Did you try this without changing the AC and DC load lines... leave them on Auto - changing these only if necessary. Also, enable all c-states up to C6, disable speedSTEP and enable speedSHIFT in bios. Adaptive is working fine on my Max11E. NOt all that different from your Formula, and I'm using LLC6, 1.325V in bios - AVX loads droop to 1.279V.
Hey man thanks for the reply.
When I was dialing in my manual overclock I couldn't get it stable at a reasonable voltage until I set IA/DC loadlines to 0.01. Then I was able to get stability at a good voltage. In Raja's adaptive OC guide he suggests setting these to 0.01 as well. I did this on my 8700k adaptive 5Ghz OC as well.
I could try setting them to auto again but if last time was anything to go by, it will want more voltage and I'm already hitting peak individual core temps of 92-95C in 1 hour stress tests of RealBench or AIDA64. So I don't really want to add much more voltage when I'm stable at 1.27V load with these settings.
All C states should have been enabled with my adaptive settings, I didn't disable or enable them individually, there is just one setting that say "C-States" that you can either enable or disable. That's all I did regarding C-states.
If I disable speedstep and speed shift, will that not prevent the CPU from downclocking/volting when idle on balanced windows power plan? Or will it just prevent the CPU from downclocking and still enable to voltage to drop at idle? Sorry for not fully understanding.
The part that I'm most confused about is why the LLC behavior would be different between manual and adaptive, because that seems to be what's preventing me from achieving stability in adaptive mode. 😕
actually that's : disable STEP and enable SHIFT as I posted.
Shamino laid this out for you - follow his recommendations. As with any recent architecture, Adaptive only applies to multipliers higher than the stock max turbo multi, and then it can only ADD(itional) turbo voltage to the VID at that multiplier.
welcome to adaptive voltage
understand the criteria for adaptive voltage to take effect :
per intel design:
1) adaptive voltage only takes effect at ratios > max single core boost ratio which is 50x in 9900ks case (so if you set 1.5v at 50x for eg, it gets ignored till you go up to 51x)
2) any volt set below the cpu's default vid gets ignored (eg setting 51x ratio with 1.1v when cpu's vid is 1.25v at 50x will get ignored)
on client you still have AC/DC loadline to manipulate to undervolt proc to a certain extent (you have no room to undervolt when AC/DC LL is already at minimum)
to undervolt further you will have to rely on VRM Loadline.
so in view of the above:
comparing a different cpu on different boards does not shed much information, number 1 (specially with 8700k when you will be way above the single core boost of 47x making adaptive easier to use)
number 2 : the volt sensing is different on maximus Xi than on other boards , its sensing on-die volt compared to traditional off-die sense
in your case the straightforward and very logical way to run adaptive is to run the minimum LLC that is stable at 5g (since any v setting gets ignored by proc till it goes to 51x)
EVEN IF YOU COULD run a vid lower and a higher LLC to match, it typically runs cooler with a higher vid and a lower LLC. (you can verify this just by being on manual mode)
Hi, thanks for your reply
Sorry but I don't fully understand this part. I know that LLC7 is the minimum stable LLC for manual mode, I've tried LLC6 and increased target voltage to compensate but it just won't be stable. I spent a few hours trying today. Someone on OCN said the same thing about lower LLC having better transient response and requiring a lower VMIN but I can't seem to replicate that. Even at the same voltage under load with LLC6 it's not stable, where as LLC7 is.
So knowing that LLC7 appears to be the most stable for my CPU in manual mode, what should I do for adaptive mode? When I run LLC7 in adaptive mode I get overshoot at idle and at most, only a very small drop in voltage under load (from target 1.33V to 1.32V). When I run LLC6 it idles at target voltage and drops about the right amount under load but is unstable. The only thing I haven't tried is maintaining LLC7 in adaptive mode and lowering the voltage target. Is that worth trying?
Thanks for your advice.
I know that LLC7 is the minimum stable LLC for manual mode, I've tried LLC6 and increased target voltage to compensate but it just won't be stable.
=> you mean adaptive right? and at 50x ratio right? now wouldnt that still mean that increasing target voltage does nothing becos its not > 50x ratio and hence gets ignored? so bascially the vid doesnt change becos criteria 2 is not fulfilled.
The only thing I haven't tried is maintaining LLC7 in adaptive mode and lowering the voltage target. Is that worth trying?
=> that still wouldnt work becos criteria 2 is not fulfilled. your target gets ignored
your last paragraph is basically saying level 7 is too shallow and level 6 is too steep.
=> you want just the right amount of v with adaptive , only way is to do this:
remain level 6 50x adaptive auto.
manually tweak ac/dc ll. 0.01/0.01 value is where you're at and u are unstable
increase this to 0.03/0.03, etc etc till you get what you need with VRM LLC 6
