Welcome to overclocking
re: your above question...its all not that easy becasue a CPU is a complex thing..sorry to sound like a dumba$$ knowitall

But you never know WHEN and how your CPU with WHICH application/game calculates right. Some calculations (eg. FFP operations) may put more load on the CPU than other instructions, therefore people use Prime which uses the CPU to its maximum to test stability.
ALso..the "failed" overclock may not bew visible to YOU...a failed OC does not necessarely mean your comp crashes - often it just "calculates wong"...eg. prime/seti...etc...generate wrong results.
Same btw applies to graphic card overclocking - the card itself seems like it renders ok.....but the shader code (eg. if FFP shader code is used) fails to caclulate right which can lead to more or less apparent "errors", some visible, some not, some only after someone told you so and often only for certain shadfer-routines.
You decide whether you want to gamble....but in my opinion it is just NOT worth it. If i spend a grand or so on a new PC then i expect at least it works right in every aspect..just to avoid ANY future problems....i dont think that a 0.5 percent performance gain legitimates a NON 100% working CPU...and, as you see in recent titles (eg. doom3)...these are the titles where, all of a sudden, people realize they need to clock down....because these titles demand more than other titles which dont use the CPU/GPU to its fullest.
Edit: its FPP (floating point precision, AFAIK...not FFP..sorry..long day
