I don't agree with the suggestion to disable the spread spectrum
stuff. It's there for a reason. Effectively, your CPU will run
slightly slower. I haven't seen anything published to indicate
that the speed is sufficiently less stable so that ntpd will notice.
It will be different than the nominal value, but that's not a problem.
It would be fun to see if you can measure it.
If you like that sort of stuff, you should also read:
