orange pi 4 kinetic xcfe 6.0.11 the opp20 from build dont work!!?!! but got overclock to 1.7 1.7 1.7 2.18?? ..tought it was kernel specific but took overlays occ22 from bionic legacy img and it works, it say so ....it wont survive update ,you just need to put them back in your/boot/overlays & re-enable it.
Stress test with heatsink+fan 85°C...hot..
i dont see instability here , just a little more speed.
But its at your own risk.
