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, pl ease 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 c ables 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 chann el 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 sl ot;
otherwise , this motherboard and DIM M 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.

Due to Intel® CPU spec denition, please install the memory modules on DDR4_A1,

•

DDR4_B1, DDR4_C1 and DDR4_D1 for rst priority. If the four DDR4 DIMM slots

above are fully installed, and you want to use more than four memory modules, please

install the other memor y modules from le to right (from DDR4_A2, DDR4_B2,

DDR4_D2 to DDR4_C2.)

If only two memory modules are installed in the DDR4 DIMM slots, then Dual

Channel Memory Technology is activated. If three memory modules are installed, then

Triple Channel Memory Technology is activated. If more than four memory modules

are installed in the DDR4 DIMM slots, then Quad Channel Memory Technolog y is

activated.

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 x16 slot) is used for PCI Express x8 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 48 lanes, PCIE1/PCIE2/PCIE3/PCIE5 will run at x16/x8/

x16/x8.

* 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

“O pen”.

English

Clear CMOS Jumper

(CLRCMO S1)

(see p.8, No. 26)

CLRCMOS1 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 CLRCMOS1 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.

e Clear CMOS Button has the same function as the Cl ear CMOS jumper.
