Overview

The motherboard comes with two 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 figure illustrates the location of the DDR2 DIMM sockets:

• Always install DIMMs with the same CAS latency. For optimum compatibility,

it is recommended that you obtain memory modules from the same vendor.

• When installing total memory of 4GB capacity or more, Windows 32-bit

operation system may only recognize less than 3GB. Hence, a total

installed memory of less than 3GB is recommended.
