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).

2.3 Installation of Memory Modules (DIMM)

is motherboard provides eight 288-pin DDR4 (Double Data Rate 4) DIMM slots, and
supports Quad Channel Memory Technology.

1. For quad channel cong uration, you always need to install identical (the same brand,
speed , size and chip-type) DDR4 DIMM pairs.

2. 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.

3. 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.

2.4 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 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 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.
PCIE3 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE4 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE5 (PCIe 3.0 x16 slot) is used for PCI Express x8 lane width graphics cards.
* If you install CPU with 44 lanes, PCIE1/PCIE2/PCIE3/PCIE5 will run at x16/x4/
x16/ x8.
* If you install CPU with 28 lanes, PCIE1/PCIE2/PCIE3/PCIE5 will run at x16/x4/
x8/x0.

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”. 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. 26)

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.

2.6 Onboard Headers and Connectors

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.

PWRBTN (Power Switch):

Connec t to the power switch on the chassi s front panel. You may congure the way to tur n

RESET (Reset Switch):
Connec t to the reset switch on the chassi s front panel. Press the reset sw itch 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
switch, reset switch , 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.

ere is one header on
this motherboard. is
USB 3.0 header can
support two ports.

is header is for
connecting audio devices
to the front audio panel.

1. High Denition Audio supports Jack Sensing, but the panel wire on the chassis must sup­port HDA to function correctly. Please follow the instructions in our manual and chassis
manual to install your system.

2. If you use an AC’97 audio panel , please install it to the front panel audio header by the
steps below:
A. Connect Mic_IN (MIC) to MIC2_ L.
B. Conne ct Audio_R (RIN) to OUT2_R and Audio_ L (LIN) to OUT2_ L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_ RET and OUT_RET are for the HD audio panel only. You don’t need to connect
them for the AC’97 audio panel .
E. To activate the front mic, go to the “FrontMic” Tab in the Realtek Control panel and
adjust “Recording Volume”.
