Having spent several hours to no avail, here goes: I had two 4gb Adata ddr3's that died and sent off under warranty. While waiting I replaced them with two 4gb Corsair CMZ8GX3m2A1600C9, which are running fine at 1600 C9 in dual channel mode in the same color slots on my Gigabyte 970A-UD3P board. So now months down the road, Adata sends me back two 4gb AX3U1600C4G9-DR sticks of DDR3. AMD says that if I populate all 4 slots with dual rank ram, then my FX-6100 running at 3.8ghz stable will only run my ram at 1333. Not good.

So what to do? Should I stick these Adata into the empty slots? Will the ram really run slower? Or are these single rank ram sticks, and will run fine at 1600? Or is the AMD article out of date?
FYI - My system is part of a recording studio DAW, and is inside a quiet case, which means it is not an easy task getting into the computer case, cuz its inside another case with a bunch of wires coming out of it. I'd rather avoid experimenting if at all possible, both because I am lazy and because I don't want to break anything expensive.
