Installing the Memory

Read the following guidelines before you begin to install the memory:
• Make sure that the motherboard supports the memory. It is recommended that memory of the
same capacity, brand, speed, and chips be used.•
unplug the power cord from the power outlet before installing the memory to prevent hardware
damage.
• Memory modules have a foolproof design. A memory module can be installed in only one direc-
tion. If you are unable to insert the memory, switch the direction.
2-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. En-
abling 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: DDR_P0C0D0, DDR_P1C0D0
Channel B: DDR_P0C1D0, DDR_P1C1D0
Channel C: DDR_P0C2D0, DDR_P1C2D0

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 for optimum performance.
