Overview of the M393A4K40DB2-CTD6Y

The M393A4K40DB2-CTD6Y is a DDR4 memory module from Samsung, specifically designed for server and high-performance computing systems. It has a capacity of 32GB and operates at a speed of 2666 MHz, making it a good choice for applications that require high-speed memory performance. The M393A4K40DB2-CTD6Y is a dual rank x4 configuration, meaning it has four memory chips spread across two ranks, which can improve memory performance in certain situations. The M393A4K40DB2-CTD6Y also has Error Correction Code (ECC) technology built in, which helps detect and correct any memory errors, making it ideal for use in mission-critical systems. The M393A4K40DB2-CTD6Y is a registered memory module, which means it includes a register chip that temporarily holds data before it is sent to the memory controller, helping to reduce electrical loading and improve performance. The M393A4K40DB2-CTD6Y is a 288-pin DIMM and requires a system and motherboard that supports DDR4 memory.

DDR4 technology used in the M393A4K40DB2-CTD6Y

The M393A4K40DB2-CTD6Y uses DDR4 (Double Data Rate 4) technology, which is a type of dynamic random access memory (DRAM) used in computer systems. DDR4 is the fourth generation of DDR memory technology and offers several improvements over its predecessor, DDR3, including higher speed, increased memory capacity, and improved power efficiency.

DDR4 operates at higher speeds than DDR3, allowing for faster data transfer and improved system performance. It also supports larger memory capacities and has a reduced voltage requirement, which results in improved power efficiency. Additionally, DDR4 features improved signal integrity, which can reduce the risk of errors and improve overall system stability.

The M393A4K40DB2-CTD6Y is a DDR4 memory module that operates at 2666 MHz, making it suitable for high-performance computing systems that require fast memory performance. The use of DDR4 technology in the M393A4K40DB2-CTD6Y can improve system performance, stability, and power efficiency compared to DDR3 memory.
