Depends on what you mean overclock. Modify something to go faster?? Then if so that would be my car, motorcylce, hmm....model rockets, straped 4 c6-7's on one before and that baby took off into orbit!! LOL..went sooo high, it was cool. What i havent done is OC a computer, I did oc the FSB to 133mhz though, not a cpu though.
