System Stability Tester is a free open source system stressing and benchmarking utility, specifically designed for overclocker, that tests the system’s stability by calculating up to 128 million of pi digits.
You have two choices to use the tool, either stress test mode or benchmark mode when 2 ore more threads are selected. While the stress test mode is used to verify if the system generates any calculation errors, the benchmark mode can be used to compare between systems.
You can also choose how many PI digits, turns, and number of threads to be used during the test. Increasing either of these numbers will significantly increase the time spent on the test. Selecting very high number will be resulting an extreme stress testing to your system. So save all your work first before doing this.
So far System Stability Tester only implemented two algorithms, Quadratic Convergence of Borwein and Gauss-Legendre, both used by SuperPI utility, even though the tool itself supports multiple calculation algorithms.
The tool is written in C++ program, and works on a wide range of platform, including Linux, Unix, Solaris, HP UX, Mac OS X, Win 32 and 64-bit operating systems. Both installation binary and portable versions are available. Just go to the download page, and pick the proper version for the operating system you will be using.
If you are a computer fan loving to manipulate your core processor, you probably would want to use this tool to benchmark the processor before stressing the power out of it.
