Hello guys, my uncle gave me a MacBook 2007 (mid 2007 2,1). I am planning to use it for school, but there is a really small RAM (2GB), browsing in chrome uses 90% RAM. I need one more 2GB RAM. I need to know what RAM can I use. At this moment there is a 1x 2GB KVR800D2S6/2G.
There is a one empty slot for RAM, so basically all I need to know is if I have to buy the same card that already is in this Mac or if it can be a different one. If the second possibility is right can you give me some examples of these RAMS? Thanks a lot!
