I've been having trouble with the "Advanced Memory Settings" in the UEFI DualBIOS on my GA mobo. I have two Corsair Vengeance 4gb ddr3 1600 MHz sticks, and the automatic setting in the bios is 1333. I can change the xmp from disabled to profile 1. If I do this, the system memory multiplier changes from 13.33 to 16.00. However the MHz is a dark blue color and still reads 1333, even though on the right it displays 1600mhz in a greyed out text. Also greyed out and dark blue is the profile DDR voltage. I don't really understand what a lot of this means, and some understanding would be appreciated.
