Installing DIMMs that are not compatible with the motherboard may cause system
boot failure, and the DRAM_LED near the MemOK! button lights continuously. Press
the MemOK! button until the MEMOK_LED memory compatibility tuning for successful
boot.
Chapter 1
• Refer to section 1.2.8 Onboard LEDs for the exact location of the MEMOK_LED.
• The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! function.
• The MemOK! button 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 MEMOK_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 fails to boot up due to BIOS overclocking, press the MemOK! button
to boot and load the BIOS default settings. A message 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.

4. 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 <Del> key during POST. It also allows you to turn on or turn off your system and
conveniently enter the BIOS during boot-up.
Ensure to save your data before using the DirectKey button.
• 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 3.8 Boot Menu for details about setting the DirectKey default
function.

1.2.7 Jumper
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.
Chapter 1
1-28
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 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.

is being written into or read from the hard disk drive. The LED does not light up when
there is no hard disk drive connected to the motherboard or when the hard disk drive
does not function.

2.4 Starting up for the rst time
1. After making all the connections, replace the system case cover.
2. Ensure that all switches are off.
3. Connect the power cord to the power connector at the back of the system chassis.
4. Connect the power cord to a power outlet that is equipped with a surge protector.
5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power
6. After applying power, the system power LED on the system front panel case lights up.
For systems with ATX power supplies, the system LED lights up when you press the
ATX power button. If your monitor complies with the “green” standards or if it has a
“power standby” feature, the monitor LED may light up or change from orange to green
after the system LED turns on.
The system then runs the power-on self tests (POST). While the tests are running, the
BIOS beeps (refer to the BIOS beep codes table) or additional messages appear on
the screen. If you do not see anything within 30 seconds from the time you turned on
the power, the system may have failed a power-on test. Check the jumper settings and
connections or call your retailer for assistance.

3.1 Knowing BIOS
The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO NOT change the default BIOS settings except in the following
circumstances:
qAn error message appears on the screen during the system bootup and requests you
to run the BIOS Setup.
qYou have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
When downloading or updating the BIOS le, rename it as M6H.CAP for this motherboard.

• The BIOS setup screens shown in this section are for reference purposes only, and
may not exactly match what you see on your screen.
• Ensure that a USB mouse is connected to your motherboard if you want to use the
