Thanks. I needed that NTP 101 lesson. So is it a stretch to try and
obtain a quality motherboard to improve the frequency offset?
Even if you were to get a higher quality crystal it would still drift
and you'd need a GPS to keep it "on time". The only thing you would
gain is that the frequency offset would change at a slower rate. As
long as NTP can "keep up" with the rate of drift you are fine.
Practically speaking I doubt you could find a better replacement
crystal of the correct frequency that would fit in the space. The
double oven crystals that are better tend be be the size of a one inch
cube, more or less and certainly not the tiny silver can on your
motherboard.

Well, I was thinking you could set the crystal off motherboard and
then just runs some wiring back to the connection points where the
crystal would sit. That way shapes and sizes wouldn't really matter.
I'm off out now but somewhere have references to projects
for doing just that. There also the plots of resultant offset
over time that show the marked improvements that were made.
