12mhz 68000 at 14.3mhz???
« on: July 20, 2007, 02:09:03 PM »
I can get hold of a 12mhz 68000, and was thinking of doing the 14.32mhz hack with it. I am a bit concerned that this might be too much of an overclock for that chip. Has anyone ever tried this? I don't really want to do all the work if there is not a high probability for sucess...

If I was you I wouldn't bother. Is there a need for it?

It doesn't help because the bus still runs at the lower speed I did this and added a 68881 chip a long time ago with the special libraries. I saw a 2 to 3% increase in speed overall. It wasn't worth it. It was a fun project to get to know the machine though.

it'll probably work... there were some guys overclocking Gennys from 7.67MHz to 13.5MHz and some chips even went 20+MHz

I gather that replacing the 68000 with a 68010 can give a worthwhile speed boost for some processor intensive operations - and you only need to pull the 68000 from its socket and push the 68010 in instead.

Software-wise, run Decigel or some such, and then most things should work fine.
