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.

module is installed.

recommended to use memory modules of identical brand, size, chips,
and speed), you must install them into DIMM sockets of the same color.
