I overclocked my processor just recently and it went from duo to a quad core but my question is, what type of program is there to tell me if i have a bad core or not.

the reason i say this is because once i unlocked the quad core imo, i havent noticed that big of a increase in processing speed ect so that led me to believe that i might have a bad core. It could be that nothing is wrong and i was just expecting too much but who knows.

any suggestions on what i should do?

rofl?
