1.4.1 Overview
This motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Module
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption. The gure illustrates the
location of the DDR3 DIMM sockets:
