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 configurations
2-5
ASUS SABERTOOTH Z77
Memory configurations
You may install 1GB, 2GB, 4GB and 8GB unbuffered and 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 configuration. 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:
- 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 efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

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.
2.
Turn OFF the computer and unplug the power cord.
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.
4.
Plug the power cord and turn ON the computer.
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.
2-14
Chapter 2: Hardware information
2.2.6
Onboard switch
The onboard switch allows you to fine-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.
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 2.2.7 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 (Qualified 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.

Onboard LEDs
1.
Standby Power LED
The motherboard comes with a standby power LED. The green LED 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.
POST State LEDs
The POST State LEDs of CPU, DRAM, VGA card, and HDD indicate key components
status during POST (Power-on Self Test). If an error is found , the LED next to the
error device will continue lighting until the problem is solved. This user-friendly design
provides an intuitional way to locate the root problem within a second.

goes out when the BIOS update is completed.
1. Do not disconnect the USB flash drive or power system, or press the CLR_CMOS
button 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 LED flashes for five seconds and turns into a stable light, this indicates that USB
BIOS Flashback is not working properly due to improper USB flash drive connection,
BIOS file name error, or incompatible BIOS file format. If this happens, restart the
system.
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.

Knowing BIOS
The new ASUS UEFI BIOS is an Unified Extensible Firmware Interface that complies with
UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-
only BIOS controls to enable more flexible 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 specified.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device configuration, overclocking settings, advanced power management, and boot device
configuration 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 modification. 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.
If you wish to enter Setup after POST, press <Ctrl> + <Alt> + <Delete>, or press the reset
button on the system chassis to restart the system. You can also turn the system off and then
turn it back on to restart the system. Do this last option only if the first two failed.
•
•
•
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
mouse to control the BIOS setup program.
If the system becomes unstable after changing any BIOS setting, load the default
settings to ensure system compatibility and stability. Select the Load Optimized
Defaults item under the Exit menu. See section 3.9 Exit Menu for details.
•
If the system fails to boot after changing any BIOS setting, try to clear the CMOS and
reset the motherboard to the default value. See section 2.2.5 Jumper for information
on how to erase the RTC RAM.
•
The BIOS setup program does not support the bluetooth devices.
The BIOS setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various submenus and select from the
available options using a keyboard or a USB mouse.
The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode.
You can change modes from the Exit menu or from the Exit/Advanced Mode button in the
EZ Mode/Advanced Mode screen.
