    • Designed to automatically deliver the best possible listening experience


  • 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.


  • Ultra TPM - Industry’s highest level of data Security via onboard TPM
    • 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.
