what was the 1.6Ghz CPU tested in? if it was tested in a Sawtooth or Gigabit ethernet G4 then it has probably been set to a x16 multiplier for the 100Mhz bus. so for a DA or QS you would have to change that , (16x133 is 2.1Ghz LOL) for a 133Mhz bus you want the 12x multiplier BTW you can also...

thanks for the Shots :) looks like your CPU was made week 41 1999 I also see you have what looks like a Radeon 9200 Mac edition fitted :) indeed you can over clock the BW G3

just reading the system Profiler Rev 2.6 G4... do you mind taking the heatsink off and grabbing a picture of the CPU for me please? in regards to the system profiler shot as bunn says its completely normal just a fun little "typo" apple left :)

Yeah thats what i was thinking :) it would be case of finding 1MB Cache chips then im not sure if there rare or really common not looked into it actually LOL I know max linked to some cache chips earlier in the thread but i think those where 512KB cache chips? (all 750/7400/7410 Macs I have...

cool sounds like a plan :) next big thing to try on a clamshell would be upgrading the L2 cache, trust me L2 cache makes a world of difference on these old Macs :) 512KB is much better then none but 1MB would be even better :) (the chip does support 2MB of L2 cache but im not sure if that...

Very nice :) good to see you have the thermals under control enough to do a GB run, 255 thats a nice fast iBook clamshell :) Btw  I noticed your using GB2.2.0 thats the latest version for tiger but for leopard 2.2.7 is the latest :)

Very nice! Thanks :) they are appreciated. good to see you got leopard optimised i have a Leo OS9 combined image i made and i disabled spot light for that reason as indexing will just eat the CPU. indeed an SSD should perk it up a bit I had my Pismo fitted with a 16GB fast CF card for a little...

wow! even though i had a strong feeling it would work its still so amazing! :) the first iBook clamshell running a production version of leopard :D does everything on the iBook work in leopard like Sound sleep brightness control etc? id think it should... btw got any system profile shots in...

Ill think about it (I just spent a lot of dosh recently so not sure if i can budget one) but good to know there is one available and that shipping aint as bad as i was expecting :)

it might be worth it to fit a DVD drive to that clamshell also Good to see its now Fully detecting the G4 :) BTW do you have any more clamshells for sale and what shipping to the UK is like? just wondering :) (I would not mind making a G4 clamshell my self)

Very awesome! :) told ya the firmware update would solve the issues :p Does System profiler/Open Firmware properly identify the CPU now as a PowerPC G4? (it should) Just need to solve the Thermal issues now and run leopard :) (and maybe figure out how to upgrade the L2 cache to 1MB hell...

trust me I have had a lot of experience running OS X (leopard inc) on vastly incompatible/unsupported hardware :) check out some of my posts over on Mac Rumours for some details :) (10.4.11 on a 604 anyone? :) )

I dont know what sort of issues your having with leopard (if you could describe them it would help a lot) but i have seen firmware updates help with leopard (specify a G4 cube). in regards to OS9 you may be able to boot (albit slowly) from a USB stick of some kind or if your HDD has OS9 drivers...

exactly what i was looking for thanks :) very interesting indeed it does not properly identifier the CPU but still picks up on the L2 cache heh (the CPU Type field is pulled directly from OF if you go into OF and temp edit it to say "PowerPC is Awesome" it will show up as that in OS X heh) I...

very coo thanks heh :) I did warn you about the thermals is there any way to adapt a bigger heatsink perhaps out of copper? also what sort of issues have you been having with Leopard and where/what part does geekbench/the system freeze on? also I do appreciate the shots :) but I did...

Gave it another reflow. the L2 cache still not showing up/is reporting cache failure in POST messages. I dont want to keep reflowing the board as it is getting kinda crispy so to speak so ill just leave as is a 600Mhz G4 Pismo with no L2 cache LOL tho maybe if i can learn how to reball i might...

@belgaonkar I do recommend updating to 10.4.11 once your done with said app as the update contains many bug fixes and improvements :) btw got any pictures of it running OS X? system profiler shots etc? I have been asking for a good while now :) @TarableCode theres still a few for sale but...

LOL! :) the FireWire clamshells (I assume thats what your referring to) use the 750CXe CPUs and are not compatible with any sort of G4 upgrade the only iBook G3 that is compatible is the first non FW Clamshell iBooks (PowerBook2,1)

another status update still mucking around with the Pismo :) I got the thing clocked up to 600Mhz! its quite fast at that speed especially with the 1MB L2, I did get it benchmarked in tiger. tho while doing so in Leopard the L2 cache died again mid benchmark and crashed OS X LOL and when i...

AFAIK cache is tied to the CPU speed (CPU speed goes up so does cache). how far the cache can go im not sure on one hand most of the reports I have seen say L2 cache G3/G4s dont over clock that well on the other hand we do have the G4 Upgraded iBooks rocking G4s at 533Mhz with L2 cache near...
