the new ibook uses PC2700 ram, here are the lowest prices.
That is so totally wrong it's not funny.

Those links are PC2700 DIMMs for PowerMac G5 towers. They don't fit even if you fold them in half. ;) The iBook takes SODIMMs

Seriously, choose RAM for an Aluminum Powerbook G4 12" 1/5 GHz and you'll be safe on the iBook G4/PC2700 until the rest of the web sites catch up with us and list the new machines :D

The new iBook manual states:

Your computer comes with one memory slot that you access by removing the
computer’s keyboard. Your computer also comes with 512 megabytes (MB) of Double
Data Rate (DDR) Synchronous Dynamic Random-Access Memory (SDRAM) already
installed on the logic board.

The memory slot can accept an SDRAM module that meets the following specifications:
  • Double Data Rate Small Outline Dual Inline Memory Module (DDR SO-DIMM) format
  • 1.25 inch or smaller
  • 1.25 inch or smaller
  • 200-pin
  • PC2100 DDR 266 Type RAM or PC2400 DDR 333 Type RAM

Note: Your computer processes data at the speed of PC2100 DDR 266 Type RAM.
You can install PC2400 DDR 333 Type RAM, but your iBook will run at the lower speed.
Now isn't that confusing when we look at the tech specs?
Memory (DDR SDRAM) 512MB PC2700 (333MHz) DDR SDRAM; supports up to 1.5GB; 1 available expansion slot
So what shall we take as the truth?

Will i really notice much of a difference if i buy 512MB more for a total of 1GB or RAM compared to maxing it out w/ a 1GB stick? I installed 256+512 onto my 1.1 Athlon and find i dont use 1/3 of it most of the time. In other words is the difference in performance worth the extra 50 bucks id spend on buying the Gig strip?
