Hi All!

Is it possible to enable 1.8 Ghz on kernels 5.4.x (stable one) and 5.5-rc2 ?

Thanks in advance!

 

I can easily crash one of my test boards when clocking it to 1.8, while it works stable if limited lower. Perhaps speed can be achieved, but not with current DVFS/thermal settings. Since instability is only rasing spam & more questions and since "you" don't care to help us moderating forum, such experiment is out of the question.

 

Perhaps we rather wait that 1.8Ghz become stable.

 

In general: in case you want some changes to the code, prepare a patch https://github.com/armbian/build It will be accepted or denied - in this case.

If you interested in experimenting with higher clocks you may check these commits which have been removed/altered when switching to 5.4.x

sunxi-current has been patched to run on higher clocks. Build an image from master to give it a shot.

Mine is shortly clocked down to 1Ghz due to functional thermal throttling. A heat sink is mandatory if you want to run it at 1.6 - 1.8

I still believe that there are manufacturing discrepancies with this board since I never experienced significant throttling with my board(s) without any cooling whatsoever.

Proper cooling is up to the end-user anyways.

 

I added a kind of solution for that here:https://github.com/armbian/build/pull/1811

The downside is this should be documented somewhere useful.

Probably here (and in case of doubt all other H6 based boards) below the USB3 hint:https://www.armbian.com/orange-pi-one-plus/#kernels-archive-all

"H6 may throttle fast on full load. Installing a heatsink is adviced."

Mine seems fine.

Tried the same with armbianmonitor -z. The frequenzcy broke down

I guess it depends on which kind of load you apply to the chip. On the whole it seems to do fine.

I put a heatsink as listed here at Pine, left OrangePiOnePlus running for three days now ( idle ) with Kernel 5.6.2 and its temperature was 50-51.

However I just put it now in a more open space and that saves immediately 10 degrees.

 

I added screenshot in which the OpiOnePlus is receiving data , " iperf3 -s " (  10 parr. threads )  and  once sending data ( also 10 parr. threads ).

Now things start to move towards 70 degrees once " armbianmonitor -z " is being executed

 

As as side note it seems the H5 chip runs in idle mode at least 5 degrees lower as both boards are in same location

 

On overall it might be interesting using this board as a VPN/ piHole server
