LLC Question

[KotOr]

Hello guys. i have question about LLC for Asus board i have M11 Apex + 9900KF. There are lots of topic where is recommended LLC5. But if i look at this page https://elmorlabs.com/index.php/2019-09-05/vrm-load-line-visualized/ Elmor use manual 1.2V and with LLC5 max voltage with overshoot (20mV) is 1.22V and with LLC6 overshoot (40mV) is 1.24V. And when i try OC my CPU all core 5@ with LLC 5 i need 1.29V so with overshoot i get 1.31V and with LLC 6 i need 1.23V and with overshoot i get 1.27V.

So could someone explain me please why is LLC 5 so recommended? Or if with my case is better to use LLC 6 ? Or am i missing something? Thank you

Here this video explain it well but in the most basic of terms it's to help combat Vdroop that can occur and provide some more stability when overclocking.

Thank you for the video.But this still doesn't answer my question.And i am sorry my english is not best so maybe i'm missing something to properly explain myself. I understand that higher LLC help you combat vdroop and at some level it's introduced overshoot. As buildzoid said " if you are not running some crazy voltage" it's fine to crank up LLC but he still recommend LLC 4-5. But lots of people recommend using just LLC 5 and lets say average voltage for 9900K-F is 1.3V and with info from Elmor lab. LLC5 still overshoot 20mv so in the end we have 1.32V so its still good.And if i use those overshoot numbers with LLC 5 i have at the end 1.31V and with LLC6 i have 1.27V . So for me looks like LLC6 is better and maybe even other would have better result with this. Because LLC6 has smaller vdroop and still acceptable overshoot ???  So i'm trying to understand why is LLC 5 so much recommended. because for me looks like LLC6 works better. I have done all testing so for me is just load my save profil and go. But i just want to know if i should use LLC 5 as everybody says or go for LLC 6 because for me as overclocking noob those numbers looks better ?

LLC 5 is recommended because LLC 6 will just over shoot the voltage past your vcore setting without offset.

 

So with LLC set to 5, it will prevent drooping on full loads.

without offset? so i have it like this Adaptiv with LLC 6 1.3V offset -0.080 and idle is 1.225-1.23V, non avx load 1.18V and avx 1.2V  and for LLC 5 1.3 offset -0.010 and idle 1.290V . adaptiv for me must be 1.3 if i set something diffrent then voltage is so weird

With adaptive and LLC at around 5-6 it will overshoot a tiny bit but due to adaptive mode if you run any artificial stress test it tends to rise up over the set maximum voltage giving you inaccurate results. This is why it's not recommend to use artifical stress tests when in adaptive, however programs like Cinebench is a real world stress test and not cause that large voltage rise.

 

If you can get away with a lower LLC go as low as possible while still maintaining stability, I personally don't go over LLC of around 5 but that of course depends on your board and CPU.
