@marco-mh You are using dual rank dimms (2Rx4) and also 4x of them. You need to lower your speed manually to 1866. If you want max performance, the max you can use is 2x 16GB, each single rank (1Rx4). There are some rare 32GB rdimms in single rank configurations, in theory you could get more speed and stability with them but I don't know if anyone tested them on an old platform such as this EPYC.

Thanks for the reply. Can you explain to me how I can set this in the BIOS?
I also carried out a MEMTEST and stopped the test when there were 9500 errors.
If I had known it would be so difficult, I would have looked for a different motherboard. I just wanted an unraid server. :-(

BMC measures 3.074 V for my battery too but the bios settings getting a reset when psu cable is removed. Maybe my board has a problem.
my settings are retained after I remove the power cable. Are the boards so old that they are out of batteries? My god, what did I buy there. Is there an alternative where I can also use my RAMs?
I made the settings in the bios. It rebooted a few times, but my URAID won't boot. I'll rewrite the stick and reinstall it. Maybe he has saved the hardware in the current installation.

You could try to further reduce the RAM speed like 800Mhz or lower. Or just use 2x DIMMs only.
The manual is only talking about 2 DIMMs, maybe 4 DIMMs are not supported at all? Use the blue slots if you only use 2 DIMMs.

Unfortunately the settings didn't help either. The same errors come.
ich hab was gefunden wo jetzt zumindest 2 DIMMs funktionieren.

I am currently trying out psu solution: 24-11-13 23-18-23 9349.jpg
No problem after 1h full load (stress command), reached 20c delta without any ventilation.
Next step is to start designing (CAD) a holder for everything that I can 3D print.
I wanna try out the PCIE port, I saw the adapter model that should work - however, what cable do people buy? Anything specific to check?
Also, the summary didn't say anything about the...SATA/PCIE port, don't remember the name, anyone tried?

85 Ohm cable for PCIe, not 100 Ohm for SAS.
That's SFF-8654-4i (SlimSAS 4i). Breakout cables to 4\*SATA work out of the box. @hmartin did a wonderful job of investigating PCIe connectivity, and found that PCIe x4 is possible, but one has to wire the SlimSAS-4i port to a PCIe slot; in my experience, a direct cable SFF-8654-4i to SFF-8639 (U.2) does NOT work.
In my opinion, this little board is most useful with 8 SATA ports for a small NAS.
Appreciate the kudos, but my investigation was for SlimSAS-8i.
SlimSAS-4i is already populated, you just need to cross-flash the EC0 BIOS to be able to configure it as PCIe (I believe there is also a modded EC1 BIOS mentioned previously in this thread).
In summary:
NVMe (PCIe x4, adapter required if you plan to use standard PCIe instead of M.2)
SlimSAS-4i (PCIe x4, cable and adapter required)
SlimSAS-8i "U2_2" (PCIe x8, cable and adapter required)
SlimSAS-8i "U2_1" (PCIe x8, cable, adapter, and soldering required)
I'm having the same issue as @ZoMbY on pages 8-9.
I've tested with Hynix 2400Mhz and Samsung 2666Mhz (2x16gb in blue slots). Connected VGA and LAN cable to IPMI.
When pressing the PSU power button the fan starts at max level and settle down after less than a minute. No VGA output on screen, no BMC info or Gigabyte logo. I can access IPMI and it shows only 1 stick of Micron RAM (2400Mhz) even if I have two sticks of different manufacturer. From the BMC console I can't poweroff the server or access the KVM console.
Does anybody have any clue what's happening ?

The Samsung sticks are pulled from an ASRock Rack motherboard with Epyc CPY where they are working properly. The Samsung sticks I just bough from a local reseller (second hand).
I even tried with 3200Mhz Kingston Fury desktop sticks which work fine in my desktop same issue. Tried with only one of the Hynix sticks in each of the blue slots, same issue.
Edit: also tried other options like removing battery, putting the CMOS connector on clear position and waiting for 10min. Tried booting without RAM, tried booting without the 8pin connector (it doesn't start the CPU fan).
Also, I can see in some pictures that people are providing only 4 pins to the 8 pin connector, I'm using standard ATX 8pin connector. May this be an issue ?

This doesn't matter.
Yes, because the board is 12V powered. You're essentially providing it with only BMC power (5VSB + control signals) by removing the 12V EPS power.
The inventory in the BMC is only updated after a successful POST. This is why it isn't displaying the RAM you have installed.
DRAM training takes a very long time, multiple minutes after changing the installed RAM (Google "Ryzen DRAM training" to get an idea). I have also found that sometimes it helps to hold the power button until the board powers off, then power it up again and wait for DRAM training.
Additionally with the default settings, BIOS will wait for 2 minutes for the BMC to boot, so you also need to ensure the BMC is fully booted before powering up the x86.
Provide some screenshots. What can you do? Have you tried factory resetting the BMC from the web management interface?
