Jul 18, 2012 12:33 AM in response to Dougal222by Knucklesmac,Hello,
Sounds like your iBook has a built-in 64 meg of memory. You can increase that to 320 meg by adding 256 meg of SDRAM PC133 14 pin module. Maxing the memory will speed things up a little, but just don't expect a massive amount of speed from it's 366 Mhz PowerPC processor.
I've tried and tested a 512 Meg card in my iBook Clamshell running Tiger, however it was the SE 466 Mhz model.
I don't know it would work in yours. If it does it would max the memory to 576 meg.
Hope this helps

Apple officially reports that the maximum memory capacity of this system is 320 MB with 64 MB of onboard memory. However, third-parties have been able to upgrade the RAM to 576 MB with a single 512 MB memory module.
I would go for the 512 MB memory module.

Jul 18, 2012 10:35 AM in response to Ronda Wilsonby Dougal222,Thats great news. I know it wont be super fast but jumping from 192MB to 576MB should make quite a big difference especially since i'm running Tiger which makes good use of the ram.
What spec of RAM should i look for ? PC133 SoDimm ?

Jul 18, 2012 10:46 AM in response to Ronda Wilsonby Knucklesmac,I've heard of some firmware hacks on the early clamshell (300Mhz) to get 512 Meg working, however when applying 512 to my clamshell, it worked without fault. Not to say that it's going to be the same for every model, so I was very cautious to suggest.

Jul 18, 2012 10:48 AM in response to Dougal222by Knucklesmac,You would need 512 PC133 SDRAM. Not easy to come by and can be a bit expensive as they were the last PC133 RAM modules for laptops to be made.

According to Apple, keep it at PC100:

Jul 18, 2012 12:59 PM in response to Knucklesmacby Ronda Wilson,Firmware hack not necessary, as far as I know (as long as you don't try to use PC133 RAM).

Jul 18, 2012 3:18 PM in response to Ronda Wilsonby Knucklesmac,I knew there was some firmware hack, never looked into it in that much detail to be honest. I was not aware that PC133 would make a lot off different considering it's only the data rate maximized by 33hz. Which I believe the clamshells couldn't handle that well under OS 9, but are fine when the 2001 firmware update was applied for Mac OS X. Which probably explains why mine is happy to run 512 PC133 under OS X 10.4.11.

Jul 18, 2012 3:23 PM in response to Knucklesmacby Ronda Wilson,You are supposed to update the firmware before installing OS X on the clamshell models. Not doing so can really foul things up.

Jul 18, 2012 3:33 PM in response to Ronda Wilsonby Knucklesmac,Totally agree. Don't get me wrong, my clamshell has always followed any updates as and when they were released. Baring in mind I've owned it all it's life :)
