Gigabyte Z790 Aorus Elite AX voltage regulation and LLC testing

[@BillyONeal]

I love the perfect not camera needed oscilloscope shots 🎉

[@yikyik148]

Great video 👍 , I have Z790m aorus elite ax & 13700K , gaming temperature AVG 70° ~ I'm thinking of making some settings tweaks and your video was a great reference

[@joseperez-ig5yu]

Great video BZ! I find that there are so many nuances when dealing with the load line calibration! But it seems that you really get a kick out of it.

[@mrrobot6137]

Nice helpful video as I got myself one of these with an i7 13700k. Been running it on llc low since the start and it serves me well even If I can't go above 7200mts with my ram, which isn't really bad tbh.

[@nXqd]

you have the same motherboard or different. i have z790 ud ac, stock settings and OC it needs turbo to be stable.

[@braidedwire]

Any chance for a step by step 13th gen undervolting guide?

[@Snuggis]

Love these videoes! Gonna use your findings and see what I can do with this board at some point. Decided to go for the 13900K a short while ago, and this was the only motherboard I felt looked kinda decent without costing about as much as the CPU itself.

[@subgx0079]

Learnt a lot ,never choose ultra loadline on daily use.

[@subgx0079]

Wanna ask an old question,because i am first time to use Aorus mobo,why most of you choose Fixed vcore mode?Some times when i choose this,in windows i see vcore reading from CPU is different than my settings,only when adaptive or override it can be correctly applied.What is the purpose of different Vcore votage mode?Thx.

[@xBINARYGODx]

Wow, its a Giga board and low or medium is the best LLC - what a shock =-P =-)

[@EddieGD21]

Given the benefit of hindsight, you nailed or the key points Greg. I respect your intuitiveness. I considered that the real measure of intelligence. I just recently discovered your channel and I’m enjoying your fix or flop videos and their educational value. I have built eight PCs (both Intel and AMD) since the late 90’s and have luckily never faced those kinds of issues. However, one day my luck will undoubtedly run out. Btw, I’m gathering as much info as possible because I’m still struggling on whether to go Zen4 or Raptor. I don’t think I’m alone. I really only stress my systems when gaming, so productivity performance is less important. I wonder what advice you’d give. Cheers!

[@WillVerduzco]

Incredibly useful video, given that the vast majority of us will never hook up a scope to see what's ACTUALLY going on with our voltage rails on anything even resembling a microsecond time scale. Buildzoid: Could you please do follow-up video(s) on the Z790 Master and the Z790i Edge if you have the time? I've got the former (which I suspect is similar in LLC performance to the Elite in this vid) but am thinking of jumping ship to the latter given that it might be better at mem OC. And if I do, I'd love to have data on LLC levels.

[@MMGuy]

Uhh, what is this "biscuits: out of range" in the bios? On the right, where it shows the voltages.

[@BillyONeal]

Mmmmmmmmm biscuits

[@TrueRegulators]

It's a silicon quality prediction feature similar to Asus SP rating. Only works tho when cpu is running at auto, not static clocks

[@fracturedlife1393]

Gigabyte had enough of everyone randomly naming things different and went abstract.

[@luks6436]

Yeah but its wierd , I lost 2.xxx by nothing. I hat 92.xxx at Day 1 now at Day 30 Only 90 xxxx Without e cores over 95.xxx

[@GuidoDePalma]

[@polishKGB]

Please do an optimization guild on this board with a 13700k I beg of you. No good reliable information on this board or it's bios settings. I haven't bought in for 5 gen now and I'm lost in the bios

[@GuidoDePalma]

there should be some guide from Skatterbencher

[@Syntax_-_Error]

Would have loved to see the gigabyte override voltage mode also, and how it works on Z790. But great video anyways, as always!

[@mackannm2439]

Hi Buildzoid. I’m basically wondering how you go about correctly adjusting the AC Loadline and DC Loadline according to the Vcore Loadline Calibration (LLC). I’ve watched/listened to your videos a couple of times and tried reading about the subject. But I’m not sure I completely understand it. I have a gigabyte z790 aorus elite x wifi7 with a 13700k. I would like to use the medium LLC but don’t exactly know how to go about calculating the AC/DC values.

[@YGadgETech]

Hey man thanks for the video , planning to build a system with apex encore 14900ks and 8400mhz g skill ram do I need to change the AC/DC settings or just leave it in auto? If I’ll just put the correct Intel power limits and svid behavior to trained or best case scenario and cou load line calibration to level 4 my system will work without crashes and instabilities?

[@sxj016]

Buildzoid: Would you please use that Aorus Elite AX and do a technical analysis of what the "auto overclocking" features are actually doing when measured by your advanced tools? What is Gigabyte doing to get overclocks with their bios?

[@zxcv4815]

amazing video thank you

[@CarnivoryHODL]

Still planning on reviewing the Gigabyte B650M Elite AX?

[@sxj016]

What was the final settings that worked? I'm buying the same mobo and want a good starting point.

