1.2 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.

P8Q77-M2 CPU socket LGA1155

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.

1.5.1 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:

Chapter 1: Product introduction

1.5.2 Memory congurations

You may install 1GB, 2GB, 4GB, and 8GB unbuffered 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 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 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.

• Memory module with memory frequency higher than 2133 MHz and its corresponding
timing or the loaded XMP Prole is not the JEDEC memory standard. The stability and

compatibility of these memory modules depend on the CPU's capabilities and other
installed devices.

• 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

- 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.

• 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.

1.6 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.

1.6.1 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.

1.6.2 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.

1.6.3 PCI slots

The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that

comply with PCI specications.

1.6.4 PCI Express x4 slot

This motherboard supports PCI Express 2.0 x4 network cards, SCSI cards, and other cards

that comply with the PCI Express specications.

Clear RTC

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

• You do not need to clear the RTC when the system hangs due to overclocking. For

1.9 Onboard switches

P8Q77-M2

P8Q77-M2 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.

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 1.10 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.
