Chapter 1 Hardware Installation

1-1 Installation Precautions

The motherboard contains numerous delicate electronic circuits and components which can become

damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read the user's

manual and follow these procedures:

•Prior to installation, make sure the chassis is suitable for the motherboard.

•Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or

warranty sticker provided by your dealer. These stickers are required for warranty validation.

•Always remove the AC power by unplugging the power cord from the power outlet before

installing or removing the motherboard or other hardware components.

•When connecting hardware components to the internal connectors on the motherboard, make

sure they are connected tightly and securely.

•When handling the motherboard, avoid touching any metal leads or connectors.

•It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic

components such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,

keep your hands dry and rst touch a metal object to eliminate static electricity.

•Prior to installing the motherboard, please have it on top of an antistatic pad or within an

electrostatic shielding container.

•Before connecting or unplugging the power supply cable from the motherboard, make sure

the power supply has been turned off.

•Before turning on the power, make sure the power supply voltage has been set according to

the local voltage standard.

•Before using the product, please verify that all cables and power connectors of your hardware

components are connected.

•To prevent damage to the motherboard, do not allow screws to come in contact with the

motherboard circuit or its components.

•Make sure there are no leftover screws or metal components placed on the motherboard or

within the computer casing.

•Do not place the computer system on an uneven surface.

•Do not place the computer system in a high-temperature or wet environment.

•Turning on the computer power during the installation process can lead to damage to system

components as well as physical harm to the user.

•If you are uncertain about any installation steps or have a problem related to the use of the

product, please consult a certied computer technician.

•If you use an adapter, extension power cable, or power strip, ensure to consult with its installation

and/or grounding instructions.

1-3 Installing the CPU

Read the following guidelines before you begin to install the CPU:

•Make sure that the motherboard supports the CPU.

•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.

- 10 -

Installing the CPU

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

Due to CPU limitations, read the following guidelines before installing the memory in 6 Channel mode.

1. 6 Channel mode cannot be enabled if only one memory module is installed.

2. When enabling 6 Channel mode with two memory modules, it is recommended that memory of the same

capacity, brand, speed, and chips be used.

6ChannelMemoryConguration

This motherboard supports 6 Channel Technology. After the memory is installed, the BIOS will automatically

detect the specications and capacity of the memory.

The twelve DDR4 memory sockets are divided into 6 channels and each channel has two memory sockets

as following:

Channel 1: P1-DIMM-A1 (For CPU 1)/P2-DIMM-G1 (For CPU 2)

Channel 2: P1-DIMM-B1 (For CPU 1)/P2-DIMM-H1 (For CPU 2)

Channel 3: P1-DIMM-C1 (For CPU 1)/P2-DIMM-J1 (For CPU 2)

Channel 4: P1-DIMM-D1 (For CPU 1)/P2-DIMM-K1 (For CPU 2)

Channel 5: P1-DIMM-E1 (For CPU 1)/P2-DIMM-L1 (For CPU 2)

Channel 4: P1-DIMM-F1 (For CPU 1)/P2-DIMM-M1 (For CPU 2)

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.
