Now I'm wondering how FreeBSD handles damaged RAM differently, and the speed hit it takes for doing so.

- toast0 6y agoTo my knowledge, FreeBSD doesn't have anything specific here, it was probably just luck in where the broken addresses fell and how they were used. These days FreeBSD and Linux both have provisions to avoid addresses you know are bad, if you tell them at boot (and if you don't need those addresses to boot). I'm pretty sure I've read that Solaris has provisions to stop using bad addresses detected at runtime, but it needs ECC or similar to detect the badness.
