PPC 604E processors

Apple used these processors for their Macintoshes. Would say a 300 MHz processor work in place of a 233 Mhz one for the Amiga Accelerators? Has anyone tried this?

The crystal? Can you elaborate?

I would imagine it would work. Back in the day, Pentiums (if I have my info right) were basically batch tested at certain speeds/temps. The faster speed/temp then the higher rating the processor got. I'm not sure if this applies to PPC processors and from reading around there does seem to be slight differences between versions.

So it might work...

Well my main point of asking was if I couldn't find a PPC 233 processor then could a find a faster Mac and scavange its CPU for an Amiga project. I would only run it at 233 Mhz.

Also - The PowerPC 604e draws 18W at 233 MHz. The PowerPC 604ev, 604r or "Mach 5" (the faster one) draws 6W at 250 MHz.

1/3 of the power...probably a lot less heat...might be able to go fanless. What's that fan thingie mounted on in the photo link you posted?
