Hello- I finally added 1 Gig of RAM to my powerbook g4, which used to only have 256. I bought a gig of ADATA and a gig of Crucial, and tried the cheaper one first... so, ADATA is compatibile.... but some weird things are happening: 1. my iTunes has already shut down a few times randomly? 2. my iPhoto is only slightly faster... with a full extra gig, i was expecting to ZOOM through things! 3. at one point i randomly got a screen with a translucent gray box in the middle, telling me in different languages to restart... So my question is: 1. Is this normal for new RAM? 2. If I installed the Crucial RAM instead, would it perform any better? or Ram is Ram and if it works the first time it works? Thanks, y'all!
