Dual Channel DDR Memory Configuration

The GA-8I915PM-FS supports the Dual Channel Technology. When the Dual Channel Technology is activated, the bandwidth of memory bus will be double the original one.

The GA-8I915PM-FS includes 4 DIMM sockets, and each Channel has 2 DIMM sockets as following:

Channel A : DDR 1, DDR 2

Channel B : DDR 3, DDR 4

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 memory cannot be used if one or three DDR memory modules are installed.

2. If two DDR memory modules are installed (same storage capacity), one must be added to the Channel A slot and the other in the Channel B slot in order to use dual channel memory. Dual channel memory cannot function if both DDR memory modules are installed on the same channel.

3. If four DDR memory modules are installed, please use memory of the same storage capacity in order to use dual channel memory and for BIOS to detect all the DDR memory modules.

We'll strongly recommend our user to slot two DDR memory modules into the DIMMs with the same color in order for Dual Channel Technology to work.
