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.

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g uration , you always need to in stall identical (the same b rand,

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

2. It i s unable to activate Dual Channel Memory Technology with only one or three memory
module installed.

3. It i s not allowed to in stall a DDR , DDR2 or DDR3 memor y module into a DDR4 slot;
otherwise , this motherboard and DIM M may be damaged.

e DIMM only ts in one correct orie ntation. It will cause permanent dam age to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

2.4 Expansion Slots (PCI Express Slots)

ere are 5 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 unplug ged. Pl ease re ad the documentation of the expansion 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.

PCIE4 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE5 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

2.6 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

“O pen”.

Clear CMOS Jumper

(CLRMO S1)

(see p.8, No. 31)

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.

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

PWRBTN (Power Button):

Connec t to the power button on the ch assi s front panel. You may congure the way to tur n

RESET (Reset B utton):
Connec t to the reset button on the ch assi s front panel. P ress the reset button to re start the
computer if the computer f reezes and fails to per form a normal restar t.

PLED (Syste m Power LED):
Connec t to the power status indicator on the chas sis front panel. e LED i s on when the
system is operating. e LED keeps blinking when the system is in S1/S3 sleep state. e
LED is o when the system is in S4 slee p state or powered o (S5).

HDLED (Ha rd Drive Activity LED):
Connec t to the hard drive ac tivity LED on the chassis front panel. e LED is on when the
hard drive is reading or wr iting data.

e front panel de sign may dier by chassis. A front panel module mainly consists of powe r
button, reset button , power LED, hard dr ive activity LED, speaker and etc. When connect­ing your ch assi s front panel module to thi s header, make sure the wire a ssignments and the
pin assignments are matched correctly.
