What is your speed and temps on an AVX workload?

Sounds like a sweet chip you have there!

cpu-z stress test  at 5.0 ghz  , 1.238 volts, temp, 48c to 58c ambient 72f, 5.3 ghz ,1.373 volts, temp 62c to 72 c ambient 72f,  Heaven stress test 5.4 ghz, 1.411 volts 22 c to 53 c, ambient 40 f with garage door open.5.4 and above Garage door is open!





What is that graph you are using?
 
For me, CPU-Z does not display Core Voltage, only VID.
 
 
 
Thought I might post mine running CPU-Z stress at 5300MHz.

With a EVGA Z390 Dark, CPU-Z only displays the VID. 
On my Asus Z390 Maximus XI Formula, it displays core voltage.

You can use EVGA Eleet software or HWInfo 64 to read the actual voltages.

As for the high voltages, I had the same thing and I think it killed the CPU. I set Adaptive voltage to 1.3V and it was giving the CPU 1.45V and more. The only way I could get accurate voltage settings was to use manual Voltage. The only problem is I did not know this right off the bat because I didn't know CPU-Z didn't read properly.

I think this is a result of not having adjustable AC and DC load line settings. On Asus Z270/Z370 you had to set those voltages to 0.01 offset to prevent similar behavior to what I see on the Dark when using some kind of variable voltage setting. I hope they do something with it soon.

I agree the Dark needs Load Line settings.
 
I find that using negative offsets helps with the overvoltage.

All you really have to do is change the default LLC setting to -75% if all you want is for your 9900KS to function as intended from Intel.

I would highly caution anyone with the Z390 Dark to stay away from setting voltage in bios to Adaptive.
I found with mine over time it would increase the amount of Vcore it was throwing at the CPU. I notice this by the increasing core temps over the last several months. I always keep my core temps on display.  I would then check it under stress and voltage was getting way up there. So I would decrease the target Vcore setting when this happened. Ended up around like .95 Vcore and it was still throwing around 1.38 -1.39 at it.
You can see what I was experiencing in this thread.
 
I then a few days ago changed my voltage in bios from Adaptive to Override. Gave me much finer and realistic control over my Vcore. It also allowed me to overclock a little higher, have just increased from 5.1 GHz on all core of my 9900k to 5.2 GHz on all cores and stable, core temps in low to mid 70's while stressing. Target voltage set to 1.315v and -75% Vdroop. While stressing it bobs up to 1.36v occasionally. I never could get it above 5.1 when using Adaptive voltage. Going to run it like this a few days at 5.2 GHz and if all still looking good may even try for 5.3.
 
There is something awry though with using Adaptive Voltage in this Dark board. I would highly advise folks to stay away from it, and EVGA should really take a look at it.

Maybe I am just paranoid, but now that you mention it, I might be having the same thing happening with my Dark.

Changing the LLC does not have an impact on that 0.800mOhm number. 




I noticed that.
 
Not sure if it should, but do the Asus and Gigabyte boards change?


Changing the Loadline Calibration value does not change the AC/DC Loadline mOhm value on Asus or Gigabyte.
Changing the presets for "Internal AC/DC Load line (Gigabyte), SVID Behavior (Asus), AC/DC raw mOhm values (Gigabyte and Asus)" will change the AC/DC values.
Changing the raw direct AC/DC values has higher priority over changing the presets.
 
Asus: Best case scenario sets it to 0.01 mOhms.
Worst case scenario sets it to either 1.6 mOhms or 2.1 mOhms 
Typical sets it (I believe) to 1.2 mOhms.
Intel fail safe sets it to 1.6 mOhms.
 
Gigabyte:
CPU Internal AC/DC Load Line:
Power Saving: 0.4 / 1.3 mOhms
Balanced: 1.0 / 1.3 mOhms
Turbo: 1.6 / 1.6 mOhms (1.6 is max Intel spec for 9900k)
Extreme: 2.1 / 2.1 mOhms (2.1 is max intel spec for 6 core processors).
 
The AC loadline value is used to get the idle and load voltages on Auto (and dynamic offset) voltages.
DC Loadline is used for power measurements (VID/CPU Package Power).
 
eVGA setting this at 0.8 mOhms is a bit on the low side.
