So, it's not totally unusual to hit high clocks on Ryzen and sometimes often beyond what's specced. It's most likely one or two cores can hit higher clocks above what the max boost clock is. I've had this chat with someone, and will try and find a screenshot he showed me, where 2 of his cores hit 4.7 and higher when system was idling, or doing basic tasks. For a split second it's fine, but remember Ryzen adjusts it's boost clocks on the fly, depending on a number of variables, including temps, cooling etc. So if you have a decent cooler, a good chip and a good mobo, it's conceivable the results you are seeing is normal.
Do a couple of things, namely, update bios to most recent for your mobo, all system drivers and software you are using to monitor your CPU usage. I'd suggest using HWMon/info for a broad spectrum of results, and MSI afterburner OSD for in game monitoring.
Also, make sure to set windows power profile to high performance, or download the AMD Performance profile to get the best and most accurate results.
Finally, list your full system specs including Ram/Mobo/PSU/GPU.

You'll see two of the cores hit 4.9 and most others were about 4.5-4.7. This was mostly while system was idling, but seriously, that's insane, given the spec for R2700x is max boost of 4.3
