  • DDR2 1366+ Support --The World's Fastest DDR2 Motherboard
    Delivering native support for DDR2 memory up to 1366+MHz, GIGABYTE Ultra Durable 3 series motherboards allow users to easily reach higher memory frequencies at lower voltages; achieving higher memory performance with lower power consumption to run even the most memory intensive applications such as high-definition video and 3D games with ease.
    * Please refer "Memory Support List" for memory support information.


  • 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.
    (Note1)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.
    (Note2)Ultra TPM feature is optional due to different regional policy.


  • 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.


  • 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.
