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 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.
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.
• Each channel can only t one memory module when using DDR3 2200 MHz memory module.
• 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 exibility to upgrade by allowing different memory sizes to be popu
lated and remain in Dual Channel mode/performance.
1-4-1 Dual Channel Memory Conguration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specications 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 0: DDR3_1, DDR2_2
Channel 1: DDR3_3, DDR3_4
DDR3_1 DDR3_2
DDR3_3
DDR3_4

1-4-2 Installing a Memory
Notch
Before installing a memory module, make sure to turn off the computer and unplug the power
cord from the power outlet to prevent damage to the memory module.
DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install
DDR3 DIMMs on this motherboard.
DDR3 DIMM
A DDR3 memory module has a notch, so it can only t in one direction. Follow the steps below to correctly
install your memory modules in the memory sockets.
Step 1:
Note the orientation of the memory module. Spread the retaining
clips at both ends of the memory socket. Place the memory module
on the socket. As indicated in the picture on the left, place your n-
gers on the top edge of the memory, push down on the memory and
insert it vertically into the memory socket.
Step 2:
The clips at both ends of the socket will snap into place when the
memory module is securely inserted.
