Just out of curiosity, how long is your scope probe ground lead?

At these freqs it needs to be less than 2 inches max (better shorter) or it
will show ringing that isn't really there.

As for fanout, you can always try a clock distribution system - 3 or 4
inverters, inputs from your clock source, outputs to different destinations.

Good luck!
