Intel GA-8I915G-MFD user manual Dual Channel DDR

Dual Channel DDR II

GA-8I915G-MFD supports the Dual Channel Technology. After operating the

Dual Channel Technology, the bandwidth of Memory Bus will double.

GA-8I915G-MFD includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel A : DDR II 1, DDR II 2

Channel B : DDR II 3, DDR II 4

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

1.One/three DDR II memory module is installed: The Dual Channel Technology can't operate when only one DDR II memory module is installed.

2.Two DDR II memory modules are installed (the same memory size and type): The Dual Channel Technology will operate when two memory modules are inserted individually into Channel A and B. If you install two memory modules in the same channel, the Dual Channel Technology will not operate.

3.Four DDR II memory modules are installed: If you install four memory modules at the same time, the Dual Channel Technology will operate only when those modules have the same memory size and type.

We'll strongly recommend our user to slot two DDR II 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 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
