Is there any correlation between core type, PCB
type and max. core speed?

So far in this thread we have:

Me R360 ProPCB 403MHz
Inglo ? ? 402MHz
Pudj R350 ProPCB? 411MHz (more?)
ShamB ? ? 430/445MHz

Not necessarily all done through ATitool.

I'm still curious as to whether the ProPCB
undervolts the R360 core leading to it
overclocking poorly. If anyone wants to add to
this list feel free. I think I'll get my meter
and look at the core voltage.

[A curious point: My vidcard supplier (scan)
stuck their own warrantee invalidation sticker
right over the place where you might want to
solder/measure voltages to increase the core
voltage. They're not as green as they're cabbage
looking].
