Installing the CPU

Read the following guidelines before you begin to install the CPU:
• Make sure that the motherboard supports the CPU.
(Go to GIGABYTE's website for the latest CPU support list.)
• Always turn off the computer and unplug the power cord from the power outlet before installing the
CPU to prevent hardware damage.
• Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
• Apply an even and thin layer of thermal grease on the surface of the CPU.
• Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage
of the CPU may occur.
• Set the CPU host frequency in accordance with the CPU specifications. It is not recommended
that the system bus frequency be set beyond hardware specifications since it does not meet the
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specifications, please do so according to your hardware specifications including the CPU, graphics
card, memory, hard drive, etc.
Installing the CPU
Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.

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 two 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 two DDR3 memory sockets are divided into two channels and each channel has one memory socket as
following:
Channel A: DDR3_1
Channel B: DDR3_2
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 memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used for optimum performance.
