I envision two possibilities
1) it may not run quad channel without the same capacity installed in every channel
2) you've installed the dimms into the wrong slots for quad channel

No quad channel for you. You lose!

Joking. Sorry mate. You can't have everything. Congrats on your purchase. Hope you are happy.

The motherboard manual has a nice little diagram showing you how to install the memory for best results. If you have all 4 sticks together, you're doing it wrong.

You may get quad channel if you fill all 8 slots. Not guaranteed, though. Asus is vague on this thing.
