Hello guys. 
 
My specs:
9900k 
z390 Dark
gskill tridentZ 3200 cl14
 
I can not run the memory kit on its XMP Profile or any other manual profile that runs on more than 2800MHz.
I tried using profiles from buildzoid, luumi and other people.
 
I used the exact same components on a different motherboard (z390 phantom itx) and it ran the XMP profile with 3400MHz
I also tested an older kit (gskill ripjaws 3200 cl16). It ran fione on the z390 phantom but could not run on the Dark. Eexcept i did no used a frequenzy above 2800MHz.
 
I even contacted the suppport and they did an RMA on my Board. Now I have  the same Problem with the second Board.
 
The problem only occurs in dual channel mode. If i use one stick (doesn't matter which one) it works. But only in the DIMM2 slot. It is exactly the same on both z390 Dark motherboards i have used.
 
The memory setting i can run at the moment is 2800 10 12 12 28
 
Does anybody have an Idia how to  help?
 
Side question: How do  i make my M.2 Sata SSD work in the M.2-KEY M(2) slot work?

    CL14 is very low latency at that frequency. Native 3200MHz RAM runs at CL22. You probably need to bump the VCCSA voltage. That is probably what G.Skill support would recommend.

    1. Make sure the latest BIOS (1.07) is installed.
    2. It's essential to know the G.SKILL part number of the RAM, post it.
    3. What is the VCCIO and VSA voltage at right now?..Set them to 1.3V.
     
    That's all for now.

    So you used the same 9900k on that board? If no, then it could be a weak imc.

    Try turning off hyper threading.

    You know, it's crazy but the F4-3200C14D-16GTZR isn't on the EVGA QVL list, but it is on the G.Skill QVL.  Huh.  Maybe G.Skill just assumed it would work but it doesn't?
     
    https://www.evga.com/support/motherboard/
    https://www.gskill.com/qv...F4-3200C14D-16GTZR-Qvl
     
    They have the F4-3200C14Q2-64GTZ kit on the QVL, but that's a 8 stick kit which is really an ultra high bin to run quad channel dual rank on X299.
     
    Maybe try an overall looser timing like 3200 16-16-16-36 and go from there?  It looks like the board really doesn't like tight timings at XMP voltages based on the QVL, so maybe try higher dram voltage, looser timings and higher clocks?
     
    Are you doing all this with a CPU overclock?

    Are you just using XMP timings or working up? 
     
    I REALLY suggest working up your own timings after resetting the BIOS to make sure you have all of the old auto settings flushed. Here is a great guide to follow. 
     
    https://github.com/integralfx/MemTestHelper/blob/master/DDR4%20OC%20Guide.md
     
    ETA: I've noticed some boards will will raise the VCCIO and VCCSA voltages as soon as you turn on XMP. With my Z390 Dark it set both to 1.3500v. With an Asus Maximus XI it was over 1.4000v. More isn't always better. Try backing both off to 1.1500v. It's worth resetting the BIOS to loose any old memory training and make sure you are working from a clean slate. Leave the CPU on its stock clocks for now until you get the memory going.

    I did some testing now. I tried everything suggested. I also tried "Lumis daily" bios profile. And they all work if I run the memory on 2800MHz as soon as I go 2900MHz or higher it does not post.

    Don't shoe horn in memory timings by loading someone else's profile. You don't have the same memory, MB and CPU. Even if they are the same model, they are not the exact same. The only reliable way to OC memory is to work up your own timings. I suggest the following... 
     
    1. Reset the BIOS. This will ensure you are working from a clean slate and not using old memory settings or old memory training. Do not overclock the CPU. We are only working on memory. Leave every BIOS setting as close as you can to its default configuration. 
     
    2. Set the DRAM voltage to 1.40v.
     
    3. Set VCCSA & VCCIO to 1.1500v. 
     
    4. Set the primary timings to 16-20-20-40 (tCL, tRCD, tRP and tRAS).
     
    5. Set the memory speed to 3200 Mhz. 
     
    6. Save setting and reboot. The computer may reboot a few times as it trains the memory, be patient.

    If you are still within the return range for those sticks, I would send them back and go for something with looser timings. Turning off hyper-threading will give you more stability on the RAM since hyper-threading is heavily dependent on the memory.

    Rain just curious here, are you suggesting to turn off HT completely or just to test/train?

    Silly question, but is the MB bios set properly to do memory training?  On some MB there is a setting that disables it.

    Testing primarily because the OP can't boot with XMP enabled. XMP works with specific CPU configurations. Just because it's on the QVL list only means that it's been tested with a certain CPU configuration and that information is never really documented. My i7 9700K could run memory so much faster than any other CPU when considering stock configurations. I could probably turn off hyper-threading on my i9 9900KS and get a an awesome overclock on my RAM since I also get more power allowance.

    Hello guys. 
     
    My specs:
    9900k 
    z390 Dark
    gskill tridentZ 3200 cl14
     
    I can not run the memory kit on its XMP Profile or any other manual profile that runs on more than 2800MHz.
    I tried using profiles from buildzoid, luumi and other people.



    I have a similar setup to yours (Z390 Dark, 1.07 Bios) and running G.Skill F4-3200C14D-32GTZSK (https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232378?Item=N82E16820232378) which is listed as running @ 14-14-14-34.
     
    No offense to anyone in this thread, especially RainStryke, but I tried everything suggested by others in this thread and nothing worked with Z390 Dark using XMP @ 14-14-14-34. Couldn't get it to post, same as you.
     
