For some context as to why I'm asking this question, feel free to visit my thread in the Mac and PC Games forum: WoW Performance Issue. I currently have 4 GB of RAM on my Early 2008 iMac. The website where I purchased my RAM (Crucial), said that the 4 GB I currently have is the maximum. However, after doing some searching on the web, some people are saying that my model can handle up to 6 GB of RAM, and some are saying that it has been tested to work. So I come to you, the Mac experts of the internet, to tell me the truth. I feel as though 4 GB is the maximum. It's what I've believed for some time, and it seems to be the general consensus aside from a few people who claim otherwise. But if 6 GB of RAM is a possibly, then it's definitely something I'd like to check out.
