Hello there, I am using Crucial Ballistix Sport XT 8GB DDR3 1600 MT/s and my mobo only has two RAM slots, I'd like to add another 8GB Stick but i might have some difficulty finding a duplicate stick in the local market in my country, So i am wondering, Would a different brand with the same specifications work? And if so, Can someone point me to models that would work with the stated model? Thank you for your time.
