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 sock et. 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.

2.4 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 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 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/

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

(CLRMO S1)

(see p.7, 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.
