Cpu is AMD Ryzen Threadripper 3970X

Current CPU speed is 3700 MHz.  Should go to 4550 Mhz.  How do I get there.

Does hwpstate_intel.1 support the AMD 3970X or, is it intel specific as 
the name suggests?

sys/amd64/conf/GENERIC has
# CPU frequency control
device          cpufreq

Should this compile in the cpufreq driver?
