Overclocking on the Z270 platform is pretty much like it is on Z170. Because of time restrictions we will only be doing basic overclocking here. There are a few ways to overclock with this motherboard. First you can simply press the OC button on the motherboard. This overclocked our Core i7-7700K from 4.2 GHz up to 4.7 GHz.
You also perform the same overclock by using the EasyTune software. You can select OC on the main screen, or even select AutoTuning.
Finally we can go into the BIOS and either manually overclock or select one of the CPU Upgrade options. Manually overclocking we set our CPU frequency to 49 and our CPU core voltage to 1.4V to achieve a stable overclock of 4.9 GHz. We were able to boot at 5.0 GHz, but the system was not stable.
