Upgrading my ram.

[OnlyRussellHD]

I currently have 2x4gb 1600 MHz of DDR3 corsair ram in my first dual channel slots, I was wondering would it work if I got 16gb (2x8) 1600 MHz of DDR3 corsair vengeance ram put them in the first dual channel slots and moved the 2x4gb to the second dual channel slots and even if it does work should I even bother because I heard it loses performance.
Either way I am buying 2x8 gb of ram I am just wondering if I sell/scrap or use the spare ram sticks.

Sorry for the poor wording.

Just use the new 16GB kit as that's all you will need for gaming. No harm done to give it a try however and if they don't work together then you have your choices to sell or keep them as spares.
