Voltage fluctuation while OCing using offset (too much Vdroop)

Hello guys,

I am currently overclocking using offset mode.I noticed that the voltage greatly changes depending on what I'm using.For example when I'm gaming it stays at 1.22/1.23V,if I run Prime 95 it goes down to 1.2V and if I run Cinebench it even drops to 1.8.
I thought that it was Vdroop but I don't understand why Cinebench droops more than Prime.
Is this normal or did I forgot to set something in the BIOS?
I have an i7 2600k with an ASUS P8Z68-V,the overclock is currently 4Ghz with a negative offset of 0.080(1.3V for 4Ghz seemed exagerated).Everything appears to be stable aside from the voltage fluctuation.
Other things that I changed:
Internal PLL Overvoltage:Disabled
Phase Control:Optimized
LLC:Regular 0%(because I'm using a negative offset)
I didn't touch anything else

When I read this I thought not enough LLC. Now I'm not overclocking guru but I don't know what you mean by 'I'm using a negative offset'. Because to my knowledge LLC is there to control voltage fluctuation regardless. However I could be wrong....

You are right,I don't want to use LLC with a Negative offset simply because I think that it's counter intuitive to add voltage with LLC when I'm using a negative offset because I want to use less voltage

To my knowledge LLC does not add any voltage. LLC refers to how aggressively the system attempts to maintain the set voltage. So this applies if you are under or over volting.

To anyone having a similar problem: I changed C states(C1E,C3,C6)from the BIOS from auto to enabled and now Vdroop is drastically reduced,now I can just keep LLC on Regular 0%

This makes no sense, but if it works who cares!

I have no idea why but now the voltage doesn't droop anymore when using Prime
