I have 128 GB of non-ecc memory in my notebook, never detected a single error, and has been on 24/7 for more than 4 years.
Unless you live over 4000 meters over the sea level, like to compile while flying or live close to an unshielded nuclear reactor, you don't need ECC.
And most memory problems you can fix by better cooling, and better shielding.

- aortega 4y agoI know that I never detected them. Also it never crashed nor malfunctioned in any way (thanks in part to Linux), so any undetected error didn't caused any problem.
- russdill 4y agoThere's been plenty of studies they measure bit flips in memory. If you really wanted to measure, you'd find them without much difficulty. Yes though, when you have gobs of memory, you're unlikely to see the effects of bit flips. That's not the same at them not occuring.
- mech4bg 4y agoMy 4 year old Mac Mini had been showing some flakiness and finally I got an error about "hash mismatch detected on volume" - ran memtest and sure enough the RAM had gone bad. I rely on this machine for all my media, backups, etc, goodness knows what data I may have lost while the RAM was bad. It's a moderately common problem, found plenty of people with the same issue.
- PragmaticPulp 4y agoI’ve had 128GB of ECC memory with error reporting. Never logged a bit flip as far as I can tell. Memory errors are heavily concentrated to bad modules. They’re not evenly distributed across all RAM. Always test the stability of your memory when doing a new build.
