(4.4Ghz 1.285V) i5 6600k core frequency remains stable during idle without significant voltage reduction
Hi! I attempted to increase the clock speed of my i5 on the gigabyte GA-z170-d3h board. At idle it was around 1.260-1.275v, and about 1.220v when running at full load in occt or cinebench r15. The frequency dropped to around 800 MHz during idle but stayed higher than during full load (all cores at 4400 MHz). I enabled power-saving settings and adjusted the multiplier to 4.4, setting the voltage in the vcore section. I want to avoid stressing the CPU, so I prefer it not to run at that high voltage continuously. Thanks for reading and helping!
When the core voltage is set in manual mode, the motherboard configures the VRM to disregard CPU state and maintain a constant voltage. The reduced voltage observed under load comes from the voltage drop between the VRM and the monitoring chip's reading point. To ensure core voltage matches the load, you must adjust the offset voltage, though this approach might result in less stable overclocking.

When core voltage is set in manual mode, the motherboard ignores CPU state and maintains constant voltage. The lower voltage observed under load comes from voltage drop between the VRM and the monitoring chip.
To have core voltage adapt to load, use offset voltage adjustment, though this might reduce stable overclock performance.
If offset isn’t used, why do frequencies drop in manual mode? In manual CPU settings, it should still run at 4.4.
Regarding Gigabyte boards, how can you apply an offset OC? The voltage section shows only two options related to CPU voltage; the second one is now grayed out and labeled "Automatic Vcore," which is set to auto.
Offset OC? What does that refer to?
Adjusting the multiplier alters the MAXIMUM multiplier setting. When SpeedBoost remains active, the core clock will continue to be reduced even during light usage.
If you wish to manually adjust the core voltage, ensure it is not set as automatic first.

Offset OC? What does that mean?
Adjusting the multiplier affects the MAXIMUM multiplier. If SpeedBoost remains active, the core clock will still be reduced under light load.
If you wish to manually adjust the core voltage, you must disable automatic settings first.
Therefore, if I want my CPU to down-volt, I need to revert to the original configuration, then use Automatic Vcore (DVID) to increase the voltage?
But is this a significant issue? Is my current 1.285 safe for everyday use? Can I remain in this state without worrying about my computer's health?
Running the chip beyond specifications is common, but no one is sure what will happen or when it might happen. If Intel were completely certain they could make a 4.4GHz CPU that would last the full warranty under any worst-case use, they probably would be sending pre-assembled CPUs at that speed.

System operates beyond acceptable parameters, uncertainty about future behavior and timing. If Intel had full certainty they could manufacture 4.4GHz CPUs with a guaranteed lifespan across all conditions, they would probably be distributing fully functional chips at that frequency. Thanks for your assistance! I also have another query—after clearing CMOS, resetting the BIOS still doesn't restore the Dynamic Vcore setting. I'm unable to assign a value; the display shows a dark grey color.
