The reason such a high amount of stability is recommended is because of silent data corruption being a possibility in the background, regardless of what you run on a normal day of PC usage. For example, the day you boot the computer and something in Windows is suddenly broken and it costs you a reinstall. Things of this nature. That said, 12 hours of Prime95 with Rounding Error Checking enabled is more than enough for most people. IBT also can determine processor stability, but not so much on the system bus or RAM/IMC.
The ultimate test is Folding@Home for a couple days, as this can even make "stable" overclocks crack under the strain. My chip needs 1.512 to fold, but eats Prime95 and IBT at 1.475.
That said, no chip run outside factory specifications' blanket can ever be 100% stable in all conditions, so as long as it's working for you, that's about as good as you can get.
