That's is a good overclock and keeps it completely on the safe side. As far as running 1.45v, "Ha", I have ran my chip with 1.65v. Intel's white papers put the limit at 1.55v, so 1.45v is not a stretch. More than likely you would need to go to 1.47v or 1.48v to get the extra 10Mhz FSB speed. Whether it's worth the extra heat is up to you. Also, keep in mind that as soon as your chip goes under load you will get Vdroop unless your board has load line calibration or has been modified. Vdroop, drops your voltage down to prevent the voltage from jumping to high above the set voltage when you come off of load. My point is, although you are putting your voltage at 1.47v, in reality, under load it will be much less depending on your Vdroop.

At any rate, a 50% overclock is nothing to sneeze at,
