Guest Posted December 9, 2019 Posted December 9, 2019 Hi All, I am looking for h3consumption utility to change ddr freq (I want to set ddr and processor as low as possible) Could someone help me ? Best Regards, Boris

Works # only with H3 devices running legacy kernel. see also the following thread:
Guest Posted December 9, 2019 Posted December 9, 2019 Thank you for your answer Guidol, I wget the latest h3consumtion script (https://raw.githubusercontent.com/armbian/build/master/packages/bsp/h3consumption) thanks to tkaiser, but it does not fits to Nano Pi Neo. I used armbian-config instead to successfully change processor consumption, but temperature is too high. Reduce the DDR clock is really what I need. I modified script.bin thanks to you,. Thank for your help I added "dram_clk=360" to uboot environment with armbian-config but it does not seems to decrease the temperature.

The Neo has a H3 CPU, but why should a Neo be too hot? My Neo wasnt never too hot or do you run from battery and want to save energy?
Guest Posted December 9, 2019 Posted December 9, 2019 Linux nanopineo 5.3.9-sunxi #19.11.3 SMP Mon Nov 18 18:49:43 CET 2019 armv7l armv7l armv7l GNU/Linux CPU temp: 54°C CPU temp: 54°C Without heatsink it is normal, I think, but with previous configuration I never come over 50° so I try to reach this. What range of temperature do you have ? If I use a closed enclosure, temperature increases to 80° and I stop the board. With h3consumption and a 3.4.113-sun8i I can keep under 50° reducing number of cpu and ddr freq, if I use a closed enclosure, so that's what I try to have.

My Neo is only with the heatsink from FrienlyElec/FrienlyARM and the PCM5102A-Audio-Hat. In the summer I had 53° and now in the winter only 43° running without enclosure - while running ondemand governor 480-1008Mhz My Neo2 is running in the silver NAS-case (they sell) here in the winter also with 45° My NanoPi A64 is running without enclosure and a little heatsink at 32° . Also the OrangePi One does run cooler than 40° with plastic enclosure (but not a complete-closed one) which closed case do you use? the "new" black metal one?https://www.friendlyarm.com/index.php?route=product/product&path=93&product_id=259
Guest Posted December 10, 2019 Posted December 10, 2019 I use my own enclosure (and I will not change) so I try to keep thermal settings back, if someone knows how to downscale DDR reduce CPU number and Freq on a NanoPi neo (like in the 3.4.113 kernel for example with h3consumption), it should be great ^^^^^
