What is RAM capacity for G4 iBook 933MHz model A1055

I am getting conflicting answers to to my question. One vendor is telling me that they have failures trying to upgrade to 1 GB, that this machine will only read a 512 GB stick.

I rather believe the iFixit guide that says it will take the 1 GB stick, and since there is 128 MB built-in, that should total 1.125 GB, right?

Answered! View the answer I have this problem too

Is this a good question?

Apple reports that the maximum memory capacity of this system is 640 MB with 128 MB onboard and a 512 MB SO-DIMM. However, third-parties have been able to upgrade the system to 1152 MB with the 128 MB onboard and a single 1.0 GB memory module. http://www.everymac.com/systems/apple/ib...
