Open up cpuz and tell us what voltage its showing under prime/IBT/Linx load.
It looks like your using offset mode (Can't be sure, not used an asrock board with that bios) which is a little different to setting a standard manual vcore.
As I said though, see what cpuz says under load, let us know and we can take it from there, you should probably be able to get 4.1 stable at ~1.28v maybe less, maybe more, depends on your chip!
