Hello! I currently have 6GB of [Corsair Dominator (3x2GB) DDR3 1600MHz XMS3 Memory (8-8-8-24)(TR3X6G1600C8D)] memory installed on my system. Looking to buy another 6GB. My current memory version is 3.1, the version I've seen to buy is 3.2a. Will this be an issue when running them together (12GB in total)? Thanks!
