That's an interesting question. As far as I know, it isn't accessible. There may be testing tools that can be run on a live Linux system. For machines with ECC RAM, there is mcelog, which reports memory errors to syslog. My desktop machine has ECC RAM, but my laptop doesn't. Some commentators such as Russell Coker argue that it's worth buying desktop machines with ECC memory, and he notes that they're available relatively inexpensively (new or used).
