1.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
1.2.2 Screw holes

The motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Modules
(DIMM) slots.
A DDR4 module is notched differently from a DDR, DDR2, or DDR3 module. DO NOT
install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
ASUS Z170-A Series 1-9
1.4.2 Memorycongurations
You may install 1 GB, 2 GB, 4 GB, 8GB, and 16 GB unbuffered non-ECC DDR4 DIMMs into
the DIMM sockets. You can refer to the recommended memory population below.
• You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
• Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
b) Install a 64-bit Windows® OS when you want to install 4 GB or more on the
motherboard.
c) For more details, refer to the Microsoft® support site at http://support.microsoft.
com/kb/929605/en-us.
• This motherboard does not support DIMMs made up of 512 Mb (64 MB) chips or less.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value. To operate at the vendor-marked
or at a higher frequency, refer to section 2.5 Ai Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs).
• Visit the ASUS website at: www.asus.com for the latest QVL.

Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
ASUS Z170-A Series 1-17
1.5.2 Conguringanexpansioncard
After installing the expansion card, congure it by adjusting the software settings:
1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
2. Assign an IRQ to the card.
3. Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts arise between the two PCI
groups, making the system unstable and the card inoperable.

1.6 Jumpers
1. Clear RTC RAM (2-pin CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing the
CMOS RTC RAM data. The onboard button cell battery powers the RAM data in
CMOS, which include system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-
enter data.
Except when clearing the RTC RAM, never short-circuit the CLRTC jumper. Shorting the
CLRTC jumper will cause system boot failure!
• If the steps above do not help, remove the onboard battery and move the jumper
again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the
battery.
• You do not need to clear the RTC when thae system hangs due to overclocking. For
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature.
Shut down and reboot the system, then the BIOS automatically resets parameter
settings to default values.
• Due to chipset behavior, AC power off is required to enable C.P.R. function. You must
turn off and on the power supply or unplug and plug the power cord before rebooting
the system.
1-20 Chapter 1: Product Introduction
2. CPU Over Voltage jumper (3-pin CPU_OV)
The CPU Over Voltage jumper allows you to set a higher CPU voltage for a exible
overclocking system, depending on the type of the installed CPU. To gain more CPU
voltage setting, insert the jumper to pins 2-3. To go back to its default CPU voltage
setting, insert the jumper to pins 1-2.
