6700K and ASUS Z170 Deluxe suggestions

Hi,

I am quite new to overclocking CPUs since I am a gamer and CPU was never the bottleneck. While waiting for my 1080 Strixes to arrive, I have turned to CPU OCing.

I have ASUS Z170 Deluxe 6700K 32 GB of Corsair Vengeance LPX 2400, Corsair 1200AX and Intel 2500 Pro series 480 GB SSD.

I managed to get a stable OC of 4.7 GHz w/o Voltage but the submission to HWBot says this: Your system is not performing badly, but there are a few people with a Core i7 6700K running at a lower frequency and performing better.

XTU - karlisn - Core i7 6700K

Is there something really important I am missing that could boost my results with the same frequency?

Thanks in advance and hoping to hear some good ideas
