1.7.1Overview

The motherboard comes with two 240-pin Double Data Rate (DDR2) and two 184-pin DDR Dual Inline Memory Modules (DIMM) sockets.

DDR2 DIMMS are notched differently to prevent installation on a DDR DIMM socket.

The following figure illustrates the location of the sockets:

Color	Sockets
Blue	DDR_1 and DDR_2
Yellow	DDR2_1 and DDR2_2
	DDR2 1 DDR2 2	DDR 1	DDR 2

P5VDC-MX DDR DIMM sockets

•To prevent damage to the motherboard, do not use DDR and

DDR2 memory simultaneously.

•Due to chipset resource allocation, the system may detect less than 2 GB system memory when you installed two 1 GB DDR2 or DDR memory modules.

1.7.2Memory Configurations

You may install 256MB, 512MB, and 1 GB unbuffered non-ECC DDR/DDR2 DIMMs into the DIMM sockets.
