The FSB and clock speed are linked in Core2 processors. An E8400 is 333FSB times a 9x multiplier for 3 ghz. I overclocked mine ( In BIOS) to 450FSB times the 9x multiplier to get 4.050ghz.
so what number would I have to get in order to set the speed to 3.80Ghz ? ( I've heard that is the sweet spot for E8400's ). Also, will my cooler be enough?
