Hello,

I am planning a memory upgrade for my laptop which has this RAM:

And the RAM I'm going to buy is:

Notice the slight difference of the numbers underneath the RAM specifications. Mine has PB NO AC and the one sold near me has PB NO AA. As I am totally clueless to what the numbers mean, is it okay if I install them?

I read that mixing your RAM is basically bad and the best way is to get identical ones. So I need an experts opinion(you guys!) before I splash cash on this guy. Thanks!

My laptop specs if it could be of any use:
