I have a i5-6600K cpu and Z270-HD3 mobo,bios at f8...At advanced frequency settings menu I can not change the bclk frequency, multiplier and other stuff. All set at Auto. But with Gigabyte easy tune tool can set all these settings within Windows. Is it normal with this board? Easy Tune tool sets the parameters and restarts for example dram and cpu but I can not set them from BIOS directly. All set at AUTO, does not change???

This is my first time with Gigabyte boards...Anybody please respond about this...
