It provides improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability. Anti-Surge Protection Protect Your Device 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. Dual-Channel DDR3 1333 / 1066 support The motherboard supports DDR3 memory that features data transfer rates of 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. EPU Tap into the world’s first real time PC power saving engine through AI Suite II utility. Get total system power savings by automatically detecting current PC loadings and intelligently moderating power consumption. This also reduces fan noise and extends component longevity. AI Suite II With its fast user-friendly interface, ASUS AI Suite II consolidates all the exclusive ASUS features into one simple to use software package. It allows you to supervise overclocking, energy management, fan speed control, voltage and sensor readings. This all-in-one software offers diverse and ease to use functions, with no need to switch back and forth between different utilities. UEFI BIOS (EZ Mode) Exclusive to ASUS motherboards, its UEFI (Unified Extensible Firmware Interface) is the first ever mouse-controlled graphical BIOS interface designed with dual selectable modes. It delivers a user-friendly interface that goes beyond traditional keyboard-only BIOS controls to enable more flexible and convenient input with quick scrolling. Users can easily navigate the UEFI BIOS with the smoothness of their operating system. Quick and simple overclocking and setup sharing is facilitated by the F12 hotkey BIOS snapshot feature. The exclusive EZ Mode displays frequently-accessed setup info, while the Advanced Mode is for experienced performance enthusiasts that demand far more intricate system control, including detailed DRAM information.Supports Hard Drives over 2.2TBASUS UEFI BIOS natively supports hard drives larger than 2.2TB in 64-bit, with full storage space utilization helping deliver far more exciting computing than traditional BIOS versions.Exclusive ASUS Interface• EZ Mode - gives easy access to selectable, optimized system modes, clear system info display and drag and drop boot prioritizing• Advanced Mode - for experienced performance enthusiasts that demand intricate system settings Fan Xpert Active Quiet & CoolASUS Fan Xpert intelligently allows users to adjust the CPU fan speed according to different ambient temperature , which is caused by different climate conditions in different geographic regions and system loading.Built-in variety of useful profiles offer flexible controls of fan speed to achieve a quiet and cool environment. 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. 100% All High-quality Conductive Polymer Capacitors This motherboard uses all high-quality conductive polymer capacitors for durability, improved lifespan, and enhanced thermal capacity. 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.
