coffee lake ASROCK FATAL1TY K4 Z170 BIOS MOD COFFEE

[Zlucas01]

Hi, this is the first time there. Starting with that I have a Pc build with:

I5 6400, Rx480 4gb, 12gb ram, Z170 Asrock Fatal1ty K4, Silentstorm Icewind 630w, SSD and HDD. I have a custom BIOS to overclock my i5 6400 to 4.3ghz using BCLK. 

I want to get an i5 9600k (and overclock it), I already know riskes of vrm etc..but I really want to get a 9th intel working on my z170. I saw a video thst shows how to do phisically, but i am confused, do i have to solder pins and other? How I make a custom bios to avoid cores limits of z170 and other? Please help me, really appreciate.

Is this guide working?

And is updating bios to latest version and get a i7 7700k better than i5 9600k? Sorry for bad english..
