  • 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.
  • 2 Power Phases for Both North Bridge and Memory
    GIGABYTE P45 motherboards are equipped with 2-Phase power for the North Bridge and memory, allowing users to reach higher memory frequencies and enjoy better performance. Compared with only one phase solutions, this ensures longer power component lifespan and higher overclockability due to cooler working temperatures and better efficiency.


  • High Velocity 2X Bandwidth Boost
    The dual Gigabit LAN with Teaming functionality enabled allows 2 single connections to act as 1 single connection for double bandwidth, improving overall throughput.

    Prevents network downtime by transferring the workload from a failed port to a working port.

    Receive Side Scaling balances the network traffic load evenly between 2 CPU cores in order to improve performance.

    Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
    (Note) To enable Teaming or Bonding (IEEE 802.3ad Link Aggregation) feature, it is required the connected network switch or router device supports the IEEE 802.3ad LACP standard. Please refer to your network switch or router device manual for further details.
