Orange Pi 4B fails on benchmarks

[kentAVR]

Armbian (I try a lot of versions include Armbian Focal xfce mainline based kernel 5.10.y) fails on Orange Pi 4B.

 

1. Orange Pi 4B booting normal, I try to do hard job and... it restarting every time after try to do hard job like build Qt or running benchmark and never boot normal again while powered. I need off power supply, on power supply and Armbian boot normal again and goto 1.

 

I use Orange Pi 4B (on pcb v 1.4) with Ubuntu 18 from xunlong (Linux 4.4.179-g4cac54c6-dyrty). It works ok even I build big apps like Qt or run benchmarks. I also building my own Ubuntu 18 using xunlong script and it also working ok.

 

Why I can't use Armbian for my Orange Pi 4B?

My power supply from xunlong is good. Also I try a lot of others power supply.

Do you have a proper heat sink on the SoC?

nope and I haven't box too

 

With xunlong Ubuntu 18 temperature is less 83 °C with hard job and about 70 °C in idle.

[kentAVR]

The problem was in temperature. If temperature > 93  °C system will shuting down.

 

So after start I am goint to

sudo armbian-config

and change CPU's GOVERNOR to savemod.

 

So now temperature is about 80 °C.

I use Orange Pi 4B in room with 25 °C without any box.

 

Is it normal that armbian can't work on board presents as is? I don't understand why armbian wants proper heat sink by default... May be armbian should provide another GOVERNOR by default?
