There is little or no benefit from OC'ing that generation of Ryzen, the CPU's do a great job with the built-in boost Algorithums. Yes you can set the base core clock higher but the you limit it's boost. I have my Ryzen 2700x for over a year now and have tried soooo many different OC setiings, and while I might get a better benchmark score it made no wrothwhile increase in day to day or gaming,
They are not Intel, they do what they are made to do without much input from the end user. Just enjoy the fact you have a stable and reliable system. If you do want to overclock looking at a few videos is not real preperation, this may help you.

Remember that the CPU is only 1 part of the sytem, RAM, GPU must be able to handle the OC and may also need to be adjusted. Also your PSU MUST be of decent quality and be able to provide a stable and constant voltage supply to your system.
