BTRFS error on new server

[b00]

Hello guys,

 

I have built together an unraid server- everything except the drives and RAM is new. It consists of three HDD's and one NVMe for cache. Today I started moving data (movies) from a PC to server. When I started moving the data from cache to HDD's I found out a bunch of these errors in the logs:

I'm not sure what to do with it. Does it mean that my new NVMe is failing? Can I test it somehow? 

Should I delete all the data transferred from cache to hdd and transfer them again?

I'm not using any docker or apps yet (I've only used the preclear plugin on the hdd's on different pc)

Checksum errors mean btrfs is detecting data corruption, start by running memtest.

Wow, @JorgeB it looks You were right!
I would never thought that it was the RAM problem. Since most of my hardware is re-used (motherboard, CPU, PSU) i need to double check if the problem is the memory (which is new) or a CPU/mobo. 
Thanks for pointing me into that direction.
