Got my i5 6400 clocked at 4.6Ghz on an Asus Z170 A which is faster than a more expensive 6700k. It's not like it's a big deal except for the false advertisement from Asrock. There is a non-K OC bios for most Z170 boards if not all already.
Did EA really say that? Wow, they really have no clue...With their background, how could someone really believe those claims. Better luck next time EA.
