why is my CPU boosting?

[meppips]

Good day Sir/Ma'am.

I built a PC and it's running good.
but i notice that my CPU is running near at max boost clock, but i did not overclock it.
btw i'm just a noob.

this is my spec:
Ryzen 5 2600 (base clock 3.4 & boost clock 3.9)
MSI Bazooka Plus B450M Motherboard
16gb RAM
GTX 1050 Ti
2 x 500gb HDD

and my normal core speed are 3750.3 to 3874.3 MHz based on CPU-Z and 3723 to 3874 MHz based on NZXT CAM.
is this ok or have I done something wrong?

thanks in advance.

It goes into boost mode, when it needs to.
Automatic overclocking. Normal behavior.
