Well you can't install RAM incorrectly in a motherboard as its designed to prevent it.
The speeds are fine actually. Remember, it displays the frequency at half of what it is (my RAM also operates at 1600 and CPU-Z says 800.3Mhz right now), so they're running at 1600 (798.3 x 2), which match their specs (okay they're at 1596.6, so not quite there).
As for your single channel problem, did you
1) Install the RAM into the proper slots to enable dual-channel (check your mobo manual to see)
2) Flash your BIOS? (updated your BIOS to the current version)
On a different note, your clocks are off. They're currently set at 11-11-11-28, when their specs say they operate 9-9-9-24. Its not a big deal and you can fix it in the BIOS fairly easily. But first things first.
