With more RAM, you can run more programs simultaneously, switch between open applications faster, and experience less lag during daily activities. DDR4 brings several improvements in terms of speed and performance compared to previous generations. A fourth-generation RAM stick has more pins to connect to the motherboard, accommodating the higher speeds. 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 includes innovations that reduce power consumption and increase reliability.
