I am using a Samsung R730 laptop -

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.

If this website is to be trusted: Then the max memory on your laptop is 4 Gig. And I think you can only use 2 Gig sticks.. – Ashtray Sep 4 '13 at 5:25
Yep, you can use 2 x 2GB sticks operating @1066MHz – Ashtray Sep 4 '13 at 5:29
@Alex OK, thanks. If you add that as an answer I'll set it as answered for you – rhughes Sep 4 '13 at 5:47
