I'm looking at upgrading my 2.0ghz MacBook which still has the original 1gb of ram in it. It's served me well but it's time to upgrade the ram finally. According to OWC it's upgradeable to 4gb of Ram but can only use the first 3. First off can anyone verify this? Next has anyone used micron ram? It's available locally at a great price. A 2gb stick is actually about $20 cheaper Then the Kingston valueram that another store has on sale right now. I'm not really familiar with alot of brands of ram as I usually just use what came in the computer and make the best of it. So basically I guess it boils down to is the micron worth $30 for a 2gb stick of pc5300 or is the Kingston valueram 2gb stick for $45 a better deal?? Thanks!
