Dual Channel Memory Configuration
GA-8I945PL-G supports the Dual Channel Technology. After operating the
Dual Channel Technology, the bandwidth of Memory Bus will add double.
GA-8I945PL-G 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)
