If you drive the X1 (on most 805x-types) input with a crystal oscillator rather than simply tying a crystal between the two Xn pins, and adding the load caps to GND, you'll get better results

if all you are driving is the actual uC, there is no need whatsoever for an external oscillator.

Doesn't the original post suggest otherwise...?
