How load line calibration actually works

Now I'm even more confused. I read Vcore with a digital multimeter off the capacitor bank on the back og the motherboard. There I get a HIGHER voltage reading than Vcore set in the bios under load with "turbo" LLC, while I get a LOWER reading when I set "high" LLC. Now I don't know what number to trust or what LLC I should choose.

Probably the most useful OCing video I've seen in 20 years...

can you do a short video about VR Vout?

Apologies for my lack of knowledge regarding the topic of voltage regulation and monitoring, I’m kinda new. Does CPUID HWMonitor report the VRM Controller voltage (Die sense) or the Super IO voltage? Or both?

So my 5 ghz OC is stable but when I play a game for approx 20 minutes, the game “dies”. I can immediately start the game back up but approximately 10 minutes later, it “dies” again. My LLC is set to 4. Will setting the LLC to 5 help or hurt with stabilizing the OC during gaming?

Tl dw?

Hey buildzoid, small question. When you're doing a video like this, where do you find your sources?(Like for example, where can I find the document that you're basing this on?)

Thanks a lot for this video! I was really confused with the LCC behavior before, for I was considering your Gamer Nexus' entry from 2 years ago.

I've been using VR VOUT to monitor voltage for a while, now, but I'm still a bit confused with WHAT I should expect as a sustainable, healthy VDROOP. Using both medium and high LLC with a Z390 Aorus Ultra mobo I get that 0.1 mV VDROOP and using turbo get 0.05 mV. Should I aim for a higher VDROOP then? For everyday oc'ing? Using AUTO I was getting overshoot (unecessary 1.4+ for 5.0-5.1 GHz i9-9900KS) but with MEDIUM-TURBO and manual VCORE settings that's not happening on heavy CPU gaming (emulator RPCS3, which I've found to be a GREAT strees testing tool lol) or Geekbench.

I don't have the guts or knowledge to use Prime95 tho

Thanks in advance for reading this and answering, if you may.

I just set my LLC setting to what gave me the closest to my VCORE set in BIOS and stress tested from there.

So is the video from 2 years ago wrong?

Wtf my llc settings are from lvl 1 to 6 what is a medium setting here? 3? and high would be 4 5 6? pls help

When it comes off load is where it spikes a bit and then comes down so your trying to compensate with LLC for excessive droop voltage and it will overshoot a bit if you look at your graphs while loading certain workload calculation. So the higher number settings you enter is good to compensate for droop but watch out with v-core plus this slight voltage spike overtime could cause some degradation for sure. But LLC can be your overclocking friend for stability. Been in the computer builds since the 90's. Great to see young guys like you in the field that's why I subscribed and would recommend others to do so as well and keep up the good work BUILDZOID!

Stop speaking. You are horrific at it.
Narrate to someone else.

You are freaking funny :D

But you say when you go extreme llc, the voltage regulation gets worse. Ok so what does that mean? It kind of sounds like you could get overshoot, and undershoot, by using the extreme setting. So in the end its the same because if they are protecting against vdroop, im willing to bet that the voltage is higher more than lower. So despite all this new understanding the end result is the same as the incorrect understanding.

Is super IO only a Intel thing? if SVI2 on Ryzen is actual VRM measurements then in HWInfo64 that number is accurate?

This video is just rambling and confusing. I don't want a 33 minute video on what load line calibration is, when its mostly waffle, wondering off on tangents ALL THE TIME. I just want a clear explanation, with some time line moments in the video. This could be a 5 minute video, with a quick apology of your old explanations, a quick diagram, and some factual points for clarity.

Skip in the video 20 minutes for the direct LLC breakdown and info.

How am I going to know that my ASUS board has this fix or not? What is the name of it, digi+ vrm?
My board is tuf gaming z490 WiFi

So it’s bad to adjust the ac/dc LL? We should only be adjusting the LL CAL “trim” on modern boards?

I'm more angry he called it "IxR" losses. It's I² x R losses If you're gonna be wrong, at least be wrong using correct math. sheesh.

Hi, Thank you for this tutorial. vVery Useful. I have recently built a computer based on the Asus Maximus 13 Hero + intel i9- 11900K. In the Bios menu, I have a setting named "Voltage Monitor" with two options, i.e. "Die Sense" or "Socket Sense" under Extreme Tweaker\DIGI+ VRM. Which one should give the most accurate Vcore reading in your opinion ?

Best regards

I always walk away smarter.

