Does anyone know what the best Crucial RAM is for a 2009 MacBook Pro 13" 2.26, 1066 MHz DDR3? The Crucial website suggested this: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=0D805CB0A5CA7304 However, I found the following two options on Amazon (and I would like to stick with one of these because they have local next day delivery available): http://www.amazon.com/Crucial-204-p...264BC1339/dp/B003DZJQQI/ref=cm_srch_res_rtr_1 http://www.amazon.com/gp/product/B001MX5YWI/ref=ox_sc_act_title_1?ie=UTF8&m=ATVPDKIKX0DER Fair warning- I am totally uninformed on this topic, so the answer is probably obvious, but the second Amazon link mentions DDR3-1066 under "specs", does that mean the other will not work? Which one would run the proper way and quickest? Thanks in advance EDIT: Found out which one was 1066 and so I'm going with that (the second Amazon link) rather than the 1333 - at least I know it's fully supported as that's what's in there now. It was more of a confusion about numbers for me. Hopefully this can help someone else.
