The PG does not officially support nor oppose overclocking, but be aware that any instability which causes WUs to error-out during processing is detrimental to the project, and overclocking makes it more difficult to identify any issues with particular WUs or FAH clients. Folding@home often stresses hardware further than many popular stability testers, such as Prime95. For this reason, we recommend StressCPU. Since it’s based on Gromacs – the main software used for FAH’s calculations – it’s one of the most accurate stability tester for an overclocked machine aimed at stable folding. There’s no rule about how long you should run it, but the longer, the better. There is an option (-t hh:mm:ss) to run the program for a limited period. If you don’t add this option, it will run until it fails, or you press CTRL+C to manually end it. Please let your computer’s temperatures stabilize when testing; this takes longer with watercooled systems. Please see this Forum thread for more information.
Use FAHBench and MemtestG80 or MemtestCLÂ for GPU stability testing.
