Given the number of computers now it's practically a certainty. One of the big challenges with diagnosing non-ECC RAM is that you can't directly measure it so you're left trying to eliminate issues elsewhere first and measuring symptoms or stress testing to determine if RAM is the most likely failure, meanwhile the system literally can't remember correctly. And that's if you're actively looking to diagnose, as opposed to accepting some gremlin in the machine.
