Has anyone actually overclocked an A600?

Been looking in to this, and it seems the issue with the A500 and overclocking the stock cpu, is that the "E-clock" signal that feeds other parts on the motherboard comes from the CPU, so if you double the speed of the cpu, this frequency also doubles.

However, the "E-clock" on the A600 is generated by the Gayle chip, so the E output from the CPU doesn't go anywhere, meaning if its the wrong frequency, it shouldn't matter.

BUT! I can't actually find any conclusive answer as to whether or not it will even work....

You can overclock a Sega Mega Drive using a 10Mhz crystal oscillator, feeding the signal into pin 15 (clock in) on the cpu, and this works fine on 99.9% of machines...

So, can this method potentially work on an A600? can I take the 14Mhz output from the Agnus chip and feed it into the 68000?

Either its a stupid question.

It simply doesn't work.

Or, no one has really tried it properly?

I've seen that thread, but there's no one in there who has actually done it.

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.
