i've just updated the bios on the Strix Z370-F (ver 0616) and all OC settings (even the saved profiles!) was resetted. Now i've noticed that the cpu won't downclock anymore when he is in low load/idle. Before the update my i7 8700k downclock from 4700mhz to 800mhz (i've setted vcore adaptive).
What's wrong? I missed some settings in BIOS? Is a bug in the new BIOS?
