I am just saying you could run at lower CPU voltages if you were to reduce LLC because running at a high LLC makes your voltage drop under load regardless of chip set thus making it so you need a higher voltage to run things under load.

And with a lower LLC you will see more stable voltages underload.


Heres a little explanation of what Vdroop is if you don't understand to help you out a bit.

Low Vdroop setting = increased voltage under load.
High Vdroop setting = reduced voltage under load.

High Vdroop setting (52%) - with my Vdroop settings set to 52% my voltage under load went from 1.35 to 1.28 and thus I received a BSOD.

Low Vdroop setting (19%) - with my Vdroop set to 19% my voltage under load goes from 1.35 to around 1.32-1.36.

So mainly with a lower Vdroop you can preform more stable OCs, but always do a quick test run before you just ignore it just in case you huge spikes in voltage i.e. 1.425-1.45 because that can harm your CPU.

FYI if your wondering about the percentages with my motherboard I can adjust my settings by 3% increases or decreases and 0% = off for me while %100 = fully on.

Also here is an actual review site coming up with the same findings as I just explained in more depth. Yes it is a AMD board but the same concept applies.

But overall yes you may experience a small increased voltage underload, but overall it makes for a more stable OC in the end and it will make it so you can run at a overall lower voltage in your CPU voltage setting because you won't have to counter act the Vdroop voltage drops under load.
This is completely the opposite way around on sandybridge

low llc = 1.35v idle 1.295 load
high llc = 1.35v idle 1.312 load
extreme llc = 1.35v idle 1.38v load

Low llc = low level voltage input under load
high llc = high voltage level input under load to counteract vdroop
