Erik Posted March 3, 2017 Share Posted March 3, 2017 Hi, I did read a lot about temperature and power consumption on this forum. Most is about bad parameters for the Orange Pi H3 boards. I use armbian 5.25 stable with 3.4.113-sun7i kernel. On both i run this same version, the only difference is that i use an other script.bin on the orangepi. The script.bin who is in the distrubution. I dont use a heatsink on both. I noticed the following On the Orange Pi: Load1 is max 0.50 with 2 values of 1.00, avg 0.20-0.25 Load15 is between 0.08 and 0.14 The temperature is between 49 degrees and 52 degrees Celcius The PMU current is between 400 and 800 mA PMU Consumption 2000-4000 mW On the BananaPi: Load1 is max 0.50 with 2 spikes of 0.75 and 2 of 1.5, avg 0.3 - 0.35 Load15 is between 0.14 and 0.16 The temperature is between 38 en 42 PMU current is between 250 and 500 mA PMU Consumption 1200-2900 mW I see that the Bananapi has a little more load, but has a much better powerconsumption (lower) and a much better PMU temperature. My question, which variables do i have to tweak in script.bin to get the orangepi, more or less the same as the bananapi. I ask this because i'm running tests on different boards: I have tested the H3 (OrangePi plus with no heatsink-with version armbian 5.20)on duration with a few programs (see below)and after 2 days 8 hours and 14 min all froze (no input possible) the same after 1 day 7 hours and 58 min I have run one test with the Orange Pi A20 - it stopped after 7 days 1 hour and 56 min. Now im testing with both the Orange Pi A20 and the BananaPi M1 (A20) (I want a board to run day and night - year after year) But i'm a little bit worried about the high temp of the Orange Pi (PS i have ordered heat sinks, but i think this will only lower the temp with about 3 degrees) Just for heaving an idea from the load. What have i installed: -task-lxee-desktop -task-xfce-desktop -xfce -xfce-goodies -icewaesel -samba-common -gvfs-backends -python (2.7) + pyserial -rrdtool -nginx -armbianmonitor -rpimonitor -arduino 1.6.1 on both there is a arduino-leonardo - which gets its power from the pi running: 2 sessions of vncserver a webbrowser nginx an indexpage which is build every 1 min rrdtool building every 5 min 30 graphs, and 4 new html-pages a read from ttyACM0 continously by python and a write to 4 rrdtool databases every 5 min. and a test every min if pyhonscript is running. Thanks Erik Checked script.bin The script.bin is mostly equal. The dvfs_table is. So i think the difference is a hardware thing. So i can do nothing about the greater power consumption. Can only hope Shenzhen Xunlong Software CO.,Limited will do something about this on future boards.
