so, in 775 processors, the multi was fixed and you raised the fsb.
in a k series processor, you raise the multi and generally leave the bclock (analogous to the fsb) alone.
also, and this will probably be controversial, turn off turbo boost.
The thing that really intimidates me atm is actually overclocking the new graphics cards. They seem to change clockspeeds all the time depending on factors you can't control.
