Dual Channel DDR

GA-7N400S / GA-7N400S-L supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add double up to 6.4GB/s(DDR400) or 5.3GB/s(DDR333).

GA-7N400S / GA-7N400S-L includes 3 DIMM sockets as following:

Channel A : DDR 1, DDR 2

Channel B : DDR 3

If you want to operate the Dual Channel Technology, please note the following explanations due to the limitation of Intel chipset specifications.

1.Dual channel memory cannot be used if one DDR memory module is installed.

2.If two DDR memory modules are installed (same storage capacity), one must be added to the Channel A slot and the other in the Channel B slot in order to use dual channel memory. Dual channel memory cannot function if both DDR memory modules are installed on the same channel.

3.If three DDR memory modules are installed, please use memory of the same storage capacity in

order to use dual channel memory and for BIOS to detect all the DDR memory modules.

We'll strongly recommend our user to slot two DDR memory modules into the DIMMs with the same color in order for Dual Channel Technology to work.

The following table is for Dual Channel Technology combination: (DS: Double Side, SS: Single Side)

	DDR 1	DDR 2	DDR 3
2 memory module	DS/SS	X	DS/SS
	X	DS/SS	DS/SS
3 memory module	DS/SS	DS/SS	DS/SS
