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.

English
Z170 Pro4
2.1 Installing the CPU
1. Before you insert the 1151-Pin CPU into the socket, please check if the PnP cap
is on the socket, if the CPU surface is unclean, or if there are any bent pins in the
socket. Do not force to insert 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.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
Dual Channel Memory Conguration
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.

1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory 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.

2.4 Expansion Slots (PCI Express Slots)
ere are 5 PCI Express slots on the motherboard.
PCIe slots:
PCIE1 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE3 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.
PCIE5 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIe Slot Congurations
For a better thermal environment, please connect a chassis fan to the motherboard’s
chassis fan connector (CHA_FAN1, CHA_FAN2 or CHA_FAN3) when using mul-
tiple graphics cards.
Before installing an expansion 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.

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
(CLRMOS1)
(see p.1, No. 25)
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.
Clear CMOSDefault
If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
“Clear Status” to clear the record of previous chassis intrusion status.
