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.

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.
ASUS EZ Flash 2
ASUS EZ Flash 2 is a utility that allows you to update the BIOS without using an OS-based utility.
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.
1.3.3Other special features
LucidLogix Virtu MVP
LucidLogix Virtu MVP featuring HyperFormance™ Technology boosts your PCIe graphics card up to 60% beyond its original performance. Designed for Intel® processor graphics and Windows® 7 PCs, it perfectly combines the performance of discrete graphic cards with fast computing iGPU. Also, with newly designed Virtual Sync, users can enjoy a smoother gaming experience by eliminating tearing artifacts. LucidLogix Virtu MVP can also dynamically assigns tasks to the best available graphics resource, based on power, performance, and system load. This allows users to fully utilize 3x faster video conversion with Intel® Quick Sync Video 2.0 technology while retaining high-end 3D rendering and gaming performance, provided by both NVIDIA and AMD graphic cards. When the PCIe graphic cards are not required, the graphics control switches to the Intel® processor graphics, reducing the PCIe graphics power use down to zero, making the system more environment-friendly.
For users searching for perfection, LucidLogix Virtu MVP provides great graphical performance, and best quality and efficiency.
*LucidLogix Virtu MVP supports Windows® 7 operating system.
**Intel® Quick Sync Video feature is supported by 3rd/2nd generation Intel® Core™ processor family.

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 |

Chapter 1: Product introduction |
1.6Central 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.
P8H77-M LE
P8H77-M 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.

1.7System memory
1.7.1Overview
The motherboard comes with two 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 figure illustrates the location of the DDR3 DIMM sockets:

Channel A |
DIMM_A1 |
Channel B |
DIMM_B1 |
P8H77-M LE 240-pin DDR3 DIMM sockets
1.7.2Memory 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 ChannelAand 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.
•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 Profile 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® 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.
•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 (2 DIMMs) or overclocking condition.
