[SOLVED] What RAM would work on my Toshiba laptop ?

[wheresmabluetooth]

I have a Toshiba Satellite L740 with 2 x 2GB of Samsung M471B5773DH0-CH9 [ DDR3 1333MHZ]

I'm wondering what my options there would be for a 2 x 4GB setup of compatible RAM? Ideally I'd like to stick with the same RAM manufacturer (Samsung).

Many memory vendors have product selectors where you cn find comparable memory for your laptop.
This site says you can fit 2x4GB modules.
