I've the multiplier locked at 42x on a i7-6700k

HWMonitor shows package frequency fixed at 4.2Ghz and multiplier fixed at 42, however CPU package average goes up and down but stays above 3.2Ghz all the time.

Is it correct? Why multiplier is stuck at 42x? I've disabled C/P states in clover and enabled KernelPm and Apple RTC in clover config

UPDATE: Actually, I've seen it rarely goes to 800Mhz, but there are no intermediary steps, just 4.2Ghz or 800Mhz

So I've tried to change some settings as per https://pikeralpha.wordpress.com/2014/05/26/major-breakthrough-for-power-management/ basically disabling those C states and also set the cpu in "eco" mode in windows' gigabyte easytune, now it seems the CPU goes down to an average of 2Ghz, could be that those settings helped?
