1.5v at 5 Ghz and .784v at 1.4 Ghz sounds like it's a normal power saving state. (You don't need or want 1.5 volts going to any chip that doesn't need it.)

Maintaining full speed and voltage while at idle, is like putting your car in park at a stop light and flooring the accelerator whilst listening to the motor bounce off the rev limiter...all while you sit and wait for the light to turn green.

However, if you really want full speed and power all the time, (and most likely a shortened CPU lifespan) you can just disable "cool n quiet" in the BIOS and disable all C states.

(Cool n Quiet is an AMD feature. 1.5 volts is high for an AMD chip and way high for a sandy/ivy bridge CPU.)

Here's an example of my chip. However, since I'm running an Intel CPU, the Vcore stays the same.

im sorry i forgot to mention its going to 0.784 during gaming and load

Could it be throttling back due to overheating?

temps on a single component have never been over 55c

I would verify that with at least two different sources. I have found many of the software programs to be hit-or-miss with different cpu/mb combos.

i had 3 open and they were all reading 23c and someone said my mobo must be bad bc those temps arent possible
