    Well, i own an iBook G4 800Mhz. I'm thinking about adding some RAM into it as it's currently extremely slow. Probally because Azureus is running almost 24/7. But anyway, I'm not sure about how much RAM i can put in there and what type of RAM. I'm certainly not going to buy RAM from the Apple Store as it's a stupid move. According to my iBook Box, it "comes with 256MB of DDR SDRAM; Supports up to 640MB". So my question here is how much RAM i can put in there? How much RAM must i buy if i want to,
    1) make my iBook's total RAM to be 512MB
    2) make my iBook's total RAM to be 1GB
    How many RAM slots are there in the iBook? Well, i dunno, i heard that one 128MB is soldered or whatsoever but i'm not sure about this. Anyone with the same model around knows anything about it? I'm really uncertain about RAMs and please give me the full name and details on which RAM to get. Thanks in advance.

    It has 128 MB built in, and there is one user-accessible slot containing:

    128 MB for a total of 256 MB
    256 MB for a total of 384 MB
    512 MB for a total of 640 MB

    You'd replace your existing 128 MB module with a 512 MB module to get to 640 MB.

    Aim for something along these lines: 1.25-inch PC2100 (also called DDR266) DDR SDRAM SO-DIMMs.

    Oh, and although Apple doesn't admit it, you can put in a 1GB chip for a total of about 1.128GB. These chips came out after the iBook G4 which is why they're not mentioned in any of Apple's official technical sheets. :)

    It means at the moment, my 256MB of RAM, one 128MB is from the built-in and another 128MB from the user-accessible slot?

    So if i get a 512MB RAM to slot into the slot, i need to remove the 128MB and get a total of 512+128MB RAM in total (640MB) okay cool...thanks

    Exactly right. My iBook has the inbuilt 128MB chip coupled with a 512MB one for a total of 640MB. :)

    In terms of making sure that you buy the right memory chip, I tend to use Crucial since their site provides a handy wizard to ensure that you buy the right chips for your model of computer. I bought 512MB PC133 for my PowerBook from them a couple of years ago and I haven't had a problem. Not sure if they are the cheapest/best place to buy memory from but the wizard sure is handy.

    I'm thinking about Crucial memory at the moment as well. Heard that it's compatitable with Macs for sure.

    Apple has been using standard PC ram in all of their machines since the late 1990s. So, any regular stick of PC2100 (2700 is also compatible) SO-DIMM will work just fine in your iBook.

    Apple has been using standard RAM that adheres strictly to the JEDEC standards, including Serial Presence Detect settings.

    However, many RAM manufacturers don't bother to build their RAM to 100% compliance with the standard, because most PC's don't need it. Therefore, some 'standard' RAM does not work. Some models of Mac are more tolerant of out-of-spec RAM, but some, such as the 15" and 17" AlBooks 1.33 GHz and under, will crash and burn with, for example, a 'standard' Crucial CT12864X335.
