'prime stable'

[builder22]

was using superpi, always passed the tests with that
now trying prime, obviously a harder test as it failed after 3 mins so have had to mess with settings
but what is 'prime stable' ?
theres the benchmark test and the torture test, also the settings in prferences, which options do I choose for a reliable test ?
thanks
