DDR2

Short for double data rate two, DDR2 is the second generation of DDR (double data rate) memory released in September 2003. DDR2 can operate at greater speeds than DDR, offers a greater bandwidth potential, operates on less power, and generates less heat. Due to architectural differences, DDR2 memory modules are incompatible with DDR slots.
