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.
Recommended memory congurations
Install one memory module in slot A2 rst as a single-channel operation.
1-7Chapter 1: Product introduction
Page 18
1.4.2 Memory congurations
You may install 1GB, 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 conguration. Any excess memory
from the higher-sized channel is then mapped for single-channel operation.
• Due to Intel 2nd Generation processors' behavior, DDR3 2200/2000/1800 MHz memory
module will run at DDR3 2133/1866/1600 MHz frequency as default.
• 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:
- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.
- Install a 64-bit Windows OS when 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 512Mb (64MB) 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 2.4 Ai Tweaker menu for manual memory frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full memory
Side(s): SS - Single-sided DS - Double-sided DIMM support:
• 1 DIMM: Supports one (1) module inserted into any slot as Single-channel memory
conguration. We suggest that you install the module into A2 slot.
• 2 DIMMs: Supports two (2) modules inserted into either the blue slots or the black slots as
one pair of Dual-channel memory conguration. We suggest that you install the
modules into slots A2 and B2 for better compatibility.
• 4 DIMMs: Supports four (4) modules inserted into both the blue and black slots as two pairs of
Dual-channel memory conguration.

1.5 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 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.
1-15Chapter 1: Product introduction
Page 26
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. 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 will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.5.3 PCI Express x1 slot
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that
comply with the PCI Express specications.
1.5.4 PCI Express x16 slot
This motherboard has a PCI Express 3.0/2.0 x16 slot that supports PCI Express 3.0/2.0 x16
graphic cards complying with the PCI Express specications.
In single VGA card mode, use the PCIe 3.0/2.0 x 16_1 slot (navy blue) for a PCIe x16 graphics
card to get better performance.

1.6 Onboard switches
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. MemOK! switch
Installing DIMMs that are incompatible with the motherboard may cause system
boot failure, and the DRAM_LED near the MemOK! switch lights continuously. Press
and hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic
memory compatibility tuning for successful boot.
• Refer to section 1.8 Onboard LEDs for the exact location of the DRAM_LED.
• The DRAM_LED also lights when the DIMM is not properly installed. Turn off the system
and reinstall the DIMM before using the MemOK! function.
• The MemOK! switch does not function under Windows™ OS environment.
• During the tuning process, the system loads and tests failsafe memory settings. It takes
about 30 seconds for the system to test one set of failsafe settings. If the test fails,
the system reboots and test the next set of failsafe settings. The blinking speed of the
DRAM_LED increases, indicating different test processes.
• Due to memory tuning requirement, the system automatically reboots when each timing
set is tested. If the installed DIMMs still fail to boot after the whole tuning process, the
DRAM_LED lights continuously. Replace the DIMMs with ones recommended in the
Memory QVL (Qualied Vendors Lists) in this user manual or on the ASUS website at
www.asus.com.
• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn off
the computer and unplug the power cord for about 5–10 seconds.
• If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot
and load BIOS default settings. A messgae will appear during POST reminding you that
the BIOS has been restored to its default settings.
• We recommend that you download and update to the latest BIOS version from the
ASUS website at www.asus.com after using the MemOK! function.
1-17Chapter 1: Product introduction
Page 28
1.7 USB BIOS Flashback
USB BIOS Flashback allows you to easily update the BIOS without entering the BIOS or
operating system. Just connect the USB storage device containing the BIOS le to the USB
port, press the BIOS Flashback switch, and the BIOS is updated automatically.
1 Install USB BIOS Flashback wizard from the support DVD and download the latest
BIOS le to a USB ash drive.
2 Connect the USB ash drive to the bottom of USB2.0 port (LAN1_USB2_78 connector)
at the rear panel.
3 Press the USB Flashback switch for three seconds until the FLBK_LED ashes. The
FLBK_LED goes out when the BIOS update is completed.
1-18
1. Do not disconnect the USB ash drive or power system, or move the CLRTC jumper
during the BIOS updating process. Doing so will interrupt the BIOS updating process. In
case of interruption, follow the steps again to update the BIOS.
2. If FLBK_LED ashes for ve seconds and turns into a stable light, this indicates
that USB BIOS Flashback is not working properly due to improper USB ash drive
connection, BIOS le name error, or incompatible BIOS le format. If this happens,
restart the syetem.
3. BIOS updating poses some risks. If the BIOS program is damaged during the updating
process and the system fails to reboot, please contact your local ASUS Service Center
for assistance

1.8 Onboard LEDs
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.
2. DRAM LED (DRAM_LED)
The DRAM_LED lights up when the DIMM is not properly installed. Turn off the system
and reinstall the DIMM before using the MemOK! function.
1-19Chapter 1: Product introduction
Page 30
1.9 Jumpers
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!
1-20
• 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.
