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

    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:

    Extreme Tweaker

    - Overclocking Presets: (Ignore)

    - AI Overclock Tuner: Manual
    - BCLK Frequency: 100.000
    - Asus MultiCore Enhancement: Disabled
    - SVID Behavior: Best Case Scenario (Assuming good CPU cooling solution)
    - AVX Instruction Core Ratio Negative Offset: 2 (running AVX at max CPU speed of offset=0 may overstress CPU)
    - CPU Core Ratio: Sync All Cores
    1 - Core Ratio Limit: 52 (For 5.2GHz)
    - BCLK Frequency : DRAM Frequency Ratio: 100:100
    - DRAM Odd Ratio Mode: Enabled
    - DRAM Frequency: (User discretion depending on RAM being used)
    - XTreme Tweaking: Disabled
    - TPU: Keep Current Settings
    - CPU SVID Support - Enabled (For Adaptive Voltage Control, Disable for Manual Voltage)

    DRAM Timing Control: (At users discretion, did not modify these)

    External Digi+ Power Control
    - CPU Load-Line Calibration: Level 6
    - CPU Current Capability: 140%
    - CPU VRM Switching Frequency: Manual
    - Fixed CPU FVRM Switching Frequency(KHz): 400
    - CPU Power Duty Control: T.Probe

    - DRAM Current Capability: 130%
    - DRAM Switching Frequency: Auto

    Boot Voltages: Left all these on Auto

    Extreme Tweaker / Internal CPU Power Management
    - Intel(R) Speedstep(tm): Enabled
    - Turbo Mode: Enabled
    - Long Duration Package Power Limit: 4095
    - Package Power Time Window: 127
    - Short Duration Package Power Limit: 4095
    - IA AC Load Line: 0.01
    - IA DC Load Line: 0.01
    - TVB Voltage Optimizations: Auto

    Extreme Tweaker / Tweakers Paradise
    - Realtime Memory Timing: Disabled
    - FCLK Frequency for Early Power on: 1GHz
    (Remaining settings in this section left to Auto)

    Extreme Tweaker
    - CPU Core/Cache Current Limit: 255.75
    - Ring Down Bin: Auto
    - Min CPU Cache Ratio: 50
    - Max CPU Cache Ratio: 50
    - BCLK Aware Adaptive Voltage: Adaptive Mode (UEFI shows 1.296V at this point)
    - Offset Mode Sign: " - "
    - Additional Turbo Mode CPU Core Voltage: 1.300 (This is the actual Vc you wish to apply as a 'base' voltage)
    - Offset Voltage: 0.010 (This is the actual offset or additional voltage applied to the "Add.Turbo Mode CPU Core Voltage above)
    - Total Adaptive Mode CPU Core Voltage: 1.290V

    Note: For some reason, HWMonitor always shows much higher Vc than what is shown in the 3 settings above. See pictures below. Kept the settings shown above

    ( Settings in remaining section left on Auto. M/B displaying current voltages)

    DRAM REF Voltage Control: Did not change any of these

    - Intel Virtualization Technology: Enabled
    - Hardware Prefetcher: Enabled
    - Adjacent Cache Line Prefetch: Enabled
    - Boot performance Mode: Turbo Performance

    Advanced \ System Agent (SA) Configuration \ PEG Port Configuration
    - PCIEX 16/X8_1
    - PCIEX16/X8_1 Link Speed: Gen3
    (Left remaining section settings below at default)

    - PCI Express Configuration
    - PCIe Speed: Gen3

    Advanced \ APM Configuration
    - ErP Ready: Enabled(S4+S5)

    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.
