We’re in agreement.

I think we diverge on ‘making it go away in my book’.

When you’re the one having to debug all these bizarre things ( there were real money numbers involved so these things mattered ), over millions of jobs every day , rare events with low probability don’t disappear - they just happen and take time to diagnose and fix.

So in my book ecc improves the situation, but I still had to deal with bad dimms, and ecc wasn’t enough. We used not to see these issues because we already had too many software bugs, but as we got increasingly reliable, hardware issues slowly became a problem, just like compiler bugs or other elements of the chain usually considered reliable.

I fully agree that there are lots of other cases where this doesn’t matter and ecc is good enough.

Thanks for taking the time to reply !
