How can I make Orangepi RV2 actually reach the full 1.5 GHz?

[Johson]

I just installed the official Armbian desktop image on my Orange Pi RV2. When I check with top or cat /proc/cpuinfo, the CPU frequency is stuck at 1.0 GHz all the time. How can I make it actually reach the full 1.5 GHz? Do I need to change some config file or install extra drivers?

As far as I can tell, Armbian does not support the OrangePi RV2.  Where did you get the image from?

 

Or are you really talking about the PC2?  RISC or ARM? Big difference.
