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.  
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.  
1.3.1  
Installing the CPU  
The LGA1156 CPU is incompatible with the LGA1155 socket. DO NOT install a LGA1156  
CPU on the LGA1155 socket.

System memory  
1.4.1  
Overview  
The motherboard comes with four Double Data Rate 3 (DDR3) Dual In-line Memory Modules  
(DIMM) slots.  
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  
Install one memory module in slot A2 first as a single-channel operation.  
Chapter 1: Product introduction  
1-7  
 
1.4.2  
Memory configurations  
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 configuration. Any excess memory  
from the higher-sized channel is then mapped for single-channel operation.  
Due to Intel 2nd Generation processors' behavior, DDR3 2200/2000/1800 MHz memory  
module will run at DDR3 2133/1866/1600 MHz frequency as default.  
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  
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 2.4 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.

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.  
1.5.1  
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.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
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 firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
Chapter 1: Product introduction  
1-15  
 
1.5.2  
Configuring an expansion card  
After installing the expansion card, configure 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.  
3.  
Assign an IRQ to the card.  
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, conflicts will arise between the two PCI  
groups, making the system unstable and the card inoperable.  
1.5.3  
PCI Express x1 slot  
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that  
comply with the PCI Express specifications.  
1.5.4  
PCI Express x16 slot  
This motherboard has a PCI Express 3.0/2.0 x16 slot that supports PCI Express 3.0/2.0 x16  
graphic cards complying with the PCI Express specifications.  
In single VGA card mode, use the PCIe 3.0/2.0 x 16_1 slot (navy blue) for a PCIe x16 graphics  
card to get better performance.

Onboard switches  
Onboard switches allow 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.  
1.  
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 1.8 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  
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  
Chapter 1: Product introduction  
1-17  
 
1.7  
USB BIOS Flashback  
USB BIOS Flashback allows you to easily update the BIOS without entering the BIOS or  
operating system. Just connect the USB storage device containing the BIOS file to the USB  
port, press the BIOS Flashback switch, and the BIOS is updated automatically.  
1
2
3
Install USB BIOS Flashback wizard from the support DVD and download the latest  
BIOS file to a USB flash drive.  
Connect the USB flash drive to the bottom of USB2.0 port (LAN1_USB2_78 connector)  
at the rear panel.  
Press the USB Flashback switch for three seconds until the FLBK_LED flashes. The  
FLBK_LED goes out when the BIOS update is completed.  
1. Do not disconnect the USB flash drive or power system, or move the CLRTC jumper  
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 FLBK_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 syetem.  
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

Onboard LEDs  
1.  
Standby power LED (SB_PWR)  
The motherboard comes with a standby power LED that 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.  
DRAM LED (DRAM_LED)  
The DRAM_LED lights up when the DIMM is not properly installed. Turn off the system  
and reinstall the DIMM before using the MemOK! function.

1.9  
Jumpers  
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 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.

This connector is for a chassis-mounted front panel audio I/O module that supports  
either HD Audio or legacy AC`97 audio standard. Connect one end of the front panel  
audio I/O module cable to this connector.  
We recommend that you connect a high-definition front panel audio module to this  
connector to avail of the motherboard’s high-definition audio capability.  
If you want to connect a high-definition front panel audio module to this connector, set  
the Front Panel Type item in the BIOS setup to [HD]. If you want to connect an AC'97  
front panel audio module to this connector, set the item to [AC97]. By default, this  
connector is set to [HD]. See section 2.5.6 Onboard Devices Configuration for details.  
ASUS P8Z77-M

2.  
ATX power connectors (24-pin EATXPWR, 8-pin ATX12V)  
These connectors are for ATX power supply plugs. The power supply plugs are  
designed to fit these connectors in only one orientation. Find the proper orientation and  
push down firmly until the connectors completely fit.  
For a fully configured system, we recommend that you use a power supply unit (PSU)  
that complies with ATX 12 V Specification 2.2 (or later version) and provides a minimum  
power of 350 W.  
DO NOT forget to connect the 8-pin ATX +12V power plug. Otherwise, the system will  
not boot up.  
Use of a PSU with a higher power output is recommended when configuring a system  
with more power-consuming devices. The system may become unstable or may not boot  
up if the power is inadequate.  
If you want to use two or more high-end PCI Express x16 cards, use a PSU with 1000W  
power or above to ensure the system stability.  
If you are uncertain about the minimum power supply requirement for your system,  
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.  
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
