DualChannelMemoryConguration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memoryisinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.Enabling
Dual Channel memory mode will double the original memory bandwidth.
The four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as
following:
Channel A: DDR3_1, DDR3_3
Channel B: DDR3_2, DDR3_4
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 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 DDR3
sockets. For optimum performance, when enabling Dual Channel mode with two memory modules,
we recommend that you install them in the DDR3_1 and DDR3_2 sockets.
1-5 Installing an Expansion Card

•Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
•Always turn off the computer and unplug the power cord from the power outlet before installing an
expansion card to prevent hardware damage.
