In preparation for Intel's upcoming 22nm processor refresh, Biostar wants to get the word out that each and every one of its 6 Series motherboards fully support native PCI-E Gen. 3 when paired with chipzilla's next generation Ivy Bridge CPUs. According to Biostar, each board is able to pass the signal test of PCI-E Gen. 3 technology without any hardware changes, unlike at least one other board maker who was accused of having "fake" PCI-E Gen. 3 support.
PCI-E Gen. 3 claims are sometimes a point of controversy, just as we saw in September when MSI called shenanigans on Gigabyte's implementation. MSI put together a boatload of slides calling Gigabyte out for using "fake" Gen. 3 switches and other non-compliant hardware. MSI then demonstrated that by plopping a 22nm CPU into a board that isn't fully PCI-E Gen. 3 compliant, it drops down to Gen 1. x8.
This is why Biostar is making it a point to announce that its 6 Series boards are up to snuff. The list of mainboards that fully support native PCI-E Gen. 3 is long and includes the following boards:
