> ...get one of few AMD motherboards with matching CPUs and overpriced RAM... I mean, if you want a _guarantee_, then sure, get one of those certified-for-ECC motherboards. But, like, as far as I know, going _at least_ far back as the Phenom II (released in 2008) AMD desktop processors have always supported ECC RAM. And -as far as I know- ASUS motherboards for said processors have always supported dropping in ECC RAM (and Linux and memtest and friends have always agreed that ECC was enabled and functioning in such a system).
