Intel GA-8I915G DUO user manual Dual Channel DDR/DDR

Dual Channel DDR/DDR II

GA-8I915G Duo supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add double up to 6.4GB/s(DDR) ; 8.5GB(DDRII)

GA-8I915G Duo includes 4	DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR 1	or	Channel A : DDR II 1
Channel B : DDR 2		Channel B : DDR II 2

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

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

2.Two DDR/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.

We'll strongly recommend our user to slot two DDR/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 1	DDR 2
2 memory modules	DS/SS	DS/SS
OR
	DDR II 1	DDR II 2
2 memory modules	DS/SS	DS/SS

Note:Mixed mode, populating DDR and DDR II memory modules simultaneously is not supported.
