Okay, I'll have to resign myself to keeping my 128GB ram at 3000mhz

If it helps, I have a C8F and I am stable with my 4x8Gb 4000Mhz downclocked to 3800Mhz and bios 3101. To reach stability I had to change the dram and vdd voltages as per recommended suggestions from Ryzen DRAM Calculator, but nothing else.

what voltages did you use I tried the bios 2311 2702 3003 raising the vsoc and dram a bit without results but I also have 128 gb of ram

As I said, I followed religiously the recommended settings for my dram suggested by the Ryzen DRAM calculator: https://www.guru3d.com/files-details/download-ryzen-dram-calculator.html
First I used the freeware version of the Thaiphoon Burner to get the specifications for my DRAM and generate the DRAM report : http://www.softnology.biz/files.html
Then I imported the report into the DRAM calculator ( following these steps: https://www.reddit.com/r/Amd/comments/cw3cn0/psa_use_thaiphoon_to_exportimport_your_xmp/ ) which gave me the clocks to set in the bios, and in my case suggested to set the voltages like these:
SOC Voltage: 1.125
VDDG CCD Voltage: 1.05
VDDG IOD Voltage: 1.05
cLDO VDDP Voltage: 0.950
It also gave the exact termination voltages and similar settings.
Before these changes, I was getting sudden reboots while idling on windows, now it is stable since a couple days with bios 3101. I understand that we should not have to do this kind of tinkering to have the DRAM working as intended, but this may work for you too anyway.

Well your module is not listed as compatible.
Listing "kits" on QVL lists is generally pretty useless, It's much more helpful for any company to list specific module numbers for compatibility purposes as often the same "kit" can be from a different memory manufacture i.e Samsung, Hynix or Micron and on top of that have slight differences which result in stability issues, In your case not being able to run at the rated speed.

the chip of the kit tested by asus is Micron as in my ram kit .. everything corresponds and if they have certified it, there must be a reason otherwise it would not appear in the vendor list
