Hi guys my motherboard is ms 7592 and on the internet i saw that it supports 800/1066/1333mhz now i got 4gb of ram ddr3 but it is 1600mhz so i tried to put it in but when i turned on my pc it said no video input.Later I pulled out my old ram and on it is written 1600 but it doesnt says mhz.Please does anyone know how i can at least get my new ram to work??
