I need help with Adaptive/Offset voltage

Hello.i have 8700k and maximus x hero.I run stable 4.8 @ 1.265 with llc 6.

Because i have the pc all time working,i want undervolt on idle.What is the best choise,offset or adaptive?
Also what setting must check?I know that i have to enable svid to work offset or adaptive.

I would say adaptive, that is what I am using right now. This guide should help you set it up: http://edgeup.asus.com/2017/kaby-lake-overclocking-guide/3/?_ga=2.185832041.1973363672.1518950532-88...

Also have a look at my thread if you run into any issues: https://rog.asus.com/forum/showthread.php?101944-Having-trouble-moving-from-Manual-Voltage-to-Adapti...

When on manual voltage I used the exact same frequency, voltage and LLC settings as you, however interestingly I was able to reduce my LLC to level 4 when using adaptive voltage, which reduced my load voltage to around 1.232V and I am stable. My temps dropped quite a bit as a result.

I did some test and I am confused.

My settings
Best case scenario CPU svid behaviour
Offset sign +
Additional turbo mode CPU core voltage 1.265
Offset voltage auto.
LLC lvl5.

On aida64 and realbench I see max 1.296 vcore

So I tried offset sign - with the same results.
With 1.2 addition turbo mode CPU core voltage and I see 1.280 vcore.
With LLC lvl4 I had blue screen even with 1.3 addition turbo mode CPU core voltage.

When I am on manual 1.265 I am stable in all tests.Any help??

Hello AndrewkROG

Let's see if we can get the voltage close to what you're setting.

In the bios - CPU Power Management

Set:

IA AC Load Line .01
IA DC Load Line .01

F10 and Enter

If it still goes to 1.296v, enter a negative offset of -0.030v, this should put the voltage at 1.265v or very close to it.

Ok i had to set the negative offset.

I am having black screens on realbench.I tried with no oc and again the same.Some software that i install maybe giving errors to realbench.
Stable on aida64 and prime95 26.6.


Thanks for your help!!

Just an FYI that setting SVID to “best case scenario” sets these IA AC load line resistances automatically internally as confirmed by Asus.

Just wanted to mention it in case anyone was wondering. **

adaptive is still broken on asus x hero latest bios . 5 ghz 1.36v total adaptive volts . load line =6 i get over shoot up to 1.402 v in some games ( bf1 ) fo rslight second .....
well why dont you try load line 5 or 4 ? cause if i go to level 5 my volts drop below 1.36v and get under shoot and a whea error hope they fix it ...

Yeah, i'm not messing with Adaptive again. 1.5v is too scary for me (nope, that issue still isn't fixed with latest BIOS)

i have fixed my adaptive volts - spikes 100 % and have posted how and what i did or should i say discovered the work around

load line level 6
ia/dc load line =0.01
svid best case
cpu power limits maxed

now say you set adaptive to 1.3v when u play a game or ap pthat uses avx you will get a 0.036v spike or more 1.3v + 0.036 v = 1.36v or more . some times close to 1.4v
n ow u can lower load line calibration but it doesnt help what i have found that solved all my adaptive 5.0 ghz over clock volt spikes was to set a
- 1 avx offset

why ? do that cause when you use a avx offset of - 1 you only get a spike of 0.016 v vs 0.036 v + with out avx offset -1 1.3v + 0.016v spike = 1.316v
using load line level 6 that is

im currently @ 5.1 ghz with avx offset - 1 ( 5.0 ghz on avx loads ) @ 1.36v adaptive with power saving and c states enabled i get a max volt spike to 1.376v ( 0.016v spike )
witch i can live with thats with in normal i can sleep at night knowing adaptive mode is working fine .

test it out your self 🙂 hope this helps

It's not possible to lock in adaptive completely. Nothing is broken, it's just down to how Intel implements things. You can alway use manual vcore if this bothers you.
