I am by no means an expert, but I suspect that if the mobo is rated for 3200 memory speed, you can't run anything faster with a "stock" XMP profile. Perhaps someone with more experience can comment on this.
Now, my mobo is different (ATX instead of your mATX), and my memory is different, but I have been able to boot into Windows with overclocked memory. I've tried it at 3266 and 3333 MHz. Now, I haven't been able to get the timing and settings right to prevent any memory errors, but that is a topic for a different place. The point is, I would think you should be able to at least post with faster memory speeds.
Have you used 1usmus' overclocking guide? He's the one who developed the calculator.

In case you aren't aware, there are things to tweak besides just the timings. Additionally, there is a "V2" profile in case your memory isn't the best (I'm not sure if yours is or not).
Beyond that, I'm not sure I can be of any additional help. Good luck!
