CPU Burn-in v1.01 by Michal Mienik is the ultimate stability testing tool for overclockers. The program heats up any x86 CPU to the maximum possible operating temperature that is achievable by using ordinary software. This allows the user to adjust the CPU speed up to the practical maximum while still being sure that stability is achieved even under the most stressful conditions. The program continuously monitors for erroneous calculations and errors ensuring the CPU does not generate errors during calculations performed under overclocking conditions.

CPU Burn-in constantly cycles FPU intensive functions for a user specified period of time. The resultant calculations are constantly checked for data integrity. If the program detects erroneous data the user is immediately informed. Applications such as SETI@home and Distributed.Net perform no such data checking. The user must rely on those programs to crash or the system to hang before a problem can be noticed.
