Gigabyte GA-8N775 User Manual page 15

GA-8N775 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)
