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 :/

Do you have the means to try another CPU or different memory? You already replaced the board once. I'd think it would be unlikely you would get another board with the exact same problem.
 
I'd be careful exceeding 1.2500v on IO and SA for long term use. I went as high as 1.500v for SA when I was trying to get 4400Mhz CL 19 to work but its not a setting I'd use long term. I think its much better to drop down to say 4266Mhz and go for CL 16 then hammer the SA with voltage to force 4400Mhz. 

I used the exact same memory and cpu on a different motherboard and everything worked perfectly. I don't see why it should not work on this one

Yeah but... overclocking and voltage will degrade your memory sticks. I was able to push my kits too, but over about 3-4 months everything became unstable because of degradation that can occur in the memory or the memory controller. You are probably better off running an RMA on the RAM, unless you have access to your previous motherboard to make sure it still works.

I used a Z390 Phantom ITX. And between my first Z390 Dark and the RMA Board i used the phantom itx and it worked perfectly. 

The Dark has a better memory QVL's than the Phantom, it should handle your memory no problem.  Test component by component, then rma again.
 
Maybe order some fast loose 2x8gb b-die from Amazon and try that out.

Were your F4-3200C14D-16GTZR bought as a matched pair or separately?  Like I said early in the thread, that's not on the EVGA QVL, only the ultra high bin 64gb kit is.
 
The actual bin and chips make a big difference.  For example, I had a cheaper G.Skill 2x16 3000CL16 kit that ran on my MSI MB but wasn't stable and wasn't on the QVL.  I made the mistake of getting another of the same kit for 64GB, I had to down clock it to 2666CL16 to get it somewhat stable, but it would still WHEA error crash occasionally.  Really did some research and upgraded to 2x16 4000CL19 b-die, which as been stable for the last 3 months, MSI boards have great 2 channel memory support with the right ram.
 
Have you done a readout of your ram with Thaiphoon Burner?  Is it actually B-die?
 
The 3200CL16 you tried is crap ram.  I'm talking about something like 3600CL17 or 4000CL19 b-die.
 
The 2800 10 12 12 28 you're running is very low latency, so the combo is highly performant at certain settings.  But MB ram trace layouts are a tricky thing, they don't always play nice with certain settings.  It may be that the DARK just falls on it's face around 3000-3200mhz and is optimized to run much higher.
 
 
 
 

I am currently running 2 32GB modules from a Corsair at 3000mhz for my Z390 setup.

Yeah, pretty loose timings: 16-20-20-38-2 (tCAS-tRC-tRP-tRAS-tCR)
 
Might be worth trying for OP though.

I never even touch the settings at all. All I do is enable the profile and leave it at that.

I have a similar situation with you. The memory I use is EVGA 3200 C16. The frequency can be adjusted by using it alone, but the two memory frequencies cannot be modified at all. I changed them to Z270 FTWK to use XMP. I found that although their SN numbers are a bit far away, because I have four such memories, I never thought that the production date would affect compatibility, you can also refer

is this for me this answer?
i can't get well what are you tring to say, what i know is that on my previous asus z390, at least XMP worked well, with this bord not

Not sure what is causing your issue, but I run a GSkill 4500MHz 2x8 GB kit. XMP2, Manual, Auto, no problems.
 
Maybe you need better DIMMs?

maybe, but still i can't find the dram:fsb ratio
 
i need to lower this 1:42 but dunno how

I allready used a different kit. 3200MHz CL16. It doesn't matter how I set the timings voltage etc. As soon as i go over 2800MHz the system will not post with both memry kits. 
This problem only happens in dual channel mode. In single channel I can easily push 4000 cl17

On my Aorus Master, I also cannot run higher than 2800 mhz if I *disable* XMP and set the RAM settings to 3200 mhz manually.  It just fails to train and sets it to 2800 mhz.
But if I use XMP, it trains fine.  It's the 3200C14D-32GTZR kit (2x16 GB).
 
I suspect one of two things:
1) RMA the CPU (do this last)
2) Buy a RAM kit on the motherboard QVL.
3) Set the subtimings manually.  Main timings won't help you.
 
XMP is only responsible for setting the primary timings and speed.  When RAM is on the board QVL, the board will set certain sub-timings for you for that memory when it is installed.
I suspect changing the subtimings will make the RAM work unless the CPU is defective.
 
I would start with TWTR_L and TWTR_S, which are related directly to TWRRD_sg and TWRRD_dg.  I don't know what values to use, but you can try tWTR_L=6 and tWTR_S=5.  Those will set values in TWRRD sg and dg if those are on auto.  I do not know about the others.
 
Set tWCL equal to tCAS (tCL) and set tWR=tWCL and tRTP = 1/2 tWR.
The four TRDWR values can be set to 2 lower than tCAS safely.  I can't help more as I am not experienced with RAM.
 

 
According to G.Skill support, just because it's on the QVL list does not mean that it works with every CPU configuration. In my case, I had a 4266MHz CL17 kit that worked with XMP enabled on a i7 9700K, after upgrading from a RTX 2080 to a RTX 2080Ti the XMP profile was no longer stable and my CPU just kept hitting 100% load quickly in newer games. I tried to upgrade to an i9 9900K thinking it was maybe the memory controller on the CPU or maybe I just needed hyper-threading. The kit wouldn't even boot with the i9 9900K. I figured the i9 9900KS with the extra power allowance might do better and it did but with a lot of soft crashes that were also occurring in the i7 9700K. I found an i7 8086K that could handle the CPU load but it couldn't keep up in frequency so it ended up taking significant performance hits on games that didn't support ray tracing. After dedicating many hours over a few months, running through different scenarios and combinations I gave up on troubleshooting and just bought something a little slower... 3600MHz CL18 seems to be the perfect spot for RAM, I don't really notice a difference going from that to my 4000MHz CL18 kit I have now... but I didn't buy it for that as much as I did for the aesthetics and the newer LED configuration.

I tried a few things and I still can not get it to work. 
 
Can somebody please write down a profile that is +2800MHz including timings and voltages that should work 100% with any B-die. 
 
Maybe I just used the wrong timing - voltage combination or similar. 
 
I would highly apprechiate any help as otherwhise I need to contact support again or sell the board (I really don't wanna do that).

Thank you for the profile. But thats a really good OC. 
 
But I need a profile (around 3000MHz) just to test if I can run my memory above 2800MHz. Which is currently not possible.
 
I litereally tried everything I saw on any z390 dark memory OC video and what people suggested here.
 
In my opnion it is still a BIOS or Hardware issue on the motherboard side as I can not understand why 2 different ram kits are not able to run at 2800MHz+

If frequency is what you are trying to get, i'd start with native frequency timings... Native 3200MHz RAM runs at 22-22-22-52. If you can get it to boot with that profile, you should be able to tighten timings from there.

Doesn't boot

Did you ever try some better ram?
