I believe there was data that with 64GB of RAM you can expect at least a single bit error or two a month. Thus ECC would be super helpful to those that expect that most of the 64GB will be filled with bits that shouldn't be changed. This article by a system integrator is a pretty decent data point: https://www.pugetsystems.com/labs/articles/Advantages-of-ECC-Memory-520/ https://www.pugetsystems.com/labs/articles/Advantages-of-ECC...

>>>I believe there was data that with 64GB of RAM you can expect at least a single bit error or two a month. But this would be if you were using 64GB nonstop for a month, which is quite a bit rarer than just having 64GB. And certain filesystems (ZFS, Btrfs) and most databases have software checksumming functionality to detect bitrot. Not to say ECC isn't useful or multiple layers of protection aren't prudent, just that the problem it solves is something you're unlikely to encounter below datacenter scale.
