 Sort of on topic, I tried running AIDA64 Stability Test with only FPU checked.
VCore at 1.250, Adaptive, VDroop -50%, XMP1, C-States off, HT enabled, AVX0.
Bios 1.07 resulted in several BSOD; 0x3B, 0x3D, 0x0A all of which are related to low VCore.

However, using BIOS 1.03 with identical settings, FPU ran without BSOD, although temps were in the low 90°C.

Don’t set a voltage with the most recent bios. Leave it on auto adaptive and use the LLC to control it. Start with default and test. It will likely be too high. Keep adding more droop until your voltages and temps are in check.

What is this LLC you are referring to using in the Dark?

Load-Line Calibration, aka VDroop.

 The Z390 Dark is a board meant to get overclocking world records.  And with the best transient response (someone needs to donate an Apex XI to buildzoid so he can test that vs the Dark), it will do just that.  But the Dark is sorely missing some features other boards already have:
 
Current (Amps) monitoring (does the VRM controller on the dark support this?)
On-die sense voltage monitoring (this is the exact CPU voltage that the CPU is getting, unaffected by power plane impedance. All maximus XI boards use a diode to wire the Super I/O chip to read from the CPU die sense.  Boards with the IR 35201 and Intersil VRM controllers that have VR VOUT access will show this as VR VOUT.
 
AC and DC Loadline settings. <--this is an issue.
 
The lack of access to AC/DC Loadline is a pretty huge thing.  It's unknown just what the Dark is using for AC Loadline. (AC Loadline is only used on "Auto", "offset" or "adaptive" voltage modes, but a high AC Loadline must NOT be combined with a high vdroop reduction !! AC loadline is ignored on fixed vcore modes)
 
Can you go into HWinfo64 and go to the "CPU" information section, scroll a few pages down, and look for the AC Loadline value?

I checked HWiNFO64 v6.12-3930, and I see nothing labeled AC Loadline.
 
Possibly it is named something else?

I never remember seeing that with the sensors. Interesting. 
 
Does it show up with all the sensors or just in the summary?

It's not right here?

IA AC and DC Load Lines have to do with Internal CPU Power Management while CPU Load-Line has to do with External CPU Power Management.

Setting these values (IA AC/DC Load Line) keeps the Adaptive Mode voltage closer to the user-applied value when the processor is under full load, otherwise it makes my Vcore (and consequently cores temps) skyrocket big time under load.
 
GT Load-Line is for the iGPU.

The CPU Load-Line level is not shown in HWiNFO for me, although the resulting voltages and temperatures for different levels are.

See: The (Asus) Kaby Lake Overclocking Guide near the bottom of the page.

What motherboard are you using? 
 
I don't know with the Z390 Dark that a user can change the IA AC/DC Load Line setting which shows up as 0.800 mOhm in HWInfo for me. Maybe its an option in the XOC BIOS. I'll have to explore some when I get home. 
 
I do appreciate the clarification though. I was confused as to why this 0.800 mOhm setting didn't move when I adjust the LLC in the BIOS.

You don't have a sig line on my screen, but Asus. Got it.

Get it now?

I think you missed the point...again. I can't see your signature, because my options are set to not show signatures.

How do I get that to display? All I have is this:
 
 

Try unchecking "Show summary" and "show sensors"?
it should bring up the main window then at the top left.
If you have show summary checked, it won't show it.

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

Put a I 9 9900 KS in Msi Ace Z390 yesterday. Running a 360 Aio ,push,pull on fans and it runs very cool with 100 percent load. 5.0 ghz 1.286 to 1.271 volts for hour . Temp. was under 55 c most of time on all cores, did see one core get  to 57 c and drop back down. Using Kingpins thermal paste. Looking forward to pushing this cpu at 5.2 Ghz 100 percent load about 65c at 1.310 volts. I did update Bios for new cpu. I bet with custom water loop 5.4 Ghz could ???

Those are great temps and you could be on a good OCing chip as well.  The 320mm AIOs are close to custom.  Really no point in spending the extra dough since it will cost much higher but all up to the user if they want to head down that route.  Yes, you might be able to get that high but it's hard to say.  I think going 5.2+ in general usually enters you in exotic cooling (LN2, etc.)

Put a custom loop on i 9 9900 ks and gpu and runs at 5.4 without breaking a sweat and 5.5 and above, http://www.3dmark.com/pr/177913 http://www.3dmark.com/cg/4632298
