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.

in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not over-

2.1 Installing the CPU

1. Before you insert the 2066-Pin CPU into the socket, plea se check if the PnP ca p is 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 installing 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guration, 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 DDR 3 memory modul e into a DDR4 slot;
otherwise, this motherboard and DIMM may be damaged.

3. e DIMM only ts in one correct orientation . It will cause per manent damage to the
motherboard and the DIMM if you force the DIM M 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 expansion card, please mak e 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 x8 lane width graphics cards.

PCIE3 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.

PCIE4 (PCIe 2.0 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/x8/

x16/x0 or x8/x8/x16/x8.

* If you install CPU with 28 lanes, PCIE1/PCIE2/PCIE3/PCIE5 will run at x16/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

(CLR MOS1)

(see p.7, No. 28)

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.

1. You should only use identical CrossFireXTM-ready graphics cards that are AMD certied.

2. Make sure that your graphics card driver supports AMD CrossFireXTM technology.
Download the dr ivers from the AMD’s website: www.amd.com

3. Make sure that your power supply unit (PSU) can provide at l east the minimum power
your system requires. It is recommended to use a A MD certied PSU. Please refer to the
AMD’s website for details.

4. If you pair a 12-pipe CrossFireXTM Edition card with a 16-pipe card , both cards will oper­ate as 12-pipe cards while in CrossFireXTM mode.

5. Dierent CrossFireXTM cards may require dierent methods to enable CrossFireXTM.
Please refer to AMD graphics card manuals for detailed installation guide.
