i would say 4.9 is more testing release. looks like cpu is thinking that it is overheating and preventing 1.8 ghz clock plus removing cores, but if you put some load i guess they should appear. if you do not need hdmi then armbian latest release with kernel 5 version is better chaise there

Hi,
I don't use the hdmi output, my pi is a headless server.
Actually Armbian isn't listed for Orange PI 3 http://www.orangepi.org/downloadresources/

It's not there to limit wasting our human interaction support resources ... but you can build an image, which might just work. "Might" is there because it is still under development.
