Hi all, thanks to the good users of this forum I have recently gotten my G4 1 GHz Powerbook back up and running. I would like to upgrade it to Leopard but I want to make sure it is not unwise to do so. According to apple.com it already meets (barely) the minimum requirements, but I want to beef up the RAM anyway. So I have two questions:

1. Has anyone here upgraded their G4 pBook to Leopard?
2. What is the max RAM I can install in it?

Thanks!
 
A PBG4 1Ghz should run Leopard fine (since even PBG4 400s will run it), just without many of the graphic changes, and you may want to make Time Machine a manual process. As for RAM, I believe the maximum of that level of PBG4 (both Ti and Alu) is 1GB.

Depends whether it's an aluminium or titainium powerbook and how big the screen is if it's an al-book.

If it's a tibook it's 1GB if it's a 15/17" albook it's 2GB and if it's a 12" albook it's 1.25GB

Get at least 1GB.
 
Which 1GHz PowerBook G4 is this, specifically? 12"? 15" Titanium? 15" Aluminum? 17"? This will affect the answer.
 
It is a 12" Aluminum 1 GHz PB. According to the specs, it currently has 512 RAM, 256 of which is built in. Which means it must have a 256 MB stick on the slot. If there is a 1 GB max on the RAM, and 256 built in, then buying a i GB stick would not work, correct?
 
No, that model 12" PowerBook supports up to 1.25GB of RAM. You can buy a 1GB stick and put it in the user-accessible slot and be maxed out. Just make sure you get a stick of DDR PC2100 (DDR266) SODIMM, as that's the type of RAM that's compatible with that logic board.
 
I have a 1.33 ghz model pb G4 and I have 1 gig of ram. I wish I had bought 2.

Runs leopard great but I'm definitely not one to be patient with his computer. But I still love it and it works well for my needs.
 
Right on folks. I bought a gig stick and am sitting prettily at 1.25 gigs now. Also I picked up the Leopard fampack and am installing now. Thanks for all the input.
 
I have a PB 1.33 ghz 17" with 1 gb ram should I upgrade it to 1.5 gb before I install the Leopard? or should I make it to 2 gb, also where I can get cheap ram, the lower price I can get is $71 for 1 gb.
 
Leopard runs fine on my 12" 867 MHz PB with 640 MB RAM

I installed Leopard on my 12" 867 MHz PB with 640 MB RAM last November and it has run it well since. Coverflow loads slow, and spotlight takes a couple seconds to load a query, but otherwise everything works well. I performed a clean install and ran into 2 snags. One, during the installation the Epson printer drivers locked up the installation process, so I had to start over. Two, after it was installed all songs in iTunes made popping noises for, oh, something like 5 hours, then suddenly stopped. After that hair pulling issue all was well.
