Ok so if I have this motherboard - MSI 790fx-GD70 And this RAM - 4GB DDR3 1600 AMD Edition Would it be recommended to use 1 kit of the RAM for 4gb total? Or is it better to say, use 2 kits of the RAM for 8gb total? Reason being, I purchased 2 kits of the RAM, 2 x 2gb totalling 8gigs total, but now wonder if it's overkill and better off performance wise to just use 2 sticks at 4gigs instead of 4 sticks at 8gigs. Any quick help is greatly appreciated. Keep in mind the above RAM is with a Phenom 965 BE and Toxic 5850 If the majority say 1 kit will do perfectly, then I will need to sell the other unopened kit I think.
