2.4.1 Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but is notched
differently to prevent installation on a DDR DIMM socket. DDR2 modules are
developed for better performance with less power consumption.
The figure illustrates the location of the DDR2 DIMM sockets:
