There is also ports/sysutils/memtest that may be run from multiuser if one manages to build it with broken memory :-) Or it's possible to install a package. One problem with running such application with OS loaded is that kernel places strict limit to amount of memory that user-level application may lock. There is a PR with a patch that allows to raise the limit so memtest could test most part of free memory: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=kern/114654 Eugene Grosbein
