1-4-1 Dual/3 Channel Memory Conguration
This motherboard provides four DDR3 memory sockets and supports Dual/3 Chan-
nel Technology. After the memory is installed, the BIOS will automatically detect the
specicationsandcapacityofthememory.Dualor3Channelmemorymodemay
double or triple the original memory bandwidth.
The four DDR3 memory sockets are divided into three channels:
Channel 0: DDR3_1
Channel 1: DDR3_4
Channel 2: DDR3_2, DDR3_3

Due to chipset limitations, read the following guidelines before installing the memory in Dual or 3 Channel mode.
Dual Channel--
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two modules, it is recommended that memory of the same ca-
pacity, brand, speed, and chips be used. When enabling Dual Channel mode with two memory modules,
be sure to install them in the DDR3_1 and DDR3_4 or DDR3_1 and DDR3_2 sockets.
3 Channel--
1. 3 Channel mode cannot be enabled if only one or two DDR3 memory modules are installed.
2. When enabling 3 Channel mode with three or four modules, it is recommended that memory of the same
capacity, brand, speed, and chips be used. When enabling 3 Channel mode with three memory modules,
be sure to install them in the DDR3_1, DDR3_2 and DDR3_4 sockets.
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.
(Go to GIGABYTE's website for the latest memory support list.)
• Always turn off the computer and 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.
• For the DDR3_2/DDR3_3 memory socket, make sure the memory module to be installed is a
SA2 memory module.
• If only one DDR3 memory module is installed, it is recommended to install it in the DDR3_1 socket.
• 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 Tech-