Well...Ummm...Yeah...Soo...Yeah... Thanks for the vid and info!!

i consider voltage spikes as overshoot

Maybe a stupid question but how much droop of the voltage is normal? I know that on intel systems the voltage goes up under load and with AMD Zen it goes down under load but is there a sort of number you need to focus on getting up or down? Thank you very much for the great content :)

I think you will need one more video talking about Load Lines... LOL.
It's "impossible" to talk about VRM, VID, VCore and load lines without talk about DC_LL and AC_LL.

"I was wrong," "and here's why I was wrong," "let me make drawings correcting what I was wrong about so you know the right information"

- absolute and utter Chad: Builzoid

Something sorely lacking in the tech space is being unable to directly state "I was wrong"

Thanks bildzoyd

Sooooo if I can't ask the VRM controller to spit out a voltage measurement because of analog vs binary then how can I command it to give me x amount of voltage?? 🧐

At least this must mean that when I ask for lets say 1.45V the controler just have to guess what I'm trying to say, right?

So you helped me understand how it works, but then said throw that out the window if you have an asus mobo lol. I have a Asus Z590 gaming wifi-e and an 11700k but now I don't know if I should use high LLC or extreme. If 1.3v is good for daily use then 1.4v with high llc should be 1.3v under heavy load? Or would it be better to just set it to 1.3v and extreme?

on OCCT I can't figure out which are the VRM controller or super IO, but Core 0-7 VID shows max spikes of 1.45-1.465V and lows of 0.66V so im guessing that is the super IO or the stock settings just let it get zapped?

ASRock, at least Extreme4 has it backwards. Level 1 is 0% and Level 4 is 100%. UEFI says Auto is Level 1/disabled. I set it to Level 2 and hopefully it's ok.

ASROCK has a F-STREAM utility. In the system tab, all voltages are displayed in real time . CPU input V., Vcore, DRAM V. ... . I have no idea where these voltages are read from. I hope that directly from the voltage regulator. (Z97 KILLER)

Does extreme hurt things?

Does this means I can skip touching LLC and increase vcore

you repeat yourself so much before starting a sentence, so much filler of words between actual information getting transmitted. You gotta commit when you start a sentence, something i guess we can all work on, but since youre producing videos this is something i would expect you to try to eliminate entirely.

Your videos have single handedly helped me understand, diagnose, optimize and straight up fix issues with my pc. Youre amazing man. 🤖

Had to run LLC medium on my Gigabyte motherboard just to have my 13900K stable at stock speeds.

Ну так в Итоге как правильно то????
на low или medium ставить???

So how loadline actually works and what actually Vdroop is? I didnt get it from video.What LL trim actually does? What connection it has to actual voltage, how it affects that??

its actually so easy when you know whats happening

when will make a how to under volt and LLC at the same time? seen some video done on 75950x3D or newer amd cpu i dont know if it safe?

If you set a negative PBO like -35 for a CPU like 7800x3D, is it safe changing the LLC setting from default?. I ask because, some people say to stabilize a large negative PBO offset it is necessary to manipulate the LLC setting.

You are the OC Sensei I've been searching for my entire life 😁

For someone who just wants to overclock, how do I use any of this information to know which llc to use with my system? I have a z690 msi meg ace and an i7 12700k with 32gb of ddr5. I know i can increase or decrease voltage using load line calibration, lite load settings, or a voltage offset, but i don't know how to decide which to change and how to optimize all three.

Thank you kid. I learned a lot. I build my own computers every ten years and now I am in my heavy learning process. The whole industry is depressing. I am still happily using my 9830k with a 980ti. EVGA is gone, processors video cards caught on fire. High prices.. It is really depressing. However, I see the potential in the 285 line in the future. The boards are at the start of the cycle so 285. What motherboard do you reccomend. I will overclock it 10% below the limit. I would like to game at 4k and upscale some old video and audio. Do you agree with me? Should I also buy cheap ram until they get to higher speeds? Secondly, 5090 all the way even if that is overpriced. Also, would two 5080's be technically faster? What ever happened to the non-mining cards Nvidia used to make? Why don't they all make those kind of standard? Finally, kid, don't get too upset over things. It's not good for you. You are really teaching dumb people like me. Thanks for your time. Be happy kid!🖖✌💟

Ik this is old, but your rant about how people come to conclusions on LLC based on software readings, like most people do, is wrong, but still 50% LLC was always best whether I knew it or not.
