That is true. But in this thread, the CPU in question is a 500 MHZ
OWC G4. Looking at the OWC Site it doesn't seem these were shipped
with special heat sink, the installation instructions say to use you
old one, (in both the beige, the BW (which have a smaller heat-sink)
than the system here
The Short Answer: Yes a bad cpu can give you a good Power On Self

eventually gives you video and boots. You may even have to go to the
lowest setting your motherboard allows before it does gives video and

Well I sprung for a mac keyboard. It is an ugly apple pro keyboard v
1.22 that feels like someone soaked i in bleach to get it clean.
After pulling keys and putting them in the right locations I hooked it
up and was able to boot the yikes board into open firmware with the
original G4 400 MHZ
See, this is the thing, a processor will run UNDER-CLOCKED better than
it will OVER-CLOCKED. If I have a bootable system with a g4-450 mhz.
Putting a 500 mhz processor in there without changing the jumper
settings will only tell the 500 mhz processor to run at 450. Much
like it tells the 400
System: G4 Yikes with 400mhz Processor clocked to 450 / 750 mb
memory. a PC keyboard hooked to the USB port. PC mouse hooked to the
USB port.
I got this processor from ebay. Says it is a 500 mhz G4. DId a one
for one swap with the G4 on my Yikes board. (left jumpers at 450).
Chime, But no
From my own experience a Pram zap may be what you need however If you
can swap in the Known working cpu and zap the ram that way then that
may help you to find out whether or not you have a bad cpu and not a
pc keyboard issue.

If you haven't changed the jumpers, it's likely that could be the
