I want to purchase RAM for the last G4 iBook model, but its listed as using PC2700 333mhz RAM. I found a good deal on powerbook RAM, but it's PC2100 266mhz. What's the difference? Should I get it for my iBook? Any compatibility issues?
PC-2100, if installed in that machine, will run at PC-2700 speeds. (Read: Overclocked RAM). That may or may not cause stability issues, and possibly hardware failure. It is not recommended. Get the proper RAM for your machine.
If it is the 1.42 GHz model, it likely won't boot with the PC2100 module -- the Mac checks the SPD of the module. Haven't tried it myself, don't recommend that you do either.
