Hey, quick question for all you who're more technologically with-it than I am. I've heard repeatedly how important it is to max out RAM on your Mac, so I'm planning to upgrade my PowerBook's 512MB to a full 1GB. The problem is that the 512MB comes as 2 256MB DIMMS, whicih means that I'll probably have to sell those on eBay and get two 512MB DIMMS. I found 512MB DIMMS by crucial for $139.00 a pop, which is really really expensive, seeing as I'm a student. However, I also found the same DIMMS on eBay for ~40 bucks, and although the seller had really great feedback, he neglected to name what the brand of the DIMM was (leading me to believe it's some no-name generic brand.) Would it be okay for me to save some money and go with the eBay seller's brand, or will I need to bite the bullet and go for a namebrand like Crucial? Thanks a lot for your help!
