even + 40mv on both didn't help at all until i use + 0.20v as offset and the rest on adaptive! Rock solid OC smile.gif that increase my idle temp by 2-4c but its stable now..

No idea why that happen but that work for me... cheers.gif

I think you mean +0.020V (20 mV) not 200mV offset. Bios and auto rules have "matured".. auto in offset on ASUS x99 boards works fine and has not led to over or uncontrolled voltage on the 2 running here.

I have a question :

On my system, I set this to test :
CPU Core voltage => Adaptative
Offset mode sign => +
CPU Core voltage offset => 0.005V
Additional Turbo Mode CPU Core Voltage => 1.115V

So, total adaptative voltage in Bios = 1.12V

At full load (Example OCCT) => In CPUZ and Aida64 => Vid under load = 1.132V
At medium load (Gaming) => In CPUZ and Aida64 => Vid under load = 1.142V

First question : where do come from these 1.132V - 1.12V = 0.012V for full load ?
I assume this is due to the fact that under load, Vid increases ?

Second question : why is the Core voltage lower at full load than medium load ? (1.132V versus 1.142V)
This I don't understand.
At full load Vid should be higher than at medium load ?

Whatever LLC setting, it is the same (LLC only acts on Vccin by the way).
My C states are disabled.
Speedstep and Turbo enabled of course.

if you are ACTUALLY referring to VID and not VCORE, the VID value has meaning within the stock turbo multipliers. Once you use mutipliers higher than the stock multipliers, VID is basically meaningless. TYrue, each CPU is programmed with a VID value outside on the operating specifications, but the number can be misleading as to what the cpu needs at that frequency. If you are refering to VCORE.. HWE will add mV above the voltage set in bios normally. VCCIN is where you want to control this raise by using an appropriate amount og LLC (vdroop). thumb.gif

I also have higher max load vcore than medium one, figured it was lvl 5 llc.

Tho my deviance from targeted turbo voltage is up to 7mv, but my offset is + auto.

Edit: opposite of what i wrote, I must stop writting from bed @ 3AM.

LLC only affects VCCIN on x99, not (directly) vcore.

I have "max load Vcore" (OCCT) LOWER than "medium load Vcore" (Gaming)

OK, thanks.
But why do I see in CPUz 1.132V during OCCT while I see 1.142V during medium load as gaming ?

I would have bet the opposite : 1.142V during OCCT and 1.132V during gaming....

I wanted to say i have the same but just noticed I wrote the opposite. I'm an idiot biggrin.gif
When i run stress tests vcore actually drops by ~5mv from low/medium load.

From My side it is 10mV drop between light load (gaming) and heavy load (OCCT)
