CPU Load Line Calibration Levels on ASUS Board

[Neruu]

I have a ryzen 1700 and Asus X370-F Strix Motherboard
so when I tried to overclock the 1700 to 3.7ghz, i set my voltage to 1.25v on the bios but i got vdroop during load (handbrake encoding)
then i tried to set my LLC to level 3 and CPU current capability to 120%, but it still crashed
next, i set my LLC to level 5, and CPU current capability to 130% and now it's stable (stressed with AIDA64)

my only concern is,
i've read on http://www.tomshardware.com/reviews/overclocking-amd-ryzen,5011-2.html that LLC could cause overvolting to ur cpu
but during all my test, even when I set my LLC to level 5, the reading on my vcore never went past 1.25v (i use cpu-z, aida64, and hwinfo)
is it my reading that's wrong? or does even if you increase LLC, you wouldn't get past your maximum voltage setting in the BIOS?

temperature is quite nice, around 83-85 (yeah, i'm still on stock cooler :/ ), but I just didn't want to overvolt my cpu without me knowing

any help would be appreciated, thanks

LLC is working by setting the voltage higher than required so when it drops under load it will still remain at the required level.
the actual effect depends on many thing, so if your voltage readings under load still display acceptable values and the temps are fine - everything is OK.
there are also cases when changing LLC does nothing - BIOS bugs etc.

thanks, that assures me a bit

it's just that this LLC setting is kinda too ideal (maybe i just happen to get good motherboard?) where setting it on lvl 5 makes my idle and load voltage exactly the same as what I set on the bios given my readings is right, like literally 0% vdroop

that is impossible. any board will drop a bit.
anyway, setting LLC to extreme values is not recommended.

thanks, the videos really helps now i understand why my software readings gives little to no vdroop during load
now so i need to find the perfect balance between the voltage for my system to actually boot and the llc settings to compensate vdroop while still giving room for the peak voltage so i don't fry my cpu

do u think it would be better to have the lowest voltage possible with higher llc settings, or higher voltage with lowest llc settings?

IMO, the LLC should be on medium level with lowest stable voltage.
