Dual Channel Memory Configuration
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.
