I have to say, this thing is beautiful.  The install was almost flawless.    Disabled my second M2 drive and installed the OS from a thumb drive.  10 minutes!
 
the only glitch I had was no video on either SLI cards or onboard video.    I had to disable PCI lanes 1 and 2 to get the on-board video to work (because I seated two cards).   I went ahead and did the full install and then concentrated on the problem.   First thing I did was go back into bios and disable the onboard video.  no video from my cards in SLI (on a water loop).  So then, I took both cards slightly out, re-seated, and no problems.   The was after I turned PCI 1,2 back on.     Hindsight,   I should of just reseated the cards to begin with.   but dealing with two cards hooked to water bridge was difficult. 
 
So no issues now.   Seems rock solid but everything is on auto with XMP 1.   This..  was easy.   I'll post more here when I get things finalized.

    This is true...but I've had my share in the past 20 years of building these things.

    preliminary testing tonight.   I performed an auto overclock in the bios and it set itself to 5.1ghz.   vcore 1.36    idle temp was 23C
     
    I ran 40 minutes and passed an intel extreme tuning utility stress test. On water, the CPU was about 57C average.   That's all I can do tonight.   I will probably back down vcore and see how it does as I've read the auto OC gives it more juice than possibly needed.

    Damn thats a descent chip. Wish mine wasnt poop. Then again i ran auto oc with 4600 speed ram so i have a feel that could have drove things a lil low.

    I know what vdroop is.  can someone explain the percentages?    when it say 75% (large vdroop)  does that correspond to 75% of the absolute drop?   Or does it account for only 25% drop?    also, explain negative percentages.  would -75% be the very minimal vdroop experienced?
     
    bios values:
    90
    75
    50
    25
    -25
    -50
    -75

    ran some testing this afternoon.
    5.1 ghz passed with no vdroop.   vcore 1.335   57c temp
    5.2 ghz passed with no vdroop    vcore 1.345    65C temp
    5.3 ghz failed with no vdroop all the way up to 1.4 vcore.   I stopped there.  
     
    these were performed with the intel extreme tuning utility stress test for 30 minutes each.  Figured I'd see what I'd get before any sort of long term test. 
     
    Not sure what a 9900K will do with vcore.   How high would you guys go?
     
    this MB combo  will be my 24/7 computer so I'm not really trying to chase the highest overclock - to the extreme

    While I don't have the EVGA Z390 Dark it sounds like the percentages are trying to add or subtract voltages depending on where you set it. Does your board have LLC (Load Line Calibration)? It sounds like that setting is very similar to what LLC is designed to do ie keep a flatter voltage curve when the CPU is under load. Again I don't have the board so I can't verify. 
     
    As for what I would set your CPU at, I suggest a nice round 5Ghz with as little voltage as possible if this intended to be your long term 24/7 rig. The percentage gains going beyond 5Ghz really aren't noticeable or needed vs the increased voltages they usually require. I would suggest using Prime 95 26.6 as is doesn't have AVX instructions and set the torture test to custom with min and max FFT set to 12. This will really hammer the CPU and usually if it passes an hour or 2 of that it will pass nearly anything you can throw at it. 
     
    I settled on 5Ghz with 1.3v and LLC set to 5 in BIOS with both long and short duration power limits set to max to avoid any throttling. I set a -2 AVX offset ratio to avoid any undue strain if or when AVX instructions are used and set my CPU current max to 140%. This gives me a nice stable 5Ghz across all 8 cores and load temps in 60s across all cores.

    Yes.  It's load line calibration.  Just wanted to know what the settings meant as far as percentages of VDROOP.    And it will be my 24/7 and 5ghz probably will be my setting.  Back it down a bit.  Thanks for your advice.   How you doing old friend?  Kids doing ok?  how old are they now (I'm assuming you had more than one)?   it's really good to see you hanging around here.  I saw another forum where they where binning 9900K ships and looking at serial numbers.  Remember those days when you did that? k that whole big list you kept on the Q6600, I believe

    Doing pretty good these days, how about yourself? As for age lets just say I'm on the other side of 40 (yikes! :P) and yes I have 2 little reprints of the original both doing well both are in school (time does indeed fly). As for me binning CPUs these days lol yeah that would be a gigantic list and something I no longer have the time or will to keep up with. While I do still keep one foot in the door with overclocking and tinkering it's hardly my field of expertise anymore. I'm much more of a casual overclocker and just want a system that does what I want it to after I'm done setting it up. I'm done with the days of swapping hardware every few weeks, testing, retesting....ect.

    Yeah, lot numbers.        Going to create a new mods rigs.  My last one was with a caselabs sth10 magnum, which I love (you can't buy caselabs new anymore- so It's vintage I guess).  So I removed my motherboard and inserted the dark.  Same old graphics.   I'll do something about that later.      I haven't been gaming as much as I do on my xbox one x I got for 4K home cinema.     I need to take a few pictures to get the mods rigs up.

    going to use this post as my own little log and my findings.    Initially I used the robot overclock to see what my CPU would do.  It selected  1.36 volts vcore and gave me a stable 5.1 ghz after an hour of testing with intel extreme tuning tool.  That's everything on full auto. 
     
