ATA (SATA) storage interface. This motherboard delivers up to 6.0 Gb/s data transfer rates. Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of current bus systems.

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. The P8H77-V

LE affords greater convenience to high speed connectivity.

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 users 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 Core™ processors.

1-2	ASUS P8H77-V LE

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 S/PDIF transfers digital audio without converting it to analog format and keeps the best signal quality.

Intel® Smart Response Technology SSD Speed with HDD Capacity

Intel® Smart Response Technology boosts overall system performance by using an installed fast SSD (min 18.6GB available capacity required) as a cache for frequently accessed data. Key benefits include reduced load and wait times, and lower power consumption through the elimination

of unnecessary hard drive spin. This technology combines SSD performance with hard drive capacity, operating up to 6X faster than a hard drive-only system.

*Intel® Smart Response Technology is supported by 3rd/2nd generation Intel® Core™ processor family on Windows® 7™ operating systems.

**Operating systems must be installed on the HDD to launch Intel® Smart Response Technology.

The capacity of the SSD is reserved for caching function.

Intel® Smart Connect Technology

Your computer could receive web updates with fresh content for selected applications, even when setting the system to sleep. This means less time waiting for applications to start, update and sync with the cloud, providing a more efficient way.

Intel® Rapid Start Technology

Allows your computer to quickly resume from a lowe-power hibernate state in seconds. Saving system memory to the designed SSD, provides your computer a faster wake-up response time, while keeping the energy use low.

ATI Quad-GPU CrossFireX™ Support

ATI's CrossFireX™ boosts image quality along with rendering speed, eliminating the need to scale down screen resolution to get high quality images. CrossFireX™ allows higher antialiasing, anisotropic filtering, shading and texture settings. Adjust your display configurations, experiment with the 3D settings, and check the effects with a real-time

3D-rendered previews within ATI Catalyst™ Control Center.

USB 3.0 Boost

New ASUS USB 3.0 Boost technology supports UASP (USB Attached SCSI Protocol), the latest USB 3.0 standard. With USB 3.0 Boost technology, a USB device’s transmission speed is significantly increased up to 170%, adding to an already impressive fast USB 3.0 transfer speed.

ASUS software automatically accelerates data speeds for compatible

USB 3.0 peripherals without the need for any user interaction.

• The USAP standard support varies with models.

• Due to Intel® USB 3.0 controller limitation, USB 3.0 Boost does not support Windows® XP.

ASUS CrashFree BIOS 3

ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to restore a corrupted BIOS file using the bundled support DVD or USB flash disk that contains the latest BIOS file.

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 efficiency requirements in regards to energy consumptions. This is in line with

ASUS vision of creating environment-friendly and energy-efficient products through product design and innovation to reduce carbon footprint of the product and thus mitigate environmental impacts.

1.4Before 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.

1.5Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits 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.

1.5.1Placement 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.

1.5.2Screw holes

Place six 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

1.6Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA1155 socket designed for the Intel®

3rd/2nd Generation Core™ i7/ i5/ i3/ Pentium® / Celeron® processors.

P8H77-V LE

P8H77-V LE CPU socket LGA1155

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.
