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.

 

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 pin one (denoted by a small triangle) of the CPU socket and the CPU.

1-4  Installing the Memory

Dual Channel Memory Configuration

This motherboard provides two 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 DDR4 memory sockets are divided into two channels and each channel has one memory socket as 

following:

 

Channel A: DDR4_2

 

Channel B: DDR4_1

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.

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 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.

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