1.7.1 Overview
The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(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 figure illustrates the location of the DDR3 DIMM sockets:
