Since I got my board I experience issues and it seems that I have found the culprit.
Running memtester, the output states:

I need help figuring out which of the memory modules is broken, so I can buy a replacement part and exchange the BGA.
The issues I have range from random kernel panics to freezes to segfaults, so I am quite certain the issue actually is memory related.
