    So, i had a few memtest runs - ECC errors only happening while Test #0 and Test #1.
    The tests i did:
    • all 4 ram modules
    • only 2 ram modules in dual channel configuration (first A, then B)
    • only one ram module, tried all ram slots
    Example results:
    All modules:

    The above errors are happening for all modules, regardless in which slot they are seated. I think the problem is not the RAM, maybe the CPU / Mainboard is fried.

    Any ideas ?

    There is a known BIOS bug with i3200 chipsets
    https://bugzilla.redhat.com/show_bug.cgi?id=564274
    Final comment was, "Some i3210 BIOSes have problems enabling the hardware checks at the MCU. On those hardware, customers should try to disable Quickboot and / or "Memory Remap Feature" or to disable EDAC drivers.

    This isn't the exact model you have, but behaviour sounds similar.

      Hello David,

      thanks for your quick reply. The 4x runs without #13 Hammer Test finished without errors. After that, i disabled Fastboot and Memory Remap in BIOS and tried a short run of Test #0 + #1 - the same errors are still happening. So i am quite uncertain about the relevance for the stable operation of the system. The behaviour sounds similar to the bug report, but the server is now around three years old and i never noticed these errors before - which is a bit strange.

        Sorry for doubleposting, but i can't edit the previous post anymore.

        I replaced the PSU and the CMOS battery on the failed system, then i booted it with all drives disconnected. The ecc errros are still appearing. My workstation supports ECC RAM (Ryzen 5950x), so i switched the RAM between my workstation and the server. On the workstation with the "failed" ram from the server there are so far no errors, the non-ecc (workstation) ram in the server is testing fine currently, too. So i am just more confused. Probably the CPU or the RAM controller on the server may be faulty. Or an incompabitility between the servers ram and bios, but it would be strange after three years of operation without problems...
