DDR4 is expected exceed 3GHz, uses up to 40% less power than DDR3, and may support up to 256GB on a single module. It is expected to increase performance by 50% compared to DDR3. Improved data reliability features include cyclic redundancy checks (CRC), on-chip parity detection, enhanced signal integrity, and additional RAS features. DDR4 is the latest iteration of synchronous DRAM.
Physically, DDR4 has 288 pins vs the 240 on DDR3. To prevent accidental installation into a DDR3 motherboard, the module key is located in a different position. The curve in the center of the DIMM adds module insertion strength and improves electrical connectivity.
