  • Interface graphique PCI-E 2.0
    L'interface PCI-E 2.0 double la bande passante de la norme PCI-Express standard, en passant de 2.5 Gbit/s à 5 Gbit/s, un connecteur x32 pouvant transférer jusqu'à 16 GB/s de données.


  • 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.
  • The Industry's Leading All-Solid Capacitor motherboard Design
    To ensure a longer operation life time for systems in daily operation and boost system stability under extreme conditions, this platform adopts cutting-edge Conductive Polymer Aluminum Solid Capacitors from the world's leading vendors. With these high-qualitycomponents , users can take advantage of better electronic conductivity and excellent heat resistance for enhanced system durability.

  • Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
  • Hardware Overvoltage Control ICs
    Hardware Overvoltage Control ICs which provide more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control. In addition, 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.
