Utility to test for faulty memory subsystem

A user-space utility for testing the memory subsystem for faults. It is 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.

The original source was by Simon Kirby sim@stormix.com. The program has been rewritten by Charles Cazabon and many additional tests were added to help catch borderline memory. He also rewrote the original tests which catch mainly memory bits which are stuck permanently high or low so that they run approximately an order of magnitude faster.