[@soundspark]

My Gigabyte Z690 UD AX DDR4 must be set to LLC Medium to run stable at stock speeds.

[@milchkopf3881]

will there be a budget tachyon at some point?

[@N0rth0M-1]

the tachyon already kinda is the cheapest package for max performance, compared to stuff like the apex or dark kingpin

[@politicallyincorrect633]

How can I find out he LLC impedance table for my Z790 Asrock Steal legend mobo?

[@happiness_in_islam]

hello sir, Thank you for the great hard work you do and sorry to bother you, I'm planning to build a pc and I'm trying to find a video on your channel for a recommnended ram's for Gigabyte Z790 Aorus Elite AX ( since it's cheaper mobo and seems good one ) but i couldn't find it, i hope you can guide me for 2X16 ram with 13700k and a good mobo if the aorus not that great.

[@doctor_who1]

i have a 13900K with the GB Aorus Elite AX Z790 - and i'm struggling to figure out what LLC to set it crashes whenever i deviate from stock clock. i am trying to overclock it a little but not push it to the extreme. which LLC do i use? normal/low/medium/high ? thanks (BTW yes i'm watching the entire video as i type, to try to get some understanding)

[@reiener]

Hello, so what do I set now for a 13900K with enabled E-cores if I have set 2 cores at 6GHz? "middle" and "1.4V"? And why have you set the max and min ring cores to 42, is that the standard setting or does it run more stable like that? and is it better to set a fixed vcore value or adaptive

[@newfahlstrom]

13:32 : "you are wondering how I know what LLC corresponds to which voltage to get roughly the same average voltage, it's because I pretest everything (to have the voltages matching up the average voltages)" Can someone explain me please how to do this? I really fail to understand how to determine those vcore values...

[@markm75]

is there still any benefit to adaptive or offset for the voltage vcore setting to save energy and idle at lower volts?

[@abzaman77]

BTW BZ, does this board have a vr vout sensor?

[@Chinhnguyen0497]

Hi, please answer my question. Im using r5 3600 b450 tomahawk max bios version 7C02v3B. my llc option is 8 and vol drop is very little, i oc to 4.1 ccx1, 4.075 ccx2 set cpu vol at 1.35 but when i run test cb15 the voldrop is only about 1.336-1,340. is this normal? can i use it everyday? and above llc 5 there is no vol drop at all

[@stefanradunovic8318]

I don’t even use llc on my z790 tachyon. I have not even used on my msi edge either. 13900k 5.7 4.5 at 1.32 86c r23 42600k score

[@techluvin7691]

How about on auto voltage. How does it react?

[@Profetorum]

Can someone please explain to me what's the impact of the AC Loadline setting? I'm confused, it feels like another way of describing the LLC. Or to be more precise, it sounds to me like an extra voltage offset the vrm gives over the DC, like...putting a lower ACLL you can basically set it up to have an extra negative offset when under load? I'm on this same exact board, on low llc. Kind of confused

[@Jagerbomber2468]

What's the best way to test if you have a good LLC for your clock without an oscilloscope? On my 11700k, I'm at 5.0 @ 1.4v LLC5 on ASUS z590 Strix. LLC4 crashes. So I'm assuming to get LLC4, I would need to up to 1.43-1.45? I'm just kinda curious how to find optimal voltages outside of an oscilloscope if monitoring tools can not measure.

[@OCDyno]

You run a stress test (I prefer using ycruncher since it has wild load fluctuations) and you match load vcore, Im not sure if your strix has any accurate vcore monitoring (VRVOUT/Die sense) though

Nice reviews. I have a question. I have a z790 aero g. Idle voltage is 1.223V load is 1.272V LLC is set to Med. Voltage Mode is set to adaptive, Normal -0.11V. Idle and load Voltage have a Delta of 0,051V. Should i set the LLC lower or increasing the Offset ?

But so hard to follow, and please make like conclusion on video, and some pauses when you speak. I realy like your videos, but try to make like short pause after finishing sentence and stuff like that. NHF, love your work!!!

[@theodanielwollff]

So GB has the LLC backwards here. Extreme has the biggest drops instead of the lowest. Who named this stuff ????

[@ActuallyHardcoreOverclocking]

Ultra Extreme has close to 0 Vdroop. It has piles of undershoot. Level 8 on ASUS is the same as Gigabyte's Ultra Extreme.

[@facegamefps6725]

@@ActuallyHardcoreOverclockingultra extreme has drop. If you set 6.0 on 13900k at 1.36 it will drop r23 1.33 so it has drop

[@Kyori0]

@@facegamefps6725 we're talking instant drops which you can not measure without an oscilloscope at high refresh rate

[@facegamefps6725]

@@Kyori0 I care less about instant drop. I care about stability

[@Kyori0]

@@facegamefps6725 That instant drop is the thing which can cause crash/BSOD, so to minimize that instant drop you have to use Low/Medium/High LLC. Because when going above High LLC there is much more of instant drop. To compensate the average VCore drop from lower LLCs you need to raise your VCore, so it would have the needed voltage under the high load. (high voltage while idle simply does not matter)