    I then set the bios to no vdroop and lowered my vcore until the test failed.   @5.1 ghz the test failed at 1.335 set in the bios and was one hour stable when I went back in and changed it to 1.34 vcore in the bios.  This established my baseline vcore for 5.1 ghz.   was 1.34 set in the bios.
     
    I then tested 1.34 vcore with vdroop set to auto (which I assume is what the robot does).    Vcore fell to 1.32 under load indicating auto allowed some vdroop under load.  Really, it varied between  1.32-1.329 under load (it fluctuates due to ripple I guess) on auto vdroop.   
     
    I then took the value of 1.329 (highest range load vcore that maintain stability) and plugged that into the bios and set vdroop of -25%.    Booted in the OS and discovered in Eleet vcore idle was 1.34 and after placing a vdroop setting of -25% discovered under load, the vcore fluctuated 1.334 to 1.337 under load.  Definitely over my baseline vcore voltage 1.34 on auto settings.         I discovered that -25% vdroop added .005 vcore at idle than what I set in the bios.  1.329 that was set in the bios was subtracted from 1.334 and that gave  0.005 volts.   So when I put 1.329 in the bios, it added .005 to idle vcore and when  load test was applied, it varied between 1.34 - 1.337 under load.   So -25% kept idle vcore 1.34 consistent under load if not added another .003   Load ranged in a net 0.00 to 0.003 gain in vcore.   
     
    Since I determined that -25% gave me 0.005 more at idle and ranged from 0.00 to 0.003 more at load, I decided to subtract 0.005 from 1.329 and put 1.324 in the bios.   Booted back into the OS and saw that idle was a steady 1.329 that was proved as my lowest stabile vcore.   I applied the intel test for another run and load vcore ranged from 1.329-1.334      
     
    Conclusion.   -25% adds 0.005 volts to what you put in the bios at idle in the OS ....and  adds at most  0.003 volts under load and at least keeps idle vcore when applying load.    Hopefully this helps people realize that the vdroop settings affect idle and load vcore and what you put in the bios will be different when booted in to the OS and applying full load. 
     
    this helps me to determine that at 5.1 ghz, no matter what I select at vdroop, I will need to maintain 1.329 volts under load.   I can go back in and plug in other vdroop settings, start a stress test and I bet as long as 1.329 is maintained, I can use any setting.  Of course I will have to adjust bios vcore up or down to make sure of that.

    next up,      5.1 ghz    @ -50% vdroop
     
    Bios setting 1.324
    Idle in OS  1.329-1.334
    Load   1.34- 1.352 volts
     
    -50% vdroop added 0.005 to 0.01 at idle over bios setting
                        added 0.023 volts over idle at load  
     
    Load to load comparison between -25% and -50%   is    0.023 - .003 = 0.020 volt increase over -25% vdroop setting. 
    -50% vdroop adds .020 vcore over idle during load. 
     
    determinations performed with eleet and intel extreme tuner.   actual voltages should be done with a voltmeter but this quantifies an increase by just looking at voltages in Eleet.

    5.1 ghz  -75% vdroop
    Bios setting 1.324
    Idle in OS  1.334-1.337
    Load  1.352- 1.376
     
    -75% vdroop added 0.01-0.013 volts over bios setting at idle
    added  0.018 to 0.042 volts over 1.334 volts idle   (1.352 - 1.334 = 0.018 low range         and         1.337 - 1.334 = 0.042 high range)
     
    -75% adds ~0.022 over -50% vdroop    (
    -75% adds ~0.042 over -25% vdroop     (1.376 - 1.334 = 0.042)  high ranges between -25% vdroop and -75% vdroop
     
    One other finding is that idle vcore creeps up just a bit in range with each consecutive minus in percentage.  no more than 0.008 from -25% to -75%

    I am surprised that you went Serial on the Graphics Cards and not Parallel.
    I am liking parallel more and more now and also for Support of the Cards, saggy stuff

    conclusion
    -25% added 0.005 to vcore from what I put into the bios and added 0.003 to vcore under load.   Minor increase.  Probably to maintain idle vcore while allowing some voltage ripple effect.
    -50% added 0.005 to 0.01 to vcore from what I put into the bios and added 0.020 to vcore under load.  Small increase
    -75% added 0.01 to 0.013 to vcore from what I put into the bios and added 0.018 to 0.042 under load   Moderate increase 
     
    Hope that helps understand how negative values in progression add to vcore under load.

    I'm not talking about graphics man, get with the program.  anyways, I have a triple and quad on the same GPU loop (apart  from the CPU Loop).  the temps between cards may of varied 2-3 degrees.  Not worth it.

    Out of curiosity, what do you feel are the pros and cons of serial vs parallel tubing for gpu SLI? To my understanding serial provides a greater pressure, while parallel has greater flow rate which could be better for more restrictive systems. Differing takes on how much it actually affects temps.

    Along with the pressure versus flow is in series (generally the bottom card is fist just because of tubing routing) the first card gets the cooler water then the second card gets cooled. Where parallel both cards get the same fresh intake flow. How much of a difference depends on what the work loads are and the water blocks I guess.
     
    In reality, yes once the loop gets up to temperature thing should normalize. How much of a temp difference between the cards and weather or not it is affecting things is subjective and in the end it is up to you weather or not it matters.
     
    Personally parallel makes more sense - it is up to you to decide
