I.. would probably have done that before concluding I didn't have any need for it. Even just do a quick one-off mcelog run to see what events have happened recently - you don't have to do some big statistical analysis. I'd estimate about half the machines I've used with ECC have had at least one correction a year, maybe a quarter had one every few months. I've seen one-off weird bursts that never happen again, and I've had quite a few cases where ongoing corrections have indicated a DIMM needed reseating. An actual blatantly faulty DIMM's been quite rare.
