M393A2K40BB1-CTD Samsung 16GB 1X16GB 2666MHz PC4-21300 CL19 ECC Registered 1RX4 1.2V DDR4 SDRAM 288-PIN DIMM Samsung Memory Module For Server. New Bulk Pack.

M393A2K40BB1-CTD is a memory module produced by Samsung, one of the world’s leading technology companies. It is a 16GB DDR4 SDRAM memory module that operates at a clock speed of 2666MHz (PC4-21300) and a voltage of 1.2V. This memory module is designed for use in servers and workstations that require high performance and reliability.

DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) is the fourth generation of the DDR SDRAM memory technology. DDR4 offers several improvements over its predecessor, DDR3, including higher data transfer rates, lower power consumption, and higher memory capacities. DDR4 also uses a higher number of banks and ranks, allowing for higher memory density and larger memory modules.

The M393A2K40BB1-CTD memory module is an ECC (Error Correcting Code) Registered module. ECC is a type of memory that includes additional bits to detect and correct errors that may occur during data transmission. This feature makes ECC memory more reliable than non-ECC memory, which is especially important in critical applications such as servers and workstations.

Registered memory, on the other hand, is a type of memory that includes a buffer between the memory controller and the memory modules. This buffer helps reduce the electrical load on the memory controller, allowing for more memory modules to be connected to the system without causing signal integrity issues.

In summary, the M393A2K40BB1-CTD Samsung 16GB DDR4 SDRAM is a high-performance, reliable memory module designed for use in servers and workstations. It offers a high data transfer rate, lower power consumption, and error-correcting capabilities, making it an ideal choice for critical applications that require high performance and reliability.

Understanding the Memory Technology: DDR4 SDRAM

DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) is the fourth generation of DDR SDRAM technology, which is the most common type of memory used in modern computers. DDR4 was introduced in 2014 as the successor to DDR3 and offers several improvements over its predecessor.

One of the key improvements in DDR4 technology is higher data transfer rates. DDR4 memory modules can transfer data at speeds ranging from 2133MHz to 4800MHz, which is significantly faster than the maximum transfer rate of 2133MHz for DDR3 modules. The higher transfer rates in DDR4 allow for faster processing of large amounts of data, which is particularly useful in applications such as gaming, video editing, and scientific computing.

Another important improvement in DDR4 technology is lower power consumption. DDR4 memory modules operate at a lower voltage than DDR3 modules, with a standard voltage of 1.2V compared to the 1.5V used in DDR3. This reduction in voltage results in lower power consumption and less heat generation, which is beneficial for reducing system heat and power requirements.

DDR4 also supports higher memory capacities than DDR3. While DDR3 was limited to a maximum capacity of 8GB per module, DDR4 can support up to 16GB per module, with some modules capable of supporting up to 32GB. The higher memory capacities in DDR4 allow for greater flexibility in system design and the ability to handle larger amounts of data.

Finally, DDR4 also includes some other improvements such as improved signal integrity, better reliability, and higher density. DDR4 memory modules have a higher number of banks and ranks, which allows for higher memory density and larger memory modules. They also include some new features such as CRC (Cyclic Redundancy Check) to detect and correct errors during data transmission, which further improves system reliability.

Features and Benefits of ECC Registered Memory

ECC (Error Correcting Code) memory is a type of memory that includes additional bits to detect and correct errors that may occur during data transmission. ECC memory is commonly used in critical applications such as servers, workstations, and scientific computing, where data accuracy and system reliability are of utmost importance. Here are some features and benefits of ECC registered memory:

• Error Detection and Correction: ECC memory includes additional bits that allow the memory controller to detect and correct errors that may occur during data transmission. This feature ensures that data is transmitted accurately and without errors, which is critical in applications that require high data accuracy.
• Improved System Reliability: The error correction capabilities of ECC memory make it more reliable than non-ECC memory. In critical applications such as servers and workstations, system reliability is essential, and any data errors can lead to system crashes or data corruption. ECC memory helps ensure that data is transmitted accurately and without errors, improving system reliability.
• Reduced Risk of System Failure: By detecting and correcting errors, ECC memory reduces the risk of system failure due to data errors. This is particularly important in applications such as medical equipment, where system failure can have severe consequences.
• Lower Total Cost of Ownership: While ECC memory is generally more expensive than non-ECC memory, it can lead to lower total cost of ownership over the long term. The improved system reliability and reduced risk of system failure can result in lower maintenance costs and fewer system downtime.
• Compatibility with Registered Memory: ECC memory is often available in registered configurations, which include a buffer between the memory controller and the memory modules. This buffer helps reduce the electrical load on the memory controller, allowing for more memory modules to be connected to the system without causing signal integrity issues.
