As many are asking: What if I've already installed one of the not-so-EZ clocks and removed parts from my motherboard?

Yes replacing removed surface mount parts especially can evoke some or all of pain, fear and loathing.

If you have already installed clocks the "hard way" we recommend using "XO" output and wiring the clock signal directly to the clock pin, basically the same way you have previously connected the clock.

But just soldering in the XTal adapter in the place of the original crystal with non of the removed parts replaced will be fine too.
