Its at 10% load which is the perfect territory for turbo boost to kick in, as previously mentioned by Bob.B you should see your clocks bumping up and down, i wouldnt worry about it, my Ryzen 7 3700x is between a 2 and 9% load and it is bobbing between 3.9 and 4.12 ghz on a Gigabyte B450m DS3H V2 board with no special settings or overclock in the bios.
