What composes the 6GB memory, is it 2x3GB or 1x4GB + 1x2GB?
In the future if I have to upgrade to 8GB, I need to know if the pre-installed or any of the pre-installed memory would be usable.
We can't confirm for this model, since it is refurbished. We recommend inquiring with the retailer directly, and in this case, the Geek Squad can also open the unit up and inspect the memory configuration for you.
Thanks for your interest in Samsung laptops.
