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.
Ensure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.
If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
Operation safety
Before installing the motherboard and adding components, carefully read all the manuals that came with the package.
Before using the product, ensure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately.

Product introduction

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 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to ensure that the motherboard ts.
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 eight 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.

Unplug all power cables before installing the CPU.
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.

1.4 System memory

1.4.1 Overview
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module (DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption. The gure illustrates the
location of the DDR3 DIMM sockets:
Channel Sockets
Channel A DIMM_A1 & DIMM_A2
Channel B DIMM_B1 & DIMM_B2
VANGUARD B85 240-pin DDR3 DIMM sockets
DIMM_A1
DIMM_A2
DIMM_B1
DIMM_B2
1.4.2 Memory congurations
You may install 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets.
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 conguration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
Due to Intel
®
chipset limitation, DDR3 1600MHz and higher memory modules on XMP
mode will run at the maximum transfer rate of DDR3 1600MHz.
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.
This motherboard does not support DIMMs made up of 512 megabits (Mb) chips or less.
Memory modules with memory frequency higher than 2133 MHz and its corresponding timing or the loaded X.M.P. Prole is not the JEDEC memory standard. The stability and compatibility of these memory modules depend on the CPU’s capabilities and
other installed devices.
The maximum 32GB memory capacity can be supported with 8GB or above DIMMs. ASUS will update the memory QVL once the DIMMs are available in the market.
1-8
Chapter 1: Product introduction
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 efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

1.4.3 Installing a DIMM
Unplug the power supply before adding or removing DIMMs or other system components. Failure to do so can cause severe damage to both the motherboard and the components.
1. Press the retaining clips outward to unlock a DIMM socket.
2. Align a DIMM on the socket such that the notch on the DIMM matches the DIMM slot key on the socket.
A DIMM is keyed with a notch so that it ts in only one direction. DO NOT force a DIMM into
a socket in the wrong direction to avoid damaging the DIMM.
3. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.
1.4.4 Removing a DIMM
To remove a DIMM:
1. Simultaneously press the retaining clips outward to unlock the DIMM.

Support the DIMM lightly with
your ngers when pressing the
retaining clips. The DIMM might
get damaged when it ips out
with extra force.

1.6 Jumpers

1. 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.
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 re-
enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap 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 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.
