I'm using my CPU, memory and board with the default, spec-defined voltages and frequencies. Yet if I run Memtest 5.01 (which installs alongside my Linux Mint 18) in SMP mode, my machine hangs at some point in the beginning of test #5. I can complete a pass in single-core mode; and I tried about 30 minutes of stress-ng.
Now, this is a new CPU, memory and board, so while it's possible there's some issue with them, it's not very likely. On the other hand, I have read here and there that MemTest+5.01 might fail. Also, I just found the 5.01 Changelog, which says (emphasis mine):
- Corrected bugs, bugs and more bugs (some could remain)
... and this certainly does not expire confidence.
I don't want to exceed the scope of this site, but - how should I proceed? That is, should I try to get some alternative memory torture-tester and run that? Should I assume it's a bug? I'm going to write the MemTest author anyway but perhaps other people can share a similar experience.
