This server likely had a setting enabled to perform a full test of the memory on boot.

I'm not sure why server vendors do this (I've never once in my career seen that test catch anything), but the boot times have nothing to do with ECC. My Ryzen 9 3900X-powered PC with 64 GB of ECC boots in a few seconds.

> ECC RAM is supposed to be serving services that requires extremely high RAS (Reliability, Availability and Serviceability). Any normal DDR4 RAM out here is already having a good enough RAS for a relatively long time.

Without the ability to detect errors, how do you know it's good enough?
