lm_sensors when misused can also kill hardware by "probing" registers the wrong way when looking for sensors. https://wiki.archlinux.org/index.php/lm_sensors https://wiki.archlinux.org/index.php/lm_sensors Probing is different than testing, though, and people don't expect a general system memory testing tool to kill hardware (whereas lm_sensors has all sorts of warnings and takes the safest route possible by default). A tool that is designed to test general system RAM should not be touching memory-mapped I/O devices, and it's up to that tool to avoid them.
