I have an kaby lake i7 7700k processor in a gigabyte z170 chipset motherboard. I attempted overclocking, but my temps were too high and im too much of a noob at this to tinker with it any more, so i reset the mobo to (optimized defaults) my problem is, after all of this its only boosting to 4.4 gigahertz when it was reaching 4.5 before at stable temps. What do?
