So today I installed Windows 8 64bit, FX-8350,AMD 7970,Sabertooth 990fx r 2.0). Afterwards when I went under my system it showed 4gb's of ram. I have this ram. http://www.newegg.com/Product/Product.aspx?Item=N82E16820233144 Im not sure how much more info I can provide. But I dont have a igpu that could be eating the ram. What should I look for in my bios settings? Thanks
