System stressing and benchmarking tool for overclockers

System Stability Tester attempts to test the PC stability by calculating up to 128 millions of Pi digits.

System Stability Tester supports multiple calculation algorithms including: The Quadratic Convergence of Borwein and Gauss-Legendre, the algorithm SuperPi uses. The testing process includes the creation of two or more threads. After each step of the calculation, the results of all the threads are compared. Any differences between them are reported.

Features and highlights

  • Calculate up to 128 million digits of Pi
  • Create up to 32 threads
  • Recognize the CPU model, manufacturer and operational frequency
  • Compare the calculation results of all the threads after each step and issue a warning if something went wrong
  • Run continuously for up to 50 turns and log the results after each step and each turn
  • Record the calculated digits of Pi in a human readable text file
  • Single threaded calculation of Pi for benchmarking, similar to the well know SuperPi benchmark
  • Checksum validation over the result
  • Provides graphical and command line user interfaces
