EPU 4 Engine System Level Energy SavingThe 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! Turbo Key Touch-n-Boost!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!! 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. Core Unlocker 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. EZ Flash 2 Simply update BIOS from a USB flash disk before entering the OSEZ 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. Q-Fan ASUS Q-Fan technology intelligently adjusts fan speeds according to system loading to ensure quiet, cool and efficient operation. 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. CrashFree BIOS 3 Simply restore corrupted BIOS data from USB flash diskThe 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. Support 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.* Use the chassis with HD audio module in the front panel to support 8-channel audio output. 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.
