512MB PC2-5300S 667MHz DDR2 SDRAM Laptop Memory DDR2 memory
modules have basically the same dimensions as the DDR modules, but
because of different voltages and pin configurations, DDR2 modules
have a different "key" or notch in their connector to prevent them
from being plugged into an incompatible socket. DDR2 memory modules
will only fit in systems and motherboards designed to specifically
support DDR2 memory. A DDR2 SODIMM will not fit in the DDR memory
slot.
DDR2 modules use a 1.8 V power supply, providing a big power saving
over the 2.5 V DDR modules. DDR2 modules for notebook computers
require up to 65% less voltage than DDR, thus improving battery
life. The extended battery life can improve mobility and
productivity.
