![]() ![]() Increased capacityĭDR4 supports higher-density chips and stacking technologies that may allow for single memory modules with capacities as high as 512GB. ![]() This is a great benefit for notebooks, as it provides longer battery life. Reduced power consumptionĭDR4 is more efficient that DDR3, consuming up to 40% less power and requiring only 1.2V per module. ![]() Planned speed increases could take it well beyond 3200MHz. Faster speedsĪs for technological differences, DDR4 has faster speeds, starting at 2133MHz, which would be high-end for DDR3. To improve strength and electrical contact, there is a slight curve in the shape of the bottom of the PCB. Instead of 240 pins, each module features 288 pins. The notch has been moved to prevent accidental insertion of the wrong type of memory. DDR4 RAM is not compatible with DDR3 motherboards, and vice versa. DDR4 modules don’t look different at first glance, but there are some subtle differences. ![]()
