    I just got a strange idea. I thought of putting 4GB RAM into my PB. Is this really possible?

    Would be nice if the older PB can handle 4 gig and the MBP not ;)

    Yes, you can put 4GB into the PB.

    But it won't recognize it.

    I tried

    I have a Powerbook G4 1.67 Ghz, this machine use DDR2 533 SODIMM Memory. I just bought from Kingston 2 pieces of Ram Memory with 2 GB each (KVR533D2S4/2G).

    If I install just one SODIMM the Powerbook recognize 2 GB on Ram. But if I install the 2 pieces of Ram Memory the Powerbook doesnt start up. Just receive a strange sound and a white led on and off.

    If I install one 2 GB SODIMM with any other (512 MB or 1 GB) SODIMM I have the same. My Powerbook doesnt start up.

    So I leve just one piece of SODIMM with 2 GB. Is there any way to make my powerbook to recognize 2 pieces of 2 GB ??

    No. It is a hardware limitation of the motherboard. Never has and never will support more than 2 GB. The 1 x 2 GB SODIMM configuration I would not assume would be stable.

    Shoulda checked before buying the 2 GB modules.
