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)

The DIMM socket has a notch, so the DIMM memory module

Close the plastic clip at both edges of the DIMM sockets to
lock the DIMM module.
Reverse the installation steps when you wish to remove the
