Asus M/B Offset and Adaptive Voltage mode: Voltage Spikes

[dmt_taran]

I've read tons of threads all over the internet with such a name (or close to it), but I've not found at least suitable answer or solution to this issue (exept for chit chats, "i dunno dude, I was just passing by" sort)

I have 8700K with maximus x hero system. CPU is capable of 4.8 GHz at 1.24V, 4.9 at 1.3, 5.0 at 1.355, 5.1-5.2 over 1.4V, uncore ~4.5GHz at every step, no AVX offset. Every mark, every clock step I've tested gradually last 4 months, and I'm 200% sure it Is stable at those clocks with voltage mentioned. In addition, I've used manual voltage and LLC6 for additional stability, IA lines are set to 0.01.

Target is 5.0GHz
The problem is - I can't get stable OC and voltage while using offset and adaptive. Unlike manual voltage, adaptive and offset makes max load voltage fluctuate at 0.05V range. So either I have unstable OC with 1.312-1.328V constant supply with spikes up to 1.36V, or I have stable OC, but with spikes up to 1.408-1.424V.
The problem becomes more complicated under heavy workloads (e.x. BF1). These spikes get more rapid - I could even say that 50% of time CPU gets more excessive voltage.

However, it's not enough to utilize stable OC with lowered voltage - for e.x., suggesting spikes go 50% of workload time and even more, I could lower voltage below stability point, achieving sweet spot between spikes and undervoltage - but it doesn't work, OC is not stable! :mad:

So what is it about? Why voltage is so unstable while using adaptive and offset? How can I solve this problem? Even if it cannot be fixed while under load, maybe there is some way to decrease these spikes, at least to 0.01V mark?

i know how iit all works its just the fact that using adaptive mode uses the cpus vid table and if u get to much volts on load u use a offset or lower load line . well tyes true but then u get under volts and whea error or over shoot by 0.060 or more ....... lots of people have same issue i dont need spikes from 1.32v to 1.41v thats not good lower load line a notch did that and yes it helped but now i get vdrop on load and whea error since i drop down to 1.312v when 1.32v i typed in its asus issue i have tried all the bioses to . soonas the cpu gets a heavy load she get spikes .

using manual vcore again ..

Well, I dunno, trying to tell guys that it helped me - I simply add -1 avx offset - no more spikes, rock solid 1.35V under any kind of load while using the adaptive.

As for 1:1 AVX scenario, yeah, u won't get rid of those 0.05v spikes

ok so if i under stand this correctly

go back to adaptive volts with these settings

multy =52
avx offset = - 1
adaptive mode = totaly adaptive volts =1.392 v
offset=auto ( 0 )
svid to = on
svid best case cinario
load line =6
ia/dc load line = 0.01

and i shouldnt get those 1.392v up to 1.430 v spikes witha avx offset of -1 witch i already use a -1 offset in manual mode right now ?

Yeah, only reduce LLC to level 5 and tune up target vCore if necessary
I’ve already figured that LLC6 does greater overshoot in adaptive than in manual

DMT,

Nice to hear that I wasn't the only one with this issue. I was only trying to get to 4.9GHZ and I can do it with full stability running manual vcore with 1.295V. Im talking about running AIDA64, Cinebench, Realbench, OCCT and Intel's burn test. Cant get stable in manual, go figure. Going to check out your link. Any advice for a newbie OC you got?

I am new to this forum, so first of all - hello to everybody.

I have been struggling with this for over two weeks now (since I switched to Strix Z370 after Z68) and having red what you are saying here correct me if I am wrong:
- you can never set lower Additional adaptive turbo voltage than what the CPU VID tables says at particular moment for a specific muli-ratio?
- what is the difference between adaptive with offset and offset alone mode? In adaptive you can limit the max Vcore despite the VID demand, and in only offset mode you are always going along the VID's table with that particular offset?

Looking forward to your thoughts...

I set my Strix Z370F adaptative 1.200, LLC to 5, 4.5ghz on 8700k, still getting overshots like 0.048, 1.248. Tried EVERYTHING, there is no way around it. Sometimes i think setting a manual voltage and let it be. There will be degradation over time with constante voltage, but at least it will suply the right amont of vcore...dont know whos to blame for it, Asus or Intel, as i've only used asus for my cpu...

Following what was said here already I think that LLC level has quite an impact on this.
To contribute, in my case (exact same board) I set AV=1.23V, offset= -0,01 and by LLC=4 and multiplier ratio 48 I get Vcore: min. 1.200V, max 1.246V, average 1.216V, so overshot is ca. 0.026.

I believe you missed a zero here...:D

LOL, edited! I've tried everything, always results in overshot...i think its 8th gen nature...

adaptive is broken allways over shoot by 0.30 -0.60 .... if u you use lessloadline cali then its still bad but tiny bit better but then you get under shoot on load and get a whea error . so you use a offset but then the offset doesnt work right and its still over shoots . asus needs to fix this . and the borked audio on the z 370 scrathcy , static , un balanced sound .

back to manual 5.2 gzh @ 1.392v

You guys must test your adaptive settings, and check if "aware adaptive" is on, if that is on, doesn't matter what you do the cpu will demand and MB will deliver. almost always overshoots.

But test the settings, for example: I have my adaptive set to 1.000 negative offset to 0.100 for a total of 0.900, it works in bios but in windows I have 1.16 - 1.18 under load and goes to 1.200 sometimes (just a spike) but there is no amps being drawn at 1.2 so it doesn't matter.

that is the settings I have tested my way too. in the beginning I had up to 1.43 volts with adaptive settings way lower. and it has nothing to do with LLC. it is just different quality parts for each board and settings being different for different quality silicon. that's why everyone has to test their way or you could destroy something.
