Overclocking on this motherboard can be done in a few different ways. The easiest would be to run the 5-way Optimization in the Ai Suite III software. After running it, it gave us a 4.9 GHz overclock, which is very impressive, but temperatures were a little high for us.
The next way to overclock is the EZ Tuning Wizard in the BIOS. It asks you a few different questions about your setup and does its thing.
After running the wizard we came to an overclock of 4.63 GHz. This was with the multiplier set to 45 and the BCLK set to 103 MHz.
Finally of course you can fine-tune things manually in the BIOS. Because of our limited time with this board (less than a week), we were not able to really get into Skylake overclocking as much as we would have liked. Expect a follow up article on that specifically. Using the same process we did with Haswell we were able to bring our Core i7-6700K up from 4.0 GHz to 4.7 GHz. This was achieved by simply setting the multiplier to 47 and changing our CPU core voltage to 1.4V. This is a 100% stable overclock as it passed all of our benchmark tests as well as a stress and temperature test.
