Hi all, I'm looking at upgrading the 256mb in my X30, and I'm curious how well most ram works with thinkpads. I know laptops are often picky-choosy, and I'm wondering " If I buy a generic 512mb PC133 stick of eBay, will it work with my Thinkpad? I'm looking more for recognize-compatibility here, rather than will-it-fit-in-the-slot. Thanks! Nate
