  • Ultra Durable 3 – Classic (CPU VRM)


    GIGABYTE Ultra Durable 3 series motherboards once again lead the motherboard industry for the highest quality and most innovative motherboard design. Featuring the industry’s first consumer desktop motherboard design to introduce 2 ounces of copper for both the Power and Ground layers, delivering a dramatically lower system temperature, improved energy efficiency and enhanced stability for overclocking.GIGABYTE Ultra Durable 3 Classic (CPU VRM) motherboards are equipped with the GIGABYTE Ultra Durable signature features including Japanese Solid Capacitors around CPU VRM boasting an operational life time of more than 50,000 hours, and GIGABYTE patented DualBIOS™ technology (providing dual hardware BIOS protection). 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
    신세대 EasyTune 6의 경우, 기가바이트는 EasyTune의 인터페이스를 간결, 직관, 상세하게 표현했다. 이에 기존의 버전에 비해 어떤 사용자라도 각종 오버클럭 프로파일을 손쉽고 빠르게 조절할 수 있게 되었다. 또한 EasyTune™ 6은 보다 상세한 하드웨어 정보 디스플레이 항목이 있어서 오버클로킹을 하지 않아도 훌륭한 하드웨어관리 유틸리티이다.


  • 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 지원
    ErP은 에너지 관련 제품(Energy-related Products)을 의미하며, EU환경보호법률에서 지정한 규격 중 하나이다. 현재 전자제품이 대량 사용 및 보급되면서, 에너지 효율 제고 및 환경의 지속가능한 발전이 최대 이슈가 되고 있다. 기가바이트의 ErP지원 메인보드는 시스템 성능과 절전효율을 제고할 수 있다.
