DDR3 Modules can transfer data at a rate of 800--1600 MHz using both rising and falling edges of a 400--800 MHz I/O clock. In comparison, DDR2's current range of data transfer rates is 400--800 MHz using a 200--400 MHz I/O clock, and DDR's range is 200--400 MHz based on a 100--200 MHz I/O clock. DDR3 Modules have 240 pins, the same number as DDR2, and are the same size, but are electrically incompatible and have a different key notch location to avoid usage of wrong type of RAM with incompatible slots.
