Hey there. I just purchased a white MB 2.0 Ghz model. I am looking to upgrade the RAM. I didn't from the reseller that I bought it from because they were selling a 1GB stick of Kingston for $200 CAD. That seemed way too much. So, now I am looking for something more cost realistic. I have found this, it is a reliable company as far as many of my friends are concerned. Just wondering if this RAM would work with my MB - http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1818151&Tab=0&NoMapp=0 If you have any other suggestions please let me know. Also, does the MB require matching sticks, or would one 1GB stick and one 256 MB stick be fine? thanks for the help!
