Hi there,
in this thread i want to ask some things about EVGA's specific LLC-settings (edit: for the EVGA z390 Dark).
While i wait on the rest of my hardware I've spent weeks on grinding through articles and videos to understand how Vdroop and LoadLineCalibration actually work. I think I reached a point at which i start to understand a bid more than the typical phrases, which also led to frustration as i realized how distorting and misleading a lot of videos and articles from big Youtubers and official Wiki-site are; at least for a layman like me. I read some posts from Delirious and those are clearly in the category "helpful", since he seems to have run into similar problems with understanding the settings as i do. So i quess this forum is the right place to ask my questions.
-----------------------------------------------------------------------------------------------------------------------------------------------------
1) Vdroop settings are made in percentages. As i understand there is a "natural" vdroop already implemented in the power specifications of the systems in order to save power, stay within TDP specifications and have better load transients (even though the last reason is often overly exaggerated as its main purpose.)
So i just want to make sure when EVGA states "-75% vdroop" that it really refers to the inherent existing vdroop as basis for a change of 75%. Is that correct?
In other words: With no LLC ("0% to vdroop"), there is still a vdroop, right? So the EVGA settings are not refering to some absolute values that simply change the voltages under load, but to a percentage change of the existing drooping, which in turn changes voltages in correspondance to current load. Is that correct?
2) The next one is simple:
"-X% vdroop" would decrease the vdroop effectively letting the voltage drop (that corresponds to the current load) be smaller. Hence it allows to aim for higher voltages under load. "+X% vdroop" on the other hand should make the vdroop stronger. Hence letting the voltages under load drop even lower. Im quite sure after reading some posts on the forums that this is correct, so a simple yes is enough.
3) I also read on the forums that the LLC-settings even apply voltages to idle state. At that point im not sure if i have understood LLC and Vdroop completely or if i misunderstood the posts. So my question splits into two different ones.
a) If you change the load-lines, shouldnt the
voltage changes at idle be a lot smaller than the
changes to voltages at load?
I mean calibrating the load-line would not be a "parallel shifting" of the line, but a change of the "steepnes" of the curve, correct?

b) If the upper one is correct, then the changes to voltages at idle should actually not be very high, despite some posts i've read.
So is there something different in EVGA's LLC settings than in others manufacturer's settings or do i still have not completely understood how LLC and Vdroop works?

Many thanks in advance for any helpful responses!
