Dual Channel Memory Configuration

The GA-G1975X supports the Dual Channel Technology. After operating the

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

GA-G1975X 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.Dual Channel mode will not be enabled if only one DDR II memory module is installed.

2.To enable Dual Channel mode with two or four memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed), you must install them into DIMM sockets of the same color.

The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side)
