4770k Voltage Problems Seeking Answers

[Titan of Canine]

I can easily get a 4.3 Ghz OC on my cpu with my h80i and Mpower Max z87, but I do not want to use a fixed voltage. I would like my cpu clock speed and voltage to decrease when idle and increase when under load. I was able to make my cpu ratio decrease when idle by setting the cpu ratio to 43 and setting it to dynamic in BIOS.
My problem is with the voltage. I set my voltage to my desired 1.230 volts and set it to adaptive, along with my offset mode to minus and auto(Because wouldnt setting the voltage offset to minus lower it, not increase it?). With these settings, both the multiplier and voltage lower, but when I run a stress test, the voltage goes over 1.230 volts at times, sometimes even reaching 1.3 volts.
I have seen this happen on default also, with no overclocking, when the multiplier goes to its 3.9 Ghz boost, the voltage boosts up to 1.150 volts on light tasks, but when doing an extreme stress test, it may go even higher to 1.219 volts according to cpuz (1.245 volts according to multi meter). Is this normal because of IEST?
On my 4.3 Ghz overclock, I tried setting the voltage to override and the offset to minus and then gave the offset a value, thinking that the offset will be the the amount of voltage lowered when idle, but then the voltage is basically 1.230 volts (minus) the offset voltage I gave at all times, not only when idle. It does not increase to 1.230 when i run a stress test.

My main question is if anyone with more experience in clickbios 4 could tell me if there is a way to lower voltages when idle without making it go over the given value when under load?(or set a maximum voltage). Is this happening because if IEST, or is it some motherboard setttings?

Specs:
Motherboard: Msi z87 Mpower Max
CPU: 4770k
GPU: an old 9500gt for now
RAM:8gb (2x4) 1600 mhz Corsair Vengeance
PSU:Corsair HX 850
Cooler:Corsair h80i

you need to use line load calibration to help regulate the voltage. each setting is different and you will have to check each one to see which one keeps your voltage where you want it. you "should" be seeing a higher voltage when at idle and a lower voltage when under a load. I've never worried too much about the idle voltage just as long as it isn't too high, its really the load voltage that matters as thats when heat is building up. i don't know what the voltages for haswell or ivy are, I know sandy bridge stuff. hope that helps.

What you are seeing is perfectly normal and is the way that Intel designed the Haswell platform. When set to Adaptive, voltage will increase above the setpoint during periods of high load. The only way around this is to use "Override" mode during stress testing, but that will hold a constant voltage, even when under light loads, like idle conditions. When not stress testing, use Adaptive mode.

For maximum voltage flexibility, also be sure that your Power Option in Windows is set to "Balanced", otherwise the voltages will stay at needlessly high levels all of the time.

You could lower the umm..VRIN

So the only way to fix this is to set my voltage to fixed? There is not a way to lower voltages when idle without making it go over the given value when under load?

Unfortunately, no. However, the voltage increase "under load" depends greatly on the "load". When stress testing, the voltage increase can be significant. However, during gaming and normal day to day activities, I think that you'll find the increase to be minimal.
