Gigabyte Z87X-UD3H with i5-4670K voltage help

[ReaperSrtruck]

Been playing around with overclocking my CPU to see what is can do. 3.8 is the stock boost at 1.18 volts. With a multiplier of 41 my voltage will remain at 1.18. When I bump up to a 42 multiplier, CoreTemp is telling me that my VID is 1.38. I know this is overkill and not right. Why is the voltage rising that much. I was hoping to get a 4.5 overclock.

set the voltage yourself (is it in auto?), just research the max safe voltage first

If your voltage is that much, try manually lowering the voltage in your BIOS until the PC wont completely boot, make sure you only put the voltage down by around 0.01 volts each time and when it will not successfully boot raise the voltage again by 0.01 volts and see if it boots. If it boots then that is the lowest voltage it will go on that multiplier and clock speed.

I've tried going back into the bios and setting the slide bar back to 1.18 volts. But CoreTemp reads 1.38 still. This mobo is driving me crazy. There is no Manual setting for vCore, only Auto and Normal. Looking to keep voltage below a max of 1.275 and keep cpu frequency and voltage down when idle also.
