Installing the CPU |
|
|
||
|
Read the following guidelines before you begin to install the CPU: |
|
|||
|
•• |
Make sure that the motherboard supports 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 |
|

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.
Dual Channel Memory Configuration
This motherboard provides four 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 memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR4_2, DDR4_4Channel B: DDR4_1, DDR4_3
Please visit GIGABYTE's website |
Please visit the Support\Utility List |
for support lists of CPU, memory |
page on GIGABYTE's website to |
modules, SSDs, M.2, and U.2 devices. |

1/2) ATX_12V/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
Withtheuseofthepowerconnector,thepowersupplycansupplyenoughstablepowertoallthecomponents on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.
