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.

2.2.2 Central Processing Unit (CPU)

P8B75-V

P8B75-V CPU socket LGA1155

The motherboard comes with a surface mount LGA1155 socket designed for the Intel®
2nd/3rd Generation Core™ i7 / Core™ i5 / Core™ i3 processors.

Chapter 2

Ensure that all power cables are unplugged before installing the CPU.

• The LGA1156 CPU is incompatible with the LGA1155 socket. DO NOT install a
LGA1156 CPU on the LGA1155 socket.

• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.

• Keep the cap after installing the motherboard. ASUS will process Return Merchandise

Authorization (RMA) requests only if the motherboard comes with the cap on the

LGA1155 socket.

• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.

Recommended memory congurations

Chapter 2

ASUS P8B75-V

2-5

Memory congurations

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 conguration. 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 maximum 32GB memory capacity can be supported with 8GB or above DIMMs.
ASUS will update the memory QVL once the DIMMs are available in the market.

• 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
frequency adjustment.

• For system stability, use a more efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.

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

key during the boot process and enter BIOS setup to re-

<Del>

Chapter 2

ASUS P8B75-V

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 CPU Parameter Recall (C.P.R.) feature.
Shut down and reboot the system, then the BIOS automatically resets parameter
settings to default values.

2.2.6 Onboard switches

P8B75-V

P8B75-V 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.

2-14

• 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.

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 section 2.2.8 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 in the Advanced Mode screen or from the
Advanced Mode button in the EZ Mode screen.
