  • Supports next generation of 45nm AMD AM3 CPU
    This motherboard designs with Split Power Plane, 8+2 phase VRM to support AMD the latest 45nm AM3 Phenom™II series processors, delivering the great performance enchantment to system and ultimate scalability hardware expending.
  • 108dB Signal-to-Noise ratio playback
    GIGABYTE strongly believes that in 2011, HD audio playback is a standard specification, and as such, we have made Blu-ray audio playback a standard for all of our motherboards.
    All of GIGABYTE's 2011 motherboards feature higher capability audio solution with 108dB Signal-to-Noise ratio (SNR) playback quality to deliver high-performance, multi-channel HD audio. SNR is a comparison of the amount of signal to the amount of noise such as hiss present in the signal (expressed in Decibels). A higher SNR equals a better audio experience. For example, 108dB, is a high audio specification, as this means the audio signal is 108dB higher than the level of the noise.
  • DualBIOS™ 3TB+ HDD Support (Hybrid EFI Technology)
    Hybrid EFI Technology combines the benefits of GIGABYTE's mature BIOS platform including stability and compatibility with 3rd party products with 3TB+ HDD support from EFI technology, allowing GIGABYTE to offer the best of both worlds through a quick and easy BIOS update using GIGABYTE's @BIOS utility that is freely available from the GIGABYTE website.
    GIGABYTE DualBIOS™ is a patented technology that automatically recovers BIOS data when the main BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE DualBIOS™ allows quick and seamless recovery from BIOS damage or failure due to viruses or improper BIOS updating. In addition, GIGABYTE DualBIOS™ now supports 3TB+ (terabyte) hard drive booting without the need for partitioning, and enables more data storage on a single hard drive.
  • Turbo XHD- Full Automatic RAID 0/Stripe
