Answer Description

DDR4 is the correct choice because it is known for higher speed and efficiency advancements over earlier RAM types like DDR2 and DDR3. DDR4 operates at a lower voltage of 1.2V against DDR3's 1.5V and DDR2's 1.8V, resulting in less power consumption. It also supports larger module capacities which allow for greater RAM density in computer systems.
