Well. That's new info. I'll think about it.. Thanks for the time though.
From what I have heard, this board can overclock locked Skylake CPUs via BCLK. I have not tried this and a specific BIOS version is needed." Not exactly right. The bios update will only work with the Z170-A version.
I have seen numerous reports indicating that the Z170N Gaming 5 Wifi will allow overclocking with a few specific BIOS versions.
A few exemples:

I did check out your links but none of them really indicates much success with a bios update with this particular board. My post was only to inform not to criticise. Good luck with you listing.
I decided to try it to dispel any uncertainty and can confirm that it works, I will add proof to the post.
