DDR4 memory module. Single rank for various desktop PCs. Expand your system with more RAM to achieve a significant increase in performance. With more RAM, you can run more programmes simultaneously, switch between open applications faster and experience fewer delays in daily activities. DDR4 RAM brings some improvements in speed and performance compared to previous generations. A fourth-generation RAM bar has more pins to connect to the board and cope with the higher speed. Each DIMM has a direct line to the CPU controller to avoid delays or bottlenecks in data transfer from the CPU to the RAM. DDR4 also contains innovations that reduce power consumption and increase reliability.
