Ram compatibility for macbook pro mid 2012
I found a 8gb stick of ram (pictured below) on an old computer. I want to use it as an ram upgrade for my MacBook Pro (13-inch, Mid 2012) 2.5 GHz Intel Core i5. Is it compatible? My Macbook Pro currently has a 2*4 ram configuration. Can I swap a 2 gb stick with this 8 gb stick and have an 2+8 config, or should I just go with 1 8gb stick?
MacBook Pro, OS X Yosemite (10.10.3)
