Prime95 is a software download which searches for very large prime numbers. It has become extremely popular among PC enthusiasts and overclockers as a stability testing utility. It currently includes a "Torture Test" mode designed specifically for testing PC subsystems for errors in order to help ensure the correct operation of Prime95 on that system, but can also be used to stress test a PC.

People who are overclocking their system may use the torture test as an indication of the stability of their system.

Version 28.9 is a freeware program which does not have restrictions and it's free so it doesn't cost anything.
