GIGABYTE Ultra Durable 3 Classic (CPU VRM) motherboards promise to provide the stability, reliability and longevity essential to meet the power needs of high-end processors and other components running today's most demanding applications and games.
  • Supports Dual Channel DDR2 1200+
    Experience the advanced technology of DDR2 1200+ memory, featuring faster speeds and higher data bandwidth, which delivers superior performance for the most demanding applications.
    * DDR2 1200+ is supported with combination of AM3 processors and qualified memory modules, please refer "Memory Support List" for detail memory support information.
  • PCI-E 2.0 Graphics Interface
    PCI-E 2.0 doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s, meaning a x32 connector can transfer data at up to 16 GB/s in each direction. PCI-E 2.0 also features improvements to the point-to-point data transfer protocol and its software architecture.


  • 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 4-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 4-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.


  • 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.

  • Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
  • ErP Lot 6 support
    The ErP (also known as Energy-Related Products Directive) is part of the European Union's environmental regulations policy. It is based on concern for the environmental as the proliferation of electronic devices continues, and how to improve energy efficiency for a better and greener life. GIGABYTE supports ErP and produces motherboards that help you effectively improve system efficiency.
