Just because mem profiles on ASRocks are tested on regular RAM , not cherry picked samples like in ROG boards. I couldn't make to run even 1 profile on ROG or GB OC boards with my memory. Each time I had to lower 1-2 memory ratios.
Anyway I'm used to set everything manually so I don't care much about profiles but they're pretty handy for more regular users who wish to set something more than standard SPD/XMP without learning all timings and trying to stabilize everything for couple of days.
Well, I also have ASRock Z87M OCF and it's a great board. It's auto tweaking some options for optimal performance so the only option that you may enable is performance mode for memory. On my memory it's giving up to 2GB/s higher memory bandwidth.
