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

•

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.

2.1 Installing the CPU

1. Before you insert the 2066-Pin CPU into the socket, please check if the PnP cap i s 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.

CAU TION:

Please note that X299 platform is only compatible with the LGA 2066 socket, which is
incompatible with the LGA 2011-3 socket (for X99 platform).

2.4 Installation of Memory Modules (DIMM)

B1

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 in stall 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.

4. e DIMM only ts 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.

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 “Open”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”

when a jumper cap is placed on these 2 pins.

Clear CMOS Jumper
(C LR MOS 1)
(see p.1, No. 39)

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 pin2 and pin3 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.

BIOS B Select Jumper
(F_BIOS_B1)
(see p.1, No. 32)

is motherboard has two BIOS chips, a primary BIOS (BIOS_A1) and a backup BIOS
(BIOS_B1), which enhances the safety and stability of your system. Normally, the system
will work on the primary BIOS. However, if the primary BIOS is corrupted or damaged,
use a jumper cap to short the pins, then the backup BIOS will take over on the next
system boot.

Short: Boot from BIOS B
Open: Default

2.7 Onboard Headers and Connectors

1

Onboard headers and connectors are NOT jumpers. 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.

System Panel Header
(9-pi n PANEL1)
(see p.1, No. 29)

PWRBTN (Power Button):

Connec t to the power button on the chassi s front panel. You may congure the way to tur n
o your system using the power button.

RESET (Reset B utton):
Connec t to the reset button on the chassi s front panel. Press the reset button to restart 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 chassis 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 activity LED on the chassis front panel. e LED is on when the
hard drive is reading or wr iting data.

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