Hello , today a friend called for helping him upgrade his home pc so i installed him an SSD and 2 x 4 Patriot Mamba 1600mhz ddr3 because i tought that is compatible (according to the asus website). Looks like this motherboard isn't compatible with all ddr3 rams but only some of them so I need some help , which are the requirements and what models that are on amazon italy you suggest? It's not very clear if it's the density 12800 is too much for the mobo to handle but i've been reading that even 10600 can give problems so i desperately need your help.
