Product Overview

Memory modules are essential components in a computer system, responsible for storing and retrieving data. The M393A2G40DB0-CPB is a memory module made by Samsung, specifically designed for use in servers. In this article, we will explore the technical specifications of the M393A2G40DB0-CPB memory module in detail, including its capacity, clock speed, and other features. We will also examine the benefits of using this memory module in a server environment.


The M393A2G40DB0-CPB memory module has a capacity of 16GB, which is a considerable amount of memory for a server. This memory module is ideal for high-performance computing tasks that require a lot of memory, such as data analysis, virtualization, and scientific computing.

Clock Speed & ECC Registered

The clock speed of a memory module is the rate at which it can transfer data. The M393A2G40DB0-CPB memory module has a clock speed of 2133mhz, which means it can transfer data at a rate of 2133 million cycles per second. This clock speed is relatively high, which makes the memory module suitable for high-performance computing tasks.

ECC stands for Error-Correcting Code. ECC memory is a type of memory that can detect and correct errors that occur during data transfer. This type of memory is crucial for servers because errors can cause system crashes, data corruption, and other issues.

The M393A2G40DB0-CPB memory module is ECC registered, which means it has built-in error detection and correction capabilities. This feature ensures that the data stored on the memory module is accurate and reliable.

Dual Rank

The term "rank" refers to the number of memory chips on a memory module. The more ranks a module has, the more memory it can store. The M393A2G40DB0-CPB memory module is a dual-rank module, which means it has two ranks of memory chips.

Dual-rank memory modules can improve memory performance because they allow the system to access two sets of memory chips simultaneously. This feature can increase the memory bandwidth and reduce latency, resulting in faster data transfer rates.

The CL rating of a memory module refers to its CAS (Column Address Strobe) latency. CAS latency is the time it takes for the memory module to respond to a memory request. A lower CL rating indicates a faster response time.

The M393A2G40DB0-CPB memory module has a CL rating of 15, which is relatively low. This low CL rating means that the memory module can respond to memory requests quickly, which can improve overall system performance.


The M393A2G40DB0-CPB memory module uses DDR4 SDRAM, which stands for Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory. DDR4 is the latest generation of memory technology, and it offers several advantages over its predecessors.

One of the most significant advantages of DDR4 is its lower power consumption. The M393A2G40DB0-CPB memory module operates at a voltage of 1.2 volts, which is lower than the voltage used by DDR3 memory modules. This lower voltage translates into lower power consumption, which is essential for servers that need to run 24/7.

The M393A2G40DB0-CPB memory module is a DIMM, which stands for Dual Inline Memory Module. DIMMs are a type of memory module that have pins on both sides of the module, allowing them to communicate with the motherboard of the server.
