Are you sure the diff BIOS revisions didn't go and make change(s) in the BIOS itself that have gone overlooked and or unnoticed by you?

That'd be considered odd that a BIOS revision does what you describe, w/o the diff rev. needing some more attention from you.

I've got Z170 Extreme4 with bios 1.80, and several of my USB ports doesnt work (2 on back panel, and one on front panel). They still dont work untill bios 2.40, but after - works. I need exactly bios 1.80 because of OC perfomance. And I need to fix it without updating the bios. Please help.
