My methodology is completely different from Raj's. I have found out that using By Specific Core, the Adaptive voltage setting works as follows.

CPU Voltage Offset controls the voltage when there isnt AVX (light load).
Additional Turbo CPU Core Voltage controls voltage when it detects AVX (heavy/high load).

I find the highest I can go at "light load" Multiplier and vcore, then find my highest stable "high load" by adding additional voltage to the Turbo Core Setting. Usually it exceed TDP, that is when I use the AVX Offset to lower the multiplier to lower temp.

After all that then I increase the "favorite core" to higher multiplier and vcore.

I chose this method because I don't care about AVX load. I just want the highest frequency available to me. Essentially it's pretty much the same effect that Raj's blog by using the ASUS temp software to lower the multiplier when temp hits its target.

I'm not quite sure it's working the way you think... if the light load is a turbo multiplier, then the turbo voltage is applied to the single core. I also run "by specific core" but with straight adaptive (and the ATCT except for bench clocks)
besides... AID64 w/o FPU is still an AVX load.

I just doubled checked. when I run AIDA64 w/o FPU and moved my CPU Voltage setting subtracted .30mv from my initial .110, HWINFO64 reports a subtracted .30mv difference.

Then when I use Prime95 it added the +.05mv, which is what I have in my Turbo CPU Voltage setting. (although it crashed in 10mins)

Examples of how much voltage is applied in various scenarios (Turbo voltage set to 1.30V):








The issue with the Adaptive portion of the stack is it becomes active whenever the cores enter Turbo state and are faced with load, so gets applied to the AVX and non-AVX ratios where both are Turbo ratios. There is a slight 30mv disparity with high current AVX loads, but this isn't sufficient to prevent throttling under heavy AVX loads.If we use an offset to try and reduce the VID for the AVX ratio, then that offset also gets applied to the light load ratio, which prevents us from fine tuning the voltages. And then there's the caveats of using large offsets and what that does when the CPU comes out of idle.

The Additional Turbo Voltage setting is supposed to be used to define the max VID and it's supposed to be entered as whole value. Ideally, we need two distinct values, one for light loads, and one for the AVX ratio.

That's why we developed the Thermal Control Tool. The current control mechanism offered by Intel doesn't allow the fine tuning some of us desire. Of course, you don't have to use it, and it is in no way necessary to do so. The article was written for people that care about using the "correct" level of voltage for each scenario.

HTH

Can you elaborate on this? entered as a whole value, meaning? I always thought that the Additional Turbo Voltage Value was whatever the VID Value + Offset Value + Turbo Voltage

so if VID is 1.23 and the Offset is +.01 and Turbo Voltage +.05, you get a max Vcore usage of 1.29v.

Hello

0.05V is not valid for the additional turbo field. The value entered needs to be the actual voltage value desired when at max multiplier.

Hey everyone,
I've been reading the thread every since I got my 6850k and I've been having the same bsod screen when overclocking or rending in 4k. But one solution that actually worked for me is updating the Windows 10 to the Anniversary edition update. That smoothed out every thing from no more bsod to overclocking to no more random reboots.
