Hi, I just built a new computer and when I got to Task Manager it reads the cpu speed at 2.2ghz instead of 3.8ghz. Though, it does see all the cores and the base clock does say 3.8ghz. Is there a reason it is going slow when I check Task Manager?

DDR4 3200
NVIDIA 2070
RYZEN 9 3900X

The cpu will only achieve such speeds when only required or the tasks demand from the CPU itself.
Open any resource manager tracker and do intensive tasks like heavy CPU game for 10m and check the average.
And it should be the stated= 3.8ghz +/- average.
Or just run a CPU benchmark application while using windows resource manager.

^ What he said.
The Ryzen Balanced Power Plan in Windows lets your CPU idle at lower clock speeds and they only Boost to higher speeds when they are needed.
My Ryzen 5 2600 idles at 1.5 GHz but it boosts to 4 GHz (my OC speed) when necessary.
