1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:

Make sure that the motherboard supports the memory. It is recommended that memory of

the same capacity, brand, speed, and chips be used.

(Go to GIGABYTE's website for the latest memory support list.)

Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage.

Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction.

1-4-1 Dual Channel Memory Configuration

This motherboard provides two DDR2 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth.

The two DDR2 memory sockets are divided into two channels and each channel has one memory socket as following:

Channel 0: DDRII1 Channel 1: DDRII2

DDRII1

DDRII2

Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.

1.Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.

2.When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used.
