Chapter 2 Installation

is is a Micro 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

•

in the bag that comes with the components. When placing screws to secure the motherboard to the chassis, please do not over-

•

tighten the screws! Doing so may damage the motherboard.

English

2.1 Installing the CPU

1. Before you insert the 1200-Pin CPU into the socket, please check if the PnP cap is on the socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to in sert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.

2. Unplug all power cables before in stalling 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 identical (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

memory 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.

2.4 Expansion Slots (PCI Express Slots)

ere are 3 PCI Express slots on the motherboard.

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 make necessary hardware settings for the card before you start the installation.

PCIe slots:

PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards. PCIE2 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards. PCIE3 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics 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 (CLRMO S1) (see p.1, No. 22)

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to default setup, please turn o the computer and unplug the power cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to short the pins on CLRMOS1 for 5 seconds. However, please do not clear the CMOS right aer you update the BIOS. 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. Please be noted that the password, date, time, and user default prole will be cleared only if the CMOS battery is removed. Please remember toremove the jumper cap aer clearing the CMOS.

2-pin Jumper

English

If you clear the CMOS, the case open may be detec ted. Please adjust the BIOS option “Clear Status” to clear the record of previou s chassis intrusion status.

2.6 Onboard Headers and Connectors

SPEAKER

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard.

is connector supports SPI Trusted Platform Module (TPM) system, which can securely store keys, digital certicates, passwords, and data. A TPM system also helps enhance network security, protects digital identities, and ensures platform integrity.

Please connect a underbolt™ add-in card (AIC) to this connector via the GPIO cable. *Please install the underbolt™ AIC card to PCIE3 (default slot).

2.7 M.2 WiFi/BT Module Installation Guide

e M.2, also known as the Next Generation Form Factor (NGFF), is a small size and versatile card edge connector that aims to replace mPCIe and mSATA. e M.2 Socket (Key E) supports type 2230 WiFi/BT module. * e M.2 socket does not support SATA M.2 SSDs.

Installing the WiFi/BT module

Step 1

Prepare a type 2230 WiFi/BT module and the screw.

Step 2

Find the nut location to be used.

PCB Length: 3cm Module Type: Type2230

2.8 M.2_SSD (NGFF) Module Installation Guide (M2_1)

e M.2, also known as the Next Generation Form Factor (NGFF), is a small size and versatile card edge connector that aims to replace mPCIe and mSATA. e Ultra M.2 Socket (M2_1) supports M Key type 2242/2260/2280 M.2 PCI Express module up to Gen3 x4 (32 Gb/s).

Installing the M.2_SSD (NGFF) Module

Step 1

Prepare a M.2_SSD (NGFF) module and the screw.

English

Step 2

Before installing a M.2 (NGFF) SSD module, please loosen the screws to remove the M.2 heatsink. *Please remove the protective lms on the bottom side of the M.2 heatsink before you install a M.2 SSD module.

Step 3

Depending on the PCB type and length of your M.2_SSD (NGFF) module, nd the corresponding nut location to be used.
