Concentrate on getting memory clocked stable at 3600, that's a big help for Ryzen performance.
As said, overclocking Ryzen 3000 is pointless. And Even those who think they're successful actually hurt light threaded performance and that's what helps gaming the most. Be sure to install the AMD chipset drivers, which installs a Ryzen power plan, and set up BIOS right by making sure processor clocks and voltage are on AUTO. Then...
Cool n Quiet ENABLED
Advanced C States ENABLED
Processor CPPC ENABLED
CPPC Preferred Cores ENABLED
If you really really really want to experiment with manual overclocks get Ryzenmaster and the new
Clock Tuner for Ryzen utility. It helps you find a
safe voltage as overclocking can damage the CPU if too high. The 7nm process is sensitive to high currents that high voltage drives in the cores. But the thing to do is run a CB20 benchmark both before and after to see if it improves or degrades performance. The more likely result is similar multi-thread performance and much degraded single thread performance.
