Just thought I'd make a quick thread to let people know, that I'm currently running 2x4gb of Corsair vengeance, and 2x4Gb of Kingston HyperX Ram on the Nforce 790i Ultra Sli, with no compatibility issues! Iv overclocked all sticks, running at 1800Mhz, 7-8-7-14-1T, so to anyone who says the board doesn't support 16Gb of Ram, there's your answer!
