Hello there, I wanted to add 2 more gigs of ram to my system. right now I have 4 GB of DDR3 1600Mhz dual channel ( 2GBx2.) What I want to know is if I put in another 2 GB stick of 1600mhz DDR3 ram that is not the same brand, voltage, or cas, will it still work in my machine? By the way my motherboard is an msi 770 G45.
