  • 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.


  • Ultra TPM - Industry’s highest level of data Security via onboard TPM
    TPM function is optional due to different regional policy
    • Maximum level of data protection with 2048 bit encryption
    • Security, manageability and flexibility that surpasses software-based encryption
    • Portable User Key to protect data when away from your system
    • Additional backup of user key in BIOS in case of misplaced key
    • After creating the password(s) and key(s) associated the TPM, be sure to store them in a secure location and back them up. Loss of the password(s) or the key(s) will render the files encrypted via the TPM unable to be cracked or read.
    • Though the TPM delivers the latest data security technology, it does not guarantee data integrity or give hardware protection. GIGABYTE is not liable for loss of encrypted data as a result of hardware damage.
    (Note)If you want to uninstall the Ultra TPM utility, be sure to insert the USB flash drive containing the TPM key into your computer before the uninstallation.


  • High Velocity 4X Bandwidth Boost
    The Quad LAN with Teaming functionality enabled allows 4 single connections to act as 1 single connection for Quad 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.
