How to Stress Test your CPU for Stability and Heat Problems


1. Download the appropriate 32-bit or 64-bit Windows version of Prime95 from this link: Free Software - GIMPS

You can skip down to step 2 on that page; it is not necessary to register, if all you want to do is torture test.

2. Run the Prime95.exe file. If the UAC warning appears, click "Yes" to allow it.

3. Select "Just Stress Testing" in the first window that appears.

4. Select "Small FFTs", or whatever tests someone asks you to run. Prime95 will automatically select the maximum number of threads reported by Windows in the "Number of threads to run" box.

5. Keep an eye on your temperatures, and stop the test if the machine starts to overheat.

6. Leave the test running for up to 6 hours, unless errors occur sooner. Errors will show up by one or more of the workers stopping.

Note Great Gurus  Note
Gurus should know that as with all hardware tests, Prime95 is not fail-safe. If the CPU passes for 6 hours with no errors, it is most likely to be stable. Unfortunately, it sometimes makes mistakes and gives a clean bill of health to a faulty CPU.
