Unraid crashes when writing to HDD

[karower]

Hello,

I'm new to Unraid. For years I had a small ARM based NAS running OMV. I built a new server:

• B760M DS3H DDR4 Mainboard

• Intel I5 14500

• 64GB DDR4 RAM

• 2TB NVME Cache

• 14TB HDD

 

After a fresh install with a couple of plugins and one Docker running, I tried to copy my data to the freshly formatted HDD (xfs). But everytime Unraid crashes.

It doesn't matter wether I write data to the HDD directly or via SMB, Unraid crashes every time after a couple of minutes. Even while preclearing the HDD it crashes.
With crashing I mean, my server is not reachable within the network. After every attempt i need to hardreset my server.

While building the server, I already ran Memtest without errors.

Here is a snippet of errors within the log:

Can anyone help?

Memtest is only definitive if it finds errors, try running with just one stick of RAM, if the same try the other one.

Incredible. It was indeed one of the two sticks. Thank you very much.

I just bought the RAM and there were no Memtest errors. I wouldn't have thought of that.
