all the pci powermacs have a jumper block that controls the multiplier of the cpu
easily accessible just by removing a warning sticker
for those of us who have one of these machines but cant find the powerlogix 1ghz ZIF that user "Dane D" has :'(

but, is there any danger to trying this? can it damage the cpu?
i guess id be silly not to try it.. if there is no danger involved..
to go from 450mhz up to 500mhz... easily attainable? stable?

seems to be only one jumper to move to go from 450mhz to 500mhz!!!

zif cpu upgrades

i guess all of these would work in my b&W? but i cant find any of them for sale :'(

i just checked my jumper block
it has 11 jumpers
not 4
????
this must be only for the first revision b&W's
ok wait.. i see now

they discuss only changing these 4 jumpers of the 11

SUCCESS!
my g3 450mhz is now reading 500mhz!!!! ;)
i wonder if it will be stable...

Congratulations!

If you are bitten by the overclocking bug, you'll be infected forever... LOL
-
LOL!
it appears to be working just the same... no loss of stability :D
easiest overclock in the history of all mac + pcs!
I really do think that classilla is running significantly faster...
before when i tried to load macintoshgarden it was brutally slow
now its not bad
maybe im imagining.. can 50MHz make a huge difference?
-
heres my result 8)
i stopped the test after floating point
almost close to synthos result of his g3-500

I could reach 500mhz with a 450mhz G3. I had to use additional cooling for gaming (Shadow Warrior would lock-up in E1L4), but it was rock stable proper cooled.

i think its fine with the case closed and the 120 fan blowin. but i was thinking i might add a fan directly to the cpu
it is totally running hotter then before. but i think its ok.. its not freezing from the cpu.. it seems pretty stable .. it hasnt given me any problems when im not trying to install 8.6 / 8.5.1 :D

heres a geekbench2 result of 1.1ghz powerpc g3
http://browser.primatelabs.com/geekbench2/627052
showing it to be almost identical in performance to the Quicksilver Single cpu 933mhz
that means u could run leopard with this lil chip on a b&W i bet! not that id want to :)
but definately alot more lifting power for vst plugins + ableton live under mac os 9!!!

here are some pics to help you identify if your g4 is a yikes model
-
If only I could reach stable 500mhz with the original G4 ZIF... :(
-
get a g3 450mhz cpu and clock that to 500mhz
it works
-
I have already done that. I wish I could do that with the G4 because of its benefits over the G3 (Altivec and faster FPU).

Yes it can be done in a G4 also. But a few tiny resistors must be changed instead a few motherboard jumpers...

I also did that, but it wasn't stable. I tried with 2.7V, 2.6V, 2.5V and 2.4V but none were stable.
Edit: Are you talking about the Sawtooth and newer or the Yikes?

I'm talking about Sawtooth and newer.
I'm sorry, I always forget about Yikes ...
