Has anyone actually overclocked an A600?

It is pointless to do this. You get a 5% speed increase. Just adding fast ram to the Amiga gives you a 10% speed increase.

As an alternative, has anyone tried adding faster RAM in chip and fast RAM?
Could you then raise the clock speed a little to take advantage of it?
btw, With the specs of the 68000 available could you add some external cache RAM to and run it at 14mhz or 28mhz. That sound like an easy project for someone with a little experience.

I modified my newly acquired A600, connected the 14mhz output from agnus to the clock input on the 68000 (after cutting a track)

did nothing. no video output at all.

There are several reasons: Either the CPU did not like the higher clock rate. Or one of the timings are out. A simple one, but check the track for continuity.
