I want to do a bclk overclock on my Skylake i5-6600 (non-k), but I'm not sure which BIOS version to download for GA-Z170-HD3. Should I just get the latest beta F22f, or get an older version like F6e, which is the version I've seen on the overclocking.guide site. I know at some point they disabled the ability to change the bclk, but I'm not sure if that applies to the beta bios.

Also, if the c-states are disabled, will it make my monthly power bills go up by a lot? I only game maybe 10% of the time. The rest of the time I leave my computer idle or do simple web browsing.
