Fastest 640e pin compatible to CS-PPC?

Just from what I recall, there might be a 250Mhz version
that is compatible.  I believe the faster 604e that were
used in upper-end powermacs like the 8600 and 9600 use
different voltages and bus speeds.  They also used a different
motherboard vs the models that use the 604e in the 180-233
range.  My gut feeling is these will not work with the cyberstorm.
Again, I am no expert on this.

Even if the early G3s are pin compatible, I don't think
they are actually faster than the 604e.  The G3 was more of
a replacement for the 603 if memory serves.  I do know
that the 604e stayed in service for a few years after the
introduction of the G3 in server and workstation
machines.  I think the 604e has a better FPU than the
early G3s.  I need to research this some more.
