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. Keeping the same timings and voltage I was able to get this kit up to 3200 MHz easily. I next moved up to 3333 MHz, no issues there either. On the next step up the system became unstable. Not bad getting an extra 333 MHz out of this kit without having to change timings or voltage!
