memtester
A userspace utility for testing the memory subsystem for faults. It's portable and should compile and work on any 32- or 64-bit Unix-like system. (Yes, even weird, proprietary Unices, and even Mac OS X.) For hardware developers, memtester can be told to test memory starting at a particular physical address as of memtester version 4.1.0.

It'll run fine from the build directory, and you can read the man page from there with `man ./memtester.8`. The `/usr/local/` part is configurable in the Makefile, too.
