Overclocking
You have the ability to overclock from ASRock's software, but to be honest Ryzen Master is probably a little easier and more intuitive to use. The EFI is much easier whether you're going for a manual overclock or heading for PBO/Curve Optimizer/Shaper. As usual these are located in the both the main OC Tweaker section or Advanced section, but if you just want to enable PBO and go, this can also be done from the Easy Mode page, although like the EFI in general, it's not as intuitive as the competition's.
