Pi3 B PLUS OverClock.txt

USE AT YOUR OWN RISK!!

How do I determine the current MHz?
Run this in a terminal: 

   sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

It will display the maximum CPU frequence

How can stress test or benchmark?

This will install sysbench: sudo apt-get install sysbench

This command will Run a prime number benchmark to 20000: sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run
