Description
Low power consumption
The Samsung M391A1K43BB2-CTD memory module is designed to have low power consumption, making it an ideal choice for use in mobile devices and other systems that require energy efficiency. There are several features of this memory module that contribute to its low power consumption:
- DDR4 Technology: The M391A1K43BB2-CTD module uses DDR4 technology, which is more energy-efficient than previous generations of memory. DDR4 memory requires less voltage to operate, which results in lower power consumption.
- Low Voltage: The M391A1K43BB2-CTD module operates at a low voltage of 1.2V, which is lower than the 1.5V or 1.65V required by some older memory modules. This lower voltage results in lower power consumption.
- Power-Saving Features: The M391A1K43BB2-CTD module also includes power-saving features that help to reduce power consumption even further. For example, the module includes a feature called Auto Temperature Compensation (ATC) that adjusts the voltage based on temperature, which helps to reduce power consumption.
- Green Memory: Samsung has also developed a program called Green Memory that promotes the use of energy-efficient memory modules like the M391A1K43BB2-CTD. The program includes various initiatives to reduce power consumption and improve environmental sustainability.
Capacity and speed
The Samsung M391A1K43BB2-CTD is a DDR4 SDRAM memory module designed for use in desktop computers or servers. This memory module has a capacity of 8GB and a clock speed of 2400MHz, also known as PC4-19200.
Capacity: The capacity of a memory module refers to the amount of data that it can store and access. The M391A1K43BB2-CTD has a capacity of 8GB, which is considered to be a mid-range capacity for memory modules. This capacity is suitable for general computing tasks, such as web browsing, office productivity, and light gaming.
Speed: The clock speed of a memory module refers to how quickly it can transfer data to and from the processor. The M391A1K43BB2-CTD has a clock speed of 2400MHz, which is a relatively fast speed that can handle most computing tasks. This speed is also known as PC4-19200, which refers to the maximum data transfer rate of 19.2GB/s.
Voltage and power consumption
The Samsung M391A1K43BB2-CTD memory module is a DDR4 SDRAM module that operates at a voltage of 1.2V. This is the standard voltage for DDR4 memory modules, and it allows for lower power consumption compared to earlier generations of DDR memory.
Lower voltage means lower power consumption, which is an important consideration for energy-efficient systems and servers. With lower power consumption, the M391A1K43BB2-CTD module can help reduce overall energy costs and can help to increase the lifespan of the memory module.
The power consumption of the memory module is typically measured in terms of watts (W). The power consumption of the M391A1K43BB2-CTD memory module varies depending on the operating frequency and the number of ranks.
For example, at the maximum operating frequency of 2400MHz, the power consumption of the M391A1K43BB2-CTD memory module is typically around 2.88W. However, at a lower frequency of 2133MHz, the power consumption is around 2.16W. The power consumption of the memory module can be further reduced by enabling power-saving features in the system BIOS.
