We’d be seeing weird bit flips and file corruption all over the place if this was even close to being true. I have ECC systems that will report the number of errors detected and corrected. Still waiting to see any errors on my main machine with 64GB of RAM. At server farm scale, the majority of memory errors come from a very small number of faulty memory sticks. It’s not an even distribution of errors across all memory.
