DDR2 SDRAM is the next generation of high-density, high-bandwidth memory that provides ultra high-speeds at 50% lower power consumption to enhance the digital experience. DDR2 SDRAM achieves a data transfer rate of up to 533Mbps, double that of DDR266, and when used in a dual channel configuration has a memory bandwidth of up to 8.4GBps. DDR2 operates at 1.8V which lowers the internal system temperature, and uses smaller FBGA DRAMS enabling better electrical performance and speed. DDR2 provides module densities ranging from 256MB to 2GB.

DDR2 at 667MHz is known as PC2-5300, DDR2 at 533MHz is known as PC2-4300 & DDR2 at 400MHz is known as PC2-3200.
