Chapter 2 Installation

is is an ATX form factor motherboard. Before you install the motherboard, study

the conguration of your chassis to ensure that the motherboard ts into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

• Make sure to unplug the power cord before installing or removing the motherboard

components. Failure to do so may cause physical injuries and damages to motherboard

components.

• In order to avoid damage from static electricity to the motherboard’s components,

NEVER place your motherboard directly on a carpet. Also remember to use a grounded

wrist strap or touch a safety grounded object before you handle the components.

• Hold components by the edges and do not touch the ICs.

• Whenever you uninstall any components, place them on a grounded anti-static pad or

2.1 Installing the CPU

1. Before you insert the 1151-Pin CPU into the socket , please check if the PnP c ap is on the socket, if the CPU sur face is unclean, or if th ere are any b ent pins in the socket. Do not force to insert the CPU into the socket if above situ ation is found. Other wise, the CPU wil l be seriously d amaged.

2. Unplug all power cables be fore installing the CPU.

2.3 Installing Memory Modules (DIMM)

is motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identica l (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Dual Channel Memor y Technology with only one or three memor y module installed.

3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot; otherwise, this motherboard and DIMM may be damaged.

Before installing an ex pansion card, please make sure that the power supply is switched o or the power cord is unplugged. Plea se read the documentation of the expan sion card and mak e necessary hardware settings for the card before you start the installation.

PCIe slots:

PCIE1 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.

PCIE3 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

2.5 Jumpers Setup

e illustration shows how jumpers are setup. When the jumper cap is placed on

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is

“Open”.

Clear CMOS Jumper

(CLRMOS1)

(see p.8, No. 23)

CLRMOS1 allows you to clear the data in CMOS. e data in CMOS includes

system setup information such as system password, date, time, and system setup

parameters. To clear and reset the system parameters to default setup, please turn

o the computer and unplug the power cord, then use a jumper cap to short the

pins on CLR MOS1 for 3 seconds. Please remember to remove the jumper cap aer

clearing the CMOS. If you need to clear the CMOS when you just nish updating

the BIOS, you must boot up the system rst, and then shut it down before you do

the clear-CMOS action.

e Clear CMOS Button has the same function as the Cl ear CMOS jumper.

Secure Backup UEFI

Whenever one of the ROM images are outdated or corrupted, switch to the other ash

ROM and execute Secure Backup UEFI to duplicate the current working ROM image to

the secondary ash ROM..

is motherboard has two BIOS chips, an active BIOS (BIOS_ A) and a backup BIOS (BIOS_ B), which enhances the safety and stability of your system. Use “Secure Backup UEFI” to duplicate a working copy of the BIOS les to the active BIOS to ensure normal system operation. Normally, the system will work on the active BIOS. However if the active BIOS is corrupted or damaged , aer se veral failed boot attempts, the backup BIOS will take over. For safety issues , users are not abl e to update the backup BIOS manually. Users may refer to the BIOS LEDs (BIOS_ A_LED or BIOS_ B_LED) to identify which BIOS is currently activated.
