Let's check if it's configuring properly. First, make sure using slots 2 & 4 from the cpu, not 1 & 3.
When go into the bios, in advanced, you need to select/use DOCP profile for 3200 not manually select ram frequency to 3200 which causes poor timings. This will allow it load the memory profile, the same Intel XMP does. If your experience is from Intel system and you selected ram frequency without using XMP the same thing would happen.
Example:-
Also make sure up to date on the bios, ASUS AGESA 1.0.0.4 BIOS was released today for most if not all boards applicable.
If your done all this and test and still have an issue with your ram. post back.
Hope you find this of help.
