Operating the H3 in a reliable way (sane clockspeeds) 看全部

bronco, your script works very nice

Here my small real-time temperature monitor:

I will show later my heat sink

Thx for the feedback -- good to hear that the script works. But the 'magic' happens somewhere else: Repairing the moronic overvolted dvfs table Xunlong delivered that is used unfortunately also by loboris in his OS images.

If you repair the dvfs table (this is all the script does) then you won't need a heatsink at all: http://linux-sunxi.org/User_talk:Tkaiser#Tests_without_a_heatsink

It's just the crazy overvolting (that's only needed to advertise the H3 based Orange Pi falsely as "being able to run up to 1.6Ghz") that's responsible for the heat problems Orange Pi users believe they have to suffer from.

BTW: Now that linux-sunxi devs start to support the H3 a fex file to be used with the 3.4.39 kernel we currently have to use will soon appear here:

    https://github.com/linux-sunxi/s ... e/master/sys_config

Of course the insane overvolting/overclocking will be disabled and heat problems will be resolved. The voltages at different operating points are higher than the ones I found to be useful so there's a bit more safety headroom by dropping mine and choosing the linux-sunxi ones). Also improvements regarding the 2 LEDs are included. For details please refer to:

I hope that providers of OS images like @loboris will adopt these settings soon to stop frying your devices. Of course specialities for OPi 2/plus have to be adjusted but cpufreq/dvfs/led stuff can be taken from https://github.com/linux-sunxi/s ... ng_orange_pi_pc.fex when available.
Yeah, i hope so too. Loboris image is great but those settings are crazy.

Hopefully new images will be made including those fixes and also all the great goodies that happend lately (gpu drivers, video decoding accelaration)

Hopefully new images will ...

I hope also that loboris make us a Kernel update, that includes this features.
Thanks for your hard work
