what do you use for burn in test ?

Question

what do you use for burn in test ? and for how long do you run it? can you be %100 sure machine is stable if it doesn't crash while a burnittest?

Answer 1

There is no guarantee that burn-in tests reproduce fault conditions that could give rise to a crash. These can be caused by an infinite combination of such as instruction sequences, data patterns and timing quirks. Recognised burn-in test are generally those that create maximum CPU temperature, but this also depends on room temperature. All they generally show is that the CPU can run at higher temperatures and might not stress caches, main memory, graphics and other peripherals.

My site has been referred to as a source but particular documents are:

In these cases, maximum CPU temperature was reached within 20 minutes. Best option would be a series of different tests, as we did in the old days on acceptance testing of 100s of UK Government computers (for 15 minutes each test). Then early life failures were significant and that is what burn-in tests are really about.

Answer 2

Leave it running for 24 hours with PCMark demo running.
If you are unfamiliar with PCmark, its a benchmarking utility made by a company called futuremark.

Answer 3

first run memtest on it overnight ... if it passes without error thats good ... then run prime95 on it ... if you have a dualcore run two instances of prime95 - one on each core ... if it runs prime overnight with no errors then ur good ...
