English Dual Channel DDR II Memory Configuration The GA-8I945GMBX 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-8I945GMBX includes 4 DIMM sockets, and each Channel has 2 DIMM sockets as following: Channel A : DDR II 1, DDR II 2 Channel B : DDR II 3, DDR II 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 II memory modules are installed. 2. If two DDR II 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 II memory modules are installed on the same channel. 3. If four DDR II 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 II memory modules. 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 is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side) 2 memory modules DDR II 1 DS/SS DDR II 2 X DDR II 3 DS/SS DDR II 4 X 4 memory modules X DS/SS DS/SS DS/SS X DS/SS DS/SS DS/SS - 15 - Hardware Installation
