  • DDR2 1366+ Support --The World's Fastest DDR2 Motherboard
    Delivering native support for DDR2 memory up to 1366+MHz, GIGABYTE Ultra Durable 3 series motherboards allow users to easily reach higher memory frequencies at lower voltages; achieving higher memory performance with lower power consumption to run even the most memory intensive applications such as high-definition video and 3D games with ease.
    * Please refer "Memory Support List" for memory support information.


  • Dynamic Energy Saver Advanced
    GIGABYTE Dynamic Energy Saver Advanced provides better energy saving capabilities and enhanced system performance. GIGABYTE Dynamic Energy Saver Advanced is the world’s only motherboard energy saving technology with hardware-based Dynamic 6-Gear* Switching. With support for VRD 11.1, GIGABYTE’s DES Advanced allows the motherboard to switch to 1 Gear phase switching during idle, allowing for a dramatic increase in power savings.

    GIGABYTE has also retooled Dynamic Energy Saver to allow overclockers to experience the benefits of multi-gear power phase switching while overclocking, providing ultra stable, ultra smooth overclocking performance.
    * The 6-Gear feature may vary by model. Gear 1 phase switching requires 45nm processors with PSI signal enabled.


  • Quick and Effortless Overclocking with One Click
    GIGABYTE Quick Boost provides 3 levels of CPU performance enhancement; a simple click on the desired level delivers quick and effortless overclocking for novice and experienced users alike.
  • EasyTune6
    GIGABYTE has completely redesigned EasyTune6 from the ground up to make it easier than ever to manage and monitor your hardware resources as well as tweak your system settings in order to achieve maximum system performance. Whether you are an overclocking enthusiast, or a computer novice, EasyTune6 provides the tools you need to quickly and effortlessly fine tune your system.
  • Hardware OverVoltage Control IC-- Enabling Extreme Overclocking
    GIGABYTE Hardware Overvoltage Control ICs featuring more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control, which means there is no delay compared to the GPIO controller in past implementations. In addition, GIGABYTE’s Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.


  • DualBIOS™ - Patented Dual Hardware BIOS Protection
    DualBIOS™ is a GIGABYTE patented technology that automatically recovers BIOS data when main BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE DualBIOS™ allows quick and seamless recovery from BIOS damage or failure due to viruses or improper BIOS updating.
