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.

Chapter 1: Product introduction
1.3.1 Installing the CPU
• Ensure that you install the correct CPU designed for LGA1150 only. DO NOT install a
CPU designed for LGA1155 and LGA1156 sockets on the LGA1150 socket.
• 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.
Ensure that you install the correct CPU designed for LGA1150 socket only. DO NOT install
a CPU designed for LGA1555 and LGA1156 sockets on the LGA1150 socket.

1.4 System memory
1.4.1 Overview
The motherboard comes with four Double Data Rate 3 (DDR3) Dual In-line Memory Modules
(DIMM) slots.
A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR
or DDR2 memory module to the DDR3 slot.
Install one memory module in slot A2 rst as a single-channel operation.
Recommended memory congurations

1-9
Chapter 1: Product introduction
1.4.2 Memory congurations
You may install 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the DIMM
sockets.
• 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) or overclocking condition.
• 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.
• 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 optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• 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 4GB 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 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

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 rmly 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 Conguring an expansion card
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. Install the software drivers for the expansion card.

Chapter 1: Product introduction
Ensure to save your data before using the DirectKey button.
DirectKey button
This feature allows your system to go to the BIOS Setup program with the press of a button.
With DirectKey, you can enter the BIOS anytime without having to press the <Delete> key
during POST. It also allows you to turn on or turn off your system and conveniently enter the
BIOS during boot-up.
• When the system is on and you press the DirectKey button, your system will shut
down. Press the DirectKey button again or the Power-on button to reboot and enter
the BIOS directly.
• Turn off your system using the power-on button to allow your system to go through
POST (without entering the BIOS) when you reboot your system.
• Refer to section 2.8 Boot Menu for details about setting the DirectKey default
function.
1.6 Onboard buttons
Onboard switches allow you to ne-tune performance when working on a bare or open-
case system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.

1. Standby power LED (SB_PWR)
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.
1.7 Onboard LEDs
2. POST State LEDs
The POST State LEDs provide the status of these key components during POST
(Power-On-Self Test): CPU, memory modules, VGA card, and hard disk drives. If an
error is found, the critical component’s LED stays lit up until the problem is solved.

Chapter 1: Product introduction
1.8 Jumpers
Clear RTC RAM jumper (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.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
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 <Delete> key during the boot process and enter BIOS setup to re-enter
data.
• If the steps above do not help, remove the onboard battery and move the jumper
again to clear the CMOS RTC RAM data. After the CMOS clearance, 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 C.P.R. (CPU Parameter Recall) feature.
Shut down and reboot the system so the BIOS can automatically reset parameter
settings to default values.
• Due to the 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.
