Additional Details:

The M391A1K43DB2-CWE memory module operates at a frequency of 2666MHz, which translates to fast data transfer rates. This helps in improving the overall performance of the system. Its ECC capability is vital in applications where data accuracy is paramount. The 1.2V operating voltage is in line with the DDR4 standard, leading to lower power consumption and reduced heat generation. The 288-pin DIMM form factor ensures compatibility with a wide range of motherboards designed for DDR4 memory.

The module's 8GB capacity provides ample memory for running multiple applications and handling moderate workloads. The high-speed DDR4 interface minimizes memory bottlenecks, resulting in smoother and more responsive system performance. The ECC feature detects and corrects single-bit errors, preventing data corruption and maintaining system stability. This memory module provides a reliable and efficient solution for users seeking a balance between capacity, speed, and data integrity. The CL19 latency indicates the delay between the time a memory request is issued and the time the data is available; a lower latency generally results in better performance. The module is built to meet industry standards, ensuring compatibility and reliability.
