Hi all. I'm wanting to upgradge the ram on my G4 powerbook 1.67GHz and am a bit stuck.

It currently has 512MB in one of the slots and in system profiler it reads :

SODIMM0/J20STANDARD:

Size: 512 MB
Type: DDR2 SDRAM
Speed: PC2-4200S-444
Status: OK

I wish to install another 1GB on top of that. I have gone through all of the steps on Crucial.com for finding the appropriate ram for my computer. on the page ( http://www.crucial.com/uk/store/lis...k G4 1.67GHz (15-inch Display) DDR2&submit=Go ) there are two options for 1GB chips. Would either of them be incompatable with the exisiting chip I have, or would it be advisable to get one over the other?

How they differ is one is DDR2 PC2-4200, the other DDR2 PC2-5300, and one is DDR2-533, while the other is DDR2-667. They are only £10 different in price so I'll get whichever one is faster.

Thanks!
 
I would go with the RAM that is already installed in the computer (the DDR2 PC2-4200). Your PowerBook G4 may recognize the faster types of RAM but will probably only operate it at the DDR2 4200 speed.
 
I bought Ram from crucial and went with the faster piece and when I installed the Ram it showed up in my system profiler as a slower piece of Ram than was originally installed in my powerbook. I sent it back and got the matching piece and I haven't had any problems since. The moral of the story...go with the matching Ram. :)
