Description
Introduction to Samsung M393A1K43DB2
The Samsung M393A1K43DB2-CWE memory module is a high-performance DDR4 SDRAM memory module designed for use in server environments. This memory module is specifically engineered to offer reliable performance, high capacity, and fast data transfer rates for server applications that demand high-performance memory.
The module features a capacity of 8GB, which is suitable for many server applications. The 3200MHz memory clock speed and PC4-25600 data transfer rate provide fast data transfer rates, enabling the server to handle large data sets and multiple concurrent operations efficiently.
This memory module is built using ECC (Error-Correcting Code) registered technology, which helps to detect and correct errors in data transmission. This feature makes the memory module highly reliable, especially in environments where data integrity is essential.
The Samsung M393A1K43DB2-CWE memory module is compatible with motherboards that support DDR4 SDRAM memory technology, and it is designed to be easy to install. It features a standard 288-pin RDIMM form factor, making it compatible with most server motherboards.
DDR4 SDRAM Technology
DDR4 SDRAM technology is the fourth generation of double data rate synchronous dynamic random access memory (SDRAM) technology. It is an improvement over the previous DDR3 SDRAM technology in terms of higher bandwidth, lower power consumption, and increased memory capacity.
One of the key improvements of DDR4 SDRAM over DDR3 SDRAM is its higher data transfer rates. DDR4 SDRAM offers faster clock speeds, which enables higher bandwidths and faster data transfer rates. DDR4 SDRAM has a base clock speed of 2133 MHz and can operate up to 4800 MHz or more, while DDR3 SDRAM has a base clock speed of 800 MHz and can operate up to 2133 MHz.
DDR4 SDRAM also operates at a lower voltage than DDR3 SDRAM, which leads to lower power consumption. DDR3 SDRAM operates at 1.5 volts, while DDR4 SDRAM operates at 1.2 volts. This reduction in voltage results in lower power consumption and cooler operation, which is especially important in server environments where power consumption and heat dissipation are critical considerations.
Another key improvement of DDR4 SDRAM is its increased memory capacity. DDR4 SDRAM memory modules can have a maximum capacity of 128GB, which is four times the maximum capacity of DDR3 SDRAM memory modules. This increased capacity is due to the use of higher-density memory chips, which enables more memory to be packed into a single memory module.
Understanding ECC Registered Memory
ECC (Error-Correcting Code) registered memory is a type of memory module that is commonly used in server environments where data integrity is essential. ECC registered memory modules are designed to detect and correct single-bit errors that may occur during data transmission.
Single-bit errors are the most common type of memory error and occur when a bit in the memory module is flipped due to various reasons such as electrical interference, cosmic rays, or aging. These errors can result in incorrect data being stored or retrieved, which can lead to system crashes or data corruption.
ECC registered memory works by adding an extra bit of data to each memory word that is stored in the memory module. This extra bit of data is used to check whether the data has been transmitted correctly. If a single-bit error occurs during data transmission, the ECC circuitry in the memory module detects the error and corrects it before the data is written to or read from the memory module.
Registered memory, on the other hand, is a type of memory module that uses a register between the memory controller and the memory chips. The register acts as a buffer, allowing the memory module to operate at higher frequencies and lower power consumption. This results in improved system stability and performance.
Combining ECC and registered technologies, ECC registered memory offers a higher level of data integrity, reliability, and system stability. In server environments, where data integrity is critical, ECC registered memory is the preferred choice of memory module. However, it is important to note that ECC registered memory is typically more expensive than non-ECC memory modules, and not all systems support it.
