1-4 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.
(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
direction. If you are unable to insert the memory, switch the direction.
1-4-1 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. 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 0: DDRIII1, DDRIII2
Channel 1: DDRIII3, DDRIII4

• Each channel can only fit one memory module when using DDR3 1900/1600 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 flexibility to upgrade by allowing different memory sizes
to be populated and remain in Dual Channel mode/performance.
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.
