2.1 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.

The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets.

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 congurations

We recommend that you install the memory modules from the blue slots for better
overclocking capability.

Chapter 2

ASUS F2A85-V PRO 2-5

Memory congurations

You may install 1GB, 2GB, 4GB and 8GB unbuffered 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.

• We recommend that you install the memory modules from the blue slots for better
overclocking capability.

• 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 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 efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.

F2A85-V PRO

F2A85-V PRO Clear RTC RAM

1 2 2 3

Normal

(Default)

Clear RTC

CLRTC

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 C.P.R. (CPU Parameter Recall) feature. Shut
down and reboot the system so the BIOS can automatically reset parameter settings to
default values.

2.2.6 Onboard switches

F2A85-V PRO

F2A85-V PRO MemOK! switch

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

Chapter 2

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

• 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 (Qualied 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 ASUS
website at www.asus.com after using the MemOK! function.

2.4 Starting up for the rst time

1. After making all the connections, replace the system case cover.

2. Be sure 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 or POST. While the tests are running, the

BIOS beeps (see the BIOS beep codes table below) 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.

7. At power on, hold down the <Delete> key to enter the BIOS Setup. Follow the
instructions in Chapter 3.

2.5 Turning off the computer

While the system is ON, pressing the power switch for less than four seconds puts the system
on sleep mode or soft-off mode, depending on the BIOS setting. Pressing the power switch
for more than four seconds lets the system enter the soft-off mode regardless of the BIOS
setting.

Chapter 3: BIOS setup

3.1 Knowing BIOS

The ASUS UEFI BIOS offers a user-friendly interface that goes beyond traditional

keyboard-only BIOS controls to enable more exible and convenient mouse input. Users

can easily navigate the UEFI BIOS with the same smoothness as their operating system.

The term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot device
conguration 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 modication. 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 rst 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 sectionSee 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.
