The new B3 version GIGABYTE 6 Series motherboards have been totally redesigned and renamed so that they can easily be distinguished from the older B2 versions through the signature “B3” at the end of the model name. For example, the GA-P67A-UD7 has been replaced by the GA-P67A-UD7-B3and the GA-H67A-UD3H has been replaced by the GA-H67A-UD3H-B3. The new model name is highly visible on the retail box, PCB, in the BIOS at start up and on applications such as the GIGABYTE 6 Series SATA Check utility and CPU-Z.
GIGABYTE 6 Series SATA Check Utility
Immediately after learning about the B2 stepping Intel® 6 Series chipset design error, GIGABYTE released the easy to use GIGABYTE 6 Series SATA Check utility that helps to optimize SATA performance by identifying the white SATA 6Gbps that can be used, while advising users not to use the affected Intel® PCH SATA ports. As the new B3 versions on 6 Series motherboards start to ship, GIGABYTE just released an updated 6 Series SATA Check utility that also identifies the chipset and its stepping (either B2 or B3).
