Just get a copy of 1usmus Clock Tuner for Ryzen (CTR). Its like 3 clicks to do everything automagically, but betterJust a small piece of advice from my dealings with the Ryzens. I didn't use XMP profiles due to temperatures and power usage. I've set my CPU's (3600 and 3900) to their highest stable limit and set the ram manually to 3600. The core volts are 1.3v maxed. I saw a 15c temp drop on the 3900 and still have some playing around to do on the 3600.
All core on the 3900 is just past 4.3ghz. 3600 is around 4ghz. With XMP on the 3900 I was seeing volts bounce off 1.5.
Some other guys here have gone much further into the overclocking realm with Ryzen Master, a program I didn't like much.
