Planning to overclock your Amiga? Looking for a variety of crystals?

I wanna overclock a 3640 with 25 Mhz to at least 33 Mhz. But I am actually bidding on a kind of Speedmaker device that allows to change the Mhz from 0,5 to 120 ... easy for experimenting  :-)

But as always, I haven´t got it until I have won it  :-)

Seems to make sense, although I would not wanna try to overclock a standard 14,2 Mhz A1200 t4 42 Mhz ... unless somebody tells me it is possible
How fast can you overclock an 68010 by the way
