  • Qualified for Windows® 7
    The motherboard qualified for WHQL (Windows Hardware Quality Labs) certification of Windows 7 from Microsoft®, setting the standard for future Windows 7 certified motherboards...more
  • Smaller, Faster and More Efficient
    GA-G41MT-ES2H motherboards paired with Intel 45nm CPUs deliver the very best platform for multitasking, multimedia and high performance gaming. Not only do GIGABYTE's latest motherboards based on Intel Eaglelake chipsets all support Intel's new generation, 45nm multi-core processors.
  • Supports Dual Channel DDR2 1200+
    Experience the advanced technology of DDR2 1200+ memory, featuring faster speeds and higher data bandwidth, which delivers superior performance for the most demanding applications.
    * DDR2 1200+ is supported with combination of AM3 processors and qualified memory modules, please refer "Memory Support List" for detail memory support information.
  • PCI-E 2.0 Graphics Interface
    PCI-E 2.0 doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s, meaning a x32 connector can transfer data at up to 16 GB/s in each direction. PCI-E 2.0 also features improvements to the point-to-point data transfer protocol and its software architecture.


  • 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.


  • 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.

  • Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
  • Hardware Overvoltage Control ICs
    Hardware Overvoltage Control ICs which provide more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control. In addition, Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.
  • EasyTune6
    신세대 EasyTune 6의 경우, 기가바이트는 EasyTune의 인터페이스를 간결, 직관, 상세하게 표현했다. 이에 기존의 버전에 비해 어떤 사용자라도 각종 오버클럭 프로파일을 손쉽고 빠르게 조절할 수 있게 되었다. 또한 EasyTune™ 6은 보다 상세한 하드웨어 정보 디스플레이 항목이 있어서 오버클로킹을 하지 않아도 훌륭한 하드웨어관리 유틸리티이다.
