I'm going to pick up a new PB, and I know that Apple's RAM prices are outrageous. When I got my iMac, I got an upgrade from RAMJET. It's worked great with no problems. I'm looking for DDR2 modules for the new PBs, and I have a question. Do I need to get a memory module specifically labeled for the PB, or can I use any DDR2-533 PC2-4200 module. RAMJET doesn't show any DDR2 modules, and Crucial has this one for about $135. Someone on another thread posted a link to this Kingston module from ZipZoomFly, for under $100. That would save $70 on two modules. Will the Kingston module work? I've seen RAM in CompUSA that was specifically "flashed" or configured for iMac or PowerMac voltages. Is this a load of crap, or is it needed? Thanks.
