Mar 8, 2014 6:21 PM in response to PowerPC_Fanby K Shaffer,Not sure about the overclocking part; a company who had been in business a
relatively short time and offered a logic board replacement with upgraded 1.9
GHz G4 chip; & was a board-for-board swap, for the most part. Hard to find now.
•Daystar CPU upgrade - iMac G4 flat panel:
http://www.barefeats.com/imup.html
The inaccessible design of these iMac G4 luxo model computers makes for
major difficulties compared to simple open door case tower model G4/G5.
I remember my B&W G3 350 had a way to be overclocked by changing how
the pins on the processor connected. That was another era. Some even had
zif adapters; users worked around the limitations, because there was room.
My iMac G4s don't exactly function, One was able to start but needed the
superdrive replaced, or so it seems. Another may need a power supply,
or it appeared. The Third one was part of a deal where I had to take it to
get the one I wanted that worked OK at the time. Likely it has good parts.
Although this http://xlr8.com/machspeedcontrol-osxandos9combo.aspx may
be a little interesting, that's all remaining from the XLR8yourmac Daystar link.
A CPU upgrade and maybe an SSD such as OWC has for legacy ATA Macs?
Could be there may be some way to upgrade the processor, if you start out
with a pile of repairable iMac G4 1.25GHz 17" or 20" models, and a box of
other items. There is not much room on an iMac G4 logicboard, but maybe
a CPU from a portable Mac may be able to work. Trial & error, & error, etc?
Sounds like a project, of a sort...
Good luck & happy computing!

Mar 8, 2014 7:16 PM in response to K Shafferby PowerPC_Fan,Yes, I know about the Daystar 1.9 ghz G4 upgrade, I've just not been able to find one. And trust me, I've looked six ways to Sunday without finding ANYTHING. It may as well be a ghost at this point. Usually you can find an old CPU upgrade even if it is rare (for the right price). I love my G4 iMac and never want to part with it but would very much like for it to be able to do just a little bit more (processor-wise).
If there is ANYONE out there who knows of a way to successfully overclock this machine OR knows of a Daystar 1.9ghz G4 upgrade PLEASE let me know. If there is Daystar 1.9 out there chances are I'll buy it if it's for sell.
