The iBook has 128Mb of RAM soldered onto the logic board. It is non-removable and non upgradable In addition the iBook has a single SO-DIMM slot which can accept any low profile 3.3v PC100 (or PC133) S0-DIMM of up to 512Mb in capacity. Giving a maximum total RAM of 640Mb. So yes a single SO-DIMM will work in addition to the 128Mb base RAM.
The 128Mb built in memory (PC100) will work fine with your new PC133 Memory. The PC133 will just downclock to the speed of the PC100 automatically.Originally posted by Hemingray
PC133 RAM will work just fine. Same thing happened when I ordered RAM for the old beige G3 (PC66) at the office, they sent me PC100 RAM. I'd say it's because it's cheaper and more common, and since it's "backwards compatible" it's perfectly alright to use.
