Looking to finally add some memory to my 15" powerbook G4 1.67 to hopefully squeeze another year of life into my powerbook before I fork out for a MBP.

Everywhere I look, including apple, the specs given for my machine is PC2700. When I look at the current module in my powerbook it is reading as follows:

Speed: PC2-4200S-444

Can someone tell me if this is correct and I should be get the 4200 and not the 2700? I bought this powerbook years ago used, so I don't know if someone replaced the memory incorrectly?

I'm looking to max out with 2 2gb sticks so i will be taking out the old module.

thanks for any info.

As far as I know, the max memory is 2GB. 2x2 will definitely not work.

Gotcha. I would just get the memory type that apple specifies, I'm surprised the other kind actually worked.

The 1.67ghz Powerbook came in two different revisions.

The last revision had a high resolution screen and was the final Powerbook G4 ever made. It took PC2 4200 Ram.

The revision prior to that, had a lower res screen and took PC2700 ram.

If your machine has the first type of ram, get that. I am not sure you can upgrade to four gigs, but that would be an interesting experiment.

as yours has PC2-4200 then it's final rev of the 12"powerbook 1.67

your max amount of ram is 2.0 gig

thanks all, I will get the 4200 then. It just really threw me off when apples spec sheet doesn't say anything about that. At least, I didn't see it. I know someone will post a screen shot of the info on some support page somewhere.

thanks all.

Your chipset will only read 2gb max. You can install 1x 2gb PC2-4200 or 2x 1gb PC2-4200 sodimm modules into your G4 Powerbook. Whatever you can find the cheapest I'd get.

Now throw in a larger/faster HDD and you'll be all set, if you haven't done so already.
