Chapter 2 Installation
This is a Micro ATX form factor motherboard. Before you install the
motherboard, study the configuration of your chassis to ensure that the
motherboard fits 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
overtighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1700-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 insert the CPU into the socket if
above situation is found. Otherwise, the CPU will be seriously damaged.
2. Unplug all power cables before installing the CPU.

2.3 Installing Memory Modules (DIMM)
This motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel configuration, 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 Memory 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.
4. The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into the slot at
incorrect orientation.

Expansion Slots (PCIe Slots)
There are 3 PCI Express slots on the motherboard.
Before installing an expansion card, please make sure that the power supply is
switched off or the power cord is unplugged. Please read the documentation of
the expansion card and make necessary hardware settings for the card before
you start the installation.
PCIe slots: PCIE1 (PCIe 4.0 x16 slot) is used for PCIe x16 lane width graphics
cards. PCIE2 (PCIe 3.0 x1 slot) is used for PCIe x1 lane width cards. PCIE3
(PCIe 3.0 x16 slot) is used for PCIe x4 lane width graphics cards.

2.11 Jumpers Setup
The 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.6, No. 21) CLRMOS1 allows you to clear the
data in CMOS. The 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 off the computer and
unplug the power cord, then use a jumper cap to short the pins on CLRMOS1 for
3 seconds. Please remember to remove the jumper cap after clearing the CMOS.
If you need to clear the CMOS when you just finish updating the BIOS, you must
boot up the system first, and then shut it down before you do the clear-CMOS
action.

2.12 Onboard Headers and Connectors
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.
System Panel Header (9-pin PANEL1) (see p.6, No. 15) Connect the power button,
reset button and system status indicator on the chassis to this header
according to the pin assignments below. Note the positive and negative pins
before connecting the cables.

PWRBTN (Power Button): Connect to the power button on the chassis front panel.
You may configure the way to turn off your system using the power button.
RESET (Reset Button): Connect to the reset button on the chassis front panel.
Press the reset button to restart the computer if the computer freezes and
fails to perform a normal restart. PLED (System Power LED): Connect to the
power status indicator on the chassis front panel. The LED is on when the
system is operating. The LED keeps blinking when the system is in S1/S3 sleep
state. The LED is off when the system is in S4 sleep state or powered off
(S5). HDLED (Hard Drive Activity LED): Connect to the hard drive activity LED
on the chassis front panel. The LED is on when the hard drive is reading or
writing data. The front panel design may differ by chassis. A front panel
module mainly consists of power button, reset button, power LED, hard drive
activity LED, speaker and etc. When connecting your chassis front panel module
to this header, make sure the wire assignments and the pin assignments are
matched correctly.
