Speaking of ASRock boards, in my experience they are the best. I am waiting for extreme series x299, like Extreme4, 6, 10. I still have AsRock x79 Extreme4 and AsRock x99 Extreme4 and they are rocking awesome since day 1 and both i paid just $170 (On Sale). Again speaking of SkyLake X, lower that BLCK down to 100Mhz and set multiplier to 20x and lower your voltage or in fact use default voltage and do not worry about heat. As I said in the previous article, pushing 10/20 this high goes beyond reasonable. If you guys snatch 6/12 Skylake - X you can set that one to 4.5/4.6Ghz and you will not see heat issues.
