Memory congurations
You may install 1GB, 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the
DIMM sockets.
Chapter 2
• 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
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).
• 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
3.4 Ai Tweaker menu
for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full

• Refer to section
• 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 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

2.2.7 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.
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.

3.1 Knowing BIOS
The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with the 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. Users can easily
navigate the new UEFI BIOS with the same smoothness as their 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 optimum
performance. We recommend that you not change the default BIOS settings except in
the following circumstances:
• An error message appears on the screen during the system bootup and requests you to
run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
3.2 BIOS setup program
A BIOS setup program is provided for BIOS item modication. When you start up the
computer, the system provides you with the opportunity to run this program. Press <Del>
during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues
with its test routines.
