Safety information

Electrical safety
To prevent electric shock hazard, disconnect the power cable from the electric outlet
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices could interrupt the grounding circuit.
Ensure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.
If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
Operation safety

frequency as default.
** DDR3 1600MHz and higher memory frequency is supported by Intel
PCI Express® 3.0
PCI Express® 3.0 (PCIe 3.0) is the latest PCI Express bus standard with improved encoding schemes that provide twice the performance of the current PCIe 2.0. The total bandwidth for a x16 link reaches a maximum of 32Gb/s, double the 16 Gb/s of PCIe 2.0 (in x16 mode). As such, PCIe 3.0 provides userss an unprecendented data speeds, combined with the convenience and seamless transition offerred by complete backward compatibility with PCIe
1.0 and PCIe 2.0 devices. PCIe 3.0 will become a must-have feature for users who wish to
improve and optimize graphic performance, as well as have the latest technology available to
them.
* PCI 3.0 speed is supported by Intel® 3rd generation CoreTM processors.
S/PDIF out connector at the back I/O
This motherboard provides convenient connectivity to external home theater audio systems via the optical S/PDIF (SONY-PHILIPS Digital Interface) out connecor at the back I/O. The
®
3rd generation processors.
1-2 Chapter 1: Product introduction
S/PDIF transfers digital audio without converting it to analog format and keeps the best signal quality.
Gigabit LAN solution
The onboard LAN controller is a highly integrated Gb LAN controller. It is enhanced with an
ACPI management function to provide efcient power management for advanced operating
systems.
8-channel high denition audio
The onboard 8-channel HD audio (High Denition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output and jack-detect feature that automatically detects and identies what types of peripherals are plugged into the audio I/O jacks and noties users of inappropriate connection, which means there will be no more
confusion of Line-in, Line-out, and Mic jacks.
100% All High-quality Conductive Polymer Capacitors
This motherboard uses all high-quality conductive polymer capacitors for durability, improved lifespan, and enhanced thermal capacity.
Complete USB 3.0 Integration
ASUS facilitates the strategic USB 3.0 accessibility for both the front and rear panel – 4 USB
3.0 ports in total. Experience the latest plug & play connectivity at speeds up to 10 times faster than USB 2.0. P8H77-M affords greater convenience to high speed connectivity.
1.3.2 DIGI+ VRM Digital Power Desigh
All-new digital CPU power controls work perfectly together to match digital power signal
(SVID) requests from the CPU, with ultra-fast sensing and response efciently delivering
precision power. Accurate delivery reduces waste, and provides more stable CPU Vcore voltages.

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.

1.5 Motherboard overview

P8H77-M
Before you install the motherboard, study the conguration of your chassis to ensure that the motherboard ts into it.
Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components.

1.5.1 Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.

1.5.2 Screw holes

Place eight screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards the rear of the chassis

1.6 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA1155 socket designed for the Intel® Second/Third Generation Core™ i7 / Core™ i5 / Core™ i3/ Pentium
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.

1.7.1 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
Recommended memory congurations
One DIMM:
We recommend you install one memory module in either of the blue slots (DIMM_A2 or DIMM_B2) to get better performance.
Two DIMMs (dual-channel operation):
Four DIMMs (dual-channel operation):
ASUS P8H77-M 1-15
1.7.2 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.
• According to Intel CPU specication, 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 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.
