So when i built my pc about a month ago the motherboard i ordered came with a free 8Gb stick of RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820148661), and that motherboard died so i tried to RMA it with Newegg and they wouldn't take it, so unfortunately i'm having to buy a new motherboard. Once again, Newegg is offering free 8Gb sticks of RAM but its a different model (http://www.newegg.com/Product/Product.aspx?Item=N82E16820148540). I want to know if it would be possible to mix the two sticks of RAM, or if there's something you can tweak in BIOS to make them work. Thanks in advance for the help.
