  1. I use identical case ( not 4U ), they come with SuperRed fan and I replace all to Arctic due to noise issue. If you need cooling with SuperRed fan, you can direct connect it to backplane ( loss monitoring and control by mainboard ), there should have two jumper to control ( 4 level ) the speed.
  2. Don't need reinstall, usually some plugin need reconfig, i.e. System temp due to hardware change. Ryzen 2700 or 2700x also a good choice for more CPU horse power except you really need 2 GPU.
  3. No much reason for non-K, but extra heatsink cost also need consider ( depends on stock or not ).
  4. I change the SFP+ that resolve X520 link flap issue, the problem one also same brand Unicaca, just different model.
  5. BIOS have ACS function under AMD CBS, you may try enable that.
  6. The backplane was raw type have 6 minSAS port or 24 SATA port ? I quick check all SC846 was SAS expander blackplane type, so I don't understand what means about 15 drive were connect to LSI HBA, in general all disks would detect under same LSI HBA.
  7. It is sda, does you boot OS by this disk ? Pls don't boot OS by this disk and try plug the SATA link after boot up.
  8. Pls try other controller i.e. onboard. And also try plug in SATA connector after OS bootup.
  9. I boot Threadripper into baremetel Windows10, the iperf3 result really poor and unstable ( no any hardware change ), some help by NIC parameter tuning. Finally, my NIC ( X520) haven't NUMA node assignment support, so I set RSS from default 8 -> 4 -> 1 or interruption moderation disabled then got a good result, but still slightly unstable.
  10. Could you make test on single CPU or other platform in both side, even Windows or Unraid. I make some test on Threadripper platform and setting with CPU pinning, the result different was small.

Anyway I need fix it later. What iperf3 version you are running ? I notice you haven't "Retr" column.

    i219v issue

    i219v were common on Intel platform and I haven't problem too. Does mainboard BIOS already update ? Your provide link have two solution which seems can fix it in hardware level. https://superuser.com/questions/1104537/how-to-repair-the-checksum-of-the-non-volatile-memory-nvm-of-intel-ethernet-co/1106641#1106641 1. Write NVM Checksum word using ethtool 2. attempt to boot over the network with UEFI (IPv4)
  12. 9400-16i also fine and it support NVMe, but this won't have performance gain in your case too. There are many different kind LSI card, not all work with Unraid. In fact, most pepople with go with 8i card i.e. 9211 or 9207, because it cheaper a lot. You could connect SSD to mainboard.
  13. SMB transfer 1.1GB/s max ( a 23GB file ), so it higher then iperf result.
