Overclocking
This page is more interesting to the enthusiast who wants to push the system. We swap out to some G.Skill DDR4-3600 memory and see how high it can go with a toasty 1.45V applied. The CPU, too, is overvolted, to 1.35V, while we also see how good the power regulation is in an indirect way by measuring the best stable speed at 1.1V.
The trio of results aren't definitive, of course, but the Z170S Sabertooth does have a little extra in the tank at the high end.
