I'm wondering, can I add RAM from a broken laptop I have? I found my old Samsung RV411 thrown in a closet today, opened it up and saw it has 2gbs of ram. I currently use an ASUS X550CA which has 4GB DDR3 ram running at 800mhz according to CPU-Z. The ram I found is 2GB DDR3 1333mhz. I want to know if I can simply open up my ASUS, pop the stick in there and everything will work. Also, would this give me any performance increase at all? Thanks in advance.
