I just recently installed 12gb of Ballistic Tracer 1600MGz RAM on the my R3E. I am having a little issue with it though. When I installed it The top lights are very dim and are not tracing at all. As far as my Bios are concerned I have version 8.x installed as I was having issues with version 10.x. Unfortunately I am not very versed in Bios tweeting so I am not sure if there is something that I really need to adjust there or if it might be an issues with something else all together.
My system:
R3E
i7-920
ASUS 460 OC version
12gb Ballistic Tracer 1600MGz
