    * DDR2 1200+ is supported with combination of AM3 processors and qualified memory modules, please refer "Memory Support List" for detail memory support information.
  • 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.
