Not with a out of box Gigabyte Z270 HD3P. I am highly disappointed: not even the BCLK can be adjusted, it is locked totally :'( So board goes back to seller... Next ASRock...

As far as I know the codes to lock the BCLK of the non-K Kaby Lakes have changed to the past codes of the Skylakes. However Gigabyte just answered to my question if the non-K KabyLakes could be overclocked on a GA-Z270-HD3P just with: “Hello, The board allow to adjust BCLK with non-K CPU. †I will receive that board early next week with a G4560 (the i5 7400 was out of stock) and will test it If that fails -I have a feeling based on the quality of the answer it will-I will try a ASRock Z270 with Hyper BCLK Engine II and test that and post results here.
