Hi, I would like to expand my iBook memory. Now it has 256MB (i guess
it's built-in, and it has an SO-DIMM slot (what is an SO-DIMM). But I
really don´t know if I can buy any SDRAM DDR (What DDR means?).

Also, I would like to know if there is no problem getting a 256 or 512
MB dimm.

Thanks for your help!

I think that Arstechnica has a good overview of what the various
acronyms mean. Others exist also, but you should definitely look these
terms up.
Here's more than you ever wanted to know about RAM:
http://arstechnica.com/paedia/r/ram_guide/ram_guide.part1-1.html

Briefly, an SO-DIMM is a designation for the physical size of the
memory: Small Outline-Dual Inline Memory module. DDR stands for Double
Data Rate.

For fun, you might just search the group archives on this subject (and
related keywords). You'll find lots of good information.

I just bought a 512MB SO-DIMM for my new PB from OWC. It was on sale
last week there. Places like RAM-seeker can tell you where prices are
good.

Also <http://www.oempcworld.com>, got 512 MB iBook G3 RAM there
really cheap, plus a 30 day money back guarantee and a trade-in
option for my old RAM.

Buy the recommended RAM for your system. Do not buy something thinking
it will do the job. There is the form factor, there are the correct
number of pins, there is the access protocol, there is the access speed.
Getting the wrong memory for your system will either just not work, or
it will cause your system to crash.

There are several on-line memory services. I happen to start at
http://dealram.com but there are others that will allow you to enter
your computer and list vendors by price that have memory for your system.

If you get and install the memory _AND_ you find your system is crashing
a lot, then suspect bad memory, and remove the new memory, see if the
crashing continues. If it does not, then get an exchange for the new
memory.
