We used Prime95 as the final, most sensitive test. This is actually part of a distributed computing project to search for very large prime numbers. However, it's grown to be widely regarded as one of the most sensitive stability-testing tools available. In recognition of this usage, the authors have included a "Torture Test" mode which runs intensive numerical calculations and compares the calculated result with known correct results. If a difference is found, the program aborts and informs you of the error.
