I'm using this macbook for the past 2 years. From the 1st day of my usage, when ever I open multiple applications (like Fireworks, Dreamweaver, Safari, Preview, iTunes etc..), my macbook making so much noise (I guess it is fan rotating noise only). Does it mean, my 1GB RAM is not good enough to run many applications simultaneously? Should I upgrade it to 2 GB / 4 GB RAM??? If so, can I go for Transcend RAM? My vendor says he already installed Transcend (2 x 2GB = 4GB) RAM to many Macs and they are running fine. They costs me around INR 4500 (~ USD 100). When I ask about the Apple RAM (http://store.apple.com/us/memorymodel/ME_13_2_2_MB_G4), he says it would costs me around INR 17000 (~ USD 400) to get them for me to India Now I would like to know whether this problem is because of my poor 1 GB RAM or not. If so is it advisable to upgrade with Transcend ones?? Thanks in advance.
