Well I create this thread to collect any useful programs and links especially for o/cers! Note that some of programs are shareware so you have to buy them after a trial period. Acknowledgements I feel grateful to many OCAU users for giving me many links and of course for their great comments. Keep it up folks! Thanks to Administrators for sticky. Stability and testing programs 1) Prime95 Test your RAM and CPU. 2) Memtest86 - Floppy version and ISO Test your RAM. 3) Toast Basically a burn-in program. 4) Super Pi Calculate π=3.14159265..... 5) PiFast Calculate π too. 6) Hot CPU Tester Pro Test CPU+RAM+chipset and burn-in CPU+RAM. 7) Stress Prime Variation on Prime95. 8) OCCT Test your CPU. 9) S&M Test RAM+CPU+PSU. 10) Stress CPU and thread is here 11) 3DMark, PCMark series 12) MemTest for Windows Allows you to run Memtest in Windows. 13) Orthos Stress Prime2004 A better version of SP2004 14) Prime95 for quad cores in French language 15) FurMark OpenGL Benchmark and Graphics Card Stability Test 16) The folding procedure 17) Intel burn test Benchmarking programs 1) 3D Mark 2001 SE 2) 3D Mark 2003 3) Sysoft Sandra 4) PC Mark series 5) Metabench 6) ATTO Hard disk benchmark. 7) HDTach 270 Hard disk benchmark. 8) Aquamark 9) FRAPS 10) WinRAR Although it is compression utility anyway it is useful for benchmarking. 11) Everest home edition 12) Sciencemark 13) wPrime System tools/Monitoring/Information 1) Motherboard Monitor Shows temperatures, voltages.
