My GIGABYTE GA-Z68AP-D3 won't drop the voltage at idle

So my cheap GIGABYTE GA-Z68AP-D3(R2.0) from the Micro Center deal won't drop the voltage back down when idling if I overclock the CPU.
If I leave everything on Auto and simply raise the turbo frequencies, the board applies an automatic overvolt to 1.35V and that voltage won't drop when idle. The CPU frequency will drop to 1.6ghz, but the voltage stays at 1.35V. If I set the voltage to NORMAL and adjust the turbo frequencies the same thing happens and I get an automatic overvolt to 1.35V with no drop in voltage at idle. The same thing happens when I adjust the multi also.
I've tried a lot of combinations of settings and none seem to work. They all result in 1.35V or a fixed voltage if I fix the voltage. I can set the voltage to 1.2V and it stays there, but won't undervolt on idle. I can set the voltage to normal and use the dynamic overvolting and it sets the V to what I set it at but it won't undervolt at idle.
Is there anything I am missing here? I'd like to be able to get this chip to 4.5ghz under load, but idle at very low power. When I reset the board to default settings the chip drops to .8V on idle, but touch a single setting for turboboost and the board is at 1.35V.
