AMD® FXT /PhenomTII /AthlonTII /SempronT 100 Series Processors.
This motherboard supports AMD® AM3+multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransportT 3.0 based system bus. This motherboard also supports AMD® CPUs in the new 32nm manufacturing process.

HyperTransportT 3.0 technology provides 2.6 times more bandwidth than HyperTransportT 1.0, radically improving system efficiency to create a smoother, faster computing environment.

System Level Energy Saving
The ASUS EPU (Energy Processing Unit) provides total system power management by detecting current PC loadings and intelligently moderating power usage for critical PC components in real-time-helping save power and money!

Dual-Channel DDR3 2000(O.C.) support.
The motherboard supports DDR3 memory that features data transfer rates of 2000(O.C.)/1866(O.C.)/1800(O.C.)/1600(O.C.)/1333/1066 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance.

ASUS Turbo Key allows the user to turn the PC power button into an overclocking button. After the easy setup, Turbo Key can boost performances without interrupting ongoing work or games - with just one touch!!

Intelligently Unlocks True Core Performance
ASUS Core Unlocker simplifies the activation of a latent AMD® CPU-with just pressing a key. Enjoy an instant performance boost by simply unlocking the extra cores, without performing complicated BIOS changes.

Simply update BIOS from a USB flash disk before entering the OS
EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility.

ASUS Anti-Surge Protection.
Anti-Surge Protection Design detects overvoltage conditions and prevents voltage surges from spreading in real time. It also actively cuts off the overvoltage supply to protect the system.
1. Real-time over voltage detection.
2. Active protection against potential damage to your motherboards and systems.

8-channel high definition audio.
The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output and jack-detect feature that automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, which means there will be no more confusion of Line-in, Line-out, and Mic jacks.

Simply restore corrupted BIOS data from USB flash disk
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip.

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.

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.
