Dual Channel DDR/DDR II
The GA-8I915P Dual Graphic supports the Dual Channel Technology. When the Dual Channel Technology
is activated, the bandwidth of memory bus will be double the original one.
Due to chipset limitation, if you want to operate the Dual Channel Technology, please follow the guidelines
below for Dual Channel memory configuration.
1. Dual Channel mode will not be enabled if only one DDR/DDR II memory module is installed.
2. To enable Dual Channel mode with 2 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)
DDR 1
2 memory modules DS/SS
OR
DDR II 1
2 memory modules DS/SS
Note: Mixed mode, populating DDR and DDR II memory modules simultaneously is not supported.
