Dual Channel Memory Configuration
The GA-965GM-DS2 / GA-965GM-S2 supports the Dual Channel Technology.
After operating the Dual Channel Technology, the bandwidth of memory bus
will double.
The GA-965GM-DS2 / GA-965GM-S2 includes 4 DIMM sockets, and each
Channel has two DIMM sockets as following:
Channel 0 : DDRII1, DDRII2
Channel 1 : DDRII3, DDRII4
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 DDRII 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,
X:Empty)
