If you decide to play it safe, then why not settle for 60MHz on both CPU and FPU?  That's a 20% speed increase which is substantial.  But make sure you keep the CPU and FPU cool, and any other IC's which generate heat.

I agree completely and understand the risks. 66mhz was as high as I was willing to go, will probably settle at 55 or maybe even 60

I understand the desire to squeeze more out of your machine but I would advise against, to be honest. Back in the day, I overclocked my old 68040 from 25 to 30MHz (equivalent to your proposed 50 -> 60 MHz). It didn't make a huge difference in terms of performance to be fair and was less stable.

Now I look at it from the point of view of longevity. I'd much rather have a stable system than a slightly faster one.

If I want raw speed for 68K apps, I use UAE. It's pretty much impossible to beat.

The 68040 is another animal altogether, much hotter CPU. But I agree might just do 55mhz just for the heck of it
