Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module.

Reverse the installation steps when you wish to remove the DIMM module.

Dual Channel DDR II

GA-8I955X Royal/Pro supports the Dual Channel Technology. After operat- ing the Dual Channel Technology, the bandwidth of Memory Bus will double.

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 or three DDR II memory modules are installed.

2.To enable Dual Channel mode with 2 or 4 memory modules, it is recommended to use memory modules of identical brand, size, chips, and speed.

We'll strongly recommend our user to slot two DDR II memory modules into the DIMMs of 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 II 1	DDR II 2	DDR II 3	DDR II 4
2 memory modules	DS/SS	X	DS/SS	X
	X	DS/SS	X	DS/SS
4 memory modules	DS/SS	DS/SS	DS/SS	DS/SS
