Safety information
Electrical safety
•
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
•
When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
•
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
•
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
•

Product introduction
1.1
Before you proceed
1
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.
Standby Power LED
The motherboard comes with a standby power LED that lights up to indicate that the system
is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down
the system and unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard LED.

Motherboard overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits.
Unplug the power cord before installing or removing the motherboard. Failure to do so can
cause you physical injury and damage to motherboard components.
1.2.1
Placement direction
When installing the motherboard, place it into the chassis in the correct orientation. The edge
with external ports goes to the rear part of the chassis as indicated in the image.
1.2.2
Screw holes
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side
towards the rear
of the chassis

•
Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
•
Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1150 socket.
•
The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.

Memory configurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM
sockets.
1-8
•
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 configuration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
•
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.
•
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:
-
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
-
Install a 64-bit Windows® OS if you want to install 4GB or more on the
motherboard.
-
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 megabits (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 efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
•

Expansion slots
In the future, you may need to install expansion cards. The following sub‑sections describe
the slots and the expansion cards that they support.
Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
1.5.1
Installing an expansion card
To install an expansion card:
1.
Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.
2.
Remove the system unit cover (if your motherboard is already installed in a chassis).
3.
Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.
4.
Align the card connector with the slot and press firmly until the card is completely
seated on the slot.
5.
Secure the card to the chassis with the screw you removed earlier.
6.
Replace the system cover.
1.5.2
Configuring an expansion card
After installing the expansion card, configure 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, conflicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.5.3
PCI slot
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specifications.
1.5.4

1.6Jumpers
Clear RTC RAM (3-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.

Normal
(Default)
Clear RTC
Z97-K Clear RTC RAM
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3
for about 5-10 seconds, then move the cap back to pins 1-2.
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 reenter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
1-12
•
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 the 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.
