Overclocking on the Intel Z170 platform is pretty easy. The easiest way to overclock would be up simply change the frequency divider in the BIOS. To achieve the best overclock we try to stay with the timings that the XMP profile recommends, but we will loosen or tighten timings to get the best overclock possible.
The XMP profile puts this kit at 3000 MHz. In the BIOS I started moving up the frequency divider. By moving the voltage up to 1.4V I was able to get the kit up to 3200 MHz with the exact same timings of 15-17-17-35! Not bad at all!
