How do you overclock a Peg2?
on G4 CPU card you have to remove SMD resistor and sold here dip-switch. And then test maximal frequency without errors. Good cooler is a must.
I made it thanks to
Prober and
tlosmx. Deatiled manual is here:
Probers.czand here are links to my articles:
Amiga Klub Forever + Czech PowerPC User GroupHyperion - Pegasos IIin case of interest I can try translate some parts to English. (Pidgin English, of course)
I did it according Probers manual, but later I changed cooler to
ARCTIC Alpine M1-Passive Socket AM1 - because
Thermalright HR-05 SLI blocked way to IDE connectors.
I made modifications on Arctic cooler (to fit in place) and supply with fan.
Interesting. Do you think you could remove the MPC7447 CPU from a Peg2 G4 board and refit it with an MPC7447A?
That would guarantee 1.4 GHz operation (or higher).
I believe they are pin and voltage compatible.
