    Setting Adaptive / Offset Voltage on i7-8086K on ASUS ROG Maximus X Hero (WiFi AC)

    Asus ROG Maximus X - i7-8086K 5.2GHz Adaptive Voltage Settings

    Adaptive Voltage:

    Attempting to Enable Adaptive Voltage to prolong CPU life by limiting damage due to Electromigration (high currents causing short or open-circuits) or Negative Bias Temperature Instability (NBTI) which is what causes transistors to degrade over time. They become more difficult to turn on, slower to respond and become more resistive to current as they age. NBTI is worsened by high temperatures and voltages which can be produced when overclocking.

    Adaptive voltage allows lower voltages and less current flow in CPU when not under load to minimize effects of electromigration and NBTI.

    Adaptive Voltage settings require SVID to be enabled in BIOS to allow Vcore and current draw to be lowered.

    UEFI "BIOS" v1901 Adaptive Voltage Settings:

    Save Settings to Asus Overclocking Profile and name profile appropriately: Ex: AdaptVc5.2Ghz

    Save Changes and Reset

    In Windows: Run: powercfg.cpl

    - Select Power Saver Power Plan


    First screenshot is under 'no load' conditions with low Vc and low CPU speed.

    Second screenshot is under load conditions using IntelBurnTestv2. Note that the Vc=1.360V is higher than specified in UEFI settings. CPU is at 5.0Ghz because Intel Burn Test V2 was running an AVX test at the time so the AVX negative offset=2 lowered the CPU speed from 5.2 to 5.0GHz.

    Adaptive seems broken and provides way too much voltage at times. Spikes to 1.5v even while idle in BIOS. I'm staying clear of that.
    Offset works well for me and there is no extra voltage spike, even with AVX load.

    How does Offset mode works vs. Adaptive mode?
    When choosing Offset mode, you don't type in a specific voltage value, but rather a offset value of X.XXv, right?
    But what is the base voltage then?

    Apparently it has to do with VID, which are the voltages pre-programmed by Intel for the CPU and each of it's different frequencies/speeds.
    LLC and specified Offset values entered play a part in the final voltages as well. The drawback I see is any offset you enter affects all voltages from VID.

    In my case for example, I need 1.24v to run 4.8GHz on my 8700K
    With Offset enabled and set to +0.040, at load I get my 1.24v, as HWMonitor shows VID is 1.20v (1.20 + 0.4)
    That's with LLC 5. LLC 6 brings up the voltage to around 1.28v instead, throwing off the math...

    When i'm at idle with LLC 5, voltage is around 0.7v. It could be under that, but again, the +0.04v is also added to it.

    It doesn't seem like it's easy to be precise with voltages using this method, but again, my voltage adjusts according to speed and there is no extra voltage under AVX load (I've ran hours of Prime95 and RealBench to confirm). Both those benefits matter to me, so i prefer it over Manual.

    As you can see, i'm not very clear on it. I can only go off my experimentation. I've been googling for a while and there doesn't seem to be any guides really based on it. Sadly.

    Using settings above, highest Vc is 1.36V. Machine goes into low power after a few minutes, fans and lights all turn off, (hibernation is disabled) wakes up from mouse, keyboard or power button with no issues.

    To me, and I may be wrong, but the nomenclature used in the UEFI settings are not quite accurate. I've notated where these seem to be different in my view, which makes for an easier understanding of how to setup and use adaptive voltage settings.
