1-3 Installing the CPU

Always turn off the computer and unplug the power cord before installing the CPU to prevent hardware damage. Do not turn on the computer if the CPU cooler is not installed, as this will cause overheating and damage.

Before installation, ensure the motherboard supports the CPU (check GIGABYTE's website for the latest CPU support list). Locate pin one (marked by a small triangle) on both the CPU socket and the CPU. The CPU can only be inserted in one orientation. Apply a thin, even layer of thermal grease to the CPU surface.

Set the CPU host frequency according to specifications. Setting it beyond hardware specifications is not recommended as it may not meet peripheral requirements.

1-4 Installing the Memory

Always turn off the computer and unplug the power cord before installing memory to prevent hardware damage.

Ensure the motherboard supports the memory. It is recommended to use memory modules of the same capacity, brand, speed, and chips (check GIGABYTE's website for supported memory speeds and modules). Memory modules have a foolproof design and can only be installed in one direction. If insertion is difficult, switch the direction.

Dual Channel Memory Configuration

This motherboard has two memory sockets supporting Dual Channel Technology. The BIOS automatically detects memory specifications and capacity after installation. Enabling Dual Channel mode doubles memory bandwidth. The sockets are divided into two channels:

• Channel A: DDR4_A1
• Channel B: DDR4_B1

Dual Channel mode requires at least two memory modules. For optimal performance with two modules, use memory of the same capacity, brand, speed, and chips.
