I wouldn't suggest pairing that GPU with that APU, at this moment of time. On another note, overclocking isn't just a magic number you key in or enable a setting, it comes from having a complete package which is your system.
Mind sharing the specs to your build like so:
CPU: Ryzen 3 2200g
Motherboard: B450m-HDV
Ram: Patriot Viper Elite 2x4gb
SSD/HDD: SATA 7.2K 1tb HDD, and a 250gb SSD
GPU: PowerColor Radeon RX 570 4gb
PSU: be quiet! System Power U9 400w
Chassis: Aerocool Cylon Mini
OS: Windows 10 Pro
