I have to play with the frequencies and voltage ... 100MHz is a bit unstable.
Sometimes the systems hangs, no matter what type of memory is used.
It happens in chipmem, zorram, fastmem, 32bitmem.
Tested with analyser, after some passes it hangs.
(I think i have to try different corevoltages or the cpu has reached the limit)
For now i have a rockstable 90mhz setup:

What kind of 68060 CPU are you using? With a rev. 6 CPU (E41J mask set) I am able to use it at 100 MHz without higher voltage, but as you write the system will randomly freeze, it can be after minutes or hours of use.


Rev6 latest mask

MMUTools from Aminet is also a very good replacement.
