1.7.1 Overview

The motherboard comes with two 240-pin Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin
footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to
prevent installation on a DDR DIMM socket. The following figure illustrates the location of
the sockets:
