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 supported memory speeds and memory modules.)
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.
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: DDR3_2, DDR3_4

Channel 1: DDR3_1, DDR3_3

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. 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.

Read the following guidelines before you begin to install 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.
