DualChannelMemoryConguration

This motherboard provides four 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. Enabling Dual

Channel memory mode will double the original memory bandwidth.

Please visit GIGABYTE's website for details on hardware installation.

1-3 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 specications. It is not recommended

that the system bus frequency be set beyond hardware specications since it does not meet the

standard requirements for the peripherals. If you wish to set the frequency beyond the standard

specications, please do so according to your hardware specications including the CPU, graphics

card, memory, hard drive, etc.

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 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.

Installing the CPU

Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.

Do not remove the CPU socket cover before inserting the CPU. It may pop off from the load

plate automatically during the process of re-engaging the lever after you insert the CPU.
