I get nothing but problems from ANY asus software; I'm proud to say that at the moment I have no asus crapware in my system and everything is not just ok, it's much better that when I was trying to use what I found out to be just some marketing BS.
I get to 4.6 ghz with no more then 1.16v (if I remember correctly); I didn't test verry much, just some short benchmarks but that was stable enough for me, as I aim for lower temps and noise levels. You will get better results using bios settings, you just have to do some reading for that.
