Early in my career I had to deal with similar issues, but with cellular networking equipment. I do think it's one of those things where if you have a way to detect the bit flips it happens way more than you think... but most people can't detect them and mostly get lucky enough that they never see an impact when it does happen.
But because we had some equipment that would checksum itself we were able to see the bit flips happen, probably every 1-3 weeks or so I'd find a bit flip.
- immibis 2y agoI literally just built a new workstation with 256GB of DDR5 ECC memory and had two detected bitflips within the first hour. It's likely that something's off with the timings or voltages, then, but... if I didn't have ECC, didn't have an AMD processor that generates MCEs Linux can decode, or didn't have a kernel set to log MCEs, would I know about them? Definitely not.
