SJR Posted July 28, 2014 Share Posted July 28, 2014 Hello. I would like to add RAM memory to my Acer Aspire 7741Z 4643 laptop. I have DDR3 1066 with 4 slots. Two slots are now used, with 1 G in first, 2 GB in second slot. How can I get 8 GB total? Can I use what I have, and add? Or do I have to get all new?
