So, i purchased a new Macbook Rev C when it was announced in June. It came with stock 1GB RAM which i find isn't enough since i use XP on Parallels simultaneously. I was considering getting new RAM and after browsing through different threads here, i've noticed most people suggesting OWC. I went to their website and noticed that they had quite a few capacities and brands available. I've read that having matched pair RAM marginally boosts performance. I've also read some contradictory statements regarding the same so i was wondering what exactly i need to do. Look at the configurations below and suggest what you think is the best: 1) 2 x 1GB for $104 (Micron) 2) 2GB single module for $157 (Micron). Adding this would give total 2.5GB. 3) 3GB (2GB + 1GB) for $159 (OWC). This is what i am inclined towards. Also, is there any advantage in purchasing Micron over OWC? I've read that Apple uses Micron RAM which leads me to believe that Micron would be the more logical choice. I've also noticed that Newegg has some great deals on Apple RAM upgrades from Corsair, for eg 2 x 1GB for $80! What should i do fella's?
