The motherboard is very new a pro carbon series and maybe it just hates massive overclocks on AMD,But I will see if there is an update and If it still "unpredicable" I will can it and just run fans of the bios.Its winter here so as soon as it warms up 100 percent on all five fans 120s and a 140 will be the go anyway ,AMDs are not seen in the film Cool Runnings.
I have the MSI Gaming Pro Carbon X370, with a 1700 R7 @ 3.9ghz and G.Skill Trident Z 3200mhz ram running at full speed, so I dont think it hates big overclocks, I still dont have any problems, I never software overclock, its unreliable compared to bios overclocking, and in my opinion, harder and more confusing, not only that, it doesnt take effect until windows has finished booting and the software itself loads, Windows boot in itself is a good benchmark for overclocks.
