Hello EVGA Community,
 
Put together the Z390 Dark + 9900KS + Ballistix 4000MHz CL18 memory. These are the readings I get without doing any manual overclocking or BIOS changes (updated BIOS to the latest version right after getting it out of its box) except activating the XMP profile. The PC itself is running flawless with 4000MHz XMP profile. No issues, no crashes after a few days doing some benchmarks and of course gaming. 
 
EVGA E-LEET readings:
 

 
Screenshots above were without any load on the CPU. With load (CPU-Z stress) readings are:
 
  
 
Isn't a VCore of 1.367 (sometimes going up a bit more than that) a bit high or is there no reason for concern?
Disclaimer: I've only ever overclocked the 4770K so I can't really say I know much about what I am talking about. 
 
HWMonitor Min/Max readings:
 

 
Would like to learn what I could improve/change and maybe even push this build to get a better overclock.

EVGA Z390 DARK / i9 9900KS / EVGA 2080 Ti FTW3 Ultra
Ballistix 2x8GB 4000MHz / EVGA CLC 280 / EVGA DG-86

    First thing I would try is lowering VCore.
     
    Here are a few pics of my setup.
     
     EleetX on CPU tab shows VCore much higher than HWiNFO, or AIDA64, or other monitoring software. Seems to be correct on Monitoring tab.
     
    Running CPU-Z stress test. I prefer HWiNFO. Screenshot is too big, had to link it.

    Thanks for posting these screenshots. 
     
    I will give it a try today. There is really nothing that could go wrong going lower on the VCore, correct? I've noticed the VCore somehow correlates to the Memory settings. I have not experienced that with a 4770K and some G.Skill memory. Could it be that everything is set to 'auto' (on the Z390 Dark) rather than doing fixed/manual CPU settings?

    If VCore is too low you will get errors, or possibly BSOD.
     
    VCCSA (VSA) and VCCIO are other voltages to watch out for overvolting.
     
    I would recommend avoiding Auto voltage settings. From my experience, they tend to seriously overvolt, which, in turn, causes overheating.
     
    Best practice; start lowering VCore by .010V and testing for stability. Once instability is reached, raise VCore back up.

    Highly binned Micron Rev. E.....very interesting.  IO and SA seem a bit high already for an auto setting.

    That's really high, I see you've turned it down to highish-normal OC levels if I'm reading your screen shots correctly?

    Just now I had finally changed some settings and tried to undervolt and even go up a bit with the CPU multiplier (51) .
     
    I've selected "Lumi's 5.2GHz daily" profile and went from there. Only changes I had to make was to set the XMP profile to get a boot. Then set the VCore to 1.250 (-50% Small droop). The EVGA BIOS stress test didn't crash and I let Cinebench R20.060 do a few passes. Funny thing: I get less points each run. Had a 5111 pass and now it's down to almost 4699. 
     
    Now the question and a thing I've noticed is: Why does the 9900KS keep going down to 4.8Hz (with max temps of 70 to 78) on all cores after about a few seconds of running any benchmark/stresstest or CPU intensive application/game. Anything wrong with what I set?

    You have AVX offset of 3 in BIOS? Set to 0, and the CPU will not clock down.

    Some good news! Got the VCore down to something like this and it's stable during benchmarks, Prime95 and a few games I've tested:
     
    VCore set to 1.250V and -0.075V Core Voltage Offset. (Core Voltage Mode: Static)
    Min: 1.172V
    Avg: 1.223V
    Max: 1.251V
     
    Max temp: 68c
    XTU/OCCT/ CPU-Z: https://imgur.com/a/ubTr80X
     
    I'll keep these settings with AVX set to 0 for daily use rather than auto values at 1.3v going up to almost 1.36v or even 1.38v with AVX 3 by default.

    Great. Those are excellent voltages.
     
    Now, show us some benchmarks to see how well your system performs.
     
    Could you run OCCT Small Data Set and/or Power Supply test?

    What in the world... I think I didn't try Small/Power yet. The test in the pictures I've done was Large Data Set. Doing Small Data Set/Power Test temps go up to 94c~
     
    Removed the cooler and took a quick snap:
     

     

     
    Turned on AVX 3 in XTU and now reading low 80c~ after 2 minutes in(Small Data Set) at 4.7GHz. Guess it's still a long way to understanding everything and doing a proper undervolt with AVX offset 0 not killing the CPU.

    Yes, those tests are pretty hardcore.
     
    I was looking at your pics again, your minimum temps are quite good. What are your ambient air temps?
     
    At 5000MHz and 1.225VCore, my 9900K idles at about +10°C of ambient, e.g. ambient = 24°C - CPU Package = 34°C, even with my custom loop.

    Highly binned Micron Rev. E.....very interesting.  IO and SA seem a bit high already for an auto setting.
     
    https://www.legitreviews....z-memory-review_214072




    On my Dark, XMP1 sets VCCSA and VCCIO to over 1.4V on my G.Skill.




    That's really high, I see you've turned it down to highish-normal OC levels if I'm reading your screen shots correctly?




    Yes.
     
    Seems the Dark overvolts by a lot on Auto.




    I've upgraded to some g.skill 2x16 4000CL19 (dual rank b-die) and on XMP it runs IO 1.312v, SA 1.315v at idle, a bit more under load on my msi board, so I guess over 1.3v is somewhat typical.  The MB and ram have cross QVL approval, hopefully it's safe for the cpu.  Runs great so far.
