1.4 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.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings
when the system hangs due to overclocking failure. C.P.R. eliminates the
need to open the system chassis and clear the RTC data. Simply shut
down and reboot the system, and the BIOS automatically restores the
CPU parameters to their default settings.
ErP ready
The motherboard is European Union´s Energy-related Products (ErP)
ready, and ErP requires products to meet certain energy efciency
requirements in regards to energy consumptions. This is in line with
ASUS vision of creating environment-friendly and energy-efcient

ASUS P8B75-M1-8
1.6 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1155 socket designed for the Intel®
3rd/2nd Generation Core™ i7 / Core™ i5 / Core™ i3, Pentium®, Celeron® processors.
Unplug all power cables before installing the CPU.
• 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.

1.7 System memory
1.7.1 Overview
The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption.
The gure illustrates the location of the DDR3 DIMM sockets:
Channel Sockets
Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
1.7.2 Memory congurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM
sockets.
• 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 2.4 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.
• 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.
• 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.
• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.

1.8 Expansion slots
In the future, you may need to install expansion cards. The following sub-sections describe
the slots and the expansion cards that they support.
Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
1.8.1 Installing an expansion card
To install an expansion card:
1. Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already installed in a chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.
4. Align the card connector with the slot and press rmly until the card is completely
seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
1.8.2 Conguring an expansion card
After installing the expansion card, congure it by adjusting the software settings.
1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
2. Assign an IRQ to the card.
3. Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.8.3 PCI slot
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specications.
1.8.4 PCI Express x4 slot
This motherboard supports PCI Express x4 network cards, SCSI cards, and other cards that
comply with the PCI Express specications.
1.8.5 PCI Express x16 slot
This motherboard has a PCI Express 3.0 x16 slot that supports PCI Express 3.0/2.0 x16
graphic cards complying with the PCI Express specications.

1.9 Jumpers
1. Intel® ME jumper (3-pin DIS_ME)
This jumper allows you to enable or disable the Intel® ME function. Set this jumper to
pins 1-2 to enable (default) the Intel® ME function and to pins 2-3 to disable it.

2. 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.
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.
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.

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 1.12 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 (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.
1.11 Onboard switches
Onboard switches allow you to ne-tune performance when working on a bare or open-case
