Underclocking on a H-chipset.

[MattCookR1]

hi there, my first post here. I want to know if underclocking is ever possible on H-chipset with an unlocked CPU, specially on the newer H170 chipset. I have read that Z-chipset allows you to overclock the chip but other chipsets can perfectly fine underclock any chip.

Can anyone confirm that to me?, specially if you are owner of the new Skylake chipsets H170, I can't find anything concrete about it on the net, I'm starting to believe I'm the first person on earth to have such a question. Thank you.