    I decided instead to search Youtube for 'Z390 Dark Memory' and found this vid: https://www.youtube.com/watch?v=9QcbF7AvDhQ
     
    I took his suggestions for overclocking memory on Z390 Dark and now I can finally get my memory to post and work fine (tested using AIDA64 Stress Test) at it's correct timings, 14-14-14-34 with 1.40v and VCCIO + VSA both set to 1.250.
     
    Also, watch Buildzoid's Z390 Dark BIOS Walkthrough (very informative guy): https://youtu.be/5l7Vr_R4irE?t=1883 
     
    Finally, I suggest you turn OFF hyper threading in the BIOS as its irrelevant for the 9900K, and having it OFF will allow you to better overclock CPU+MEM (unless you game @ 720p for some odd reason): http://www.redgamingtech.com/does-intel-hyper-threading-hurt-gaming-performance-i9-9900k-analysis/

    Thanks for the help again. I will test everything again on the weekend.

    Turning off HyperThreadibg is not an option.
    I am playing on 1440p 240Hz and my 9900k (5.3GHz) is on 100% almost all the time.

    What are you running that is pegging your CPU like that?  On 16 threads?
     
    Turning off HT might improve older lightly threaded games but will tank the scores in some benchmarks (3dmark) and some multi thread optimized apps.

    I did some testing now. I tried everything suggested. I also tried "Lumis daily" bios profile. And they all work if I run the memory on 2800MHz as soon as I go 2900MHz or higher it does not post.




    Don't shoe horn in memory timings by loading someone else's profile. You don't have the same memory, MB and CPU. Even if they are the same model, they are not the exact same. The only reliable way to OC memory is to work up your own timings. I suggest the following... 
     
    1. Reset the BIOS. This will ensure you are working from a clean slate and not using old memory settings or old memory training. Do not overclock the CPU. We are only working on memory. Leave every BIOS setting as close as you can to its default configuration. 
     
    2. Set the DRAM voltage to 1.40v.
     
    3. Set VCCSA & VCCIO to 1.1500v. 
     
    4. Set the primary timings to 16-20-20-40 (tCL, tRCD, tRP and tRAS).
     
    5. Set the memory speed to 3200 Mhz. 
     
    6. Save setting and reboot. The computer may reboot a few times as it trains the memory, be patient. 
     
     
     
     


     
    I tried this and it only works if I set the frequenzy to 2800MHz or lower. Same Problem.......

    If you are still within the return range for those sticks, I would send them back and go for something with looser timings. Turning off hyper-threading will give you more stability on the RAM since hyper-threading is heavily dependent on the memory.
    Rain just curious here, are you suggesting to turn off HT completely or just to test/train?

     
    Does Intel Hyper Threading Hurt Gaming Performance? I9-9900K Analysis
    http://www.redgamingtech.com/does-intel-hyper-threading-hurt-gaming-performance-i9-9900k-analysis/
     




    That is missing some important details. No mention if the RAM capacity or speed used for that test, it's rare to see people build a custom set-up and buy bare stock RAM that runs at native speeds with no XMP profile.

    My i7 9700K would hit 100% usage where FPS would take massive drops, I didn't have enough processing power in newer games @1440p. I ran into this on Call of Duty: Modern Warfare. My i7 9700K with 4266MHz CL17 RAM would get 170FPS in PUBG with high settings on 1440p and it would maybe hit 70% but once you get games with RTX and other high end graphic features, the CPU can't handle it at 1440p. Unfortunate thing was, I upgraded to a i9 9900K and my PC wouldn't boot if I tried to enable XMP on my RAM that was working with my i7 9700K. I spent more on the RAM than I did on the CPU, so I returned the i9 9900K and gave the i9 9900KS a try... it would boot with XMP but it was unstable. Returned the 9900KS and tried the 8086K that worked a little better with it, but performance took a hit since it couldn't overclock past 5GHz when my 9700K would do 5.2GHz pretty easy... but Call of Duty wouldn't even launch half the time with my i7 9700K and eventually it would max out and run so poor it was unplayable when it did work. Ended up settling on a i9 9900KS and 4x8GB 4000MHz CL18 RAM, still not as fast as my i7 9700K configuration on PUBG, but i'm also not limited on the games I can play.

    Does anybody have another Idea? I can really not think of a solution except for contacting the support again and try to rma the board again :/

    The 9th/8th Generation Intel Core Processor Family Datasheet Vol. 1, Pg. 122 Table 7-5 shows VCCSA as Min/Typ/Max = 0/1.05/1.52
     
    Pg. 123, Table 7-6 shows VCCIO as Min/Typ/Max = -/0.95/-
     
    My VCCIO/VCCSA is set respectively to 1.350V (1.376V actual)/1.350V (1.368V actual) for my RAM to run at 4133MHz..Checked in HWiNFO64.
     
    Set those voltages equally and bang them up .05V at a time all the way to max if needed.

    * Corsair Obsidian 450D Mid-Tower - Airflow Edition * ASUS ROG Maximus X Hero (Wi-Fi AC) * Intel i7-8700K (Delidded, TG Conductonaut) @ 5.2GHz* 16GB G.SKILL Trident Z 4133MHz * Crucial MX500 M.2 1TB * WD Black 500GB (x2) * Seasonic M12 II 750W * Corsair H80i V2 * EVGA GTX 760 SC * Dual-Boot Win7 Home 64-bit/Win10 Home 64-bit (Winver 1909) *

    Nothing. As soon as I go higher than 2800MHz it does not post. I used as much as 1.4V on VCCIO and VCCSA
