung M393A2K40CB2-CTD is a high-performance memory module designed for use in servers and data centers. It is a DDR4 SDRAM module that operates at a frequency of 2666MHz, with a CL19 latency and a voltage of 1.2V. The memory module is a registered ECC (Error-Correcting Code) DIMM (Dual In-line Memory Module) and has a capacity of 16GB.

The primary function of a memory module is to store and retrieve data quickly and efficiently. Servers and data centers require large amounts of high-speed memory to perform complex operations such as data analysis, virtualization, and cloud computing. The Samsung M393A2K40CB2-CTD is designed to meet these requirements, providing a reliable and high-performance memory solution for these critical applications.

The memory module uses advanced ECC technology to detect and correct errors in real-time, ensuring data accuracy and system stability. It also features a 288-pin RDIMM form factor, which is designed to work in conjunction with the server's memory controller to deliver maximum performance.

In summary, the Samsung M393A2K40CB2-CTD memory module is a high-quality and reliable memory solution for servers and data centers. Its advanced features and high-speed performance make it an ideal choice for applications that require large amounts of memory and high-speed data processing capabilities.

Understanding ECC Registered Memory and its Benefits

ECC (Error-Correcting Code) memory is a type of computer memory that is designed to detect and correct errors in real-time. This technology is particularly useful in server and data center environments where data accuracy and system stability are critical.

ECC memory works by adding an extra bit to each memory cell, which is used to store parity information. This parity bit is used to check for errors in the data when it is read from or written to the memory cell. If an error is detected, the memory controller can use the parity information to correct the error automatically.

Registered memory, also known as buffered memory, is another type of memory that is commonly used in server and data center environments. It works by adding a register between the memory module and the memory controller. This register acts as a buffer, reducing the electrical load on the memory controller and allowing for larger amounts of memory to be installed in a single system.

ECC registered memory, therefore, combines the benefits of both ECC and registered memory technologies. It provides the error detection and correction capabilities of ECC memory and the buffering capabilities of registered memory, delivering a reliable and high-performance memory solution for servers and data centers.

The benefits of ECC registered memory include:

  • Improved data accuracy: ECC technology detects and corrects errors in real-time, ensuring that data is accurate and reliable.
  • Increased system stability: ECC memory helps to prevent crashes and system failures by detecting and correcting errors before they cause serious problems.
  • Reduced downtime: With ECC memory, there is less downtime due to memory-related errors, as the errors are detected and corrected automatically.
  • Better system performance: Registered memory reduces the electrical load on the memory controller, allowing for larger amounts of memory to be installed and improving overall system performance.

Single Rank vs. Dual Rank Memory Modules

Single Rank and Dual Rank are terms used to describe the organization of memory chips on a memory module. The organization of memory chips can affect the performance and compatibility of the memory module with different motherboards.

Single Rank memory modules have memory chips on only one side of the module and the memory controller accesses all the chips in a linear fashion. Single Rank modules are usually less expensive than Dual Rank modules and can provide better performance when installed in systems with limited memory slots or less than 8GB of memory. Single Rank memory modules are also more compatible with a wider range of motherboards.

Dual Rank memory modules have memory chips on both sides of the module, which are accessed by the memory controller in a parallel fashion. Dual Rank modules provide higher memory density and larger memory capacity than Single Rank modules, allowing for up to 32GB of memory per module. Dual Rank modules are usually more expensive than Single Rank modules but can provide better performance in systems with more than 8GB of memory.

The choice between Single Rank and Dual Rank memory modules depends on the specific requirements of the system. Some motherboards may not be compatible with Dual Rank memory modules or may only support a limited number of Dual Rank modules. In such cases, Single Rank memory modules may be the only option. On the other hand, if a system requires more than 8GB of memory and supports Dual Rank modules, then Dual Rank modules can provide better performance.
