BIOS Manual Voltage isn't fixed [luckely]

Hi everyone,

 

Last month i overclocked my 4770k.
After watching A TONS of tutorials/videos specifically for Haswell,
From multiple sources, i got the idea that if i set the VCore to manual on the Bios,
i wouldn't have had any of the power saving features because the voltage would've been fixed, no matter the load.

But after entering in windows,i see a different story.
Basically i've set the VCore to Manual 1.255v in the Bios and the 43 as core multiplier (40 in cache).
All Power savings features like C States are enabled.

Looking at both HWMonitor and AISuite 3 i see that the frequency ,voltages and watts vary greatly depending on the load like
it did before the overclock (changing from 800 to 4.3Ghz and from 0 to 1.28v depending on the load).
Yes, it goes up to 1.28 for some reason when rendering and yes, voltage is manual, not adaptive.
I guess it gets more juice when it detects avx or something.

Anyway,the question is,why am i still getting the power savings i had when the voltage was on Auto
even if i keep hearing in every single guide that Manual voltage remove power saving by having
a fixed voltage at anytime?

 

Note: no, i don't want to "Fix" the issue,i'm happy with it,i'd just like to understand what is going on.

 

Thanks in advance.

But the why every guide say that you loose all power savings with manual voltage if you then just need to enable C-States?

Why push the Adaptive voltage option for power savings if you can just use Manual and then enable C States?
