Hopefully you were joking. Over 100ppm (parts per million) is pretty
bad. The only board I ever had that was worse than that is the current
one based on the AMD chipset. It turns out it has a "spread spectrum"
modulation for the south-bridge chip and that causes quite a bit of
frequency offset. Turning that off fixes things (but I assume annoys
the FCC.)

Your wrist is a wonderful temperature controlled device to strap a
crystal to. Wristwatches have it easy.
