Prime95 small FFT will help you identify CPU related errors
Prime95 blend, 6 to 12h will help you determine overall system stability
Intelburn, I don't use it. Instead, OCCT 3.0 has a test called Linpack which is the same test as INtelBurn. I use this Linpack test for a few minutes only to see how my cooling system is working. Running it 5 minutes is enough!
I consider my system stable if I can run 6h of Prime95 blend + 2h of OCCT + PCMark05 benchmark + at least one day of regular use
