always, frequency stucked at 4.2Ghz in some programs but the voltage goes down to the idle 0.96....so I dont care....at least the voltage are cool....
that will not kill my CPU and the electric bill...I hope
If in aida64 your CPU is downclocking to 1600mhz and voltage is downvolting too, you are all set. CPU-Z has bugs for this, well known. It doesn't mean your CPU is not downclocking, don't worry, you are fine

Use aida64 to monitor.
Use offset voltage. in order to do this, pay attention to your VID.
Lets say you run stable at 4.5 Ghz with 1.3v (Vid is reporting 1.33v)... the use negative offset of -0.03v to reach your desired voltage. But on idle, your VID voltage will downvolt to lets say 0.93, so having a negative offset of -0.03 will also drop the idle voltage to 0.9v. Please Read the guide BelowEIST
(Be sure to set it at enabled and not auto

Offset is adding or subtracting a certain amount of voltage to get a processor stable at max load. In other words, it usually only gives the max volts to the CPU when it's running at the max load/speed and of course when required. Whereas in fixed voltage, you just fix the prescribed the no. that you wanna set and according to the LLC that you've set, the motherboard goes ahead and sets that voltage accordingly.
Offset is kind of what you explainded but not totally.
Offset is based on VID and not according to the LLC.CPU Core Voltage Offset Mode OverclockingOr Here

Overclocking Using Offset Mode for CPU Core Voltage
Many of you have asked us how to use Offset Mode in BIOS to over or underclock a CPU, so we’ve put together a quick guide that should help users better understand how to use
the Offset Mode function.
We’ve tried to keep things as simple as possible, while providing enough information to help further understanding of this feature.
Intel programs each processor with a stock voltage using a binary code (known as VID). This binary code is utilized by the motherboard voltage regulator module to set the correct
voltage for the processor at stock operating frequency.
At stock, Intel’s power saving features such and SpeedStep, EIST and C-States are active. Under light loading conditions, SpeedStep reduces the CPU multiplier thus lowering the
operating frequency. EIST dynamically lowers the VID while various C-States sends parts of the processor into low power or off state to help save power consumption.
As we increase the processor’s operating frequency, we’re going to need to increase VCore in order to facilitate higher switching frequencies of the processor core.
The conventional method of doing this is simply to set voltage control to manual mode and type in the required voltage for stability at the selected operating frequency.
However, the side effect of using this method is that the applied voltage code (VID) remains static under all loading conditions so we end up increasing power consumption
and heat production under light loading conditions unnecessarily.
The workaround for this is to use Offset Mode in BIOS to set the processor’s operating voltage. In order to do this on the ROG boards we need to set CPU Voltage from
Manual Mode to Offset Mode:
Note that on the ROG boards; Phase Control needs to be set changed from Extreme to Standard, Optimized or Manual in order for Offset Mode to become available in the CPU Voltage menu.
With these two functions set, we can move back to the previous screen and change the CPU Turbo multiplier to a higher value, so that the processor ramps
to a higher frequency when under sufficient load from software:
As pointed out in earlier guides, most CPUs will scale to 4.5GHz with the right cooling. We’d recommend you start out lower than that to get a feel for
how well your processor scales with voltage. In our example we’ve selected a 43X multiplier, giving us a Turbo frequency circa 4.3GHz under load.
At this point we can reboot the system; the CPU voltage will be offset from stock voltage automatically – as you increase operating freqeuncy, the default voltage
will automatically increase. In order to find out what the new load voltage is, we can boot Windows and run a stress test, while keeping ROG CPU-Z open to get a rough
idea of how much voltage the processor is seeing under load or if you’re handy with a multimeter, the ROG boards have a measurement point situated near the DIMM
slots allowing for a more accurate reading.
BIOS may have applied more voltage than the CPU requires for stability at 4.3GHz, in which case we simply enter BIOS and use the
Offset Mode function to decrease VID appropriately:
With the “-“, (negative) voltage range selected, the voltage you select will be subtracted from the load voltage we saw in the operating system.
For example if our full load voltage was 1.376V in the operating system, and we’d like it to be 1.32V instead, we simply set 0.05V as
the negative offset (1.37V-0.05V=1.32V).
Bear in mind though that this will also offset your idle voltage by the same value. As an example, with the default voltage settings,
our 2500K processor’s idle voltage (at 16x CPU multiplier ratio) is 1.045V. If we subtract 0.05V from the full load voltage, the idle voltage
will be reduced by the same value
So if we offset the voltage too far with the negative voltage scale, there will come a point where the idle voltage is no longer sufficient to sustain
the idle processor clock frequency.
If we wish to add voltage to the full load VID, we simply use the + offset and increase to increase the voltage level. The “+” offset scale isn’t as direct
as the” –“ scale when it comes to changing voltage, that’s because one of the features of SVID (serial VID) is that it allows the processor to request
voltage based upon operating frequency, current draw and thermal conditions- hence adding 0.05V to 1.376V results in a full load voltage of 1.40V.
Similarly the idle voltage is increased by only 0.025V, too
