Faulty Memory?

[Spectrum 0]

Hi,

i was facing some crashes (system and individual apps) with my brand new Tinker Board 2.  At first i thougt that maybe my 12V power supply was too weak but even a 19 V /60 W adapter did not really help. I ran the preinstalled memtester 4.3.0 and got the following results (no matter how much memory is tested). Is this most certainly an hardware issue (bad ram) that can not be fixed or is there anything i can do about it (maybe changing memory settings or trying other memory testing software - maybe memtester is bugged)? Occasionally no errors are found which gives me some hope. 🤔  A faulty brand new board would be a nightmare since return is not so easy or may be even impossible for me...

Thanks in adavance. 🙏

Best regards
