DDR2 is the next-generation evolution of DDR memory technology. DDR2 memory features faster speeds, higher data bandwidths, lower power consumption, and enhanced thermal performance. DDR2 memory modules share the same module dimensions as DDR memory modules, but are not backward-compatible due to incompatible module connections (number of pins), voltage, and DRAM technology. DDR2 memory modules have a different key or notch than same-sized DDR modules to prevent their insertion into an incompatible memory socket.
