I am using a Samsung R730 laptop - http://www.samsung.com/uk/consumer/pc-peripherals/notebook-computers/essential/NP-RV711-A01UK-spec
It takes DDR3 RAM. I can't find any specific information on the motherboard, but in general, do you think it would be able to take a single 8 GB stick of DDR3 RAM? One 8GB stick is cheaper than two 4GB sticks.
I am running Windows 8 x64.
