Gigabyte's entire fleet of AMD 9-series chipset socket AM3+ motherboards, launched in 2011 with AMD FX "Bulldozer" processors shipped with Phoenix AwardBIOS, even as other motherboard makers such as ASUS, MSI, Biostar, and Sapphire moved on to AMI Aptio UEFI BIOS. Gigabyte's AwardBIOS implementation did feature the company's biggest excuse for delayed implementation of UEFI across its entire product line, HybridEFI: a BIOS tweak that lets you boot from volumes bigger than 2 TB.

In the wake of second generation FX "Vishera" processors and Windows 8 with its UEFI-enhancements, Gigabyte finally decided to make amends to its socket AM3+ motherboard lineup, by introducing revisions of existing motherboard models, featuring AMI Aptio UEFI BIOS, and its dual-UEFI redundant BIOS technology that protects against failed BIOS updates. Gigabyte's UEFI-equipped AM3+ motherboards will follow revision number scheme from 3.xx, jumping from its canonical revision number scheme of 1.xx. For example, pictured below is the newly launched 970A-D3 Rev 3.0, which jumped from Rev 1.4. The revisions are largely identical to their predecessors, except of course implementation of the AMI Aptio UEFI BIOS and dual-UEFI feature. When buying, look for the revision number in the main barcode sticker on the box, and on the bottom-left corner of the motherboard itself.
