I am looking to get a gig stick or two for a Powerbook G4 (15" 1.25ghz configuration.) It appears that the popular demand is for crucial memory, as they are said to offer the greatest performace of all aftermarket memory manufacturers. However, when I visited Crucial's site, I coudn't find a gig stick for my system and their customer support said they don't offer this size of upgrade for my Powerbook. I would like to hear opinions on some of the top performing 1gig RAM upgrades from anyone who can lend some knowledge of their experiences to me. Are there any reliable, compatible third party memory makers for this type of upgrade? I really don't feel like spending $700 for the apple RAM. Help is appreciated.
