I successfuly exchange 1 GHz CPU on my second Pegasos 2 to this one:
MC7447B 1667 MHz ( from ebay / 10,- USD )

Just now it is overclocked to 1800 MHz and I start testing...
Peg2-1800MHz.jpg

And I have question:

if CPU clocked to default 1667 MHz, SmartFirmware shows cpu0: PowerPC,7447A CPUClock 3428 Mhz
if CPU clocked to 1800 MHz, SmartFirmware shows cpu0: PowerPC,7447A CPUClock 1799 Mhz
Why Smart firmware ( and OS too ) shows double value for 1667 and are there way howto fix it?

P.S. in meantime when I waiting for Mirari, I has to upgrade a little bit my pets.

I would just be silent about the wrong display and show everybody "look, I have the fastest G4 in the world in a 3.4GHz Peg II!"

I have no idea how SmartFirmware calculates, though.

Congrats on that catch, let us know if it runs stable in the long run. I wonder if it's worth the risk. Mine is still at 1.0GHz. It would hurt if I broke not just a 10 EUR CPU but maybe also the CPU module or even the mainboard.
