I'm not computer illiterate lol, and I know everything i need to know about the ram. I wanted to get 1 4GB stick and 1 2GB stick for a maximum of 6GB of ram. I have a 2008 iMac, so thats all it can take. I went to OWC but there ram is overpriced, $130 for 2+4gb pack. Can someone recommend me some good ram? dd2 800 mhz Thanks!!
