DDRII1 DDRII2 DDRII3 DDRII4
1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 memory sockets and supports Dual Channel Technology. After
the memory is installed, the BIOS will automatically detect the specifications and capacity of the
memory. Enabling Dual Channel memory mode will double the original memory bandwidth.
The four DDR2 memory sockets are divided into two channels and each channel has two memory
sockets as following:
Channel 0: DDRII1, DDRII2
Channel 1: DDRII3, DDRII4
Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same
colored DDR2 sockets for optimum performance.
When memory modules of different capacity and chips are installed, a message which says
memory is operating in Flex Memory Mode will appear during the POST. Intel®Flex Memory
Technology offers greater flexibility to upgrade by allowing different memory sizes to be
populated and remain in Dual Channel mode/performance.

the external SATA con-
nector on the bracket.
Then attach the SATA
power cable to the
power connector on
the bracket.
The SATA bracket allows you to connect external SATA device(s) to your system by expanding the
internal SATA port(s) to the chassis back panel.
•Turn off your system and the power switch on the power supply before installing or
removing the SATA bracket and SATA power cable to prevent damage to hardware.
•Insert the SATA signal cable and SATA power cable securely into the corresponding connec-
tors when installing.
Step 5:
Connect the other ends of the SATA signal cable and SATA power cable
to your SATA device. For SATA device in external enclosure, you only
need to connect the SATA signal cable. Before connecting the SATA signal
cable, make sure to turn off the power of the external enclosure.
