no i dont have Asus suite III .
There are issues with some Asus MB were bios gets corrupted and things like changing multiplier doesn't take, even though in bios it says so.
sorry but i dont understand what you mean . i dont see where is the problem in my case ?
I only said that cause every OC MB guide in last few Intel chipsets, setting manual "should" give constant voltage no matter load and your not getting that .
Only thing I can think is to try reflash bios , useing F5 defaults first .
go check any OC guide, they all say same thing with manual voltage .
here one from ROG forum just Googled

Also manual verse Offset mode .

CPU Core Voltage as said above is for Core Frequency overclocking. You can adjust up to 2.20v on this option. Take note that anything above 1.80v VCore is potentially dangerous! Obviously no voltages on the FIVR can exceed the input voltage as they are derived from it.
Manual Mode: Sets a static voltage for the associated rail. Using a static voltage means the voltage will not change according to processor load. Manual mode is therefore a less efficient way of overclocking the processor – unless AVX software loads are used (more on that in the Adaptive section below).
We recommend using Manual mode for overclocking the processor prior to using Offset And Adaptive mode. Once you have determined how much Vcore the processor needs to be stable, you can use Adaptive or Offset mode to dial in the same load voltage.
There are some contra-indications to Adaptive and Offset mode however, and we discuss those below.
Offset Mode: Setting any voltage by Offset Mode allows the processor to utilize dynamic voltage – changing voltage levels according to load. This saves power and reduces heat output when the processor is idling or under light loads.
When using Offset Mode, the voltage supplied to the processor can be increased or decreased by using a positive or negative offset. The base voltage level is determined by the processor according to frequency. You will need to use a voltage monitoring tool like AIDA in the operating system to determine what the core voltage is under load, then offset accordingly to the required level for stability.
It is advised not to use a positive offset too soon: Overclock the processor in small steps using the multiplier ratio and monitor for the voltage applied before making manual changes to offset voltage. This saves one from applying a voltage level that is too high and potentially dangerous from the CPU. Refer to the Haswell primer section of this guide for our recommendations on core voltage.
The disadvantage of using Offset Mode is that it affects the entire CPU Vcore VID stack. When power saving states are enabled, the processor multiplier will change according to software load along with the voltage. If a negative or positive offset is used, it will affect both idle and full load voltage levels.
There are instances where using a large negative offset results in the idle/light load voltage becoming too low – causing instability. Fortunately, Intel have introduced a new offset mechanism called Adaptive Mode that works differently to Offset Mode and it doesn’t have this issue…
Adaptive Mode: Adaptive voltage affects voltage for Turbo multiplier ratios only. Unlike Offset, using Adaptive does not affect idle/light load Vcore. Therefore, Adaptive mode is the preferred method for overclocking Haswell processors if one wishes to retain dynamic voltage changes according to processor load without running into issues with idle Vcore becoming too low..
There is one issue with Offset and Adaptive Mode that needs to be taken into account. The processor contains a power control unit which requests voltage based upon software load. When the PCU detects AVX instructions, it will ramp Vcore automatically beyond normal load voltage. There is no way to lock Vcore to prevent this if using Offset or Adapative Mode. This is pre-programmed by Intel into the PCU.
As an example, a CPU is perfectly stable at 1.25V using a manual voltage (static), if Adaptive or Offset Mode is used instead, it is impossible to lock the core voltage when running software that contains AVX instruction sets – stress tests such as AIDA and Prime contain AVX instruction sets. When the AVX instructions are detected by the PCU, the core voltage will be ramped an additional ~0.1V over your target voltage – so 1.25V will become ~1.35V under AVX load. If you intend to run heavy load AVX software, we recommend using Manual Vcore, NOT Adaptive or Offset Mode.
Most of us do not run AVX related software, so this is a non-issue. Either way, dialing in an overclock using Manual Vcore to determine how much voltage the processor needs under full load is best - Adaptive or Offset mode can be used to match the stable voltage later on. Simply type the target load voltage into the entry box "Additional Turbo Mode CPU core voltage" to set adaptive voltage.""
